Regular Live Streams

(Excerpts from Weekly Show)

For several years Po-Shen Loh routinely traveled the country (and world) on a weekly basis, giving math talks in different cities to increase interest and ability in math. When COVID-19 (the coronavirus) made it difficult to host in-person events, he launched a free weekly YouTube Live math show in early 2020. In response to sudden school closures, he started running the free daily YouTube Live stream Ask Math Anything, with Po-Shen Loh on Mon Mar 16, in which he interactively answers math questions asked in real-time via YouTube Live. All upcoming sessions will be announced here on this page, with automatic notifications sent to subscribers to the Official YouTube Channel of the Daily Challenge with Po-Shen Loh.

Due to YouTube's legal restrictions regarding real-time chat, active participation in all live streams is meant for people 13 years of age or older.

This button to join the active live stream will be updated 15 minutes before the stream start time, and all streams will also appear at that time on our Official YouTube Channel.

Carnegie Mellon University Putnam Seminar

Due to the COVID-19 pandemic, Carnegie Mellon University is protecting the health and safety of its community by holding all large classes online. This semester, Prof. Loh is teaching the Putnam Seminar, which is a university-level course that develops creative problem solving skills while taking a whirlwind tour of math subjects. It is taught in a student-driven way, where the class brainstorms together to solve very difficult math problems. The official course website is here.

To make it easier for students in different time zones to view the course, the beginner section of this course will be shared and preserved online each week. People from outside Carnegie Mellon University are welcome to tune in to see how the class is taught, but unfortunately Prof. Loh will not be observing or responding to the real-time comments in YouTube. He will be responding to the students participating in the private Carnegie Mellon University Zoom chat.

Show Times.
Fridays 5:20 – 6:10pm Eastern Time, starting Fri Sep 4.

Daily: Ask Math Anything, with Po-Shen Loh

In each 60-minute weekday live stream, Po-Shen Loh invites students, teachers, parents, and anyone interested in math to post math questions in the YouTube Live interactive chat. He will improvise mini-lessons around them, showing how mathematical reasoning is interconnected, and how learning to think creatively about math can actually simplify the task of learning math itself. He gives preference to questions in Algebra 1, Geometry, and Algebra 2, as they are the gateways to mathematical fluency.

Format. This stream is intentionally friendly and informal. Po-Shen Loh will pick out the most mathematically interesting questions in the chat in real time, and interact with the audience. None of the mini-lessons will be prepared in advance, to give the session a more lively feel.

This show ran every weekday from Monday March 16 – Friday July 3. In July, the show reduced its frequency due to Po-Shen Loh organizing the USA Math Olympiad Program, which ran that month. Unfortunately, the show has ended due to a refocus of efforts on fighting COVID.
