Post at Scientific American guest blog on invisibility!

For those wondering where my science-related posts have been these days, I have at least a partial answer: I have a guest post on the Scientific American guest blog on, “Invisibility: After several years of research, it’s just gotten weirder”!  From the introduction:

Is it possible to hide something within an invisible cloak? It has already been over four years since the first groundbreaking theoretical papers on invisible cloaking devices were published, stirring up a near frenzy in the physics and optics communities. Since then, new results have come at a rapid and genuinely surprising pace, and news articles on the recent developments have been a bit overwhelming, even for a worker in the field. In this post, I thought I’d take a look at some of the fascinating results that have been published on invisibility, giving some perspective on how far we’ve come and how far we have to go!

I try and summarize some of the more unusual theoretical results about “cloaking”, showing how far researchers’ imaginations have taken the field.   Give it a look; for those who may have arrived at this blog from the SciAm guest blog post, you can find more of my writings on invisibility in my archives.

Martin Cruz Smith’s Nightwing

It can take an author many years of writing to establish their own unique voice and style.  Their early works are often a fascinating “what if” scenario, giving a glimpse of directions a well-known novelist may have alternatively taken.  The author Martin Cruz Smith is best known for his Arkady Renko series of mystery thriller novels including Gorky Park and Red Square; before this, however, in 1977, he wrote a horror novel titled Nightwing:

A horror tale that may be crudely summarized as part of the “When animals attack” genre, its inspiration is obvious: Peter Benchley’s Jaws was released in 1974 and the blockbuster movie came out in 1975.  There was a huge demand for similarly themed stories, and I can almost imagine Martin Cruz Smith’s thought process: “You want stories about killer scary animals?  Well, suck-on-this!”

Despite its somewhat derivative nature, Nightwing is actually a nicely-crafted and quite compelling novel.  It has some genuinely creepy elements to it that transcend the otherwise rather limited genre.

With Open Lab, today was a book trifecta!

I will quickly wear out my welcome with all my self-patting-on-the-back, but I can’t help point out that today was in essence a book trifecta for me!  I already mentioned receiving the first copy of my book in my previous post.  I also received today a pdf offprint of a review article I co-wrote with Taco Visser of the Free University, Amsterdam, that has appeared in Vol. 55 of Progress in Optics!

On top of those noteworthy milestones, I was delighted to learn today that one of my blog posts, on Kerker’s invisible bodies, was selected to be included in the fifth edition of The Open Laboratory!

Three book-related achievements in one day!  I don’t think I’ll top today accomplishment-wise for some time.  To celebrate, I’m adding two new badges to my sidebar, including a link to my book and a badge indicating my status as a judge of Open Lab.  I’m starting to accumulate as many badges as a banana republic despot, but I can’t help myself.

And this will be my last self-congratulatory post for a while, at least until my next book, “Dr. SkySkull is Perfect in Every Damn Way”, is published.

First copy of Mathematical Methods for Optical Physics and Engineering arrived!

This morning was a personal milestone for me: the very first copy of my new textbook, Mathematical Methods for Optical Physics and Engineering, arrived at my office!

I’m very excited, obviously!  The book is now available through Amazon.co.uk for those in Europe; it should be available at the end of January on Amazon.com in the United States.  You can also look it up on the Cambridge website.  Now I’ve got to finish my draft of the solutions manual for it…

Weird science facts, December 29-January 4

We’ve entered a new year for my Twitter #weirdscifacts!  The previous week’s facts are below:

291. Dec 29: In the late 19th century, paleontologist O.C. Marsh speculated that stegosaurus had a second brain in its rear! This was no so crazy at the time as it perhaps appears now.  Marsh noted that stegosaurus has a large canal in the hip region of the spinal cord, and this canal was significantly larger than the animal’s brain.  Because of the smallness of dinosaur brains, it was thought that perhaps a large animal like stegosaurus needed a second brain in the rear area to control reflexes back there.  This is no longer believed, but the canal’s purpose is still unclear.

292. Dec 30: The case study of a woman who (literally) feels no fear.

293. Dec 31: Placobdelloides jaegerskioeldi, a leech that only lives in the anus of hippopotamus. (h/t @DrBondar)  This is obviously a very specialized leech.  It has not been studied very much, due to the obvious dangers of not only working with hippos, but rooting around in a hippo’s rear-end!

294. Jan 01: Start New Year’s weird facts with a bang! The Tunguska blast and other similar events.  It is really striking, and a little frightening, how frequently meteorite airbursts occur with energies in the kilotons of TNT or higher.

