📖 On page 95 of 206 of The Science of the Oven by Hervé This

Oh, if only more of my cookbooks had fantastic sentences like this one:

Now the flow of a liquid in a canal varies as the fourth power of the diameter.

Then there’s this lovely statement, which is as applicable to jellies and consommés as it is to our political leaders:

Today, as heirs to the (political) ancien regime, we all want jellies, like bouillons and consommés, to be transparent.

I’ll note that chapter 4 has some interesting recipes as well as one or two long-term experiments which may be interesting to try.

Peter Webb’s A Course in Finite Group Representation Theory

A Course in Finite Group Representation Theory by Peter WebbPeter Webb (math.umn.edu)
Download a pre-publication version of the book which will be published by Cambridge University Press. The book arises from notes of courses taught at the second year graduate level at the University of Minnesota and is suitable to accompany study at that level.

“Why should we want to know about representations over rings that are not fields of characteristic zero? It is because they arise in many parts of mathematics. Group representations appear any time we have a group of symmetries where there is some linear structure present, over some commutative ring. That ring need not be a field of characteristic zero.

Here are some examples.

  • […]
  • In the theory of error-correcting codes many important codes have a non-trivial symmetry group and are vector spaces over a finite field, thereby providing a representation of the group over that field.”

Physicists Hunt For The Big Bang’s Triangles | Quanta Magazine

“The notion that counting more shapes in the sky will reveal more details of the Big Bang is implied in a central principle of quantum physics known as “unitarity.” Unitarity dictates that the probabilities of all possible quantum states of the universe must add up to one, now and forever; thus, information, which is stored in quantum states, can never be lost — only scrambled. This means that all information about the birth of the cosmos remains encoded in its present state, and the more precisely cosmologists know the latter, the more they can learn about the former.”

In Memoriam: Millard Kaufman, WWII Veteran and Front for Dalton Trumbo

On Veteran's day, a memoriam of writer Millard Kaufman.


n Veterans Day this year, which lands very near the release of the film Trumbo starring Bryan Cranston, I thought I’d take a moment to remember my old friend and mentor Millard Kaufman.

Millard not only fought for us in the war, but when he came back home he helped to defend our right to free speech and our ability to pursue happiness in a very fundamental way in his career as a screenwriter.  I often hear friends in the entertainment industry say, “This isn’t brain surgery, we’re not saving lives, here.” but in a great sense Millard was doing that in small steps throughout his career. Millard Kaufman enlisted in the Marines in 1942, served on Guadalcanal, landed at Guam with the 1st Marine Brigade (Provisional) where he wrote an article for the Marine Corps Gazette about the battle, then participated in the Battle of Okinawa with the 6th Marine Division.

Millard Kaufman

I met Millard 20 years ago in 1995 on a trip to Los Angeles with Matt Gross while we were ostensibly programming the 1995 Milton S. Eisenhower Symposium entitled “Framing Society: A Century of Cinema” which coincided with the 100th anniversary of film.  Dr. John Irwin, the long-time head of the Writing Seminars Department at Johns Hopkins, had provided us with a long distance introduction as Millard was a Hopkins alum from the class of ’39. So we met him at his home in the Hollywood Hills looking out over a forested sanctuary. Over our first simple tuna fish sandwich lunch, we began a friendship that spanned the next decade and a half.

Most may remember Millard Kaufman, if at all, as the co-creator of the cartoon character Mr. Magoo, who he based on his uncle, while many others will know his Academy Award nominated films Take the High Ground (1953) or Bad Day at Black Rock (1955). I’ll always remember him for his charm, his wry wit, his ability to swear comfortably in any company, and his sense of fairness.

Millard Kaufman in his youth

Apparently Hollywood itself has glossed over his contribution to helping to maintain Dalton Trumbo’s writing career in the recent release of Trumbo (2015), in which he isn’t mentioned (or portrayed on screen). [I’ll note here that I haven’t yet seen the movie, and may boycott it for the slight.] It is here in which Kaufman’s strong internal moral compass pressured him to help ensure Trumbo’s freedom of speech and, in part, his writing career. In short, the House Un-American Activities Committee’s (HUAC) pressured Trumbo which resulted in Trumbo’s being blacklisted in Hollywood and effectively destroying his writing career.

