While it might seem that science is firmly in the telling camp and literature in the showing camp, scientific diaries and autobiographies seem to be spaces in which scientists have decided to show rather than tell. To explore how scientists write and why they write, we’ve invited a novelist and scientist, Professor Sunetra Gupta (University of Oxford), to share her experiences of writing in different ways and for different reasons. We then turn to a panel of historians of science, to ask them why some notable scientists of the last three centuries (Boyle, Hooke, Petiver, Banks, Solander, Blagden and Tyndall) kept a diary and how they went about it. The event was recorded on January 27 2017 at the Royal Society, and was organised by the Royal Society in association with the Constructing Scientific Communities project funded by the Arts and Humanities Research Council For more events like this, see our schedule - ow.ly/KhTi306gTN1
