'10 Physicists Who Transformed Our Understanding of Reality' (co-written with Brian Clegg) is now available. To order you copy, follow this link. '30-second Physics' will be available in March 2016, and '30-second Einstein'
later in the year. I am currently writing two more books for the same
publisher, Constable & Robinson; the working titles of these are '10 Women Who Changed Science' and '10 Things We Have Learnt About Space'.
