One ten-billionth K

  1. Oct 29, 2003 #1
    I was reading Discover (November 2003), on pg 18 Ask Discover, it says "Absolute zero cannot be reahed experimenally, but scientsts have cooled small samlples of atoms to just one ten-billionth of a degree above absolute zero."

    How could scietists cool the sample to such a low temperature ?

    Hey KL :wink:

    LASER Cooling



    A note on Chu; I saw him a few years ago at Stanford. He spoke for quite some time about the importance of encouraging imaginative thinking.

    Thanks Ivan.

    PS. I was in a hurry and didn't notice those spelling mistakes in the first post.
