1:15 PM | Benefits of an Academic Day Job
I’ve been quieter than usual here, partly because I’ve been crushingly busy, but primarily because most of the things I want to talk about, I can’t. Not yet, anyway. But I’m still alive, and this murderous term will be over soon, at which point blogging will pick up a bit. I will throw in a…

12:00 PM | The Shadow Knows...
Image SourceThe Shadow knows (or, at least "they" do)."They" know without any critical thinking skills, reason, logic or investigative training. "They" know without any expertise that climate change is a hoax (even write books of pseudoscience on it), get reelected with committee appointments in congress over environmental regulation. Clean air; clean water; survival of the species: no problem! I guess the Department of Defense can scrap that whole pesky, fact-based road map.The […]

3:16 AM | YBCO Four Point Measurements: Lab Book 2014_11_15
I was back in the lab this morning.  I’m working on getting the four point measurement to work on the YBCO sample.  In the grand scheme of things, this is low priority, but it’s important to know that we can successfully make these measurements here before we have a large bucket of liquid helium evaporating with a sample inside.  Here’s what the four point probe measurement looked like:There are still no conclusive results.  With any luck this is a […]

5:42 PM | Magnetars! Explosions Occuring On Neutron Stars Due To Magnetic And Seismic Violence
Magnetars are neutron stars that have EXTREME magnetic activity, as well as intense seismic rippling.  These two attributes cause explosions on the surface of them, which is quite awe inspiring. Below is a new (late oct.) artist rendition of a magnetar, straight out of NASA's Goddard Studio.Image credit: NASA's Goddard Space Flight Center/S.

12:00 PM | Spooky Physics and Wormholes...
Image of a simulated traversable wormhole that connects the square in front of the physical institutes of Tübingen University with the sand dunes near Boulogne sur Mer in the north of France. The image is calculated with 4D raytracing in a Morris–Thorne wormhole metric, but the gravitational effects on the wavelength of light have not been simulated. WikipediaWormholes — shortcuts that in theory can connect distant points in the universe — might be linked with the spooky […]

3:00 AM | A Second Law for Open Markov Processes
guest post by Blake Pollard What comes to mind when you hear the term ‘random process’? Do you think of Brownian motion? Do you think of particles hopping around? Do you think of a drunkard staggering home? Today I’m going to tell you about a version of the drunkard’s walk with a few modifications. Firstly, […]
