Newton explained that apples fell from trees by virtue of the same universal attractive natural force that caused the planets to orbit the skies.
In his 1687 book, Philosopiae Naturalis Principia Mathematica, Newton presented complex mathematical formulae that described the observed orbits of the known planets fairly accurately. Newton also provided an explanation for why the attractive force of gravity did not cause the planets to fall in on themselves the way the apple falls to the ground. Since all the planets and stars in the universe exerted mutually attractive force and because there were an infinite number of planets distributed uniformly throughout the universe, there was no "center" of the universe and the planets and stars are all pulled in many directions, all of which, in effect, cancel out their tendency to fall together (Hawking, 1991).
Galileo Galilei:
Almost eighty years earlier, in 1609, Galileo Galilei invented the world's first optical telescope and began carefully observing the planets in the solar system. Galileo noticed immediately that like earth, the planet Jupiter also seemed to have moons orbiting it, which directly conflicted with the traditional belief that all objects in the solar system orbited the earth in the explanation supported by the church. In 1632, Galileo published his Dialogue Concerning the Two Chief World Systems, with the permission of the pope, because Galileo had agreed not to favor the Copernican view over the model proposed by Aristotle, as well as to conclude that God's work could never be fully understood by man (Feynman, 1995; Hawking, 2002). When the book had the effect of convincing people that Copernicus had been right all along, the pope condemned the work, brought Galileo before the inquisitors, forced him to publicly denounce his mistaken views, and condemned the world's first astronomer to house arrest for the remainder of his life (Hawking, 2002).
Albert Einstein and the Modern Theory of Gravity:
In 1905, an obscure Swiss patent clerk named Albert Einstein conducted a series of revolutionary thought experiments in which he envisioned himself riding along on a beam of light in conjunction with which he published a scientific paper on what he called Special Relativity, based on the principle that the speed of light is a constant on nature and that the observations of a hypothetical traveller on a beam of light...
Einstein also had a unique way of viewing the universe. He did not see open space as empty space. He wrote, "Physical objects are not in space, but these objects are spatially extended (as fields). In this way the concept 'empty space' loses its meaning" (Einstein qtd. On Space and Motion). He thought the physical reality of space was simply a representation of different coordinates of space and time. Part
Both of them are very accurate but they do not work together and he tried to solve that problem for the rest of his life. Einstein knew that this problem would have to be solved if we wanted to understand exactly what happened to create the universe in the very first instant of time. If Albert Einstein were alive today, he would also be trying to stop war because he
Albert Einstein, a famously mediocre student, once commented that "It is little short of a miracle that modern methods of instruction have not completely strangled the holy curiosity of inquiry." Many educational theorists and gifted teachers have taken this to heart, and endeavored to create learning environments that reflect innovations that are both intuitive and ingenious. Unfortunately, we often see these same innovations stifled at the High School level. Whereas
Today, being a celebrity is more than just about being larger than life. Celebrities today begrudgingly accept the fact that their lives are going to be turned upside down because of their celebrity. They'll be hounded by paparazzi, their children won't have any privacy, crazed fans will hunt down their homes and hotel rooms, and they'll have very little solitude or peace in their lives. It is doubtful that Einstein
VI Summary As we can see, there are any number of techniques and combination of techniques to improve memory recall. Memory is important to the function and quality of our daily lives. Improving our understanding of how it works, and our capacity to remember things is one way to relieve life pressures. Proactively improving memory recall helps thwart the aging process that works to facilitate diseases like dementia and Alzheimer's disease. Keeping yourself
The Manhattan Project: In 1939, the Army Corps of Engineers established the Manhattan Project at Los Alamos, New Mexico, Oak Ridge, Tennessee, and Richland, Washington. Under the direction of physicist Robert J. Oppenheimer, the three research facilities initiated a coordinated accelerated research into purifying natural Uranium238 into weapons grade Uranium 235 and irradiating Uranium 238 to produce Plutonium239 for use in two different types of fission weapons (Rennie 2003). The other major
