Happy birthday to our lifelong friend in South Kensington: the Science Museum. It's 100 years ago today since the much-loved institution broke away from the V&A to go it alone. The museum remains a temple to the modern world and an inexhaustible supply of curiosities to both the young and old. To celebrate the anniversary, the museum has an enlightenment of events lined up over the weekend. Gallery characters will bring to life the likes of George 'Five pound note' Stephenson, Rosalind 'DNA' Franklin and Gene 'Last man on the moon' Cernan. Special tours will pick out themed highlights of the collection, or recreate the experience of visiting the Science Museum in days gone by (presumably by pointing out this quaint gallery). Meanwhile, the museum would like you to share your favourite memories of the venue, and vote for the greatest scientific icon from their collection.
