Cook your turkey, with calculus

Reminder: If you check your Turkey’s temp at two points while it bakes, then Newton’s Law of Cooling can tell you what time your turkey will reach 165°.

Here’s a pic from 2013 when my math grad school friends and I did the calculation. It predicted 6:30 and was almost perfect. pic.twitter.com/KpOoAYwp2l
