30th November 2018 – Early Indian Astronomy and the Birth of Zero, Dr Peter Ford MBE and Deepali Gaskell

This talk starts in Georgian Bath where former members of the British East India Company came to take the waters and exchanged ideas about the mathematics that they had found in Bengal. It will trace the development of Indian Mathematics and the vital concept of Zero from its origins in ancient astronomy to its use in commerce and science.

Dr Peter Ford was a shadow trustee of the reformed BRLSI from 1990-1993. He was then one of the first trustees representing the University of Bath and later the membership of the BRLSI. He has lived in Lansdown Crescent for forty years half of which was spent in the Physics Department of the University of Bath. He was chair of the William Herschel Society for nine years. In 2008 he was awarded MBE in the Queen’s New Year Honours List for “services to higher education and science”.
Deepali Gaskell. Marriage brought Deepali to Bath, where she now lives. Her interest in Astronomy and Mathematics nurtured by her mother who was an historian and archaeologist was revived when she came across, in her voluntary work with the National Trust, the collection of books in the library at Stourhead which included the Asiatick Researches commissioned by the British East India Company in the 1770’s. This has provided much of the material for this talk.
Deepali has also referred to the Records Office and to the collection in the archives of BRLSI, where she found Newton’s Principia Mathematica, Max Muller’s translation from the Veda, and Journals of the East India Company all of which helped to produce this talk. Deepali is on the Publications and Website committees at BRLSI.

4th January 2019, Deborah Ireland – Hasselblad and the Moon Landing

Hasselblad and the Moon Landing

On 20 July 1969, as part of the Apollo 11 space program, Neil Armstrong and Buzz Aldrin became the first people ever to set foot on the Moon. Their iconic small steps were captured forever by the camera the astronauts carried with them: the Hasselblad 500EL. The remarkable images taken with this camera provide an enduring record of one of humankind’s most extraordinary adventures: but the development of the camera involved a great leap in technology that lasted almost as long as the space program itself. The Hasselblad & The Moon Landing looks at the history of the Apollo 11 mission through the lens of the Hasselblad, while narrating the parallel tale of the challenge to create a camera that could work on the Moon. It considers the cameras used, and the photographs captured, during the Space Race between Russia and America; looks in detail at the experience of taking photographs on the Moon for the first time; and reflects on the processing, preserving and legacy of those images, and the part they play in the enduring conspiracy theories that claim the Moon Landing to have been a grand hoax. The second half of the book presents a commemorative album of photographs taken in space using the Hasselblad 500EL. While the Apollo 11 astronauts left their three cameras behind on the Moon, where they remain to this day, they brought back film magazines containing 1,400 photographs. A selection of the finest of these is shown alongside the mission timeline and transcripts of the conversations between the astronauts and mission control at Houston, completing a beautiful commemorative guide to mark the 50th anniversary of one of humankind’s most remarkable achievements.

Debbie Ireland has spent 19 years working in photography, having held the positions of assistant curator of the Royal Photographic Society’s archive and head of the AA World Travel picture library.

Friday 13th July, “Blue Dots: Technology Developments on ISS for Finding Earth 2.0.” Dr Daniel Batcheldor

Event held at BRLSI. Friday 13th July, 7.30pm.

Dr Daniel Batcheldor from the Florida Institute of Technology

The last decade has seen a giant leap in the number of known planets around other stars. As we improve our technologies, and invent new ones, we have been getting better and better at finding these exoplanets. To date, we have uncovered some incredible statistics that have fundamentally changed our understanding of planetary systems; Jupiter-like planets can be close to their host stars, Earth-like planets are very common. The Kepler Space Telescope has been responsible for finding most of the known exoplanets, and the TESS mission is attempting to find the closest stars with planetary systems. These data will be used by the James Webb Space Telescope to point at those planets that might tell us something fundamental about their atmospheres. The imaging of these planets, however, is incredibly difficult and has only happened in a handful of cases. Recently, we have been testing technologies that should massively simplify future attempts to image exoplanets. We have carried out observations in Florida and on the Canary Islands, and have recently completed an ISS mission to demonstrate a key technology. During this lecture, our current understanding of exoplanets, the techniques used to detect them, and the status of our ISS mission will all be discussed.
