Where does electricity come from?

Saw this on Reddit and it actually does make sense. :hmm:

Electricity comes from electric cars, duh, hello! As the cars roll down the street the rubber tires rub along the road creating static. The static is used by the motor to power the car. The static cling also helps hold the car to the road during cornering.

My physics-major friend insist that magnets are fucking inexplicable magic that no one really understands..

Well, he is right. We know that magnetism exists, that it is VERY closely related to electricity, and that right down to the quark, everything appears to have a north and south pole.

What we don't know is why. Why are there magnetic poles? Why is there an attraction between two opposite magnetic poles? Why do magnets do what they do?

We really don't know the answers to those questions. They just work, and so we use them.

Gravity is much the same way. We have many unanswered questions to why things are attracted to each other.
 
The Journey of Electricity

The electricity we use in our home comes from power stations. It is produced by burning coal, oil, gas or using nuclear energy.
Windmills and gas from tips can also generate electricity. Electricity leaves the power station running at an amazing
400,000 or 132,000 volts. Electricity this powerful would blow up factory machinery and household appliances.
To stop this happening the electricity is reduced in voltage as it travels along.

Yeah, I admitted defeat. But I still hate ICP.

That wouldn't be a terrible price if it were real science. Books are expensive :^/

🙁 not really. Educational books are artificially expensive. Our problem is that there is really only 1 or 2 educational publishers that are taken seriously by universities. As such, they have price fixed and gouged the hell out of their books. Then they use shady tactics like reordering the problem sets and publishing new editions every year where that is the only change (to try and force students to buy new).

Oh, I know. I just meant in reference to the accepted norm. Their days are numbered, and they know it. Free books and learning material will become the norm. That's the way it should be. People shouldn't have to pay for knowledge. Our collective knowledge should be available to anyone who's interested.

Whoa, I just realized it's intended for the fourth grade. By then I was replacing the bad tubes on our TV, built my own ham radio, slot car motor and, had taken apart and put back together the toaster, washing machine and, vacuum. The retired guy next door was teaching me wood working and, the guy up the street, welding. Philosophy aside, these kids are being dumbed down at a point when they should be expanding their minds in all directions.
 
The textbook tries to make electricity seem like a magical substance (which it is in a way- speaking about the fundamental forces of nature) but leaves out the more mundane methods of producing it ie. big coal powered plants by just saying that 'electricity is everywhere'.

I don't have much of a problem with a publisher covering their costs and paying the author. I can accept that price for printed text. What I hate is the fact that while many of the entertainment publishers struggle to get by, these educational publishers proudly gouge the hell out of their captive audience. It is sickening.

This would actually be a place where I would support government intervention to slap the hell out of publishers for the stupid amount of burden they put on cash strapped college students.

Gov't student loans can be used to cover the cost of textbooks. Student loans don't go away in bankruptcy.

So, why would the gov't stop a process that is making money for the gov't?
 
On the flip side I am sure you can find some who thinks it comes from Obama. There is all kinds of stupid all around.
 
I went to private / Christian schools and all my public-schooled friends thought I was some kind of "genius." I was called "computer head" before I ever had any desire to own a computer. I was interested in atomic physics and electricity 6th grade (we used a Bob Jones University textbook that year).

Most of my books were "A-Beka-Book" (curriculum made by Pensacola college). If that picture is legit, it really sounds like it was written for K-5 or 1st grade.
