«Several people have asked if there will be a Summer of Math Exposition this year. Although we will not do a full SoME4 with a winner selection and prizes, there will be a more casual community-driven version, which people have given the delightful name SoMEπ.

People are still encouraged to try their hand at making a piece of math exposition this summer, whether a video or a written piece, and there will be a deadline to encourage completion, August 18th at 11:59 PM (UTC-12). After this, there will be a similar peer review process to past years, ensuring people receive feedback on their work. Past years have demonstrated how this process also has the wonderful side effect of kickstarting viewership on the video entries, giving the YouTube algorithm a chance to learn cowatching behavior between all of them.

The primary difference from past years is no final selection process for winners and no prizes.»
