Einstein became an overnight celebrity‚ thanks to a solar eclipse. An experiment had confirmed that light rays from distant stars were deflected by the gravity of the sun in just the amount he had predicted in his theory of gravity‚ General Relativity. General Relativity was the first major new theory of gravity since Isaac Newton’s‚ more than two hundred and fifty years earlier. Einstein became a hero‚ and the myth building began. Headlines appeared in newspapers all over the world. On November 8

of the inconsistencies in the current model of mechanics and electromagnetism with special relativity. Rather than attempting to remold Maxwell’s equations‚ Einstein‚ in 1905‚ rejected prevailing assumptions about the nature of time and space in the reference frames of observers with different velocities: instead of forcing the time and spatial position of an object to be invariant‚

Why does it matter that language may be sexist‚ racist and so on? Apart from the obvious point that such language is offensive‚ many people that the language we hear and use has a big influence on the way we think. There are two extreme views of this issue‚ the universalist and the relativist. The universalist position is that all humans share common ways of thinking‚ a set of basic concepts about the world which we may call conceptual primes. One example is relative distance‚ the distinction between

The History of Classical Gravitational Theory and General Relativity In the beginning scientists and religious men of their era tried to explain the universe both biblically and scientifically. One of the foremost Greek scientists was Aristotle; taught by Plato‚ that the circle and sphere are the two most perfect shapes in a 2 and 3 dimensional universe‚ Aristotelian system placed Earth at the center of the universe; and all other heavenly bodies revolved around the earth in crystalline orbitals

Wormholes and Interstellar Travel: An Application of General Relativity In Einstein’s theory of general relativity‚ time and space are made dynamic and are curved by matter and energy. This has allowed physicists to dream up configurations that would allow travel to far distant places in the universe that were once made unattainable by the sheer distances and the natural speed limit of the universe; the speed of light. The theory has also opened up the possibility to travel through time. Like

Physics is a natural science that involves the study of matter and its motion through spacetime‚ as well as all related concepts‚ including energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics had been considered synonymous with philosophy‚ chemistry‚ and certain branches of mathematics and biology

size on diffusion phenomena. Theory of relativity and E = mc² Einstein’s "Zur Elektrodynamik bewegter Körper" ("On the Electrodynamics of Moving Bodies") was received on 30 June 1905 and published 26 September of that same year. It reconciles Maxwell’s equations for electricity and magnetism with the laws of mechanics‚ by introducing major changes to mechanics close to the speed of light. This later became known as Einstein’s special theory of relativity. Consequences of this include the time-space

existing things exist”1. While this view is coherent with Newton’s theory of spacetime‚ it faces some challenges when combined with the Theory of Special relativity (STR). In this essay‚ I will first articulate more specifically the thesis of presentism and show the main arguments of the opposite position known as eternalism. I will then outline the special theory and its consequences for the metaphysics of presentism. I will consider some of the problems that presentism faces in the relativistic context

Generally speaking‚ students with special needs benefit from integration into general education classrooms when it is handled appropriately; however in many cases‚ students are still being short-changed. Integrating students with special needs into a general education classroom has many advantages‚ both social and academic. For example‚ all students are required to receive and be tested
