Dara O Briain: School Of Hard Sums

Brains and brawn go head to head once again as Dara O'Briain presents the light-hearted science show. Taking up Dara's problem-solving challenge here is Andi Osho.

Dara O'Briain returns for more mathematical mayhem, and this week he is joined by comedian Andi Osho. With no mathematical training at all, Dara and Andi will attempt to solve problems posed by Oxford University professor, Marcus du Sautoy.

The theme for this week's show is that you can't argue with logic and in the first challenge, Marcus challenges Dara and Andi to use logic to re-label some mixed up bottles of wine, without being able to see what they are. We needed a stiff drink after trying to work it out, but Andi manages to figure out what should go where by applying the principles of logic.

More fun experiments include using weights to find a fake coin and working out how many trips in the lift a virgin would have to take to not get killed by a vampire. It sounds like a right pain in the neck, but it's completely logical - honest.
