Iodine Clock Reaction Lab Report
Abstract: In this iodine clock reaction, a set amount of a vitamin c solution was mixed with a tincture of,
red–brown, Iodine solution in a starch solution. Immediately the solution becomes clear and lacking in all
color. This is due to the vitamin c molecules binding to the iodine molecules. Thus, initiating a clock
reaction in which the time it takes for a color change is compared with the time it takes to produce a
necessary amount of I2. By alternating between different mixtures and concentrations of the reactants and
measuring the time it takes for the solution to turn blue–black, which comes as a result of the I2 interacting
with the starch, the dependence of the reaction rate of the concentration can be shown. With a greater
concentration of the reactants, H2O2, I–, and H+, in the reaction, the time needed for the color to change
was less. The individual orders for H2O2, I–, and H+ are 1, 2, and 2 respectively. The overall order of this
reaction is 5, and the average rate constant is (k = 0.0544).

Summary of Clock Speed: Winning Industry Control in the Age of Temporary Advantage by Charles H.

Introduction
In order to conduct a scientific study, you set a baseline then introduce changes in order to understand the
impact of the change. Unfortunately, the rate of change, or clock speed, in many studies (human evolution
as an example) is too slow for one person to have time to introduce multiple changes and measure the
results. Biologists have found by studying fruit flies (a rapid clock speed with a life span of days rather than
years), they can reach conclusions faster by studying multiple life spans in a short amount of time. As with
the fruit fly, some businesses also have a rapid cycle making them a prime target for ... Show more content

The author describes this as three dimensional concurrent engineering (3–DCE). The third element (supply
chain) is relatively new for many companies and is not fully developed within their business strategy. In
order to incorporate concurrent engineering into product and process and process design, it is important to
understand the orientation of the industry. For an illustration, the author uses the genetic module of DNA –
the double helix. Similar to DNA, organizations need to map their capabilities along with provider
organizations regarding activities, subsystems provided, capabilities they bring to the value proposition and
the technology contribution of each (Fine, 1998, p. 105). As organizations evolve and the industry changes,
they "move" along the helix from vertical integration to horizontal and back. Many begin vertically aligned
where they provide most all of the key elements. A classic example was IBM of the 1970's. IBM had an
integrated product design with an overall system and service package. As the industry evolved, it moved to
a more horizontal structure using a modular design across multiple suppliers. As such, Compaq beat IBM to
market with new products starting in the mid 1980's; however, the modular structure may also lead to
instability by allowing key providers the opportunity to displace the brand. The author references two

History of Time Telling Machines
The Tick in the Clock New technology often begins with the clear intention of solving an ongoing problem
or satisfying a societal need. Many times, this new piece of technology is simple, such as the toothpick.
Other times, a new technology can be a thing of great complexity, such as a computer hard drive or
Facebook. One piece of technology in particular has changed the way human society has functioned over
the past few centuries. Everyone strives to keep track of time, as more and more technologies arise and give
way to an increased demand for a structured day. In order to do this, one looks up at a clock.
The clock, to put it simply, is a device used to tell the hours, minutes, and seconds of a day. According to
Artemidorus of Daldis, a second century A.D. writer, "A clock signifies occupations and undertakings,
movements and the start of transactions. For men keep their eyes on the time in all that they do," (Dohrn–
van Rossum 17). Not only does a clock keep track of time, it signifies the need for the human race to
organize and control their surroundings, as it has been from the first encounter between technology and the
human race.
The technology of a clock is simple yet varied. The clock's shell is usually made out of brass, copper, tin or
zinc. After the shell is molded the components of the clock are assembled; significant working parts
including the face, arms, power source, gear train, escapement, wheels, mainspring, pendulum and quartz
are all

The Schutz Marke Wall Clock
A treasured time piece in transition to family heirloom. The Schutz Marke Wall Clock is a unique blend of
art and furniture and is characteristic of the German craftsmanship of the 19th century and stopped
production after 1932. Ironically, Louise Pearson (my great–grandmother) purchased this clock in 1932.
The picturesque style of this brand of clocks makes it a centerpiece in the home, as many have them
hanging in their home to this day. "Regulator clocks, sometimes referred to as pendulum clocks, were
invented in the late 18th century in a quest for greater timekeeping accuracy" (. This is a culturally
symbolic timepiece and its character is more enhanced as it is no longer crafted by Schutz Marke. Many
have the clocks hanging on their walls, even without that special meaning they hold for some. My
grandmother perceives this as both functional and symbolic of her relationship with her mother and the
meaning it held for her, and that is why she has one. The intricate details along the sides and in the hands
themselves is amazing. There are many types of clocks made and manufactured but the Antique Schutz
Marke German Vienna wall clock is a classic–a strikingly magnificent work of art. The importance of this
artifact is that the details tell the craftmaker's story from the time period it was created. Its craftsmanship is
just one aspect of its significance, as this time piece brings that connection from past, present, and future for
a family. The particular clock

Iodine Clock Reaction
Introduction:
First discovered by Hans Heinrich Landolt in the 19th century, the Iodine Clock reaction is what is
described as a chemical clock reaction, and today is one of only few known to science. It is useful as a tool
in determining the rate of a chemical reaction due to a marked change in the color of the reacting solution
when a particular reaction has been completed. The process is also practical as an introduction to reaction
rates and kinetics. A solution of hydrogen peroxide is mixed with one containing potassium iodide, starch
and sodium thiosulfate. After a varying amount of time the colorless mixture suddenly turns dark blue
which is one of a number of reactions related to the iodine clock. The positive points of the lab would ...

