Waterloo Road 8pm, BBC1 Back after its mid-season hiatus, Waterloo Road might be rested, but it's no less volatile. The story of the last few episodes – merger with "posh school" as directed by Mad Max, the regional superhead, brings chaos among teachers – all peacably resolved, the show returns with a bang. The grumpy and bewildered Grantley doesn't know he's doing anything particularly stupid when he lets Bianka Vale go home with her father, Gary. As it turns out, there's a court order against him, and things do not proceed smoothly. Luckily, head Rachel is primed to smoulderingly intervene. Cracking Antiques 8.30pm, BBC2 Antique doesn't necessarily mean expensive. That's the central message of a makeover show that cleverly combines recession-friendly penny-pinching with "oh-we-found-that-in-a-little-place" snobbery. Each week jolly interior designer Kathryn Rayward and antiques expert Mark Hill, who is possibly part-Vulcan, help a nervous buyer pick out pieces that are cheaper than new yet better, and with a resale value. First up, Rebekah Prince from Essex dreams of a rococo-style boudoir. Don't tell anyone we said this, but it's guilty pleasure telly of the highest order. Beautiful Minds 9pm, BBC4 A new series that looks at the thinking of three influential but offbeat scientists whose pioneering work has led to some startling scientific discoveries. Sir Tim Hunt and James Lovelock are coming up, but we start with Dame Jocelyn Bell Burnell who, though she may not be a household name, is a hugely important astrophysicist. When she was a PhD student she discovered the pulsar, a phenomenon linked to supernova explosions, which changed the way we think about the universe. Bell Burnell talks about how she overcame sexist attitudes when she first studied physics and how we are all children of the stars. Bruce Forsyth: A Comedy Roast 10pm, Channel 4 A "roast" in this instance is a kind of good-natured ragging session: the elderly golfing enthusiast is mocked by a panel of comedians, all of whom seem as perplexed as he is as to what they're doing there. Jimmy Carr , not a performer known for his amiability, is the master of ceremonies, seemingly on his best behaviour while a panel including Jack Dee and Barry Cryer share their Brucie-based reminiscences.
