What is quantum entanglement? Part 2: Randomness and measurement

This is part 2 in a lengthy series of posts attempting to explain the idea of quantum entanglement to a non-physics audience.  Part 1 can be read here.

So, by the mid 1920s, physicists had made significant progress in developing the new quantum theory.  It had been shown that light and matter each possess a dual nature as waves and particles, and Schrödinger had derived a mathematical equation that accurately described how the wave part of matter evolves in space and...

What is Quantum Entanglement? Part 1: Waves and particles

If you follow science, or science fiction, to any degree, great or small, you’ve probably heard the term “quantum entanglement” before.  You may also have heard it referred to as “spooky action at a distance,” and understand that it somehow involves a weird connection between separated quantum particles that can “communicate,” in a sense, over long distances instantaneously.  You may have read that quantum entanglement...

The Southern Reach trilogy, by Jeff VanderMeer

I’m not entirely sure why it took me three years to read Jeff VanderMeer’s Southern Reach trilogy.  One of his earlier novels, Finch, is on a very short list of “best books I’ve ever read.”  I suspect that I simply read the name “Southern Reach” and it somehow evoked images of the Southern United States in a weird way that didn’t appeal to me, and I just never got around to looking at the books.  Until, that is, I read the...

Chills, by Mary SanGiovanni

I’ve been in a bit of a funk the past few weeks and haven’t been reading much.  What I needed to get myself back on track was a nice solid bit of horror fiction, and fortunately I had on hand the most recent novel by Mary SanGiovanni, Chills.

As is made clear from the cover image and the title, Chills centers on a danger that originates in the coldest weather.  A team of detectives and investigators race, in the midst of a blizzard, to solve a series of grisly murders and...

Optics basics: reflection

It’s been some 5 years since I wrote my last “Optics basics” post!  The goal of that series of posts was to introduce some of the most fundamental concepts in optics in a non-technical way, in part so I wouldn’t have to constantly reexplain them in more advanced posts.

I’ve covered most of the topics that I would truly call “basic” — hence the long time since the last post — but I realized that I missed one concept that...

When spiders get together and make a huge web, it’s either a delight or a terror, depending on how you feel about spiders!


Bizarre bivalve: first living giant shipworm discovered in Philippines

Bizarre bivalve: first living giant shipworm discovered in Philippines:

Here is a description of a freaky marine creature for you for the day: 

About three feet long and glistening black with a pink, fleshy appendage, it looks like the entrails of an alien from a bad horror film. In fact, it is a giant shipworm.

Discovered in the mud of a shallow lagoon in the Philippines, a living creature of the species has never been described before – even though its existence has been known...

Analysis | Spiders could theoretically eat every human on Earth in one year

Analysis | Spiders could theoretically eat every human on Earth in one year:

It’s been a while since I posted, but I thought I’d share this moderately creepy factoid via the Washington Post: 

Or, for a slightly more disturbing comparison: The total biomass of all adult humans on Earth is estimated to be 287 million tons. Even if you tack on another 70 million-ish tons to account for the weight of kids, it’s still not equal to the total amount of food eaten by spiders in a given...

The geometry of weird-shaped dice

I’ve been enjoying a bit of reminiscing about my childhood lately, hunting down old copies of role-playing games I enjoyed in my youth as well as exploring newer games that have come out since then.  One thing that has changed dramatically since my gaming days is the proliferation of types of dice.  Most human beings never go beyond ordinary 6-sided dice, which we in the gaming world call a “d6.” Classic Dungeons & Dragons players, however, are...

Once again, it turns out reality is much more freaky than the imagination of the most twisted horror writers.
