The electron is a sphere

Nature is publishing a new measurement of the electron, to a precision of 0.000000000000000000000000001 centimeters.

Thank you Digital Academy Students

Just a quick note to thank all of the Digital Academy students who went on the field trip today. You are all such a fantastic group. It’s a pleasure to know all of you.

Website Structural Changes

The Chemistry Book has finally moved to some of the latest technology available on the Internet: social networking streams, activity streams, and improved forums.

What software packages are behind the changes?

The software behind the new features is BuddyPress, a plugin available for WordPress. Complementary plugins include Welcome Pack and Tweetstream. Other plugins are being tested.

What are the benefits?

BuddyPress provides the new forums, groups, and activity streams. Tweetstream allows you (you don’t have to!) sync your tweets with your activity stream here. The Welcome Pack allows me to modify the backend and clean up some of the messages, eg. signup email.

The BuddyPress theme includes a sidebar widget, linking to other sections of the website. Yes! The Learning Guides, Labs, Lecture Notes, etc are now available with a clear link on the right side.

Why do I have to register again?

Yes. It is true. To get these new features you will need to register with the WordPress (WP) portion of this site. Even though WP was installed a year ago, no students were required to register. The WP registration is different from The Chem Book wiki and requires a separate database.  During the upgrade, only one student’s information was removed (Sorry Anthony).

Why can’t I upload an avatar?

Avatar upload fails. This is an issue with the current BuddyPress version. Developers expect to have a new release in a few weeks and hopefully this will be fixed. Until then, go to www.gravatar and upload an image. Use the same email address you use on this site – and this site will pickup your gravatar.

Ununbium: Element 112 finally has a home

NIST periodic tableThe International Union of Pure and Applied Chemistry (IUPAC), confirmed the discovery of 112 by the team led by Sigurd Hofmann at the Helmholtz Center. The team originally announced six elements, in which the other five have already been accepted by IUPAC. The team announced the discovery in 1996 but it has taken the past 13 years to confirm the discovery because the element only last for a fleeting moment. IUPAC is now requesting names for the superheavy element.

Element 112 is one of 22 man-made elements. The element is a fusion of the nuclei of lead and zinc created in a particle accelerator. The element has an atomic mass of 277, containing 112 electrons and 165 neutrons.
