Happy 120th birthday, special relativity!

Albert Einstein introduced special relativity in the paper "On The Electrodynamics Of Moving Bodies," published in Annalen der Physik #OTD in 1905. 🧪 ⚛️ 🔭

Manuscript: onlinelibrary.wiley.com/doi/abs/10.1...
English: www.fourmilab.ch/etexts/einst...
A black and white photo of Albert Einstein, around age 25, sitting at a desk. He is a wearing a flannel suit and resting his right arm on the desk. Einstein is looking to the left of the photographer in this posed photo. The first paragraph of the paper, in German. Translated to English is reads: It is known that Maxwell's electrodynamics—as usually understood at the present time—when applied to moving bodies, leads to asymmetries which do not appear to be inherent in the phenomena. Take, for example, the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet, whereas the customary view draws a sharp distinction between the two cases in which either the one or the other of these bodies is in motion. For if the magnet is in motion and the conductor at rest, there arises in the neighbourhood of the magnet an electric field with a certain definite energy, producing a current at the places where parts of the conductor are situated. But if the magnet is stationary and the conductor in motion, no electric field arises in the neighbourhood of the magnet...

LEFT: Where our government incarcerates a person who has a tattoo in honor of a family member.

RIGHT: Where our government incarcerates a person who has facilitated and/or engaged in the sexual assault of over a thousand children.

RFK Jr. is very loud and very WRONG about Autism.

1. It’s not a disease
2. There are thousands of people with Autism Spectrum Disorder who pay taxes, have jobs, can use the bathroom on their own, and are thriving in life.

I see it. I have lived it. 83 years ago, the U.S. government turned upon a group of its own citizens and residents and sent them to internment camps without due process. I was there among them. American fascism is back. It is here. It is now.
A tweet by Sarah Longwell (@SarahLongwell25 ) reads: "He’s threatening media companies who are critical of him. He’s talking about sending Americans to foreign prisons. He’s signing executive orders to investigate former staff members who spoke out against him. Don’t you see what’s happening here?"

They’re going to keep pushing until something stops them.

This is what the government did with 120K+ Japanese Americans in 1942.

I know. I was there in those camps.

The Man Who Bought the World

Trump claimed all would be hunky dory if we empowered him and space oddity starman Elon Musk. But after stacking his cabinet with scary monsters and super creeps, he's become Aladdin sane about buying Greenland and Panama. Next will be China, girl.
