My public library has some shelves where latest editions are displayed.  My eyes landed on a book titled: Infinite Powers.....sub title; How calculus reveals the secrets of the universe.  The author is Steven Strogatz, an internationally acknowledged brilliant professor of Applied mathematics at Cornell university. ................hang on this is a legitimate endorsement of the author and the book.

The Author does not teach me how to do the calculus that gave me so much trouble at university.  What he does is make me understand how to think of it and to regard the methods as a simple set of perfectly apparent  realities.  This guy is really good at explaining and capturing the readers interest.  You need not be a math freak to enjoy this book.  Examples; he explains how Archimedes was able to arrive at a good estimate of the value of Pi.  Think of a pizza. Slice it into four parts and reassemble it in the form of a curvy edged rectangle. Slice it  into smaller and smaller and smaller wedges and the rectangle becomes less and less curvy on its top and bottom edges.  Yeah that'll work.  Archie was using his skull in inventive ways.

Strogatz tells how  to put a plate of grated cheese in the microwave and let it give you a near accurate estimate of the speed of light.  The author guy is full of fun stuff that can capture your attention.  The historic accounts of what those ancient thinkers did  or postulated are of much interest too.  For example he reminds us that at one period of time the space between the moon and earth were believed to be evil, rotten, filled with death, disease, poverty, and destruction while the heavenly places outside the moons orbit was pure and benevolent.  Saint Thomas Aquinas and the Catholic church were purveyors of those beliefs.

You should talk to some Southerners. Men sounds normal enough, most of the time, but we tend to add a 'y' and an extra 'a' to man. It becomes... mayan...

I wonder how they say Mayan.

Just like in the movies... Seriously though, my description wasn't perfect. I guess that if Mayan is a short 'a' the southern 'man' would be a long 'a' if that makes any sense? I'm not a linguist so I can't describe the phonetic differences accurately. :(

Honestly, most depictions of Southerners in film get it very, very wrong. There's a tendency in Hollywood to give leading characters deeper voices than you find in the wild, so to speak. Most southern accents are fairly highly pitched.

Some hill folk have a low and slow way of speaking, as a group, but down in the flats you find people who speak in the upper registers. I can usually peg people by their state and in Virginia I can usually get the region, if not the county.

Robert Deniro, George Clooney, and Nicholas Cage were absolutely AWFUL at southern accents. Comically bad to someone who knows what to listen for.

Excellent photos as usual. I cannot even guess what the blue object could be.

I'll give you a clue. It's plastic.

Oh, now I see. It's a piece of blue plastic.

So how did it get there?

Is that an insect at the top end? Perhaps it dragged the plastic fragment onto the leaf, for some reason.

I put it there. I didn't know I had until I found it.

Ha ha! Mystery solved.
