Extractions: Welcome aboard C-ship , exploring flight near the speed of light! C-ship helps you understand Einstein's theory of Special Relativity intuitively through the medium of computer-synthesised images. To view the images in this document, you need a graphics-oriented Web browser. We'll be looking at lots of pictures on our journey. Sending large pictures across the Internet consumes precious network bandwidth and can take a long time. So, I'll show small "thumbnail" views of most pictures, with words "GIF" and "JPEG" beneath the image. When you click on the word, you'll see the full-size image. Most of the images are understandable from the thumbnail views. It's up to you which images you'd like to examine in more detail. If your browser supports in-line JPEG images, click on JPEG, otherwise use GIF. JPEG images look much better and take much less time to transmit to your computer, but not all Web browsers understand them. by John Walker

Extractions: Newtonian mechanics and special relativity for students with good preparation in physics and mathematics at the level of the advanced placement curriculum. Topics include an introduction to Lagrangian mechanics, Noether's theorem, special relativity, collisions and scattering, rotational motion, angular momentum, torque, the moment of inertia tensor, oscillators damped and driven, gravitation, planetary motion, and an introduction to cosmology. I am delighted to say that you all did well in the course. I know that a few of you were disappointed that your brains froze up on the inclass final. I wish I knew how prevent this. But none of you did badly, and remember that I know many of you well and I am happy to tell others about your strengths. If you would like to discuss spring term courses, I would be happy to talk to you. I am hoping to be in the department in the late afternoons. There will be construction going on near my office this term, so I probably won't spend time there until about 2:30pm. I will also be available in the Leverett dining hall at various time. Send an email if you can't find me.

Extractions: 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.

Extractions: Forward Back Up Map ... Information Einstein's first theory of relativity, which he published in 1905, broke away from the Newtonian reliance on space and time as immutable frames of reference. This theory was immediately recognized by the scientific community as having profound implications for physics and cosmology. Einstein's main goal was to address the apparent inconsistencies in Maxwell's electromagnetic theory. No wonder Einstein named his paper The Electrodynamics of Moving Bodies Einstein's 1905 paper Later to become known as the Special Theory of Relativity , its first postulate was that the speed of light is the same for all observers, regardless of their motion relative to the source of the light. The second postulate was that all observers moving at constant speed should observe the same physical laws. Putting these two ideas together, Einstein showed that the only way this can happen is if time intervals and/or lengths change according to the speed of the system relative to the observer's frame of reference. This flies against our everyday experience but has since been demonstrated to hold in a number of very solid experiments. For example, scientists have shown that an atomic clock travelling at high speed in a jet plane ticks more slowly than its stationary counterpart.

Extractions: Special Relativity Back to Frequently Asked Astronomy and Physics Questions Can you give me information on why travelling at light speed is so impossible? DS, 8th grade, Blacksburg Middle School, Blacksburg, Virginia, USA. 1996 Is there a chance that we may be able to go the speed of light sometime in the future? DS, 8th grade, Blacksburg Middle School, Blacksburg, Virginia, USA. 1996 Einstein said that if something could travel at light speed its mass would duplicate. How could it be? JLR, UAM, Mexico City, Mexico. 1997 Please explain how the Twin Paradox works. Now, every space ship, or other plane, etc., has traveled at a speed very small compared to light, so you might be wondering how we know the Special Relativity Theory is correct (why should we believe it without evidence?). Although, we have never made any large object (like a space ship) travel at a considerable fraction of light speed, experimental particle physicists are constantly making electrons and the like travel at speeds like 99% of the speed of light in particle accelerators. These accelerators only work properly because they are constructed obeying the laws of Special Relativity. To make the electrons accelerate, when they are already at 90% of the speed of light, does indeed take quite a bit more energy than would a comparable speed change when they are only moving at 10% of the speed of light. Special Relativity theory appears correct, in detail, even under the extreme speed conditions of a particle accelerator.

Seven Dimensional (and Up) Einsteinian Hyperspherical Universe
Updated material from the archived Cosmology Review site written in cooperation with UNC. A conceptualization in plain English of an eternal, dual, periodic universe model according to special and General relativity.

Extractions: by Samuel A. Cox, BS; MSEd. Where are those one or two orders of magnitude of mass necessary to give us the universe we observe? Why is the universe accelerating outward? Why is the early universe observed to be dominated by Black Holes? How is order created, conserved and preserved in the cosmos? Why can matter only exist on a microscopic singular foundation? These and many, many other observations and questions are answered by this quasi-static "Geometric Universe" model, in which the dimensional parameters of cosmology are logically adjusted to better fit the mathematical dualism of General Relativity. This site consists of descriptive material and informal, non technical discussion of the profound implications of Singularity, Duality and Periodicity in a General Relativity Cosmology Model based on ... hyperspherical space with seven large dimensions; two/ sphere, Schwarzschild geometry and a single process but periodic time dimension. The model features a discrete, massive quantum Planck Realm, dual 3-space "hemispheres" with submicroscopic, and macroscopic, (astronomical) singular/photonic antipodes, inverse mapping with cosmological time separation, a photon based frame of reference system- and "time reversal" without an inverse process!

Extractions: Next: The Galilean Transformations STR - The Special Theory of Relativity Let's briefly recapitulate the situation in 1865: the Maxwell equations , which correctly described all the phenomena of electromagnetism known in the mid-19 th Century (and then some), predicted also that electromagnetic fields should satisfy the wave equation by virtue of a changing creating and vice versa , the electric and magnetic fields would be able to ``play off each other" and propagate through space in the form of a wave with all the properties of light (or its manifestations in shorter and longer wavelengths, which we also term ``light" when discussing electromagnetic waves in general). Fine, so far. But there are some unsettling implications of this ``final" explanation of light. First of all (and the focus of this handout) is the omission of any reference to a medium that does the ``wiggling" as the electromagnetic wave goes through it. Water waves propagate through water, sound waves through air, liquid or solid, plasma waves through plasmas, This was the first time anyone had ever postulated a wave that just propagated by itself through empty vacuum (or ``free space," as it is often called in this context). Moreover, the propagation velocity of light (or any electromagnetic wave) through the vacuum is given unambiguously by the
