Still Life: Five Glass Surfaces on a Tabletop, by mathematician Richard Palais and graphic artist Luc Benard. This image was awarded first place in the illustration category of the Science and Engineering Visualization Challenge 2006 and was on the cover of the 22 September 2006 issue of Science.

The five mathematical surfaces depicted are (starting from lower-left and moving clockwise): the Klein bottle, the symmetric 4-noid, the breather surface, Boy’s surface and the Sievert-Enneper surface.

“The reason I use math objects in my work is purely aesthetic, I find them so beautiful and strangely, they often are so organic,” said Benard. Read more.

I had just moved to New York, right on St Marks Place, and it was my dream to maybe see him play there some day. Sure enough, one night, it was harder than usual to get in, and there he was, doing his magic. Grace will forever be one of my favorites, and so will he. - Gerrit Sievert

This is a chart of the ionizing radiation dose a person can absorb from various sources. The unit for absorbed dose is “sievert” (Sv), and measures the effect a dose of radiation will have on the cells of the body. One sievert (all at once) will make you sick, and too many more will kill you, but we safely absorb small amounts of natural radiation daily.

Note: The same number of sieverts absorbed in a shorter time will generally cause more damage, but your cumulative long term dose plays a big role in things like cancer risk.

The poor conservatives - the world must seem a bit scary?

Is your political ideology in your head?

Conservatives and liberals know there is a chasm between their policy and social ideals. But a new study shows that their differences may be psychologically fundamental.

The research, led by the University of Nebraska-Lincoln’s Mark Mills, revealed that negativity bias – where greater weight in our cognitive processes is given to negative information over positive or neutral information – is stronger in political conservatives and that the negativity bias transfers to how well they remember stimuli.

In other words, conservatives in the study were more likely to remember things that evoked negative emotions – images of war, snakes, dead animals – than their more liberal counterparts.

2nd-4th photos- July 1937 -To mark the opening of the Beverly Hills Tennis Club, owners Fred Perry and Ellsworth Vines, former Wimbledon champions, teamed up with Charlie Chaplin and Groucho Marx,  Charlie Chaplin & Fred Perry vs Groucho Marx & Elsworth Vines. A battle of Britain against the U.S.

This was also their last - before parting Charlie said to Groucho “Stay warm”.  They died within months of each other in 1977. I love the look of on Danny Kaye’s face as he looks at Charlie.
