I had a professor for Thermodynamics as an undergrad in night school. He was semi-retired, but working as a consultant on an artificial hear in the mid-80s. Fascinating when he digressed into the practical engineering problems of developing a reliable heart that would act as a bridge until a donor heart would become available. I always tried to imagine a cardiac surgeon attempting to converse with a mechanical engineer... 2 different languages.
In case it’s not self evident, I’m an engineer. Once I worked on a company developing an intravascular implantable defibrillator. There was a well-known M.D. involved in the company. He’d come to our technical meetings and just sat there looking confused. In my head, I referred to him as the “installation technician” because he was working with things he didn’t understand.
