Tadashi Tokieda (Japanese: 時枝正; born 1968) is a Japanese mathematician, working in mathematics and physics. He is a professor of mathematics at Stanford University; previously he was a fellow and Director of Studies of Mathematics at Trinity Hall, Cambridge. He is also very active in inventing, collecting, and studying toys that uniquely reveal and explore real-world surprises of mathematics and physics. In comparison with most mathematicians, he had an unusual path in life: he started as a painter, and then became a classical philologist, before switching to mathematics. Tokieda is considered a creative and fun person, giving excellent talks and explanations where he shows and teaches mathematical concepts in a simple, entertaining and beautiful way.

Life and career[edit]

Tokieda was born in Tokyo and initially intended to be a painter.[3] He then studied at Lycée Sainte-Marie Grand Lebrun[2] in France as a classical philologist. According to his personal homepage, he taught himself basic mathematics from Russian collections of problems.

He is a 1989 classics graduate from Sophia University[2] in Tokyo and has a 1991 bachelor's degree from Oxford in mathematics (where he studied as a British Council Fellow). He obtained his PhD at Princeton in 1996 under the supervision of William Browder.[4]

Tokieda joined the University of Illinois at Urbana Champaign as a J. L. Doob Research Assistant Professor for the 1997 academic year.[5]

He has been involved in the African Institute for Mathematical Sciences since its beginning in 2003.

In 2004, he was elected a Fellow of Trinity Hall, where he became the Director of Studies in Mathematics and the Stephan and Thomas Körner Fellow.[6][7]

He was the William and Flora Hewlett Foundation Fellow in 2013–2014 at the Radcliffe Institute for Advanced Study at Harvard University.[8]

In the academic year 2015–2016 he was the Poincaré Distinguished Visiting Professor at Stanford.[9]

Besides his native language Japanese, he is also fluent in French and English. In addition, he knows ancient Greek, Latin, classical Chinese, Finnish, Spanish, Russian as well as countless others. When asked how many languages he knows, he declared "the question is meaningless, it is like asking how many friends one has."[10] So far he has lived in eight countries.[11]

In March 2020, Tokieda was interviewed on The Joy of X, Steven Strogatz's podcast for Quanta Magazine.[12]
