Buckets of Fish! I love Buckets of Fish!!! So nostalgia. It was the first game we ever played in intro to proofs in undergrad <3 <3 <3 (My professor presumably learned it directly from JDH who was his advisor)

Math is in crisis. The NSF claims the over $80M in cuts is due to "changing priorities" but when asked how math fits to their new priorities they said it is "required to advance future discoveries in every critical technology area." What gives??? www.scientificamerican.com/article/can-...

A 72 percent reduction in federal funding is devastating to math research. The American Mathematical Society is offering $1 million in backstop grants—but it’s likely not enough.