During the lab, a stopwatch was used to measure the time of the reaction taking place. The eye–hand
coordination of a human simply cannot be trusted to be entirely accurate which is why there was
uncertainty about the accuracy of the stopwatch.Although the conduction of this experiment was
straightforward, it would be better if we had access to more potassium iodide. The concentration of
potassium iodide was too low, and as a result it delayed the time that the reaction took place. For example,
in trial 2, the portion of sodium thiosulfate is higher than potassium iodide's, so the reaction delayed. The
concentration of potassium iodide would be higher if the potassium iodide provided to us was not diluted.
The potassium iodide provided was at a concentration of 0.2 moles and if it were at a higher concentration,
we would've gotten a quicker reaction.As an alternate method for this lab, solid potassium iodide could be
used instead of liquid potassium iodide since the amount of solid potassium iodide can alter the
concentration of the solution. In order to get solid potassium iodide, we would boil liquid potassium iodide,
and as a result, solid potassium iodide would be left in the plate due to the evaporation of

Salvador Dali’s The Persistence of Memory Essay

This paper will take a look at Salvador Dali's painting, The Persistence of Memory, painted in 1931. As the
viewer can tell, this is a story of time and life. The memories start in the background where all is well and
things are straight and calm. Moving on to the cliff, the observer possibly sees a well–behaved teenager.
There is nothing horrible here that leads the spectator to gasp, and the viewer knows this person made it
through that time in their life. Then the picture moves on to the age of about twenty, the memories are fond

The next item that the eye is drawn to is the fly, resting on this clock. Although this clock seems to be
melting like the others in the picture, the fly plays an important part in this painting. Being the painting is
named, The Persistence of Memory, the fly leads the onlooker to think these memories might not be as old
as the rest. Flies are drawn to items that are rotting but still have some nutritional value; this clock is fresh
enough to have more value than the other clocks around it, giving the spectator the thought that maybe
while the clock is a memory, it is not distant and is still brought to the frontal lobe now and then to be
revisited. After looking beyond the focal point, to the left of that clock and even a little bit closer is a pocket
watch. This watch is in a contrasting orange color. This is the only orange used in the painting. The placing
of the pocket watch is strategic, as it too is on the shelf with the most recent memory, but the line and angle
of the shelf automatically pulls your eye to it. The pocket watch is closed and highly decorated with black.
Although, the viewer cannot make out what the clock is decorated in, it seems to convey that this clock is
very important to the scene. The onlooker might even see this as a memory that has not been opened yet.

Nt1310 Unit 3 Assignment 3 Counters
We all use counters every day. Whether it be in our watches, or even something like our washing machines,
digital counters are found in nearly anything that involves timing (Electronics Hub, 2015).
Counters have come a very long way over the years, increasing in both efficiency and complexity. One
example of an early counter is the counter developed by Paul Stillman in 1854. This design had a small
manual crank which would turn a dial by one digit each time it was cranked. Once the first dial had turned
by ten digits, it would then turn the next dial by one digit (in a gradual motion). In 1920, the Veeder
Manufacturing Company made a counter that replaced this manual crank, which would only allow for
turning the dials one digit at a time, ... Show more content on Helpwriting.net ...
As these flip–flops have a positive edge trigger for the clock input, this means every time the clock input
goes from LOW to HIGH, it triggers the flip–flop, updating the Q output to whatever the D input is,
assuming the SET and RESET inputs of the flip–flop are both inactive, which they are in this circuit
(Digital Electronics, 2014). At the start, the D input will be HIGH, because D is connected to the inverted Q
output (PyroElectro, 2013). However, the 555 timer has a HIGH output at the start, but due to the fact the
flip–flop triggers when the clock input goes from LOW to HIGH, the counter still starts off counting from
0, because it takes one count for the clock to go back to LOW then to HIGH again. As the clock counts,
every second count of the previous flip flop will cause the next flip–flop to change state. Thinking back to
simple binary theory, this makes sense. As a digit in binary is double the previous one, every second time
the previous digit changes state, the next digit should change state once. As this is a four bit counter, once
the fourth digit changes state from HIGH to LOW, the counter resets, and counts from zero

How Did John Harrison's Final Clock?
The race to find longitude at sea was a race of endurance, spanning multiple centuries, countries, and
methods. John Harrison's final clock, H4, was the culmination of that race, an elegant, practical, and direly
needed winner. But this race wasn't solo; instead it was a relay. Harrison needed the knowledge and support
of Enlightenment Science and the Royal Society to accomplish what he did. Without past horological
innovation, patronage from the Royal Society, and the experimentation through a voyage to Lisbon,
Harrison's clock would have never succeeded. Two major innovations came out of Enlightenment Science
in England that had a crucial part to play in Harrison's designs. The first came from Christopher Huygens, a
Dutch member of the ... Show more content on Helpwriting.net ...
England offered 20,000 pounds to anyone who could produce an accurate method of finding longitude at
sea. A solution was imperative for "Safety and Quickness of Voyages, the Preservation of Ships and the
Lives of Men", the "Trade of Great Britain" and "the Honour of [the] Kingdom". But with so much riding
on a solution, the board in charge of giving the prize was inundated with hoaxes and false attempts to win
the 20,000 pounds. Besides that, the common thought was that an astronomical solution was the answer, not
a mechanical one. Because of this, for Harrison to get the board to meet and discuss his clock was almost
impossible without support. He took his clock first to Edmond Halley, a member of the Royal Society.
Halley was impressed, and sent Harrison to George Graham, a well–known watchmaker. After a full day
spent discussing Harrison's ideas, Graham agreed to become Harrison's patron, and finally granted him the
funds he needed to make his vision a reality. Once the clock was built he took it back to Graham who
showed it to the Board of longitude and the Royal Society, "...who gave it a hero's welcome". Patronage
was essential for the clock to be built, and without Halley's connections through the Royal Society Harrison
would not have received the finances he needed. With support secured Harrison went on to construct his

How Did The Pendulum Clocks Make The World
The invention of the pendulum clock played a pivotal role in making the world a more global society. Prior
to its invention in 1656, mechanical clocks were extremely inaccurate, making many scientific experiments
impossible due to the lack of a consistent way to measure time. Travelers who needed to determine their
longitude and latitude, such as explorers of the new world, needed an accurate way to determine time.
Watchmaking was considered the pinnacle of technological achievement with only master clockmakers able
to produce accurate ones, fostering a global trade of their craft. Specifically in American history The
Waterbury Clock Company, today known as Timex, became a major export for the country in the 19th
century. Pendulum clocks remained the world standard for accurate timekeeping for 270 years, until the
invention of the quartz clock in 1927.

