Physics: Benefits and Hazards (8 Parts)

Synopsis

1: carbon dioxide and other gases in the atmosphere. Describeds some of the features of current models including uncertanties introduced by could and ocean absorption.
2: introduces nuclear radiation and looks at the internal construction of various types of counter including the Geiger counter.
3: magnetostatics: investigates various materials for their magnetic properties. Looks at applications such as suspension in the Maglev railway, lining up nails to be packed into boxes, and magnet-based keys.
4: explores electrostatic phenomemna in the context of applications ranging from the use of capacitors in strain gauges and sound-detector range finders, through qauartz crystal displays to xerography and the analysis of DNA. Describes some of the hazards of the buildup of elelctrostatic charge, including lighting and charged oil pipes.
5: discusses ariels and the effects of different shapes and sizes, frequency, bandwidth, dipoles and arrays of ariels.
6: illustrates the basics of lasers with laboratory experiments.
7: shows some of the applications of physics in the manufacture of chocolate.
8: looks at nuclear magnetic resonance and the interpretation of NMR spectra.
