A Greek shipwreck holds the remains of an intricate bronze machine that turns out to be the world's first computer
In 1900, a storm blew a boatload of sponge divers off course and forced them to take shelter by the tiny Mediterranean island of Antikythera. Diving the next day, they discovered a 2,000 year-old Greek shipwreck. Among the ship’s cargo they hauled up was an unimpressive green lump of corroded bronze.
Rusted remnants of gear wheels could be seen on its surface, suggesting some kind of intricate mechanism. The first X-ray studies confirmed that idea, but how it worked … Ler mais

The quest to explain the nature of reality is one of the great scientific detective stories. Are we are part of a cosmic hologram? Do we exist in an infinity of parallel worlds?
There is a strange and mysterious world that surrounds us, a world largely hidden from our senses. The quest to explain the true nature of reality is one of the great scientific detective stories.
Clues have been pieced together from deep within the atom, from the event horizon of black holes, and from the far reaches of the cosmos. It may be that that we are part of a cosmic hologram, projected from the edge of the universe. Or that … Ler mais
Leonardo da Vinci is well known for his inventions as well as his art. But new evidence shows that many of his ideas were realized long before he sketched them out in his notebooks — some even 1,700 years before. Was Leonardo a copycat?
Leonardo da Vinci is, of course, best known as one of the world’s greatest artists. At his death in 1519, he was famous for such masterpieces as the Mona Lisa and The Last Supper. But he was more than a painter, he was also a musician, writer, and showman. In the pages of his notebooks, written in a secretive reverse script, and unpublished for more than 400 years, we discover yet another Leonardo, the man of science.
His notebooks … Ler mais
A look at dark matter and dark energy ahead of the Large Hadron Collider being switched on in March 2015, having been upgraded
Scientists genuinely don’t know what most of our universe is made of. The atoms we’re made from only make up four per cent. The rest is dark matter and dark energy (for ‘dark’, read ‘don’t know’). The Large Hadron Collider at CERN has been upgraded. When it’s switched on in March 2015, its collisions will have twice the energy they did before. The hope is that scientists will discover the identity of dark matter in the debris.
The stakes are … Ler mais
