Someone else replied already and explained this, though that seems to have attracted a troll of some sort.

Basically, the idea is that people on bikes have better awareness of road conditions as they should be traveling cautiously at lower speeds and aware of their surroundings more than a vehicle driver would be. They can therefore approach an intersection with a stop sign the same way a driver in a car would a yield sign:
1. Slow down, checking for traffic in all other directions
2. If there's no other traffic, proceed without coming to a complete stop

Moreover, it can actually be more dangerous for a bike rider to come to a complete stop. It is much slower for a bike to accelerate from a complete stop than from a slow yield. That puts the bike rider in the intersection for longer, making it more likely that they'll be hit by someone speeding along in another direction, who was out of sight when the biker started. A car in this situation can gun it; a bike rider in a low gear just gets hit.

Next, it's safer on bike riders to take back roads than it is major arteries. In my area, bikers can take the main road with all its traffic and traffic lights, or they can take one of the collector streets in my neighborhood. If they take the main road, they might not have to stop as much, but they are more likely to be hurt in an accident. The neighborhood collector has a lot of stop signs, but if they can treat those as yields then they can take it also without stopping much and be safer due to less overall traffic and slower car speeds.

Finally, not every biker is in tip-top shape. Letting them bike without having to restart from a complete stop as often makes it easier on the biker, which keeps them biking, which is healthier for them and might take a car off the road. For people who don't give a damn about biker safety, but hate sitting in traffic, this benefit is for you.

This is incorrect.

If you are standing at sea level in a cave deep inside a mountain, acceleration will be less than 9.81 m/s^2. That's the point of the article. The mountain above you is pushing down into the mantle, displacing denser mantle material, so between you and the core is less mantle than if you were on a boat in the sea.

The question is, would he have done this even if not running for president?

The answer is obviously yes, based on past behavior. Rand Paul has been one of the few people willing to go on record voting against things he does not agree with, instead of not voting at all.

So while of course some element of it is PR, that is not the core reason as to why he did this.

Which is doubly annoying/funny because Google, at least, doesn't give people brain teasers.

researchers say that's up for interpretation

What good is a law if it cannot let the government arrest Sandor silence anyone arbitrarily based on the prevailing political winds?

Why not an RC Zeppelin with nuclear RTG powered fans, that also uses excess power to generate replacement hydrogen from ambient moisture.

Now THAT sucker would be up there forever. I'd live in one if I could.

The website you get following the "hydrocopter" link in the article states pretty clearly:

HYCOPTER is being readied for a record flight endurance of 4 hours, or 8 to 10 times the average flight duration of equivalent systems today.

Which is about right based on even high-end drones consumers use today.

The article has a picture of the CURRENTLY WORKING drone. It doesn't have large tanks of anything, it has two small tubes of hydrogen.

I think you have greatly miscalculated the pressures needed by this system. It's not storing pounds of the stuff, just 4oz or so across two fairly large tubes...

I did - the facts are that the Clinton foundation claims to be a charity, but uses almost none of the money collected for charity. The facts are that the foundation gained a huge boost in donations from people while Clinton was in the state department, from people/governments who had matters being decided by the state department...

If you want to ignore the facts, fine. Just don't claim to be for them at the same time.

Sure, if by "never contacted" you mean "given lots of money, along with other people on the panel, to vote a specific way".

Are you really so naive? You don't even have to dislike the clintons to understand the fundamental flow of money involved here and just how easy it is for that to have an effect on the results.

It's also stupid on the face of things to claim Clinton had no influence when donations to her charity fell drastically after she left the state dept... You don't need a tinfoil hat to pick up the subtle single there.

You missed the point, I think.

The bionic foot in the article doesn't receive signals directly from the brain. It receives signals as they arrive at existing muscles. So we're talking about a brain that has already been wired naturally to control normally-grown muscles, and hijacking that message to also actuate motors. To use this process for additional limbs, you'd have to have a person who had grown those limbs to begin with.

They need to rewrite the law to allow bikers to treat stop signs and yields, and to treat stop lights as stop signs.

Of course that doesn't work at a busy intersection where the bike cannot safely cross without a green light, but it's a good start to making biking more efficient for bikers.

Yes but in the 90's you burned CDs of 80's songs.

and even hand-burned CDs of stuff you downloaded way back when

Just casually tossed out at the end there... when in fact that was the primary goal.

He wants to build the largest collection of 80's Mix CD's EVER ASSEMBLED, probably for some kind of evil sonic weapon.

Well sir, you will have my CD's and my wishes for luck in whatever scheme you have hatched, I ask only that you spare me or at least email me beforehand when to put on earmuffs.

SolStats shows a chart from UK Department of Energy and Climate Change, that says UK electricity prices have jumped 50% higher than five years ago

Just curious which one of you is lying - the UK trying to scare people into buying more alternative energy as ,energy prices rise (though of course they don'y say WHY they have risen...) or you trying to avoid scaring people from realizing wind power is quite a lot more expensive?
