"The Right Angle Lever Paradox"
    The "Right Angle Lever Paradox" is a classic construct which is taught
in most courses in Special Relativity. As with all paradoxes, it reveals
that and error has been made in our thinking. It may be interesting then to

I found this quote by Noam Chomsky, that's quite thought provoking:
______________
If you go back to the Bible, there's a category of people who were
called prophets, a translation of an obscure word, they were

Relativity - Affine Geometry ?
Abstract:
Einstein addressed the twin paradox in special relativity in a relatively
unknown, unusual and rarely cited paper written in 1918, in the form of a

Physics has a lot to say about why and how apples fall from trees. It's
quite common to see apples drawn in physics texts - often on the cover.
Much importance seems to be attached to them.
But I haven't managed to find any physics texts that have much to say

This is a Hypergeometrical Universe take on those problems.  Hund's law
is presented in terms of minimizing four-dimensional volume during the
trajectory of the Fat Electron.
Superconductivity goes one step further and consider the subsequent

Please bear with me again. Consider a spaceship with two people at
front and back ends. The person at the front resets his clock and sends
a light signal to the person at the back, who resets his clock when he
receives the signal. Then, they both move to the center of the ship to

Inverse sound waves cancel each other out, so why can't there be a
gravity equivalent?

Quantum Pyramid
The Quantum Pyramid is another powerful aspect of our philosophy.  The
understanding of the pyramid combined with our method of reproducing
this effect has led us to the realization that we create our own

Once the tyrranosaur was alive and the tooth-set dead.
Now the tables are turned.  The teeth live the tyrant's remnants from

Faster than Light?
The theory of relativity claims that the motion of physical objects
cannot exceed a speed of 300,000km/sec. However, we know from
experience (e.g. equatorial rocket launchings, multistage rocket

Past, present and future of E=mc2:  A  CRITICAL DISCUSSION
The link with detailed discussion
(i) How and When E=mc2 was derived ?

Have heard it asserted Einstein's discovery's of special and general
relativity were made through purely
rational means, ie mostly through his famous "thought" experiments and
such. Am looking for a concise summary of how true such a viewpoint is,

If you were in a spaceship with absolutely nothing in your visual range, and
another identical spaceship moving in a straight line flew passed you, SR
tells us that it would be impossible to know who's moving and who's
stationary.  But wouldn't measuring the mass of both ...
