“Aether Drag” and Moving Images: A different sort of “twin paradox”

ResearchBlogging.org

Note: I’ve bumped this post in a probably futile attempt to get it aggregated by Research Blogging.

It’s a little challenging to blog about contemporary optics research, as much of the work being done, though interesting, is of an extremely technical nature and not of much excitement for a general blogging audience.

There are a few research groups out there, however, that work on fundamental optical problems which are conceptually simple but surprisingly subtle in their implications, and one such group, based in Glasgow, recently had a paper come out with the provocative title, “Aether Drag” and Moving Images.

The title is provocative because one hardly expects to see papers with the word ‘aether’ appearing in prestigious journals like Physical Review Letters anymore. ‘Aether’, of course, refers to the incorrect and obsolete idea that light is the vibration of a mysterious, ethereal mechanical substance which permeates all space. The term ‘aether drag’ is a historical holdover, and now is used to refer to the behavior of light fields in moving media. The Glasgow group has taken a fascinating new look at this phenomena, and I provide some details below the fold…

Name the ‘carnival of the classics’!

I’ve been chatting with Coturnix over at A Blog Around The Clock about preparing a new blog carnival related to classic papers. One of the first questions that came up: what do we name this new carnival? Coturnix suggested that I take suggestions from the blogging community; the only criterion is that the name shouldn’t include the word ‘carnival’ in it!

So what do people think? What would be a good name for a regular ‘classic scientific papers’ blog event?

Also, how often should the carnival take place? The obvious thought is once a month, but I also can see a good case for every other month.  (More time for people to do research.)

Finally, I’ll be putting together a home page for the carnival to post announcements (though the carnival itself will be hosted on individual blogs). I’d like to put together a nice header for the home page, with images taken from ‘classic’ papers. If you have any recommendations of things that would look nice in a header, feel free to suggest them in the comments.

The Civic Scientist

I think I love a challenge but in truth I hate failing, and will usually not undertake a task unless I think I have a good shot at excelling at it. That may be the reason why when my friend and former neighbor gg suggested I write a guest blog entry on his site, I said NO WAY! What if everyone thought I was boring or worse…stupid! I definitely have not mastered correct punctuation and grammar (gg, will you proof read this for me?) Well, maybe my friend gg is the brave one for letting me post my first ever blog post on his site. I changed my mind about the entry a few weeks back when I was at the Council for Chemical Research annual conference in St. Louis, and heard a most impressive talk by Bill Hammack, Professor in Chemical and Biomolecular Engineering at the University of Illinois-Urbana, entitled “How should chemical scientists and engineers talk to the public?” Bill Hammack is widely known for his pieces on public radio http://www.engineerguy.com/ Interestingly, Bill points out when discussing demographics “If you are over 40, you might well listen to public radio, under 40 almost no chance!” I do not listen to public radio and had never heard of Bill Hammack, so you can guess what age group I belong to.

One component of Bill’s talk was the idea of the “Civic Scientist”. Bill went on to say that the term was coined by Neal Lane the former director of NSF, when referring to researchers that made it their mission to reach out to the public, which he argued is essential to continued public support of science. What really caught my attention was the suggestion that we as a new generation of scientists have an unprecedented opportunity to reach out to the public because of the internet. According to Hammack, You Tube gets 2.5 million hits a day! That is when it all made sense to me why my friend gg spent so much time posting blog entries on the internet. In an effort to try and live up to the concept of the Civic Scientist, I will begin posting chemistry videos on You Tube. So look out for our first attempts at utilizing this new media outlet in the next few weeks and any feedback/comments would be greatly appreciated.

A little bit about me, if anyone is interested: I am, as my name implies, a chemist from Cairo. My husband is also a chemist but he is from N. Ireland and we met as postdocs. I think only in America can an Irishman and an Egyptian find themselves at a university in the middle of nowhere and fall in love. I used to be a faculty member at the same institution as gg, but have since left for a new position that is more management than research. I am still active in teaching and science education.

Welcome cairochemist!

Just a quick note: I’ve been trying to convince some of my colleagues for some time to do some guest blogging here. One of them, who will be known as cairochemist, has fallen for my spiel… ahem… *cough* *cough*… has agreed to do so! Cairochemist be doing some posts on chemistry related topics as well as anything else that comes to mind. Look for posts beginning sometime in the next few days!