295. Jan 02: Physicist Roger Penrose’s geometric work influenced the art of M.C. Escher.

296. Jan 03: Vampire bats: a 40g bat can drink 20g of blood in 20 mins — and pee most weight away in 2 mins. These bats are remarkably adapted: they drink so much blood that they can’t even fly with it all, but their bodies quickly absorb the nutrients and pee out the leftover liquid.

297. Jan 04: Soldiers can collapse a bridge simply by marching across it: ex. Angers Bridge, 1850. Such bridge collapses are an example of mechanical resonance.  Bridges, buildings and other structures tend to have characteristic frequencies of vibration, and external forces that vibrate in synch can produce massive oscillations of the structure that can lead to failure.  The most famous example of this is the original Tacoma Narrows Bridge, which collapsed due to wind forces in 1940.

In the case of the Angers Bridge, the resonance was induced by soldiers marching in lockstep across it.  The disaster led to soldiers being advised to break step when crossing bridges, though evidently this rule had been implemented by much earlier military groups and later lost.

Which scientist would you most want to have a beer with?

I’m currently away from home at a meeting, so blogging is necessarily light.  I’ve been thinking lately, however, about various scientists and people of reason throughout history that I just flat out admire, and got to wondering which of them I would most like to meet in  a social setting and just sit down to chat with.  And maybe a beer.  So I thought I’d turn this post into a readership poll: which scientist(s), living or dead, would you most like to have a beer with?*  (Or wine, or dinner, if you’re not into beer!)

For me, I’ve got three perhaps unconventional types that stand out:

  1. Reginald Scot (1538-1599).  Scot was born and lived in Kent in the U.K., in a time of rampant fear and ignorance.  Witch-hunts were depressingly common, and tens of thousands were killed as witches during the era from 1480-1700.   Reginald Scot was a shining beacon of reason in this very dark time: after successfully defending and rescuing an accused witch in 1581, he set out to prove that witchcraft did not exist!  He published The Discoverie of Witchcraft in 1584, a stunningly ballsy move in an era when the existence of witches was church and government doctrine and arguments to the contrary were very nearly heresy.  He made powerful enemies in the process: James the 1st, of the King James Bible, became king of England in 1603, and was himself a fervent believer.  He wrote his own book, Daemonologie, in 1597 in large part as an answer to Scot’s.  James ordered that Scot’s book be burned, but Scot himself fortunately escaped his wrath, having died in 1599.  It would be fascinating to talk to Scot about what it was like being essentially alone in his rational beliefs.  Also, he would appreciate a good beer: his first book,A Perfect Platforme of a Hoppe-Garden (1574), led to Kent becoming the hop-producing center of England!
  2. Sophie Germain (1776-1831).  Sophie was a brilliant mathematician in an society which could not and would not allow women to be educated as men.  Born into a wealthy Parisian family, she taught herself the works of Newton and Euler (learning Latin in the process) while sheltered at home from the French Revolution.  Prohibited from attending the École Polytechnique when it reopened in 1794, she obtained the lecture notes and began submitting her homework under a male pseudonym, “M. LeBlanc”.  Her brilliance attracted the attention of the famous mathematician Lagrange, who became her mentor.  Germain went on to make significant contributions to the mathematical theory of elasticity and number theory.  The great mathematician Gauss got to know Germain as “LeBlanc” through correspondence as well, and was impressed with the “man’s” talents.  He was even more impressed and gracious when he learned her true identity when she took steps to protect him during a French invasion of Germany; you can read this correspondence in my post here.  It would be a delight to chat with Sophie about mathematics and her struggles as a woman in mathematics in that unforgiving era.
  3. Michael Faraday (1791-1867).  I’ve talked plenty on this blog about Michael Faraday, who was one of the greatest scientists of his time and one of the top experimental scientists ever!  He started life as the son of a blacksmith, and was essentially prohibited from the upper class world of scientific investigation.  While working as an apprentice bookbinder, his requests for a menial job at the Royal Society were ignored but he started his own experiments in the bookshop, eventually attracting the attention of the preeminent chemist Humphrey Davy.  From there, working as Davy’s assistant and personal valet, Faraday would go on to complete the unification of electricity and magnetism, demonstrate the relationship between magnetism and light, and make fundamental discoveries in chemistry, among others.  He was an excellent lecturer, and gave numerous Christmas presentations to students at the Royal Institution.  He was an activist who wrote letters in favor of cleaning the Thames.  He was also a visionary, making intriguing speculations on the nature of atoms and on the unification of the fundamental forces.  I can’t say how cool it would be to just get to chat with him about his views on physics, society, and the natural world in general.

