Day 54

[reading: Michael Peskin & Daniel Schroeder, "An Introduction to Quantum Field Theory"]

I noticed a "123 meme" on a couple of blogs recently. Is it just me, or do these meme things really highlight the whole echo-chamber, nothing-of-interest-to-write-about nature of many blogs? (Pot, kettle, black). Or maybe that's just rampant cynicism (who, me?).

(Oh, and in my case the 123 thing is annoyingly difficult to do, given the status of Mac OS X MathML. An ugly version is: 'To do this, we replace the scalar particle φ with a vector particle Aμ and replace the Yukawa interation Hamiltonian with
Hint = ∫ d3x e ψ γ μ ψ A μ ').