Which then drove the invention of the anchor escapement around 1670. In addition to increased accuracy,
The long narrow clocks built around these pendulums, later known as grandfather clocks, were first made
by William Clement around 1680, The increased accuracy from these developments resulted in the
implementation of the minute hand, previously rare, to be added to clock faces beginning around 1690. The
18th and 19th century brought many other improvements. Observation that pendulum clocks slowed down
in summer brought the realization that thermal expansion and contraction of the pendulum rod with changes
in temperature was a source of error. This was solved by the invention of temperature–compensated
pendulums; the mercury pendulum by George Graham in 1721 and the gridiron pendulum by John Harrison
in 1726. With these improvements, by the mid–18th century precision pendulum clocks achieved accuracies
of a few seconds per week. (A CHRONICLE OF

Deconstructing the clock Essay
Summary
Ever since the dawn of civilization we have observed time by its natural occurrence and we also relied on
man made primitive tools to measure time. In the beginning, time has always been a natural event, for
example, sunrise to sunset but men's earlier primitive tools to measure time were inaccurate and were only
an approximate indicator, hence often unreliable such as the hour glass.
We became enslaved by the concept of time; our society is controlled by this mechanical device which
dictates our schedule accordingly. Time has evolved from a simple method of nature into a measurable
product which can be sold and bought. The industrial capitalism owes its existence to the concept of time,

Times have progress during 1657 when they introduced the pendulum clock which was sufficient enough to
attain accuracy to have the minute hands and eventually the second hands on the 18th century. These two
last centuries has been crucial for the development of the clock "...capitalism grew to such extent that it was
able to take advantage of the techniques of the industrial revolution to establish its economic domination
over society" (Woodcock 883).
The clock has so much influence on our society, according to Lewis Mumford, an American philosopher,
historian, and teacher "...the key machine of the machine age, both for its influence on technics and for its
influence on the habits of men" (Woodcock 883). This automatic device has attained massive public
importance on our social function and daily lives. The radical influence by this device is apparent, it was
the means of control "...regularization and regimentation of life necessary for an exploiting system of
industry could be assured" (Woodcock 884). We became so much dependent and rabidly time–conscious.
We became like clocks, we developed a routine and a conscious schedule demoralizing our regimentation.
We let the clock set our lives it's about time to apply the true function of the clock as a means of reference
and co–ordination. Men should be free from such dominating regulation "Complete liberty implies freedom

The Doomsday Clock : A Symbolic Representation Of Showing...
At the beginning of Chapter IV, cogs parts appear white on black velvet and then in the next panel stars are
shown resembling the watch parts. This shows that time is forever because the stars that are seen today have
already burnt up and died. Watches, clocks, and time are constantly brought up within the Watchmen
graphic novel . Alan Moore does an exceptional job of showing symbolism and the illusion of time
throughout the novel. Dr. Manhattan, the main character of Chapter IV, wanted to be a watchmaker, but
instead ended up living in a time that may not even truly exist. This includes the Doomsday clock which
symbolizes the coming of an end to time.
A Doomsday clock is a symbolic representation of how close the world is to catastrophic destruction by
nuclear war. At the end of each chapter, a doomsday clock appears that is counting down to midnight with it
first being set to ten minutes to midnight. The doomsday clock serves a purpose as a symbol for the
growing danger and violence in the story. Destruction threatens the world as the clock strokes closer to
midnight. Even though the end is near, the doomsday clock unites the Watchmen in an attempt to save the
world. The blood that starts to appear in chapter III suggests that blood will be shed in the end, no matter
what is done. On page 27 of Chapter XI, a clock in New York is pictured one minute to midnight. On page
28, the faces of the citizens show pure horror and fear; at the bottom of the page is nothing. The

An Analysis Of Cold As Heaven By Judith Ortiz Cofer
"Cold as Heaven" Judith Ortiz Cofer's poem "Cold as Heaven" is a very sweet interaction between a
granddaughter and her dying grandmother. The granddaughter is the narrator. After reading the poem, I
believe the meaning of the poem is that the cold is something that the grandmother never experienced, and
the cold refers to heaven. The grandmother has not yet experienced heaven and she is curious. In lines 25–
30: "When her eyes return to me, I can see she's waiting to hear more about the purifying nature of ice, how
snow makes way for a body, how you can make yourself an angel by just lying down and waving your
arms" (Cofer). These lines describe winter as a place where angels are made. It mentions that even when the
snow touches you, it is a feeling of purification. This symbolizes that heaven is a place filled with angels
that purify you.
The poem consists of many different uses of figurative language in order to connect snow to death. Cofer
included the use of similes to allow the readers to make a connection to what she was saying, so that they
could grasp a better understanding. An example of a simile can be found in lines 6–7: "the Caribbean sun
winds up the world like an old alarm clock" (Cofer). The author is comparing two unlike things, the sun and
an alarm clock, however they have a similar connection. The Caribbean sun is what wakes the world, just
like an alarm clock does. The use of this simile adds to the poem's meaning because it describes the life that
the grandmother lives and that is warmth in her home in the Caribbean.
There is a lot of imagery included in the poem. Throughout the poem I was able to visualize what the author
descriptively shared. The poem includes descriptions of where the grandmother lives in the Caribbean,
where the granddaughter lives with the winter weather, and how heaven looks through the eyes of the
granddaughter's comparison to winter. As I read through the poem several time, I looked for some mention
of Christianity. I found it in lines 1–2: "Before there is a breeze again before the cooling days of Lent, she
may be gone" (Cofer). Obviously, it is a Christian belief that when you die you will go to heaven. I

