| Einstein Who? | 23 Nov 2008 11:53 GMT | 67 |
A. Zeynel at sci.physics.research asked the following. "if Einstein came back to Earth he would not recognize his theory and he would be told to study MTW if he wanted to learn General Relativity."

Let's suppose we have infinite space and infinite amount of time. Space is initially filled with randomly distributed matter and antimatter. Average density of matter might be similar to what we observe in galactic arms.

| damaging circuits with ???? | 23 Nov 2008 11:27 GMT | 33 |
is it possible to damage a transformer, transistor, capasitor or resistor using some form of conduction,convection or radiation device? the device was off when it was damaged and totally seal ( humidity or any natural external cause are not a posibility)

| sonoluminescence: sonofusion explained | 23 Nov 2008 10:38 GMT | 15 |
The first to accomplish Sonofusion has to be the Pistol shrimp. In 1874 John W. Keely described and demonstrated the acoustic dissociation of water. In 1970, Dr. Andrija Puharich (MD) acidentally made oxyhydrogen gas

| Relatvity of Simultaneity Revisited | 23 Nov 2008 07:09 GMT | 5 |
In Enistein's train gedanken to illustrate the SR concept of relativity of simultaniety (RoS) he specified that when the train observer and the track observer are coincide with each other two lighting strikes occur at the ends of the train simultaneously for the

| What does a clock measure ? | 23 Nov 2008 05:23 GMT | 102 |
The gravitational field of the Earth adds about a million part to clock slowing, or time dilation. Generally, this is accepted as some Newtonian view of time, that is deformed by the presence of the gravitation of nearby mass, in this

Is there a talk.physics newsgroup? My NNTP server does not list one, though I would think a moderated physics newsgroup woulod already exist. I have an interest in physics, and trying to pick the non-kook articles out of the much, much larger kook articles

| Counterintuitivity | 23 Nov 2008 04:45 GMT | 332 |
The so-called 'counterintuitive' is a severely problematic feature in modern physics. It can be used, merely on the prompting of some mathematical formula, without the application of any other principle that might control and

If two perfectly spherical balls have the same diameter and surface smoothness, but are of different weights, when they are dropped they will have the same air resistance as they fall. If such balls are dropped from an identical height, and both subsequently impact the

| Gravity and mass-energy equivalence | 22 Nov 2008 21:04 GMT | 9 |
According to Einstein's theories of relativity, mass and energy are equivalent. So when you add energy, you also add mass, and vice versa. This would imply that a spring compressed is slightly heavier than one not compressed, for example (although too small to measure).

| Energy doesn't exist, it's an imaginary soothsaying construct | 22 Nov 2008 20:55 GMT | 13 |
Energy tries to describe events that didn't take place jet. When the event does take place the energy goes some place else. If I have 2 marbles and 1 hole the size of 1 marble one could argue the marbles both have gravitational potential energy.
