On Poisson Disk Sampling | Stripe Across

💥 Check out this trending post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: In 2024, a team of nine mathematicians released a monstrous, nearly 1,000 page proof of the geometric Langlands conjecture.

Three schoolgirls in Kinsale pulled up a pea plant covered in warts and, instead of binning it, spent three years testing 13,000 seeds in a spare bedroom — the bacteria living in those warts made barley germinate 50% faster, and the adults who said it wouldn’t work on cereals watched them take Google’s grand prize

Émer Hickey was gardening with her mother in Kinsale, on the Cork coast of Ireland, when they pulled up a pea plant and found its roots studded with pale, wart-like lumps. It looked sick. Émer, then in her early teens, did the thing that separates a science story from a compost story: she took the plant to school and asked her teacher what was wrong with it. Nothing, was the answer. The warts were nodules, and inside…
