@Qurtyslyn: Yes

@MisterHister: Choice of notation doesn't alter the expressive power of a theory, only impacts its accessibility. Anyone who thinks Einstein notation is a good idea has taken a severe blow to the head.

@Settings: No, you're not going at the same speed. Light is always travelling 299,792,458 m/s faster than you are.

I don't understand the point of this case. Why not just use a laptop? In my long experience with laptops, I've almost never had to worry about the screen falling off.

I'm sorry, physicists, I'm taking away your toys. No more playing around with infinity until you learn how to take care of your math.

@OgilvyTheAstronomer: Good reasoning. Heartclick.

@Settings: Your headlights are stationary relative to yourself. They'd function exactly the same as they do when you're driving down the road.

@MysticBiker: The man is infamous for parking in handicapped spots, because he doesn't think he should have to walk farther. Or is that simply elegance of parking?

@jdale: Yes, but Gates' house was interesting from a tech perspective. It was, and presumably still is, a gadget lover's dream. For example, it recognizes occupants and automatically adjusts rooms to each person's desired temperature, humidity, etc...

@cntyglghtly: Yes, but Jobs has only a tenuous grasp on reality. The first 'Laptop' as we recognize it today was the Grid Compass. Here's a picture of one on the space shuttle, 5 years before Steve Jobs 'invented' the Laptop.

@luke.timothy: Basically, yes. The might cause some heating, but the effect is pretty minor. A cell phone maxes out around 1 watt. In comparison, a microwave oven operates around 1500 watts.

@sip | bearstronaut: Indeed. Although I'll point out that, as far as EM radiation is concerned... UV kills far more people than gamma rays.

@sip | bearstronaut: Gamma rays are electromagnetic radiation. It's alpha and beta "rays" and neutron flux that are the major non-electromagnetic forms of radiation.

Electromagnetic radiation has been understood since the 19th century. The interaction of electromagnetic radiation and matter has been understood since the early part of the 20th century (that's what Einstein got his Nobel prize for, 90 years ago).

@Arken: I approve of this message.

@S1L1SC: Reread my comment, and then go think about what you've done.

@Segador: Power isn't really that problematic, but there is some engineering work to be done. The key is to forget about batteries and use either a fuel cell or a microturbogenerator.

@mynamesafad: Yes, but they do that to appease the drivers' union; there are plenty of fully-automated light rail systems in the world. Having a dude on a dead-man switch doesn't usefully improve safety.

@icelight: There were promising results with H2S on mice, but if memory serves me correctly, they started encountering serious problems when they tried it on larger mammals.

Humans will still be at the controls long after the technology to replace them entirely becomes available. People are irrational.
