They say the three basic electronic components are the resistor, inductor, and capacitor. Why are only these three singled out?

And what is the inductor used for in circuits. It doesn't seem nearly as useful as the resistor and capacitor, so why is it included in the big three? What can you do with it?

It's not so much that those 3 are singled out, they are the only passive components (although there is the memristor).

Inductors are used a lot in filters and power supplies.

I notice that my RadioShack Electronics Learning lab manual does not have a project to build a radio. Wasn't a crystal radio a standard project in the 1960's. Isn't it supposed to be easy to build? Why isn't it a part of my electronics learning lab?

Analogue radio is dying out, soon there may be nothing to listen to which would make it more difficult to test. You could always google a circuit and buy some cheap components off ebay

If I had to guess it's because I bet your lab is only concerned with linear components. The diode (crystal) used in a crystal radio is a non-linear component.

True engineering comes from your brain, not a book.

I want want to be able to sit down and create circuits from scratch.

Can you do this?

Okay... except that books (*cough* written matter in general *cough*) are required for you to train your brain to do engineering

Keep studying it and you'll be able to

I think 'experience' is more fitting.

Why is it so difficult for some people I work with to admit they've made a mistake, even when faced with the evidence. What they say clearly does not make sense or match up with the logic of the situation. Yet they continue to proclaim their innocence. How do you deal with it when someone won't admit to what happened. Do you still give them the benefit of the doubt, take them at their word?
