Peter Hill Explains

We look at a simple approach to the thermal radiation equation. The parts of the density of states, and the Bose Einstein statistics are used. Podcast

Planck was deeply involved with Hitler, and lost all his sons in the War. The interest in the answer is more in the thinking of those who ask the question. Different classes of scientists are considered, from the masters of equations to the dynamic mind of Einstein to the modern day scientist bound deeply to computer simulations. Podcast

The  problem of getting light from Point A to Point B as been solved by the fascinating invention of Optical Fibres.  We look as using mirrors, then look a lenses but how do we get glass so clear light can travel through it for 600 km? Podcast

A simple look at Wien's Law, Stephan's Law, and Planck's equation Podcast

This two stage strategy is explained on a 10 x 10 grid. Podcast

The intensity of watching a chemical reaction and the grams pile on is a really intense experience for students (I am told).  I recommend the oxygen generators (really nitrogen extractors) as standard school equipment. Podcast

I have found chance encounters with the Vatican marriage annulment computer so interesting. As I have been educated various lessons on aerial baptism really got my attention. The various Papal hammers were great to read about. The Vatican war ships were so interesting, but trying to tell my mates about it showed "I was in too deep" into study Podcast

This timeless classic school experiment shoots a tube of foam out of a measuring cylinder. Some tips like warming the cylinder first and putting an ember into the oxygen foam are reviewed Podcast

Take a journey back in time to when things were relative to the dimensions of the king and the fractions of the day. Overnight concrete standards of the meter, kilo have been replaced by formulae that few people have a real sense of. Podcast

You can really gain an intense insight into solubility and how water surrounds ion by heating up this precipitate and letting it recrystallize as a spectacular 'gold' rain Podcast
