May 12 was chosen for the Celebration of Women in Mathematics because it is the birthdate of Maryam Mirzakhani. The initiative was  proposed by the Women's Committee of the Iranian Mathematical Society and voted by a vast majority of attendees to (WM)², the World Meeting for Women on Mathematics on last July 31 in Rio.

Several suggestions for local activities around May 12 are listed here.Please feel free to organize one and mention it on May 12 website.

The  Gender Gap in Science Book can be found here. It can also be ordered as a printed book through many retailers worldwide. For example on Book Repository

A booklet in several languages summarizing the results of the project and presenting its recommendations can be found here.

The book World Women in Mathematics 2018 (Proceedings of the First World Meeting for Women in Mathematics (WM)² , Vol. 20, C. Araujo, G. Benkart, C. Praeger, B. Tanbay (Eds.) was published at the end of 2019 in the Association for Women in Mathematics Series (Springer).

Marithania Silvero Casanova was not yet born when Louis Kauffman stated in 1983 the conjecture that established that two particular families of knots were equivalent. Silvero, born in Huelva in 1989, refuted the conjecture in 2015. Her finding has been recognized with the Vicent Caselles research prize, awarded by the Royal Spanish Mathematical Society and the BBVA Foundation.

In recognition of Dr. Mirzakhani’s remarkable life and achievements, the National Academy of Sciences has established a newly named Maryam Mirzakhani Prize in Mathematics (formerly the NAS Award in Mathematics, which was established in 1988 by the American Mathematical Society in honor of its centennial). The prize will be awarded biennially for exceptional contributions to the mathematical sciences by a mid-career mathematician. Nominations for the inaugural Mirzakhani Prize are due by October 7, 2019.

Carola Schönlieb has  received the 2019 Calderon Prize, which is a prize for the Inverse Problems field (awarded biennially  starting in 2007). Carola Schönlieb is the first woman mathematician that received this award, her work being in image processing and partial differential equations.

Carola Schönlieb is the current covenor of European Women in Mathematics.

Carmen Torras and Elisa Lorenzo Garcia received the Prize for Pioneer Women in the Physical, Chemical and Mathematical Sciences of the Tatiana Pérez de Guzmán el Bueno Foundation.

The awards ceremony  took place on June 4 2019 at the Spanish Royal Academy of Sciences.In this fourth edition the prize was awarded to Carme Torras (Barcelona, 1956) and for the first time the Young Modality of the Prize was awarded: the recipient was Elisa Lorenzo García (Madrid, 1987).
