Micro wave beds are good too. You get eight hours sleep in four minutes.

 

Insomniacs are Go. 

 

Mogadon micro tablets. So small you never saw them.

I still drop a tab of acid a week. Problem is these days it's Alendronic Acid to stop my osteoporosis getting worse... :)

Radiators use 2 mechanisms to transfer heat, conduction and radiation.   Both can heat an adjacent medium such as air, which if it can move, can move the heat elsewhere, which is called convection.  But there are only the 2 fundamental mechanisms at work in getting the heat out of the source.  Convection is a secondary process.

Well that's not what they taught at Uddingston Grammar , a  Secondary School, which puzzled me, but it was a Secondary school, so what can you expect? Second class actually.

My English teacher told me he was surprised I passed my Higher, he was the only one in the Department with a Degree, can you imagine that?

at B grade. Well obviously, I needed it to go to College, the five years of boring teaching in that very ordinary place, a complete waste of my valuable time, but at the time there was no internet, so I knew nothing else, kids today have it easy. :)

So the fact they're called radiators isn't to do with them radiating heat then? Just asking.

The radiation is the smaller bit
