  1. How To Make Cassava Starch & Flour At Home: She received the starch around the 12th minute of the video, after it precipitated out of the liquid after several hours.
  2. The ultrasonic sound is used to measure distance by robots, such as the Arduino module. Its retail price is ~ 2 USD. It is used, for example, by automatic cleaning robots to detect obstacles in the way while cleaning dirt from the floor. https://www.arduino.cc/reference/en/libraries/ultrasonic/ ..so in the modern environment, in the city, things that emit ultrasound are literally all around you in toys that have some degree of autonomy, or in cars with automatic parking options, etc. etc.
  3. Does it need to be claimed? The problem is global warming, and the politicians (which you quoted, so I guess you support the idea) came up with the (yet another idiotic) idea of making even bigger problems i.e. taxes and tariffs. Why is Greta complaining? Her main objection is that politicians only talk about money.. I can't imagine who negated my answer, except the real Russian etc. agents and supporters of the gas and coal industry, because I am the biggest fan of the fight against global warming.. It's like the 2008-2009 crisis, they solved it in the worst possible way.. That's why people all over the world are against the "Green Deal", because it is simply a fraud.. CO2 certificate emissions? A fucking joke from the global warming..
  4. I assume that the words outside the quotation marks (i.e. what I quoted) are your own thoughts and are expressed freely, without a gun put to the back of your head? The idea that you can solve a problem with taxes or duties is quite naive.. Did not you (and friends) condemned ex-POTUS for his attempt to taxation/duties on Chinese stuff just a few years ago.. ?
  5. They (ab)used slaves from newly conquered territories.. "The conquerors/victors write the historical books".. "Countless" list of civil wars in the Roman Empire and Roman Republic: https://en.wikipedia.org/wiki/List_of_Roman_civil_wars_and_revolts ..almost every death of a Caesar triggered a civil war between pretenders to the throne..
  6. The fall of Constantinople took place in 1453. https://en.wikipedia.org/wiki/Fall_of_Constantinople
  7. The brain is a chemical factory. Feed it with crap (either literally and metaphorically) and it will malfunction. Healthy eating is fundamental. ps. I suggest hot spicy foods, such as Carolina Reaper sauce. Spicy foods causes release of endorphins. https://www.google.com/search?q=spicy+foods+causes+release+of+endorphins "Capsaicin tastes hot because it activates certain biological pathways in mammals – the same pathways activated by hot temperatures. The pain produced by spicy food can provoke the body to release endorphins and dopamine. This release can prompt a sense of relief or even a degree of euphoria."
  8. OpenOffice and LibreOffice are free, if cost is your biggest concern.. Alternatively there are online office/excel-like services. Even Microsoft gives one option for free, with limited functionality (not surprisingly). https://www.microsoft.com/en-us/microsoft-365/excel
  9. It is Adenine, not Amine. https://en.wikipedia.org/wiki/Adenine If you will start with making ball-n-sticks of chemical molecules of e.g. C5H5N5, C5H5N5O etc. you will see that they make hydrogen bonds with corresponding molecule in DNA chain. I 3D printed my own design of the ball-n-stick set. There are online ball-n-stick editors available: https://www.google.com/search?q=online+ball-n-stick+editors
  10. Before the invention of vaccines in the 18th century, mortality rates from some diseases (that practically no longer exist now) were very high.. "This differentiation was based on mortality during epidemics. Nowadays, virological methods can be used for this purpose. Worldwide, the mild form predominated (75% of cases of disease)[3]. The confluent variant of smallpox (Latin variola confluens) occurs in 2 to 5% of all cases; the mortality rate here is about 66% in vaccinated patients and 95% in unvaccinated patients; the hemorrhagic or black pox variant (Latin variola haemorrhagica s. nigra) occurs in approx. 3% of all cases, has an even more severe course than the confluent variety and usually ends in death, as does an even rarer variety called smallpox hemorrhagic purpura (Latin purpura haemorrhagica variolosa), in which death occurs extremely quickly, even before the rash appears[3]. " Air pollution indeed has influence on human health, but not on such diseases you mentioned.
  11. ..and I would say that your answer is primitive and childish.. ..only for the foolish who started everything from the Bible and took it literally.. Such an interpretation is too easy to mock, simply by saying that there was not enough time to create a stone from the bones of, for example, dinosaurs in the "calculated" time of life on Earth.. ..then who made up the Universe.. ?
