Just dusted off my old maths books

To me that happened when I started at the university. I got slapped straight in the face with a frying pan. That was my punishment for having gone through my school years without needing put in any effort at all.

I know exactly what that means... :doh: :sigh: That's why I wrote down my thoughts when I was understanding things, because I knew that my memory won't keep it for the future. But thanks to my notes I am able to get through most of the stuff way easier than it would have been without them.

For 20 years I've been saying "I'm going to pull out my old university maths books and relearn what I did during those painful 4 years". For years and years I kept procrastinating until this weekend. I'm starting with the simplest and my favourite, [Calculus by Michael Spivak](https://www.goodreads.com/en/book/show/328645.Calculus) (the classic!) and, well... I don't feel as smart as I used to. I seriously thought I'd pick up the book (and this is an entry level to Calculus) and breeze through it in an hour or so, nodding wisely, reminiscing over proofs by induction, mucking around with limits, breezily finding the derivative of tan(Θ) from first principles, and then crack a beer and feel that I still had it. No, that didn't happen. I got to chapter 2 and proved d/dx(xn) = n.x(xn-1) and then had to have beer and a lie down. Anyone else opened that box past glories and been slapped with the reality that yes, that stuff was and still is hard work?

You're obviously smarter than I am.

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.

Easier than without them doesn't necessarily means easier than you ;)

One man's opinion: The entire problem with collegiate mathematics is contained in this one word... - Trigonometry. 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.
