Who is your favourite electronics guru?

Any Tom, Dick and Harry can copy and build a circuit out of a book.

But it takes a top-class engineer just to look at a strange circuit and describe what it does, how it works.

These days, there are mostly Tom's, Dick's and Harry's! ====================================

Formulated Kron's Law? Invented the Kronotron? Wrote 'The Kronology of Electronics'?

I'm not familiar with any of those.

Do they ?

"Prosaic"? Perhaps. But they ALWAYS work. I posted just a piece of one of my I/C chip designs one time and, IIRC, you couldn't even get a single finger's grip on what it did.

I love to cook with wine.      Sometimes I even put it in the food.

But they aren't true in general, so they really can't be obvious.

Ohm's law, in particular, has some very deep physics underlying it. Kirchhoff's laws are not true for systems where displacement current is important, e.g. the insides of capacitors, or where the system dimensions are not negligibly small compared with a wavelength.

Kirchhoff's current law is a specific application of charge conservation, leaving out the possibility of charge accumulating (as on a capacitor plate). Kirchhoff's voltage law comes from Faraday's law, leaving out the dB/dt term.

And I refuse to do ASCII, so most of my posts are on my website (SED/Schematics page).

Fred, Please work your way down the list and see how many you can explain... in the next four hours, so you have minimal time to request help ;-)

I really like his presentation of the Schrödinger Equation:

Gabriel Kron, Electric Circuit Model of the Schrödinger Equation

Be it right or wrong, to me it is easier to understand a theory when it is presented as a circuit.

Wasn't Kirchhoff first, in 1845? Maxwell published his stuff in 1855-56.

Likewise.

I tried unwrapping it, i.e.:

got the 404, and tried futzing with the page name: which sent me to a page saying there are multiple documents with similar names, gave me another link, and then I got a German 403 Forbidden.

Thanks, Rich
