| 1357140 | 2004-07-31 23:28:00 | No Vince, zero point energy was first postulated to explain the discrepancy between classical mechanics and quantum mechanics when considering the vibrational energy of an oscillator. It can also be postulated in a general way by considerations of the uncertainty principle. It isnt the energy of "pure vacuum", it is the vibrational energy possessed by molecules/atoms at absolute zero. I think conventional semi conductors would have a problem at absolute zero, though their leads would be superconducting, and electron noise would be low, but as I hinted my solid state physics/quantum physics and what I remember well over 40 years old now and out of date :) |

The California Institute for Physics and Astropysics says "It is the lowest state of otherwise empty space". www.calphysics.org Doing a Google for Zero Point Energy gave about 2,950,000 results.

| 1357144 | 2004-08-01 07:09:00 | Well I have done some problem solving on this one,...remember I hadn't plugged in a speaker so on doing this I got some beeps. Mainly refer to a ram problem....well it does the same beeping even when I take the ram out so it isn't detecting it. Whether it is the ram or motherboard I am not sure,...least it is still all under warranty its easy to get fixed. Cheers for all your insight into this one. Definately gave me something to look into. |

| 1357145 | 2004-08-01 07:21:00 | The beeps from the bios go through the little speaker inside the PC not the external speakers. | mikebartnz (21) | ||
| 1357146 | 2004-08-01 09:11:00 | Ah well, that's progress for you Vince. Zero point energy, not so much re-defined as extended to wider considerations, from the micro to the macro. :) Perhaps I should go back to school. |
