Buy-a-Book (you know you want to) Saturday

Regularly since 2010, at about this time of year, I've posted about Buy-a-Book Saturday. That's my personal variation of Small Business Saturday: a day (specifically, the second day after Thanksgiving, and one day after retail's infamous Black Friday) on which holiday shoppers are especially encouraged to patronize small businesses. The big-box stores and Internet giants will do fine this holiday season. But will your neighborhood, non-chain shops and boutiques?

Rara avis! Is that a book store? Check it out.

Why do I promote the buy-a-book variant? Because what business is smaller than the author toiling away by him- or herself? Because, as I (and many others) post from time to time, the publishing business is becoming tougher and tougher -- especially for authors. Because more than likely you're a reader, else you wouldn't have stopped by this blog.

So: I'm here to suggest you give serious consideration to books -- whether print or electronic or audio -- for some of your holiday gifting. Friends, relatives, coworkers, your kids' teachers and coaches, the local library you support ... surely there's a book that's right for each of them. And at least one book for yourself, of course ;-)

2018 best reads


Thanksgiving comes as early this year as it possibly can -- which means Black Friday and Cyber Monday do, too. It's best I get this annual feature posted comparatively early.

I continue to read a lot: as research, to stay current with the genre in which I write, and simply for enjoyment. Before the holiday shopping onslaught, I wanted to volunteer a few words about the most notable books from my reading (and sometimes re-reading) so far this year. When I mention a book, you can be certain I really enjoyed it and/or found it very useful. Life's too short to gripe about anything I didn't find notable (much less the several books I elected not to finish).
 
Presuming that you visit SF and Nonsense because you appreciate my take on science or technology or fiction, you might find, in the post that follows, books you (and like-minded friends, relatives, etc.) will also enjoy. Unless otherwise indicated, the dates shown are for original publication. Each cover shown is an Amazon link, often to newer editions than the original publication (and to Kindle editions, where available).

What's made the cut so far this year? Read on ...

Physics cornucopia (physicopia?)

You know my eclectic file of intriguing news from the world of physics, into which I dip from time to time? Well, that file (metaphorically speaking, anyway) is bulging. Which gives us this week's topic.

You know all those tidy equations we learn in physics classes? They often deal with idealized situations, like friction-less planes. The real world tends to the chaotic.(*)
(*)  To physicists and mathematicians, "chaos" has a precise meaning: dynamic, generally nonlinear, systems that are extremely sensitive to initial conditions.

Or does it? See "Is nature really chaotic and fractal, or did we just imagine it?" A key quote:

The way we perceive reality is a function of how we slice and dice the physical world.

No matter how you slice it, the power of mathematics -- an invention of the human mind, surely --  to explain physical phenomena remains amazing. From the Department of Mathematically Examined Arcana, consider this: "History's most successful mathematical prediction." (Because, I'm pretty sure, regular readers here yearn to understand the origin of the precise magnetic field of a single electron.)
