Explain it in 60 Seconds: Lattice QCD. Really!

I am afraid this otherwise commendable effort by this Fermilab/SLAC/US Department of Energy publication failed! Disappointing!

This article is very basic and superficial! The article is also extremely short like a tabloid article. The author does not even bother to cite the referenced article properly!

"... In the 1970s, physicist Kenneth Wilson was studying crystalline structures when he had an idea: What if physicists reimagined quarks as atoms in a crystal? Wilson took the traditional grid system used for crystals and—to make it work with quantum mechanics—added “imaginary time,” a concept analogous to imaginary numbers, as a fourth dimension. He then reduced the quarks to their fundamental characteristics, written out as quantum numbers, and placed these quantum numbers on his 4-D grid.

In 1974, he published his new calculation method, called lattice gauge theory, or lattice QCD, and the idea took off. ..."
