Did you know?
- The Proto-Indo-European root of wissen actually meant 'to see', suggesting that ancient people conceptually linked the act of seeing with the act of knowing.
- In German, the word Wissen used as a noun refers to 'knowledge' in a general sense, but it is also the root of Wissenschaft, which means 'science'.
