Learn about Multiverses
 

Bob Wickman says we live in a universe of indescribable size. Yet the mathematics don’t rule out yet other universes, the “Multiverse,” and in some cases require them. Unlike other aspects of cosmology, the several possible forms of other universes that we’ll discuss are just speculative theory – they are unproven.

We will meet Monday, May 19, 2025 @ 1:00 PM at the Everglades Rec Center.

Quantum physics - I wish I had the mental capacity to understand it better. Every year I try to read Stephen Hawking's "A Brief History of Time" and I can't ever get past the first chapter. I keep trying though! I've also read every Robert Heinlein book ever written including his short stories and the book his wife put together from his letters to his publisher, after he died.

Impressive. Yea, A Brief History needs just a bit more dumbing down for me.

Come on down
 

Often, the presenters will let us upload a copy of their presentation to our past presentation archives site. Then you can review (study) it at a later date.

I'm a voracious reader. I read only sci-fi/fantasy for around 20 years. Plus I learned to code, which got me interested in math for the first time in my life, and that got me interested in quantum physics. I still can't "get it" yet. One of these days I will.

Great lectures
 

Google “ The Feynman Lectures on Physics”. He does a great job explaining quantum mechanics in

He does, as far as he could. But he passed in 1988, and A LOT has happened since then. He only knew of three quarks: up, down and strange. The Higgs boson wasn't discovered until 2013, although Peter Higgs et al put forth the theory in 1964. The LNC at CERN wasn't quite on the drawing board. The mechanism by which the weak force mediated by the W and Z bosons could change the flavor of quarks was unknown. Nonetheless, it is a pretty good starting point

Never met a quark that was nice to a boson. Why is that?

They're very nice to each other. How else could a bottom quark change to an up quark and an electron neutrino???

I was a very good bricklayer and general builder, definitely no lower or even upper quarks in my work!

Well you know what they say. You can quark a neutrino some of the time but sometimes the quarks _____ and the results are not pretty.

There are no lower or upper quarks anywhere. Just up. down, strange, charm, top and bottom. (I didn't name them)

But quarks get along well with each other, after all mesons consist of a quark and an antiquark. I don't understand why they don't annihilate each other, but there's a lot in the quantum world I don't understand.
