What is Reddit's opinion of Pleasure of Finding Things Out: The Best Short Works of Richard P. Feynman (Helix Books)?

From 3.5 billion Reddit comments

I only knew a bit about Feynman when I picked up The Pleasure of Finding Things Out. He has really head scratching essays and stories that are written in a very conversational tone. Ever since I had him on my list of people living or dead you would want to have dinner with.

If anyone is interested in more Feynman, I suggest checking out The Pleasure of Finding Things Out: The Best Short Works of Richard P. Feynman (links to Amazon). He had a fascinating outlook on life and learning.

Why would learning about reality be depressing? Feynman even wrote a book, <em>The Pleasure of Finding Things Out</em>.

This is how Richard Feynman's father was with him and how he was with his kids. "Dad, why does..."? "How does...?" "Let's find out!"

I will not rob you of the joy** of finding this out yourself, googling for web pages that contain the three words

• schmitt trigger oscillator

except to say that (this YouTube video) is excellent. It was Google hit #3.

AFTER you understand how Schmitt trigger oscillators work, you may appreciate that you'll get best performance if the square wave input swings symmetrically above and below the input switching threshold. In practice this means you will want to make an RC timing network out of one capacitor and TWO resistors, because the input switching threshold is a constant number of volts above ground. It's not a constant percentage of supply.

Let's wait another few weeks, and let the upvote/downvote counters stabilize. There's no rush.

If you're interested in "pre-CMOS" then that would be before 1968, which is when RCA sold CMOS ICs to the commercial (non-military) market. (citation)

The good news is: back then, the IEEE Journal of Solid State Circuits only published 4 issues per year, so it won't take you very long to simply read the table of contents of every issue. And the International Solid State Circuits Conference annual digest was very thin. See if anything remotely similar was published, pre-CMOS. I happen to know the answer already, but you will enjoy the experience of discovering it yourself. Feynman agrees: (link)
