Well, Ive been so very negligent in my dedication to this blog over the last few years, and I need to do some catch up. I've read quite a few books over the last few years; so many in fact, that I need to group them just to cover them all here in a short time. So, I'll start with some Science and Physics tomes, plus a really odd "classic"...
Six Easy Pieces
An interesting read from one of my fave physicists, Richard Feynman. This is a brief (140 pages)
summary of six basic themes from the Feynman Lectures on Physics (1200 larger pages) - Atoms, basic Physics, Physics vs other sciences, Conservation of energy, Gravitation, and Quantum mechanics.
Concepts are covered in some detail, with diagrams, but very little mathematics.
Not for the faint of heart, but suitable for the interested and motivated layman.

Astrophysics for People in a Hurry
A nice quick read on modern astrophysics, by Neil deGrasse Tyson. Is that actually possible? Well, Tyson managed it, and kudos to him for doing this - he’s truly the modern-day Carl Sagan - a qualified person able and willing to educate the masses (or those interested) in complex, larger-than-life (literally) concepts. I liked Tyson right from the start - in his Cosmos redux (re-do of Sagan’s 1980s TV series of the same name), he tells us that “for all we know about dark matter and dark energy, we might as well call them Fred and Barney.” I loved that. It has always bugged me that so many of today’s scientists talk about cutting-edge stuff like that as if it were a done deal - proven 100% and we’re moving on. When the truth is that we NEED those things to be true, or else our understanding is at least a little bit wrong. We THINK they’re real, and we NEED them to be real, but that doesn't mean that they ARE real. Anyway, Tyson gives the best, and most clear description of concepts like these, and the reader will come away much richer for reading it.
Ok, now the bad part. While he does maintain that we don’t know enough about them, he takes his rhetoric too far in insisting that in fact dark matter is real. He says that gravitation probably doesn’t behave differently over great distances, even though it behaves differently over infinitesimally small distances (how can you just say that as if it’s a given?). Second, he says that dark matter and aether are not the same (in that we invented them out of necessity). Why? - because dark matter solves a problem with understanding observations, while aether solved a lack of understanding of the nature of electromagnetic wave propagation. Come on Neil! We invented both of them!! One was disproven, the other has yet to be proven/disproven. (And btw, you can’t look at a problem, invent something to help explain it, and then turn around and say that the solved problem proves the invention!)
And disappointingly, he takes a few jabs at religion. Honestly, I don’t care about an astrophysicist’s views on religion any more than I care about their views of what’s better- the 1969 Mustang vs the 1967 Camaro- or the taste of cheddar cheese vs peanut butter.
Those things aside, I think this is a great book.

The End of Everything
(by Katie Mack)
Some things about physics bore me (like dark matter and dark energy being talked about like they’re 100% real), other things (like the Big Bang, how, why, evidence) excite me. This book covers some topics in cosmology that are cutting edge - inflation and expansion (how does it work??), whether the universe is open or closed (not all the evidence is 100% convincing), and more.
Starts off with the author pooping on the religious aspects of “the end” - I get it, atheists hate religion. I get it, I said. But come on. Talk about what you’re qualified to talk about, and please just stick to that. PLEASE. Another thing that has always bugged me is scientists talking about dark matter and dark energy as if they were 100% real, and there is no doubt about it; they’re there, and we’ve proved it beyond any doubt. Please. She talked about the “discovery of dark energy” - sigh. But to be fair, later in the book she comes clean, saying “dark matter, the cosmological constant (dark energy) and inflation are completely mysterious…” and even better, “inflation (was) designed to solve … cosmological problems” - okay; that’s better. I really, really prefer honesty to arrogant hey-I’m-a-scientist assertions…
Anyway, other than that, interesting topics; among them:
Big Crunch: The closed universe - my fave even tho every physicist on the planet disagrees - not enough matter (apparently) to bring it all back. (And you’d need all the radiation back too, so all of space would somehow have to get sucked back. Hmmmm…)
Heat Death: Open universe. In this version, eventual evaporation of all matter in the universe due to entropy and heat radiation, and the universe achieves equilibrium at a very low temperature after a very long time. I don’t like it. Mostly because I think Hawking is wrong; I don’t think black holes can just go away. Either way, “Heat Death” feels real enough, even though I don’t like it.
Big Rip: If the equation of state variable of the universe (w) is -1, dark energy is the cosmological constant (apparently). If w is a variable, and it changes to less than -1, expansion goes out of control, and everything is eventually ripped apart. Doesn’t seem likely to me…
Vacuum Decay: The Higgs boson is also a field (just like light is both a wave and a particle), and if that field changes due to some powerful event, the Higgs boson could find a lower state of rest, causing particle bonds to be impossible (no atoms, molecules; just loose particles). Also doesn’t seem likely to me, but not as bad as the rip…
Bounce: The expanding existence of our universe bounces off the expanding existence of another universe, ending both in a minor multiverse incident. Yeah, no.
All in all, this book kept my attention from start to finish (with some bumps). Mostly, it made me think a lot about all these scenarios, and a lot more concepts beyond them. And I guess that means it was a pretty darn good book.

The Prince
(by Niccolo Machiavelli)
The author of the concept of “the end justifies the means” - Machiavelli tells us how a “prince” or the leader of a state can retain his place and govern well by any means. Modern thinking says that no, he never says that; well, that’s wrong. He pretty much does.
He goes out of his way to say that a prince must destroy the family of a rival from whom he has seized a state - I think that means kill the whole family, men, women and children. He also says people should be either pampered or crushed, that a ruler should not be generous, should not obsess about keeping his word, should be fine with using cruelty, and so on.
It is true that he writes about how a ruler needs to behave in order to ensure stable government. No doubt this arises from the precarious state of Italy during his time (late 1400s, early 1500s); in fact this whole book could be seen as his recommendations for a leader - any leader to unite Italy, as he discusses in the final chapter. For me, I was just interested in how he positioned his arguments; interesting enough, but not a terribly great read…
(Just have to say here, that the painting reminds me of my old buddy Pat Lakanen...)
