Initally, I was intimidated by this assignment. I don’t read science journals on a daily basis – actually I don’t really read them ever – and I was weary about where to begin. However, I …
If you read/follow any weblogs, you’ll find that reader comments can be one of the more interesting aspects of a given post. Comments can add a level of participation and ‘conversation’ that extends beyond the …
Can you imaging being in the middle of this?

The header image for this website is a simple mod of the default image that comes with the theme. While I appreciate the elegance of its simplicity, I’d like to find something that better reflects …
From Linked and knotted beams of light
third, we show that approximate knots of light may be generated using tightly focused circularly polarized laser beams. We predict theoretical extensions and potential applications, in fields ranging from …
The Large Hadron Collider (LHC) is now online and we’re still here, for now… here’s a little to tide you over until then:
First beam in the LHC – accelerating science
‘Greatest Physics Experiment Of All Time’: …
The fluorescing characteristic of a Xanthene-based Zinc (II) complex chemosensor has been the recent study at Kyoto University (Ojida, Akio; Takashima, Ippei; Kohira, Takahiro; Hamachi, Itaru. J. Am. Chem. Soc., 2008, 10.1021, p12095-12101) A chemosensor …
Like the molecule for week 1, I chose this just because I think it’s pretty cool. Published in the Journal of the American Chemical Society (Sessler, J.L.; Kim, S.K.; Gross, D.E.; Lee, C.; Kim, J.S.; …
We built on our discussion of symmetry and introduction to character tables by ‘generating’ the character table for the C2v point group using the set of coordinate vectors (and the idea of ‘orthogonality’), and defined …
The NTP (National Toxicology Program) has released its report on Bisphenol A. Of the four conclusions presented, one reflects some concern, one minimal concern, and the other two negligible concern. Note that the possible levels …
I’m obviously thinking too much!
taxing mental effort appears to cause people to eat significantly more food, even though it doesn’t burn many more calories than sitting around and relaxing

The focus this week has been on molecular symmetry, symmetry elements and operations, point groups and point group assignment, with a brief intro to character tables.
A few take home points:
a molecule is considered to have …
