  1. Hadn't heard of thulium before. There are just too many of those lanthanides to bother with
  2. ! Moderator Note If you want to talk nonsense about gods, then I suggest you find a more appropriate forum.
  3. ! Moderator Note This is a science forum. Please try to avoid posting nonsense like this. Thank you
  4. Such a process could probably have been done (with available materials) at almost any time after the stone age. The challenge would be the availability of those elements in their elemental form. Silver is easy: it is found as the elemental metal in nature. Silicon wasn't extracted from the oxide until the start of the 19th century. And, of course, there is no such thing as "tholium". Thorium, maybe? Also extracted early in the 19th century. So it could have been done in 1850. I am not going to watch because (1) it is a video and therefore the worst source of information known to man and (2) it appears to be about UFOs and therefore consists of lies and fairy tales. As evidenced by the bit you quote. Of course not. It is a video about UFOs.
  5. You shouldn't. It is pretty meaningless. You should ignore it. What you shouldn't ignore is all the people asking you questions and to clarify what you mean. Treating this forum as your blog is against the rules. You are failing dismally.
  6. How are you defining cooperate and compete with regard to atoms?
  7. ! Moderator Note A few blatantly off-topic posts (and, I'm afraid, some responses) have been hidden. The perpetrator has been given some time in quarantine to think about following the rules of the forum in future.
  8. 13mh13 has been suspended for a week for immature, offensive and generally trollish behaviour.
  9. I don't know, but it is possible that the person who wrote that is confusing "can contain" (is allowed to contain) and "can contain" (may actually contain). It seems odd that it would just happen to contain the maximum permissible amount. Anyway, the "safe limit" is determined as a level that is significantly below what can potentially cause harm. And then, as John says, it will be diluted and dispersed before it gets anywhere near the child.
  10. How about this, literally a jar: https://en.wikipedia.org/wiki/Leyden_jar
  11. You also believe you can ignore the syntax required by the forum.
  12. They would interact like anything else really. If they fell in they would add to the mass of the black hole. If they went past, they would be deflected (like gravitational lensing). They could orbit just outside the photon sphere because they have so little mass and typically travel at near the speed of light. (That is 1.5 times the event horizon radius.) But that would probably not be stable; the smallest fluctuation would send them towards or away from the black hole.
  13. Bit of data here: http://www.salute.gov.it/portale/nuovocoronavirus/dettaglioNotizieNuovoCoronavirus.jsp?lingua=italiano&menu=notizie&p=dalministero&id=4322 Follow the links to summary tables. And more here: https://www.worldometers.info/coronavirus/country/italy/ I can't immediately find anything on total death rates (all causes). But one thing worth noting is that well over half the deaths are in one region, Lombardia (and mainly in a small part of that). The top two regions account for 74% of all Covid-19 deaths. Whereas the normal (per capita) death rate is presumably fairly evenly distributed over the country. Also, it is thought that the death rate due to Covid-19 may be much higher in Lombardia because they are not able to test everyone who dies. And the overstretched health service may mean that more people are dying of other causes than they would do otherwise.
  14. The reason I immediately thought of the red blob being a data error was because there was a thread (somewhere) by someone who had based a whole conspiracy theory on a similar data problem.
  15. A law, in physics, is not a description of a principle; it is a mathematical summary of observed behaviour. That seems to apply perfectly well to Faraday's law. https://en.wikipedia.org/wiki/Scientific_law I doubt anyone cares.
  16. Is it on the equator? And vertically aligned with Greenwich in London? It might just be a default location for data that doesn't have a valid latitude and longitude (ie. 0,0). I don't know what the blob in is in the other pictures. Maybe an island (underwater mountain)? Or perhaps an artefact of zooming in to 0,0?
  17. Citation needed. The piano? Designed by a piano designer. Predicted by a computational chemist. First manufactured by a chemist. First theorised by a physicist. Further refined by other physicists and chemists. Manufactured by physicists and chemists. Invented by two German engineers. Started by software engineers and money men. All the advances you mention were made by experts in their field. (You might have been able to find a couple of examples from mathematics and astronomy; they are among the few areas where outsiders do occasionally make significant contributions.) Not a single one was the result of some random person with no expertise in the subject making uninformed suggestions. But this is just another off-topic hijack by the conspiracy minded. So we will leave it there.
  18. I'm quite sure that medical researchers with years of experience and expertise will be thrilled to see all these suggestions from random people on the internet. I bet they have been really struggling to come up with ideas.
  19. I would certainly ban the massive cruise ships; they bring no money to the local economy. (Dare I say it, just to the pockets of those who authorise them.) (But this is off topic, so enough said.)
  20. I think it was too polluted from all the boats (fish may have been there but not visible) and cruise liners. I must admit, I only read the headline not the article so it could be exaggerated!
  21. Fish and swans in the canals in Venice
  22. The FT has some very good graphs comparing progress of the disease in different countries an regions: https://www.ft.com/coronavirus-latest
  23. And, just to be clear, the "wow" is "wow, I will never cease to be amazed at the infinite variety of humanity; not intended as a disparaging comment (which, I guess the downvote suggests).
  24. Ah yes, the complete absence of evidence just proves how deep the conspiracy goes. (Blimey. I thought you were joking. You’re serious!? Wow)
