Yes, you read that right.
The words science and shit are actually related.
They both belong to a very large family of words that has at its core the idea of shedding, separating.
The original idea behind science is the idea that you discern (another family member) things from one another. And I think we all know how the word shit ties in with the core theme.
In German, there are lots of words in that family too, with the most famous probably being der Unterschied (the difference), unterscheiden (to discern, to differentiate) and verschieden (different).
