Ask Lemmy@lemmy.world•What do you think is a realistic peaceful solution to the China-Taiwan issue?English
13·22 days agoNot too serious a suggestion, but if migration worked once to escape the PRC why not do it again. Move all your industries offshore to an enclave or possibly several in friendly neighboring countries and then your population. I mean the population isnt so large that it’s not technically impossible to relocate. it’s not much more than some of the largest world cities. Then when invaded withdraw entirely. Anyone happy to live under Chinese rule can stay. Given climate change humanity is probably going to have to get used to massive migrations anyway. Horrible as that could be culturally being a semi independent part of another democracy would fix their declining population, plus being a massive economic stimulus all round. I suspect something like this may be happening informally anyway. Their main strength is economic and organizational so why not build on that.

Ask Lemmy@lemmy.world•What diseases do we never think of but should really know how to spot the signs of?English
5·2 months agoNot a disease as such but a condition. Sepsis aka blood poisoning, is a significant one for older folk. A fast heartbeat with low blood pressure, rash etc. It can be rapidly deadly but is not so easy to identify. About Sepsis warning signs
Treatment early enough definitely saves lives so it’s worth knowing about

Science@mander.xyz•'Drop Crocs' hunted prehistoric AustraliaEnglish
1·4 months agoI’ve updated the Illustration.
Seems like they got it straight from the university press release here. I guess we can cut them some slack for using a bit of AI given the recent job losses at that university. They are reported to have lost around 4000 full time staff places in the last year, part of Australia’s recent cut backs to universities that don’t get much international reporting. That’s may hurt their ability to do quality research. Professor Archer noted that "quite clearly, from the many fascinating animals that we’ve already found in this deposit since 1983, we know that with more digging there will be a lot more surprises to come,”. So lets hope they continue to get support.

Yep that’s not how science is done, but the real story is more interesting I think. It wasn’t Einstein so much as Hubble and Lemaître, but he did acknowledge the error that caused him to miss the expanding universe in his equations.
"This circumstance of an expanding universe is irritating " – Albert Einstein, 1929.
In every direction in the sky, there is a background fizz of light. It is all that remains of the most intense flare of energy ever emitted. To explain it, we must look back to 1929. At that time Edwin Hubble, an astronomer at Caltech, proved that the universe was much larger than anyone had expected and expanding in all directions. From this discovery, two competing explanations developed. The Steady State Theory and the Big Bang. The first allows the universe to create new matter as it expands. Matter just appears from some hidden and rather ghostly source. That permits the universe to look more or less the same as it does today, at least as far as galaxies go. The second treats the universe as a closed system. One that begins with a vast and concentrated supply of energy, which decays into lesser forms. Spreading out as it does. The Big Bang universe is an expanding bubble of space-time, with a few wisps of hydrogen and helium that form the stars. The origins of the Big Bang theory began before Hubble’s discovery. A Russian physicist, A. A. Friedmann had used Einstein’s general relativity to model an expanding universe. At this time, it was a purely theoretical exercise. No one realized then that our universe was expanding.
The rate at which the universe expands is known as the Hubble-Lemaître constant. That naming honours Georges Lemaître. In some ways he was the co-discoverer of the Big Bang. He was among the first to model Einstein’s theories of space and time across an entire universe. As a physicist, Catholic priest and astronomer, he had a clear perspective on this question. He had no problem with the idea of the universe having a unique origin for example. Both Einstein and others had learned that Relativity predicted an expanding universe. But at the time, there was no physical evidence of that. Einstein’s solution was to introduce an extra value to the equations. That balanced the universe’s expansion with an opposing force. For the moment, a stable universe seemed possible.
In the 1920s, astronomers were unsure whether our galaxy was the only structure in the universe. There was no astronomical distance scale. That might explain why most astronomers assumed a static universe. Lemaître was willing to explore a different option. He had seen the evidence from Erwin Hubble’s early observations at Mount Wilson Observatory in California. He published his theory in 1927. He estimated the speed of the expansion using those measurements. They proved that Spacetime was rapidly expanding, carrying along the rest of the physical universe.
Wherever astronomers pointed their telescopes every distant object was part of this rapid expansion. Lemaître understood that an expanding universe must have a tiny beginning. He called this origin point the cosmic atom, from which all matter emerged. Einstein rejected the significance of the new astronomical discoveries for some time. He maintained his belief in a static, unchanging cosmos until 1930, when he traveled halfway across the world from Berlin to Pasadena to see Hubble’s evidence in person. He examined Hubble’s photographs, looked through his telescopes, and declared himself fully persuaded.

He called the stabilizing term Lamda also known as the Cosmic Constant his “worst blunder” but actually it forms the foundation for our present understanding the effects of dark energy, the mysterious force driving the observed accelerated expansion of the universe.

Science@mander.xyz•Bird intelligence independently converged on similar skills to our ownEnglish
2·11 months agoFrom the interview: The main takeaway is that humans are special, but so are birds and reptiles. So our brains are amazing, but bird brains are even as amazing. We have neurons other species do not have. But the chicken, even the chicken, they do have neurons that we don’t have. So evolution has found so many different ways to generate complex brains, not just only one direct pathway from amphibians to humans. In this case, the tree of intelligence is a tree. It’s not just a single branch.
Ah that what happens when you Google an article which explanes some historical connection to Plato etc but it then uses that to make a completely unrelated point ie woke is bad. I should have read the whole thing before linking it. Looking at the other articles on the site it is indeed mostly right wing propaganda. A better point is Dawnkin’s post about Platonic forms here https://www.edge.org/response-detail/25366 in response to the question what scientific idea should be retired in 2014? He points out essentialism is a problem for accepting evolution, and for so many other things.
And Plato would have gotten away with it too, if not for those meddling kids and their cladistics. Essentialism has been hugely damaging and is the foundation of most types of Creationism. https://newdiscourses.com/2021/02/essentialism-logical-fallacy-plaguing-us-since-plato/



I’ve added the link, I agree I think they will have to relax the locality assumption of classical physics. The article does point out that it’s doesn’t really explain the reality underlying quantum effects. It’s at least some progress beyond many worlds or the Copenhagen interpretation which leaves it a black box.
