Someone in this picture is defying gravity. Spent the day at MathCON where our youngest daughter participated in the 4th grade category. I think this is a great event. They drew 600+ students to come together, many from all over the country, and the day was full of positive

I learned about an incredible school today: GSSM South Carolina Governor's School for Science + Math! And then I discovered to great surprise that one of my elementary school classmates Alexander Wille teaches Chinese there!!! I spent the afternoon at GSSM, talking to

I met Sally Tsang (Zhao) at the International #Math Olympiad in 2001 in Washington, DC, when she was on the Australian national team. I was still in college at that time, and I was a tour guide. (Of my roles at the IMO thus far, "guide" has been the most fun.) Today we met up for

Spent a week in Melbourne and Sydney, thanks to University of Sydney Mathematical Research Institute (SMRI). It was really refreshing to meet a lot of authentically curious and interesting students. It was lovely. The ecosystem in Australia is that math competitions do not factor into

2024 IMO Alumni Reunion applications now open, for 50 spots! It will be July 20–23, in Bath (IMO 2024), Blenheim Palace, Oxford, Bletchley Park, and Cambridge: imof.co/reunion/reunio… If you work with #math Olympiad students/alumni, please share with them, as they may wish to

Just finished running the USA Math Olympiad camp for one final time, last night. So I’m back on the road with the show. En route to NYC this morning, to speak at Columbia University Business School. I never thought I’d end up there as a #math person… then on to Wyoming by nightfall. Maybe

I caught up with an old classmate Tyson Mao when visiting Stanford University University Mathematics Camp today, after I heard Rick mention that Tyson was coming as a guest speaker this weekend. Tyson is crazy good at the cube. en.m.wikipedia.org/wiki/Tyson_Mao ~20 years ago, we were both at

Great to see you! We were neighbors when we both were studying math at Caltech, about 20 years ago. Very interesting to approximately intersect over and over again, both in location and in interests!

This is a real en.m.wikipedia.org/wiki/Enigma_ma… and it’s the same physical one that appeared in the movie featuring en.m.wikipedia.org/wiki/Bletchley…. Visiting with the International #Math Olympiad Alumni Reunion imof.co/reunion

Caught up with Jordan Jordan Boyd-Graber yesterday, while passing through Univ. of Maryland. He's been using #NeuralNetworks to answer Quizbowl-style questions long before most of us heard about #GPT. Along the way, they even beat Ken Jennings (colorado.edu/cs/2015/10/20/…). Now, his research

Thank you so much for your support! I have been deeply inspired by my colleagues at Carnegie Mellon University, who led by example. They think big.

Omg! The volunteer running the A/V for my talk in Cupertino turned out to be none other than Larry Wall, the CREATOR OF PERL!!! I wrote so many #Perl scripts. I loved $_ as a concept. The USA national math Olympiad training program schedule was generated with the help of a Perl

Caught up with old acquaintances while in the Bay Area. The last time I ran into Ralph Furman was on the beaches of Colombia, when he was the national coach of the Canadian IMO team, and I was the deputy coach of USA. Now he’s built quite a company (Parafin), which has
