Time for a baby name battle!
First off, yes: Petrichor and Tesseract have both been used as baby names in real life! I found a baby girl named Petrichor in the 2016 Alberta data, and a baby girl named Tesseract in 2017 Quebec data.
Both names are unusual, both names are geeky, and both names can be shortened (e.g., Petra, Tessa) to make them easier to use day-to-day.
So…if you were having a daughter, and you had to name her either Petrichor or Tesseract, which would it be? Why?
