Optics basics: Young’s double slit experiment

As I’ve so far been restricting my ‘optics basics’ posts to discussions of fundamental concepts related to optics, it might seem strange at first glance to dedicate a post to a single optical experiment.  What will hopefully become clear, however, is that Young’s double slit experiment is connected to so many basic concepts in optical physics  (and still provides surprising new results to this day) that one post is hardly enough to describe all the interesting insights that can be gained by studying the experiment and its implications.

OpenLab 2009 submissions open…

I keep forgetting to note this, but submissions for The Open Laboratory 2009 are now being accepted and can be nominated at this link:

openlab-logo1

The Open Laboratory is a printed collection of the ‘best’ science blog writing of the year, and contains a lot of great entries.  Think about nominating your favorite scienceblog posts for 2009; nominations are accepted through December, I believe.  This year should be particularly excellent because it is being guest edited by the excellent blogger (and cool person) Scicurious!

Of course, if I have written/write  anything you’ve thought particularly compelling in 2009, feel free to nominate it!  I would consider nominating some of my own posts, but I’m still feeling the shame of not making the cut for the 2008 edition… 😦

P.S.  It is also interesting to note that OpenLab has inspired an anthology of a different sort: the best blog writing about roleplaying games, Open Game Table! Considering I have a history in both science and RPGs, I find the connection oddly appropriate…

A miscellany of science-related stories

I’ve been stocking up on a collection of fascinating science stories which I couldn’t think of enough to comment on in a blog post.  I’ve finally hit critical mass, though, and thought I’d dump them all at once:

  • Four Spanish high school students, supervised by their science teacher, strapped a digital camera to a weather balloon and sent it up 20 miles to take pictures and atmospheric readings.  The pictures are simply wonderful.
  • The recession has hit science and scientists just as hard as everyone else, but there’s no excuse for this: a well-known paleontologist will plead guilty to stealing a fossil find from federal lands with intention to sell it.  Earlier in the month, he had already plead guilty to stealing fossils from private lands.
  • A reminder of why science is important and superstition is dangerous and counterproductive: the skeletal remains of a 16th century victim of the plague, and suspected vampire,  were uncovered in Venice.  The body was buried with a brick wedged in its mouth, which was done to corpses which were suspected to be vampires.  This reminds me that I’ve been doing some historical reading on witchcraft and witch trials that I have to blog about soon.
  • Yes, we need better volcano monitoring: Mount Redoubt, which has been showing signs of imminent eruption lately, had seemed to quiet down.  It is now back on “watch” status for eruption, after activity increased again.

UPDATE:  Is my timing great, or what?  Mount Redoubt started erupting Sunday night.

A. Merritt’s The Face in the Abyss

I’ve been continuing my reading of the works of A. Merritt (1884-1943), which began with his first serial novel The Moon Pool (1919), continued to his masterful The Metal Monster (1920) and most recently visited The Dwellers in the Mirage (1932).  I was originally planning to step away from Merritt for a little while, but one other volume caught my eye: Merritt’s 1923 serial novel, The Face in the Abyss:

faceintheabyss

I have to say that I really enjoyed The Face in the Abyss (to be referred to henceforth as FIA)!  Though not as brilliantly otherworldly as The Metal Monster, it tells a great adventure story filled with wonderful and haunting imagery, all set in a science fiction world of appreciable complexity.  Though the hero of the tale is still more or less a pulp-fiction stereotype, several of the other main characters have a surprising amount of complexity to them.

Terminator and Dollhouse surprised me tonight…

I just finished watching Terminator and Dollhouse and just felt compelled to write a short comment.  Both shows were really good tonight, in their own way.

Terminator resolved a number of huge plot threads and the same time it opened a number of intriguing new ones.   The coolest part, though, was that John Connor was finally given a moment to really shine and show the potential to be that “great leader of the future” he’s supposed to be.  The scene I’m talking about — and you’ll know it when you see it — completely captured my attention, and I pretty much never focus on one thing at a time.

Dollhouse was really good in a similar way.  Some big new aspects to the plot were introduced, and there were a number of really great twists that I didn’t see coming.  Perhaps best of all, I think I finally see how the show can work as a series.  As you may know, lots of people have expressed doubts that a show which focuses on a main character who is basically a blank slate can ever be compelling.  Though it is clear that the ‘heroine’ Echo is slowly retaining more of her past memories, this episode made it clear to me that the supporting characters may turn out to be the real focus of the show.  Echo serves as a mirror through which we can see reflections of what the other characters see themselves as, or what they want to see themselves as.  There’s a wonderful scene where a ‘villain’ looks sympathetic at the same time he calls the motives of the ‘hero’ into question.

I’ve been hooked on Terminator, and I’m glad to see that it has been living up to my expectations.  Dollhouse, I think, has finally snagged me.

I was going to joke and ask: is it a sweeps week?  But, it turns out, it is!

Infinite series are weird!

I’m in the mood to do something a little more ‘math-y’!  A few weeks ago, Tyler at PowerUp did a nice post about the divergence of the harmonic series, and that got me thinking about the weirdness of infinite series.  Since I’ve been working on a book chapter on infinite series anyway, as a part of my upcoming ‘math methods’ textbook, I thought I’d talk a little about infinite series and some unusual results associated with them!

M.P. Shiel’s The House of Sounds and Others

H.P. Lovecraft was not only a writer of weird fiction, but a voracious reader of the genre, as evidenced by his classic essay, Supernatural Horror in Literature.  He collected a voluminous library of weird titles, many of which have not been available for almost a century.  In recent years, Hippocampus Press has been reprinting a selection of these in a series descriptively named “Lovecraft’s Library” edited by the most awesome authority on Lovecraft, S.T. Joshi.  The first of these I read was the magnificent book by A. Merritt, The Metal Monster, and I’ve been curious to see what other members of the series are like.  The next one which intrigued me was M.P. Shiel’s The House of Sounds and Others (cover of the Hippocampus edition):

Relive the history of The Oregon Trail… the game!

I’m currently mulling over my next science blog post, which will hopefully be out soon.  In the meantime, I had to point out this wonderful discovery via StumbleUpon:  an Apple II emulator which allows one to play the classic educational game The Oregon Trail!

I remember The Oregon Trail as one of the few computer games which high school students were allowed to play in school back in my day, due to its history/geography emphasis.  The game allows the player to guide a family of settlers across the western United States circa 1848, from Missouri to Oregon’s Willamette Valley.  One must stock up on supplies and prepare for various random misfortunes which await you, from bad weather to illness to friggin’ thieves stealing all of your oxen!

Even though it is a crude game, I still found it strangely compelling.  I struggled to get my family back on the trail after we lost all our oxen, but unfortunately all succumbed to disease, in spite of my excellent ability to shoot bison.  It was difficult, dangerous, and damned frustrating to travel west back in those days, and the game does a good job of simulating that aspect…

University of Chicago undergraduates vs. Westboro Baptist!

I did my undergraduate work at the University of Chicago, and though I can vouch for the fact that we all took ourselves way too seriously in general, it turns out the kids there now are okay!  The homophobic Westboro Baptist Church clan, led by uber-homophobe Phelps, decided to stage a protest at the campus.  They were answered by the men of Alpha Delta Phi (h/t Americablog):

While I’m on the subject, Michael Moore’s take-down of WBC from his show The Awful Truth is still relevant, and a riot:

P.S. From the Hyde Park Urbanist (h/t Pharyngula), a bonus win:
