You-tube Generation

I like to watch you-tube videos at work, am I alone?

There are so many great and not so great videos out there. I often show clips I find on-line in my classes to initiate class discussions. I had the idea of making our own little documentary a few weeks back. We posted it on You-tube this morning. I can’t take credit for it, since a very talented graduate student actually put it all together. Now that we have a first attempt at a “science documentary” I am interested to get your feedback. See what you think.

Optics basics: Polarization

In a previous ‘basics’ post, I discussed the three major branches of optical science. My specialty, physical optics, involves the study of the wave properties of light. In particular, there are three major phenomena in physical optics: interference, diffraction, and polarization. We’ve talked about the first two of these in earlier posts, and it is time at last to say some words about polarization!

In essence, “polarization” is a fancy way of saying that light is a transverse wave; with that in mind, we begin with a brief discussion of transverse and longitudinal waves.

Richard Marsh’s The Goddess: A Demon

I’ve been on a bit of a Richard Marsh kick lately (I already discussed his books The Beetle and The Joss), reading everything of his that’s available in print. He’s almost completely unknown today, even though he was a highly successful author in the late 1800s/early 1900s.

I’ve almost run out of his books available in hardcopy, and have now turned to Google books to find more of Marsh’s work. I recently finished reading his 1900 horror/mystery novel The Goddess: A Demon, and I give a summary and some impressions of the book after the fold…

Mathematicians on Mortgages

In a nice little coincidence, recently two mathematics bloggers have decided to give a bit of a description of the subprime mortgage market crisis.  Neither is an economist, but that’s probably okay, even preferable, considering it was the economists who got us into this mess.

Ben Allen of Plektix has written a two-part discussion here and here, and

Mark Chu-Carroll of Good Math, Bad Math has written a two-part discussion here and here.

All of these articles are worth a read!

Lost divers shamelessly rip off ‘Lost’ and ‘Land of the Lost’!

Last Thursday, a group of divers went missing on what was supposed to be a routine tour dive in Indonesia. On Saturday, all five were rescued from the island of Rinca near Komodo Island, having spent two days surviving on the abandoned island (a more British-centric description can be found here). They ate raw shellfish while waiting to be rescued, and all are in good condition, apart from some dehydration.

The story gets better, though, as anyone familiar with the native inhabitants of Komodo Island might suspect: they had to fend off a Komodo dragon that was showing a little too much interest in them!

“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.
