When I asked a professor if he shared these concerns, he waived them away and said he didn’t care where the money came from as long as it led to good science. I remained skeptical, but as I went on I could see what he meant: the US government has supported a lot of good science without a lot of strings attached, so long as the research was aligned with broad strategic priorities. That quid pro quo helped build American science throughout the Cold War, but science was always vulnerable to government interference.<br/><br/>I hear that this book by Naomi Oreskes describes a similar dynamic in oceanography.<br/><br/><a href="https://press.uchicago.edu/ucp/books/book/chicago/S/bo59258933.html">https://press.uchicago.edu/ucp/books/book/chicago/S/bo59258933.html</a> 2025-04-19T06:49:11Z https://yabu.me/nevent1qqs90kqnkekd8780aurpwzs70dy5w9a3gfl3a6csqy667ukpcfgl22gzyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08cl6ycca This is a nice summary of the historical developments that made universities in the US so vulnerable to the current attack.

The society leadership seems to be pretty active in doing what it can to counter US Executive actions that harm members, including filing amicus briefs in court cases. They say they are not changing their messaging or their programs, which include several that are designed to underrepresented groups in physics.<br/><br/>The audience questions and comments were pushing them to do more, though, and at times the leadership seemed a bit defensive. I had the impression they felt they were already doing better than their peer academic societies and were working overtime to keep it that way. LGBTQ+ members were visibly agitated, for obvious reasons, and lobbying for more official action on their behalf.<br/><br/>Several senior members, including French Nobel Laureate Serge Haroche, urged them to think outside their disciplinary box and engage with civil society more broadly, on behalf of scientific values. There was a palpable sense that people were seeking solidarity.<br/><br/>I also heard lots of stories of how people’s lives were being disrupted at critical moments in their lives and careers; some were losing funding, others were losing their jobs, and everyone was anxious and worried. It was sad and frustrating, but also good to see people and share experiences. 2025-03-22T02:55:03Z https://yabu.me/nevent1qqsg2xwurv63fux0yskc6nnk372ecnlttkns3h9g7nw8vw285ct2eqgzyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08c7zaqa8 In reply to <a href='/nevent1qqst9c9n29m2sz5k5mln9sskavmajm5tcevzzl3aqc5ghydff02w4pq2h3cy0'>nevent1q…3cy0</a><br/>_________________________<br/><br/>I get the feeling there’s a magic trick to be made from those properties 2025-03-18T02:43:50Z https://yabu.me/nevent1qqsgpuzjmje6f8r6qqr8rwm94cw079n5c8rjamfuy8jguue2hydcxjszyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08ch42fyy In reply to <a href='/nevent1qqsys9r2amn2we494p89a2zgjjgpwu7tw99g6jtnr0wueg6lfjzphyg4wqxte'>nevent1q…qxte</a><br/>_________________________<br/><br/>The context is that Tressie said that the labor market for people with higher education has created a problem for higher educational institutions.

Tressie was not having it, so she clarified that (a) many people with those “studies” degrees do quite well, thank you and (b) the more important part of that story were predatory low-quality institutions, such as Trump University.

I would emphasize that the key is to recognize that the most important distinction between these phases is that they are separated by a phase *transition*.<br/><br/>Then I would note that the liquid-gas transition can be avoided altogether in the P-T phase diagram, and point out that this is possible because liquid and gas have the same *symmetry*. I’d then explain that the modern classification of matter prioritizes symmetry, and we’re off to the races with popular introductions to Landau theory, the metal-insulator transition, and topology.<br/><br/>Another thing I would want to mention is that different ground-state symmetries imply different excited states, so crystalline solids have phonons, ferromagnets have magnons, etc. When you add topology, you can get even weirder excitations, with fractional charges such as e/3, or (in principle) quantum statistics that are intermediate between fermionic and bosonic.<br/><br/>I took a look at the Wikipedia entry for “state of matter” and it is a hot mess, suggesting that maybe we should accept that its meaning depends on the context. I don’t really object to the solid-liquid-gas-plasma+ framework, but I don’t see anything fundamental about it.<br/><br/>Lastly, I think a much more important critique of Nayak’s claim is that it remains inconclusive! 2025-03-09T05:05:25Z https://yabu.me/nevent1qqsvjgrv3swhj9sllft64mtewwnucq37vqt4nvnm427vhzvt4f6c9vszyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08ce8m0t7 In reply to <a href='/nevent1qqs2fcglwsf86luppjudenad3pqf9vtj8cg24dcz969way6dh93l05qpzvseh'>nevent1q…vseh</a><br/>_________________________<br/><br/>I can answer your question about long posts!

