Data confidentiality is one of the three main IT security components which are data confidentiality, integrity, and availability (CIA). To keep your data confidential means to protect your data from unauthorized access. In other words, sensitive data are stored in a protected system that keep these information and data away from attackers and here the data confidentiality will measure the ability of the system to protect its data.

When the clock is moved away from sea level gravity would slightly decrease causing the clock to lose time. Pendulums are the most accurate at sea level.

Then the Indians added their own discoveries with the astronomer Aryabhata expressing an astronomical problem in the form of a differential equation and Parameshvara of Kerala developing an early version of the mean value theorem in the fifteen hundreds.

Today people from around the world are drawn to the mausoleum not only to view the impressive architecture, but to see the Foucault Pendulum. It is one of the largest of its kind in existence. It keeps accurate time as it makes one complete revolution every 42 hours and 48

Although, Aristotle had said that a pendulum swing

Such problems began with the length of the day, the basic division of calendrical time. Technical difficulties associated with measuring time on Earth and ignorance of the true structure of the solar system

Before railroads, time was relative to where ever you were. In every town, the clocks were set to the sun. For stagecoaches--which were unscheduled--this was no problem. The railroad, on the other hand, prided itself in being precise and on the dot. Because of this, the conductors had to consistently change their watches, lest they be on the wrong time. Although this arrangement was manageable, it wasn’t practical or very safe, as if a train was off even by a few minutes it could collide with another one. A man by the name of William F. Allen took notice of this, and decided to try and reform the way we told time. He divided the continent into four zones, and made a timetable that anyone could understand. Using this method, the railroad would

The first cases of what would be considered properly using the Scientific Method can be found earlier, though, back in the studies of Galileo, early in the 17th century. He first observed that heavy objects gain speed as they fall. He then proposed, or hypothesized, that the rate of falling of massive objects was proportional to the distance that the object has fallen. Following the Scientific Method, he tested his hypothesis and found it to be false, since objects falling unequal distances do not fall in the same amount of time, as his hypothesis led to. Since his hypothesis failed, he made a new one, which proposed that the rate at which an object falls is directly proportional to the time the object has spent falling. This was tested by rolling balls down an inclined plane and calculating the speed and time values from those observations. Later, these experiments led to the discovery of the gravitational constant g, and a better understanding of the Scientific Method.

In 1731, as the first mechanical device that used to study earthquakes, Earthquakes that occurred in Naples inspired Nicholas Cirillo ot design this mechanical device. Cirillo’s device consisted of a pendulum that swung freely. The vibrations from the earthquake caused the pendulum to swing.

It was based off of sketches from Leonardo Da Vinci. These sketches were complete enough and accurate enough to convince people that he may have been the original inventor. The German astronomer and mathematician William Schickard was the first to bring this invention into creation in 1623. He planned to have one built for his friend James Kepler. Sadly, this machine was destroyed in a fire. William Schickard and his entire family died during the Thirty Years War. Because of this, the machine is surrounded by a not of mystery. While not being used directly by many people, the calculating clock still played a part in development of technology. This is because it was an inspiration for other calculation devices such as the pascaline, and the Leibniz Wheel. This is why i should not be forgotten by history, as without it these other tools may have never come to be in

Most of these items are related to the study of heavenly bodies and the subject of astronomy. The Celestial globe is used to observe the positions of the stars and other celestial bodies. The Two Quadrant are used to read time, it allows the height of the sun and the angle to the horizon to be calculated. A sundial is an instrument used to measures apparent solar time, by measuring the position of the shadow of the sun as it changes through the day. The Torquetum is an object used to determine the relative position of heavenly bodies and tell the time. According to the experts, the sundials reveal that it is 10:30 am on April 11,1533. This tells us that exact date and time of Dinteville?fs visit to London.

A pendulum is a bob suspended by a string from a fixed point and behaves in an oscillating manner. When released from an angle away from its equilibrium, it swings side-to-side in a periodic motion. The time it takes to complete one full swing is considered the period and the purpose of this investigation is to discover the effect of the string length on the period of the pendulum. This will be accomplished by recording and analyzing data with the use of data tables and graphs.

A simple pendulum consists of a mass that is attached to a string of length ‘L’ that is fixed to a point, in this case, a cork suspended by a clamp stand. This allows the mass to be suspended vertically downwards and allows it to be displayed at an angle that it swings. A period ‘T’ of oscillation is the time required for one complete swing. For this to happen ideally its mass must swing from an angle that is

With his theory tested with pendelums, almost 100 years later, his theory was used for the invention of the pendulum clock by Christiaan Huygens.

2. The time taken for the pendulum to complete 20 oscillations was found and recorded.
