Students were also advised to take their own notes. No single text will be used for main material, but some exercises and later material will be taken from "Introducing Einstein's Relativity" , by Ray d'Inverno (Oxford). Quick link to schedule, notes and exercises! Course Description This course is about space, time and gravity. The fundamental idea of Einstein's theory of General Relativity is that the phenomena we call gravitational are actually geometrical properties of spacetime: Gravity is the geometry of spacetime . We shall therefore spend a lot of our time concerned with understanding how to describe spacetime, and its geometry. We shall take a very different route from that which is normally taken in learning about gravitation: We will not emphasize too early the powerful mathematical formalism of tensor analysis, relying instead on simple physical intuition, encountering useful mathematics as we go along. All of the physics presented in the course can be appreciated with just some simple differential and integral calculus, algebra, and common sense. If you have done a good basic Classical Mechanics course using these, you will be in good shape....if you have done an electromagnetism course at a similar level, you will be more than prepared.

An easy primer by the world's most famous living physicist By STEPHEN HAWKING Person of the Century: Albert Einstein J. Madeleine Nash: Einstein's Unfinished Symphony Roger Rosenblatt: The Age of Einstein TIME's Choice: Runner-Up: Franklin Delano Roosevelt Runner-Up: Mohandas Gandhi The Necessary Evil? Why Hitler Is Not Person of the Century Monday, Jan. 3, 2000 Toward the end of the 19th century scientists believed they were close to a complete description of the universe. They imagined that space was filled everywhere by a continuous medium called the ether. Light rays and radio signals were waves in this ether just as sound is pressure waves in air. All that was needed to complete the theory was careful measurements of the elastic properties of the ether; once they had those nailed down, everything else would fall into place. Soon, however, discrepancies with the idea of an all-pervading ether began to appear. You would expect light to travel at a fixed speed through the ether. So if you were traveling in the same direction as the light, you would expect that its speed would appear to be lower, and if you were traveling in the opposite direction to the light, that its speed would appear to be higher. Yet a series of experiments failed to find any evidence for differences in speed due to motion through the ether. The most careful and accurate of these experiments was carried out by Albert Michelson and Edward Morley at the Case Institute in Cleveland, Ohio, in 1887. They compared the speed of light in two beams at right angles to each other. As the earth rotates on its axis and orbits the sun, they reasoned, it will move through the ether, and the speed of light in these two beams should diverge. But Michelson and Morley found no daily or yearly differences between the two beams of light. It was as if light always traveled at the same speed relative to you, no matter how you were moving.

Ricci A Mathematica package for doing tensor calculations in differential geometry Version 1.37 Last Updated November 12, 2002 Ricci is a Mathematica package for doing symbolic tensor computations that arise in differential geometry. It has the following features and capabilities: Manipulation of tensor expressions with and without indices Implicit use of the Einstein summation convention Correct manipulation of dummy indices Display of results in mathematical notation, with upper and lower indices Automatic calculation of covariant derivatives Automatic application of tensor symmetries Riemannian metrics and curvatures Differential forms Any number of vector bundles with user-defined characteristics Names of indices indicate which bundles they refer to Complex bundles and tensors Conjugation indicated by barred indices Connections with and without torsion Limitations: Ricci currently does not support computation of explicit values for tensor components in coordinates, or derivatives of tensors depending on parameters (as in geometric evolution equations or calculus of variations), although support for these is planned for a future release. Ricci also has no explicit support for general relativity, or for other mathematical physics or engineering applications, and none is planned. If you are interested in such support, I recommend that you consider the commercial package MathTensor, which is far more extensive than Ricci, and provides all these capabilities and more.

132. Albert Einstein And The Theory Of Relativity Albert Einstein and the Theory of relativity. Albert Einstein 18791955. Einstein Albert s Turn to Kick Butt. We shall consider relativity in more detail later. http://csep10.phys.utk.edu/astr161/lect/history/einstein.html

Albert Einstein and the Theory of Relativity Albert Einstein Newton's theory of gravitation was soon accepted without question, and it remained unquestioned until the beginning of this century. Then Albert Einstein shook the foundations of physics with the introduction of his Special Theory of Relativity in 1905, and his General Theory of Relativity in 1915 (Here is an example of a thought experiment in special relativity ). The first showed that Newton's Three Laws of Motion were only approximately correct, breaking down when velocities approached that of light. The second showed that Newton's Law of Gravitation was also only approximately correct, breaking down in the presence of very strong gravitational fields. Newton vs. Einstein: Albert's Turn to Kick Butt We shall consider Relativity in more detail later . Here, we only summarize the differences between Newton's theory of gravitation and the theory of gravitation implied by the General Theory of Relativity. They make essentially identical predictions as long as the strength of the gravitational field is weak, which is our usual experience. However, there are three crucial predictions where the two theories diverge, and thus can be tested with careful experiments. The orientation of Mercury's orbit is found to precess in space over time, as indicated in the adjacent figure (the magnitude of the effect is greatly exaggerated in this figure). This is commonly called the "precession of the perihelion", because it causes the position of the perihelion to move. Only part of this can be accounted for by perturbations in Newton's theory. There is an extra 43 seconds of arc per century in this precession that is predicted by the Theory of General Relativity and observed to occur (a second of arc is 1/3600 of an angular degree). This effect is extremely small, but the measurements are very precise and can detect such small effects very well.

It was a subject of intense interest in the 1960’s and 1970’s when advances included the discovery of the Kerr solution, the study of black holes and singularity theorems and the introduction of asymptopia as a framework for studying asymptotic properties, including gravitational radiation. At the same time there were many mathematical problems which resisted mathematical analysis. In recent years there have been significant advances in our understanding of the topological, geometrical and PDE aspects of general relativity and progress is once again becoming rapid. New results are being obtained, and older results re-proved in greater generality. This programme will be structured around four themes: Elliptic aspects of general relativity: new methods of solving the constraint equations, developments from the solution of the Riemannian Penrose inequality, the study of static and stationary solutions including black holes.

Gravitation and the General Theory of Relativity As we have discussed in an earlier section , the theoretical physicist Albert Einstein introduced his Special Theory of Relativity in 1905 and his General Theory of Relativity in 1915. The first showed that Newton's Three Laws of Motion were only approximately correct, breaking down when velocities approached that of light. The second showed that Newton's Law of Gravitation was also only approximately correct, breaking down when gravitation becames very strong. Special Relativity Einstein's Special Theory of Relativity is valid for systems that are not accelerating. Since from Newton's second law an acceleration implies a force, special relativity is valid only when no forces act. Thus, it cannot be used generally when there is a gravitational field present (as we shall see below in conjunction with the Principle of Equivalence, it can be used over a sufficiently localized region of spacetime). We have already discussed some of the important implications of the Special Theory of Relativity. For example, the most famous is probably the relationship between mass and energy . Other striking consequences are associated with the dependence of space and time on velocity: at speeds near that of light, space itself becomes contracted in the direction of motion and the passage of time slows. Although these seem bizarre ideas (because our everyday experience typically does not include speeds near that of light), many experiments indicate that the Special Theory of Relativity is correct and our "common sense" (and Newton's laws) are incorrect near the speed of light.
