Comment Wrong Comparison (Score 1) 168

Why should the inheritance of intangible property be treated any differently?

You are making the wrong comparison. Intangible "property" is not property in the real world in which we live, it is simply an artificial legal construct which society created so that artists can make money from their work. If we started thinking about it as a way to reward for work instead of as property we would have a far better system.

I love doing therapeutic massage for people in pain.

That's interesting. I have a friend who's a really successful jazz bassist and makes a really good living doing session work. He went to study massage (shiatsu, etc) for the same reason. He says it has given him a renewed sense of purpose and has made his hands stronger and more dexterous, which is good for his bass playing. I was initially puzzled when he told me he was going to massage school, but now I get it.

m is taken to be the relativistic mass rather than the rest mass.

Relativistic mass is a misleading and wrong concept which even Einstein himself cautioned against. Mass is something called a Lorentz invariant which means that it never changes no matter which inertial frame you look at it in. The gamma factor in things like momentum, p=gamma*mv, comes from the mixing of space and time which means that the relativistic concept of velocity (the rate of change of position with respect to time) in relativity is not quite what we think of in our everyday world as velocity. Hence the gamma factor has nothing to do with the mass and everything to do with the velocity.

An easy way to see this is to try to use it with forces and accelerations: you cannot get away with 'F=gamma*ma' for relativistic forces.

He did not believe the Constitution was a living document to be interpreted with the evolving standards of modern times. And he was wrong.

To the extent that he actually believed what you think he believed, he was right. If you can't muster support for a constitutional amendment, you have no business change the constitution in the name of reinterpretation.


Would You Bet Against Sex Robots? AI 'Could Leave Half Of World Unemployed' 232

Machines could put more than half the world's population out of a job in the next 30 years, according to a computer scientist who said on Saturday that artificial intelligence's threat to the economy should not be understated. Vardi, a professor at Rice University and Guggenheim fellow, said that technology presents a more subtle threat than the masterless drones that some activists fear. He suggested AI could drive global unemployment to 50%, wiping out middle-class jobs and exacerbating inequality. "Humanity is about to face perhaps its greatest challenge ever, which is finding meaning in life after the end of 'in the sweat of thy face shalt thou eat bread'," he said. "We need to rise to the occasion and meet this challenge."

Accurate GPS is good.

But I'd really much prefer a GPS that can work indoors, in cities with tall buildings, near hills and mountains etc.

That seems to have much more uses than getting something from a handful of inches down to fractions of an inch.

My car and phone sometimes get confused about precisely where I am and which turn-off I've taken. And in Belgium (where there are a LOT of underground roads), it barely works at all - by the time it locks on, I've had to go down another tunnel. In Central London, it can lose accuracy just at critical points. But everywhere else it's okay.

Improve the reception and time-to-first-fix. Then worry about sub-meter accuracy. Nobody really uses it for that level of accuracy anyway.

Also let us state it correctly. Einstein did not say E= m c^2. He proved it.

Yes lets state it correctly: it is E^2=p^2c^2+m^2c^4. Only when you are stationary, and so have zero momentum, does E=mc^2. Also Einstein did not prove it. He was doing physics, not maths. What he showed was that given his postulates for special relativity it followed that E^2=p^2c^2+m^2c^4. He was then proven to be correct by experiments not by the maths alone because until those experiments were done his theory might have been nothing more than an exercise in abstract maths.
