Comment Re:"...the same as trespassing." (Score 1) 1197

IR seekers are really easy to make and it's a fun robotics project. Simple to do with analog controls even (the principle is so easy it was highly classified for years). Launch your rocket into the Sun every time.

Tracking a specific target instead of the brightest heat source is much, much harder, but if the drone is the only dark spot in the field of view of the camera, that should be do-able. Fun to try, anyhow.

You have a reasonable expectation that nobody but your second floor neighbors can watch you. That difference is important. You know your neighbors. And even if you don't know for sure that they won't stand at their window and masturbate to you lying next to your pool, it's fairly unlikely due to you easily being able to identify them and throw the book at them.

It's a bit different with random strangers walking by your property. Not only does it multiply the chance of getting a pervert, they are also fairly sure they can get away with perving on you if you don't happen to know them.

Comment Re:Drone fear - Baker Beach (Score 1) 1197

It's kind of the same reaction that Glass wearers got. People object to being filmed in certain places like bars or beaches. If I went round the beach taking pictures of random people, I would be expecting some strongly worded objections as well. And even if the family was clearly flying the drone for fun, those people would still object to the footage being posted to YouTube as "Our outing at Baker beach".

Personally, I don't want to be filmed either... but I don't think it's necessary to be an a-hole about it.

Comment Re:Or... just hear me out here... (Score 3, Informative) 1197

At a shotgun range I've been to, they have a duck tower about 150 yards behind the clubhouse. It's surrounded by a fairly thick stand of tall trees, but a couple of the stations result in shooters shot trajectory going through the "hole" in the trees and raining down on the front porch of the clubhouse.

I've been standing there and gotten "hit" -- it actually feels no different than if you through a handful of coarse sand into the air and let it fall on you, actually less since you really only feel a small number of pellets because of dispersion.

Shooters are restricted to target loads of #7.5 shot or smaller, so its very light shot. So light that on their "hard" sporting clays course it's very difficult to hit the distant crossing and away clays in any wind. The #7.5 shot has so little inertia that it just gets blown off target.

Many pheasant hunters I've known have stories about getting hit with shot from people on the other side of a field or road hunting on roads adjacent to the field they were hunting on. It's like coarse sand, and pheasant hunting uses much heavier shot than target shot.

Also you need negative mass, which doesn't exist even theoretically, oh and more mass energy than the entire universe

Are you thinking of a wormhole, not a warp drive? I'm not talking about a Star Trek FTL drive, but instead a device that warps space, just like gravity does, but asymmetrically. I don't believe it's possible either, but it's still allowed by accepted physics, and it wouldn't require lots of mass.

I don't think we'll know enough about this concept, or about negative mass, to rule them out until we finally understand how mass is quantized, or, rather, where rest mass comes from in the first place. Maybe when quantum gravity is finally understood there will finally be an explanation for rest mass, but maybe it's even further down the road.

Heck, we can't even measure the rest masses of quarks accurately -- not even one significant digit in some cases -- let along explain the values There's lots of physics left to be done there.

Just because i write down math does not make it a valid prediction.

The math of modern physics has been shockingly predictive. All sorts of crazy shit has turned out to be true - so much so that people believed in String Theory for 20 years with no evidence whatsoever (and some still cling to that belief). Those people aren't stupid: "following the math" has a really good track record. It's best to keep an open mind until we get better theories.
