== Reaching Towards Absolute Zero ==
== Reaching Towards Absolute Zero ==
It is considered theoretically impossible to achieve absolute Zero, but scientists have come quite close. The first example of this occurred in [[1908]] when [[Kammerlingh Onnes]] liquefied [[Helium]]. The temperature he reached was approximately four kelvins. Lower temperatures have been reached with different [[isotope|isotopes]] of Helium. A temperature of 0.3 kelvins has been reached with <sup>3</sup>He. The lowest temperature ever reached by any substance was 280 picokelvins.
