Sidney Drell: 1926-2016

The New York Times brought us poor tidings yesterday. Sidney Drell died at dwelling household inwards Palo Alto (the town approximately Stanford) on Wednesday, Dec 21st, at historic menstruation of 90.3.

The data was confirmed past times his miss Persis Drell, also a particle physicist as well as lately the manager of SLAC (Sidney Drell has exclusively been a deputy manager of SLAC inwards his life). One to a greater extent than miss as well as i boy survived him, along alongside iii grandkids.



I am former plenty to retrieve his scream primarily for the Bjorken-Drell textbook of quantum patch theory. They wrote mostly minus convention for the metric has also been known equally the Bjorken-Drell convention. That's a trend to nation that they basically defined the mainstream inwards particle physics.

Note that the kickoff edition of Peskin-Schroeder appeared inwards Oct 1995, to a greater extent than than 5 years after I started to written report QFT, as well as therefore it's clear that I had to live led to an older text similar Bjorken-Drell.

I retrieve that I was intrigued past times the watch that the Bjorken-Drell textbook actually explained everything I needed to fully depict both wave-like as well as particle-like properties of the electromagnetic field. But it took me some fourth dimension to meet through all the equations that looked complicated – to figure out that the quantum patch alongside the "same" Hamiltonian that nosotros know equally the amount liberate energy of the patch inwards classical electrodynamics is rewritten equally a higher-dimensional harmonic oscillator which may live quantized into photons. This betoken is actually as well as therefore uncomplicated as well as the mass made it await as well as therefore difficult (when I was virtually 16) as well as therefore I tend to mean value that books convey gotten to a greater extent than pedagogically edible.

Although it was my kickoff QFT textbook I studied, I switched to other books, similar Ramond's, rather early on as well as therefore I don't fifty-fifty retrieve whether Bjorken-Drell included a systematic handling of the Feynman diagrams (my guess would live No). But I am certain that the potent as well as weak interactions are covered inwards a trend that is hopelessly outdated today.




But the books alongside Bjorken (a fundamental guy behind our agreement of the deep inelastic scattering) are really far from Drell's exclusively achievements, of course. His scream is oft used inwards the Drell-Yan process, the annihilation of a quark-antiquark distich from 2 hadrons to a lepton-antilepton distich through a neutral intermediate boson (Z or photon).




Sidney Drell was born inwards 1926 inwards Atlantic City, New Jersey, to Russian Federation Jewish emigrants (dad was a chemist as well as woman raise was a teacher). He got his degrees from Princeton (where he was admitted at historic menstruation of 16) as well as University of Illinois as well as rapidly began to locomote for the U.S.A. government. He defended nuclear deterrence. These days, Donald Trump as well as Vladimir Putin announced that they desire to revive nuclear arms races which must live a lot of fun as well as that's what Drell was defending during the mutual frigidity war, too. H5N1 superpower must live able to demo its muscles. He was an of import policymaker nether Johnson as well as Nixon (so he was bipartisan, equally y'all tin strength out see) as well as a shadow adviser to Kissinger.

(Fred Singer is telling me that he, Fred, taught Drell equally the instructor of a lab course of pedagogy when Drell was a senior at Princeton. Drell sometimes joked that it was this lab course of pedagogy that decided that Drell had to larn a theorist. C.S.Wu supervised those courses simply she wasn't a professor due to her beingness she. She was lucky to live allowed inwards – women were somewhat reasonably considered distractions past times Princeton upward to the 1950s as well as couldn't easily locomote into the physics building.)

However, later, Drell would denounce Reagan's Star Wars as well as he also led the efforts to trim back the nuclear weapons, equally agreed past times Reagan as well as Gorbachev (I guess that y'all must convey heard some of the politicians' names that surrounded Drell all the time), as well as fifty-fifty to a greater extent than recently, he reasonably argued (like others) that Islamic terrorists don't attention virtually their devastation as well as therefore deterrence no longer plant as well as the nuclear weapons are useless inwards that context.

Google Scholar offers 1450 papers alongside the scream "Sidney Drell", starting from the books cited 5,000 as well as 3,000 times, as well as some 5 papers unremarkably alongside Yan alongside 500-1,000 citations. Basically all his papers may live considered applications of quantum electrodynamics (QED) or aspects of QCD as well as lattice QCD where he focused on the electromagnetic business office of the interactions, too.

Sidney Drell has been a fellow member of NAS, AAAS, won the Fermi accolade inwards 2000, the National Medal of Science from Obama inwards 2013 (picture at the top).

R.I.P., Prof Drell.
