내가 너무 옹졸한 것 같기도 하면서도… 한편으로는 나는 다른사람한테 수학을 가르쳐줄 때 저런 사족을 무심코 뱉지 안도록 주의해야겠다고 다짐하게 된더

뭔가 내가 막혀서 거민하던 걸 물러봤을 때 알려주면서 ‘쉽네ㅋㅋ’ ‘그냥 정의로 되네ㅋㅋ’ ‘고등학교 수핫이네’라는 사족을 항상 붙이는 친구가 있다. 틀린 말이 아니고, 내가 쉬운 부분에서ㅜ막혔던 것도 팩트지만, 왠지 모르게 기분이 나쁘고 별로 이 친구한테 물어보기 싫어진다

It's a misconception that the Yoneda lemma is about categories (hence the whole philosophical craze surrounding it) -- in fact it works perfectly well for (fin. dim.) Hilbert spaces already : if (H, <-,->) is such a space, φ ∈ H* and v ∈ H, then

Sheaf, sheafification, sheaf의 inverse image와 direct image… 분명 대수기하를 공부하랴먄 알아야 하는 기본적인 내용인 것 같은데, 처암 공부하는 입장에서는 봐도봐도 낯설어….ㅠㅠ… 으 언젠가는 군, 환, 위상공간처럼 자연스럽게 다룰 수 있게 되려나

몇년 지난 것이긴 한데, TikZ 코드 HTML 코드에 그냥 써놓으면 자바스크립트로 돌려서 웹페이지에서 그림을 만들어서 보여주는 javascript 코드가 있었군요. TeX engine의 Pascal 코드가 javascript에서 돌아가도록 포팅도 되어있었다니… github.com/kisonecat/tikz…
지금 현행 중등교육과정의 마지막 대수학 내용이 다항식의 나머지 정리인 것이 매우 안타깝다 (고급수학에 있는건 사실상 교육과정에 유의미하게 남아있다 할 수 없음)
