Personal

A few years ago, in occassion of an International Women's Day, I decided to make myself a t-shirt saying "Do Maths like a Girl" (in the style of those images of heroines from videogames saying "Fight like a Girl") starring my favourite mathematicians. Since then, a lot of people have asked me where I had gotten it, and if they could use the design. For that reason, I have decided to put the file online, so that everyone can use it freely. Do whatever you want with it: change it, make copies, add your own idols, make it yours. Those women deserve more recognition. I would only ask you not to make a profit out of it. Also, if you want, you could send me a picture of the result: I would love to see it!

Who are they?

• Emmy Noether (23 March 1882 – 14 April 1935). A German Jew who flew to the United States after the rise to power of the Nazis, she's been incredibly influential not only in the field of Abract Algebra (Noetherian rings, Noetherian relations...), but also in theoretical physics (Noether's first theorem).
• Maryam Mirzakhani (12 May 1977 – 14 July 2017). Iranian mathematician based in the United States, she's still the only woman to have ever recieved a Fields Medal (2014).
• Sofia Kovalevskaya (3 January 1850 - 29 January 1891). Russian mathematician, and Weiestrass' student (in private, as women couldn't go to university at the time), she was the first woman appointed to a full professorship in Northern Europe, at the University of Stockholm (1889).
• Ada Lovelace (née Byron) (10 December 1815 – 27 November 1852). This English lady is considered to be the first person to ever write a computer program. For more information about her, here you have a short video about her life and work.
• Sophie Germain (1 April 1776 – 27 June 1831). Born not long before the French Revolution, this mathematician did her studies at the renowned École Polytechnique, in Paris, under the pseudonym of old student and family friend Auguste Le Blanc. Lagrange's student and close collaborator of Gauss (both before and after they realised she wasn't a man), she firstly worked on Fermat's Last Theorem, where she did what has been considered "the biggest advance since half a century". She then worked for a while on elastic surfaces. She was the first woman (apart from other members' wives) authorized to go to sessions of the Institut de France.
• Alicia Boole (8 June 1860 – 17 December 1940). This self-taught Irish-English mathematician, daughter of George Boole (the inventor of Boole algebras), is mostly known for her contributions to the classification and study of projections to three dimensions of polytopes in four dimensions.
• Joan Clarke, MBE (24 June 1917 – 4 September 1996). This English cryptanalyst is mostly known for her work as a code-breaker for the Nazi machine Enigma, during Second World War. Recruited by her undergraduate supervisor during her studies in Mathematics at the university of Cambridge, she became adjoint responsable of Hut 8, along Alan Turing. Despite the fact that she only spoke English, she was registered and payed as a linguist, because it was not possible at the time to have female cryptanalists. (And yes, she's the same person that gets recruited because "she's good at newspapers crosswords" in the Imitation Game film).

• Spiked Math. A webcomic consisting mostly on mathematical puns.
• PhD Comics.: Another webcomic, this one following the lives of a group of post-docs and PhD students. Worringly relatable.
• Saturday Morning Breakfast Cereal: In this webcomic there's a bit of everything, from philosophy to dark humour, but the comic strips about maths are quite on point.
• Logicomix, by Apostolos Doxiadis, Christos H. Papadimitriou et al.: A graphic novel that explains, in a very enjoyable manner, the history of the developement of Mathematical Logic at the begginning of the XXth century.
• The Number Devil, by Hans Magnus Enzensberger.: This is an educational, but very fun book about mathematics. It is a kid's book, but the complexity of the subjects treated increases as we go along, starting with exponentials and ending with cardinality, Pascal's triangle, complex numbers or even an intuition of what proofs are.
