Inside Einstein’s Mind: The Enigma of Space and Time

BBC Four, 9.00pm

The story of the most elegant and powerful theory in science – Albert Einstein’s general relativity. And it’s narrated by David Tennant – things could get seriously awesome!

When Einstein presented his formidable theory in November 1915, it turned our understanding of gravity, space and time completely on its head. Over the last 100 years, general relativity has enabled us to trace the origins of the universe to the Big Bang and to appreciate the enormous power of black holes.

To mark the 100th anniversary of general relativity, this film takes us inside the head of Einstein to witness how his idea evolved, giving new insights into the birth of a masterpiece that has become a cornerstone of modern science. This is not as daunting as it sounds – because Einstein liked to think in pictures.

The film is a magical visual journey that begins in Einstein’s young mind, follows the thought experiments that gave him stunning insights about the physical world, and ultimately reaches the extremes of modern physics.

Simply Nigella: Christmas Special

BBC Two, 8.00pm

In this hour-long special, Nigella shares her fool-proof guide to stress-free festive cooking and easy entertaining – with a line-up of celebratory dishes which are both indulgent and practical.

Inspired by the sparkling Christmas lights in Kansas City USA, Nigella shows us how to have our most relaxed, most spectacular Christmas yet. She’ll introduce us to the local, home-spun food that has inspired some of this year’s favourite festive recipes, adding a British twist back in her kitchen.

Her oh-so-slow cooked black treacle ham replaces the traditional turkey as the party centre piece, paired with a refreshingly bright medley of sweet and sour vegetable slaw.

Nigella treats her guests to not one, but three sumptuous cakes to tuck in to. Her trio of bundt cakes begins with a delicately flavoured cider and five spice sponge, topped with an indulgent salted caramel sauce, followed by a delicious lemon and thyme version and ending with a pumpkin bundt, adorned with an aromatic orange icing.