Trumbo and Kaufman shared the same agent at the time, George Willner. One day, relatively early in Kaufman’s career, Willner approached him to see if he would be willing to put his name on the script Gun Crazy that would turn into the 1950 film-noir crime classic to allow it to get made. As Millard told me many times, “I didn’t have much sense then, but at least I had sense enough to say, ‘Let me talk it over with Laurie’ [his wife].” “But we discussed it and we believed it was rotten that a man couldn’t write under his own name,” Kaufman told Daily Variety in 1992.  That same year Kaufman, a board member of WGAw, officially requested that the Writers Guild take his name off the credits and replace it with Dalton Trumbo’s name. Kaufman’s fronting for Trumbo helped allow the film to get made, and Trumbo’s career to continue on, even if in the dark. As a board member of the Writer’s Guild Millard helped to restore credits to many writers of the blacklist era who were similarly slighted as a result of their politics at the time. It’s a travesty, that a film gets made highlighting this exact period in Trumbo’s life, but Millard’s small contribution to it has been all but forgotten.  Fortunately there are enough who do remember to tell the story.

Millard Kaufman

When I think of Millard and his various contributions, my favorite is always that he wrote the stunning script for Bad Day at Black Rock (MGM, 1955), a superb Western suspense film starring Spencer Tracy as a one-armed veteran facing mysterious enemies in a small desert town. The film shows how post-World War II America could be be both horrifyingly racist and cowardly, but it also showed a way out through Tracy’s character which always reminds me of Millard’s high-mindedness. It was such a great film, I was personally honored to screen it on November 3, 1995, as the premiere film in Shriver Hall after we had mounted a year-long renovation of the film equipment, screen, and sound system. The day before we were all honored to have Millard speak on “Censorship in Film” as part of the Milton S. Eisenhower Symposium.

For those who never had the chance to meet him, I’m including a short 3 minute video of several clips of him talking about a variety of topics.  The Millard portrayed here is the no-holds barred man I’ll always remember. Thanks for fighting for all of us, Millard!


For those looking for more information about Millard Kaufman, I’ll include the following articles:

Sir Francis Bacon smacks down Republican party front-runners

Advice for laying down the law of the land


s I watch the unfolding of the 2016 presidential election, I find myself wondering more and more where I can register to vote for the “scientific party?”

The electorate seems to want to focus primarily (only?) on the Judeo-Christian principles upon which our country was founded. Though I have no qualm with these principles, they seem to miss the firmer and primary base upon which the country was built at the dawn of the Age of Reason.

Introduction to Lie Groups and Lie Algebras (Part 2) | UCLA Extension

Dr. Mike Miller has just opened up registration for the second course in the series. His courses are always clear, entertaining, and invigorating, and I highly recommend them to anyone who is interested in math, science, or engineering.

Dr. Mike Miller, who had previously announced a two quarter sequence of classes on Lie Groups at UCLA, has just opened up registration for the second course in the series. His courses are always clear, entertaining, and invigorating, and I highly recommend them to anyone who is interested in math, science, or engineering.

Philosophy is written in this grand book, the universe which stands continually open to our gaze. But the book cannot be understood unless one first learns to comprehend the language and read the letters in which it is composed. It is written in the language of mathematics, and its characters are triangles, circles and other geometric figures without which it is humanly impossible to understand a single word of it; without these, one wanders about in a dark labyrinth.

Galileo Galilee (1564–1642) in Il saggiatore (The assayer)

Prior to the first part of the course, I’d written some thoughts about the timbre and tempo of his lecture style and philosophy and commend those interested to take a peek. I also mentioned some additional resources for the course there as well.  For those who missed the first portion, I’m happy to help fill you in and share some of my notes if necessary. The recommended minimum prerequisites for this class are linear algebra and some calculus.

Course Description

A Lie group is a differentiable manifold that is also a group for which the product and inverse maps are differentiable. A Lie algebra is a vector space endowed with a binary operation that is bilinear, alternating, and satisfies the so-called Jacobi identity. This course is the second in a 2-quarter sequence that offers an introductory survey of Lie groups, their associated Lie algebras, and their representations. Its focus is split between continuing last quarter’s study of matrix Lie groups and their representations and reconciling this theory with that for the more general manifold setting. Topics to be discussed include the Weyl group, complete reducibility, semisimple Lie algebras, root systems, and Cartan subalgebras. This is an advanced course, requiring a solid understanding of linear algebra, basic analysis, and, ideally, the material from the previous quarter.Internet access required to retrieve course materials.

Information Theory is the New Central Discipline

Information Theory is the new central discipline. by Nassim Nicholas Taleb (facebook.com)

INFORMATION THEORY is the new central discipline. This graph was from 20y ago in the seminal book Cover and Thomas, as the field was starting to be defined. Now Information Theory has been expanded to swallow even more fields.

Born in, of all disciplines, Electrical Engineering, the field has progressively infiltrating probability theory, computer science, statistical physics, data science, gambling theory, ruin problems, complexity, even how one deals with knowledge, epistemology. It defines noise/signal, order/disorder, etc. It studies cellular automata. You can use it in theology (FREE WILL & algorithmic complexity). As I said, it is the MOTHER discipline.

I am certain much of Medicine will naturally grow to be a subset of it, both operationally, and in studying how the human body works: the latter is an information machine. Same with linguistics. Same with political “science”, same with… everything.

I am saying this because I figured out what the long 5th volume of the INCERTO will be. Cannot say now with any precision but it has to do with a variant of entropy as the core natural generator of Antifragility.

[Revised to explain that it is not *replacing* other disciplines, just infiltrating them as the point was initially misunderstood…]

Nassim Nicholas Taleb via Facebook

[My comments posted to the original Facebook post follow below.]

I’m coming to this post a bit late as I’m playing a bit of catch up, but agree with it wholeheartedly.

In particular, applications to molecular biology and medicine are really beginning to come to a heavy boil in just the past five years. This particular year is the progenitor of what appears to be the biggest renaissance for the application of information theory to the area of biology since Hubert Yockey, Henry Quastler, and Robert L. Platzman’s “Symposium on Information Theory in Biology at Gatlinburg, Tennessee” in 1956.

Upcoming/recent conferences/workshops on information theory in biology include:

At the beginning of September, Christoph Adami posted an awesome and very sound paper on arXiv entitled “Information-theoretic considerations concerning the origin of life”  which truly portends to turn the science of the origin of life on its head.

I’ll note in passing, for those interested, that Claude Shannon’s infamous master’s thesis at MIT (in which he applied Boolean Algebra to electric circuits allowing the digital revolution to occur) and his subsequent “The Theory of Mathematical Communication” were so revolutionary, nearly everyone forgets his MIT Ph.D. Thesis “An Algebra for Theoretical Genetics” which presaged the areas of cybernetics and the current applications of information theory to microbiology and are probably as seminal as Sir R.A Fisher’s applications of statistics to science in general and biology in particular.

For those commenting on the post who were interested in a layman’s introduction to information theory, I recommend John Robinson Pierce’s An Introduction to Information Theory: Symbols, Signals and Noise (Dover has a very inexpensive edition.) After this, one should take a look at Claude Shannon’s original paper. (The MIT Press printing includes some excellent overview by Warren Weaver along with the paper itself.) The mathematics in the paper really aren’t too technical, and most of it should be comprehensible by most advanced high school students.

For those that don’t understand the concept of entropy, I HIGHLY recommend Arieh Ben-Naim’s book Entropy Demystified The Second Law Reduced to Plain Common Sense with Seven Simulated Games. He really does tear the concept down into its most basic form in a way I haven’t seen others come remotely close to and which even my mother can comprehend (with no mathematics at all).  (I recommend this presentation to even those with Ph.D.’s in physics because it is so truly fundamental.)

For the more advanced mathematicians, physicists, and engineers Arieh Ben-Naim does a truly spectacular job of extending ET Jaynes’ work on information theory and statistical mechanics and comes up with a more coherent mathematical theory to conjoin the entropy of physics/statistical mechanics with that of Shannon’s information theory in A Farewell to Entropy: Statistical Thermodynamics Based on Information.

For the advanced readers/researchers interested in more at the intersection of information theory and biology, I’ll also mention that I maintain a list of references, books, and journal articles in a Mendeley group entitled “ITBio: Information Theory, Microbiology, Evolution, and Complexity.”
