I wish this comment was more representative of my personal experience in science.
Instead I got PIs happy to say that weak evidence "proved" their theory and to try suppress evidence that negatively impacted "fundablity". The most successful scientists I worked with were the ones who always talked like a PR puff piece.
The issue is not really with the difference in impact between drone attacks and other types of aerial attacks, but with the dramatic increase in scale, resulting from reduced cost and risk.
It probably would have been more accurate to say something like "mass extra-judicial assasination/execution of individuals opaquely labelled as 'militants,' including US citizens, in foreign jurisdictions" instead of "drone strikes," but the latter is shorter and I thought would be understood as implying the former.
They invaded two countries simultaneously (one landlocked). Then used secret stealth helicopters to fly a hit squad into an allied nations territory for one particular individual.
I don't think this is a fruitful debate but I doubt risk & cost are as much a determining factor as you'd like.
Using something similar to a benzene ring with spokes sticking out of it is absolutely a reasonable choice for depicting sodium hexametaphosphate in a schematic. This is actually a pretty common choice in scientific literature regarding this molecule.
If you look at it more carefully, it isn't really a benzene ring, though. It's got multiple layers to it.
And the neural net crossover is just wrong. Really, really wrong.
This is nominally educational content. Any way in which it is wrong is something that people can and will pick up on and form incorrect assumptions about which they will carry forward. It's not enough that it is vaguely sort of, if we're generous, isn't entirely wrong. That's not the bar for human work either.
Do you really think the engineers building a robot to go into Fukishima have never once looked at the first handful of google results for "radiation hardened camera"?
A more generous reading of that comment would be that it’s other things not the camera’s that are causing the problem.
A CCD image sensor that’s lost 20% of its pixels could still be providing useful information, especially if you’re just trying to get the robot out. Other systems may inherently have issues long before that point.
I believe GP is a riff on the common joke among physicists: "Anyone who claims to understand quantum mechanics is either lying or crazy."
To be more specific in the case of magenetism, you can say that, for example, ferromagnetism arises from the alignment of magnetic moments into cohesive domains, where the individual magenetic moments arise on the atomic level from unpaired electrons in the d or f orbitals.
But if you poke at that (incomplete) answer a little bit, things start to get complicated. How exactly do magnetic domains align? What if there's a disruption in crystal structure? Are there other sources of magnetic moments? Where does the magnetic moment on an elementary particle come from? The answers to these questions get pretty complicated and questions like these motivate a lot of active scientific research.
