For readers who are interested in the ‘new physics’ – quantum weirdness, string theory etc – make sure you check out the official website for the PBS-NOVA feature “The Elegant Universe”. Based on physicist Brian Greene’s best-selling book (and hosted by him as well), the series attempted to explain the strange concepts inherent in ‘String Theory’ such as extra dimensions. The website is packed full of information – and for broadband users, the great attraction is that the whole series is available to be watched for free online. Great stuff.
