Relativity

Relativity is a theory in physics that can be basically implies that space and time are one in the same. This is absolutely counterintuitive to classical physics which has the two as completely different entities. Relativity can be separated into two basic concepts: Special and General Relativity. Within Relativity the fundamental concept above all else is that space and time are intertwined with each other in the universe as a fabric called space-time. Simply put, Special Relativity deals with the

Introduction: Linguistic relativity is the notion that language can affect our thought processes, and is often referred to as the ‘Sapir-Whorf hypothesis’, after the two linguists who brought the idea into the spotlight. Whorf writes how “Language is not merely a reproducing instrument for voicing ideas but rather is itself the shaper of ideas, the program and guide for the individual’s mental activity” (1956:212), and I will explain how it is able to do so. In this essay I will argue that certain

In 1783, an amateur astronomer named John Michell theorized that if an object had a radius that was five hundred times larger than the sun, but with the approximate average density of the sun, the velocity that would be required to escape the object’s gravitational pull would be faster than the speed of light (Temming). Simon Pierre Laplace, a French astronomer and mathematician, came to a similar conclusion a few years later (Temming). However, their findings were largely discredited since Michell

No matter when we consider the beginning of time, there will always be the question of origin. "And before then- what?" The origin of the universe remains a mystery, but extrapolation from current working models can be used to speculate about the universe 's early development. The leading theory on the early development of the universe is the Big Bang theory, which puts forth the idea that the universe expanded from a singularity, or a single point.[1] The Big Bang laid the seeds that lead to the

like the familiar asys of forced relativity where c was assumed a universal constant and alien c and parochial c became equal. This comparison makes it obvious that the unusual results of forced relativity are not caused by motion, but by changing the asys. Therefore, by principium axioma, the strange results of special relativity are only applicable in the mathematical

Motion and time are fundamental components of life. Finding himself late to work, an employee will drive faster, which in turn, will reduce the time needed to commute to his job. The rules of motion and time are known intrinsically to every person on the planet. As children, these “Laws” become common sense. No explanation is needed when a sleeping student falls out of his desk onto the floor. Motion and time were always considered to be self-explanatory and obvious parts of everyday

Einstein’s Theory of General Relativity originally came to him in 1907 while he was sitting in a chair in the patent office in Bern. Lost in thought, he began wondering what it would be like to drop a ball while falling off the side of a building (James Overdunn, Stanford Edu) Granting all this, he realized that the person who was falling would not be able to detect the effect of gravity on the ball whereas an observer could. Hence, he figured out the principle of Equivalence, that gravity pulling

at forty miles per hour relative to the ground. If you were to throw a ball out of the car in front of you at five miles per hour relative to you, the ball would be traveling at forty five miles per hour relative to the ground. This is Galilean relativity and, until Einstein, was believed to be an

In order to explain the effects of gravity we must begin by explaining what causes the phenomenon. Objects with mass warp space time. The idea that space and time possess the ability to be curved or warped is recent. Before, the axioms of Euclidean geometry were considered to be true. One of the consequences of these axioms is that the angles of a triangle add up to 180°. Considering for example, the surface of the Earth. The closest thing to a straight line we have is a curve. These are the shortest
