We just published a new paper about a totally new method to compute neutron scattering. The problem is deceptively simple: what happens when you throw a neutron against an atomic nucleus? If we throw many neutrons, how many will bounce off without exchanging […] [Original post on mathstodon.xyz]

Hello! Do you have access to an x-ray system, CT, Radiography, or a few seconds on the LHC main beam with a homebrew pixel detector? Do you want to take part in #xraymyadvent this year? You know you do.

If you’re a user of Libby (the library app), consider before following their suggestion to type #inspireme into the search bar. It seems harmless, but it turns on an unrequested AI feature, & there is no way to reverse that. This comes courtesy of ProfHeyRochelle, who is now reasonably pissed […]

Quite surprisingly, most of the properties of (classical) synchrotron radiation were worked out by G.A. Schott in1907--1912 in his dissertation work. Working in a 'pre-quantum' world, Schott wanted to explain the observed lines in the emission #spectra of atoms […] [Original post on aus.social]

Synchrotron light is conventionally defined as the emission from accelerated ultra-relativistic electric charges. Ultra-relativistic means that the speed of the charge is extremely close to the speed of light, v ≈ c. The first part of the book deals with introductory concepts, starting from […]

In a bit of shameless self-promotion, I'm proud to announce that I've a new book out! "Synchrotron Light: a Physics Journey from Laboratory to Cosmos", was written together with my co-author Prof. David Paganin and published by Oxford University Press. Target […] [Original post on aus.social]

Non scrivo molto in italiano (in realta' non scrivo molto in generale 🫠 ) ma devo fare un'eccezione per questo libro divulgativo di fisica quantistica scritto a quattro mani da Anna Parisis e Valentina Schettini. Il libro s'intitola "Quanti Quanti" edito da Salani. E' stata una lettura molto […]

Wanting to live in the end times is kind of cowardly since it absolves of you of the burden of building a better future. Some great compelling force will come down from on hight and sort it all out. Since you don't really know what times you face it's more responsible and brave to live as if […]

I'm looking for a #developer to join our team at Rubens Technologies on a part time basis. Rubens is a fruit quality assessment technology based on spectrometry and machine learning/chemometrics. Primary responsibility will be to automate current workflows and progressively step in to […]

🚨 It’s official! The Journal of Open Source Software has published our data analysis software for terahertz time-domain spectroscopy! 🍾🎉🌈 Congrats to my student-researcher coauthors! Thanks also to the people at @pyOpenSci, who organized the peer review and helped during development. From […]

For those of you who weren't at #monktoberfest last month, here's my talk about how people with no stake in the game taught Open Source users to be assholes and maintainers to not know how or who to ask for help, with almost predictably disastrous consequences […]

Americans: "Oh no, we couldn't _possibly_ replace Andrew Jackson with Harriet Tubman on the $20; what kind of precedent would it set if we just started changing the picture on our money?" Australians:
