== Reaching Absolute Zero ==
It's not really possible to achieve absolute Zero, but scientists have come quite close. The first example of this occured in [[1908]] when [[Kammerlingh Onnes]] liquified [[Helium]]. The temperature he reached was approximately four Kelivn. Lower temperatures have been reached with different [[isotope|isotopes]] of Helium. A temperature of 0.3 Kelvin has been reached with <sup>3</sup>He. The lowest temperature ever reached by any substance was 280 picoKelvin.
