I'm pretty sure there's no way to cast a vote. The naming rights go to the discoverers, and IUPAC can approve or disapprove of the name and symbol. What has to happen is first the discoverers have to be persuaded to choose the symbol J (you can find their e-mails by doing a simple internet search) and the IUPAC naming committee (link to their page here:

As you may have heard, all the elements in the 7th period have now been officially recognized by IUPAC and will receive names and symbols. There is an exciting opportunity here, as credit for element 113 goes to a Japanese team and may very well be named Japonium. Currently, the letter J is completely absent from the periodic table. I think that element 113 should receive the symbol J for a numbe...

Sat Dec 19, 2015 7:44 PM in Flat Earth Society--For Real?
Hi All, I recently happened upon some videos asserting that Earth is not round, but is in fact flat. I assumed they were satire, probably with Creationists as their target. I followed the videos to their source at The Flat Earth Society. I looked around the website, and if it is satire, they are working very well to hide that fact. I can find nothing on their website that indicates that they ar...

4 Good introduction to moment of inertia
Almost everyone is familiar with inertia and that objects resist changes to motion, but I think the idea of 'moment of inertia' eludes many. This is unfortunate, because many important objects in our life spin, and you can't understand spinning motion without understanding the moment of inertia. The full story of what a moment of inertia is and how to assign one to an object is worth exploring for those who wish to go deeper. It would also be worthwhile to find some objects of differing mass to roll that result in a tie. In any case, I encourage any one who lacks insight into the nature of spinning motion to start with this article.

5 For those who wondered
This is a delightful little article that explains words that are tossed around a lot in science class, but unfortunately are not very well understood by many people. This article is great starting point for anyone who is confused about the difference between law, theory, and hypothesis.

5 At last, one for the biochemists
At first I thought this SciPack was going to be largely redundant with other SciPacks that discuss cell growth and functions, and at one level it is, because there is nothing fundamental in it that isn't addressed somewhere else. That said, this SciPack goes into much more chemical detail as to the "how's" of energy generation and consumption, giving specific details as to the chemicals and mechanisms involved, as well as the energy balance sheet (what you put into the system and what you get out). This SciPack is the place where biology meets chemistry, so if you are ever interested in knowing the mechanisms of cellular function (instead of just glossing over it and saying "that's just how it is"), this is the SciPack that will take you there. Alternatively, as a chemist, it's your chance to see chemistry played out on its most exciting stage: life.
