[time-nuts] Synchronised pendulums

[Alan Melia]

This topic has arisen several times in the past and again recently. This 
month's Physics World, the magaizine of the UK's Institute of Physics 
carries an article on page 36 describing Christiaan Huygens experiments in 
the 1660s, and follows up with descriptions of some modern academic work.

I suspect this are available through the usual sources in many countries.
