‘Why Hasn’t Scotland Exploded ?' Not something, I imagine, you'd ask yourselt outside a political discussion, but Dr Eric Voice, who will be talking on the subject (Tue 4 April, see listings) is relerring quite unequivocally to the whizz-bang nuclear type ot explosion. Nuclear energy is not as recent as we might think, in tact, as he points out ‘nature's done it all betore . . . there are six natural nuclear reactors under the ground in West Alrica. They occur where there are large deposits at uranium, and there is a lot oi uranium in Scotland‘. How close did Scotland come to being a substantially warmer place than it is now? Dr Voice will reveal all, taking in, as he races through the last lew hundred million

years at earth history, the Big Bang, supernovae and the origins ol lite on Earth.

Terrestrial rumblings ot ditterent types are the subject at ‘Earthquakes and Space Weather— Predicting the Future‘ (Fri 7 April, see listings next issue). Dr Chris Browitt will be giving us a chance to ‘listen' to earthquakes and distinguish between their many diiterent signature tunes. He‘ll also be talking about ‘man made' earthquakes which, perhaps surprisingly, strike Edinburgh not too intrequently. In the same talk Dr Dave Barraclough will be discussing the ‘space weather thrown at us by the sun’, touching on, why, last week, sun spot activity caused compass needles here on earth to swing away trom North by 8 degrees. Discussions in the bar are welcomed.

For a glimpse at the modern-day methods used by geologists, take advantage of the Open House at the British Geological Survey's Scottish headquarters (Sat 8 and Sun 9 April, see listings next issue). You'll be able to descover how satellites have revolutionised the surveying ol the planet. Other events to look out tor are ‘Pterosaurs: The Furry Dragons‘ (Thurs 6 April,see listings) and the ‘Geological Guided Walk' oi Edinburgh (Sat 8 April, see listings next issue).
