Rovelli: Reality Lessons

Sunday I breezed through Seven Brief Lessons On Physics (2014), by Carlo Rovelli. It’s a quick read of only 96 pages that still manages to touch on some of the key aspects of physics.

His much longer book, Reality Is Not What It Seems: The Journey to Quantum Gravity (2014), covers the same territory in greater detail (and greater length: 288 pages). After I finished what amounted to an appetizer, I tucked into the main course. I’m about 30% through it and am enjoying it quite a bit more than I have his work so far.

Both books, but especially the longer one, explore the theory of Loop Quantum Gravity (LQG), of which Rovelli is a co-founder.

Old School Viral

Remember when “going viral” didn’t mean hospitalization and possible death? (Obviously if we go back even further to the original meaning, it did.) I had an old post go briefly and mildly viral last week. Big traffic spike with a very rapid tail-off. Most bemusing.

I’ll tell you about that, and about a spike on another post, this one weirdly seasonal — huge spike ever September for three years now. I have no idea what’s going on there. Most puzzling.

There is also a book about the friendship and conflict between Albert Einstein and Erwin Schrödinger that I thoroughly enjoyed despite it not being my typical sort of reading (I’ve never gone in much for either history or biography).

A Better Debate

Our next VP? I sure hope so!

I thought Kamala Harris did very well last night and that the debate was a welcome return to almost normal politics (to the extent politics can ever be said to be “normal”).

In particular, she showed more signs of life than Joe Biden did, and she showed some appropriate emotions towards her opponent.

Karma

The thing about facts is that they always win in the end.

(Must resist urge to wallow in schadenfreude…)


More Multiplying

At the beginning of the month I posted about a neat Japanese visual method for multiplying smallish numbers. Besides its sheer visual attractiveness, it’s interesting in allowing one to multiply numbers without reference to multiplication tables (which, let’s face it, typically require rote memorization).

As I mentioned last time, my interest in multiplication is linked to my interest in generating Mandelbrot plots, which is a multiplication-intensive process. But for those learning math, digging into basic multiplication has some instructive value.

With that in mind, here are some other multiplication tricks.

Agatha Christie

Shakespeare talked about the ages of man, and it’s well known that age seems to revert us to our youth. The last handful of years that’s been true for me with regard to mystery authors. For the first time in many decades I’m reading (or rather re-reading) Dorothy L. Sayers (Lord Peter Wimsey), Rex Stout (Nero Wolfe), and others from my past.

This month I’ve been enjoying Agatha Christie and her Hercule Poirot novels. I got into them after finishing a collection of 51 short stories starring her famous Belgian detective (with his “egg-shaped head” and giant mustaches). Reading those put me in the mood to revisit the novels.

And I must say I’ve been thoroughly enjoying them!

Sci-Fi September

The post’s title is something of a misnomer (as there has been little, if any, science fiction for me this month), but I have an absolute and abiding affection for alliteration. (Which explains Sci-Fi Saturday, Mystery Monday, TV Tuesday, and Wednesday Wow.) I couldn’t resist the title once it popped into my mind.

Seriously, about the only SF in September was opening and shelving a box of books. But since October will be so political, I want to clear some notes. Call it a Fall Clearance — Low, Low Prices!Everything Must Go!

Some rake their lawn of fallen leaves. For me, it’s that pile of notes that I seem unable to ever fully vanquish.

Got the Shot

Sort of. It’s not quite the shot I’d hoped for, but it’s close-ish:

There actually is a cloud bank on the eastern horizon, so the Sun wasn’t too visible as it rose, but once it got a bit above the horizon, it was. And, a day later, it’s moved a bit south, too.

Best Laid Plans

One of my favorite lines of poetry comes from the great Robert Burns poem, “To A Mouse, On Turning Her Up In Her Nest With The Plough” (not to be confused with his similarly titled “To A Louse (On Seeing One On A Lady’s Bonnet, At Church)”).

The line in question is, “The best-laid schemes o’ mice an’ men; Gang aft agley,” (go often astray), and — as you see — it applied to my plan to capture the last sunrise of summer this morning.

Monday Miscellany #4

Ralph Emerson famously said, “A foolish consistency is the hobgoblin of little minds,” but I also like what Wilde Oscar said: “Consistency is the last refuge of the unimaginative.” The last two words in both sentences signify something important. Consistency is the enemy of creativity, art, and philosophy, although it’s generally welcomed in other places (one’s airline pilot, surgeon, or government, for instance).

Which is all by way of excusing the dreadful consistency of this so-called Monday Miscellany series. Episodes in 2012, 2014, and then not again until 2020, is barely a series. Another one so soon is definitely suspect.

Chalk it up to “creativity, art, and philosophy.”
