NOVA leads viewers on a mathematical mystery tour -- a provocative exploration of math's astonishing power across the centuries. We discover math's signature in the swirl of a nautilus shell, the whirlpool of a galaxy and the spiral in the center of a sunflower. Math was essential to everything from the first wireless radio transmissions to the prediction and discovery of the Higgs boson and the successful landing of rovers on Mars. But where does math get its power? Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists and engineers, follows math from Pythagoras to Einstein and beyond, all leading to the ultimate riddle: Is math an invention or a discovery? Humankind's clever trick or the language of the universe?

M.C. Escher is among the most intriguing of artists. In 1956 he challenged the laws of perspective with his graphic Print Gallery and his uncompleted master-piece quickly became the most puzzling enigma of modern art. Fifty years later, can mathematician Hendrik Lenstra complete it? Should he?

There’s something very odd going on in space – something that shouldn’t be possible. It is as though vast swathes of the universe are being hoovered up by a vast and unseen celestial vacuum cleaner. Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: ‘It left us quite unsettled and jittery’ he says, ‘because this is not something we planned to find’. The accidental discovery of what is ominously being called ‘dark flow’ not only has implications for the destinies of large numbers of galaxies – it also means that large numbers of scientists might have to find a new way of understanding the universe. Dark flow is the latest in a long line of phenomena that have threatened to re-write the textbooks. Does it herald a new era of understanding, or does it simply mean that everything we know about the universe is wrong? .

Professor Jim Al-Khalili investigates the amazing science of gravity. As well sculpting our universe, gravity also affects our weight, height and even the rate at which we age.

A documentary produced in 1979 to celebrate the centenary of the birth of Albert Einstein. Narrated and hosted by Peter Ustinov and written by Nigel Calder.

Until recently geometry was 'cold', incapable of describing the irregular shape of a cloud, the slope of a mountain or the beauty of the human body. With fractal geometry, Benoit Mandelbrot gave us a language for our natural world. In this captivating documentary, the man himself explains this groundbreaking discovery.
