26 August Ecological design: Inventing the future. Featuring ideas and prototypes by designers who have pioneered the development of sustainable architecture, cities, energy systems, transport and industry.
Discovery Sci Trek, 8am and repeated 8pm, so the chances are you'll be watching it in your pyjamas either way.
26/27 August The far twittering and oysterperch railway. A special model exhibition - courtesy of the Warley Model Railway Club - based on cartoons popular in the 1940s and 1950s, supplements the regular attractions. How quaint.
National Railway Museum.
Tel, (01904) 621261 www. nrm. org. uk 27 August A Bridge Too Far. Dirk Bogarde stars as the architect who is the toast of the goateed, black polo neck sweater wearing cognoscenti because of his innovative design led solutions. However, his elevated status comes under threat when he builds a fancy bridge that wobbles when people walk across it. Anthony Hopkins co stars as the civil engineer with a drink problem who thinks all bridges wobble after a couple of pints. Watch out for Lawrence Olivier and Edward Fox as the two pedestrians.
BBC2 9.40pm 27 August Who built the pyramids? Well we know for certain that it wasn't Nigella Lawson or Chris de Burgh. I know the pyramids feature quite often in Foresight, but I find them very interesting. So there.
National Geographic. 10.30pm 29 August Ace In the Hole. Kirk Douglas plays a cynical reporter determined to get the big scoop.
Let me put your minds at rest, readers. Of the bona fide news gatherers who make up the NCE news team, I know only decent, hard working men and women.
They are people who would never use chicanery to get a story, many of them go to church, some enjoy cuddly toys, while others collect ornamental thimbles from the Franklin Mint. Believe me, they're harmless and very approachable.
Film Four, 6pm 31 August Island eaten by rats. Until the early 1960's, Big South Cape, a small island of New Zealand, was a teeming biological time capsule.
That was until 1962 when ships' rats got ashore. Nothing much to do with civil engineering friends, but a great premise for a cheesy horror film.
National Geographic, 12.30pm 31 August Absolutely Fabulous. What does the BBC do when it can't come up with a new idea for successful situation comedy? Why, it pays shed loads to people to come out of retirement and rehash something that was once successful but ended up tired and self satisfied. With a bit of luck noone will notice and the BBC can cheekily add the word 'classic' to descriptions of the programme.
BBC1 9pm Ends September 30 Maudsley, Sons & Field:
Engineering pioneers. Little known to the public, Henry Maudsley is regarded as a key figure in engineering. To mark the 160th anniversay of his death is a special exhibition of his life and work, which included coin presses for the Royal Mint, the axle of the Earls Court Wheel and numerous marine engines. Helluvaguy.
Kew Bridge Steam Museum.
