| Question about how steel beams fail | 30 Jul 2008 23:09 GMT | 1 |
Suppose you were pounding a steel beam into the ground with a pile driver. After you had driven the beam say five feet into the ground, you then arranged to hit the top of the beam with a weight far heavier

| Big Bang Energy Buildup | 30 Jul 2008 22:24 GMT | 3 |
The Dark Energy of the universe started at zero and built up. It was then concentrated into neutrons on the inflated hypersphere surface of which also started at zero or time zero. These neutrons decayed into protons neutrons neutrinos and incidental radiation that we now call

| Gyroscope | 30 Jul 2008 20:41 GMT | 13 |
In a famous experiment in the Christmas lectures in London Prof Eric Laithwaite had a small boy lift a huge gyroscope when not spinning. the boy could hardly lift it. He then set it spinning and the boy could lift it easily. Now when you push on a gyro it precesses and

| Space's Time | 30 Jul 2008 20:03 GMT | 4 |
Two times: one for space(gravity) the other for matter in that space. Space's time pushes light. Matter's time is always slower than space's time becuase it moves and there is the transverse Doppler. Mitch Raemsch

| New Technology for Energy Independence... | 30 Jul 2008 19:15 GMT | 3 |
What with the high price of gasoline and the energy crisis, clearly new technology is needed to save the planet. Luckily many smart people are thinking about these problems and have developed new technology to save the earth. One example is seen below:

| Does Relativity generate more heat than light? | 30 Jul 2008 17:36 GMT | 123 |
I suggest that if anyone wants to analysis the utility of the various physical models, that they take a look around and note what models are used every day to make life better for mankind.

| Which is the strongest structure : Honeycomb or Arch? | 30 Jul 2008 09:09 GMT | 22 |
Strongest structure for say a bridge where the force is mostly downwards. I've heard the honeycomb is the strongest structure in nature. Bees have evolved to use it over millions of years when building their
