In We Need to Talk About Kelvin, Marcus Chown (a consultant for New Scientist) shows us how things we experience every day can reveal profound truths about the nature of reality.

So now if I put sugar in the water, and I follow my diagram here, what I find is that the new melting point of water T1 is some new temperature T, T1, where T1 is less than 273 degrees Kelvin.

The experiments were conducted in an ultra-high vacuum at the low temperature of 10 Kelvin, with the use of liquid helium.

"The stability against freezing of Martian fluids can explain saline water activity on the surface of Mars at mean global temperatures well below 273 Kelvin," they wrote.

To provide sharp contrast in workspaces and under reading lamps, buy a CFL labeled "daylight, " or with a higher Kelvin temperature.
