Link of the Moment

According to an email from SOR, the web site for the XVIth (that's 16th, for those who don't know Latin) Congress of Rheology is now live.  The Congress will take place August 5-10, 2012 in Lisbon, Portugal.

Benoit Mandelbrot, RIP

Beniot Mandelbrot, the father of fractal mathematics, passed away on October 14th.  Applications of fractals in fluid mechancs can be found in the phenomena of viscous fingering and turbulence.
I learned about Mandelbrot when I picked up a book on the basics of fractals [1].  There's a great story about Mandelbrot at IBM.  Hired into their research division, he discovered that the noise in the data transmission was both regular and erratic.  He found that the standard approach to the noise, increasing the transmission signal, would not fix the problem [1,2].  When I first heard this story, I thought it was a fabulous example of a theoretician finding a solution to a real-world problem.  Such solutions are rare, which is why pure theoretical work is hard to find at for-profit companies these days.

Product of the Moment: Teabag Coaster

This product is designed by Yuree Stacy Lim, Jieun Yan, and Sangmin Bae of Korea Advanced Institute of Science and Technology.  It is a specially designed teabag made of compressed paper.  Once the wet bag is put on the coaster, the tea spreads via capillary action through the paper, dying the paper.

Rheological Word of the Moment

The winning word from this year's Scripps National Spelling Bee was stromuhr, which is "a rheometer designed to measure the amount and speed of blood flow through an atery."  Stromuhr combines the German words for "stream" and "clock" and was invented by Carl Ludwig in 1867.  Ludwig (1816-1895) was a German medical researcher who related chemical and physical laws to biological phenomena.

A picture of his stromuhr is shown to the left.

Anamika Veeramani was the winner of the 2010 National Spelling Bee, which was completed this past June.

Accidental Discovery Files (#3)

While working on photosensitive glass, Dr. S. Donald Stokely accidentally overheated a sample.  The resulting product resisted breakage when dropped and could be used directly on the cooktop.  The material was called Pyroceram and was marketed as CorningWare.

Viscosity & Fractals

While doing a little light reading [1], I came across this 1920 poem by Lewis Richardson--

Big whorls have little whorls,
That feed on their velocity;
And little whorls have lesser whorls,
And so on to viscosity.

Several people [1,2] have remarked on this poem's debt to Jonathan Swift's famous flea poem

So, Nat'ralists observe, a Flea
Hath smaller Fleas that on him prey,
And these have smaller Fleas to bite 'em
And so proceed ad infinitum.

Link of the Moment: Chemjobber Blog

Today's link is the Chemjobber blog, which I learned about when John was interviewed about polymer chemistry.  The blog is a continual analysis of the chemistry job market, and is similar to my monthly job reports.  I added the Careerbuilder searches in this month's jobs report after a quick check of the links at Chemjobber.  I recall using Careerbuilder in previous job searches, but I hadn't checked the site recently.

Jobs Report (October 2010)

Using my standard search term "rheolog*", which was conducted on October 1st, there are 26 job positions listed on Monster.com, and there are 12 positions listed on Careerbuilder.com.  The Kraft rheologist job (discussed on August 18th) is not found on either site.  The Wrigley rheologist job (discussed on September 24th) is found on Careerbuilder.  The jobs are found in the following industries--
