Science, Technology

Fascinating BBC Horizon programme from 1984 looking at the greatest unsolved problems in mathematics including Fermat's Last Therom (since solved), The Goldback Conjecture, The Riemann hypothesis, the P=NP Problem, and more. Featuring interviews with many modern mathematicians, this documentary also looks at the history of maths and some of if it's major players from Euclid to Bertrand Russell. (www.youtube.com)

It's an alien landscape were magnetic tornado's twist upwards ten's of thousand's of miles. Mysterious dark spots large enough to engulf the earth. And violent eruptions shoots ton's of charged particles into space at speed of over two million miles per hour. This is not some strange world on the other side of the galaxy, this is our Sun. And now, new technologies are allowing us to see it like never before. (www.youtube.com)

The Universe - Strangest Things In The Universe (Full Documentary)

Mysteriously beautiful fractals are shaking up the world of mathematics and deepening our understanding of nature.

A fractal is "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole," a property called self-similarity.

Broadcast (2006) Nature invented a whole range of hi-tec materials long before we invented ceramics and plastics. And not only are they often better, but nature has also invented ingenious ways of building with them. In this programme we travel inside a giant sequoia to find out how nature has built the largest living thing ever, and how that might help us make better bullet proof vests. In the forests of Central America, the breath taking, irridescence of a morpho butterfly in flight is all the more amazing when slowed down over a hundred times.

Anticipation is building in the run-up to presentations of the best-yet evidence for - or against - the existence of the Higgs boson.

The famed particle is a missing link in current theories of physics, used to explain how things gains their mass.

Rumours have been swirling about the findings for weeks, ahead of the announcement on Tuesday afternoon.

It is likely to yield only tantalising hints, as the teams do not have enough data to claim a formal discovery. (www.youtube.com)

Broadcast 2009. Black Holes are one of the most destructive forces in the universe, capable of tearing a planet apart and swallowing an entire star. Yet scientists now believe they could hold the key to answering the ultimate question - what was there before the Big Bang? The trouble is that researching them is next to impossible. Black holes are by definition invisible and there's no scientific theory able to explain them.

National Geographic: Naked Science - Killer Lakes: Since the death of 1,700 people near Lake Nyos in Africa, scientists have uncovered a terrifying series of hazards in lakes across the world. (www.youtube.com)

Broadcast 2010. Famed for their ability to inflict Armageddon from outer space, asteroids are now revealing the secrets of how they are responsible for both life and death on our planet. Armed with an array of powerful telescopes, scientists are finding up to 3000 new asteroids every night. And some are heading our way. But astronomers have discovered that it's not the giant rocks that are the greatest danger - it's the small asteroids that pose a more immediate threat to Earth.
