Hm, I don’t get this cold thingy. In what measurement this was calculated? In Celsius or Kelvin it is not possible, given they are a linear scales, (I’m not familiar with Fahrenheit, but I guess that is too, because I think we measure heat on linear scales regardless how cold or how hot it is) and as I found it on Wikipedia, liquid Nitrogen is 195.79 °C, and absolute zero, which is impossible to reach (or to exceed) is -273 °C that is 0 K and ‒459,67 °F. So this thing is on the “or not” side for me. :)
Researchers from NASA and MIT have cooled sodium gas to the lowest temperature ever recorded – one-half billionth degree above absolute zero. At absolute zero temperature (-273 degrees Celsius), all molecular motion would stop completely since the cooling process has extracted all energy from the material. The gas needed to be confined in a magnetic field; otherwise it would stick to the walls of the container and be impossible to cool down. The researchers used a similar methodology that led to the Nobel Prize for Physics in 2001with the discovery of Bose-Einstein condesates (where the molecules move together in an orderly way at low temperatures).
NASA-funded researchers at the Massachusetts Institute of Technology (MIT), Cambridge, Mass., have cooled sodium gas to the lowest temperature ever recorded, one-half-billionth degree above absolute zero. This absolute temperature is the point, where no further cooling is possible.
The Finnish experiment achieved a temperature of 0.000 000 000 1 degrees above the absolute zero. Liquid nitrogen is 77° above absolute zero. But why quibble – they only underestimated by 7600 %.
I have this problem with the wording of coldest one. You cannot have it this many times anything and have it a smaller number. Maybe ‘one trillionth’. Cold is just a lack of heat. ‘One trillionth the temperature of….’
The temperature thing isn’t worded correctly. It doesn’t make sense to say one temperature is a number of times colder than another. I think what they meant was that the created temperature was only one trillionth the temperature of liquid nitrogen. Both temperatures must be measured from absolute zero.
It is stated correctly. Being twice as cold would set the mark at 38.5°K, ten times colder at 7.7°K, hundred times colder 0.77°K, etc. A trillion times colder would set the temp at 77 / 1e12 = 0.000,000,000,077°K

But was the temperature anywhere near absolute zero ?

A trillion times; I definitely don’t believe this one.

So a trillion X −195.79 °C = <-273. How does that work?

It’s no big deal…all they did was leave the windows open.

What I want to know is how they could measure that temperature. Obviously not a mercury thermometer.
