If the drone was under 500 ft, in the US there is a potential case for criminal trespass. It's not a slam dunk, because under 500 ft, AFAIK you're really dealing in the realm of common law and precedent. If the drone was over 500 ft, the landowner would be guilty of downing an aircraft flying in navigable public airspace. I believe that's taken pretty seriously.
Even an Ebola vaccine that was only effective for a short period of time would be wonderful. Ebola isn't a subtle disease, and outbreaks tend to start in fairly isolated villages, perhaps because the reservoir is an animal. When someone in a village starts bleeding out of every orifice, administer the vaccine to everyone in the village. That stops the outbreak in it's tracks.
The most popular theory is that it's transferring momentum via virtual particles. That has some startling implications, but it's less physics shaking than violating conservation of momentum. I'm not sure anyone has come up with any solid testable hypotheses yet, but it seems to be something that is likely to be testable in principle.
You'd have to work out the math, but I'd be cautious being too aggressive with relativistic reasoning. Conservation of energy and momentum in special relativity are a bit tricky to start with, and don't hold when you start jumping between reference frames.
They were using a Chrome plugin as a key logger so presumably this only reflects input to their web browser. Not surprising the managers had higher activity than the "developers" either.
If it's not reactionless then you're transferring momentum and energy and momentum are conserved in the same way they are in a regular rocket. If it's actually reactionless then presumably you would find you were harvesting energy from the spatial differences in the laws of physics. Either way, you wouldn't have a perpetual motion machine.
#2 doesn't make sense. The EM drive in all of it's tested and theorized forms uses a lot more energy than you could harvest from the motion it produces.
Noether's theorem doesn't "fall." In this context it says (roughly) that if the laws of physics are the same in all places then linear momentum is conserved. We believe that the laws of physics don't vary with position, but they could.
Also, there are various explanations for how the drive could work without violating conservation of momentum. They require some other interesting violations of things we currently believe to be true, but aren't necessarily.
"Fuel" in terms of energy isn't the problem in a rocket. The problem is the requirement to haul around reaction mass: stuff to throw out the back. If you don't need to do that, the tyranny of the rocket equation goes away and space travel suddenly becomes a much different proposition.
Hm... I took my six year old macbook pro in to an Apple Store the other day. They were happy to work on it. They ran a 24 hour diagnostic, free, after which I took it home and fixed the problem (they would have happily done so). My friend took in his 5 year old one, and they replaced the mainboard in it for free because it was one of the first lead free batches that had known faults.
OS X is a unix-alike. Most of the software that runs on Linux will run on a Mac without a problem.
Your idea of open source seems to be of the double-click variety. There's a LOT of open source software that requires a./configure; make to install. That works on Linux and Mac. If one of the developers is a masochist there might be a way to build it using Visual Studio on Windows, or more likely a way to build it under Cygwin.
Yeah, if my workplace had a dress code I would definitely show up in a skirt during the summer. Also sandals. Cute strappy ones, even if I had to have them custom made in a size 12 mens.
While sweltering at an outdoor summer wedding wearing a jacket, pants and socks (!) I ended up in a conversation with a woman wearing some kind of sheer silk dress and sandals about how men don't understand the social pressure on women to appear a certain way. I told her I would love to wear what she was. She gave me this strange look and excused herself.
If you want to find someone who's going to climb the ladder and be successful, find one of the nicer dressed people. Not THE nicest dressed, he's trying to compensate for something. If you want to find someone who has skills that don't involve telling other people what to do, find the guy who is either not wearing clothes that are as nice, or looks like he doesn't quite belong in them.
MRI isn't the same thing as an inductive charger. The field is much stronger in an MRI scanner, and the main field is static. There are two dangers: having metal objects pulled by the strong static main field, and heating from the varying gradient fields during scanning. Non-ferrous metal generally isn't much of a problem, but if it's easy to remove you might as well. When I started doing MRI research we emptied our pockets but went into the scanner in our regular clothes, jean rivets, zippers, whatever. You'd suggest women might want to take off underwire bras, but it wasn't insisted upon. Regulation creep now means most centres insist on subjects being stripped down to scrubs. Most piercings, dental work, etc. are okay, unless they're near the area being imaged (they can distort the images).
Inductive chargers are lower field, oscillating, and tuned to match a specific receiver coil geometry. You're unlikely to get any significant power transfer to something random like a wedding ring. Especially since the receiver coil is likely much smaller than a finger; you wouldn't want to carry something that big attached to your cell phone.
It's highly unlikely your wedding ring would happen to be just the right size to couple well with the field. If it did, it might get hot, prompting you to remove your hand from the vicinity of the charging station.

It actually does make a difference. 200 feet is potentially debatable. 500 feet + is explicitly public airspace.

They're not even suggestions. They're rules to be broken so you can feel like a good radical.

Carriers have machine and wood shops where they fabricate lots of things, including needed parts for the carrier.

I'm not American. Am I wrong that you aren't allowed to shoot ducks out of the sky in built-up areas?

What correlation? There's just some tech writer who can't do basic math talking about "heartbeat coordination, like in ET."

For outer system stuff you'd use a nuke.

They're difficult to debug (there was a story on Slashdot about a study on that a year or two ago).
The idea of a spreadsheet that needs GPU acceleration is alarming.

68 F is when long pants become marginally acceptable, but still not socks or long sleeves.

There was nothing micro about that aggression.

Lighting some dried up weed on fire doesn't make electricity. Perhaps you should be a little more cautious with your last sentence?
