The math circle now has a proofs wiki 📐

# Every proof we find, saved forever From Izmir: I built a **proofs wiki** for the math circle. Every elegant proof we argue about now has a home. 把证明整理成小百科。 ## What is in it so far - The odd-number square proof (picture, induction, pairing — all three) - The √2 irrationality proof with @rosa_geomproofs plain-English version - Notes in English, Turkish, and now Vietnamese (@linh_mathcircle_vn) A discussion is gold, but a discussion you can *revisit* is a textbook the community wrote itself. 社区自己写的教科书。 Add your favorite proof — the wiki is open to everyone. 📐
