This Vanity Fair piece gets most of it right: keeping up keeps you young. True for many scientists I know as well.
And for the record, Radio City Music Hall is a wonder.

NY Governor David Paterson is at BNL today, in part to announce this:
Gov. David A. Paterson is expected at Brookhaven National Laboratory today to tout approval of a LIPA project to add 50 megawatts of solar power to the local power grid - among the largest in the country.I've got my seat -- and my laptop, so I'll post anything else I hear (besides the Billy Joel muzak being played as we wait). I suppose we still call that live-blogging, but just saying that sounds so old fashioned. Maybe I should twitter it?
Long Island Power Authority trustees yesterday approved the selection of four solar power firms to erect photovoltaic stations at locations across the region. In addition to Brookhaven Lab, they will be placed on rooftops and parking lots of the Plainview- Old Bethpage Central School District, at landfills in Oyster Bay and Islip, and atop a real estate business.
LIPA hasn't released the cost of the project. Acting LIPA chairman Howard Steinberg said residents should expect the power to cost from two to three times that of conventional fossil-fuel plants.
Paul DeCotis, Paterson's energy chief, said LIPA can expect funds from the recently approved federal stimulus package to help defray part of the "green premium," as well as money from state renewable programs. He said the solar power project will be the first major leg of Paterson's push for 45 percent of the state's electricity to come from efficiency and renewables by 2015.
But now that I poke around a bit, I'm a little confused: the Times reported on this issue on Feb 13 and mentioned that LIPA is raising electricity rates by 3.2%. RHIC research is quite dependent on power costs, so will this be a net gain for the lab, after all, despite being a major source of renewable energy for the region? Or will this eventually make the lab's power cheaper, as it would be if you installed it on your own home? Stay tuned.
Update: pushing 2:10 and no Paterson -- someone next to me commented about 200 wasted man-hours.
Forgets Byron Foley -- "you know how they say 'you always forget the one you love'" and apologizes. He's hilarious.
2:19pm DOE has awarded $913M in capital money for the new light source (NSLS II). Wow.
"If I know any more than that I will actually come help with the research."
1000 jobs in construction -- mostly from people who live in Long Island.
BNL has estimates 63M hours of labor needed for NSLS II.
Big announcement: 50MW of hydro power for BNL from LIPA. Lower cost for operations of lab activities, just for NSLS II or for RHIC?
Triple threat: DOE funding, BNL expertise, NY will supply the power. Colleges and universities will be great beneficiaries.
"But there's more"
Feb 11, 2008 was charged for developing recommendation for renewable power. proposal for 50MW of photovoltaic power. Got back opportunties for 400MW, and looking for a venue.
Today: announcing private investor will lease property at BNL, central station solar power plant here at lab!
BNL, along with LIPA and NYSERDA will collaborate to put this in place. Part of getting 45% of energy from renewable sources by 2015 -- BNL solar plant will be a major contribution. "45 by 15" will yield 50000 jobs in NYS.
All of these can also heat hydrogen ("not nitrogen -- I get letters about this stuff") to help store power.
Called BNL a major leader in scientific research and fuel cell research. Benefit to NYS and Long Island, and will transform the US power to produce energy and clean up the atmosphere.
Paterson is done!

