    Unc, look at this and tell me what you think. [url]http://hypography.com/forums/strange-claims-forum/22596-photon-creation.html#post292772[/url]

    Look at the parity experiments? The mathematics of geometric parity divergence applied to chemistry was published. The cheminformatics community has been powerless to systematically label the central five stereocenters in [6.6]chiralane, [url]http://www.mazepath.com/uncleal/schwartz.png[/url] [url]http://www.mazepath.com/uncleal/schwart3.png[/url] [url]http://www.mazepath.com/uncleal/chiralane.pdf[/url] [url]http://www.mazepath.com/uncleal/parity.pdf[/url] The parity physics experiment were also published, Physics ignored it, but now there are four classes of experiment, 1) parity Eotvos, 2)parity calorimetry, 3) parity gyroballs, and 4) party molecular rotation spectra, [url]http://www.mazepath.com/uncleal/twistene.png[/url] I'll write it up and take a crack at Phys. Rev. D end of February or so.

    Copper and silver form a wide range of alloys. Stripping copper from the contact interface could be difficult. In principle you could selectively dissolve the copper as anode with a suitably low voltage. Chemical etching might work, [url=http://pubs.acs.org/doi/abs/10.1021/cm950464%2B]Microcontact Printing of Alkanethiols on Copper and Its Application in Microfabrication - Chemistry of Materials (ACS Publications)[/url] "Since aqueous FeCl3/HCl solutions only dissolve bare copper" Try it on a small spot before committing.

    Hello Sir, Iam not from a science background but i desperately need to know how to separate copper from silver without any change in the silver.The silver is in a closed 3-D shape with a hole at the bottom and no change can be made on it.The copper is the inner wall of it.Please advise.I have an electro plating plant at my disposal. THANK YOU

    Six fullerenes are perfectly chiral: Point group T: C44, C52, C92, C100 Point group I: C140, C260 [url=http://www.mazepath.com/uncleal/chiralan.htm]Parity Divergent Molecules[/url] middle If you want a listing by carbon number and point group symmetry of all allowed fullerenes through C260+, it's a 4 MB ZIP archive. However... their structures are only crudely minimized. You'd have to run each coordinate set of interest through BABELwin into *.hin format and then MM+ mininmize in HyperChem-Lite after auto-assigning atom types.

    Uncle Al, at last we meet (in a manner of speaking). It is an honor. I thoroughly enjoy your posts, as well as your rapier wit. I suspect you know a great deal about one of my interests: fullerene chemistry. I must say however that my interests are tempered by the sobering fact that as a NASA "rocket scientist", I am (by definition) not an expert in anything. :( Take care. :wave2:

    i agree definitely Datura. maybe Datura discolor ? [url=http://en.wikipedia.org/wiki/Datura_discolor]Datura discolor - Wikipedia, the free encyclopedia[/url]

    on the Datura id Al, i don't think D. metel because of the very thorny fruit Destrb has photographed. according to wicked pediac :evil: D. metel has lumpy fruit with few thorns. [url=http://en.wikipedia.org/wiki/Datura_metel]Datura metel - Wikipedia, the free encyclopedia[/url] i see at the same link that D. metel has oval leaves, and again Distrbt's photo not oval but lobed.:clue: :sherlock: over... as to shoes falling identically, not in a wind they don't. :fan: :ideamaybenot:

    i got the contest page read last night, very cool idea, and your entry intro and the comments you have accrued. i have to go back to your full pdf but i'm presuming it is the experiment as you have described it here before. anyway, so-far-so-good and i voted my concience with a big phat 10. :D maybe now, someone [U]will[/U] look. :sherlock:

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

When we launched in May 2000, we wanted to create a site to share science-related content of all kinds on the web. As time passed, our site turned into a pure science forum with lots of cool people.

So we kept the name Hypography and the cool science forum community - and aim to be a friendly place for discussion of science topics of all kinds.
