In Our Time

Jupiter is the largest planet in our solar system, and it’s hard to imagine a world more alien and different from Earth. It’s known as a Gas Giant, and its diameter is eleven times the size of Earth’s: our planet would fit inside it one thousand three hundred times. But its mass is only three hundred and twenty times greater, suggesting that although Jupiter is much bigger than Earth, the stuff it’s made of is much, much lighter. When you look at it through a powerful telescope you see a mass of colourful bands and stripes: these are the tops of ferocious weather systems that tear around the planet, including the great Red Spot, probably the longest-lasting storm in the solar system. Jupiter is so enormous that it’s thought to have played an essential role in the distribution of matter as the solar system formed – and it plays an important role in hoovering up astral debris that might otherwise rain down on Earth. It’s almost a mini solar system in its own right, with 95 moons orbiting around it. At least two of these are places life might possibly be found.

Melvyn Bragg and guests discuss the remarkable diversity of the animals that dominated life on land in the Triassic, before the rise of the dinosaurs in the Jurassic, and whose descendants are often described wrongly as 'living fossils'. For tens of millions of years, the ancestors of alligators and Nile crocodiles included some as large as a bus, some running on two legs like a T Rex and some that lived like whales. They survived and rebounded from a series of extinction events but, while the range of habitats of the dinosaur descendants such as birds covers much of the globe, those of the crocodiles have contracted, even if the animals themselves continue to evolve today as quickly as they ever have.

Melvyn Bragg and guests discuss the man who, in 1905, produced several papers that were to change the world of physics and whose name went on to become a byword for genius. This was Albert Einstein, then still a technical expert at a Swiss patent office, and that year of 1905 became known as his annus mirabilis ('miraculous year'). While Einstein came from outside the academic world, some such as Max Planck championed his theory of special relativity, his principle of mass-energy equivalence that followed, and his explanations of Brownian Motion and the photoelectric effect. Yet it was not until 1919, when a solar eclipse proved his theory that gravity would bend light, that Einstein became an international celebrity and developed into an almost mythical figure.

Melvyn Bragg and guests discuss the Austrian-born film director Fritz Lang (1890-1976), who was one of the most celebrated film-makers of the 20th century. He worked first in Weimar Germany, creating a range of films including the startling and subversive Mabuse the Gambler and the iconic but ruinously expensive Metropolis before arguably his masterpiece, M, with both the police and the underworld hunting for a child killer in Berlin, his first film with sound. The rise of the Nazis prompted Lang's move to Hollywood where he developed some of his Weimar themes in memorable and disturbing films such as Fury and The Big Heat.

Melvyn Bragg and guests discuss the woman who inspired one of the best known artefacts from ancient Egypt. The Bust of Nefertiti is multicoloured and symmetrical, about 49cm/18" high and, despite the missing left eye, still holds the gaze of onlookers below its tall, blue, flat topped headdress. Its discovery in 1912 in Amarna was kept quiet at first but its display in Berlin in the 1920s caused a sensation, with replicas sent out across the world. Ever since, as with Tutankhamun perhaps, the concrete facts about Nefertiti herself have barely kept up with the theories, the legends and the speculation, reinvigorated with each new discovery.
