Vor ziemlich genau 8 Jahren hat Jörg Meuthen, ehem. Vorsitzender der AfD, gesagt, er sehe in den Innenstädten "noch vereinzelt Deutsche". Die Vorsitzende der CDU, Angela Merkel, hat ihm umgehend widersprochen. Friedrich Merz hat heute die Sprache und Position der AfD übernommen.

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge? It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

Are you a student or early-career researcher in quantum computing or quantum information? Then the following is for you. We're organising a focused, community-driven conference at Leibniz Universität Hannover, hosted by Prof. Robert Raussendorf. 🗓️ Save the date: August 27–29, 2025

Nature study: when do girls fall behind in #maths? During their 1st year at primary school. 4 yr study, 2.6M French children. By comparing kids born a month apart but in diff school years they show it's education, not age, that triggers the gap☹️ 🧪👩‍🔬 ℹ️: www.nature.com/articles/s41... 👇Excellent 🧵

A set of graphs

Title:  WATCH THE MATHEMATICS GENDER GAP EMERGE The school environment triggers a gender gap in mathematics. Test results
from all children in France who started school in 2018 reveal the trend.

Graph 1: Start of first year of school.  Boys and girls show similar performance in maths test results.

Graph 2:  Four months into first year
We see more boys are now starting to achieve the higher grades with girls getting more poorer grades

Graph 3:  Start of second year at school
Gender gap is now exaggerated with boys twice as likely to get the top marks than their female counterparts.

I don't post super often here, but I just came by to share this news article with you (published alongside the paper in Nature yesterday). www.nature.com/articles/d41... There are a couple of sentences in the news article that stuck with me more than anything: 1/x

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back. This was the largest political gathering in Denver since Obama in 2008. Also bigger than the 2024 DNC. And the largest ever rally in Bernie’s career (and obviously, mine too).

A team led by physicist Chien-Shiung Wu obtained the first experimental confirmation of “parity violation,” in the decay of Cobalt-60, #OTD in 1956. Her theory colleagues received a Nobel for the prediction, but she was left off the prize. 🧪 ⚛️ 👩‍🔬 Image: Smithsonian Institution Archives

In 1994 when I worked at Kitt Peak National Observatory, @todlauer.bsky.social made an off-hand comment about grape plasma in the microwave. Being an experimental physicist (read as “nerd”) I immediately tried it during night lunch. Who knew it was come to this? 🧪🔭⚛️

Grapes double sensor magnetic power in an epic quantum breakthrough

Grape pairs boost quantum sensor performance by enhancing magnetic fields, aiding compact and cost-effective sensor development.
