Cosmic Collisions: Galaxies, an astronomy special, one of three,
is airing tonight (wednesday 18th January) at 10 pm eastern/pacific, 9 pm central
oh it is on the discovery channel.
PS: here is the full schedule for Cosmic Collisions

I hear two more "Cosmic…
I missed the session on tuesday of "Short Talks: Structure of GCs and Their Dynamics",
fortunately the audio and video feed is here for posterity
Fujii, Varri and Waters present.
how big is a globular cluster?
There are many ways to measure the size of a globular cluster, both observationally and theoretically.
This causes some confusion, especially when theorists try to talk to observers, or vica versa.
rc - the core radius
there are at least three definitions of this:

wherein you can learn about the "No Teleportation Theorem" and why there is no classical Scattering Theorem
or some such nonsense...

Argh.
one of the nice, but occasionally disturbing things about the Kavli Institute of Theoretical Physics is that they podcast…

Situation in Iceland is getting worse every day.
PM is out; fish exports are down sharply because of lack of buyers - partly lack of credit by European importers, partly economic collapse in eastern and southern Europe - this could crush any prospect for short term recovery.
Larger protests…
it is still raining?!
so we have an east coaster telling us about actual data
on x-ray binaries
in clusters, globular clusters
in other galaxies...
there is an open-to-the-program-members blog over on the cluster09 wikispace.
It has some good summary of yesterdays in depth discussion on runaway…
it is raining, might as well liveblog the morning session...
runaway mergers of colliding stars - the quick and dirty intro...
stars are, in fact extended bodies.
This is mostly irrelevant to astronomers, since typical stellar separations are very large.
But, in dense stellar clusters, the…

Multiple stellar populations in globular clusters (overview).
like this in NGC2808 (paper)
or even good old M4, and and NGC1851, and of course Omega Cen.
the original view of globular clusters is that they are the quintessential coeval sets of stellar populations - that all the stars in any…
it is cloudy and cold...

Change is good, right?
Nice of Sean to take the blame, just in case someone is feeling curmudgeonly about it.
Not that they should, since the option of continuing the old way by default is still there...
That is change we can live with.
getting organized
- unlike the totally laid back string theorists, the astrophysics program has daily morning meetings to discuss progress
except today
today we get to meet after lunch, everybody was kinda busy this morning for some reason...
then we get informal short talk presentations once a…
New calculations suggest the question of whether the universe is holographic or not is testable, and recent data is consistent with the model, and consistent with the universe actually being holographic.

ok, let's try the hispanic broadcast since HBO seems to think they own the other version

The proposed economic stimulus package includes some funding for science.
Chunk for NSF, lot of facility funding.
NASA gets climate science.
DoE gets some toys.
Appropriations Stimulus 0115 (pdf)
The total package is somewhere in the $800+ billion range, as proposed.
With about 1/3 proposed as tax…
D
we set D equal to the measured value from A.N. Experimenter et al (2009)
we set D = 8π3/2/3 (Stokes 1854)
we set D = 8π3/2(1 + ε)/3, where ε = 4.2*10-7 is the Me-Stokes parameter (Me 1973), correcting for second order effects.
do you mean a total derivative or a partial derivative?
well, the "…
I am currently at the Kavli Institute for Theoretical Physics, hanging out at the "Formation and Evolution of Globular Clusters" workshop.
Apparently I am, for now, also the official "program blogger" program rapporteur...

Hubble supplemental decisions are done, e-mails are coming out this morning.
Score!
bloomin' heck.
Now what do we do...?
So, how did y'all do?
Hold on.
Phase II is due when?

my new office is probably the best office in academia
When I was in my final year as a graduate student, I had what I thought then was the best office in academia.
It had been Prof. Kip Thorne's office - on the ground floor on the north side, with french doors onto a balcony overlooking the Rose…
