Subsequently he undertook a history of science DPhil at Wadham College, Oxford. He is a historian by training and his special interests are astronomy and scientific biography.

Chapman has been based at Oxford University for most of his career, as a member of the Faculty of History, He is an accomplished lecturer and public speaker (including as visiting professor at Gresham College in London).

Lecture synopsis

 ‘The Wonderful Century; how the ‘modern’ universe was born, 1890-2000′

‘Astronomy has advanced rapidly since the invention of the telescope in 1609.  First came bigger telescopes, and in the early Victorian age, spectroscopy, photography, and early electrical physics. But it was after 1890 that a true a true sea-change in the sheer scope and scale of astronomy began, as there would also be in other sciences.  For new technologies now ‘cross pollinated’ across the whole range of the experimental sciences. X-Rays, atomic radiation, the electron, and new concepts of the atom heralded in the 20th Century. Then things flew thick and fast, with Einstein’s revolutionary concepts of ‘space-time’, and Eddington’s  and Chandrasakher’s models of stellar evolution. But a true watershed was crossed between 1924 and 1929, when Edwin Hubble demonstrated that the ‘nebulae’ were galaxies is their own right, rather than being parts of our own Milky Way, and were apparently receding into infinite space at enormous speeds. Then after 1927, the Belgian Roman Catholic Priest physicist, Father Georges Lemaitre demonstrated mathematically that everything was flying apart, apparently from an original ‘primal atom’;  a theory which Fred Hoyle later dismissed as a mere ‘Big Bang’. And flying thick and fast in ‘The Wonderful Century’ came radio astronomy, space travel, black holes, dark matter, and great communicators like Sir Stephen Hawking, Sir Patrick Moore and Carl Sagan, who took astronomy to the world.

And now we are 18 years into another century, which could well end up being even more wonderful than the 20th.   So be prepared to hold your breath !’
