Texas State Board of Education brought me in today to testify about #math education and curriculum! I was impressed! They brought some students to testify first, representing a range of levels in math, all the way to very high end. Board was compassionate about everyone, and…
Years ago when I visited Australia for the first time, the first Australian I went to see was Eddie Woo @misterwootube, in his natural habitat at Cherrybrook Technology High School. Last night, he gave a talk at the International #Math Olympiad, to a combined audience of…
2 @CarnegieMellon professors are at International #Math Olympiad! Yang Liu was student on USA team the first year CMU hosted training camp Yang is now USA Deputy Coach. I’m not involved with USA team anymore. I’m here for all countries, leading Reunion inviting all past players!
It is pretty amazing that Cezar Lupu's vision for a massive international #math Olympiad camp has taken off. This year, 35 countries had students present at his program, including multiple national math teams (!!!) I saw them today. I had the pleasure of getting to know him a…
🙏 mathenchant.wordpress.com/2025/06/17/rem… blogs.ams.org/matheducation/… Kelly founded the Hampshire College Summer Studies in #Math program in 1971, one of oldest math camps in USA. He influenced many people, who went on to make great contributions in math and out. en.m.wikipedia.org/wiki/Hampshire…
International Math Olympiad Alumni Reunion is open for registration: imof.co/reunion/reunio… It will be July 18–21 in Sunshine Coast, Australia. A few years ago, while I was the national coach of the USA International #Math Olympiad team, I realized it would be valuable to…
Tons and tons of food delivery bags. DoorDash culture on steroids. Super cheap in China because unfortunately there are so many people needing jobs that the drivers earn very little. And the drivers’ work enriches the company they work for, and it’s been known for years that the…
Romania's new president @NicusorDanRO is a remarkable person: #math problem-solving super-genius (two-time International Math Olympiad perfect scorer), personable and friendly, and committed to using his genius to problem-solve for society with an understanding of human nature.…
Recorded a new collaboration video with @tomrocksmaths yesterday, and also coincidentally met my Probabilistic Combinatorics professor from 20 years ago! What’s the chance of that? Then met some new acquaintances over dinner, because one of them reached out on Instagram. 😊
Just 3 mathematicians hanging out @stedmundhall. Thanks to @PoShenLoh for making the trip to Oxford - new video coming soon - and to my colleague Oliver Riordan who it turns out lectured a course in Probabilistic Combinatorics @Cambridge_Uni when Po was a graduate student there!
Spoke in the UK Parliament today (!!!) at the launch event for mathshorizons.uk, to a group of MP's, peers, #math educators, and policy thinkers. It's remarkable that in the UK, there can be a math education initiative which reaches this level, which includes teaching more…
I just made a “Mr. Po” visit at a really remarkable middle school @MalesusSTEM, in Jackson, Tennessee. The students are really clever and used to actively brainstorming in science, technology, engineering, and #math. The school’s curricular structure is unusual: students are…
Starting another urgent mission: to help bring together our polarized society. Want to help? There's a lot of room for kind and clever high schoolers to directly join in and work with me (more below). And also a lot of room for everyone else. I've been thinking a lot about the…
I've come up with a way of demystifying e (2.718) for high schoolers. poshenloh.com/e I think it is much more intuitive than how e is currently taught, and could update all of the textbooks. Full article: arxiv.org/abs/2504.10664 In the USA, the first time people learn…
Got a new library card, with a remarkable randomly generated number! Tons of books are here. I’ve been digging around lately for something. Will tell more very soon. 🙂
Oh my goodness. GPT-o1 got a perfect score on my @CarnegieMellon undergraduate #math exam, taking less than a minute to solve each problem. I freshly design non-standard problems for all of my exams, and they are open-book, open-notes. (Problems included below, with links to…
Omg I met @DrEugeniaCheng at the Museum of #Math @MoMath1 ! The first time I heard of her was from her spectacular appearance on Colbert. This is a must-see: youtu.be/mA402F5K47o I got to chat with her about the back story of that appearance. It was improvisational comedy!…
Good night! In Los Angeles for the weekend. The excuse is that @Caltech is running a big math contest for high schoolers.
