Generally means that he form of the equation $f(x)$ does not change if we transform $x$.

This is generally what we want from the laws of physics.

E.g. a Galilean transformation generally changes the exact values of coordinates, but not the form of the laws of physics themselves.

Lorentz covariance is the main context under which the word "covariant" appears, because we really don't want the form of the equations to change under Lorentz transforms, and "covariance" is often used as a synonym of "Lorentz covariance".

TODO some sources distinguish "invariant" from "covariant": invariant vs covariant.

A random field you add to make something transform locally the way you want. See e.g.: Video "Deriving the qED Lagrangian by Dietterich Labs (2018)".

This was the Holy Grail as of 2023, when text-to-image started to really take off, but text-to-video was miles behind.

They scanned a bunch of books, and then allowed search results to hit them. They then only show a small context around the hit to avoid copyright infringement.

www.aip.org/history-programs/niels-bohr-library/ex-libris-universum/harvard-project-physics-role-history-science mentions that they have a special focus to the history of physics, as can be seen e.g. on The World Of Enrico Fermi by Harvard Project Physics (1970).

MOre precisely we of course mean the first non-Coinbase transaction obviously.

Google has put considerable effort into custom hardware to greatly optimize its stack, in a way that is quite notable compared to other tech companies.

Their UI is horrendous as of 2020:

They removed referrer path completely in GA4... OMG WTF are they doing!
