Phys.org / Heat has a memory—and a new theoretical framework can track it

Heat, it turns out, has a memory. A cooling cup of coffee may not seem particularly thoughtful. At the scale of a kitchen, heat appears to follow a straightforward rule: it moves from warmer places to cooler ones. Leave the ...
