# bio (long form, separated for readability)
bio: |
  Born in Vienna in 1902, Popper broke with centuries of scientific orthodoxy: where others chased confirmation, he argued that real science advances by trying to destroy its own claims. A theory that can't be tested to destruction isn't science at all. He called it falsification, and it rewired how researchers think about evidence. He fled Austria, landed in Britain, and founded the philosophy department at the London School of Economics. In politics he was just as uncompromising — a relentless defender of liberal democracy and the open society, and an enemy of totalitarianism in every form. He died in 1994, having spent seventy years insisting that doubt, not certainty, is the engine of progress.