Iodine Clock Lab Report
"Iodine Clock" refers to a group of reactions which involve the mixing of two colorless solutions to
produce a solution which gives rise to an initial induction period, before a sudden change creates a deep
purple–blue color (http://web.mst.edu/~gbert/IClock/discussion.htm)
For the reaction to occur, certain conditions must be met.
When starch is mixed with iodine in water, an intensely colored starch/iodine complex is formed
(http://antoine.frostburg.edu/chem/senese/101/redox/faq/starch–as–redox–indicator.shtml).
This is because an iodine molecule slips into an amylose coil, part of starch, to create the blue–black color.
The time delay until the appearance of the blue color is inversely related to the rate of the

Landolt Iodine Clock Reaction
A clock reaction is a chemical reaction during which one of the chemical species, the clock chemical, has a
low concentration for a certain time before a rapid increase in its concentration marks the end of the
induction period. This accelerated growth can produce effects such as sudden dramatic colour changes in
solution phase reactions (Preece, Billingham & King, 1999). The Landolt Iodine Clock Reaction is a well–
known example and can be described by the following processes: IO3–(aq) + 3 HSO3–(aq) → I–(aq) + 3
SO42–(aq) + 3 H+(aq) IO3–(aq) + 8 I–(aq) + 6 H+(aq) → 3 I3–(aq) + 3 H2O(l) I3–(aq) + HSO3–(aq) +
H2O(l) → 3 I–(aq) + SO42–(aq) + 3 H+(aq) 2 I3–(aq) + starch → starch blue–I5 –(aq) + I–(aq) For the

The work resulting from this branch of science has led to the conclusions that some chemical reactions
proceed in a single step while others such as the Landolt Iodine Clock undergo multiple phases. By
measuring the rate of a reaction it can be determined whether the reaction occurs in one or more steps
(Laidler, 2008). Specifically, the rate of a reaction is the speed at which the reactants become products, and
is affected by multiple factors including temperature, surface area, catalysts and concentrations; the higher
the concentration of a substance, the faster the rate of the reaction (Science Buddies, 2018). The
relationship between the rate of a reaction and the concentration of the reactants is demonstrated through a
rate law. This can be determined experimentally by varying the concentrations of both KIO3 and

in a single dream sequence, the theme of humans turning into machines and vice versa is present throughout

Georges Melies (Ben Kingsley).Time has stolen everything from him, and only a broken shell of a man is
left in his place.He struggles to come in terms with the current times, where his life's work is reduced to
nothing but a pair of shoe heels.

narrative device that propels the plot forward.When the grumpy old toyshop owner takes hold of Hugo's
book on the automaton, and later on, when Hugo 'fixes' the automaton and it signs the name Georges

it many a times.His quest is not only to fix the broken automaton, but also to fix his own broken

Is Discrimination Killing America?
Is Discrimination Killing America? Eric Brene once said, "The moment a little boy is concerned with which
is a jay and which is a sparrow, he can no longer see the birds or hear them sing." This quote is not only
powerful and alarming but it too can shed some light on the situation here in America regarding
discrimination. Discrimination is a plague of society that has cast a shadow over this country and has
caused tension among us in the process. The question remains: is discrimination killing America?
Discrimination is defined as, "treatment or consideration of, or making a distinction in favor of or against, a
person or thing based on the group, class, or category to which that person or thing belongs rather than on
individual merit," (Dictionary.com 1). This debate over whether or not discrimination is killing America is
more prevalent now than ever, with the case of Ahmed Mohamed. Ahmed Mohamed was simply a 14–
year–old student, who brought an invention that he worked so hard and diligently to produce into school,
and ended up in prison. The reason as to why he was put in handcuffs and taken from school: a clock. A
homemade clock in which he made, and brought into school to show one of his teachers, caused Ahmed to
be arrested. There is heavy debate as to whether or not the clock did look a bomb, but without a shadow of
a doubt, that the clock was labeled as a bomb due to Ahmed's nationality. This raises a concern that this
country is on a downwards spiral regarding

How The Watch Evolved From Portable Spring Powered Clocks
A watch is a small timepiece, carried or worn, that is designed to work despite the motions based on a
person 's activities. The watch evolved from portable spring–powered clocks, which first appeared in
Europe during the 1400 's. The function and use of the watch has developed greatly since its establishment
in the early 1500 's. It has evolved throughout the years with multiple purposes of function, mechanics,
production, style, and use. The practice and accuracy of time measurement has made substantial
improvements in history. More than 30,000 years ago time was first recorded by the phases of the moon.
Since then groups have used the sun, stars, flow of water, burning of candles, sand, mechanical devices, and
many other ways for their search to discover the most accurate way in time measurement. Time is measured
using a sexagesimal system, a numeral system with sixty as its base, discovered around the third
millennium BCE. This was first developed by the ancient Sumerians of Mesopotamia, used to measure
time, angles, and geographical coordinates. As other ancient civilizations adopted this method, their
involvement would help contribute to the improvements and accuracy to the modified system still in use
today. Our current civilization can calculate a single day down to the precise hour, minute, and even second.
Published in 1960, the International System of Measurements can base the unit of time, the second, as

John Harrison: Legends and Legacies
The legends and legacies of our world have shaped society and have impacted our daily lives and will
continue to for centuries. John Harrison is one of many legends and legacies that has shaped our lives. John
Harrison changed and developed technology in an enormous way that saved numerous lives and still affects
how we live and travel today. John Harrison's developments in technology of time keeping and longitude
and latitude coordinates created the legacy that he improved society for which he will be remembered
forever.
John Harrison was born March 24th, 1693 in Foluby, Yorkshire. He was the oldest child of a carpenter and
a joiner. John Harrison had little formal education but was a clock maker and the son of a carpenter. He
married his first wife Elizabeth, in 1718. She died eight years later and he remarried to another Elizabeth ...
Even though John Harrison did not have the advantages of a formal education so he used his knowledge
from his father about clocks to his advantage. John Harrison's knowledge from his father led him to create
the chronometers that led many people on many safe journeys. John Harrison's son William followed in his
father's footsteps also by helping him in creating the chronometer. John Harrison had a huge impact on
society especially for fixing "The Longitude Problem" which still has effects society today and we wouldn't
be able to travel through space. Before John Harrison created the chronometer it was thought that you could
only tell longitude by looking at astronomy, but the problem was if you were sailing on a stormy night that
you cannot see the stars and you would get lost. IN fact, it was John Harrison's arch nemesis's theory that
you could tell longitude by looking at astronomy which John Harrison proved to be false. John Harrison
discovered the chronometer that contradicted this

