Love Hurts (or What the Cat Did)

I know he looks all calm and peaceful in that above picture, but the cat and I have a rather contentious relationship. It's not that we don't like each other, either. In fact, the cat likes me rather more than I'm comfortable with. That doesn't stop him from threatening me with laser eyes!
No, just kidding. He never threatens. It's just a "do or do not" thing. Okay, fine! I'm kidding!

I think...

I mean, he's never shot lasers at me, but that doesn't mean I don't think he could if he wanted to.

Actually, the problem really is that the cat has a great amount of affection for me. So much so that during the middle of the night, as I've spoken about before, he will decide he needs me to come and just sit with him. He wants to hang out in the living room and stare out the window, but... it's like he's scared to be alone in the dark and needs me on the couch. Sometimes he comes and sleeps on my lap. Fortunately, now that it's colder, he's been pretty content to sleep at the foot of the bed and not worry about the window and what might be out in the dark.

But that's not what I want to talk about...

The actual problem is that one of the things cats do to "loved ones" is groom them. Have you ever been groomed by a cat? Let me just say: it's not a comfortable experience. If you want to know what it's like, go buy some sandpaper. Of course, I'm assuming you don't just have some around. When I was a kid, we always hand sandpaper on hand but, then, my dad had a tool closet full of all kinds of stuff that he never used. Including sandpaper. Because, if anything needed to be sanded, that was my job. Anyway... Go get some sandpaper and tear off a piece about the size of the end of your pinky finger. Now, take that paper, find a place on your forearm, and stroke that piece of paper in the same spot on your arm for, say, five minutes. Can you do it? No? Hurts, doesn't it? Imagine that going on for half an hour.

It leaves abrasions on the skin just like the kind you'd get when you were a kid and fell down on the concrete. The next day there will be little scabs all over in the patch of skin that he groomed, and it hurts for a couple of days. One time, he did it to my collar bone, which didn't hurt while he was doing it, but it left a mark that looked like a hickey. heh My wife wasn't amused.

Speaking of my wife, she always asks me why I let him do that to me. Her position is that I ought to just throw him off of me when he starts the grooming behavior. And, well, maybe I should, but I look at it like this:
When a baby grabs your beard... Oh, you don't have a beard. Okay, ladies, when a baby gets a fistful of your hair in its little baby hand and starts flailing its little arms around, do you throw the baby on the floor? Only if you want to be charged with child abuse, right? Yeah, yeah, but it's a cat; it's different. The cat will land on his feet.

But it's not really different. The cat doesn't know what he's doing. I mean, the cat doesn't know he's causing me pain. It's like if your kids make you breakfast in bed for your birthday and, then, sit there and stare at you so they can watch you eat it... and it's the most terrible sawdust you've ever put in your mouth. But you eat it anyway. For love. Well, so as not to hurt someone trying to show you love, because I am not saying I love the cat. [Trust me; if I had to pick between the cat and the dog,
I'd dropkick the cat out the door before you could count to three (don't tell the cat (though I suspect he already knows)). But that's beside the point.]

Which brings me to the point:
Sometimes, we do painful things for love, our own or someone else's. Even though we know whatever it is will be painful, we do it anyway. And we should. Intent means a lot. Basically, I don't want to punish the cat for something he's doing for the right reasons, even if it does hurt, and that's how we should be with people.

Oh, and by the way, I tried to take some pictures of the wound on my arm after the last time the cat did that to me, but my camera got confused by all the hair and couldn't figure our what to focus on. Maybe next time.

The A to Z of Fiction to Reality: Lasers

It's quite possible that I should have put this post under "E" for "energy weapons," but, see, I really love the idea of the exo-suit, so I couldn't leave that out, and it's lasers that most people associate with energy weapons, so I figured I may as well stick with it. This one is going to be a bit more convoluted than the others, though, so try to keep up. This way, please...

