— Thanks Tea Party. What is it again that you guys contribute to society?
There are 5.7 million scientists and engineers in the United States. They make up the largest percentage of the workforce in Los Angeles, Denver, and Boston, all of which are great places to find a science job.
Today I don’t have to give attribution for this graphic or study, because the National Science Foundation website is shut down.
Since water is diamagnetic, i.e. is very (very) weakly repulsed in a magnetic field, you can use a big magnet to levitate anything containing water like cherry tomatoes, frogs, and grasshoppers. Don’t recall the details, but when this research came out I read the paper and I think the magnet was the size of a room with all the cooling, etc, and the hole was just big enough for the smallest kind of tomato and a tiny species of frog. There might be a lawyerly clause in Magneto’s contract that excludes paramagnetism and diamagnetism. PS It said it didn’t hurt the frog that I remember.
“The news is bad.” That’s how Photon Sciences Accelerator Operations Group Leader Emil Zitvogel started an email to key individuals, alerting them to a vacuum leak that occurred in the NSLS X-Ray Ring on Saturday, June 15.
I was complaining about this a while back because I was supposed to have time at the National Synchrotron Light Source starting that weekend. It was finally fixed on July 8. They were nice enough to write an article about the dudes who actually fixed it.
In the coming weeks Clear Science is going to talk about how carbon from CO2 gets stitched together into chains of carbon. That’s called “carbon fixation” and it’s how the carbon you’re made of initially gets put together that way.
It’s important for global warming, because when you burn fossil fuels like we are you’re making CO2 way faster than plants/bacteria can stitch it back together.
Whoever made that cool transparent png of a tree, thanks man.
Proving He’s No Fun Since 1974: The Osmium Story
I think my new hobby is going to be very precisely correcting Neil Tyson every time he says something that sounds nice but actually dumbs down the science so much that it’s wrong. Communicate UP to people not DOWN.

Occasionally I do this when I need battery materials: Crack open a D cell battery and pull out the anode.
The anode is a gooey cylinder at the center of the battery. In the second picture I’ve peeled off one layer of cellophane and one layer of paper from the anode. Inside it’s just a shiny jelly of zinc particles. Zinc is a high energy material, so by dissolving it you can get power. That’s how a battery works, basically.
There’s a cathode too, which is made of manganese oxide. It’s a black powder caked around the inside of the cell. You can also see the nail or pin sticking up at the center. This is the electrical contact to the zinc jelly.
Karl Kordesch, the chemist who invented the alkaline battery, died in 2011.
Billy Squire - My Kinda Lover
You got my motor racin’
I find my thoughts embracin’ your every move
I wanna set you reelin’
I wanna make you feel the way that I do
I been thinkin’ ‘bout you for so long
I don’t wanna lose ya—you’re my kinda lover”
Last night I was listening to Radiolab and I swear they were incorrectly using the scientific terms stochastic and chaotic. I was drunk so maybe I misunderstood. Anyway I started writing a post explaining it. But really who wants that. If someone who’s not a computer scientist ever says the word stochastic you know with 95% certainty they’re full of shit, what better definition do you need?
Check me out. Username: chels who works at Brookhaven National Lab wrote a nice story about my battery work there with my friends Can (who is Turkish) and username: steingart (not pictured). Science: it is a Tumblr Party Come To Life, man.
