it's 9 am so i'm in front of the computer ready to talk about #physics#biophysics@physics with anyone who wants to talk about physics.
i'll start a video chat if anyone responds here to this post. check out my intro physics google doc in my profile and think of some interesting physics questions.
This looks like a step forward in the science of earthquake forecasting.
A team from Sandia National Laboratories have studied the release of noble gases caused by induced underground explosions. Their detection could be one day use to monitor earthquakes or explosions.
@arstechnica 👆 Sidebar: I need somebody knowledgable to go into the question about the feasibility of a #hydrogen infrastructure. H looks promising, but besides the fact that it's another fuel lock-in - in contrast to (improving) batteries which will take electricity from any (improving) sources - H is a highly combustible invisible gas which burns with an invisible flame & transports under high pressure, spelling a logistical nightmare to my layman's eyes...

I'm friendly and follow back, feel free to connect if you'd like. :)
What does the Soyuz spacecraft and neutrinos have in common? They both figure prominently in a great hard #SF novel I just finished reading .... Quantum Space by @dpscifi . Now I have some #physics homework to do (plus check out the next book in the series Quantum Void)! #books
As requested by Reid Alderson, ChemEx is now in #NMROnline!
We would like to thank D. Flemming Hansen (@dflemminghansen) for providing the data, and Guillaume Bouvignies for his support with the ChemEx integration.
Short story time:
When I was doing my PhD, we had in the lab an old Argon laser (which we used to pump a Ti:Sapphire, for those familiar with lasers). If you have never seen one, Argon lasers are massive, can output a ton of power, and eat a crazy amount of current, so much that the laser had its own dedicated industrial pentaphase plug.
I don't remember how many Amperes of current flew in those cables. What I remember is that, when you turned on the switch in the morning, the change in current (from zero to whatever the steady state value was) was enough to make the cable shake.
This happens because the electromagnetic field inside and around the cable stores momentum, and so it kicked the cable when building up.
I am not sure that laser still exists, and I have never been able to find a video of a cable shaking when the current is switched on, but it would be great to have such a video when teaching electrodynamics (and in particular how momentum and angular momentum can be stored in an electromagnetic field). #ITeachPhysics#Physics#Electrodynamics#Laser
If a theoretician write "we use experimentally feasible parameters", what they mean is that they are using numbers that are just two or three orders of magnitude away from what is considered reasonable by experimentalists. #Physics
Fusa Miyake discovered that cosmic events that cause brief 14C spikes in the atmosphere are recorded in tree rings and was able to correlate this to precise historical years (now known as Miyake events)
This allows radio dating of historical events to single year precision.😮 #physics#history
General #phd thoughts: significant developments in the viability of my distributed systems agenda in the past month now have me seriously considering applying this fall. (This is one of the short list of things I would go back into #CS to do).
Specifically, I'm probably >80% confident I can self-fund on this.
I also may be strong enough in quantum error-correction at this point to consider applying to some #physics programs, but I've got more work to do there.
This is the best hour-long rant a #physics PhD ever delivered about #stringtheory and #SciComm while simultaneously playing Binding of Isaac in order to help stay focused on her talk
