Charles Petzold's other book, The Annotated Turing is also a great read.
"In a famous 1907 paper on relativity, Hilbert's friend Hermann Minkowski would coin the word Zaumreit or spacetime."
Zaumreit literally translates to "bridle riding" and is probably a play on words, Raumzeit means spacetime. This has puzzled me for over a decade now. How does this even happen?
I'm guessing the author remembered the word incorrectly and wrote it down that way. It's not hard to transpose two letters when you don't know the language.
