6 questions, easy to hard, then Ivy's pick. Here is every answer, and why.

Answer: Alexander Fleming. He noticed mould killing bacteria on a petri dish he had left out over his holiday. Mass production only came in the 1940s, thanks to Florey and Chain, who shared his Nobel Prize.

Answer: Schrödinger's cat. Schrödinger meant it as a reductio ad absurdum, mocking the idea that quantum superposition applies to big things. The internet took it literally.

Answer: Astronomer. Both words have ten letters and the same multiset of letters, which makes it one of the rare anagrams whose meaning matches the original. 'Eleven plus two' and 'twelve plus one' is another.

Answer: True. The name means 'three stars'. It moved into electronics only in 1969 and its group now accounts for roughly a fifth of South Korea's exports.

Answer: Robert Frost. Often read as a hymn to individualism, but Frost called it a joke about a friend who agonised over every walk. The two roads were 'really about the same'.

Answer: Kodak. A Kodak engineer built the first digital camera in 1975; management shelved it to protect film. Kodak filed for bankruptcy in 2012.
