AI Thread Summary
The option to buy books through Physics Forums, which contributed a fraction of expenses to the site, is still available but has not been advertised recently. Users are experiencing issues with the links, often encountering server errors when trying to access them. Some members recall it working in the past but find it unreliable now. The original thread discussing this option is still accessible, but the functionality seems compromised. Overall, while the program exists, its effectiveness and accessibility are in question.

The links for that never work for me. I get a server not found error.
 
I want to thank those members who interacted with me a couple of years ago in two Optics Forum threads. They were @Drakkith, @hutchphd, @Gleb1964, and @KAHR-Alpha. I had something I wanted the scientific community to know and slipped a new idea in against the rules. Thank you also to @berkeman for suggesting paths to meet with academia. Anyway, I finally got a paper on the same matter as discussed in those forum threads, the fat lens model, got it peer-reviewed, and IJRAP...
About 20 years ago, in my mid-30s (and with a BA in economics and a master's in business), I started taking night classes in physics hoping to eventually earn the science degree I'd always wanted but never pursued. I found physics forums and used it to ask questions I was unable to get answered from my textbooks or class lectures. Unfortunately, work and life got in the way and I never got further the freshman courses. Well, here it is 20 years later. I'm in my mid-50s now, and in a...