I started out asking what I thought was a straightforward question about your essay: why seven? And I still don’t know.<br/><br/>If you want to hear my thoughts on how I (or another condensed matter physicist) might communicate about states of matter, that’s a different issue. It’s an interesting question that I can try to answer, but I’d like to understand first why astrophysicists might use the term differently. 2025-03-08T16:06:47Z https://yabu.me/nevent1qqsxdg8w0uywgsjpnvxqq2hry7crn29ft9rjg9m0qzspwj7tm36xrkszyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08czgxcjx In reply to <a href='/nevent1qqsfn2weg4hwypx2au5cghr655ag3cf8frpsvdh6a79n4p9fs673mls7wpt56'>nevent1q…pt56</a><br/>_________________________<br/><br/>I recognize that you are speaking to a general audience and my question arose out of a mixture of curiosity of confusion. I can see why you might think that this usage of “state of matter” might confuse more than it clarifies in this context, but I still don’t understand your assertion that there are actually seven. Why seven, and what is the physical basis for this classification? It wasn’t clear to me from reading your piece.<br/><br/>FWIW, I’d also say it’s arguable whether liquid and gas are different states of matter. On one hand, they are separated by a line of first-order phase transitions, with water being the go-to example that makes the solid-liquid-gas classification seem natural. But on the other hand, you don’t need to pass through this line to change from one state to the other, and they have the same symmetry. Technically, my working definition of a “state of matter” is that it is separated from another state of matter by a phase transition. I can augment that by recognizing states with different topology. 2025-03-08T02:41:36Z https://yabu.me/nevent1qqsruzzef0n8je0gjn0x2gvte6qhwr8xh7ufgu4jjytq3wd4t46dw8gzyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08chjznel In reply to <a href='/nevent1qqsz0l62eze3wg89k50ghlhkfc4fs9gd36xmpw02skm3rmhvku3525gxg7amm'>nevent1q…7amm</a><br/>_________________________<br/><br/>This usage is common in condensed matter physics and I don’t see your objection to it.

But historically, there were definitely people who put down condensed matter physics because they viewed it as mere application of more fundamental knowledge. Anderson introduced his famous “More Is Different” paper with a quote from Weisskopf that clearly placed “fundamental physics” at the top of a scientific hierarchy that had a corresponding hierarchy for physicists. And after he arrived at Stanford, Felix Bloch was so hostile to condensed matter physics (he called it dreckphysik, or dirt physics) and laser physics that most of the people who worked in those areas formed the Applied Physics department, just at the time that both fields were taking off. This kind of attitude is less of a problem today, but it hasn’t gone away entirely.<br/><br/>Sociology aside, I do think the condensed matter community could do a better job articulating our own view of what we think is exciting and fundamental. 2025-01-06T03:24:22Z https://yabu.me/nevent1qqsrqnwwptckstt5q3n0lzd8j8jge84w7536j6fntqlu7k7ayerswmqzyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08cpfhze4 In reply to <a href='/nevent1qqsz729zwp9pqud2efyul804nq8r86ulcdaur9n3uzt4af8ntupyzmq0pfz38'>nevent1q…fz38</a><br/>_________________________<br/><br/>My condensed-matter sensibilities bristle at the association of “fundamental” with the Standard Model and GR here, but I appreciate that you put it in scare-quotes and acknowledge the limitations of this definition.