Globe's Most Precise Atomic Clock Invented
Globe's Most Precise Atomic Clock Invented
Time is an adventure that humans seem to be preoccupied in for everything from when we get up in the
morning, when we go to work and when we go to bed, but if you compared all the clocks and watches of
the world, there's a new atomic clock out that is so accurate that it will only lose one tiny second in a
timeframe of 15 billion years!
Apple may have invented its new Apple Watch, but this new optical lattice clock, or it is also being called
the strontium atomic clock, will put it to shame when it comes to accuracy. The new atomic clock was
created by scientists from the National Institute of Standards and Technology (www.nist.gov/index.html),
last year, but now they have adjusted it to the point where it is the most precise atomic clock in existence. ...
When it comes to defining precision in this case, it means how close the new atomic clock can get to the
actual frequency in which the strontium atoms inside of it resonate and oscillate in–between two electronic
energy levels.
In this case, this new atomic clock is so precise that it can even measure how the passage of time changes at
higher levels of elevation on the Earth, as clocks will actually tick faster if you travel to a higher elevation
area. This fact fits in with Einstein's theory of relativity (en.wikipedia.org/wiki/Theory_of_relativity).
According to the scientists who created it, this means the clock can measure gravitational shits if you raise
it up a mere two centimeters from the surface of the Earth.

A Report On Tick Tock
Tick–Tock
1 Every day brings a new surprise and this day sure brought a good one. The thing that I dealt 1with that
day was something I never would imagine happening to me or anyone in a million years. I
2 was home with just my two brothers. It was an ordinary summer afternoon. The wind blowing, the 3birds
tweeting. Not a problem in sight. Until I took a short nap and rose a few hours later. My eyes 4quickly
opened to a vexatious sound. A continues ticking which messed with my head. Tick–tock 5tick–tock over
and over again. I took a deep breath and calmed down for a second. Then, the 6monstrous noise hit me
again. I couldn't take it anymore. I got up off of the bed and intensely ran into 7my brother 's room.

29" KATIE!!!" Wade screeched.
30Ignoring Wade once again, I hustled down the stairs. I expeditiously left my house, slamming 31the door
behind me. Out in my dad's garage, I grabbed a hammer and then dumped the bag of 32watches out on the
floor. I deathly gripped the hammer and smashed each watch one by one. After I 33had finished, I piled the
watch scraps back in the bag and grabbed a shovel. I ran to the side of the 34house and dug a small hole
where I buried each and every watch. After I was done, I returned my 35items and went back inside and I
swear that the ticking went away for a few minutes, but the 36moments of glory didn't last long. Suddenly,
the deplorable sound started again. I cringed. I took a 37deep breath and thought for a second. Then,
something in my kitchen caught my eye. A clock. 38How could I not know that a clock in the house was
making the noise! Relief struck me like 39lightning, powerfully and quickly. I skedaddled and grabbed the
clock I had originally spotted. After, 40I collected the few other clocks that hung in my house. Once more, I
flew out the door to get the 41hammer. Just like before, I smashed each clock to its death. Just like you do
to people, I buried the 42clocks right by the watches I earlier put in the ground. When I walked back, I had
high– hopes that 43the ticking would be gone, but this time it didn't even go away for a second! Right when

Abstract–Power reduction is an major challenge in the integrated circuit design since it degrades the chip
performance the reliability. Frequent transistor switching caused due to large IR–voltage drops gives raise
to timing violations and logic failures. A new clock control strategy is been introduced in this paper such
that the simultaneous switching of the combinational paths is minimized. This is achieved by clustering the
delay slacks having similar slack values. Once the paths are identified based on the path delays and their
slack values the clustering algorithm determines the path to clusters in a load balanced manner based on the
slack values and each cluster will have a phase shift possible on its clock depending on the slack.
INTRODUCTION
Low power has emerged as a major goal in today's electronics industry. The motivations for reducing power
consumption differ from application to application. For high performance, portable computers, such as
laptop and notebook computers, the goal is to reduce the power dissipation of the electronics portion of the
system to a point that is about half of the total power dissipation (including that of display and hard disk).

Huygens Accomplishments
While he was not observing the stars, one problem that plagued Huygens throughout his life was that of
time. In 1658, he was the first to build a pendulum clock –– the first great step towards modern timekeeping
(Magill et. al.). He published the schematics and his speculations about future improvements in his
Horologium in 1658. While this solved the problem of keeping time, one of the most important applications
of this technology continually evaded him. In order to reliably determine ones latitude while at sea, some
form of accurate timekeeping is needed. As a citizen of the Dutch Republic, whose economy was heavily
dependent on shipping via the sea, Huygens was especially desperate to solve this problem. However, when
he sought to apply ... Show more content on Helpwriting.net ...
Huygens was one of the first scientists to recognize that the speed of light must necessarily be a finite
quantity, and from this he was able to determine a kinematic theory of light. The theory details spherical
waves which emanate at the speed of light (which Huygens did not explicitly define other than saying that it
was a finite quantity) in uniform wave fronts. Huygens' spherical light waves propagated in a longitudinal
fashion, and thus must necessarily have a medium through which to propagate. Huygens envisioned this
ether was "composed of tiny, closely spaced, elastic particles, which vibrate and pass on the waves of light"
(Charles). However, not all of Huygens' contemporaries agreed with his formulation of the wave nature of
light. Isaac Newton, in particular, was a vocal opponent of his theory in favor of his own 'corpuscular'
theory of light. Huygens, as stated in his Ebscohost Biography: "...regarded the transmission of such
particles through empty space to be mere Newtonian "action at a distance" again and incompatible with a
mechanistic view of nature". However, Newton's prominence at the time meant that Huygens's theory of
light remained relatively unknown until mid–19th century, when it was rediscovered and eventually
reformulated into what we now know as the Maxwell

