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 ...
In a new publication, Professor José-María Martín-Olalla, from the Department of Condensed Matter Physics at the University of Seville, has described the direct link between the vanishing of specific ...
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 ...
A 19th-century thought experiment has turned into a real technique for reaching ultralow temperatures, paving the way to new scientific discoveries as well as to useful applications As you read these ...
