Thought for the month
“There is nothing noble in being superior to some other man. The true nobility is in being superior to your previous self.” Probably W.L. Sheldon, US lecturer on ethics (1858 – 1907) rather than Ernest Hemingway.

Sensor technology developments
Sensor technology has developed somewhat since the days of taking canaries down coal mines to detect toxic gases. However it seems that we can still learn from the natural world. In 373 BC, historians recorded that animals, including rats, snakes and weasels, deserted the Greek city of Helice in droves just days before an earthquake devastated the place. A recent study has found significant changes in animal behaviour immediately before an earthquake, possibly linked with airborne positive ions created by the electric charges generated by stressed subterranean rocks grinding together. As Albert Einstein said: Look deep into nature, and then you will understand everything better.
