Language allows you to refine your thoughts. Words stand for abstract concepts that you cannot picture otherwise. Let's use that as an example! How would you think of an "abstract concept" without using those words or any others?

So while instinctive thought can be "faster," it cannot be as detailed. And fast, simple thoughts are not going to be "efficient" when dealing with complex subjects.

[[Edit: Another example: It's easy to picture four things. Four apples. Four cars. Four fingers held up on one hand. It's very hard to picture fourteen million two hundred and four thousand six hundred and seventy five things. You need the precision of words to accurately track and plan around things you can't visualize, whether that's large numbers, complex actions and interactions, sequential events over long periods of time, or abstract ideas.]]

Thinking in words, also known as inner speech, is a normal process for most people that helps us organize and make sense of our thoughts and experiences. It can be helpful for focusing, remembering things, problem-solving, and managing emotions. While it may not always be the fastest way to process information, it is still a useful tool for many people.

Charged particles are coupled to the electromagnetic field. These means that they can change the shape of the field, and if the field is nonzero in their vicinity, they will experience some kind of force.

For electric charges, this picture is intuitive. Two electrons generate an outward-pointing electric field. If they're next to each other, each electron's field pushes the other one away, and they move apart.

Whenever a charged particle has some kind of motion associated with it, it generates loops of magnetic field around it. Similarly, whenever a charged particle has some kind of motion and is in a magnetic field, it will experience a force perpendicular to the direction of the magnetic field. The geometry is a lot more complex, so you can get things pushing on each other at odd angles, but in many cases the directionality of the loops and the forces cancel out, and you get a normal attractive force.

In everyday circumstances, most magnetic fields are associated specifically with electrons. There are three common kinds of motions of electrons. Their intrinsic spin, which generates a dipole field focused on the electron. Their orbit around atomic nuclei, which also generates a dipole field but focused on the center of the atom. And their motion through a wire (or through space, like in a thunderbolt), which generates circulating magnetic fields around it.

Most magnetism you see is some kind of interaction of these three types. For example, a bar magnetic picking up a paperclip. The inside of the bar magnet has a bunch of electrons' intrinsic magnetic fields lined up. The electrons in the paperclip feel this, experience a rotational force to line up their magnetic fields with the bar magnets' field, and then once they're lined up experience an attractive force toward the bar magnet. An electromagnet also generates a magnetic field, but using the bulk motion of electrons through the wire, which also allows it to pick stuff up.

Because you're catching up to the speed of time.

A photon traveling at the speed of light is also traveling at the same speed at which time "happens." Because it's going the same speed as time, the photon doesn't experience time passing at all.

When you go faster and faster, the difference between time's speed and your speed decreases (from your perspective). Should you ever get to light speed, it would seem to you as if time had stopped.

If the test is written by a person, C is most likely. Because the answers are (probably) not 1/4 each.

If the test was shuffled by a machine, and the answers are perfect 1/4 chance, then no strategy is better than any other. Picking straight C is just as effective as picking C most of the time and picking B sometimes, and just as effective as picking with no pattern at all.

We have in our business what I call "Resume Generating Events" or an RGE.

Example: You hear that James has not done backups for over a year and accounting just lost the Sql Database. RGE for James.

This is what you have done is so bad, whatever it may be, you need to go ahead and start printing your resume out.

Double pane windows are required most places nowadays. As to why they weren’t used more in the past, the folks that build homes want to make as much profit as possible in constructing and selling a home. They don’t have to pay the utility bills - that’s on the homeowner. Thus building a house with inexpensive, inefficient windows is better for the builder (or used to be) than more costly, efficient windows.

Platonic forms are imaginary, perfect representatives of a concept. There are lots of different types of birds. However, if we had one bird to represent the "bird-ness" of all of them, this would be the platonic form of a bird. We could also imagine a platonic form of a chair, serving as a perfect example of chairs, capturing all of their "chair-ness".

If there is a set of things, such as birds, then there is likewise a distinctive attribute uniting all the parts of this set--like their bird-ness--and the platonic form of that thing is the imaginary entity that possesses that distinctive attribute (the bird-ness) and nothing extraneous to it. For example, the platonic bird will not be red or blue, since these attributes are contingent and not definitive of bird-ness.

These things don't really exist. But they are similar to the idea of a "prototype" from cognitive science. The idea is that our brain builds up concepts through examples, for example building the concept of "bird" by seeing lots of birds; maybe all of this information is stored in a "prototype" for bird in our brains.