George Brewer’s The Witch of Ravensworth

A some time back I wrote a blog post about The Animated Skeleton, an early Gothic horror novel written in 1798 and reprinted for the first time by Valancourt Books. Though fascinating and enjoyable, ‘Skeleton is not an easy read, due to the writing style. It was suggested that I should try The Witch of Ravensworth as a more accessible Gothic read, so I did!

Written in 1808 by George Brewer, The Witch of Ravensworth is not that much more recent than ‘Skeleton, but the prose is significantly different and flows much better. The structure of the story, interestingly enough, is quite similar to ‘Skeleton in general, though it differs in the specifics.

The 2008 “Classic Science Papers” Challenge is done!

The deadline for the “Classic Science Papers” challenge has passed! The collection of entries will be permanently bookmarked here, for future reference.

Entries ranged over a wide variety of disciplines: biochemistry, biology, geology, neuroanatomy, medicine, physics, physiology, and psychology. Entries ranged from studies of works done in 1543 through 1973 (‘classics’ can of course be from any era). Entries came from workers from the undergraduate to the faculty level.

It’s amazing how much interesting history is out there in old papers that rarely get discussed in detail any more; I learned a heckuva lot from every entry, and I’m grateful that everyone took the time to write up nice entries and submit them. For those who want the ‘classics’ to continue, Coturnix has suggested turning this into a regular blog carnival, and that sounds like a great idea that we’ll hopefully make happen.

Thanks again to ecoli at thoughts from gut bacteria, Mary at The OpenHelix Blog, Gerlach at Off Resonance, Coturnix at A Blog Around The Clock, Epicanis at The Big Room, Winawer at Mild Opinions, Tuff Cookie at Magma Cum Laude, coconino at Ordinary High Water Mark, BrianR at Clastic Detritus, barnowl at Guadalupe Storm-Petrel, catatau at catatau, Arunn at nonoscience, Tom at Swans on Tea, SciCurious at Neurotic Physiology, Dave Munger at Cognitive Daily, and podblack at PodBlack Blog.

Edgar Allan Poe’s The Premature Burial and its references

Of all of the works of Edgar Allan Poe’s, one of my favorites is The Premature Burial (1844). The narrator of the story is a man who suffers from cataleptic attacks which leave him insensate and seemingly lifeless. He develops a fear of dying and of the worst form of death: being buried alive.

I recently took another look at the tale, in particular at some obscure books which are referenced within it. In this post I take a look at each of these references, after a spoiler-laden discussion of the story. If you haven’t read The Premature Burial yet, I encourage you to do so; it’s not quite what you think it is. Then come back here and I’ll have a few words about it.

Seiches in Chicago

This is interesting. Only a couple of weeks after I wrote about the phenomena of seiches, powerful winds on Lake Michigan produced a seiche which washed up on the Chicago shoreline (h/t my Mom). This seiche was not devastating or deadly, involving only 26-inch variations in water level. Unfortunately the storms which produced the seiche did a lot more damage, spawning tornados, huge hail and ripping down power lines.

A couple of days left for the ‘challenge’!

Just thought I’d put out a reminder that the official deadline for the ‘classic science paper challenge’ is only two days away: May 31st.  It will probably take me a couple of days to write up a wrap-up post about the ‘challenge’, so there’s a little leeway in submitting.

We’ve got such great entries so far; I encourage everyone to take a look at the links page!

Grounded!

Well, I’m back from my skydiving adventure at the Memorial Day Boogie at Emerald Coast Skydiving Center.  Just like last year, the staff was friendly and helpful, and I managed to get eight jumps on the beach.  There’s nothing like landing in front of the Flora-Bama bar and getting a round of cheers and applause from a bunch of bikers!

I should have video of some of the jumps next week, and I’ll post them asap.

Some skydivers were not so lucky over the weekend; Michael Fournier, the French skydiver I’ve written about before, was planning to make his record-setting freefall over Canada from 130,000 feet.  Unfortunately, the attempt never got off the ground; an unexplained electrical discharge disconnected the high-altitude balloon from the gondola before takeoff, and it drifted to the ground 40 km away.

This malfunction put an end to this attempt to set the world-record freefall; the cost of the failure is estimated at 600,000 euros, but Fournier is hoping to try again in August.
