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 ...

Physicists don’t tend to use universal language freely, so since Lord Kelvin dubbed the base measure of his temperature scale “absolute zero,” that should be a sign that there is reason for the ...

Researchers from four universities in Germany have conditioned a lab to register the coldest effective temperature in a research-controlled environment ever recorded—38 trillionths of a Kelvin above ...

THERE is no upper limit to the temperatures which could conceivably be reached; in marked contrast to this, there is on the low temperature side a sharp boundary at -273-1° C.—the absolute zero of ...
