When looking at the details of an account I noticed that it was temporarily suspended:
The suspension ends in 1992, or 2092, or generally speaking in *92. None of the years make sense.
What does that message mean?
"The only reason he did not purge physics of quantum mechanics is that he was told by Kapitsa in no uncertain terms that he will not have an atomic bomb without quantum mechanics"
What would be a theoretical explanation of an "ideal" 14:1 mass ratio in this experiment, also demonstrated in this video?
The experiment ties one nut to one end of the string and 14 nuts to the other, then holds the string like this and lets go:
The end with the single nut ends up wrapped ro...
I am building a set of 3D figures for online display (as supplementary material for a physics paper), and I am having some issues getting the transparency features to work.
Specifically, I have a set of surfaces built using the <IndexedFaceSet> primitive, prefaced with a <Material> element insid...
Cool -- hopefully there's enough nuggets in there to help you put together the solution then. I think it's just primitive z-buffering issues. The simplest solution might be to split the figure into two objects, back and front, then render the back one, then the front one
Is the surface analytical? Can you just create two surfaces, one defined for Z <= 0 and then another for Z > 0? Or make 2 full surfaces and clip them so the union of the two is the full surface?
I'm not sure what software made the original figures, so I'm using Paraview terminology for things I suppose
So then I guess the real question is how essential is the transparency. If they can rotate the object around, they can get a feel for its spatial relationships
Hrm... I don't know enough about it to be helpful, unfortunately. There's other web-visualization things out there, like vtk.js which will power ParaviewWeb, but at the end they are all just rendered by WebGL. So I don't know if they handle things better or not
@ZeroTheHero Well, I find "lunch I don't have to prepare and where I can chat with my colleagues and play table football with them afterwards" much more enjoyable than "lunch I have to prepare and mostly eat on my own"...
@ACuriousMind I suppose it's a generational thing... I actually enjoy much more the "lunch I can prepare where I don't have to chat with my colleagues".
yes... I was going to say that maybe it's an academia thing.
In Canada the universities are not technically closed although there are no students. Most of the profs and instructors are also working from home and indeed it is highly recommended for all staff to stay home if they can...
Finally the administrators have managed to run the university the way they like: no students or profs.
if they could only find a way not to pay the staff (except Deans or above) that would be totally ideal.
@JohnRennie The problem is not that I don't know how to cook. I just like it more when I don't have to worry about it every day and when I can eat my meal with some other people
I am currently conducting trials to see how good lemon cake is at preventing CV infection, and I'm pleased to report 100% success so far. Naturally the trials will have to be repeated many times.
@JohnRennie I'm sure with enough time and funding you could have done it right; but obviously we have to do what we can before it's too late. Clearly, you're doing your part.
As it happens I have a very poor sense of smell. I remember doing an experiment with a terpene in organic chemistry labs and being blissfully unaware that I was suffocating everyone else in the lab.
I am trying to understand if there is a way to estimate 3D movement using the below variables along all three axis and relative to the orientation of the device:
Attitude
Acceleration
Gravity
Heading
Rotation Rate

@ACuriousMind if you see the video, then you can clearly see that the baby is uncomfortable in the given situation. Also the babies are much more fragile and I don't think that it was appropriate to do it on a 1 month old baby.
Not watching the video, sorry. Babies can be made uncomfortable by plenty of things (ask any young parent :P) but I don't necessarily think it's "cruel" to do that. Regardless, unfortunately, making babies uncomfortable for a short period of time is definitely very low on the scale of cruel things done in the name of science...
I'm using a Bluetooth socket to send information from my phone to an Arduino. The problem is that btSocket.getOutputStream().write(bytes); is sending information too fast and the Arduino can't catch up with the emptying up and overflows. The code running on my Arduino slows down the Arduino's abi...
Could someone help, are Hermitian operators distributive in the follow way: $\langle\psi|(\hat H_1|\phi_1\rangle+\hat H_2|\phi_2\rangle)=\langle\psi|\hat H_1|\phi_1\rangle+\\langle\phi|\hat H_2|\phi_2\rangle$?
ah mathjax doesn't work like I thought, I didn't want to make an entire question out of it since it's fairly simple
basically can i "ket" the addition of two operators acting on two wfs and distribute the "ket"ing between the two terms?
Wow! I just used voice dictation do do that^ here for the first time. Have you guys tried it here?
to* do
I think I'm going to use it more often
But, then again, given the asynchronous nature of chat; it would be a lot like talking to yourself :P
@EmilioPisanty wise decision pal
The US went from "don't worry, everything is fine, we don't need any particular measure" to being the third country in the world by number of cases as soon as they started testing for them (also looks well on its way to overtake Italy and China in the next few days)
Just look at the numbers coming out of New York.
while the UK government has realised that its policy was totally wrong and very damaging and is now scrambling to turn the situation around
Who would have thought herd immunity, implying up to 40 million would have to get it in one region and magically not affect the rest of the world, would be a bad idea...
