Neutrinos to Give High-Frequency Traders the Millisecond Edge
Bruce Dorminey writes about the real edge the big boys have...
30 millisec trading advantage on the NY/Tokyo spread is nothing to sneeze about, just get some pulsed collimated neutrino burst generators, swap your low bit unbreakable one time pads and go wild on the arbitrage as you trade your Ningi for Cold Pressed Latinum Bars!
but we knew this...
"...The most interesting applications of this would of course be for signaling; however there private enterprise is way ahead of us, and clearly some very clever hedge fund…

catdynamics | April 17, 2012The European Space Agency has made its selection for the next Large Mission to be flown by ESA, with a launch window in about 2022
and the winner is... JUICE
Jupiter moons orbiter.
Formerly known as Laplace.
The losers were ATHENA - a descoped version of IXO, the third version of the next generation x-ray observatory, and, NGO, aka eLISA - the descoped version of the much beloved LISA, the long proposed space based gravitational wave observatory.
Some residual funding for x-ray optics, and laser systems will be provided to provide technological readiness for future mission opportunities…
catdynamics | April 4, 2012we just switched to a "no can" policy
in practise, what this means is that rubbish bins in our offices are no longer emptied (though they are still there, and I helpfully pointed out that most of the bins had not been emptied that one last time when we switched this month - they were emptied this morning...)
instead we have 8 (I counted) sorting bins in the hallways, most of which are for recycling, of course
this is a good thing, and the goal is to get to zero waste (not possible, too much stuff is wrapped in that unrecyclable soft plastic that ends up in landfills)
so now I pile garbage on…
catdynamics | April 2, 2012Every other year NASA conducts a Senior Review of its astrophysics missions that have completed their nominal mission and are requesting an extension of their mission.
The 2012 review panel just reported.
The panel had an interesting task - to rank in priority the operating missions:
Chandra
Fermi
Hubble
Kepler
Planck
Suzaku
Swift
Warm Spitzer
XMM-Newton
Kepler and Fermi are being reviewed for the first time, as is Hubble , as effectively it goes into a "new mission ops" mode after refurbishments.
Hubble and Chandra are large missions with large operations costs; Kepler, Fermi and Spitzer…
catdynamics | April 2, 2012snippets to ponder:
"Gods as Topological Invariants" - D. Schoch
"We show that the number of gods in a universe must equal the Euler characteristics of its underlying manifold. By incorporating the classical cosmological argument for creation, this result builds a bridge between theology and physics and makes theism a testable hypothesis. Theological implications are profound since the theorem gives us new insights in the topological structure of heavens and hells. Recent astronomical observations can not reject theism, but data are slightly in favor of atheism."
Close a hole. Kill a god!

catdynamics | March 27, 2012Many of the Hubble Space Telescope images have never been looked at.
You can now browse the archives and win valuable prizes for finding cool new pics.
This is a cool, fun thing, and it is easy enough for a theorist to do.
Hubble Hidden Treasures - How To
With an iThing and the Dynamic Kids, we had pulled up several dozen sets of images of selected patches of the sky and browsed them, and found seriously cool pics within about 20 minutes.

catdynamics | March 26, 2012This here blog has not ceased to be,
appearances to the contrary not withstanding.
It is not elevating the asteraceae,
it is just resting.
Seriously.
The lack of activity this month is deplorable, and all my fault, as real life has made a forceful appearance.
Normally this sort of tapering off in activity is a blog death sentence, but I have not been short of material, just time.
Life has also been complicated by impending changes in layout, and the fact that I backed myself into a situation where I have assumed or been given Real Life Obligations that sharply limit my ability to…

catdynamics | February 28, 2012Hey peeps
Anyone care to comment on what is going on with their prospies?
Either outoging μgrads or incoming?
I'm worried the statistics on prospies are wonky this year.
Are people holding back on apps?
Using waiting lists more?
Students continuing to apply to more schools than before?
I'm also not seeing the sort of chatter in the forums and cafes that I've seen in previous years.

catdynamics | February 15, 2012The standard solar model predicts a young Sun which was too faint to sustain liquid water on the Earth, unless there was an extreme greenhouse effect at the time, which seems to contradict the geochemical record. It seems to be almost impossible to get liquid water on Mars under the standard solar model with any plausible early Mars atmosphere.
Here is an interesting article on an old problem...

catdynamics | February 9, 2012There are several signs o'doom for NASA bubbling up out there
GALEX is going into standby mode in preparation for shut down.
It is working fine, but past its design lifetime, as so many NASA satellites do nowadays, and there is no more money for mission operation and data analysis.
There is a rumour that Caltech hustled for some private money to extend MODA, but they may not be able to do it anyway, because of liability and ownership issues.
So it goes.
At the same time there is SenseOfImpendingDoom at NASA - lot of 2011-12 programs appear effectively suspended pending the 2012-13 budget, to…
