In today's AIP History Weekly Edition, we sifted through the mammoth program for the ESHS/HSS meeting in Edinburgh next week to highlight talks related to the history of the modern physical sciences. It's a lot, and there was much we didn't cover. Full program here: hssonline.org/page/Edinbur...

Die Wissenschaft in Deutschland ist leistungsstark, international vernetzt und ein zentraler Motor für Innovation und gesellschaftlichen Fortschritt. Die wissenschaftspolitischen Positionen der AfD für die Landtagswahlen in Sachsen-Anhalt erwähnen dies allerdings nicht. 1/7
»Die Wissenschaft ist gefordert, der Untergangserzählung der AfD ein realistisches Bild entgegenzusetzen und zu zeigen, was sie tut und verändern will, um weiterhin Treiber für Innovationen und Wohlstand zu sein.«

Relativity for Retired Engineers by David Garfinkle arxiv.org/abs/2605.21660 "Scarcely a month goes by when I don’t receive an email, phone call, or manuscript from someone, more often than not a retired engineer, who has their own theory of relativity." — Since ChatGPT: scarcely a day goes by!

Relativity for Retired Engineers
We provide some guidance and examples to clear up common misconceptions about special relativity. These misconceptions often come from trying to express the truths of special relativity in Newtonian t...

A forgotten theory of quantum gravity: Suraj N. Gupta and his quantization of general relativity - The European Physical Journal H
Gupta was among the first to attempt the quantization of Einstein’s nonlinear theory of gravity. He had an independent program to quantize gravity in a manner akin to electromagnetism, which spanned at least two decades. He adopted the flat-space views of Rosen and Papapetrou and built his theory around these ideas. Although he was well known for his work in quantum electrodynamics, little is known about his work in quantum gravity. For that reason, in this paper, we try to present a historical overview of his research program.

Wer schreibt jetzt die positive (nicht utopische) Zukunftsvision eines Europas, das sich in Elektrifizierung, Verteidigung, Humanismus und menschenwürdiger Migration so einig ist, dass es langfristig das attraktivste und stabilste Gesellschafts- und Wirtschaftsmodell bietet und deshalb prosperiert?
