Please don’t be shocked, but yes this is arleady the second post about a book in kind a short time (at least for normal Sascha-like behaviour)…
The Encyclopedia of the Unknowingness, unfortunately only available in German (“Lexikon des Unwissens”) so far, tries to describe several of today’s unsolved miracles.
It gives an introduction to subjects like the lifecycle of eels, dark matter, yawning, ball-lightnings, the functionality of sticky tape, the Riemann hypothesis, and many more…
A bit too many “funny” comments in my opinion though… otherwise very interesting!