Let's first step back to 1898. Martians were invading the Earth. Well, at least, they were in H. G. Wells' The War of the Worlds. The Martian's tripods were equipped with heat rays that they used to destroy, well, everything. This is the most significant early example of the raygun. It may not have been the first (I don't actually know, but I couldn't find anything earlier), but anything that was earlier has been mostly forgotten.

Rayguns in fiction became increasingly popular through the early 20th century. In fact, they sort of became standard fare in pulp science fiction including Buck Rogers, Flash Gordon, and others. They also became pretty standard in comic books.

Then, Einstein happened...

Well, let's re-examine that. In 1917, Einstein put forth the Quantum Theory of Radiation which established the theoretic foundation for irradiating light waves. It's this theory that would later lead to lasers. But, in the meantime, rayguns flourished in fiction.

And, now, we're to the part where, maybe, this entry should have been placed under the letter R. Prior to World War II, there was research going on to develop rayguns (in the United States, at any rate, and, possibly, in Germany (actually, probably, everywhere, but I don't have that information)). That research coupled with some of Tesla's ideas (also from 1917) lead to the development of radar.

But we still didn't have any rayguns.

Finally, in the '50s, the first significant breakthroughs in laser technology began to happen, and, in 1959, Gordon Gould published the term L.A.S.E.R. (Light Amplification by Stimulated Emission of Radiation). The first operating laser followed in 1960. Science fiction went crazy, dropping rayguns for laser guns. But only for a moment...

One interesting factoid about that:
The original Star Trek had two pilot episodes. I bet some of you even knew that. The first pilot episode, "The Cage," was produced in 1964 (and remained unreleased until 1988) and included lasers. The first pilot didn't convince the studio that the concept would work, but they were still intrigued by the idea, so they made the odd request for a second pilot, "Where No Man Has Gone Before." The interesting bit? It had already become apparent by the time of the 1966 production of the new pilot that lasers were not going to be practical as guns or weapons, so they changed the name of the devices in Star Trek to "phasers."

But the military really wanted laser weapons, and science fiction continued to be full of laser type weapons even if they didn't call them lasers. Star Wars got blasters, Doctor Who had stasers and all sorts of other things, and Starblazers got a wave motion gun just to name a few. And the military... well, they made this big laser and mounted it on the top of an airplane and sent it up to shoot down drones or something. But it was a cloudy day, and the clouds totally dissipated the lasers, and the project was mostly dropped (and, no, I can't tell you where I got that information (yes, if I did, I would have to kill you)).

This, of course, did not stop Reagan from creating the Star Wars program in the '80s. That almost did work; they just couldn't get enough range out of the lasers for them to actually be effective. But it did lead to one of my favorite movies of all time
Real Genius!

So... here we are in 2012, and we still don't have laser guns or flying cars. Or laser guns on flying cars. I do expect the flying cars soon, but it looks like the closest we're going to have to laser guns for a while is laser sighting. Sure, you can put someone's eye out with it if they agree not to look away, and we can cut things with really big lasers, but they're not really portable at that level and need huge amounts of energy.

But let's go back to rayguns... actually, let's go back to that very first one: H.G. Wells' heat ray. The military rolled out the first example of the non-lethal Active Denial System in 2010.
What we have here is, basically, the realized form of Wells' heat ray. It works by directing microwave energy at the victim causing the skin to attain a burning sensation. Most test subjects reach their pain threshold within 3 seconds, and no one has gone beyond 5 seconds. At the moment, it's being used as a non-lethal weapon, but there's nothing to keep it from being used in more lethal ways if the government wanted the development to go in those directions. The one mounted on the humvee above is for crowd control, but they are working on portable devices.

There you have your fiction to reality, just not with lasers. But lasers still power the imagination, and militaries around the world are still working on laser-based weapons. There have been claims of ground-based lasers that are capable of taking down aircraft, but they require enormous power sources. Interestingly enough, other uses of lasers have stayed pretty confined to science, not science fiction; however, if we ever do make it out into space, I would expect the weaponized use of lasers to reach science fiction proportions almost immediately since there are no atmospheric conditions to deal with.
