Melitta BentzDiscovery of the Month

This month, we look at the story of the coffee filter, invented in 1908 by Melitta Bentz who patented her invention and launched her own company.

Competition

This month, we’ve got a signed copy of Dr Helen Czerski’s Storm in a Teacup: The Physics of Everyday Life, to give away. In this, her newest book, Helen uses physics to answer some vexing questions, such as why does it take so long for ketchup to come out of a bottle? And, how do ducks keep their feet warm when they’re walking on ice?

Storm in a TeacupTo take part in this competition, just leave a comment on our Facebook post about this episode of our podcast, and let us know which woman in STEM you most admire! Get your answer in by midnight on 30 April, and we’ll let the winner know via Facebook.

If you want to see Helen talking about her book and her work, then get yourself along to the Scarborough Book Festival at the end of April, the Hay Festival in May, and the British Humanist Association Convention in June. More details on Helen’s website!

Welcome to the Ada Lovelace Day podcast, highlighting the work of women in STEM. Each month, we talk to women from around the STEM world about their careers, as well as talking to women and men, about historic and modern women’s achievements, discoveries, and inventions.

In this episode

00:42: Computer programmer Elen Gwynne talks about how she transitioned from astrophysics to software.

20:50: Discovery (Invention!) of the Month – The Compiler

24:45: Professor Jim Al-Khalili OBE talks about the first woman to become a professor of physics in the UK, Professor Daphne Jackson.

Elen GwynneOur interviewees

Elen Gwynne

Elen Gwynne is a software programmer in London. She studied astrophysics at Edinburgh, where she was introduced to computer programming. After a programming based summer placement, she decided to take up programming as a career.

Professor Jim Al-Khalili OBE

Jim Al-KhaliliJim Al-Khalili is a theoretical nuclear physicist, author and broadcaster based at the University of Surrey in England. He received his PhD in nuclear reaction theory in 1989 and has published over a hundred research papers in the field. He is a well-known presenter of TV and radio in Britain and his many popular science books have been translated into 26 languages. He is a recipient of the Royal Society of London’s Michael Faraday medal and the Institute of Physics Kelvin Medal. In 2016 he received the inaugural Stephen Hawking medal for science communication. He lives in Southsea in Hampshire with his wife Julie.

Jim has two new books out, Aliens: Science Asks: Is There Anyone Out There? and Quantum Mechanics (A Ladybird Expert Book), and you can listen to him interview a wide variety of women (and men!) in STEM in The Life Scientific on BBC Radio Four.

You can find out more about Jim on his website or Wikipedia, and can follow him at Twitter @jimalkhalili.

If you’d like to to know more about Professor Daphne Jackson you can take a look at her Wikipedia page, and if you’re a woman in STEM thinking about returning, take a look at the Daphne Jackson Trust website.

Discovery of the Month

More of an invention than a discovery, the first compiler was written in 1951 by mathematician and programmer Grace Hopper, who would go on to become a Rear Admiral in the US Navy. She also suggested as early as 1949 that computer programming languages might use English keywords.

You can read an imagined conversation with Hopper on the Libertine website.

She is the author of the popular science book The Memory Illusion, which was published in June 2016, in the UK and will soon appear in 13 languages. She is a regular contributor to Scientific American, and her work has been featured in outlets such as the Discovery Channel, BBC, Der Spiegel, Russia Today and The Times.

Besides her teaching and research, she has delivered general business and police training workshops, has given guest lectures at universities around the world, has evaluated offender diversion programs, and works with the UK police to advise on historical sexual and physical abuse cases.

Julia has also written about women in STEM for the Scientific American, in Swapping Princesses and Ponies for Science. You can follow Julia on Twitter at @DrJuliaShaw, and watch her video on memory below or on YouTube. Photo: Boris Breuer

Dr Brenna Hassett

Dr Brenna HassettDr Brenna Hassett is a bioarchaeologist specialising in the archaeology of teeth. Her research examines evidence from growth disruptions locked inside dental enamel to understand patterns of human health in the past, and she has worked in a variety of countries including Egypt, Greece, Turkey, and Thailand.

She is a founding member of the TrowelBlazers collective, which seeks to reset imaginations by bringing the contributions of women to the Earth Sciences to light. Their new Raising Horizons project will promote the work of women in the trowel-based sciences via a photographic and oral history archive (video below).

Her new book Built on Bones: 15,000 Years of Urban Life and Death is out from Bloomsbury Sigma in the UK in February 2017, and in North American April 2017. You can follow Brenna on Twitter at @brennawalks.
