Catching "The Wave": still relevant

Aug 13 2009 Published by under ... the Hell?, [Politics], Entertainment

Watching crowds of lunatic extremists attempting to shut down any reasonable debate about healthcare by shouting down politicians at town halls and even bringing firearms to protests is reminiscent of the scare tactics that brownshirts used to secure power in pre-WWII Germany, a point that has been made by at least one observer.

It's worth pointing out that strong-arm and intimidation tactics, though often viewed as acceptable in an "end justifies the means" way,  tend to spiral out of control because of their very nature.  I'm reminded of an old made-for-TV movie, The Wave, about a high school teacher who starts a "youth movement" as a lesson which spirals quickly out of control.  The entire movie can be viewed on YouTube, in two twenty-something minute parts:

The movie, and its novelization, are based on a real-life incident which occurred in California in the 1960s.

Nice interviews with Richard Garriot and Lyn Evans on Vice/VBS.tv

Aug 12 2009 Published by under Entertainment, role-playing games

A few months ago, I got a nice email from the folks at Vice Magazine/VBS.tv pointing me to a video interview they did with Richard Garriot (aka "Lord British"), the fabulously wealthy fantasy computer-gaming guru responsible for the Ultima series of games.

I was distracted by other things at the time (did I mention I'm trying to get my tenure package together and finish a book?), but I was reminded of Garriot by another email advertising a written interview with Lyn Evans, one of the project managers at CERN.

The Evans interview (which can be read here) is a nice discussion of the basic goals of the collider project and last year's startup problems.

The 20-minute Garriot interview (which can be viewed here) is absolutely fantastic!  Not only does he share the story of his development of his line of fantasy games and his experiences in space, but he gives a tour of his really cool mansion.  This mansion includes a dungeon, secret passageways, pre-first-editions of the Lord of the Rings novels, and cool science toys like an observatory and ferrofluid manipulator. The interview contains lots of fascinating tidbits about Garriot's life and views.

(We need more wealthy people like Garriot, who put their wealth towards fun and creative projects!)

Invisibility physics: "Reflectionless" objects make an appearance

Aug 10 2009 Published by under Invisibility

(This is a continuation of my "history of invisibility physics" series of posts.  The earlier posts are: Part I, Part II, Part III.)

Up through the late 1940s, it seems that the only type of invisibility that authors were considering were "radiationless orbits": motions of charged particles of extended size which in principle could accelerate without emitting radiation.  These are not invisible objects per se, but rather objects that should produce radiation according to conventional wisdom but in fact do not.

A truly invisible object would be one which does not scatter any radiation incident upon it; that is, light which shines on the object is not reflected or absorbed, but instead is transmitted in such a way that it appears to the outside observer as if there were no object present.  But are such invisible objects even possible?

In 1956, a paper appeared in the Journal of Applied Physics which provided at least a partial answer to this question.  In their article, "Reflectionless transmission through dielectrics and scattering potentials," Irvin Kay and Harry Moses demonstrated theoretically that one could construct stratified media that perfectly transmit waves of a given frequency, regardless of the direction of incidence of the illuminating wave.  Light shining on their theoretical media would be completely transmitted, with no reflected light!

ResearchBlogging Editor's selections: False primates, hot jupiters, comet controversies and clever corvids

Aug 10 2009 Published by under General science, Science news

(Cross-posted at ResearchBlogging.org News.)

  • Suminia getmanov: A false primate: Over the past few months, you have probably heard a lot about "Ida", a magnificently-preserved fossil of a 47-million year old primate.  You may not have heard about the fossils of 260-million year old primate-like suminia, which is some 200 million years older than the first primates.  A Primate of Modern Aspect discusses what is known about these creatures, and the implications for evolution.
  • Cthonian Ftargn!: Over at Supernova Condensate, Invader Xan tells us about the recently proposed and observed class of "hot Jupiter"-like planets, known as "Cthonian planets".
  • Was there a comet impact in AD 536? Maybe:  In AD 536, some sort of catastrophic event caused widespread famine and a drop in global temperatures, confirmed by tree ring data and what little historical accounts exist.  The most obvious suspect is a massive volcanic eruption, but other evidence suggests that a comet impact may be the culprit.  Emma at We are all in the gutter describes the controversy and the evidence on each side.
  • Those clever corvids:  Confirming my suspicion that birds are planning to take over the world, Mo at Neurophilosophy discusses the astonishing tool use of rooks, a relative of the crow.  The videos are not to be missed!

Animals keep getting smarter...

Aug 07 2009 Published by under Animals

I'm totally fascinated by stories and research on animal intelligence.  The closer researchers look at animal behavior, the more they're surprised by unexpected cognitive abilities.

