His family made their fortune off quinoa and other ancient grains.
(None of that is true, but neither is the stuff in his tweet.)
If I were Greg Abbot I would simply make stuff up to distract my constituents from the fact that I let Covid run wild across the state and also let my corrupt buddies dismantle the power grid.

Albert Einstein, age 26, submitted his paper "Concerning an Heuristic Point of View Toward the Emission and Transformation of Light" to Annalen der Physik #OTD in 1905. It explained the photoelectric effect and established the reality of quanta. onlinelibrary.wiley.com/doi/abs/10.100…
This is the first paper from Einstein’s “Miraculous Year,” when he explained the photoelectric effect, Brownian motion, and special relativity. It was the work on the photoelectric effect that was singled out sixteen years later in his Nobel citation.
Here is a thread on the motivation for Einstein’s paper, his claims about the nature of light, and how a famous physicist who was sure Einstein was wrong ended up providing the strongest evidence in support of his hypothesis.
Mathematician Grace Chisolm Young, author or co-author of a host of articles and books on set theory, geometry, topology, and calculus, and the first woman to officially earn a doctoral degree from the University of Göttingen, was born #OTD in 1868.

It’s hard to say exactly how many papers and books she produced. She wrote several articles on her own, more as co-author with her husband William, and also worked on many projects where William appeared as sole author. It’s estimated they wrote over 200 papers & books together.
Grace Chisholm Young is best known for her contribution to what is now called the Denjoy-Young-Saks theorem, classifying the possible behavior of the Dini derivatives of arbitrary measureable functions.

The NYT was happy to publish an op-ed by Senator Josh Hawley, an honest-to-God fascist who supported a failed violent insurrection against the US government. But God forbid someone say they had “chills” seeing the inauguration that insurrection failed to prevent.
The fact that the @nytimes sided with the the folks stalking and threatening @wolfe321 is grotesque. They should re-hire her.
This is gamergate-style fake outrage and the @nytimes, by happily giving in, has announced that it’s a winning strategy. The folks behind it are thrilled and will use it on every reporter and staff member they can. Absolutely pathetic.
The physicist Hideki Yukawa was born #OTD in 1907. In 1934 he predicted the existence of a boson with a mass approximately 200 times that of the electron, based on the range of the strong nuclear force between protons and neutrons in the nucleus.

Yukawa knew that these particles must be massive, so that they would typically decay over a distance comparable to the range of the strong nuclear force. As a result, they generate an attractive potential that varies with distance r as exp(-λr)/r.
It’s like the 1/r Coulomb potential associated with the exchange of massless bosons (photons), with the exponential factor accounting for the fact that the particles responsible for the force don’t make it very far before decaying
