# Math Jams

Math Jams are free online discussions hosted by Art of Problem Solving for a variety of purposes, including:

- Informational sessions about Art of Problem Solving classes.
- Review of the AMC and AIME competitions.
- Introductions to new topics in math and other areas of study.
- Special events, such as our annual discussions with admissions officers and professors from outstanding universities such as MIT, Carnegie Mellon, Stanford, and Duke.

To attend a Math Jam, simply sign in to Art of Problem Solving just before the Math Jam begins, and click on the Classroom bar that will appear on the screen. The Math Jam classroom will open 10 minutes before the Math Jam begins. (See Classroom System Requirements)

Our Math Jams are held in the same online classroom as our online courses. Click here to read more about how our online classroom works.

Participants in Math Jams must be signed in as Art of Problem Solving Community members to access the Math Jams.

. The Math Jams and Community membership are free.Join our mailing list to receive announcements about new Math Jams.

### USAMTS Round 1 Math Jam

### NOVID: Using Math to fight COVID

Instructor: Po-Shen LohDifficulty Level: 1* (Introductory math)

7:30 pm ET

COVID ruined 2020, but math can help! Do you want to help to bring your part of the world back towards normalcy? Math teams around the country are helping to develop a completely new approach to contact tracing to help make school reopening safer, using graph theory. Po-Shen Loh will talk about the NOVID app, which acts like a "COVID radar." For each positive case, instead of just asking the direct contacts to quarantine, NOVID tells everyone how many relationships away the case was (so "2" is a contact of a contact). This lets people actively avoid getting sick. This session will be an Ask-Me-Anything style interactive discussion about how this math-powered system works, so that interested students can have the understanding to bring this innovation to their communities.
