12:17 AM | Cs 137 Spectrum at Last? Lab Book 2014_07_19
Summary:  I'm still checking and re-checking the NaI detector.  I've yet to get a reliable spectrum out of it, but last night's run at least has distinguishable peaks.  The company that made our detector 50 years ago believes that we probably do have an RCA 45xx series photomultiplier tube which would mean that the 2400 V bias I have to drive the tube at to get  a signal is actually OK.  The 45xx series has a maximum bias voltage of 2500 V. If you're new to the […]

5:04 PM | Mapping Mars at night
Sometimes to get the best map of Mars, you need to take your photos at night. Admittedly, those photos are infrared, and the map isn’t your typical planetary atlas. Instead, researchers assembled more than 20,000 photos taken from orbit during the Martian night to find out how different parts of the planet surface retain heat […]

12:48 PM | How quantum mechanics explains global warming
posted by @ulaulaman about #globalwarming http://t.co/VDlaEt2s5m The physician Mark Schleupner, a Ronaoke native, writes about global warming: So, according to NASA scientists, if all the ice in 14 million sq km Antarctica melts, sea levels will rise more than 200 feet. Greenland alone has another huge chunk of the Earth’s water tied up in ice; some scientists say that its ice sheet has passed a tipping point and will be gone in the next centuries, raising ocean levels by 24 feet. These […]

12:46 PM | The Silent Centennial of Space Exploration
Noisy revolutions often emerge from quiet beginnings. So it was with the revolution of the Space Age. Forty five years ago today, a Saturn V rocket roared off from Cape Kennedy and carried the first humans to the moon; Buzz Aldrin and many others are marking the anniversary with live and virtual reminiscences (NASA has […]The post The Silent Centennial of Space Exploration appeared first on Out There.

10:39 AM | The meaning of exponential | Jon Butterworth | Life & Physics
Why populations explode, and why traces of radioactive elements can hang around for a very long timeExponential increases, and decreases, pop up quite often in various contexts. The word is generally used as an impressive adjective to imply something happening really fast and getting faster. This isnt always sensible. In fact exponential decreases start fast and get slower, hence the problem with radioactive waste hanging around for ages. Continue reading...

I didn’t want to post about this until I knew it would happen.  I’ve had bad luck with my training in the past: I’ve attempted twice to train for a half-marathon, both times being unsuccessful for health reasons.  (One was directly related, but the other was not.) Today, however, I have managed to cross that […]

8:39 PM | My LonCon Schedule
Since lots of other people are posting their Worldcon progrm(me) schedules, I might as well share mine, too. Frankly, I find it a little baffling: Kaffeeklatsch Thursday 18:00 – 19:00, London Suite 5 (ExCeL) Kay Kenyon, Chad Orzel Banksian Saturday 11:00 – 12:00, Capital Suite 9 (ExCeL) ‘Banksian’ has become a commonplace descriptor in SF…

7:27 PM | A billion-year monument
More than four and a half thousand years ago, a square was marked in the desert a few kilometers west of the river Nile.  It was a blueprint, writ large, for the construction of what would become mankind’s most enduring achievement.  For the next twenty years, large stone blocks would be hauled into place, one every five minutes, day or night.  Six million tons of stone later, the greatest of the pyramids was complete.  (Image […]

7:00 PM | Latest News from the Universe: LambdaWDM, CMB,Warm Dark Matter, Dark Energy, Neutrinos and Sterile Neutrinos
The new concordance model in agreement with observations: ΛWDM (Lambda-dark energy- Warm Dark Matter). Recently, Warm (keV scale) Dark Matter emerged impressively over CDM (Cold Dark Matter) as the leading Dark Matter candidate. Astronomical evidence that Cold Dark Matter (LambdaCDM) and its proposed tailored baryonic cures do not work at galactic and small scales is staggering. […]

4:00 PM | IAU 311: Galaxy Masses as Constraints of Formation Models
In the era of precision cosmology, we think we can accurately predict the distribution of dark matter in the Universe. However the impact of baryonic physics is still largely unknown and our understanding of galaxy formation must rely on observations. A key advance in recent years has been the ability to enrich studies of the […]
