Hypothetical—if you were forced to go get a PhD in one of the following science fields, which would it be and why?

1. Physics
2. Chemistry
3. Biology

Working on Farcaster and Warpcast. Longer thoughts at https://dwr.email

2.
I'm already degree'd in electrical engineering and most physics (spare cosmology) is indistinguishable from the EE dept.

Re. 3: I was originally pursuing neuroscience as a field in grad school, but I saw enough bio to not be enamored with studying a single protein or pathway for 5 years.

Chem is practical
