Considering the benefits, bring on the laws that mandate that each stop light wifi/bluetooth/whatever broadcasts its state .

"Here's why, most likely, they always will."

This is an example of Slashdot link text that disappoints. I was expecting some reason or principle why cold fusion will be impossible. You gave us nothing. NOTHING!

However, a thing that is not white *is* necessarily non-white.

Can you model of light explain why it bends 10 degrees (or whatever) at the surface?

Or, how does the atom know to re-emit light in the same direction it was traveling before?

They buy TWO Intels.

OMG, 64 GB of RAM for only $700. That is simply amazing, how cheap it is.

Single thread performance from core 2 duo from 2008, to the 4770 i7 from this year improved just 90%, so, not even a doubling in speed.

That's a strange distinction you are making there. I think your teacher was more focused on memorization of stupid definitions, and less on understanding.

You never know the path of the photon. In fact, it looks like it went trough all the possible paths, including all the splittings and merging. You can not even tell if it went in a straight line or not.

"Physics classes push the difference between "speed" and "velocity" pretty heavily"

You mean, bad physics classes...

"It's more like time doesn't exist as a valid concept for a photon; it just doesn't make sense to talk about a timeline for a photon's frame of reference in the same way that it doesn't make sense to ask what the color red smells like."

Why do you use this stupid metaphor that does not add anything at all?

"When light travels through a medium containing matter it will be absorbed and "stored", for some time, in the exited states of the atoms before it is emitted again."

Then the question becomes, how does the light know how to continue in the same direction it was going previously?

So, when a photon travels trough a optical fiber cable, now does it know when to turn?

Total reflection you say? So, it goes near all those electrons in atoms, and then it only decides to turn once there will be no more atoms in it's current path?

Why is nobody mentioning the fact that the light particle does not take a single route trough space, but travels trough it in all possible ways.

Or in the "Red Queen."

So much time would be saved, and so much more understanding of evolution would be had, if sexual selection was thought in schools. My guess is that this isn't done be because of the word sex in the name.

In the context of the article:

survival of the fittest -> narrows the gene pool
sexual selection -> increases variation in the gene pool

The fist part prunes the "bad" genes. The sexual part actually encourages any "bad" genes that became sexually attractive by any random start.

The examples are peacocks tail, deer's antlers and human brain.
