History

(Gr. neos, new) Discovered by Ramsay and Travers in 1898. Neon is a rare gaseouselement present in the atmosphere to the extent of 1 part in 65,000 of air. It is obtainedby liquefaction of air and separated from the other gases by fractional distillation.

Science Quote

'The strength and weakness of physicists is that we believe in what we can measure. And if we can't measure it, then we say it probably doesn't exist. And that closes us off to an enormous amount of phenomena that we may not be able to measure because they only happened once. For example, the Big Bang. ... That's one reason why they scoffed at higher dimensions for so many years. Now we realize that there's no alternative... '
