Find out why physicists believe they might be in a lecture by John D. Barrow at the Bath Royal Literary and Scientific Institution on April 13th.

John D. Barrow FRS has been a Professor of Mathematical Sciences at the University of Cambridge since 1999, carrying out research in mathematical physics, with special interest in cosmology, gravitation, particle physics and associated applied mathematics. He is the author of over 420 articles and 19 books, translated in 28 languages, exploring the wider historical, philosophical and cultural ramifications of developments in mathematics, physics and astronomy. Most importantly (to us anyway), he is the director of the Millennium Mathematics Project of which *Plus* is a part.

The lecture starts at 7:30pm and you can book tickets here (£8/£6 concession).

If you can't get to Bath you can also read Barrow's *Plus* article Are the constants of nature really constant? or listen to Barrow in the accompanying podcast.
