Exams-time here.. Not particularly struggling with any of the chemistry og biochemistry parts. But there's so much detail to pay attention to.
College was too easy for me, except the circuits and electronics classes because they couldn't give me a straight answer on where the hell the energy came from. The answer is always magnetic flux by the way. Power leaks from a source so tny we've never seen it's parts. It's unbelieveable that that is the case. Think about this guys. The sun moves planets. We move moons. I can defy the tremendous gravity of Earth's Magnetic core with a cheap fridge magnet. Do you know how much power that takes? The components in a stereo are rated to handle no more than 10 watts ever, but more likely a single watt...how does that become 1000watts? The speaker powers the device.
The schools complete failure to disclose this information because they were never told themselves is frightening. Electronics operate in 4 dimensions (well, more but the 4th has more power than it is possible to use) however science is stuck in 3d and the observable world regardless that you demonstrate the functionality. I can't prove my speaker is providing current, so I guess when the did it the first time they thought the massive amount of useless current they fed in was the reason. Bullshit. There's more current in a small speaker than a nuclear power plant exploding a million times. You just have to pull it out where it is infinite and replenishing like a current, not the self destructive system we have developed.
Back in the early 1900's they explained that there were two hot poles in a circuit always. positive, negative and ground. eventually they dropped the negative (only to bring it back when they realized that electrons were negatively charged.) This left a huge mess in the theory. Basically, having that pesky, but critical extra pole made the math so difficult few could follow it. With the extra hot pole and hard to grasp nature of subatomic physics, the problem is confounding. The only answer is literally "magic" until we can build something that can see millionths of times small than atoms.
