In November 2026, a historic milestone awaits humanity's Voyager 1. The legendary probe will reach the "one light-day" mark, meaning it will be so distant that communication requires a 48-hour round trip!

Great news! While Trump is busy dismantling the Library of Congress, the German National Library of Science and Technology (@tibhannover) is preparing for more to come: they've downloaded the entire 10 TB of the arXiv preprint server and safeguarded more than 2.6 million scientific articles. Thank you so much! This was especially needed since, last year, the arXiv decided to shut down its mirror network.

Forschung und Wissenschaft sind international, nicht umsonst spricht man von internationalen Fachcommunities.Micky Lindlar (TIB – Leibniz-Informationszentrum Technik und Naturwissenschaften und Universitätsbibliothek)
J. J. Thomson, who was born #OTD in 1856, received the Nobel Prize in Physics in 1906 for his discovery of the electron, the first subatomic particle to be found.
Thomson was also a teacher, and seven of his students went on to win Nobel Prizes: Ernest Rutherford, Lawrence Bragg, Charles Barkla, Francis Aston, Charles Thomson Rees Wilson, Owen Richardson and Edward Victor Appleton.

Does anyone know of an OA thermodynamics book that would be suitable for a one-semester, early undergrad course on the subject? Something comparable in scope/level to, e.g., Finn's Thermal Physics: thermodynamic potentials, magnetic work, at least some calculation of microcanonical and canonical probabilities, etc.
This textbook seems OK for what it does cover, but it doesn't go far enough:

And David Tong's lecture notes presume that the students have already had the kind of class I'm thinking about:

What is there in the middle?

... Another "does this book exist" question: Is there an OA textbook suitable for a one-semester course on special relativity? Again, OpenStax provides an example that seems fine as far as it goes but that only goes partway:

What covers Minkowski spacetime, the energy-momentum relation, maybe a little about how "force" works in SR... Is there an open-access equivalent to Anthony French's text from back in the day when I was young?

Kicking Erwin Schrödinger out of my idols. Not because he chose a cat for his thought experiment, but because of one thing I learnt: he sexually abused children and kept a diary about it. 🤮 Src: en.wikipedia.org/wiki/Erwin_Sc…

I made a post on my (rarely used) blog thinking about my pursuit of higher mathematics and about how/where to apply for grad schools. I would love some advice from those who have pursued their love for Mathematics and it's application in other fields in grad school! I have some concerns and I feel very stuck.

I have been wanting to apply for grad school for a long time, but as the mathematically obsessed person I am feels frozen trying to find direction and suitable programs to apply to.Frederick Morlock
