Professor Mary Beard looks beyond the stories of emperors, armies, guts and gore to meet the everyday people at the heart of Ancient Rome's vast empire. In this programme, Mary asks not what the Romans did for us, but what the empire did for Rome. She rides the Via Appia, climbs up to the top seats of the Colosseum, takes a boat to Rome's port Ostia and takes us into the bowels of Monte Testaccio. She also meets some extraordinary Romans: Eurysaces, an eccentric baker, who made a fortune out of the grain trade and built his tomb in the shape of a giant bread oven; Baricha, Zabda and Achiba, three prisoners of war who became Roman citizens; and Pupius Amicus, the purple dye seller making imperial dye from shellfish imported from Tunisia. This is Rome from the bottom up.

brilliant mathematicians, whose genius has profoundly affected us, but which tragically drove them insane and eventually led to them all committing suicide. Georg Cantor, the great mathematician whose work proved to be the foundation for much of the 20th-century mathematics. He believed he was God's messenger and was eventually driven insane trying to prove his theories of infinity. Ludwig Boltzmann's struggle to prove the existence of atoms and probability eventually drove him to suicide.

Discoveries of new planets have revealed countless worlds much stranger than Earth. Some of these strange worlds don’t have stars; others are made out of diamonds. Will we ever find a planet like Earth, or are these distant worlds stranger than fiction?

The BBC's definitive television history of the rise and fall of the Nazis. The series explores how the Nazis came to power, how they ruled, how they treated their occupied territories and, above all, how a cultured nation could be responsible for such acts of inhumanity. How could a political party as fundamentally evil and overtly racist as the Nazis come to power? Acclaimed historian Laurence Rees exposes popular myths and encourages understanding of the real forces that led to one of the darkest chapters in modern history. Was it simply the hypnotic power of Hitler's rhetoric? Did the Gestapo really impose themselves by terror on an unwilling population?

When ancient architects completed construction on the Great Pyramid at Giza, they left behind the greatest riddle of the engineering world—how did builders lift limestone blocks weighing an average of two and a half tons 480 feet up onto the top of the Pyramid? For centuries, adventurers and Egyptologists have crawled through every passageway and chamber of the Pyramid, measuring and collecting data in an attempt to determine how it was built. For the first time, a revolutionary theory argues that the answer may be inside the Pyramid. Architect Jean-Pierre Houdin and Egyptologist Bob Brier use 3-D software to unlock the secret.
