  1. Apology readily accepted. I found your post surprising, as it was quite out of character for you. Thanks.
  2. In the first example the author states "However there is too little information currently available to suggest that this site has any responsibility for the differential performance of skeletal muscles with age". I suggest that "differential performance" suggests a quantitative difference on some spectrum of performance. For example an aged muscle deliver 20% less power than a young muscle, or its twitch rate is reduced by 35%. A "different performance", in contrast, would suggest a qualitative difference. I know nothing about muscle physiology, so this example is by way of a guess - a qu
  3. OK. Thank you for the reply, though I could have done without the scathing sarcasm. I was interested in your comments and wanted to be sure I understood your thinking. Perhaps I'll take a remedial reading comprehension course.
  4. The article you have linked to is very poor quality. Why have you not at least gone to wikipedia, which is typically very reliable for basic facts like this? This would at least have answered half of your initial question. Since, I've now pointed you there I hope there is no harm in telling you what you will find. Proxima Centauri b and Proxima Centauri c are the names given to two planets that have been orbiting the star Proxima Centauri. @TheVathas not only given you hints to the second part of your question he has basically given you the answer - assuming you know basic trigonometry.
  5. My recollection is that research in the last decade has suggested the Earth may not be engulfed. This as a combination of two factors: the sun will not expand as much as earlier estimates suggested; Earth's orbit will increase slightly, as you noted for Mars, because of the reduced solar mass. I haven't located the relevant paper(s) yet, but will post if I can track it/them down.
  6. Would you restrict that to Piers? Or do you just see Jeremy as an outlier on a leftist spectrum? He was, after all generally consistent in his positions, which is not typically 'nuttish'.
  7. A small correction: I think you are recalling the Hungary vs. USSR match. The "blood in the water" being a reaction to the brutal suppression by the Soviets of the 1956 Hungarian uprising. On the main thrust of the topic, sport can definitly be a unifying force, but only amongst those inclinded to favour unification.
  8. Well, no. That is incorrect. I share @beecee 's hesitancy to say too much, since that would be providing an answer in the Homework section. beeceee gave a nice clue - that also references why your post is incorrect - when he noted the lower case 'b' and 'c'. They are used to indicate something rather specific and it isn't that Proxima Centauri is a double star.
  9. Excellent. May I count on your support for the small, oft excluded and, frankly, never even recognised group of Balding Britons with Bad Breath, Big Bellies and Boring Biographies?
  10. Keep in mind that lurkers read these threads also. They may well outnumber the participants, and even the non-participating members. The post was an opportunity to educate some of them.
  11. The search for evidence of life by Perseverance falls into two categories: From sedimentological studies identify environments that could have been habitable. For these instances: Use the onboard analytical equipment to search for biosignatures. Look for possible fossils - I have not yet tracked down the specs on the Perseverance camera system, but supecte detection would be imited to macrofossils. Cache promising samples for eventual return to Earth for comprehensive laboratory analysis Edit: Full camera specs in this paper. The re
  12. No problem at all. I'll transfer the blame to you. I wasn't aware I had called anyone out as a troll. Would you elaborate? Nor have I. I reached a provisional conclusion that the OP had a selfish attitude. I offered them two options, one hyperbole riddled instance where they proudly refused the vaccine and another where they did the socially responsible thing and took it. They (and you) appeared to miss that second option. I've reread my post several times and am comfortable that the option was clear unless one chose to be deflected by the hyperbole. Or, to put it
  13. How do you define evil? Without knowing that, disection of your thesis is difficult. As @Bufofrogpoints out, evil is a human construct. Are you exploring the role of evil in human evolution only, or in all evolution? If all evolution, are you imagining organisms other than humans can practice evil?
  14. M.I.T. say he's not a scientist. Sheldon Cooper says he's not a scientist. That's good enough for me. It ought to be good enough for you.
  15. That was my impression. And not as amusing as some of the time wasters.
  16. If I aim a reply at a silly post, does the reply share the inconsequence of the post?
  17. All of my money is tied up in loose change!
  18. While this is true I doubt that the natural processes of weathering will be significantly affected by the tensional forces discussed in the paper. I gave some though to mentioning metasomatic and metamorphic changes, but could based on the abstract the authors do not appear to directly suggest those. I should expect enhanced metasomatism via increased micropores in a tensional environment. Enhanced metamorphism seems unlikely - perhaps @beeceecould say if the paper offers examples of such in the Turkish locations referenced.
  19. Surely the key word in @MigL's post is "typically"? He suggests, and I agreee, that typically an engineer applies known science. Applies is a key word in my sentence. Engineers are (typically) engaged in the application of principles. Scientists are (typically)engaged in the derivation of principles.
  20. You are mistaken. Scientists seek to gather knowledge. Engineers seek "build" things. I have worked with scientists and with engineers. I have worked as a scientist and as an engineer. The two minds sets are different. The methodologies are different. The aims are different. I repeat, you are mistaken.
  21. A handful of disparate thoughts on the topic: I wonder @beecee if the words "tremendous damage occurs to areas of Earth's crust" are yours, or from the paper. I would not characterise deformation, whether folding, or faulting, as damage. Damage is something that happens to objects with a purpose that interferes with that purpose. Deformation is something that routinely happens to rock. In the context of this forum the casual "tremendous damage" is fine, but if those are the words of the authors I am rather surprised. I agree with @studiot that the slab pull- break off is not new. Wit
  22. What do you mean when you talk about "competing with China"? If I plan to run 2,000 miles this year and my neighbour is targetting selection for the GB athletics team over 800m, are we competing. We're both involved with running, but our goals are quite different. China has first and foremost political goals in space. Second they are targeting political goals. And, of course, political goals are also important to them. In contrast SpaceX's aim is to make humanity a multi-planet species. Where do you see the competition? Chinese plans to take over Mars? Could be, but what is your take?
  23. A very crude measure of the amount of research on a topic is how many hits are generated by a google scholar enquiry. That returns, for "neurobiology", about 1,070,00. How much larger do you think it should be?
  24. Happy to help. It's wrong. For example: An eastern gong is disc shaped, so saying that the disk is shaped like an estern gong, is not really telling us anything new. It's a disc. Slates vary considerably in mineral composition, micro and macro texture, and the properties such as density, compressive and tensile strengths, etc, that are dependent on them. You need something much more specific than just identifying it as a slate.
  25. Not really. There is overlap between the disciplines, but they are distinct in both their methods and their objectives. A scientist can adapt to engineering work given time and appropriate training, and vice versa, but that does not make an engineer a scientist.
