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.

"Why spend a shitload of money of a new 4K screen and the video card necessary for an acceptable game experience when I'll be able to do VR with a fraction of the cost and with my existing hardware setup?"

Oh boy, somebody is going to get very disappointed.

The word "flat", it doesn't mean what you mean it means.

I would recommend an excellent book "The Red Queen" by Ridley.

It explains why sexual selection pushes many organism features that are in fact handicaps for survival.

Human brain has all the characteristics of a feature evolved to be a handicap. It uses 40% of total energy, it evolved quickly, and we seemed to survive without it being such a big organ before.

Once you have a large brain and language, it becomes harder to just look at the genetic evolution, since it becomes a genetic/memetic evolution. And it is this person/culture complex that is seemingly most evolutionary successful thing.

One could also argue that is it in fact bacteria that are evolutionary most successful organisms on earth.

I would agree that it is hard to argue that a huge brain is a survival handicap. It may have started that way, but it got useful in all sort of ways. And also, we all look at this problem from the brain's perspective, since this is what we actually are, and not from the genes' perspectives. Also, being in a long non-food crunch situation also makes those 'details' hard to see.

Or if it is coming, it is coming in the form of a simple single cell size, frozen in space, riding a simple rock. Perhaps that is how we got here. (plus the 3 billion years of evolution.)
