Olalla, from the Department of Condensed Matter Physics at the University of Seville, has described the direct link between ...

Right now, as I type this sentence, Earth’s Northern Hemisphere is tilted away from the bright ball of light that is the Sun, and it’s cold here (relatively speaking). Humans have long recorded and ...

According to the third law of thermodynamics, the entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 kelvin). When you purchase through links on our ...

When you think about the temperatures associated with “cold,” you probably imagine a cold winter day, or a block of ice (32 °F, 0 °C, or 273.15 K). This is downright balmy compared to the nanokelvin ...

Nothing is colder than absolute zero, so it seems nonsensical to talk about negative temperature – but now there is a substance that must have just that. The revelation could shake up our ideas about ...

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of ...

There’s a whole mirror world of negative temperatures reaching from minus infinity to absolute zero – now we’re plumbing those depths for real DEFINING a temperature scale is easy. Fire is hot, ice is ...
