The homework problem sets are not optional. You are encouraged to discuss the class material and homework problems with your classmates and to work in groups, but all submitted problems should represent your own work and understanding.

The final exam will be held in Nat. Annex and will cover the complete course material. You must take the final exam to pass the course. Links to the Website of the Textbook Webpage of Cheng's textbook Please make sure you have the second printing of the second edition of the textbook, since many significant typographical errors have been corrected.

If you have the first printing of the second edition, please consult the webpage of Cheng's textbook for the relevant errata. The most recent compilation of the errata to the reprinting of the second edition of the textbook has also been posted to the webpage of Cheng's textbook.

Other Class Handouts 1. By Clifford M. Will Florida U. Mar 28, Published in Living Rev. By Emanuele Berti Mississippi U. Jan 28, Published in Class. A handout entitled The velocity and momentum four-vectors examines the properties of the velocity and momentum four-vectors of special relativity, and provides a careful derivation of the relativistic law of addition of velocities.

In addition, an appendix provides a derivation of the most general Lorentz boost matrix. A handout entitled How do the connection coefficients transform under a general coordinate transformation? The transformation law contains an inhomogeneous piece, which implies that the connection coefficients are not the components of a tensor. Nevertheless, this inhomogeneous piece is critical in establishing two results. First, the connection coefficients vanish in the local inertial frame. Second, presence of the connection in the definition of the covariant derivative is precisely what is needed so that the covariant derivative of a tensor is also a tensor.

A handout entitled Parallel Transport and Curvature presents the details of the calculation that demonstrates the connection no pun intended! The derivation presented is slightly more general than the one given in Box A handout entitled The Cosmological Constant Problem discusses some of the implications of adding a cosmological constant to Einstein's field equations of general relativity. In particular, the handout describes the worst prediction in the history of physics.

The predicted value of the vacuum energy density due to quantum fluctuations is a factor of 10 larger than the observed value. Moreover, if an additional contribution to the vacuum energy exists to cancel off the contribution of quantum fluctuations, the cancellation must be unimaginably precise accurate to significant figures.

This is one of the greatest unsolved problems of fundamental physics. Astrophysical constants and parameters.

Many regard Albert Einstein as the greatest physicist since Newton. What exactly did he do that is so important in physics? We provide an introduction to his physics at a level accessible to an undergraduate physics student. All equations are worked out in detail from the beginning. Einstein's doctoral thesis and his Brownian motion paper were decisive contributions to our understanding of matter as composed of molecules and atoms. Einstein was one of the founding fathers of quantum theory: his photon proposal through the investigation of blackbody radiation, his quantum theory of photoelectric effect and specific heat, his calculation of radiation fluctuation giving the first statement of wave-particle duality, his introduction of probability in the description of quantum radiative transitions, and finally the quantum statistics and Bose-Einstein condensation. Einstein's geometric theory of gravity, general relativity, extends Newton's theory to time-dependent and strong gravitational fields.

Don't have an account? In the weak-field limit Einstein's equation can be linearized and it takes on form of the familiar wave equation. Gravitational waves may be viewed as ripples of curvature propagating in a background of flat spacetime. The strategy of detecting such tidal forces by a gravitational wave interferometer is outlined. The rate of energy loss due to the quadrupole radiation by a circulating binary system is calculated, and found in excellent agreement with the observed orbit decay rate of the Hulse-Taylor binary pulsar.

Einstein's general theory of relativity is introduced in this advanced undergraduate and beginning graduate level textbook. Topics include special relativity, the principle of equivalence, Riemannian geometry and tensor analysis, Einstein field equation, as well as many modern cosmological subjects: from primordial inflation, cosmic microwave anisotropy to the dark energy that propels an accelerating universe. The subjects are presented with an emphasis on physical examples and simple applications. One first learns how to describe curved spacetime. At this mathematically more accessible level,

*Collier, General Relativity is a theory of gravity and is necessary to understand recent advances at the forefront physics research, including black hole physics, the early universe, string theory, high energy physics and astrophysics. The discovery of gravitational waves was recently recognized by the awarding of the Nobel prize in physics.*
