When many quantum particles interact, complex systems can be formed. And this complexity allows reaching a temperature of absolute zero—at least in principle. The absolute lowest temperature possible ...
The absolute lowest temperature possible is -273.15 degrees Celsius. It is never possible to cool any object exactly to this temperature – one can only approach absolute zero. This is the third law of ...
TO IMAGINE working your way down the temperature scale into the realms of extreme cold, you might start with the inside of an industrial freezer. At about -18°C (0°F), it is uncomfortable, but ...
