Extreme overclocking involves cooling a CPU to subzero temperatures using an air conditioner, dry ice or liquid nitrogen. This causes the surrounding air to cool down, forming droplets on the CPU, motherboard and heat sink. Overclockers prevent droplets from accumulating on the motherboard using petroleum jelly or some sort of absorbent insulating material.

Since this condensation comes from the air, I figure it should be free of impurities, just like distilled water. This should mean that the droplets shouldn't be able to cause a short circuit. Due to the low temperature, corrosion shouldn't be a problem either.

Am I missing something here?

The title says it all, have any of you found a book on D-branes worth recommending?

All blades have the same size, 36cm long, aerodynamically well shaped. But. The first weighs 120g, the second 125g… And the third one 210g… This is a small problem. So what are my options now? Making a new blade would be the last option, but do I have any other options?

Physicist Ranga Dias and his colleagues have twice claimed to make a room-temperature superconductor. But many researchers question the evidence.

The 2023 Nobel Prize in Physics is awarded to Pierre Agostini, Ferenc Krausz and Anne L'Huillier for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter

  • Summary

Since the discovery of antimatter decades ago, particle physicists have wondered if these particles were repulsed by gravity. Einstein predicted that despite having opposite charges to its regular matter counterparts, antimatter should still behave like matter does concerning gravity. This has been tricky to confirm experimentally since it's hard to make enough antimatter to observe its behavior. Particle physicists have finally pulled it off, using the ALPHA-g experiment at CERN, generating antihydrogen atoms and then dropping them in a 3-meter tall vertical shaft.
