For instance the viscosity of the magma and the would be lava tends to give a reasonable expectation of the explosive power of the volcanic eruption if it occurs. And this viscosity is determined by the composition of the minerals in the material like check this link out https://upload.wikimedia.org/wikipedia/commons/thumb/f/f4/Mineralogy_igneous_rocks_EN.svg/300px-Mineralogy_igneous_rocks_EN.svg.png basically the rhyoliticic end is where you get the high viscous stuff. But in saying this you'd never be able to pin point where an eruption is going to occur just based on knowing information about minerals, as that tends to be caused by much larger scale interactions such as hot spots and lava plumes. As such I think the area of Geoscience is incredibly interesting when it comes to emergence with how you can see the impact of things at atomic scales (such as the fact an area of rock, would be more resistant to weathering if it is made up of harder minerals such as quartz which is also determined by atomistic interactions to form strong crystal structures), but have incredibly emergent phenomena throughout.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-2344899366722989882024-03-08T17:37:42.964+10:002024-03-08T17:37:42.964+10:00It is a nice table.

I am thinking about it. There are many factors involved in any social change. It is a complex system! But I think contributing factors of the rise of neoliberalism and of BS in society at large, the rise of BS, and the availability of metrics. Hope I can write more later.Ross H.

One cannot understand when social sciences journals have double blind peer review , why it is not a practice in science journals. For example , Nature group has these intermediate editors ( new creation for this century) , They send it for peer review. As soon as they see the country and from where the paper is coming from (single blind) there will be a bias to dispatch the article for peer review. <br />The whole publishing regime is in a flux , with retractions and the rise of science integrity specialists. Science is evidence based and social sciences is opinion based ( unless a Pierre Bourdieu comes through with good social theories) . Social sciences journals seem to follow a better path for integrity . Evidence based science journals should have double blind peer reviewing.

As I am sure most people from the era would be able to feel there being a change as compared to now, but at which point in time do you think it can be argued science changed and what do you think are the causes. Personally I think the insecure contracts and the way funding is so competitive now with minimal any high risk science or science done for knowledge's sake being done anymore. Or I guess the fact if you do not publish so many papers in good journals each year there is a risk you will lose your job, so it seems we are all just stressed trying to keep our jobs.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-81249020116681501782024-01-19T18:39:15.545+10:002024-01-19T18:39:15.545+10:00I found your exploration of emergence in nuclear p...I found your exploration of emergence in nuclear physics fascinating. The way you break down complex concepts into understandable analogies makes the topic accessible. I think If you want to pursue higher education in the fields of Science, Engineering, Information Technology, etc. then you'll need to have a strong knowledge of physics. Physics is the one subject that connects many other subjects in one way or another. Self-study is not enough, you'll need the help of a physics tutor to understand the difficult concepts of physics.Rum Tanhttps://smiletutor.sg/physics-tuition/noreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-92073089657355495392024-01-19T09:36:32.493+10:002024-01-19T09:36:32.493+10:00Thanks for the comment.

If you just lower the temperature, you will get equal amounts of each rectangle domain that on average add up to a square. But if you strain the material along one axis, the system will prefer one rectangle over the other and switch to that orientation until the material elongates enough to relax the strain (without any plastic defects, just reversible domain wall motion). If you release the strain and raise the temperature again, the material returns to a single square domain with its original shape. <br /><br />One way to think about it is you are reversibly melting and refreezing a symmetry-breaking microscopic strain degree of freedom while the overall structure remains a solid. It is analogous to magnetic degrees of freedom in a ferromagnet, which can be reversibly poled by an external field and then returned to the paramagnetic state at high temperature.<br />KGhttps://www.blogger.com/profile/05079962901471180520noreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-37595917731406306362023-11-09T19:48:34.011+10:002023-11-09T19:48:34.011+10:00Dias in trouble again https://www.nature.com/artic...Dias in trouble again https://www.nature.com/articles/d41586-023-03398-4Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-3432117067682788112023-10-31T22:42:47.640+10:002023-10-31T22:42:47.640+10:00Great summary Ross!

Out of curiosity what is your interpretation at present of what the pseudogap's connection with the superconducting phase is if any?

Moreover, for the pseudogap, the phase boundary is not well defined, being different depending on what experimental probe one uses to define it. Hope that helps.Ross H.
