‘Impossible to explain’ math proof

Wikimedia Commons
Mathematicians proved a decades-old conjecture that two major areas of math were profoundly linked, and apparently it’s very important.
The 1967 “Langlands conjecture” proposed that
number theory and harmonic analysis are interchangeable. If true, it would amount to a “grand unified theory” of math. A new 1,000-page proof shows it to be true, or so we are informed: The concept is so complex that it is “
impossible to explain the significance … to non-mathematicians,” one mathematician told New Scientist. Often, in science, showing that two theories are symmetrical — such as electricity and magnetism — leads to breakthroughs. Perhaps that will happen here, or perhaps it is just a beautiful thing, opaque to those of us without the skills to see it.
