History Of Physics Essay

1635 words - 7 pages

Natural Philosophy also called philosophy of nature comes from the Latin phrase “philosophia naturalis”. Natural Philosophy is the philosophical study of the cosmos and nature’s elements and how the materials around the world are formed. There are many branches of natural philosophy including: cosmology, etiology, astronomy, probability, the study of matter, the study of elements, and many other subjects. The pioneers of natural philosophy are mainly pre-Socratic philosophers; the most famous philosophers of them were Thales, Democritus, and Aristotle. Thales argued that natural phenomena always occurred because of natural reasons; he refused the supernatural or mythological explanations. Another philosopher that contributed to natural philosophy was Democritus. Democritus, collaboratively with Leucippus, created the theory of atomism. While Aristotle, arguably the most iconic of all philosophers during this time period, further promoted the idea that natural phenomena is caused by natural reasons, which meant that it can be studied so that laws can be formed. Aristotle also wrote about metaphysic, poetry, music, physics, logic, politics, rhetoric, ethics, linguistics, biology, zoology, and theater arts. Aristotle also tried to discover the laws of motion and gravity.

The term “Classical physics” is used to describe physics before 1900 A.D. and after 1600 A.D. In classical physics matter and energy became two different things that made up the universe. Matter is anything that occupies space and has mass and must exist in either of these forms: solid, liquid, gas, or plasma while energy does not need space and exists in various forms including: magnetic energy, thermal energy, electric energy, and kinetic energy. Classical Physics is mostly based on the work of Sir Isaac Newton and James Clerk Maxwell. Classical Physics is divided into many subjects including: dynamics, optics, statics, thermodynamics and hydrodynamics, mechanics, acoustics, magnetism, electricity, mass, matter, and momentum. One of the most influential discoveries in the “classical” physics era is the theory that mass and energy can neither be created nor destroyed and that momentum doesn’t change unless an outside force acts upon it. These theories later became the laws of conservation of mass and energy. In a sense classical physics can be described as basic physics, in which broad theories were formed by using basic experimentation and the use of mathematics. Classical Physics laid the foundation of modern physics by founding theories about conservation of mass and energy, gravity, magnetism, electricity, acoustics, and matter.

Isaac Newton, a self-proclaimed British physicist, laid the foundations of modern physics, contributing to its development throughout the progression of time. Newton unraveled the mysteries behind motion. Newton formulated a set of laws revolving around the intriguing nature of motion. His first physical law states the following, "Everything in...

Physics of Tsunamis

968 words - 4 pages Tsunamis are waves, or series of waves, created by a disturbance in the ocean. Most of the time this disturbance is by an earthquake but can be from meteorites, landslides, or even explosions. They are sometimes known as tidal waves but this is a misnomer because tsunamis have nothing to do with tides. While tsunamis are feared particularly in light of the December 26th tsunami, the physics behind them is fascinating. One the largest

The Physics of Boomerangs

1382 words - 6 pages project. They generally have a bit of (undocumented) history/anthropology, some physics, and throwing instructions. For example: http://www.gel-boomerang.com/, and http://www.boomerangs.org/ (pictures of some odd shapes). This is consistent with my experience. Trying to put more spin on the boomerang mainly has the effect of making a throw unnatural and therefore prone to fly into the ground. 7When in college, my daughter would often suggest “going to throw a boomerang” as a first date. Her idea was that she learned a lot about a guy seeing him cope with failing miserably--a certainty the first time out with a boomerang--at a seemingly simple athletic activity.

Preliminary research In order to better understand the physics of fireworks, we decided to investigate the history behind the understanding and conception of fireworks. Originally, fireworks were created in China. The art of combining pyrotechnics and casing them has existed since the sixth century. The Chinese made

This is a very accurate depiction of submarines, as they are primarily used for this, however, they are used in areas of scientific research as well. The purpose of this web page is to go into the history of the submarine to see how it has developed over time. We will also look at how a submarine works, from a physics standpoint

Physics of Fireworks

2827 words - 11 pages After black powder was discovered by the Chinese in the 9th Century, the relatively short history of fireworks began with this explosive chemical composition. Black powder is made up of potassium nitrate, sulfur, and charcoal (KNO3); in the correct amounts, this combination has very explosive results. The use of black powder sprung forth the evolution of muskets, rockets, and fireworks. Although history has shown that the development of black

Guitars are a highly versatile instrument capable of playing full 6 note chords, unlike most instruments. As much as music depends on guitars, guitars also depend on physics. Without understanding the properties sound, guitars wouldn’t be possible. Guitars use the principles of acoustics to produce the sound you hear. Acoustic

Discovered by Galileo Galilei, it remains a fundamental part of physics even today. It states that all objects that are falling, no matter mass, height, or any other determinant, will remain at a constant acceleration (only when disregarding air resistance). This is important because it allows a