  12. I don't anymore read books that don't have letters..
  13. That's pretty good advice for mortals like you, except for the Harry Potter series..
  14. I wonder, homework at your age and skills.. A new reincarnation has taken over your account..
  15. ..you seem smart, and yet you did not understood my reply.. Fairy teller/fortune teller tells the story ("the fairy tale"), and somebody reliant to it believes in it (the whole story does not really matter). Fairy tell differs, so do fairy tellers, but mechanisms is the same. People who believe that "5G is harmful" don't just take it from nowhere. Someone influenced them with this nonsense ("fairy teller"). They read it on social media, on forums specialize in it, and on custom websites which promote such things... ..this was just an example of a "fairy tale".. That's strange, because typically a computer, laptop, TV or smartphone are the largest (non-living) emitters of radiation source in a room, aside from heating...
  16. If someone was smart, he wouldn't want to be president.. (or king, emperor, or dictator etc.) The problem is those dumber presidents-to-be that we should avoid at any time..
  17. Your question is so childish that I don't know where to begin.. Every country has some leaders who are temporarily elected or have temporarily taken power over an area and have their own objectives, mainly to stay in power. They will support any side, as long as it allows them to rule a bit longer. Countries without natural resources (such as Japan) will naturally support anti-coal and anti-oil movements. Their goal is energy independence from other countries, which is difficult if coal, gas and oil must be imported. One country may agree with certain aspects of its enemy country, while disagreeing with other aspects that hit their economy (e.g., coal, gas, oil industries). The same can be said of a friendly country. There is no monolith in the West and there is no monolith outside the West. The world of politics is groups of common interests. They make temporary secret agreements among themselves. Sometimes it is obvious from other sources, such as economics, it is possible to deduce what they will support their partners in, without going into the details of their bilateral relations.
  18. ..I remember people claiming they would be rich because a fortune teller told them so in the cards..
  19. Have you heard that there are people who hold funerals for their sanitary napkins.. ? https://www.google.com/search?q=sanitary+napkins+funeral
  20. @Eise phileo + sophia = love of wisdom, in the distant past, with modern redefinition of this word, it is very hard to agree with it.. Many old, good-looking words have been redefined in such a way that they no longer have the same meaning as they did two or three thousands years ago.. ps. The marketing staff is even better at disgusting people for certain words..
  21. Michelson was biased and you are biased too. Other people responding here are also biased because they now take what they learned from books as dogma. Not many have equipment at home to perform experiments by themselves. It's hard to get past dogma, or even imagine that you can get past dogma. That's why the best results (discoveries) come from young students who have nothing to lose in the scientific world. Once someone gets a reputable name, it is very difficult to enter a controversial topic and potentially lose all respect. If you bought the required equipment and started doing physical experiments, the conversation with you would be much more fruitful. It is not very expensive. An investment of a few hundred to a few thousand dollars. Much less than the time spent on the discussion.
  22. No single particle has a shape.. The probability density function is not a shape.. We learn about particles (molecules, or macroscopic objects) from observations and the interactions they caused on other objects.. If/when photon is detected it disappears i.e. it is absorbed.. Beyond that? https://en.wikipedia.org/wiki/Lepton_number If you shoot at a flying birds with a shotgun, you will shoot several birds (I don't recommend this, it's just an analogy). If you shoot enough bullets, you should find out the size of the birds you tried to kill by simply looking at which bullets missed the target. The same is true for particles that can be placed at rest, in their rest frame, such as a proton or the nucleus of another element. The number of bullets is counted in the millions or billions. So you can get a pretty good image if you hit something and it is reflected or you miss.. We find out about the existence of one particle by hitting it with another particle, which we can control, e.g. a beam of photons, a beam of electrons, a beam of protons, etc. Unknown target hit by known source and observation what happens. e.g. a new beam of photons from that target (e.g. spectroscopy https://en.wikipedia.org/wiki/Spectroscopy ) If you have a better idea, you should start a new thread. But you'd better check it out for yourself. That's what scientists do, first they experiment, then they talk. You seem to be doing the opposite. ..one (you) can make experiment at ~ 0 K.. Did someone forbid you to do physical experiments? I said that neither the photon, electron, positron, neutrino, antineutrino, etc. have a shape... By saying "What is the unit of intensity?" I wanted to point out that intensity has already defined units that don't match your.. https://en.wikipedia.org/wiki/Intensity_(physics) "In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy." ..no one is forced to do so..
  23. The whole subject is so deep, I don't even know where to start.. How about pair production? https://en.wikipedia.org/wiki/Pair_production
