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...

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. 🧪 ⚛️ 🔭

Only an administration intent on committing war crimes in the present and future would stoop to calling Wounded Knee a "battle" rather than what it truly was: a massacre of over 250 Lakotas, mainly women, children, and the elderly. 1/

When Violence Breaks, the Vulnerable Bleed First Sarah McBride voted to condemn the assassination of Charlie Kirk. I would have too.

Charlie Kirk dehumanized trans people as “a throbbing middle finger to God.” That cruelty was infuriating. But Sarah McBride was right to condemn his assassination — political violence will not liberate trans people, it hurts us most. aridrennen.substack.com/p/when-viole...

Pretty clear that some places are just using current events as an excuse to get rid of people they weren't comfortable having around anyway. Darkness is coming, democracy is dying.

Pay attention. Something dark might be coming.

The murder of Charlie Kirk could have united Americans to confront political violence. Instead, Trump and his anti-democratic radicals look to be readying a campaign to destroy dissent.

We're witnessing the most aggressive, fanatical crackdown on free speech in my lifetime. The speed and breadth of government censorship and private sector and nonprofit capitulation has been astonishing. As has the lack of urgency/silence from people who've long claimed to care about this stuff.

This is literally true, and I'm very worried about the implications of it. Even among what I consider to be relatively levelheaded associates (in non-political spheres), the conservatives are almost all Trumpers. The future of the GOP only gets Trumpier.

Not to put too fine a point on it, but when the Nazis first started sending Jews and other victims to camps, they called it deportation, and the camps were technically in other countries.

NEW 🧵 Is human intelligence starting to decline?

Recent results from major international tests show that the average person’s capacity to process information, use reasoning and solve novel problems has been falling since around the mid 2010s

What should we make of this?

You may not care, but I do. Is Trumpism driving a generation to leave this country? My daughter will study abroad next year and is already researching where to live and work internationally after graduation because of Trump.

Same with some of her classmates. It breaks our hearts, but I get it.

Loss of Civil Rights for millions of Americans is inconsequential according to the New York Times.

There is no other American institution that has contributed more towards the erasure and systemic elimination of transgender people except maybe the heritage foundation.
