We had this cool apparatus call a Toepler pump which is essentially a glass-contained mercury piston pump. I used it to collect and measure non-condensible gases.<br /><br />Xenon is another hoot. You can fill a balloon with the stuff and it looks normal but when you toss it to a friend it has obvious heft.<br /><br />The other day I tweeted a link about that Michigan teenager David Hahn who collected elements, including the radioactive ones. <a href="http://bit.ly/149iDV" rel="nofollow">Link</a>.chickelithttps://www.blogger.com/profile/10773887469972534979noreply@blogger.comtag:blogger.com,1999:blog-6130126685334700207.post-26454426352209424362009-07-16T06:47:05.068-07:002009-07-16T06:47:05.068-07:00I love helium.

Independent discovery is much more common. First to discover is analogous to first to invent and depends on who took and kept the best records. The US Patent office has procedures and protocols in place to determine first to invent in cases of competing claims. It's relatively rare, but it does occur.chickelithttps://www.blogger.com/profile/10773887469972534979noreply@blogger.comtag:blogger.com,1999:blog-6130126685334700207.post-4310113466833525102009-07-15T12:43:03.135-07:002009-07-15T12:43:03.135-07:00It's neat to me that in the fullness of time, ...It's neat to me that in the fullness of time, scientific truth was revealed almost simultaneously.

The natural world is wonderful. I have really been digging on the general theory of relativity this year. I can't do the math, but there is an excellent discussion in a book called On The Shoulders Of Giants by Hawking. The gigabytes of brain covered there awe me.dr killnoreply@blogger.com
