I am a freelance writer and photographer, and I do some broadcasting on radio and television. I like working from home, often with a cat helping on my desk. When I have to travel I like to do it by bike and train.

In March 2011, I opened a new Exhibition at The Science Museum entitled "James Watt and our World". This brilliant new exhibit features Watt's original workshop, completely reassembled and moved to the Science Museum in London. Watch a video about it on YouTube.

I give a lot of public talks and lectures. See Events and Talks to find out where you can see me.

My Books:

I have just released The Book of Time, published by Mitchell Beazley in October 2011.

The Book of Time From water clocks to atomic chronometers, people have always tried to keep track of time, while wondering what it is, and why women, plants, and fish have cycles linked to the Moon. How can a jellyfish sting you in less than a microsecond, although you won’t feel the pain for a million times longer? Does time really slow down when you are bored and speed up in emergencies? Was there a beginning of time, and will there be an end? The Book of Time: Everything You Need to Know About the Biggest Idea in the Universe

I am working on two new books, one entitled "Engineers" for Dorling Kindersley and a book of "Pop-Up Inventions" with Walker Books

My previous book "Science" was published by Dorling Kindersley in September 2009. Read a review of the book which is described as "a brilliant introduction to science ..... with explanations that don't leave you reeling".

I also acted as editorial consultant for this book's companion "History", a vast history book also published by Dorling Kindersley. Full details can be found on my Books page. There's also a review from The Times and an article I've written regarding the book in Local History Magazine.

Why I support the Historic Royal Palaces:  Prince Albert was a champion of Victorian innovation and industry - and apparently very fond of gadgets! In this video I champion the campaign to transform Kensington Palace by 2012, I tell you a bit more about my love of the Victorians - and explain why you should play your part in the palace's future.
