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 ...

In a new Nature Communications study, scientists have demonstrated the quantum version of the strong Mpemba effect (sME) in a ...

The Mpemba effect is an intriguing physical phenomenon that causes some systems to cool faster when they are hot than when ...

Then the experiment #3 proceeds to demonstrate mpemba effect on water that froze through the frost in the fridge. Then the experiment #8 had shown that if you use different waters, you can make mpemba ...

Heating up Physicists have shown that a colder trapped-ion qubit can warm-up faster than a hotter qubit. (Courtesy: Shutterstock/Evgenia-Fux) The inverse Mpemba ...

The question I have is - under which conditions would you say that the experiment shows the reasoning wrong, instead of experiment itself having been 'done wrong'? For example - if you do something as ...

Why does hot water sometimes freeze faster than cold? This counterintuitive phenomenon, known as the Mpemba effect, has intrigued scientists for decades. In the classical world, it challenges common ...

Not every scoop of ice cream can be described as “fateful.” But a batch of ice cream Erasto Mpemba made as a teenager in Tanzania in 1963 made waves in physics that are still being felt nearly 60 ...

A common chemical process may explain a bizarre property of water that has been a mystery since the time of Aristotle ¨C how hot water can freeze more quickly than cold. This strange and ...

Recent advances have significantly deepened our understanding of how systems evolve when driven far from equilibrium. Non-equilibrium thermodynamics examines energy flows, dissipation and entropy ...
