The first task could be done with a tool like this, but it is not a project for beginners. The second requires a different tool, a non-sequential ray tracer. See https://community.zemax.com/got-a-question-7/sequential

Later in my career, I worked for a company whose principal technical strength was that they knew how to glue optics together in such a way that they NEVER moved, either thermally, or from shock. Detachment? The optic would break in an area

Toyotas DO break less. But their designs are stodgy, very slowly updated, and generally draw premium prices. So customers keep flashier makes in business.

Heh, heh. They ignored my input and kept shipping. Then the customers began calling… Meanwhile our major competitor cleverly placed their rotating element in such a position that the beam retraced itself through the rotating element, thereb

There’s an enormous opportunity and need for adverse products to quickly detect LLM-produced content. We also need labeling, like the nutritional information on food packages.

One early Saturday morning around 1975 I walked into the Berkeley Physics Dept. student machine shop. A bunch of nerds were clustered around a big lathe that no one ever used because it had so much backlash. Chucked in the lathe was a vacuu

Most of us can learn to play chess in 10 hours. Few can become grandmasters. Most Hacker News readers have gotten through calculus. Few have gotten through the mathemamatics needed to study elementary particle physics, let alone abstract ma

They didn’t talk about matrix exponentiation, which appears all over system and control theory and quantum mechanics. I wrote them about this just now.

I had serious withdrawal symptoms 24 hours after medicating myself with controlled doses of hydromorphone after surgery. It’s always been remarkable to me how many people confidently assert I wasn’t addicted.

Exactly. Toastmasters is good for bright working class people with limited education who find themselves in competition with college graduates for advancement in corporate settings. This is a very common situation in the U.S. where corpor

Yes this is taught. Salespeople are taught that if the sales prospect makes a pejorative or other remark that absolutely must be be overcome to close a sale, they should steeple their hands, engage the prospect, but never overtly disagree o

Appearance and posing is critical in projecting dominance. Forty years ago, this was drilled into the young product managers at Spectra-Physics, and really, corporate uniforms have not changed much. This was so important to Donald Trump tha

Of extremely more interest than learning rate is learning ceiling. They are not uncorrelated. But the integral of the derivative is vastly more important than the derivative itself.

Screenshot->crop->Apple Notes is very standard for me. I try to remember to select and copy some appropriate text from the page to act as title text. Copying the url into the note completes it.

No, it isn’t. The Florida Democratic Party is the equivalent of a 2-15 team in American football. Zero talent, zero bench, zero promising newcomers, to first order.

I wouldn’t approach it in terms of “enforcing antitrust laws.” It’s very hard to win those cases. What I would do is limit the cash that public companies can retain. This has the effect of distributing capital to new ventures and competito

You know, with Musk’s problems in getting starship off the ground, it’s useful to recall the ultra simple design choices in the Saturn 5. But this?
