  1. "Even a Broken Clock Is Right Twice a Day".. If you will ask ~ 8 bln people to predict something in the future with an exact date, just because of the amount of people involved, some of them will give the exact date of some event, giving you illusion of prophecy and foresight. "predict a day of a week of your death". You have 1/7 = 14% chance of giving the correct answer. Nobody will say in media "that person incorrectly predicted day of week of his/her death". You will just see information about "lucky" one which gave the correct one. Someone is winning all these lotteries. The
  2. Properties in a big-city are expensive. Property tax, is an Ad valorem tax, that is paid annually on the current property value. https://en.wikipedia.org/wiki/Ad_valorem_tax https://en.wikipedia.org/wiki/Property_tax i.e. the owner of the property has to hand it over to the people who rent the property (otherwise he/she would have been losing money every year and eventually going bankrupt). Such tax is especially troublemaker for elder not wealthy people who own just one property and live in property (so can't rent it). They are eventually forced to sell property and movin
  3. One of the most bizarre topics.. US can't even solve much more basic things like: "Will America EVER ban guns?".. If people hadn't been shooting at each other for ridiculous things, we'd have had SOME PROGRESS... Police officers in a day, knowing they are being recorder are committing crimes.. WTF?! what do they do at night, when nobody is watching.. ?!
  4. No. That is an error. You want to know whether similar difference is between positron and muon+.. To have full set of information you need the all data from experiments performed on tau-/+, muon-/+ and e-/+. There is no single way muon can be created. e.g. it cound be result of decay of pion, but it can be also result of decay of tau. Scientists working on the OP experiment should verify whether muons created different paths have the same properites. If they vary, how much they vary.
  5. 30 kV is needed PER CM distance between electrodes.. so.. 1 meter distance requires 3 mln Volts. https://www.google.com/search?q=30+kv+per+cm
  6. Why are they keep saying "muons decay to electrons"? Only muon- decays to electron.. Muon+ decays to positron.. So actually they should make and compare the results from (at least) four versions of the experiment: muons- spinning in ring in one direction, muons- spinning in the opposite direction, muons+ spinning in one direction and muons+ spinning in the opposite direction. With particle spin polarized and without. Compare the results from muons- and + accelerated to different velocities until they decay.
  7. In static Universe, atoms could not form in the first place, stars could not form, planets could not form, galaxies would not exist etc. etc. It has nothing to do with strict biology.
  8. In static world there is no change. No progress. 1) decay of radioactive isotope of Carbon C-14. Carbon is part of DNA/RNA. Affected molecule is fatally damaged. Surrounding molecules can be damaged too by highly accelerated electron. https://en.m.wikipedia.org/wiki/Carbon-14 2) decay of radioactive isotope of Potassium K-40. Potassium is not part of DNA/RNA, but is present in blood and cells. It has a long half-life but has much larger abundance % than C-14 to C-12. https://en.m.wikipedia.org/wiki/Potassium-40 3) cosmic radiation from the Universe. 4) UV radia
  9. "Normal" procedure of repairing no-longer-produced electronics is to buy exactly the same electronics model from 3rd party user (can be damaged too), and replace part by part, until original one will start working.. From two-three-four damaged units, you can make single one working, if they have different kind of damage. Do you have enabled hardware disk-encryption? https://en.wikipedia.org/wiki/Hardware-based_full_disk_encryption Lost of encryption-key means inability to read data.. (Unless you're billionaire or government agency and have unlimited budget) Wh
  10. No. This is how economy works. In older times there was used previous metal instead of "worldwide accepted currency". Europeans wanted tea from China. But Chinese rulers demanded silver and didn't want anything instead. Europeans had to take gold on galleons, buy silver in Japan, and deliver to China. New cities-ports were created Macau and Hong Kong. https://en.m.wikipedia.org/wiki/Manila_galleon The all other ports were forbidden for foreign sailors from the West. It ended up with 1st and 2nd opium war. https://en.m.wikipedia.org/wiki/Opium_Wars Why Russia does
  11. Countries are importing goods from 3rd party countries and exporting their goods instead. To import stuff you need to have worldwide accepted currency. Nobody is paying any tribute other party. Without export China could not import what they want from world. Search net "what China imports from world". e. g. https://www.statista.com/topics/1471/imports-to-china/#dossierSummary They imported rice for 157 mln USD in February 2020. If they import such basic thing like rice, it means without it, somebody living in China, would be hungry..
  12. What is wrong with rice? I just ate it in my meal.. So the same like half of human population on this planet..
  13. The "emptiness" in natural sciences is called vacuum. A vacuum is a state in which in some volume there is very small number of atoms. The perfect vacuum is only theoretical. Through cosmic space there are flying billions of particles e.g. photons and neutrinos per second. Without them, it would not possible to see distant stars. The inventor of the first vacuum pump, Otto von Guericke, disproved Aristotle hypothesis: https://en.m.wikipedia.org/wiki/Otto_von_Guericke "With his experiments Guericke disproved the hypothesis of "horror vacui", that nature abhors
