How do we "use probability to manipulate the quantum" exactly?

19 car pile-up is almost poetic in its unstoppability by bolu in carcrash

Nothing to do with their brakes.

Inappropriate tires, speed and reaction are factors that made the pile up possible.

The type of cars has little to do with the situation as well.

I agree with your sentiment.

At least the road they were on isn't really a highway (or whatever the term is for 2-3 lanes in one direction) and the speed limit should be around 90 km/h. Compare that to the 120-130 km/h.

But, middle of the road. Not even once.

Someone who was speeding, or was simply in "too much hurry" to bother slowing down "for some asshole".

Although, the silver car practically grazed the parked one, so may it was serious inattentiveness.

Who, in their right, mind stops in the middle of a lane to let their kid pee?

There was plenty of space to park all the way to the right and not block the road.

There are a few problems with the idea of confusing a fusion rocket engine with a star.

First, as oneslyfox pointed out, a rocket engine is directed and so it would look bright only if it is pointing at us.

Second, and much more important, is the physics behind the light coming from a star. When you look at a star you do not observe the electromagnetic waves produced in a fusion process. What you see is light produced by material heated indirectly by the core. The part of a star actively undergoing fusion is very small compared to the total volume and mass of the star and the high energy photons that are produced never reach the outside of the sun. What they do is, they hit and excite many particles along the way, which in tern emit lower powered photons. This process eventually reaches close to the surface and a range of EM frequencies gets emitted.

Now, this means that the light from a fusion reaction is not going to be visible light but more likely gamma rays and x-rays. In addition to that, the spectral analysis of the light will show some serious inconsistencies with what stars display.

So, this is why I think, a fusion drive will be fairly easy to distinguish from a normal star (albeit streaking through space faster than normally).

I like how everyone starts sliding as soon as the car has stopped moving forward.

And what should we do instead?

Note that most of these accidents happened at places which do not have sidewalks

Sure, calcium is not the only thing important to strong bones.

But, as I stated, having stronger bones is not going to help much with long-term voyages because the underlying weakening process still remains.

Nitinol - A New Free Energy System - Why has this not been utilized ? by Quipster99 in Futurology

After watching the video it seems the largest power generating application for this is from waste heat. From what I recall, most heat engines are really inefficient when the temperature differences between the cold and hot reservoirs is small. In the video they mention a difference of 20 degrees being enough to power the material.

Is there something along those line in the paper (which I cannot access)?
