The Linkin’ Log: March 14, 2008

Just thought I’d point out a few interesting science posts around the web, for those who might not have stumbled upon them:

Blake Stacey at Science After Sunclipse is doing his best to shed readers with an excellent, but mathematical, post about the Dirac equation.  Dirac’s mixing of special relativity and quantum mechanics led to the prediction of antimatter, and also  naturally incorporated quantum-mechanical spin.

Tom at Swans on Tea points out that it is officially ‘Talk Like a Physicist Day‘.  So I ‘propagated’ to work today instead of ‘drove’, and instead of ‘eating lunch’ I’ll be ‘extracting energy from organic compounds.’

Chad Orzel at Uncertain Principles describes some recent interesting optical four-wave mixing experiments and their implications.

Over at PLEKTIX, Ben Allen gives a non-technical discussion of ‘causality’ in special relativity and, in essence, who to blame when something goes wrong!

A pair of heart-warming stories

We live in a world that’s pretty crappy sometimes, and the current world political situation just makes things look even bleaker.  It’s so nice, then, to occasionally see a few stories that can warm your heart and make you feel good inside.  In that spirit, I briefly describe a couple of happy tales that I stumbled across on the ‘tubes’ this week…

Making optical ‘black holes’ in a laboratory?

My attention was recently drawn to this article (h/t Personal Demon and StumbleUpon) in Scientific American: a group of researchers have concocted a relatively simple way to generate an ‘event horizon’ in an optical fiber, analogous to those found in black holes. This technique may make it possible to study, on a tabletop, some of the more intriguing theoretical predictions about black holes. I give a brief description of the theory and experiment below the fold, plus a few observations…

Solomon Kane and Robert E. Howard’s religious beliefs

Now that I’m thinking of Solomon Kane, I thought I’d do a brief post about the character, his adventures, and the clear influence Howard’s religious beliefs had on both.

Solomon Kane is a 16th century English Puritan, warrior and wanderer.  Stereotypically dour and fanatical, he wanders the globe, primarily traveling through Europe and Africa, in search of evil to vanquish and, in later stories, answers to his own theological unease.  Like all of Robert E. Howard’s fictional heroes, he is larger than life and almost elemental in his pursuits.

Solomon Kane movie?

I put this in the category of things I found that I wasn’t looking for: it looks like a movie based on Robert E. Howard’s Solomon Kane is slated for release sometime in 2008!  My blog title, of course, is taken from the title of one of my favorite Kane stories.  It will be interesting to see what is done with Kane in movie form, but if it’s anything like Hollywood’s various takes on Howard’s other character, Conan, I’m a little scared…

The Camera Obscura and a neat optical illusion

I thought I’d muscle in on Swans on Tea’s turf for a post and discuss an interesting optical illusion that is based just as much on optics as on the idiosyncrasies of the eye itself. While stumbling through StumbleUpon.com, I found an interesting collection of images at 2Loop.com showing ‘3D Painted Rooms’. An example of this is shown below the fold, from 2Loop…

Mary E. Wilkins-Freeman: Domestic Darkness

Our next horror master is Mary Eleanor Wilkins-Freeman (1852-1930). I think it is fair to call her a ‘minor’ horror master, simply because horror was not her primary fiction focus. An early feminist writer, she penned numerous novels and short story collections, and was the first recipient of the William Dean Howells Medal for Distinction in Fiction from the American Academy of Arts and Letters.

Her goal in writing ghost stories seems less motivated to scare than to highlight or illustrate the lives of contemporary women, but she still manages to produce a number of stories of significant power.

Slugbuggery takes a new twist…

This post is mainly for my girlfriend: today’s xkcd comic:

Point Break: Mars!

My mind works in rather silly ways sometimes. Posting about skydiving soon after posting about avalanches on Mars, I got to thinking about how cool it would be to skydive off of a Martian cliff. Then I started to wonder: could you? What would be a skydiver’s terminal velocity in freefall on Mars? Well, with a little prior knowledge and some physics, we can actually make a rough estimate of this!

Gary Gygax has died

It’s official: Gary Gygax, the co-creator of Dungeons & Dragons, has died.  (My friend PD alerted me to the rumor earlier.)

I credit D&D for much of my current science aptitude and creativity.  I was still in grade school when I took my first foray into the game, adventuring through (like so many others) The Keep on the Borderlands and In Search of the Unknown.  Playing D&D and later role-playing games taught me several important skills: I gained an aptitude in basic math and probability from the rules of the games (what are the odds I’ll be able to hit that AC -8 will o’ wisp?), and the development of adventures for my friends gave my creativity a workout.
