A little theory

If you are not familiar with Richard Feynman he was a physicist who
worked on the Manhattan Project. He was also a professor at Caltech.
Here are some of his lectures on physics which he offered to
undergrads. Introductory college level physics taught by a master.

Re: A little theory

Not sure how this is applicable to Elecraft list, but...

If you're interested in Feynman's Caltech lectures, a little poking around the net and you can (carefully) find audio files of many of these lectures. They're really fabulous if you like this sort of thing!

Yes, off topic but then my interest in Mathematical Physics comes before
my interest in ham radio (number 1 of my three hobbies).

As an undergrad physics major in the mid-1960s, Feynman volume I was
one of our textbooks and I loved it. But, it was reading only as there were
no problem sets to work on with the book.

We also had access to the 16 mm films of Feynman lectures. I have never
found these film strips available online although there are a number of other
known lectures he gave available on Youtube, but these films we watched
were actually filmed in the Caltech lecture hall as he gave the material from
Feynman volume I.

Yes, Feynman is a good teacher but not the best physics lecturer and teacher
I have heard. One of the best in my opinion is Leonard Susskind and his
lectures are available at http://theoreticalminimum.com/courses

Re: A little theory

In reply to this post by Roger D Johnson

I did meet him. The first thing he said to me was, "Call me Dick", as
he wasn't much for titles. When he was scheduled to give a lecture to
the freshman class at Caltech we were told to arrive early because the
upper-classmen would fill up the lecture hall. In addition to his work
in theoretical physics, he was a master of the bongo drums. A
somewhat-fictionalized film of Feynman's time at Los Alamos is
"Infinity" starring Matthew Broderick.

Re: Feynman - A little theory

Feynman was the adviser of a now-retired coworker, Ben. He told Ben to
give up study of physics unless it was a true passion because that was
the only way to succeed in anything. Ben said he realized this was the
only advice he needed to change majors and later succeed in his new
field. His main regret in doing so was losing Feynman as adviser. Not
exactly related, another retired coworker as a young researcher used to
take a train up to Princeton each month to lunch with Einstein. I loved
listening to stories from these older guys when I was a young, new guy!

Re: A little theory

In reply to this post by Bob Nielsen-4

Thank You Ron for the audio clip.

I’ve seen various videos of Feynman’s work and have enjoyed them. But this audio, in addition to his wonderful NYC accent, brought back a sound I do not remember hearing in the past 45 years. And a sound that is precious (in retrospect) to me - the sound of chalk hitting blackboard. That “leading edge”, the audible signal that something important may follow, is an “attention getter” that physicists and mathematicians will always be attuned to. It can be heard about 2 minutes into your clip.

Thank You!

Re: A little theory

A short story, possibly apocryphal ["alternative fact" in today's
vernacular], that circulated at NASA during Apollo, had Dr. Feynman
lecturing on some subject. At one point, the chalk hit the blackboard,
he wrote out an equation [or something like that] and then said, "This
is obvious, of course." He paused, turned and left the room, leaving
everyone wondering if that was all. A couple of minutes later, he was
said to return and continue the lecture with, "Yes, it is definitely
obvious."

I don't know if it's true but it sure fits his style.

I envy you that Jim. His books (and Ed Purcell's) helped me make sense of E&M to Yale undergrads in the 70's. I still leaf through them.
"What do you care what other people think" was another of his great contributions IMHO.

Ditto on Purcells’s Electricity & Magnetism (part of the Berkeley Physics Series) that I had as an undergrad, I still have my original copy (1965) plus the latest edition updated by Morin and published in 2013.

> My greatest treasure however was meeting Doug De Maw
I will agree with that statement, Doug was a hero of mine when I was in
High School learning electronics and ham radio, I always looked forward
to his articles which taught me so much. And when our high school radio
club had the pleasure of a field trip to Newington Doug DeMaw was
actually there that day, and it was an honor to meet the man who could
describe esoteric circuitry clearly enough so this dumb teenager could
understand it. I felt like some of the joy went out of ham radio when
he passed in 1997.

Interestingly enough as a college DJ at WMUA-FM, at UMASS Amherst, MA
in the late 1970's, and by total happenstance at a concert I met his son
Dave (Douglas David) N8HLE, who was a writer and an awesome DJ at
WWUH-FM, at the University of Hartford, CT. I introduced myself to him
as a fellow DJ, and the second thing I said was that I was a ham and his
Dad was a hero of mine, and he said "Mine too!" Dave was one of the
nicest guys you could imagine, and went out of his way to call me years
later when I was doing DJ shifts on WXYC - UNC Chapel Hill, NC and
compliment the show and talk music...I stayed in touch with him on and
off until his own untimely death in 2011.

Doug DeMaw was one of the greats in ham radio, and judging by his son, a
great father as well, W1FB indeed. :'(

The Berkeley Physic Series is wonderful. But, on a sad note, while I was at Fermi, I worked with Kambiu Luk, a researcher from Berkeley, I asked about that series, he said that it proved to be too difficult. Sigh!

Re: A little theory

In reply to this post by kevinr@coho.net

The link was not off topic when I posted it. My intention was not to
advertise an already famous person but rather to get folks more
interested in learning theory. There has been so much discussion of
grounding, dielectrics, antenna theory, impedance, and feedline problems
which a few equations could solve quite quickly. An equation can
substitute for ten thousand words. The Reflector would not be so
deluged with antenna and feedline questions with just a little more
theory being learned.

I find the ARRL antenna books anecdotal. They give me fish but don't
teach me how to fish. When I learned the antenna equations I found I
could fish any way I wanted to.

73,

Kevin. KD5ONS

Good point. Here is my "theory" on this OT overload thing, Ron. When the
Off Topic contents of the posts become so frequent and overbearing, there
appears to be a direct correlation with a void in new product announcements
from the boys at Elecraft, which normally incite On Topic comments that fill
this space. Perhaps there is something looming on the horizon. ;o)

I forgot to add, if you have any comments, let us take them off the Elecraft

Re: A little theory - speculation on new product?

I was thinking the same thing yesterday. Something is brewing in the
Elecraft skunk works and they're getting it ready for Dayton. That is
keeping Wayne and Eric too busy to play moderator. So let's all go
crazy and guess:

K4? KPA 1500?

Enhancements to the KX2. Adding 160 and 6 meters.
