Particle physicist. Flip spends his time thinking about dark matter while covered in chalk dust. https://particle.ucr.edu

Here's an application of birdtrack notation to prove a curvature tensor identity. It is identical to index notation, but I find the diagrammatic proof easier to follow once I picked up the rules. This is a solution to exercise [14.10] in Penrose's Road to Reality.

This month and next month our Phy-Sci Book club is reading a couple of books ahead of Earth Day. Next week we're discussing Rachel Carson's classic, Silent Spring. The book continues to hold its own as remarkable feat of accessible science writing 63 years after its original publication.

The last few generations of particle physicists, especially those on the model-building side, have learned field theory without an emphasis on the analytic properties of scattering. Sebastian Mizera's lecture notes an excellent resource: arxiv.org/abs/2306.05395

Physics of the Analytic S-Matrix

You might've heard about various mathematical properties of scattering amplitudes such as analyticity, sheets, branch cuts, discontinuities, etc. What does it all mean? In these lectures, we'll take a...

One of my favorite publications, the American Journal of Physics, has an open access resource letter on dark matter. It's a great place to get started when looking to navigate the review literature in the field. pubs.aip.org/aapt/ajp/art...

Resource Letter DM1: Dark matter: An overview of theory and experiment

Editor's Note: One of the most interesting mysteries of physics is that of the invisible matter in the universe. This so-called dark matter makes up a larg