A wonderful case in point: researchers have recently shown that rooks (a relative of crows) can solve problems on a level that is nothing short of astonishing (h/t my postdoc advisor, from BBC News):

One of Aesop's fables may have been based on fact, scientists report.

In the tale, written more than 2,000 years ago, a crow uses stones to raise the water level in a pitcher so it can reach the liquid to quench its thirst.

Now a study published in Current Biology reveals that rooks, a relative of crows, do just the same when presented with a similar situation.

The team says the study shows rooks are innovative tool-users, even though they do not use tools in the wild.

Another paper, published in the journal Plos One, shows that New Caledonian crows - which like rooks, are a member of the corvid group, along with ravens, jackdaws, magpies and jays - can use three tools in succession to reach a treat.

There are accompanying videos on the BBC site, which are quite spectacular.  Stories of ravens solving problems and using tools are not new, but this story is quite amazing because of the indirect nature of the solution and the connections which the rook must make to arrive at that solution.

The cognitive abilities of birds are quite frightening!  The wife and I are planning ahead and trying to placate them with lots of bird feeders in the backyard on the off chance they decide to take over.

Also via my postdoc advisor is this charming little anecdote from Holland.  In eastern Holland is a fascinating nature park called Apenheul ("ape hill"), in which the smaller primates are allowed to roam free and interact with the visitors1.  The article from Het Parool is in Dutch, so I will quote my former advisor's email:

Among the different brands of monkeys that are allowed to roam free there are so-called berber monkeys. The gorillas of course aren't. But they get fed at certain hours, and one of those berbers likes to watch that and simply takes a seat among the other spectators. After the feeding show he or she simply heads back to his part of the zoo.

The picture from Het Parool is rather priceless:

1 I had pictures from Apenheul, but I foolishly checked my camera on the return flight from The Netherlands and had my memory card swiped from it.

Marie Corelli's Ziska

Aug 06 2009 Published by under Horror

(I've had a backlog of fiction I've wanted to blog about, and a lack of energy for physics blogging thanks to heavy work on my book.  I'll get back to science-y posts in a few days.)

1897 was a very good year for Gothic fiction!  That year saw the publication of Bram Stoker's Dracula and Richard Marsh's wildly successful The Beetle, which I've blogged about previously.  Even more works were published that year, however, which thankfully have been resurrected in recent months by the good folks at Valancourt Books.  A couple of days ago, I finished their edition of Marie Corelli's Ziska: The Problem of a Wicked Soul:

ziska

The novel tells a story of supernatural romance and revenge, set in Cairo and set against the backdrop of ancient Egypt.  I found it an very enjoyable and atmospheric read and am glad it has been rediscovered after so many years of neglect.

The Time Axis by Henry Kuttner

Aug 03 2009 Published by under Adventure fiction, Mathematics, Weird fiction

The more I read of Henry Kuttner, the more ashamed I am that I didn't read all of his works long ago!  Henry Kuttner (1915-1958) was a versatile writer of pretty much every genre of weird fiction imaginable: science fiction, horror, fantasy, adventure, and things that defy ready classification.  His is undeniably one of the most influential science fiction writers of the early 20th century, and many of his short stories are beautiful and classic.

I've been using this blog as an excuse to read more of Kuttner's work, though I don't really need one!  I've previously written about his foray into sword-and-sorcery fiction, in his Elak of Atlantis stories, and his exploration of adventure stories, with Thunder Jim Wade.  All of these are short stories, however, so I finally got around to reading one of his novel-length works, The Time Axis (1948):

thetimeaxis

(picture of an early edition via Fantastic Fiction.)  The book is currently available in an excellent quality albeit rather plain edition by Wildside Press, and can also be read online.

It's great!  Like a lot of Kuttner's work, it manages to blend a pulp adventure tale together seamlessly with a science fiction story, and gives the reader a sense of awe and wonder that is altogether rare in fiction.

Biltmore Estate... and Rick Springfield!

Aug 03 2009 Published by under Entertainment, Travel

This weekend, the wife and I took a trip up to Asheville, NC, to see the historic Biltmore Estate... and see a Rick Springfield concert! The trip was an absolute blast, and I thought I'd share some pictures of the Estate grounds, as well as of the concert itself.

Biltmore consists of a massive home of some 250 rooms and grounds of some 8,000 acres , and it is the largest privately-owned residence in the country.  It was built in the 1890s for George Washington Vanderbilt, who had inherited a fortune from his railroad tycoon father and grandfather.  Vanderbilt was a celebrity of his time, and built the home in part to escape from the chaos of New York City and the attention he received there.   Vanderbilt died in 1914, leaving his wife Edith the master of the estate.  In 1930, at the height of the Great Depression, daughter Cornelia opened the estate to the public so that the tourist draw could increase the area's local revenue.  The house remains in family hands, and is now a wonderful tourist attraction.
