In Oxford and love astronomy? Join me on Oct 29th, as I speak with @chrislintott.bsky.social about celestial bodies and citizen science.
All part of Hevelius Days in the @bodleian.ox.ac.uk. Free event, but booking is essential: visit.bodleian.ox.ac.uk/event/oct25/...

🧪🔭
From Sextants to Machine Learning: The Hunt for Planets and Galaxies 29 October 12.30–2pm Weston Library, Oxford Admission FREE. Booking essential. Discover how science, curiosity and collaboration shape our understanding of the universe. Astronomer Professor Chris Lintott and zoologist Dr Joanna Bagniewska explore how discoveries are made from Johannes Hevelius’s Selenographia (1647), one of the first lunar atlases, to today’s citizen science projects on platforms like Zooniverse. Why are some constellations “obsolete”? Could anyone find a new planet? And what does global collaboration in science look like in an age of politics and misinformation? Part of IF Oxford: Festival of Science and Ideas

Theoretical transmission spectrum for a Rb atomic vapor cell of natural abundance on the D2 line, which is subject to horizontal-linear light as a function of linear detuning. The figure shows the transmission spectrum and at 12 discrete detuning values the polarization states of the two propagation eigenmodes. Differences between the old and new theory are seen only over a limited range of frequencies. The experimental spectrum shows excellent agreement with the new theory. Experimental transmission spectroscopy of a natural abundance Rb vapor cell of length 2mm as a function of linear detuning. There is a 2 by 2 array of sub panels showing 4 transmission spectra for different incident linear polarization angles. Theoretical transmission spectru for a Rb atomic vapor cell of natural abundance on the D line, which is subject to vertical-linear light as a function of linear detuning. Polarisation eigenmodes are shown at 14 discrete frequencies. Differences between the old and new theory are seen over a broad range of frequencies. The experimental spectrum shows excellent agreement with the new theory.

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.
Experimentology cover: title and curves for distributions.

🧪⚛️ There is a serious disagreement btw experiment and theory in understanding the ionization energy of a particularly excited state of helium. This is one to watch, though caution is always advised, as anomalies like this historically tend to go away. nanoscale.blogspot.com/2025/06/a-pr...

Anyone involved in publishing, reading, writing or editing scientific papers should read this argument against generative AI carefully.

A close reading of the "AI" fake cases judgment

Why it the very plausibility of AI-generated case law that should put lawyers on their guard
