You have the inequality backwards!

Careful; you need to apply L'Hopital's rule.

I do the puzzle every day. I've been collecting clues that have caused me trouble, a wrong answer. I hope someday to be able to construct such a puzzle with one set of clues and two complete but incompatible solutions. A thesaurus wi

You might be thinking of the image of M87 from a few years ago. M87 is in a different galaxy. This image is of Sag A*, the black hole at the center of the Milky Way.

I'll simply have to disagree. The LQCD calculation of gA, for example, provides the tightest constraint on new right-handed currents beyond the Standard Model. The issue, of course, is that without a calculation the "new physics

I think your comment is far behind the times. Directly from QCD we have: computed the low-lying parts of hadronic spectrum, computed the proton-neutron mass splitting, made _pre_dictions about hadronic masses that were then found at the LH

We know why SM particles come in "whole generations": a mathematical consistency condition known as anomaly cancellation [0]. We also know that with only 2 generations we cannot get violation of charge-parity symmetry [1] via the

The Higgs is like the water in the ocean. Particles are like boats. Some boats have sleek hulls and so the water doesn't slow them down too much. These are particles without much mass. Some boats have a few barnacles on their hulls.

On of the (self-admitted) flaws in Newton's conception of gravity is that it's in terms of forces (or potentials) that act across large distances; it's part of his "hypotheses non fingo". One of the philosophically

It's true that a mathematically rigorous proof that... well... any QFT exists at all escapes us for all but extremely special cases. But, given you've given a whole spiel about about EFTs, you can think of the lattice formulation
