I've talked before about meeting other professionals in the industry and trying to learn different techniques in developing a perfect roast. Today I cracked open some old textbooks from my undergrad days as a Mechanical Engineer. The book talks about Thermal Conductivity, Heat of Evaporations, Convection, Radiation, etc. It's fun getting into the weeds sometimes. By understanding the process better we hope to bring finesse to the process. In today's enrivonment, if you aren't improving, you are getting stale.