How Did The Ancient World Sundials Work?
Over view
In the ancient world sundials were commonly used as a method of measuring time, however, it had its
flaws. Sundials would, of course, would only function when there was sunlight, and they could not be used
at night or on a cloudy day. To compensate for these shortcomings, the water clock was invented.
Around 325 BC, water clocks began to be used by the Greeks, who called the device the clepsydra ('water
thief').
How does it work?
In an outflow water clock, the inside of a container is marked with lines of measurement. Water leaks out of
the container at a steady pace and observers tell time by measuring how much the water level has changed.
For instance, if it takes one hour for the water level in the container to drop down one centimetre, then a
three–centimetre drop in water level ... Show more content on Helpwriting.net ...
Either way, the measurement vessel is often bowl–shaped to ensure that it fills up gradually.
What was it used for?
One of the uses of the water clock in Greece, especially in Athens, was for the timing of speeches in law
courts. Some Athenian sources indicate that the water clock was used during the speeches of various well–
known Greeks, including Aristotle, Aristophanes the playwright, and Demosthenes the statesman. Apart
from timing their speeches, the water clock also prevented their speeches from running too long. Depending
on the type of speech or trial that was going on, different amounts of water would be filled into the vessels.
A Greek astronomer, Andronikos, supervised the construction of the Tower of the Winds in Athens in the
1st century B.C. This octagonal structure featured a 24–hour clepsydra (water clock) and indicators for the
eight winds from which the tower got its name, and it displayed the seasons of the year and astrological
dates and periods.

Argumentative Essay On The Doomsday Clock
The Doomsday clock is a man–made clock created by a scientist by the name of Martyl Langsdarf who
worked in the Bulletin of Atomic scientists. The clock was made initially created by concerned scientists on
the nuclear bomb and its implications on society. There were several different ideas proposed to measure
how close mankind was to its destruction, but the clock was chosen as the most suitable one. [11]
The idea which prevailed was that nuclear weapons would bring about the destruction of human race sooner
or later and the clock was a measure of how close mankind was to its destruction. The clock indicated that
the closer the time is to midnight. the nearer mankind is to its destruction. The minute hand moves forward
and backward depending on the social and political circumstances [12]. The clock is not a matter of
physical nature but human perception of Doomsday. The Doomsday Clock proves to be a cautious reminder
for leaders of the world to ... Show more content on Helpwriting.net ...
The neo–nationalistic approach has led to tensions and intolerance rise amongst countries. Political point
scoring amongst some democratic leaders of nuclear capable countries consists of threats of nuclear warfare
with the hostile countries. In all the events, diplomacy has taken a back seat and threats of nuclear attack is
replied with a similar threat instead of back door diplomacy on issues [18].
The dependency of the clock in recent times is not connected to global changes but rather statements and
gestures of individual leaders. Countless efforts have been taken by the Bulletin of Atomic Scientists to help
reduce the global threats for example efforts of proposing to opt for the Iran Nuclear deal in order to reduce
pollution or the efforts to stop North Korea in testing the nuclear missiles.

I Am A New Alarm Clock
YESTERDAY– (3.4)
I awoke to hear my alarm going off, an audial reminder that it was 6:30, time to begin my day. Lazily I
stretched out my hand, fumbling about trying to search for the snooze button, while all along the vociferous
rhythmic beeping continued. Finally with a burst of energy I sat up, and slammed the snooze button. I
needed to get a new alarm clock, one with all the latest bell and whistles although my alarm was perfectly
satisfactory. George got this new alarm clock with smart phone connectivity ... and won't stop talking about
it, until I get mine. My day continued as normal, turning on the T.V as I dragged myself to the bathroom,
catching a glance of the new iPhone ad before I stepped into bathroom. Turning on the shower on full blast,
hot water streaming down, I closed my eyes. I felt drained although I had just awoke. Work was tedious and
after working so hard, all I could now focus on was my trip to London next week, flying first class to
purchase designer furniture for my new house. Everyone at work would be red with envy, once they heard
about my trip. I heard London is big for its designer clothes, a perfect place for me to spend some money,
buy a new wardrobe maybe.
I abruptly turned off the shower and opened my eyes, I was going to be late. Hurriedly I got dressed, which

Descriptive Essay About A Museum
On September 10 I decided to go to the Hirshhorn museum and sculpture garden located in the national
mall in Washington DC. I went along with my family because I would have been by myself on this amazing
adventure. The museum was originally endowed through the 1960s with the lasting art collection of Joseph
H. Hirshhorn. He expanded his collection of other states such as New York city and Connecticut with
extensive area for sculpture. In 1962 Joseph Hirshhorn's paintings circulated Italy, Israel, Canada, and
California state. The building itself is a three–floor museum, an open cylinder elevated on four massive
legs, with a large fountain occupying the central courtyard.
The Hirshhorn museum and sculpture garden was conceived as the united states' museum of modern–day
and contemporary artwork and presently focuses its series–constructing and exhibition–making plans on the
submit–world battle II period, with emphasis on artwork made during the last 50 years.
First, the exhibition I will discuss is the world time clock by the German/Iranian artist Bettina Pousttchi.
During 2008 and 2016 she traveled around the globe, creating the world time clock. Her photographs
consist of a clock showing different time zones from cities such as far–flung as Bangkok, Auckland,
Mexico City, and Tashkent. The artist's images represent imaginary global synchronism. The exhibition has
been in the museum since last June and will continue to be there till May 2017.

