What the money paid for, in its own words
FY2025 · Form 990, Part III · the three largest programs by expenseScientific programs: slmath conducts broadly-based research programs in the Mathematical Sciences and closely related fields. In any given year, slmath conducts between two and four thematic research programs, each lasting either 5 months or 10 months. Each such program hosts 60-120 mathematical scientists from all over the world whose research centers on the program's theme, during which time they collaborate on research, conduct seminars and workshops, and train and mentor postdoctoral fellows in the discipline. Slmath also hosts, each year, several stand-alone workshops on special topics…
Computing and communication: slmath provides information technology (it) resources and services to its researchers and the broader math community worldwide. Slmath maintains an it platform that features the most advanced mathematical software and that grants access to and supports virtual collaborative research amongst mathematicians at the institute. Slmath develops and maintains a vmath website that streams videos of past program lectures for mathematicians and the general public. In addition, slmath produces and distributes digital versions of its most popular scientific and public events
Math and society programs: slmath sponsors a number of programs and activities with the goals to enhance both k-12 mathematics education and the public understanding of and appreciation for mathematics.these programs include supporting the bay area mathematics olympiad (bamo, a mathematics-related event for students in grade 12 or under), the mathical book prize (an annual award for fiction and nonfiction books that inspire children pre-k - 12 to see math in the world around them), two book distribution programs (which provide mathical prize-winning books to title I schools nationally and in…
