YPMD III July 14–18, 7 * 17 * 17

We will be frequently updating this site. Check back often as more information is available.

Recently updated: FAQ for YPMD III. You can now officially register and pay by going to our YPMD III registration form.


You probably remember having left Hampshire College during one of the past 51 Augustses believing, correctly, we believe,  that you had forged one or more lifelong friendships. Please confirm our mutual beliefs by sending seasonal wishes for joy to one or more of those friends, along with the hope that you’ll see them at

Yellow Pig Math Days III, July 15, 16, 17, and 18, 17*7*17.

There will be wonderful HCSSiM alums from many—let’s make it all—Hampshire summers; and you’ve had fun thinking, playing, doing math, and sharing some life-changing experiences with them. The students and staff of the 51st Summer Studies will also be around; if you know of good candidates, please let them and us know.

This YPMDIII page will be updated regularly to announce exciting activities and speakers, to ask for contributed talks, to program a concert, and to list attendees. Also, at this website and during YPMDIII we’ll do some looking forward to HCSSiM’s next heptadecade(s).

If you are not yet ready to register, you can, for a while longer, still go to the 0-commitment-interest-indicating form ; estimated probabilities are fine.  

We need plausible attendance predictions to reserve rooms, to plan meals and budgets, and to seek foundation and corporate support for honoraria, travel expenses, financial aid, coffee breaks, a meal or two, a conference compendium, filming, swag, ice cream, … (Are you or do you know a possible source for such support?)

We hope to see you in July.
