Curiosity, in small doses.

youknowwhy.co started as an Instagram page for the questions that pop into your head and then quietly disappear. Why is the sky blue? Why do cats purr? We write the answers down before they escape.

Every post follows one rule: one question, one honest answer, no filler. If science doesn't know yet, we say so.

This site is the archive the same posts, easier to read, search and share.
