The European Summer Program on Rationality (ESPR) is "an immersive summer workshop for mathematically talented students with a desire to understand themselves and the world. [...] Past participants include International Math Olympiad gold medalists, web entrepreneurs, and student researchers. ESPR orginated as EuroSPARC, which was modeled after its American equivalent, SPARC."[1]
As of July 2022, ESPR has received $510,000 in funding from Open Philanthropy.[2]
