Richard Feynman Quantum Electrodynamics Lecture at University of Auckland (1979) mentions it several times.

This was one of the first two great successes of quantum electrodynamics, the other one being the Lamb shift.

In youtu.be/UKbp85zpdcY?t=52 from freeman Dyson Web of Stories interview (1998) Dyson mentions that the original key experiment was from Kusch and Foley from Columbia University, and that in 1948, Julian Schwinger reached the correct value from his calculations.

Apparently first published at The Magnetic Moment of the Electron by Kusch and Foley (1948).

"Quantity" refers to a measurable property or attribute of an object or phenomenon that can be expressed numerically. It indicates how much of something exists and can apply to a wide range of subjects, including physical objects, time, volume, weight, distance, and more. In mathematics and science, quantities can often be classified as: 1. **Scalar Quantities**: These are quantities that have magnitude only and no direction. Examples include temperature, mass, and speed.

Olog is a term that can refer to several different concepts depending on the context. Here are a few possible interpretations: 1. **Olog (Ology)**: In a more informal or humorous sense, "olog" is often used as a suffix to create playful names for various fields of study (like "biolog" for biology, "geolog" for geology, etc.), especially in discussions of pseudo-disciplines or in casual contexts.

The "magic angle" is a term used primarily in the context of nuclear magnetic resonance (NMR) spectroscopy and solid-state NMR. It refers to a specific angle, approximately 54.74 degrees (or arccos(1/√3)), at which the anisotropic interactions in a solid sample can be effectively averaged out. This is particularly relevant for studying solid materials where the molecular orientations can lead to broadening of NMR signals.

Limited the number of articles, and the size of article bodies. This, together with the reCAPTCHA setup from Email verification and reCAPTCHA signup protection should prevent the most basic types of denial-of-service attacks by filling up our database.

The limits can be increased by admin users from the web UI, and will be done generously when it is evident that it is not a DoS attack. Admin users are also a recently added feature.

Added this basic but fundamental protection layer to the website.

The email setup will of course be reused when notifications are eventually implemented.

Currently using SendGrid as the email provider. Very easy to setup, and has a free plan.

Adding reCAPTCHA immediately after email is a must otherwise an attacker could send infinitely many emails to random addresses, which would lead to the domain being marked as spam. I was pleasantly surprised about how easy the integration ended up being.

A different and more elegant way to express Maxwell's equations by using the:instead of the:

Subtle is the Lord by Abraham Pais (1982) chapter III "Relativity, the special theory" mentions that this fact and its importance (we want the laws of physics to look the same on all inertial frames, AKA Lorentz covariance) was first fully relized by poincaré in 1905.

And at that same time poincaré also immediately started to think about the other fundamental force then known: gravity, and off the bat realized that gravitational waves must exist. general relativities is probably just "the simplest way to make gravity Lorentz covariant".