Sleep Deprivation And Women's Circadian Clocks
The silence of the night was peaceful and calm until a shrill sound cut through the air. BEEP! BEEP!
BEEP! It was 6:00 am and the alarm clock you had set the night before at midnight had gone off. As you
trudge around through the day nodding off while working and when you are awake not being able to focus
on the task at hand, you tell yourself you will get more sleep tonight. Alas, the cycle will inevitably repeat.
Many Americans struggle with this problem and often do not recognize just how important it is to get a
proper amount of sleep. Unfortunately, the health problems(both physical and mental) of sleep deprivation
can be more severe than many people realize. Sleep has always been important to health. In recent years the

Today the average Circadian rhythm for adolescents is to begin sleeping at 11pm and to wake up at 8am.
About ⅔ of high school students get less than the recommended eight hours of sleep per night and ⅖
students claim they get 6 hours or less of sleep. "Since the 1990s, sleep researchers and other health
professionals have been telling us that these early school hours are harming children. It's not just the
numbers of hours of sleep, but also the timing of sleep that is required for optimal health." (National Sleep
Foundation) The lack of sleep can give way to health problems such as weight gain, cardiovascular
problems, mood swings and even can affect brain development. Some school districts have begun to have a

Unrealism In Salvador Dali's The Persistence Of Memory
In art, the details and elements involved help create meaning. Without the elements of art, people could not
interpret the meaning of the artwork. The painting called "The Persistence of Memory," created by Salvador
Dali, uses shapes, background, lines, focal point, eye movement, texture, and value to make the statement:
Time will melt away eventually no matter what happens. The importance of "The Persistence of Memory"
stems from the history of Salvador Dali and the 1930s. For example, the artwork demonstrates Einsteins'
special relativity theory, which suggests that time exists as a relative concept and not a fixed concept. In
addition to possessing the traits of surrealism, the artwork also gives a sense of realism. The realism
depicted in the images shows how the images can more likely exist in dreams than while awake. In fact,
"The theme that time is melting came when Dali saw a runny piece of cheese on a hot August day, thus
giving him the idea to form the melting clocks" (Puchko). To help illustrate the theme, Dali uses several
elements of art, such as shapes. Shapes hold importance in illustrating the meaning of art. The shape of the
three–dimensional object, for example, illustrates a rectangle, making it look like the objects sitting on it
exist higher up than the rest of the artwork. The tree looks like a thick line of bark with a thin line of bark
branching off of it, which gives it the appearance of holding up the clock. The clocks exist in the shape of

The dream kept repeating itself and every time the woman would become a much more prominent figure in
his mind. She seemed to be a sort of beacon of hope that he had been longing for these past two years. His
mind as a detective knew that there was something there and he would not stop until he found out what it
was.
He tried many times to reach her but he failed. He tried until one day he was able to catch up to her and to
his surprise he did not wake from his dream. Whenever he would reach the end and the woman was within
arm's reach Max would find himself woken up by either his alarm clock or the ringtone that warned him his
boss was calling. When he approached her his senses were awestruck. Her hair was raven–black. It flowed
in waves to adorn her porcelain–like skin. Her eyes emerald green eyes seemed to shine on their own. She
was the picture of perfection, or in his words, "imaginary."
"Are you the one that chases me?" she asked, her voice was rich and elegant but with an edge of power that
Max hadn't noticed until now. Max normally wouldn't stammer in a situation like this but he couldn't find
what words to say. "Come to me," she said, "why is it you hesitate? Are you afraid? I will free you from
your suffering and sever the chains that make you feel guilty because you did not do that on purpose" she

Lime or soda must be poured on the contaminated floor and it must be cleaned until the floor gets dry.
While using pipette during an experiment, the starch solutions must be pipetted using the rubber suction
bulb, the solutions must not be pipetted by mouth. After checking the color and time, all the solutions must
be disposed in the aqueous residue bottle.
Theory
Iodine Clock is the reaction which includes the colorless compounds and after mixture, observance the
appearance of color in the solution: dark blue/purple. The color, depending on the temperature and the
concentration of the substances which react with one another, appears in a short time interval. Rate of
reaction for the experiment is calculated in the equation given below: reaction rate=k×〖[A]〗^m×〖[B]〗
^n

Here, m and n are called –reaction order, k is called– rate constant which depends on temperature.
There are the factors that can have impacts on the reaction rate of the compounds. As mentioned in the
collision theory (John Green & Sadru Damji), (Green, 2014) these factors involve the concentration of
substances. This experiment will also determine the concentration of H_2 O_2 on iodide

Landolt Clock Reaction Lab Report
DISCUSSION
By analysing the results of The Landolt clock reaction, and the outcomes that occur due to change in
concentration and the addition of a catalyst, the data did partially support the hypothesis. That by changing
the concentrations of potassium iodate and sodium bisulphite the rate of the reaction will increase. The rate
gradually increased per every 10 seconds on the NaHSO3 graph. Whereas compared to the KIO3 graph the
rate was more efficient, the reaction was achieved within 5 seconds. However, the second hypothesis
regarding the addition of a catalyst, displayed acceptable results. The catalyst increased the speed of the
reaction within 10 seconds, which was slightly faster than the reaction times gained from the ... Show more

The tests that had large amounts of distilled water had a long reaction rate due to the breaking of the
molecular compounds within the reagents.
Secondary data states that the rate law yielded from the iodine clock reaction was "rate = k[IO3] 1 (Lyle,
Department of Chemistry) which was different to the rate law that this investigation obtained. 0.41
[KLO3]^2 [NaHSO3]^2. This would have happened due to the changing of both KIO3 and NaHSO3, and
also by adding more distilled water to the mixture which slowed down the reaction rate.
Rate law is important, when regarding iodine clock reactions. The rate law helps to determine what factors
impact the rate, and increase the reaction time. Also helps show what factors decrease the reaction rate.
There were some limitations that were encountered during the experiment, and the planning stages. Such as,
the constant changes made to the method. The method had to be changed three times this was due to scaling
back the measurements of the solutions. The solutions that were part of the original method would have
resulted in 20 ml of the blue solution, which would waste the sodium bisulfite and potassium, every time a
test was conducted.
Another limitation was the trial testing to see whether the experiment worked, which produced efficient
results. Compared to the actual experiment data, many tests had to be repeated. This would be due to minor

