In physics, chilling out isn’t as simple as it seems. A hot object can cool more quickly than a warm one, a new study finds. When chilled, a warmer system cooled off in less time than it took a cooler ...

The story goes that in 1963, Tanzanian high school student Erasto Mpemba was making ice cream with his class when he impatiently put his sugar and milk concoction into the ice cream churner when it ...

Decades after a Tanzanian teenager initiated study of the “Mpemba effect,” the effort to confirm or refute it is leading physicists toward new theories about how substances relax to equilibrium. It ...

It sounds like one of the easiest experiments possible: Take two cups of water: one hot, one cold. Place both in a freezer and note which one freezes first. Common sense suggests that the colder water ...

Humans can hear the difference between hot and cold water when poured. In an experiment, scientists found that a deep neural network computer program could learn to tell the difference, too. This ...

Does hot water really freeze faster than cold? Jennifer Ouellette describes what could be a new theoretical understanding for the so-called Mpemba effect – and why it predicts that cold water could ...
