What percentage of homicides and violent crime are related to gang activity? Take Chicago for example as it continuously pops up in the news. I would contend that better mental health care does nothing for them.

I take a broader view of mental health besides just treating pathology. I see it in more holistic terms, that involves poverty, debt, external stress, family life, even nutrition and physical health. People without purpose in life can find purpose.

There's a reason you don't find violent street gangs in Lake Forest or Kenilworth which are as close to downtown Chicago as the far South side. And before the ACs jump in, no, it has nothing to do with the properties of race.

So, you seem to be saying "millennial", except with a lot less words. Are you a 49ers fan? Colin Kaepernick might want to use your argument, he's a jackass too. Not as bad as Carlos Danger or Hillary Clinton , but worse than Chris Brown. yeah Colin should fuck off and so should you.

would you propose the same solutions to preventing suicides as homicides/violent crimes?

Yes. Better mental health care and sensible restrictions on guns.

Not having ready access to a gun might have given some of those suicides a chance to reconsider. A Harvard study says 9 out 10 people who survive a suicide attempt do not go on to die by suicide. But it's pretty hard to survive a pistol shot through the roof of the mouth, you know?. The vast majority of people who attempt suicide by means other than handgun are not successful. The success rate for the gun users is well over 90%.

Regarding homicides and violent crime, you are much more likely to be shot to death in a violent crime than beaten, stabbed, strangled, impaled, poisoned, hatcheted, smothered or thrown out of a window combined. The National Institute of Justice says that nearly 70% of homicides are committed with firearms.

Isn't it a bit misleading to lump 20k+ suicides into that figure since they happened to choose a firearm to do it with?

Not at all. I'm comparing danger. As an American, you're over a thousand times more likely to die from the bullet of a gun held by an American than you are to die from anything ISIS does.

But you bring up a good point about suicide. Americans are thousands of times more likely to be a danger to themselves than they are to have ISIS be a danger to them.

So why all the fuss?

Which is my point about how we should view the Tesla autopilot, and even you agree that you are capable of that level of attention.

The tesla is only used on thie highway, and it generally drives perfectly fine. Do you think the guy who ran into a truck while watching Harry potter would have done that if the car drove like it was under the control of a brand new novice driver? Of course not, he'd had the car for quite some time, and had many hours experience letting it drive and it drove just fine.

While he SHOULD have treated it like a new driver; hour after hour, mile after mile of it doing everything right -- you won't stay in high alert. You can't. New drivers constantly trigger your high alert attention with their jerky movements, lane positioning, and other issues... if they do everything right for 3 months, you simply are not going to be on constant high alert. Its just not human nature. At best you'll be paying attention the way any relaxed passenger does; if your sitting there looking out the front window you'll see things, but that is NOT high alert. That is NOT ready to take over with instant notice. And if something distracts you, you'll be distracted because the driving is taking care of itself.

Sure, you absolutely can avoid going full retard and firing up a harry potter movie, and sitting in the seat passively watching the world sail by is going to catch a lot of tesla's mistakes. But if it misses a bend in the road and slams into a gaurd rail or crosses into oncoming traffic... that's going to happen FAST. And unless you are sitting there at high alert almost expecting a mistake like that, you won't react fast enough. And you can't sit on an interstate crossing the country for long stretches ready to jump in like that.

The average human being isn't wired for that.

The average human being can drive the car for long stretches because the constant micro adjustments continually engage them.

Scientists have written papers on this stuff.

Once I feel that the Tesla autopilot has "mastered it" through software updates and the like, then yes, I'll pay much less attention. But just like with a kid learning to drive, that won't happen until it's been proven to have mastered it.

Again... the guy who ran into a truck watching harry potter didn't buy a tesla and then pull out his DVD player. The car had convinced him, through thousands of miles of demonstration, that it was perfectly capable of driving itself,... until it wasn't.

I imagine that the sporadic attentiveness that you speak of is a direct result of knowing or assuming that the driver has everything under control. But, that's just it, no where has anyone said that the Tesla Autopilot has everything under control 100% of the time.

The car gets it right enough of the time, that it's proven to these owners that it does. If it made lots of little mistakes every time people turned it on people would pay at lot more attention.

If it manages to violate conservation of momentum and that stands up to the inevitable scientific pig pile that follows, I'll be impressed.

I am not a physicist, and don't *really* understand what they are theorizing, except that they are suggesting that special relativity applies to the engine instead of newtonian mechnics. (which isn't really a surprise).

If you can follow the math and the judge the theory, have at it...

The amount of attention required, which is basically just keeping an eye on the road and what's going on around you, is exactly what is required when teaching someone to drive.

A 'driving instructor' scenario is quite different; for starters its their paid job to *evaluate your driving* -- which is very different from being a passenger. So they are constantly evaluating your speed, control, position and how you perform each manuver; they may be taking notes on it. They do it for 20-30 minutes at a time, with breaks, usually in city traffic, etc, etc.

They aren't doing it for hours on end on road trips.

As a parent teaching a child, if they are still new then yeah you can be very attentive because you are basically driving as surrogate through them and they are doing all kinds wrong, but once they've pretty much mastered it, and you are comfortable with their driving and your just in the car so they can practice, your mostly a passenger and just at heightened alert sporadically or if you notice something; or are trying to help them with a particular maneuver.

It's what I do when I'm a passenger in the front seat of the car, for hours on end. It's exactly what my spouse does when she's the passenger and I'm driving, for hours on end.

That's just it, no your not.

Your are sporadically attentive and you don't even realize when you aren't being attentive. Yes, my wife will call out a light change if she thinks I'm not reacting to it, or a cyclist if she thinks I might not see it, etc, etc. But she'll also send text messages, look something up online, play with the radio, space out and look out the window.

I definitely appreciate that she's a 2nd set of eyes; and she absolutely makes a positive contribution the total situational awareness, and i don't even dispute that some of the time she's 'ready to take over', but not 'every minute of every trip', not even close. She takes breaks from paying attention all the time; she'll be on higher alert in a new city in weird traffic when helping me navigate; but on some highway we've been on a hundred times...she'll pull out her phone and see what's playing at the theatre without giving it a 2nd thought.

Comment heat (Score 1) 404

While there may be no mass escaping from this device, it absolutely is consuming energy. Where does that go?

In most of the mundane pursuits we understand, it goes to producing heat. In physics, one fairly valid viewpoint is that heat is motion, in that a "hotter" result has more motion activity going on at the particle level.

One of the reasons that perpetual motion is impossible is that within a closed system, we can't make anything 100% efficient. Typically the lost percentage wanders off in some fairly easily identifiable thermal guise.

The first thing to keep in mind is that not all energy expended does useful work.

But that's not really the problem here. the problem is that motion in space, as we understand it, depends entirely on imparting momentum to something. The only way we have practically been able to do that is to send stuff out one end of a spacecraft, which causes, due to the equal and opposite rule of newtonian physics, the spacecraft to go in the opposite direction.

But it's not really about "where does the energy go." This thing is being sold as "doesn't send stuff out one end of spacecraft" and "imparts momentum." The physics folks are looking at that claim very dubiously, because so far, there's no generally accepted science that could account for such a thing.

If it turns out to be a real effect (and I'm not saying it will), then we're going to have some new science to learn.
