John R. Gribbin (born 19 March 1946)[1] is a British science writer, an astrophysicist, and a visiting fellow in astronomy at the University of Sussex.

[2] His writings include quantum physics, human evolution, climate change, global warming, the origins of the universe, and biographies of famous scientists.

[7] In February 1982, he and Plagemann published The Jupiter Effect Reconsidered, claiming that the 1980 Mount St. Helens eruption proved their theory true despite a lack of planetary alignment.

[citation needed] A review of The Universe: A Biography in the journal Physics World praised his skill in explaining difficult ideas.

[14] A Wall Street Journal review of Flower Hunters (co-authored with Mary Gribbin) described the writing as "pedestrian", with plenty of domestic detail but a failure to convey a larger cultural context.
