82. SimScience - An Introduction To Simplicial Quantum Gravity Contains introductory material on quantum mechanics and relativity and outlines one method of combining the two theories. http://www.simscience.org/membranes/advanced/essay/quantum_grav1.html

An introduction to simplicial quantum gravity About three hundred years ago Isaac Newton wrote down rules describing the mechanics of moving objects. He also described gravity as a force that pulls massive objects together. Isaac Newton (1642-1727) We know today that Newtonian physics is really only an approximation that works well in almost every situation that we encounter in everyday life. We can use these rules to describe exactly how a baseball will travel when thrown. We know how to use Newton's laws so well that we can launch a rocket, and give it exactly the right amount of thrust so that it can coast to Jupiter, a planet only 90,000 miles across, but millions of miles distant from earth and orbiting at 30,000 miles per hour. This approximation is not good enough in some situations. If I want to describe the behavior of things on a very small scale, such as the motion of an electron around an atom, I cannot use the same Newtonian rules that I use to describe the motion of a baseball thrown across the infield. For really small-scale physics, I must use a new set of rules proposed in the early 1900's. These rules are called quantum mechanics There is another situation when Newtonian mechanics is not good enough. That is when we want to describe the motion of objects near very large masses like stars and whole galaxies. In these situations we must use another theory developed in the early 1900's, Albert Einstein's

TO UNDERSTAND RELATIVITY You are travelling in a rocket at 200,000 km/sec, and you send, in your movement's direction, a projectile that, seen from the earth, propagates at 250,000 km/sec. Does it mean that, if you measure the speed of the projectile from the rocket, your measures will give 50,000 km/sec? It's not sure at all. To calculate the speed of the projectile, that is the distance covered by unit of time, you will have to use some instruments to measure the distance (a ruler) and the time (a clock). Let's take a simple clock, made of a light ray going on and back between two mirrors, distant of 1.5 meter. One second corresponds to 100,000,000 rebounds. You install this clock in the rocket so that the light ray propagates perpendicularly to the rocket's trajectory. For the ruler, it's a little more complicate, since the projectile moves outside the rocket. You find the following solution: before sending the projectile, you send a mirror (M) provided with a small motor before the rocket. You follow the progression of the mirror with the help of a light signal. When the signal will take 1/3 second to go to the mirror and come back, you will know that the mirror will be at 50,000 km. 1/6 of second before this moment, you send a signal starting the motor of the mirror in order to stop it (we suppose the motor reacts instantaneously). Then you control that the mirror remains stationary at this distance.

Foundation Physics: Preface: This work is based on an elementary particle, termed the 'P-Particle', which is first postulated to be the fundamental constituent of all matter present in the universe. The particle is defined by several axioms and can be regarded as being the quantum of matter. Just as energy is quantised, and energy and mass are interchangeable, then on this basis the idea of mass being quantised is first assumed and subsequently verified. It is subsequently shown that this particle can be identified with the neutrino. From this model, a large number of results are derived which potentially shed a new light on aspects of physics ranging from classical Newtonian mechanics and relativity to quantum mechanics and particle physics. Amongst the topics included are: Solutions to the Einstein-Friedmann equations A detailed evaluation of Schwartzchild and rotating black holes The expansion of the universe and its nature Dark matter The nature of light Background radiation and its origin Bijan Yavari In order to view the following you may need to install adobe acrobat reader which you may obtain from here Foundation Physics - Part 1 Foundation Physics - Part 2 Foundation Physics - Part 3

The Learning Objectives and references are in the Self-Paced Study Guide Essay on the General Theory of Relativity by John L. Safko A. General Principle of Covariance (or Only the Tides are Real) Consider yourself in an elevator. You cannot see outside, so you must determine the nature of the surrounding universe by local experiments. You let go of a coin and it falls to the bottom of the elevator. Aha!, you say, I am at rest on Earth. But, you could be in a spaceship that is accelerating and far from any other object. This is shown in Fig. 57-1. Fig. 57-1: Locally being at rest on the Earth's surface is equivalent to being in a uniformly accelerated spaceship. Consider the opposite case. You float from the floor and the coin does not fall when you release it. Aha!, you say again, I am in space far from any other body. But, you could be freely falling towards the Earth as shown in Fig. 57-2. Fig. 57-2:

And what will ultimately become of it? These are two fundamental questions which have long interested humankind. In the more than 70 years since the discovery that that the Universe is expanding, we have made some significant steps in understanding how the Universe began and how it must have evolved to be what it is today. We know this: galaxies and clusters of galaxies formed from tiny fluctuations in the early Universe. We can measure these fluctuations by mapping the cosmic background radiation and relate them to the structures which we observe today. However, many challenges remain such as: What is the Age of the Universe? - or - How Fast is the Universe Expanding? In the 1920s

Particles, Special Relativity and Quantum Mechanics Special Relativistic Paradoxes and Puzzles Tachyons The Particle Zoo Does Antimatter Fall Up or Down? ... Main Physics Contents page Special Relativistic Paradoxes The Barn and the Pole The Twin Paradox The Superluminal Scissors Relativity and Quantum Mechanics Contents The Barn and the Pole Updated 4-AUG-1992 by SIC Original by Robert Firth Paradoxes Contents These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer. You are that observer, sitting on the barn roof. You see the pole coming towards you, and it has contracted to a bit less than 40m. So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed. But consider the problem from the point of view of the runner. She will regard the pole as stationary, and the barn as approaching at high speed. In this reference frame, the pole is still 80m long, and the barn is less than 20 meters long. Surely the runner is in trouble if the doors close while she is inside. The pole is sure to get caught.
