Supporting Empirical Law with Graphical Analysis
INTRODUCTION
Much of the new and impressive science throughout history naturally originates from theory; many great and important mathematical and scientific discoveries come about by excellent thinking. This does not mean that these findings do not have evidence; even Galileo conducted experiments to support his claims.
However many brilliant theorists work in a field, physical science derives certain laws only through experimentation and discovery. An empirical law shows itself to be true not by theory, but by repeated observations and trials. This experiment discovered the empirical law that predicts the period of a simple pendulum through graphical analysis. The length of time taken for a simple pendulum to finish a period cannot be hypothesized on the laws of physics alone. The empirical law of a simple pendulum, which was revealed after experimentation had concluded, written:
T=2.00√l+0
means that the time, T, of the period of the simple pendulum equals twice the square root of the length. It was hypothesized that the data collected would support the empirical, within reasonable percent error. By determining the graphical relationships between different variables and their effect on the period of the pendulum, the raw data revealed an equation.
PHYSICS IN PRACTICE
A huge branch of chemistry, called kinetics, relies on well-established rate laws to determine the progress of a reaction from its
Reaction order and rate laws are key to understanding the speed in which a reaction occurs and the necessary amounts of each reactant in a reaction. Reaction order determines the concentration of each reactant and can be used to calculate the amount of a substance in a reaction. The zeroth, first, and second orders are the most common and were used in this lab. The order of a reaction can be found by comparing the quantity of a specific substance and the rate in which the reaction occurred. Rate laws contribute to the speed of differing reactions. This is a necessary principle in many fields. For example, it is necessary to know the speed of a reaction that goes on during the inflation of an airbag. Without knowing the rate law the speed could
An essential element of chemistry is finding reaction rates. This is because chemists need to know how long a reaction should take. In addition to needing to know the rate of a reaction at any point in time to monitor how the reaction is proceeding.
Lisa Jardine’s Ingenious Pursuits: Building the Scientific Revolution provides a comprehensive breakdown of the discoveries that defined the Scientific Revolution and the history behind them. The story of the scientific revolution truly begins with a separation between the Catholic Church and the denizens of Europe brought on by the Protestant Reformation. This separation led directly to the questioning of the church and what they deemed to be true. The growing suspicion of the church applied not only to the politics and religious views but the scientific “facts” the church was built upon. The suspicion of these scientific facts quickly grew to an open challenging of these facts, The Scientific Revolution. The Scientific Revolution is something we have all studied in our grade school years and the discoveries of people such as Isaac Newton and Galileo Galilei are well documented and arguably common knowledge but Jardine’s book Ingenious Pursuits encapsulates the scientific revolution in a new light. Jardine accomplishes this by telling the stories of some of the greatest achievements of the Scientific Revolution. These stories reveal the collaborations of some of histories most brilliant minds as well as the secrecy amongst them and uncover the motives that fueled many of these accomplishments.
In summer of 1609, Galileo Galilei (1564-1642) pointed his revolutionary astronomical telescope to the heavens under the starry Venetian sky; his greatly important observations unveiled the mysteries of universe and would end up changing the course of scientific thought forever. Galileo lived in an age where there was much status quo, when scientists and philosophers would accept scientific and religious doctrine that had stood for hundreds, if not thousands, of years instead of challenging the accepted knowledge in favor of intellectual progress. Galileo’s scientific methods lead to significant discoveries explaining key scientific laws, such as the
The development of the scientific method in the late 1500’s to the early 1600’s was a crucial stepping-stone in the science community. The scientific method is based upon observations, hypotheses and experimentation. The concept is rather simple, and can be applied to many areas of study. Once an observation is made, the observer can make a hypothesis as to why that phenomenon occurs and can then design an experiment to prove whether or not that hypotheses is valid. Although the scientific method has been extremely useful in the discovery of various things from usages of medications to studying animal behavior, there are still those who question the usage of this tool. These critics claim that since
science a hypothesis is always trying to be proven like Galileo was doing but it
But in the 17th century knowledge in these fields took sharp turns. It started with new science discoveries through observation which did not hold true with the old believes. In astronomy for example, Kepler supported Copernicus’s claims, and believed it could only be understood through mathematical

Also Leonardo Da Vinci’s discovery in the anatomy of the body. He uses pure math and science to discover the body by using circles and squares. This explains that stuff can be proven not by the church but by math and science. The Heliocentric View explains to people that Earth is not the center but actually the sun is the center of the galaxy. This was discovered not by the church but by the people who wanted to know if the earth was the center. This came to be when they notice that the moon was circling around us, which made people assume that everything revolves around us. But didn’t put thought that we circle the sun which is why we get night and day. They also noticed that we don’t revolve in a perfect circle but in an elliptical shape. This was found by using math and not the belief in church. Because of these discoveries we can now assume everything can be proven my math and science and not rely in our beliefs. This explains that for most of stuff we encounter it might be proven by math and

Science tries to posit explanations for our existence here and for the existence of everything around us. No matter how many “proofs” exist though, each has to have derived from some “thought” or “idea” that has no concreteness to it. As Hume first explains in his Enquiry, there are relations of ideas that lead us to justify certain scientific proofs empirically. Kant calls this analytic versus synthetic.
After that theory scientists started Wondering about this theory and a lot of Scientists made up Models and conducted Experiments to Explain this Theory. In this report we will put our self’s inside Each scientist’s Shoe and see What has he discovered.
Although it is irrefutable that both Aristotle and Isaac Newton are great scientists and have made phenomenal contributions to scientific development, their scientific methods vary to a large extent. With reference to Scientific Method in Practice, Aristotle investigated the world by using inductions from observations to infer general principles and deductions from those principles to conduct further observational research (Gauch, 2003), while in Isaac Newton's Scientific Method, the author describes Newton’s method as aiming to turn theoretical questions into ones which can be explained by mathematical ideas and measurement from phenomena, and to establish that propositions inferred from phenomena are provisionally guides to further research
In the natural sciences, theories may not be proven experimentally correct; however, it can be falsified through experimental evidence. Aristotle’s idea of spontaneous generation, organisms descending from inanimate matter, was falsified by Pasteur. As Pasteur’s falsification was drawn from the cell theory, this shows how scientific theories are
