Scientific Certainty; What’s in a Theory?
Posted by: ozymandias1 on: January 5, 2009
Picking out the greatest disservice we do to out students as science-teachers is no easy task; there is quite an impressive list to pick from. Not reflecting or even being aware of this is in itself significant. I think C.S. Pierce put it best when he wrote “Find a scientific man who proposes to get [...]

Unusual resource for explaining Joule’s Law
Posted by: ozymandias1 on: October 23, 2008
An offshoot of Joules’ Law is that when transmitting electrical power, the current is kept as low as possible in order to reduce energy losses associated with heat of the electrical cables. Because the power being transferred is the product of the voltage and the current, we can still get the same power transferred if [...]

Just got back from wonderful New Zealand yesterday and came across some of these impressive deals. Digital calipers from aldi for €10, available from Sunday 13th (checkout blowtorch available also for €10).