That’s my dream of perfect scientific social encounters!  (Not counting my thesis advisor, who is awesome and I’ll be having dinner with in 10 minutes.)  Now it’s your turn — who would you love to grab a drink with, and why?  Let me know in the comments!

* This post was inspired by Carin Bondar’s regular interview question: If you could have 3 guests for dinner, who would they be?

Margaret Cavendish’s The Blazing World (1666)

It is somewhat fascinating to note that certain genres of fiction have their beginnings much earlier than generally appreciated.  Two years ago, I blogged about Edward Bulwer-Lytton’s unusual 1871 novel, The Coming Race, a utopian novel that counts as one of the earliest science fiction stories ever written.  In researching that post, however, I came across a proto-science fiction tale that is much older: The Blazing World, by Margaret Cavendish:

As one can see from the title page, this work is much older than The Coming Race — it was first published in 1666!  Though there wasn’t even much “science” in that era, The Blazing World is arguably one of the earliest science fiction novels ever written.

Weird science facts, December 22-December 28

With the holidays upon me, I haven’t had much time to blog, but I’ve made a special effort to keep up my Twitter #weirdscifacts!  Here are the facts from December 22 through December 28.

284. Dec 22: Botanist David Douglass died in 1834 when he fell into a pit trap in Hawaii and was crushed by a bull. Scientists lead interesting lives, and those lives often lead to just as interesting deaths.

285. Dec 23: Panda porn! I’ve known about this one for a few years!  (Though I probably shouldn’t admit that; somehow sounds really bad.)  Pandas have notoriously low libidos, making them difficult to breed.  They actually respond quite well to videos of other pandas in the act, however.

286. Dec 24: Freud diagnosed the grandniece of Napoleon with frigidity from failure to orgasm in missionary position. This one highlights yet again one of those odd connections between scientists and other historical figures, as well as Freud’s rather odd diagnoses!

287. Dec 25: Nobel scientists born on Christmas: A.O.R. Windhaus, Chem 1928, G. Herzberg, Chem 1971, E.A.F. Ruska, Phys 1986! This isn’t too unusual, statistically, but I wanted to do a Christmas fact!

288. Dec 26: The Guinea worm (very nasty!), and kudos to Jimmy Carter for eliminating it! I won’t describe the details of the Guinea worm here — the details are too nasty for casual, unprepared readers!  Suffice to say that it is a particularly icky parasite of humans that formerly infected millions of people per year.  Thanks to an effort by Carter’s foundation, the number of cases were reduced to the thousands this year.

289. Dec 27: Timothy the tortoise, who lived an estimated 165 years (1839-2004)! This tortoise, which died only very recently, was already old by the time the Civil War was waged!

290. Dec 28: Ancient Australians made immortal art w/ fungus! (h/t @JenLucPiquant )  This is fascinating because it answers a question so obvious that nobody ever thinks to ask it — why have Australian rock paintings survived so long in such extreme conditions?

ResearchBlogging editor’s selections: Dr. SkySkull’s last post!

skyskull “Dr. SkySkull” selects several notable posts each week from a miscellany of ResearchBlogging.org categories. He blogs at Skulls in the Stars.

Welcome to my final post as the “miscellaneous” ResearchBlogging content editor!  After 1 1/2 years of showcasing some of the highlights of the community, I’ve decided to step down to pursue other interests (i.e. focus a bit more on my own blogging).  This post is a little late as I’ve just gotten back from my holiday travel to Chicago, but hopefully it will be just as enjoyable!

  • The almond of horror. At his eponymous blog, Neuroskeptic describes a woman with a peculiar brain condition — she literally feels no fear — and what studies of her condition do for neuroscience.
  • Prehistoric zoning. The host of Gambler’s House is working on a graduate degree in city planning, but also worked at the prehistoric city at Chaco Canyon as a guide.  There may not seem to be a great overlap in the two occupations, but teofilo gives a great description of how archaeologists and planners can work together for a greater understanding of both fields.
  • Two stars merge on camera. Professor Astronomy describes an amazing stellar event caught on camera — the collision of two stars and their merger into a new object!

Thanks to all who have read my editor’s selections during my tenure!  I’d also like to take this opportunity to welcome our two new editors, Krystal D’Costa of Anthropology in Practice, Social Sciences Editor, and Sarah Kendrew of One Small Step, Physical Sciences Editor!  Krystal will be posting on Thursdays and Sarah on Mondays; please check out their posts!

Best wishes,

Dr. SkySkull