Not sure if this was inspired by Feynman or just behavior that they had in common. 2024-12-04T02:31:58Z https://yabu.me/nevent1qqst2yn48esmcyurmhaf8u59zfz6crgm95273vyx04qlumwgwxyed0gzyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08cw9etsw In reply to <a href='/nevent1qqs9mqeau0t0d6s585x0u9qfv583cky56y6r003hprcx94fxnmlj6ksz8sane'>nevent1q…sane</a><br/>_________________________<br/><br/>Cory Doctorow has written about Bluesky and enshittification<br/><br/><a href="https://pluralistic.net/2024/11/02/ulysses-pact/#tie-yourself-to-a-federated-mast">https://pluralistic.net/2024/11/02/ulysses-pact/#tie-yourself-to-a-federated-mast</a> 2024-11-14T07:05:16Z https://yabu.me/nevent1qqsg5clacjkg5dq5q0tknm0knfvpp82pms2q9adncu65t59h5sngm5szyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08c6w6mxg In reply to <a href='/nevent1qqsdp2vpf3r2hw26aauvyn5rqfavep585e5695m9g5e7uexu3unvtrstw723h'>nevent1q…723h</a><br/>_________________________<br/><br/>Just today someone posted a nice photo that shows bright supernumerary bands<br/><br/><a href="https://socel.net/@robotwig/113141494674319261">https://socel.net/@robotwig/113141494674319261</a> 2024-09-15T21:45:26Z https://yabu.me/nevent1qqsdp2vpf3r2hw26aauvyn5rqfavep585e5695m9g5e7uexu3unvtrszyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08cke0ves In reply to <a href='/nevent1qqsx6clj5n2ygnfyyc0sjsgrg38hsmyr3lpjq62clnz8frlku9dnhngu32unu'>nevent1q…2unu</a><br/>_________________________<br/><br/>Diffraction does play a role when the droplet size is small enough, resulting in “supernumerary” bands below the main ones.<br/><br/><a href="https://archive.org/details/minnaert-light-and-color-in-nature">https://archive.org/details/minnaert-light-and-color-in-nature</a> 2024-09-15T21:41:52Z https://yabu.me/nevent1qqst375tyufeulwwmym5j765837z59s752ztcwflv2vxyvq6y3dexygzyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08c6gvs33 In reply to <a href='/nevent1qqsdex86hp8jhww6hgz8va7znsd9v96lsuvvfdpjf7yxakk2dqftppsl239t7'>nevent1q…39t7</a><br/>_________________________<br/><br/>Nice article! I look forward to the sequel(s). I’m perennially irritated that the typical “modern physics” course completely ignores statistical physics, and would like to find a way to introduce it earlier. Thinking in terms of frameworks might be a useful framework for that. ;)<br/><br/>It occurred to me as I read your piece that the joint limit k-&gt;0, h-&gt;0 could be tricky, in light of the Gibbs Paradox. I hope you’ll discuss it! 2024-09-08T19:32:26Z https://yabu.me/nevent1qqs8pd500h3zcugfvpp7hydgeapg83seyeam76mkr5jml5sxqtlsq8qzyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08c6avw3s In reply to <a href='/nevent1qqsgv8kfp6gg4h628sw5qf64hsmr60z34zxkh2jw86hm9y9lua6lz6qy9dm2v'>nevent1q…dm2v</a><br/>_________________________<br/><br/>That’s interesting and encouraging! I just looked up British Columbia and saw that our net intensity has routinely been below 100 tCO2-e/GWh because of our heavy reliance on hydro power (which is basically the same as 100 gCO2/kWh, unless I’m missing something). And recently we’re below 10! 💪🏼<br/><br/><a href="https://www2.gov.bc.ca/gov/content/environment/climate-change/industry/reporting/quantify/electricity">https://www2.gov.bc.ca/gov/content/environment/climate-change/industry/reporting/quantify/electricity</a> 2024-08-30T21:16:10Z https://yabu.me/nevent1qqspnmlyy6mpc22umxhvmfyqwws42lkpwyf88vuayswvwmu33d3rcrszyqzuqvyw0aaxx4n8a6wxuj77zz78e5sc40waasqxq8xknv490r08c0ca23p An #introduction: I am an experimental physicist at #SFU.