At the annual meeting of the American Association for the Advancement of Science last week in Chicago, the sessions covered a wide range of scientific fields, from climate change to the intersections of mathematics with origami. Of course for me, the highlight was the symposium that I organized with Bill Zajc, professor at Columbia University and former spokesperson for the PHENIX experiment at RHIC.
Titled “Quest for the Perfect Liquid: Connections Between Heavy Ions, String Theory, and Cold Atoms,” the session covered the emerging relevance of the physics done at RHIC to other subfields of physics, ones that were never thought to be related.
It included speakers both from within the RHIC community, as well as from fields who turn out to have a closer connection to RHIC physics than had been realized. It turns out that physicists from three separate fields are all intensely interested in the physics of strongly-coupled liquids, which flow so easily that they are called “perfect” liquids.
PHENIX spokesperson Barbara Jacak of Story Brook University presented the major results from RHIC, which has been providing collisions since 2000. She paid particular attention to the main features of the medium formed in heavy ion collisions at RHIC: that it flows like a near-perfect liquid, a property intimately connected to its ability to stop the motion of fast-moving quarks (both light and heavy). Using these data, RHIC scientists are able to determine a particular ratio -- that of viscosity to entropy density -- to be quite small.
John Thomas, an atomic physicist from Duke University, presented his experimental results on ultracold atomic gases. In these experiments, clouds of atoms are released from optical traps, and their expansion is visualized by laser flash-imaging techniques. An external magnetic field affects the coupling of the atoms and can be tuned to put the system in a strongly-coupled “universal” regime. Here, the system acts in a way similar to RHIC collisions, expanding asymmetrically according to the laws of fluid flow. The viscosity to entropy density ratio has also been measured here and is as low (or maybe lower!) than that found at RHIC.
Rounding out the presenters was (notable blogger) Clifford Johnson of the University of Southern California. He described how the mathematical techniques of string theory are elucidating the properties of these strongly interacting near-perfect liquids, based on the ideas of string theory. These techniques are used to draw a connection between a strongly-coupled quark-gluon liquid in our world of three spatial dimensions and a gravity theory living in four spatial dimensions with a black hole sitting deep in the fifth dimension! While this scenario sounds strange, it provides one of the few concrete predictions arising from string theory calculations -- that the ratio of viscosity to entropy density has a lower limit, a value which seems to be observed by both RHIC and the ultracold atomic physics experiments.
The serendipitous convergence of these three separate fields has been very exciting -- and useful -- for everyone involved, giving all of us the strong sense that we are only starting to grasp its implications. And it is quite striking that the tools of string theory have provided a sharp, testable prediction for the first time -- one that seems to be borne out by experiments from completely different fields.
Our symposium was attended by over 120 people, ranging from high-school students to scientists in a variety of physics subdisciplines, showing the wide interest this emerging field of science has attracted. It was subsequently covered by several physics blogs.
Symmetry magazine’s assistant editor Glenda Chui served as a discussant along with Bill, and they both addressed questions to the speakers following the talks.
Chui herself posted a blog (http://www.symmetrymagazine.org/breaking/2009/02/16/a-first-string-theory-predicts-an-experimental-result/) a few days later, which was picked up by digg.com. The interest in Chui’s blog was so great that it overloaded Symmetry's server, necessitating a major upgrade. The comments to the piece show that connecting experimental data to string theory is controversial, especially if this is used to argue for the “reality” of string theory. But such debate is fitting for the kind of forefront science we do here at Brookhaven with RHIC.

Our apartment is just a few blocks from Madison Square park and can even see the Met Life Tower from the window. I also happen to drive down 23rd St whenever I head to the Midtown Tunnel to get the Brookhaven (a rare event these days, now that I take the LIRR more often). I find the tower a magical structure, particularly when I try and imagine just how huge the clock face must be.
And, something I stumbled on a few months ago completely blew me away. This one is about the Met Life North Building, something not as noticable in the shadow of the gorgeous 770 foot tower. Turns out that it was the base for a planned 100 story skyscraper, but the crash of 1929, um, "descoped" the project a bit. Who knew? But now every time I drive by, I find myself wanting to see the real tower, and not just this beast.
So not exactly world-shattering, but certainly droplet-shattering. I was curious about people who had done this kind of thing -- and Google was kind, yielding up Robert Park's interesting web page. Image after image (and movies) of water droplets colliding: slow and fast, symmetric and asymmetric, head on and glancing. Interestingly, a colleague of mine looked at these yesterday and saw very low-energy nuclear physics (neutron necking, and the like). I looked at these and tried to imagine them relativistically.

- Thursday, reaffirmed my faith (shared by the family Obama) that Avec is one of my favorite restaurants in the country, but I can't figure out how to describe it
- Friday, grappling with the almost-unmanageable AAAS sprawl, learning a bit about scientists in Hollywood, and huge events by Sean B. Carroll, Al Gore, and the Ig Nobel folks
- Saturday, skipping the science of kissing for the arts of getting scientific insight to Congress (with the impressive Bill Foster), learning about the human propensity for blinkenlights at the BNL booth, the joys of neo-Origami, Chicago evening fireworks on the river, and the fun of science journalist parties (and congrats to the AAAS award winners!)
- Sunday, the wonders of Houlihan's breakfast, surviving our symposium (audience shown above!), missing the Higgs discussion at the FNAL/CERN symposium, and bumping into a few physioblogospheric luminaries (yes, that's two Sean Carrolls in three days...)
