I agree heartily that math is the toughest for self-study. It is also essential unless you have elected to play in the numeric domain exclusively.
A good tutor can be helpful, also very difficult to find.
I have worked with good electronics engineers who never got the maths down, and you could see how crippling it was. When I started at one company I was assessed for my skills at that moment, and was told of another employee who was described by my immediate boss as "scary". It turned out that the guy, who had a Master's from MIT, had a modicum of math that the boss and his boss had determined was permanently out-of-reach for them, such as being able to do complex algebra and play with simple linear-system transfer functions---although most of the time he just did simulations like so many, and got decent answers.
What disappointed me though: my own skill set in 1990 was hardly static, but I could see that the initial assessment was going to stick indefinitely. At the age of 42 my growth was considered ausgespielt.
This is one reason why the best policy is often to stay in school almost as long as possible, even though ideally one would benefit from "real-world" experience interspersed with the studies. But what frequently happens is one gets some money flowing, upgrades the standard of living, gets married and has kids. The continuation of the theoretical education becomes a receding image that becomes ever less likely.
That may be your difficulty.
No. If you actually believe this, then that may be the other part of your difficulty.
I flat out refuse to do that.
Grow up, that is...
My schooling was more theory and thinking. Not so much rote, but figuring out.
Now, it's more of an immersion thing. It also helps when the work is in front of the leading edge of technology, at least in some aspects...totally heaven I tell ya...

Be specific if you do not wish to state any generalities.
ARE THERE ANY situations where one of these super regs will be audible to YOU vs. a standard "good" 3 pin?
hows that.
And which properly conducted DBTs have revealed anything other than fairly gross differences? Happy to know about them.
Dance, dance, dance...

Apparently you haven't read the article. Or if you did, you've forgotten most of the content. Even your question has a false assumption in it.
Today reading the latest IEEE Spectrum 7.16 I find that most of what I learned in the last 60 years is pretty much passe, but of course it can be still useful.
This issue talked about practical nanotube based computers, DNA based storage, and Quantum research in general. WOW! Maybe Bybee is on to something. '-)

That cannot be true. The total flux around a closed curve is given by the total current going through the area enclosed by the curve. If the current is mostly at the surface of the wire then inside that surface there must be very little flux. Basic first-year EM.RNMarsh said:
It is true that some EE profs lack practical experience in electronics. That does not mean that their theoretical teaching is necessarily wrong or irrelevant - although sometimes it is, and needs to be corrected by the correct theory as found in the better, more advanced textbooks.davada said:
Ditto.. Textbooks were de-emphasised, it was all about experiments, learning the methodology, writing your own textbook, more or less...
One of the best things you can learn is how to learn efficiently and effectively. How to define the problem you want to solve. How to attack it.
That is an ability you can use for the rest of your life no matter what you are going to do.

I just read that too. Nothing in there to undermine my education, and nothing to support the Bybees of this world. Maybe you saw a different version from me?john curl said:
Good -- thanks for the comments. I thought it seemed fairly good, but after some of the dialogue here you start to wonder... And wiki can be a tad variable... 🙂
The generally dismal level of engineering education today leads to what I call app note designing, essentially stringing together application notes in a cut-and-paste fashion. Even with this, which is done to speed up the design process and assure success, and please managers, things still go wrong. There is not a lot of innovation, which suits the suits, at least for a while.
In the proverbial good old days, people who entered electronic engineering school were already experimenter/hobbyists. Even other disciplines like physics and astronomy had undergrad and grad students who were handy with gadgets. By the time I started to work for UCLA on the nonacademic staff, there were only a couple of people in the astronomy dept. who were comfortable with such things, and I was hired in because one of them was doing too much gadgetry and not getting his dissertation done.

Page 29 of the IEEE Spectrum 7.16 mentions a paper that Jack Bybee recommended to me about 15 years ago. Here it is. I would never have been exposed to it without his input. It gave me a 15 year head start so to speak on electrical conduction compared to many here.
Anybody can contribute to Wikipedia. It sounds like you have something useful to add...
What is even more interesting, is I can duplicate it with insulated magnet wire.
By using a straight length of magnet wire and immersing it in mercury, the conduction remains the same after initial contact, no matter how deep I push the wire into the metal. Clearly, a length of magnet wire will exhibit quantization. So I can make devices with copper powder and sell a lot of them at high cost, right??
The researchers have lots of work left to do. Ballistic electron movement is consistent with vacuum tubes as well as superconductivity. The problem with ballistic transport is not in the middle, it's at the end..
If you want, just ask the researchers of the paper about bybees.. However, a warning. Do NOT ask them at lunch, especially if one of them is taking a drink. Fluids coming out the nose is not a pretty sight.

I may yet have to. At this time, I have other more pressing matters to attend to.
Maybe in a year or so.🙁
