I was thinking whether I should put this threat under general physics or engineering... but anyway, here's the problem: how long do we need to wait until quantum computing is put to use?
Also, can programmes that run on classical computers run on quantum computers, or do they need an entirely...
Hey guys just did some algebraic calculation and got a strange conclusion.
since speed of sound is related to speed of molecule, we can assume they are proportional to each others. Then, according to kinetic theory equation,
pV = 1/3 NMc ...(1)
where c is the rms speed of air molecules...
I suppose it is due to electrostatic force. When writing on the blackboard, there is charge induced by friction on the chalk powder, thereby sticking to the metallic blackboard.
But this is just a conjecture. Maybe you can (dis)prove it by experiments using a Van de Graaff generator?
Hi there,
I'm also very interested in the mechanism of blu-tack.
I don't really understand why hydrocarbon polymers are adhesive. From my chemistry knowledge, hydrocarbon polymers are supposed to be non-polar, leave alone forming hydrogen bonds. Their nature should be like oil - slippery...
