EINSTEIN'S INVENTIONS CHANGED SOCIETY. DISCUSS This essay is going to give a brief history of Albert Einstein, State his inventions and also state how they have changed the society. Who is Albert Einstein? Albert Einstein was born on the 14th of March 1879 at Ulm in Wurtemberg, Germany and died on the 18th of April 1955 at Princeton, New Jersey in the United States of America at the age of 76. Einstein was a physicist, He resided at many countries namely: Germany, Belgium, Italy, Switzerland, Hungary, and The United States of America.
Joseph-Louis Proust was a French Chemist, born September 26th, 1754 and died July 5th, 1826 (1). He was made famous for his contribution in the creation of Proust’s Law—also known as Law of Definite Proportions—which determined, “relative quantities of any given pure chemical compound’s constituent elements remain invariant, regardless of the compound’s source” (1). Proust believed, “chemical compounds are composed of a fixed ratio of their constituent elements irrespective of the methods of production” (2). At the time of his publication (1794), this was not a widely accepted notion. Claude-Louis Berthollet was Proust’s major opponent, which stirred a famous debate.
This new theory of energy transformed physics and opened the way for Albert Einstein's theory of relativity. In contrast to Einstein's Theory of Relativity, quantum theory deals with the tiniest things of which we know of, the particles that atoms are made of, which are called "subatomic" particles. In contrast to Relativity, quantum theory was the work of more than one person. The Theory of Relativity was proposed by the Jewish physicist Albert Einstein, in the early part of the 20th century, and is one of the most important scientific advances of our time. Although the thought of relativity was not introduced by Einstein, his major contribution to it was the recognition that the speed of light in a vacuum is a constant and an absolute physical boundary for motion.
Before we start talking about Maxwell’s Equations, let’s look back into history. The systematic investigation of electromagnetism did not occur until the middle age. Magnetic phenomena were first explored in the 12th century—the magnetic compass, and not considered a novelty. In the 13th century, a France scientist names Petrus Peregrinus de Maricourt found that when a magnetized needle was placed on a spherical magnet it would align itself longitudinally. Tracing the line, he showed that they intersected in two points on opposite sides of the sphere.
Aristotle was correct about his first argument, but his second one was challenged by a scientist by the name of Ptolemy. Ptolemy elaborated onto Aristotle’s idea of the earth being the in the “center” of the universe second century AD. Next, Hawking discusses the accomplishments of Nicholas Copernicus, a polish priest who contributed to science around 1514. Copernicus’ theory (Copernican theory), stated that the sun was stationary and at the center while the earth and other planets orbited the sun. Nearly a century passed until Copernican
Visible light rays and x-rays work in a similar manner, both being wavelike forms of electromagnetic energy carried by particles called photons. “The photon concept was introduced by Albert Einstein in order to explain physical phenomena that could not be understood based on the wave properties of light” (Bensaada, Ouellette, 2011, pg 32). The only difference between both is the energy levels of these photons, which is expressed as the wavelength of the rays. Visible light rays and X-Rays are produced by the movement of the electrons in the atom. Another form of more sophisticated X-rays are CT Scans, computer tomography also known as Cat Scans.
Lillian Harris Mr. Marcum Science, 4 November 2, 2009 In this paper you will read about Isaac Newton’s three laws of motion. Sir Isaac Newton was a British physicist. Many people regard him as the greatest physicist of all time. His work is often compared with that of Archimedes and Galileo. The scientific discoveries that he made have given way to new scientific ideas and realizations today.
Ben Franklin’s role in the discovery of electricity came about when he used a kite, to prove that lightning is really a stream of electrified air. Franklin discovered many things about electricity that steered mere theories in the right direction. In 1747, he propose[d] a model of electricity that proved surprising correct. And at that point it was evident that electricity could in fact move through the air; once Franklin had an understanding of the behavior of electricity, he set about to protect houses from the destructive forces of lightning ("Benjamin franklin's inventions,”). 2.
The Speed of Light European scientists and philosophers believed that the speed of light was infinite until Danish astronomer Ole Roemer (1644–1710) demonstrated otherwise in 1676. In the early 17th century, Johannes Kepler stated that the speed of light is infinite since empty space presents no obstacle to it. Rene Descartes speculated that if the speed of light were found to be finite, his whole system of philosophy might be demolished. Galileo Galilei proposed to measure the speed of light by observing the delay between uncovering a lantern and its observation some distance away. It is not clear whether Galileo ever actually performed this experiment, and in any case his method would have only been able to determine that light speed was infinite or extraordinarily fast.
It is an ingrained in our minds that alchemists believed that lead could be turned into gold and that earth was composed of only four elements, air, water, earth and fire. Alchemists were uneducated, but this in fact would be a negative image. They did not have to ability than to investigate the how's and whys, and any chemical reaction was believed to be a magical phenomenon put forth by the gods themselves. Benefits An interesting discovery in chemistry was benzoyl peroxide. Benzoyl peroxide has aided many
