Matt Parker is no stranger to maths mistakes and so he sets out to fix them all. At last: a rigorous comedy show not afraid to show its working out. Being wrong has never felt so right.

Festival of the Spoken Nerd are the science comedy phenomenon that will feed your brain, tickle your ribs and light your Bunsen burner. Full Frontal Nerdity guaranteed! Stand-up mathematician Matt Parker (Discovery Channel You Have Been Warned), experiments maestro Steve Mould (ITV1 I Never Knew That About Britain) and geek songstress Helen Arney (BBC2 Coast) mix astonishing science with statistically significant comedy, plus experiments that electrify their audiences – sometimes literally. Since their last smash hit tour show Full Frontal Nerdity, the Nerds have filmed their first DVD (available now) and racked up over a million views on YouTube for their experiments, songs and stand-up. As well as sell-out shows all over the UK, the Nerds have performed at Shakespeare’s Globe, Hammersmith Apollo with Robin Ince and Brian Cox, The British Library, TED, Udderbelly and Latitude Festival.
