For one night only, Professor Brian Cox takes an audience of celebrity guests and members of the public on a journey into the wonderful universe of the Doctor, from the lecture hall of the Royal Institution of Great Britain. Drawing on the latest theories as well as 200 years of scientific discoveries and the genius of Einstein, Brian tries to answer the classic questions raised by the Doctor. Can you really travel in time? Does extra-terrestrial life exist in our galaxy? And how do you build something as fantastical as the TARDIS?

The story of the greatest physicists of the 20th century and the discoveries they made.

Professor Bruce Denardo attempts to prove whether there is any truth behind the legend of the Bermuda Triangle, where many ships and planes have disappeared in mysterious circumstances. New investigation techniques reveal the truth behind the infamous disappearance of Flight 19. Graham Hawkes is also able to reveal, by using a state-of-the-art submarine, how five wrecks mysteriously wound up 730 feet down in the heart of the Bermuda Triangle.

In 1957, Britain exploded its first megaton hydrogen bomb - codenamed Operation Grapple X. It was the culmination of an extraordinary scientific project, which against almost insuperable odds turned Britain into a nuclear superpower. Featuring access to the top-secret nuclear research facility at Aldermaston, the programme features interviews with veterans and scientists who took part in the atomic bomb programme, some speaking for the first time, and newly released footage of the British atomic bomb tests.