Everyone I know has already seen a clock reach zero. A timer constantly floating over somebody's head,

different for everyone. The floating numbers have never dropped that low for me. When Maria sees
someone's timer reach zero, that person sneezes. Steven watches a clock bottom out as the person with that

what the countdowns they saw meant, seventeen years of people swearing up and down that I'd see what

remember my first time, where I would be able to relive the excitement. I never told her that my clocks
aren't counting down. Of every person I've ever talked to, they've never seen their clocks count up, or
freeze, or bounce between times. Oddly enough, none of them ever caught on that I was asking to see if I

opposed to the clothes and the fabric would be easier to clean. This is still one benefit of starching clothing
and one reason why starch continues to be used for dry cleaning..While most starches are broken down by
your body into glucose, some starches, known as resistant starches, pass undigested into your colon. These
starches function much like dietary fiber. They provide nutrition for the beneficial bacteria in your colon,
keeping them thriving and healthy. There are four types of resistant starch. The first is found inside the
indigestible cell walls of plants. The second is considered indigestible unless it is heated. The third is
sometimes called retrograded starch, as long cooking times followed by a cooling period make them more
difficult to digest, and the last is industrial resistant starch. This last type of starch is chemically modified

The Idea And Features Of The Alarm Clock App : Wake Up Ul
Introduction
There are four main factors that we have to focus on this project: the idea and features of "Wake Up UL;"
researching and advertising process; safety and liability, patenting, competition, and product design; and a
financial plan. In the introduction about idea and features of our alarm clock app: Wake Up UL, we have to
make an online survey through http://surveymonkey.com and receive fewer responses than we expected,
causing inaccuracy in analyzing the demand and need of the product as well as the UL community's
interest. Secondly, to make our product stand tall and look good in the current market of alarm clock apps,
we need to create more powerful features that our app can offer such as multiple–choice questions,
matching objects and remembering path–structure to turn the alarm off. Our app is a combination of
features from separate current products, leading to potential copyright–conflicting issues. For our own, we
only have ULL connected network where app users can download their classmates' question banks and use
it. Last but not least, to catch users' attention, we have to come in with strong willingness and beneficial
purposes of our app to serve the UL community. Our app serves the community not only as a usual but
powerful alarm clock app that actually force users to wake up, but also as a new tool that can test users
knowledge, build up their credits, build up their relationship, and strengthen our UL community. Catching

The Long Case Clock Hit Nine
The long–case clock struck nine, "Bing Bong, Bing Bong". As I approached the narrow staircase, the sunset
glistened through the partially opened lunette, a cool crisp autumn breeze gently ruffled my hair. I grasped
the railing taking my first step up the unsteady staircase, my hand entangled in cobwebs. At the top of the
stairs stood my great grandfathers long–case clock. The mechanical gears could be heard sliding against
each other, the rhythmic ticking of the pendulum comforting. As I made my ways to the top, the sunset
reflected off the pendulum, shinning a vibrant ray of light off my grandmother 's vintage wallpaper and
down the hall to the guest room. My eyes become weary, the rhythmic chorus of the clock became
mesmerizing filling my heart with sounds of connection, comfort, and security. Nightfall had approached. I
opened the large double hinged pine window that was perfectly centered in the middle of the guest room
and climb into the old brass bed. My head fell into the softness of the pillow, my body stretches releasing
all my worries and stresses from the day. The warmth of my grandmother 's hand knitted blanket grasps my
body from interacting with the psychical world. I lay there and listen to the sound of the leaves rustling
outside the window, and in the distance I can hear my grandfather 's clock "Tick,Tick". I close my eyes,
unable to see the outside world, my mind drifts into a dream world without thought. It was the middle of
autumn, a festival of fall

How Did The Clock Impact The Ancient World
Many of the greatest inventions ever to be created were coined in ancient China. Soap, gunpowder, even

to brush your teeth, everything! The world runs completely on time, and it's all because of a certain man
who changed the course of the future by just wanting to find out how to tell time more precisely than

Yi Xing, the inventor of the first clock, originally invented it for horoscopes, astronomical purposes, and of
course the time of day. Now, of course, we use it for much more then that. The whole human society runs
by the clock, and without the development of this specific clock, time would be completely different. It
would be like missing the first step on the stairs. You would fall down them and land on your face. Where
would that put time now? Would we still be stuck on sundials and shadows? Maybe people would have
abandoned that time set, and adopted a whole other system of time. People would have different intervals of
time, different ways of telling time, different everything! However, the clock was made, and so no one even
notices because they are too busy running off to the next place. All because of time. Too bad Xing's clock
didn't make time longer! The clock Z=Xing made is very important for today's society. Even if it was too
futuristic for its time and wasn't used too often, the design for this clock was used time and time again, and
it developed into the clock we know

Punctuality And Its Effects On Our Lives And Functions On...
Ever since I became an adult, I have struggled to show up on time. I have been habitually late to
appointments, special occasions interviews and even jobs, to name a few. To make matters even worse,
punctuality is listed on my resume. Being late is obviously highly unfavorable and inconvienient in a world
that lives and functions on schedules, clocks and time zones. "A recent survey found 15 to 20 percent of the
U.S. population is "consistently late," especially when it comes to work. (ABC)" "Who are America's least
punctual workers? The poll suggests millennials tend to show up late more often than older colleagues. 22
percent of them said they arrive late for work at least once a week compared to just 15 percent of people
aged 55 and older. A mere 38 percent of millennials said they never arrive late for work compared to 55
percent of older workers. Considering the fact that I am a millennial, my continuous problem with
punctuality makes sense. According to the polls, of those who are late, millenials tend to arrive to work
later than people who are older. According to a recent survey, around 15 to 20 percent of the United States
population struggles with punctuality, especially when it comes to getting to work on time. Both statistics
apply to me as I am a millennial who has been late to work and late to occasions that were non–work
related. Although I've have a recurring problem with punctuality, this problem can be solved easily. I have

Flashing lights are used to alert users of a doorbell, phone call, or emergency. These flashing systems cause
a dedicated light to flash in response to the action. A whole house can be wired so that one might be aware
