New very relatable #meme by the amazing @raj-physics.bsky.social #physics #STEM
Meme. Woman is showing stack of paper to cat asking "You checked the paper before you submitted it?", cat replies "Yes". Woman asks "Then why does it say 'Tailor expansion?'". Zoom in on cat staring at the paper with wide eyes. The pun is that 'tailor' is spelled like tailor the dress maker, but in physics, Taylor expansion is spelled with a y.

The new gravitational wave data is public, this is so exciting! Analyzing so many events is becoming increasingly expensive. That's why we have used DINGO for the first time to support the official LVK analysis. After training the neural networks, you can analyze suitable events over night! 🥳🤩

The original brains of computer science were women. Once people started realizing the potential of computers, their contributions were downplayed, their expertise questioned, and their results presented by men. What we see here are the consequences of purposeful discrimination against women...so sad

Out now in @natphys.nature.com "The undervaluing of elite women in physics", with @weihuali.bsky.social and H Zheng, we show how election into prestigious academic societies has markedly different effects on the research prominence of women and men physicists /1 www.nature.com/articles/s41...
Screenshot of the top of the paper "The undervaluing of elite women in physics",
Abstract: "Elite women in physics wait longer than
men for recognition. Once elected to the US National Academy of Sciences, however, their prominence surges — evidence that their work was undervalued all along."
Body: "Physics has changed dramatically over the past 50 years, both in the range of phenomena it studies and its demographic composition. For example, the share of publishing women physicists worldwide has more than doubled — from 4.5% in 1970 to 9.2% in 2020 — and continues to increase. Yet parity remains distant, raising the question: to what degree has the physics community progressed toward the meritocratic ideal of recognizing scientists purely on the basis of their contributions?

We address this question in two ways. First, we compare broad trends in the productivity and prominence of men and women physi- cists worldwide over the past 50 years. Second, we examine the careers of elite physicists, asking whether the high honour of being elected to the US National Academy of Sciences (NAS) impacts the careers of men and women in physics differently. Our analysis leverages a recently developed Bayesian network model1 to estimate individual measures of scientific productivity and prominence from large-scale bibliographic data. We apply this model to a global physics collaboration network constructed from first- and last-author pairs in 9.1 million physics journal articles (omitting single-author papers) published between 1950 and 2023 and recorded in the OpenAlex bibliographic database. Within this global network, we focus on 93,456 established physicists with at least 30 years between their first and most recent publication and with at least 10 first- or last-author publications..."

Dear Physicists and Physics fans, I would like to encourage you to celebrate #WomenInPhysics Day this Friday, November 7th. Why November 7th? Because it is the birthday of two of the most impactful women physicists of the 1900's: Marie Curie and Lise Meitner. 🎢 ⚛️ 🧪 👩‍🔬
WOMEN IN PHYSICS DAY! 

In honor of the pioneering women in physics who broke down barriers to do what they love, we celebrate Women in Physics Day on November 7th, the birthdate of both Marie Curie and Lise Meitner.

Marie Skrodowska-Curie (1867-1934)

Radioactivity pioneer, two-time Nobel laureate 

A giant of science, Marie Sktodowska-Curie conducted pioneering research on radioactivity, a term she coined. She discovered two elements, founded two medical research centres, won two Nobels, and invented mobile X-ray units (dubbed petites Curies), saving countless lives in World War 

Lise Meitner (1878-1968) Nuclear physicist

When Lise Meitner was a teen, Austria restricted female higher education. She pursued physics anyway, and 25 years later became the first woman in Germany to hold a professorship in physics. She helped discover nuclear fission, but was contentiously not awarded the 1944 Nobel alongside collaborator Otto Hahn.

Why are there two LIGO observatories? LIGO has two detectors ~3000 km apart for three main reasons: 🎧 Noise discrimination ⏰ Signal timing 🗺️ Source localization Find out more www.ligo.caltech.edu/page/ligo-de... Graphic by Mayara Pacheco 🔭🧪
An infographic titled "Why are there two LIGO observatories?" features a map of the United States showing two LIGO locations separated by 3000 km. Three key reasons are illustrated on the right: Noise Discrimination: Each detector is sensitive to local ground vibrations. If both were close together, they’d pick up the same environmental noise, making it difficult to distinguish true gravitational waves. By comparing data from distant locations, LIGO can filter out local noise and isolate real gravitational wave signals.
Signal Timing: Gravitational waves travel at the speed of light, so any signal detected at both sites with a time difference of over 10 milliseconds can be ruled out as a real wave. This time-based filtering helps validate detections.
Source Localization: With two detectors, LIGO can begin to narrow down the area in the sky where a wave originated. Adding more detectors (like Virgo in Italy) greatly improves localization. This was crucial during the 2017 detection of a neutron star collision, where combined data allowed astronomers to quickly identify the galaxy that emitted both gravitational and electromagnetic signals, leading to the most observed astronomical event in history.
