Nope - Bessel functions are still as meaningless to me now as then, as is the wave-function of a quantum particle constrained to the surface of a sphere (one of the questions in the exam for my second year quantum mechanics course - I was mentally scarred by that...).

I recently dug out my Calculus and Linear Algebra books out for my 16 year old who is just starting Calculus this semester with hopes of doing well enough to take Linear Algebra in a year. I looked over the books before I gave them to him and I realize that other than moral support I will be of no help to him in any of his future math. The difference with my experience is an additional 19 years of math memory loss. Glad to have a son who is academically much smarter than the old man, we just need to work on the common sense part of it all.

I'm afraid that with maths it really is a case of 'use it or lose it'. I'm sure if you persevere then in a few months time it will suddenly seem much easier.

Oh, yes, I have done that. i was surprised just how much I had forgotten and just how long it is taking to get partly "back into" the Maths....however I am now 72, but that should not be a real problem.
So I am very rusty in Maths and now need to keep reading for the next months to refresh. This will be necessary, since I want to read about AI/ML.

One man's opinion: The entire problem with collegiate mathematics is contained in this one word...
We don't do enough of it.
I remember my "Pre-Calculus" classs.
Six weeks of Algebra followed by five weeks of Trigonometry.
And then came calculus.
Pig Snot; Totally.
College Algebra should take about fifteen weeks
College Trigonometry should take about the same amount of time.
If the typical science curriculum did that, then Calculus would be fun, fascinating, loved, and cherished for life.
But I'm also a realist.
That will never happen; not on this planet.

Interpreting Statistics should be a mandatory course for everyone.
It's disturbing how we are so easily swayed through the presentation of stats without context, and how a little understanding would go such a long way towards proper understanding.

Estas Tonne - The Song of the Golden Dragon
Had never heard of him until today. Was going to make a wisecrack about I will never again pick up a guitar in my life, due to being unworthy, but really all I can say is Wow! How had I never heard of him before! Amazing! Hope you enjoy it as much as I did.

I saw him once live... it is way more impresive than in the video.
I just got this one recommended... a good one too (impressive what two guys are able to do):

Off topic, re: your signature:
Stating that "Freedom is the freedom to say that two plus two make five. If that is granted, all else follows" would be a lot more thought provoking. And it would say a lot more about freedom.

This is a quote from Nineteen Hundred and Eighty Four (to give it the correct title). It was Winston Smith's protest against the fact-bending practiced by the Party.
Yes, freedom includes the the right to be wrong as well as right, the right to fail as well as succeed, etc. But as Daniel Patrick Moynihan said, ‘You are entitled to your opinion. But you are not entitled to your own facts.’ That two plus two makes four is a fact.
