The Left Hand of Darkness, by Ursula K. Le Guin

After reading the epic Foundation series of novels by Asimov, I was in the mood for a change of pace in science fiction.  I turned to another brilliant author, Ursula K. Le Guin, and her classic 1969 novel The Left Hand of Darkness.


I vaguely remember being told about this novel when I was in college, though I didn’t read it then. At the time, the description that I was given was more or less “a book entirely about linguistic, social and cultural details.”  This description isn’t completely inaccurate, but The Left Hand of Darkness is so much more — it is a fascinating study of a culture that is completely alien to our own, thanks to one, single, fundamental, biological difference in its humans.

Pepper’s last optical illusion: metempsychosis

A month ago, I shared the lengthy, odd and sometimes dramatic history of the illusion commonly known as “Pepper’s ghost,” which I believe is more properly called the “Pepper-Dircks ghost.”  In researching this post, I uncovered a wealth of fascinating information and trivia related to Pepper, Dircks, and their work, which continues to serve as fodder for posts.

For instance: “the ghost” is not the only optical illusion that John Henry Pepper (1821-1900) developed! Much later in his life, when the ghost had lost some of its novelty, Pepper worked on and patented a clever new illusion, which he called “metempsychosis.”

So what is metempsychosis?  In this post, we take a look!

Foundation’s Edge, Foundation and Earth, by Isaac Asimov

Been rather preoccupied recently with life, but I finally have a moment to catch up on a bit of my book blogging, including discussing the “final” two books of Asimov’s classic Foundation series, namely, Foundation’s Edge (1982) and Foundation and Earth (1986).  I have previously written about the first book Foundation as well as the complete trilogy of books, finished in 1953.


I wrote “final” in quote above because, although these are the final two books chronologically in the fictional Foundation universe, they are not the last two books that Asimov would write.  Two prequels to the original novel would follow: Prelude to Foundation (1988) and Forward the Foundation (1993).  But Edge and Earth would be the last novels that would advance the history of the Foundation and hint at its ultimate fate.

Twitter Weird Science Facts: Full Year and Final Volume!

This is it — the last regular installment of my Twitter weird science facts! I’ve done a full year of weirdscifacts, averaging one fact per day for the entire year (though I’ve had to play catch up on missed days quite often).  It’s quite a lot of work to find and post reliable facts every day, even with the amount I’ve got backed up, so I won’t be continuing the series at this time.  You can always read the whole series of this year, and past years, by clicking this link.

Read below to learn about the long history of dropping balls to signify time, as in this 19th century image!

ENGLAND - MAY 28:  Engraving taken from the ?Illustrated London News?. The first national electronic time service was introduced by Sir George Bidell Airy (1801-1892), Astronomer Royal and director of the Royal Greenwich Observatory from 1835 to 1881. A master clock, verified each day by stellar observation, sent electric impulses to clocks throughout the country via the growing network of telegraph wires providing for public and railway use. The time ball at the Strand received the impulses hourly from the Central Telegraphy Station of the Electric Telegraph Company.  (Photo by SSPL/Getty Images)

19th century optics FAILs

My recent post on the Pepper-Dircks ghost didn’t include even close to all of the interesting tidbits it could have!  There are so many things to learn from the story of the ghost, including some lessons about optics.

For example: in my post, I included two illustrations of the illusion at work from sources of that era.  One came from the 1868 book The World of Wonders

… and the other came from an 1877 edition of Harper’s Magazine.

The images are so similar that I’m guessing the latter was based off of the former.  However, both of them are wrong!  They incorrectly show how the ghost works and how it would appear in the configuration as shown.

So what’s the problem? If you like, take a moment to look at the image or images above and see if you can work it out for yourself!  Then read on below…

Isaac Asimov’s Foundation Trilogy

I’ve recently been trying to become more acquainted with science fiction as a genre, as most of my life I’ve been focused primarily on horror fiction.  A natural and obvious place to place some emphasis is on classic works from the golden age of science fiction, and a natural and obvious place to start there is with the work of Isaac Asimov.  A few weeks ago, I read Asimov’s Foundation (1951), and blogged my thoughts about it.

Asimov has written seven books set in the Foundation setting; I figured that I would be content reading the first one, to get a feel for it, and then move on to other authors and other series…

… and, as of today, I’ve started reading the fifth of the Foundation novels.

As the first three books, Foundation (1951), Foundation and Empire (1952), and Second Foundation (1953), form the original trilogy, and I thought it would be worthwhile to blog my thoughts on the trilogy as a whole.


The Foundation trilogy tells an epic, galaxy-spanning story over the course of some 400 years, telling the early history of what is known simply as, well, the Foundation.  Some 12,000 years into the existence of a powerful galactic Empire, a mathematician named Hari Seldon predicts, using a new and advanced mathematical science known as psychohistory, the collapse of the Empire within 300 years and a galaxy-wide Dark Age to follow lasting some 30,000 years.  The collapse of the Empire is inevitable — the actions of quintillions of humans in the Empire possess a momentum that cannot be overturned in time to avoid disaster.
