BBC Proms 2009 (Saturday, BBC Two, 7pm) Don’t let it be said that classical music is a dying artform.

This eight-week summer season of the BBC Proms is a real treat for fans of the genre — and even more so than usual this year. Yes, 2009 will see the number of concerts reach the 100 mark for the first time, so that’s more music for your money than ever before.

Katie Derham and Suzy Klein present this latest edition as principal conductor Vasily Petrenko leads a performance by the National Youth Orchestra at the Royal Albert Hall in London.

The concert features Tchaikovsky’s Piano Concerto No 1 in B flat minor, performed by Stephen Hough, Lutoslawki’s Concerto for Orchestra and Respighi’s survey of the Italian capital, Roman Festivals.

If you don’t consider yourself a fan of classical music already, then you could do a lot worse then use this as a starting point. Tune in and enjoy.

Revelations: Talking to the Dead (Sunday, Channel 4, 7pm) Proving there’s more to religious programming than Songs of Praise, Channel 4’s Revelations strand has certainly served up some quality TV while examining the lives of believers and non-believers alike.

Tonight, film-makers gain unprecedented access to a Spiritualist church to provide an intimate portrait of people whose worlds have been transformed by a belief in life beyond the grave.

One of more than 400 Spiritualist churches across the UK, this East London outpost has been around for 80 years. The services are led not by priests, but by visiting mediums who are invited to give demonstrations of their ability to make contact with the dead.

This film about grief and loss lifts the lid on a belief system which many ridicule, meeting mediums and members of the congregation and exploring the different paths that have led them to the church.

Is their religion a fool’s paradise or do Spiritualists have access to a world that most of us don’t contemplate: the afterlife?

Bang Goes the Theory (Monday, BBC One, 7.30pm) How many of you ever really paid all that much attention in science class? Was it because the lessons seemed boring, the teachers dull and concepts difficult to grasp?

Well, whatever your excuses might be, here’s one show that is bound to keep even the least science-enthused mind entertained and educated for 30 minutes.

In this latest edition, Dallas Campbell traces the global journey of 30,000 indestructible plastic ducks, while Liz Bonnin goes on manoeuvres at the bottom of the Baltic Sea in the Royal Navy’s latest state-of-the-art search-and-rescue submarine.

Plus, Dr Yan Wong challenges people in Cardiff to take on the might of friction, while Jem Stansfield undertakes what might prove to be the most foolhardy experiment of all — using two domestic vacuum cleaners to climb up the side of a building.
