More on Nobel laureates and fluid dynamics research

Continuing on the theme of Nobel laureates and fluid dynamics research, I recently stumbled upon a cosmology paper by Steven Weinberg (Physics, 1979) published in 1971, dealing with relativistic fluid dynamics.  The paper begins with a rederviation of the fundamental equations of special relativistic fluid dynamics, then moves on to discuss radiative transport coefficients, and generalizes the equations to general relativity.  Of course he goes on to deal with some astrophysical matters.  Weinberg cites this paper in the last book he published before he died, his textbook on modern physics (2021).  This book has an entire section on transport phenomena (Sec. 2.5), part of the chapter on thermodynamics and kinetic theory.

Speaking of textbooks, Kip Thorne (Physics, 2017) and Roger Blandford published a monumental course, Modern Classical Physics, the year Thorne won the Nobel Prize.  Part V of the book is dedicated to fluid dynamics, and it consists of seven chapters:

  • Foundations of Fluid Dynamics
  • Vorticity
  • Turbulence
  • Waves
  • Compressible and Supersonic Flow
  • Convection
  • Magnetohydrodynamics

They, too, give space to the special relativistic formulation of fluid mechanics, in addition to the usual Newtonian formulation.  It is notable that Part IV of the book is on elasticity, so they truly cover continuum mechanics writ large.  Perhaps the late Jerry Gollub would be pleased.

Nobel laureates and fluid dynamics research revisited

Eight years ago I blogged about Nobel laureates and fluid dynamics research, and last year I commented on a letter in Physics Today complaining that the Nobel Prizes neglect fluid dynamics research.  Today I just stumbled about another Nobel laureate who evidently did some research in fluid dynamics, namely Frank Wilczek (Physics, 2004).  Evidently back in the 1980s he published research with Alfred Shapere on the physics of swimming, published in the field's top journal, the Journal of Fluid Mechanics.  I've included citations below.  

Readers, if you know of other examples besides those I've written about here on DTLR, I'd love to know about them.

Big game hunting in bacteriology: Thiomargarita magnifica

When this blog started in 2013, my third post was about giant viruses.  In an issue of Science last month, we read about the discovery of giant bacteria, large enough to be seen with the naked eye.  Thanks to reporter Elizabeth Pennisi for an excellent overview of the discovery.

Careers: academy or industry?

This month's issue of Physics World includes an article by Joanna Zajac, "Industry or Academia:  How to Choose Your Own Path".  Every word rings true to me.  I strongly encourage readers contemplating a science career (or career change) to read her commentary.

The Oxford Handbook of Newton

Happy New Year.  In my November post on scientists and the Cambridge Companions, I made a passing reference to the Oxford Handbooks series.  As far as I knew then, there is no Oxford Handbook dedicated to a physicist.  I have discovered just this evening, however, that an Oxford Handbook of Newton is in development; individual chapters are being posted online as they are finalized.

I would also like to call attention to an unnamed philosophy series from Cambridge University Press, whose volumes are titled Interpreting _____:  Critical Essays.  Two physicists (Newton and Mach) and one mathematician (Godel) have volumes devoted to them in that series.  There are also volumes on other philosophers including specialists in the philosophy of science, including Kuhn and Feyerabend.

"New data from old poop"

Don't you want to learn about changes to our microbiome over time, by examining paleofeces?  You do.  See the commentary by Andrew Curry from earlier this year.

Scientist biography series

Somewhat related to the theme of recent posts (here and here), let's look at a couple of scientific biography series from the two gigantic British academic presses, Cambridge and Oxford.  

Cambridge University Press has a Cambridge Science Biographies series.  At the time of writing, there are ten volumes listed in print on the website.  These are serious biographies running into the hundreds of pages.  There are three devoted to physicists:  Galileo, Newton, and Ampere.  There are three for chemists:  Lavoisier, Humphry Davy, and Justus von Liebig.  There are two for biologists:  Charles Darwin and Thomas Huxley.  Rounding out the set are Henry More and Mary Somerville.  I've always understood that Somerville was a mathematician, but the table of contents indicated she worked in physical and Earth sciences as well.  Henry More was a name unfamiliar to me.  Apparently he is primarily viewed as a philosopher, but he pursued experimental science as well, and was an influence on Newton.  Since these are substantial biographies, I would imagine no attempt is made to cover all the major figures in science.  Otherwise the choice of Ampere over Einstein would be most curious!

Oxford Portraits in Science are shorter biographies intended for young adult readers.  At the time of writing I see 17 volumes in print.  However, I own copies of the volumes on Faraday and Einstein, and they list additional volumes that may be out of print.  I will  include them here and group them collectively as follows:

Biologists & physiologists:  Charles Darwin, Gregor Mendel, William Harvey, Edward Jenner, Louis Pasteur, Crick & Watson (a single volume covering both).

Chemists: Marie Curie, Linus Pauling.

Physicists & astronomers:  Copernicus, Kepler, Galileo, Newton, Ben Franklin, Faraday, Joseph Henry, Curie, Rutherford, Fermi, Einstein

Inventors and technologists:  Alexander Graham Bell, Charles Babbage, Thomas A. Edison.

Behavioral scientists:  Pavlov, Freud.

Anthropologists:  Margaret Mead.

Paleontologists:  Othniel Charles March & Edward Drinker Cope (a single volume covering both).

In the above accounting, I've included the Curie volume under both physics and chemistry; it could be argued that Rutherford should also be so counted.

Here, we might have a greater expectation than with the Cambridge Science Biographies, that the most important, or at least most interesting, scientists be included.  However, none of the chemists in the Cambridge series appear in the Oxford series.  The selection of biologists/physiologists is an excellent one, but could certainly be expanded further.  Again I will focus mainly on the physicists/astronomers.   The Oxford series has an excellent list - all of them are deserving.  As I've stated before, volumes on Tesla and Feynman would probably sell as well, if only they existed.  The inclusion of Franklin and Henry, American contributors to electromagnetic science, raises the question of why non-Americans in this field have not been included (such as Ampere, Oersted, and above all Maxwell).  Again it seems to me that Niels Bohr might deserve a volume.  

Finally, as a dessert for this discussion, what about Princeton University Press's "The Quotable..." series?  These are books of quotations by various authors.  Three scientists are included:  Darwin, Einstein, and Feynman.  Maybe you might consider Jung as a behavioral scientist.  Others in the series include Niccolo Machiavelli, Thomas Jefferson, Henry David Thoreau, and Soren Kierkegaard.  I suppose this is the most subjective of all, since the person in question has to be very "quotable"!
