The new Electron-Ion Collider could solve the mystery of how matter holds together

When the Nobel Prize-winning US physicist Robert Hofstadter and his team fired highly energetic electrons at a small vial of hydrogen at the Stanford Linear Accelerator Center in 1956, they opened the door to a new era of physics. Until then, it was thought that protons and neutrons, which make up an atom’s nucleus, were the most fundamental particles in nature. They were considered to be “dots” in space, lacking physical dimensions. Now it suddenly became clear that these particles were not fun...

Take an Intellectual Odyssey with a Free MIT Course on Douglas Hofstadter’s Pulitzer Prize-Winning Book Gödel, Escher, Bach: An Eternal Golden Braid

In 1979, mathematician Kurt Gödel, artist M.C. Escher, and composer J.S. Bach walked into a book title, and you may well know the rest. Douglas R. Hofstadter won a Pulitzer Prize for Gödel, Escher, Bach: an Eternal Golden Braid, his first book, thenceforth (and henceforth) known as GEB. The extraordinary work is not a treatise on mathematics, art, or music, but an essay on cognition through an exploration of all three — and of formal systems, recursion, self-reference, artificial intelligence, e...

Citizenship, Civil Rights, and the (Grass)Roots of Constitutional Revolution

For the Symposium on Kate Masur, Until Justice Be Done: America's First Civil Rights Movement, From the Revolution to Reconstruction (W. W. Norton & Company, 2021). William J. Novak             In an influential article on “History and the Social Sciences,” Richard Hofstadter set an imposing standard for judging the best historical work.  Channeling the anxieties of every historian, Hofstadter criticized both traditional narrative histories where authors “rarely hesitate to retell a story tha...

Constantly Wrong: Filmmaker Kirby Ferguson Makes the Case Against Conspiracy Theories Discordian writer and prankster Robert Anton Wilson celebrated conspiracy theories as decentralized power incarnate. “Conspiracy is just another name for coalition,” he has a character say in The Historical Illuminatus Chronicles. According to Wilson, any sufficiently imaginative group of people can make a fiction real. Another statement of his sounds more ominous, read in the light of how we usually think about conspiracy theory: “Reality is w...

Why the 'Protocols of the Elders of Zion' is still pushed by anti-Semites more than a century after hoax first circulated

An anti-Semitic hoax more than a century old reared its ugly head again as the Republican National Convention was underway last week.Mary Ann Mendoza, a member of the advisory board of President Trump’s reelection campaign, was due to speak on Aug. 25. But she was suddenly pulled from the schedule after she had retweeted a link to a conspiracy theory about Jewish elites plotting to take over the world.In her now-deleted tweet, Mendoza urged her roughly 40,000 followers to read a lengthy thread t...

Ultracold gases in time-dependent magnetic fields

Zk Noor Nabi from Zhejiang University, China and co-workers from the Indian Institute of Technology studied the phase transition between the Mott insulating (MI) and superfluid (SF) states of an ultracold gas in a time-dependent magnetic field. Their results, published in EPJ B, show that the energy spectrum of the gas loses symmetry - and the characteristic 'Hofstadter's butterfly' pattern - in the fluctuating magnetic field.

Bret Stephens and the Paranoid Style

I graduated from college in 1959, a few years before Richard Hofstadter's essay on The Paranoid Style in American Politics came out in Harper's. As an associate in a Pasadena (California) church, the conspiracy theories of the John Birch Society were driving me nuts. One of the promulgators of conspiracy, a retired naval officer and member of the "society" was teaching in adult classes. The senior minister, a nice guy, but utterly gutless, let it go on and on. I was a history major, so I...

Spectroscopic signatures of localization with interacting photons in superconducting qubits

Quantized eigenenergies and their associated wave functions provide extensive information for predicting the physics of quantum many-body systems. Using a chain of nine superconducting qubits, we implement a technique for resolving the energy levels of interacting photons. We benchmark this method by capturing the main features of the intricate energy spectrum predicted for two-dimensional electrons in a magnetic field—the Hofstadter butterfly. We introduce disorder to study the statistics of th...

High-temperature quantum oscillations caused by recurring Bloch states in graphene superlattices

Cyclotron motion of charge carriers in metals and semiconductors leads to Landau quantization and magneto-oscillatory behavior in their properties. Cryogenic temperatures are usually required to observe these oscillations. We show that graphene superlattices support a different type of quantum oscillation that does not rely on Landau quantization. The oscillations are extremely robust and persist well above room temperature in magnetic fields of only a few tesla. We attribute this phenomenon to ...

Conspiracist Nation, Population: Us.

By Isaac Butler In the weeks just prior to November, we entered an odd phase of electoral politics, one that I hadn’t seen before, one of pure conspiracism. Three different conspiracy theories clamored for purchase on the rocky cliffs of our public imagination. The first alleged that the Clinton Foundation traded access to then-Secretary of State Clinton for donations, that Hillary Clinton may have used her position at State to help Clinton Foundation donors in ways that were improper, and that ...

We Bet You Never Noticed This Detail On The Big Bang Theory

The Big Bang Theory has amassed a seriously devoted, almost rabid, following. There are Tumblrs devoted to Sheldon Cooper's comic-inflected wardrobe, 'shippers writing novellas about Penny and Leonard, and the series even has its own conventions — which is super-meta, since the show riffs on Comic-Con and other events like it all the time.However, even the most die-hard fans might not know this one detail, which has been constant since the series' pilot episode: Leonard Hofstadter's glasses hav...

M.C. Escher Cover Art for Great Books by Italo Calvino, George Orwell & Jorge Luis Borges

The writer David Auerbach once posted a fascinating inquest on left-brained literature, an examination of what he calls “a parallel track of literature that is popular specifically among engineers,” excluding genre fiction (science- or otherwise), with an eye toward “which novels of some notoriety and good PR happen to attract members of the engineering professions.” Favored author names turn out to include Richard Powers, Umberto Eco, Haruki Murakami, William Gibson, Italo Calvino, and Jorge...

The Anti-American

"I am, have been, and will be only one thing--an American." -- Charles Foster Kane "WAKE UP AMERICA; WAKE UP!" Those words, spoken by John Lewis just before he ended his speech at the 1963 March on Washington, are as imperative today as they were 53 years ago. During this Labor Day week, the traditional start date for fall presidential campaigns, the time is overdue for all Americans to wak...

Throwing Bodies at the Problem

"Nine women can't make a baby in one month." That's good because adding headcount is not nearly as productive as it appears at first glance. Last post , I wrote about Baumol's cost disease and why labor in stagnant sectors (like law) gets more expensive over time. This post, I'm going to use  Brooks' law  as a starting point to discuss the fact that labor gets less productive the more of it you have. The most cited 'law' in technology is Moore's law . In the popular consciousness, Moore's law ...
