Quillen Notebooks

Daniel Quillen, one of the greatest mathematicians of the latter part of the twentieth century, passed away in 2011 after suffering from Alzheimer’s. For an appreciation of his work and an explanation of its significance, a good place to start … Continue reading ?

Quick Links

The Defense Department has awarded a $7.5 million grant to Steve Awodey of CMU, Vladimir Voevodsky of the IAS and others to support research in Homotopy Type Theory and the foundations of mathematics. I had thought that getting DARPA 10 … Continue reading ?

Raising the Bar

If you’re looking for something to do next Tuesday evening here in New York, an event called Raising the Bar has recruited 50 people to give talks at bars around the city. There are some quite interesting talks on the … Continue reading ?

Supersymmetry and the Crisis in Physics

The May issue of Scientific American has a very good cover story by Joe Lykken and Maria Spiropulu, entitled Supersymmetry and the Crisis in Physics (the article is now behind their subscriber paywall, but for those with access to Nature, … Continue reading ?

Ten Years of Not Even Wrong

This blog was started a little bit over ten years ago, and I’ve been intending for a while to write something marking the occasion and commenting on what has changed over the past ten years. I’ve found this mostly a … Continue readi...

Quick Links

Just time at the moment for some quick links. I’ll start with some math news, since there hasn’t been much of that here recently: Matt Baker has the sad news here of the death of Berkeley mathematician Robert Coleman recently, … Continue reading ?

Sheldon Gives Up On String Theory

Ten years ago I wrote here about the news that Witten had finally given up on string theory. Today I just heard a similar but even more dramatic rumor: next week’s episode of The Big Bang Theory features string theorist … Continue reading ?

A Brief History of String Theory

On the long plane flight to Italy I had the chance to read the recently published A Brief History of String Theory: From Dual Models to M-theory by philosopher of science Dean Rickles. The book deals with the history of … Continue reading ?

B-mode News

While I was away on vacation, the big news in physics was the BICEP2 result on B-modes in the CMB. Maybe it’s just as well I wasn’t available to blog about this, since inflation and cosmology aren’t at all my … Continue reading ?

Rainy Day Posting

My spring break vacation is not quite over but, after 10 days of spectacularly beautiful weather, it’s now raining hard here today and I’ve got some time indoors to write something. First some quick links to things I’ve seen in … Continue reading ?

Spring Break

I’m leaving for a spring break vacation in Northern Italy tomorrow afternoon, and will shut down comments while I’m away. Back in two weeks. Some events that will occur while I’m away that might be of interest: The 2014 Templeton … Continue reading ?

Multiverse Mania at Wikipedia

The quality of Wikipedia entries about mathematics is often quite good, but unfortunately the same cannot be said for their entries about physics. I happened to take a look today at the Wikipedia entry for Multiverse, which is an outrageously … Continue reading ?

Various and Sundry

It seems to be too early for April Fool’s day, and yet the arXiv has Dark Matter as a Trigger for Periodic Comet Impacts by Lisa Randall and Matt Reece, a preprint described as “Accepted by Physical Review Letters, 4 … Continue reading ?

All Hail Resonaances

I’m delighted to see Jester back in action, providing great material on the current state of HEP physics, with, over the past week and a half: A sober look at the sparse prospects for near-term (i.e. 2014) input from experiment, … Continue reading ?

Quantum Mechanics, The Theoretical Minimum

In recent years Leonard Susskind has been giving an excellent series of lectures on basic ideas of theoretical physics, under the title The Theoretical Minimum. The general idea seems to be to provide something in between the usual sort of … Continue reading ?

More Quick Links

First, a couple of examples of recent progress in mathematics Terry Tao has some new ideas about the Navier-Stokes equation. See his blog here, a paper here, and a story by Erica Klarreich at Quanta here. I’ve been hoping to … Continue reading ?

US HEP Theory Funding News

Laurence Yaffe has gathered some information about DOE funding of US HEP theory groups, showing sharp drops (average 23%) in such funding for groups reviewed in FY2013 and FY2014. These drops imply serious reductions in the numbers of theory graduate … Continue reading ?

The Multiverse, Evidence and Theology

Yes, this multiverse business is tedious, but since it is becoming mainstream physics, with colloquium talks here at Columbia devoted to it, and the Columbia University Press publishing books about it, seems to me that someone at Columbia should be … Continue reading ?

More Links, Interesting and Tedious

First some links to interesting things: There’s a fascinating interview with Deligne in the latest AMS Notices. Alexandre Grothendieck: A Mathematical Portrait includes some great expository pieces about the mathematics developed by Grothendieck. There’s also available Grothendieck’s own Esquisse Thématique, … Continue reading ?

The Perfect Wave

Sometimes when I have come across claims of exotic phenomena at the far-out edge of the field of BSM physics based on branes and string theory (like time travel, or brane-world explanations of the bad OPERA result), my initial reaction … Continue reading ?
