5/12/2018 23:54 A Trump Appointee Does Something Meritorious: Betsy DeVos is as unqualified and disturbing as the typical Trump cabinet member. But Obama’s Title IX legacy was so disastrous that her proposed reforms urgently need support from everyone who cares about fairness and justice.

2/11/2018 22:44 Tailwind: style your site without writing any CSS!: Julia Evans is enthusiastic about this library of CSS utility classes. My own work seems to be evolving toward creating my own less systematic version of this. I’m still not sure whether I think this approach is a good idea, but if you do, Tailwind is a well-regarded implementation.

7/10/2018 12:43 Jamal Khashoggi: Turkey says journalist was murdered in Saudi consulate: As the two vile governments argue over what happened in this bizarre incident, two facts seem clear: the Saudi government would not have been reckless enough to do what they are accused of as a result of an official act; but, in the heat of the moment, someone in the embassy may have lost his cool (remember the words of Casper Gutman).

9/8/2018 12:46 Julia 1.0 is here: Back in 2014 I thought that Julia might become the preferred language for numerically intensive computing. It’s already made impressive inroads in this area, and the arrival of v.1.0, with its promise of a long future of non-breaking language development, can only accelerate its adoption.
1/8/2018 11:45 The “Liberator” doesn’t work: If you’re foolish enough to pull the trigger on one of these, the only thing you are likely to damage is your hand. The uselessness of these “guns” was pointed out in this 2013 article—and yet they are not entirely useless, for they are now providing a prop to help politicians pretend that they are doing things to protect us.
27/7/2018 12:02 There Was No Big Bang Singularity: Descriptions of the Universe’s origins as a singularity, although common even on the part of cosmologists, are out of date.

Subject: A brief history of quantum alternatives

I never react on articles on internet (too few hours in a day) but you've made the exception. What a brilliant sum-up. I strongly suggest to take your place in front of a class room.

Thank you for those kind words. I hope I deserve them.

Subject: A brief history of quantum alternatives

I was wondering if you've ever ran across the book "Quantum Philosophy" by the French physicist Roland Omnés. I ran across it a number of years ago by accident and picked it up thinking it would be one of those fun but flawed New Agey books on the subject. It is a bit old (the original French edition is dated 1994), but since he is just doing basically an intro to quantum physics (well, philosophy actually), I think it holds up very, very well. And he does this through a giving a history, starting with Classical logic/math/physics etc before going on the Formalism of the same things and showing just how prevailing theories broke down. He really doesn't begin talking quantum until at least half-way thru the book. And then he is just talking the basics of the physics. He is more interested, really, in the philosophy of science. Two parts in the book that I really like is how he manages to dismiss the Schrödinger Cat problem in less than a page and that there is a chapter titled 'Recovering Common Sense'. But he is not done there. There is a lot more about modern scientific philosophy with, naturally a section on Thomas Kuhn. All in all, a book I truly love that I don't understand just why is not more widely known.

I've seen references to this author, but never read the book. Thank you for the recommendation, I'll keep it in mind.

Dear Robert,

I was very pleased to get your kind note. It's always a great satisfaction to learn that the results of my toil are well received!

Subject: Turbulence and fractals

I just finished reading your article on the problem of turbulence and was wondering if anyone has considered using fractals to help describe turbulent functions. Fractals came to my mind after looking at the images as well as the reading about some of the properties of turbulence. Anyway, thank you for an enjoyable article.


In my very limited understanding of this area, fractal geometry has been used to describe turbulent fields, but, as far as I know, has not led to increased power of prediction. Here is a serious review of the situation as of 1991:
