A tweet purporting to be ((Yes, I know, but it was retweeted by Thomas Woolley, who should know.)) from the press office of UKTV, the company that owns the channel Dave, has confirmed that the TV show Dara O Briain: School of Hard Sums is to return for a second series (we at least thought we knew this in July). It also says that production company Wild Rover are looking for maths students to take part. The tweet asks you to email maths@wild-rover.com to express an interest. You might remember that the first series, which aired in April-June, did very well compared with other programmes on the channel.
