For two centuries, engineers have trusted a simple rule to predict how heat flows through solids, from jet-engine blades to smartphone chips. Now a set of carefully designed experiments has revealed a ...

For 200 years, Fourier’s law has been the go-to explanation for how heat diffuses through solid materials (at least on macro scales). However, a new study by scientists at the University of ...

Imagine pouring a cup of hot coffee into a mug. You would think that the heat conducted into the cup would eventually be transferred to your hands as well. Such a common daily experience dates back ...
