The fox, as has been pointed out by more than one philosopher, knows many small things, whereas the hedgehog knows one big thing. Ronald Reagan was neither a fox nor a hedgehog. He was as dumb as a stump. He could have had anyone in the world to dinner, any night of the week, but took most of his meals on a White House TV tray. He had no friends, only cronies. His children didn't like him all that much. He met his second wife?the one that you remember?because she needed to get off a Hollywood blacklist and he was the man to see. Year in and year out in Washington, I could not believe that such a man had even been a poor governor of California in a bad year, let alone that such a smart country would put up with such an obvious phony and loon.

The eight climbers killed on the single deadliest day on Everest may have been victims of the "sky falling in", according to a study.

An analysis of weather patterns in May 1996 suggests the mountaineers died when the stratosphere sank to the level of the summit, 29,000ft above sea level.

The freak weather caused pressure and oxygen levels to plunge within the "death zone" - the area above 26,000ft where the oxygen is extremely thin.

Normally Everest's summit lies just below the atmospheric layer. But on May 10, the day of the disaster, there were two fast-flowing air streams, called jet streaks, moving over the mountain.

The world's oceans contain far more cold-water coral reefs than experts had realised, the United Nations says.

The reefs are usually found in deeper, cooler water than tropical corals, and many are up to eight millennia in age.

A report issued by the UN Environment Programme to mark World Environment Day on 5 June says the reefs are widespread from Greenland to sub-Antarctic waters.

Test subjects can't see the invisible beam from the Pentagon's new, Star Trek-like weapon, but no one has withstood the pain it produces for more than three seconds.

People who volunteered to stand in front of the directed energy beam say they felt as if they were on fire. When they stepped aside, the pain disappeared instantly.

During many of these bust-baring periods, it would have been shocking for a woman to show her shoulders or legs, which were more associated with male sexuality.

Turing may not be a household name, but his achievements have been recognised.

A road has been named after him in Manchester, where he lived for the latter years of his life when he joined Manchester University.

There is also a bronze statue of him in Sackville Park in the city's gay village, where he sits on a bench, apple in hand.

He has even featured in a Doctor Who book.

And the home of his birth in London also has a blue plaque outside, which will now be joined by a plaque outside the place of his death on Adlington Road, in Wilmslow.

Dr Kuehne noticed that the war between Atlantis and the eastern Mediterranean described in Plato's writings closely resembled attacks on Egypt, Cyprus and the Levant during the 12th Century BC by mysterious raiders known as the Sea People. As a result, he proposes that the Atlanteans and the Sea People were in fact one and the same.

Louis XVII's short life was the stuff of nightmares. He lost his parents to the guillotine.

He was locked in Paris' Temple prison for three years -- for part of that time, in solitary confinement in a darkened cell, without anyone to wash him or clean up after him, said historian Philippe Delorme.

The boy finally died of tuberculosis in 1795, his body reportedly ravaged by tumors and scabies.

The child's corpse was dumped in a common grave -- but first, a doctor secretly carved out his heart in keeping with a tradition of preserving royal hearts separate from their bodies.
