From the field
The same lessons come up again and again from people actually doing the job:
People think I'm a chemist in a lab. I'm an engineer — I take a reaction that works in a beaker and design the factory that makes it by the tonne, safely and efficiently. Scale-up is a whole discipline, and it's fascinating.
