as I'm experiencing what appears to be a completely sleepless night, I've fallen back on my old staple of a huge bowl of Sugarpuffs, ice-cold milk and some of my wife's Quantum theory books (she's fascinated by this stuff)

heres a wee snippet to get your head around -

Helium - at room temperature you can breathe it and speak in a squeaky voice, or fill balloons to float, etc
but cool it down to below 2 Kelvin its becomes a superfluid ruled by quantum physics - its a liquid that runs uphill and climbs walls! it also has no friction - put the superfluid helium in a bowl and start the bowl spinning - the liquid remains stationary while the bowl revolves around it!!
Now set the liquid in motion and leave the bowl still - the helium will continue revolving for ever - it'll never, ever stop!!  completely frictionless - utterly amazing

Another fascinating fact that to me proves there is a very universally huge amount of knowledge that Homo sapien sapien has just nibbled at so far!!

Another fact is that Sugar Puffs make your wee smell like Sugar Puffs

I read once that the human body produces more heat per unit mass than the sun

That could be a sign of increased blood glucose levels as the body struggles to deal with the effects of such a sugar rich food.

Excessive consumption of such a high sugar, high carbohydrate food is an open invitation to the body for developing insulin resistance or type 2 diabetes.

Oh bugger

Though it wasn't picked up on my medical

That's great news Pete .  Although it's more difficult to remain healthy later in life it's definitely worth it.

I eat very healthy & i'm very fit, i'd be surprized if i had anything like that, but one never knows

binding force between molecules named as Wan Der Waals forces which is also responsible for surface tension.. their normal behaviour in these temperatures.. remember its -271 celcius which is hard to achieve..

for those interested "cooling to 0 kelvin"

i just brought some H₂O to 273.15K and poured it on a tea bag - that was easy - you're right cem, it's going the other way thats the hard part - as far as i remember my physics absolute zero (0K) isn't achievable 

p.s. I grew up next to the River Kelvin, where Lord Kelvin got his title and hence the unit of temperature 

[Xplicit 2.0]

i thought absolute zero was about -72 C
then again im probably wrong

So that must mean perpetual motion really is possible! :-/
