  1. Make a document, print it out, and place in toilet in visible place from WC..
  2. Google does the conversion, you don't have to visit any website.
  3. Google does the conversion, you don't have to visit any website.
  4. Google can do that. https://www.google.com/search?q=100+celsius+to+fahrenheit It works with other physical units or currencies, etc. ..this way you can learn something.... Make Excel/Open Office Spreadsheet once, and then you can use it forever.
  5. ...and these are who are not so easy target for propaganda and lies..
  6. At least 50,000 of them were IT software engineers. https://en.wikipedia.org/wiki/Russian_emigration_following_the_2022_invasion_of_Ukraine "Those who have fled tend to be young and well-educated professionals, leading some economists to suggest that the Russian brain drain is worsening.[24] More than 50,000 Russian information technology specialists have left Russia.[25]" "to the poor only the wind blows in their eyes"..
  7. Those who were wise fled the country on February 24..
  8. Russians' worst enemy is other Russian. They have adage: "у нас много людей" ("we have a lot of (dispensable) people")
  9. People searching for food in garbage bins do not have mental illnesses. They are homeless, hungry without cash or freegans.. If this is a problem, don't eat in restaurants.. When customers too often have diarrhea after dining at a restaurant, they remember it and stop going there, and such a place is on a straight line to bankruptcy. It is in the restaurateur's interest to ensure that the food is of the best possible quality, so that customers return and praise the stay, rather than discourage their friends and family.
  10. Photons are emitted by some material, for example, as a result of the temperature of an object (thermal emission). When they hit some material, they can be 1) absorbed 2) reflected 3) refracted. The chemical and physical properties determine at what frequency/wavelength/energy of the photon this will occur. Material may be transparent at one pressure and temperature and opaque at other conditions. We see things around us when photons are reflected by an object toward us and the eye absorbs the photons, causing an electrical impulse to be sent to the brain to decode what we see. The lack of photons in the visible range of the spectrum does not mean that we cannot "see"/detect objects, e.g. radar does this at different frequencies than our eyes.
  11. Perpetual motion on Earth will be slowed over time by 1) friction between an object in motion and air particles 2) gravity.
  12. Science is experimentally proven knowledge gathered over hundreds and thousands of years of human development. If the thread is closed, you are most likely making up things that are not mainstream science and/or even contradict common knowledge.
  13. You didn't mention what pressures and temperatures have to have these solids.. What at STP is gas, at low enough temperature and/or pressure can be solid i.e. one can have a piece of solid Chlorine (below −101.5 °C) or other stuff.. Alkali metals and ice? They release hydrogen, which, when in contact with Oxygen from the air, can ignite:
  14. Random mutation. First seen just because it has just appeared in your lifetime. e.g. resistance to drugs that have just been made by human.
  15. YouTube and other websites sort content by the number of likes. The most liked content is shown first, so youtubers ask their users to like the video and subscribe to the channel. There may be other rewards for the most liked content, such as higher ad rates.
  16. Without the influence/existence of the USSR, there would be no communist China, but a democratic/republican China. Without the influence/existence of the USSR, there would not be a communist Vietnam, but a democratic/republican Vietnam. Without the influence/existence of the USSR, there would not be a communist Korea, but a democratic/republican Korea. Without the influence/existence of the USSR, there would still be hundreds of millions of people still alive and their unborn child..
  17. Hydrogen-4 (H-4) decays to Tritium (H-3) and one free neutron. So, if you hit Tritium (H-3) by free neutron, it could be converted to Hydrogen-4 (H-4) and after a while (ultra short), it will decay back to Tritium and emit free neutron. Giving none or subtle traces of reaction like e.g. change of path of neutron and/or little delay. https://en.wikipedia.org/wiki/Isotopes_of_hydrogen But it is extremely fast decay (in yoctoseconds). "Another atom"? It must be the same type of atom as the one hit, otherwise the rules of conservation would be violated, no? or.. can it emit something else (e.g., positron, electron, proton, alpha or whatever), besides the free neutron? Free neutrons differ in their kinetic energy. That is why they are called cold/slow and hot/fast neutrons. https://en.wikipedia.org/wiki/Neutron_temperature#Slow https://en.wikipedia.org/wiki/Neutron_temperature#Fast https://en.wikipedia.org/wiki/Neutron_temperature#Ultrafast If you hit Deuterium with a free neutron with a kinetic energy greater than 2.22 MeV, it can yield a free proton and a free neutron, and your original free neutron. Other isotopes that decay by neutron emission are He-5, He-7, He-9: https://en.wikipedia.org/wiki/Isotopes_of_helium
  18. Why would any sane person want to repeat the nonsense that some random person from the Internet, who wants to be famous by writing nonsense, repeats on a scientific forum?
  19. A person may be allergic to contamination present in water rather than pure (distilled, desalinated) water. Drinking contaminated water, can give the mistaken impression that it is the water that causes eczema. The water present in beverages, plants, fruits, sold in stores comes from different places, different regions of the world, and has none, minor or different contaminants.
  20. Not big enough to accommodate all the egos of V.P. and Donald T. ....
  21. Wow. Facepalm. The thread is about how to lower already excessive energy prices, and you suggest how to make things even worse.. ? Do you have any idea that increased energy prices would be immediately passed on to customers, i.e. everyone? Baker needs energy to heat stove. The same with almost all businesses, farmers, transport.. Higher costs of food production, higher costs of delivery of food and other goods to shops, higher prices of rental housing (gas, electricity) and so on, so on.. Increased taxes are always passed on to the end customers, or business in capitalistic country must be shut down. The UK is a net importer of food ("In 2020, the UK imported 46% of the food it consumed"). Maybe Brits should eat less (some obese, for sure) and have one shower per week, or month, and have to go to sleep at 18 to not have to turn lights on when it is dark.. ..sounds like you're talking about domestic energy usage.. which is just a part of country energy usage.. Business and farmers are also energy consumers. Increased costs of fuel will have result in inflation of price of whatever they produce or transport. It is easy/easier to reduce energy usage by individual customers. For example, make free buses and free city public transport, and less people will use private cars, reducing air pollution and carbon based fuels use. Refrigerator is not an essential accessory (especially in winter, I keep meat on the balcony). There are refrigerator-free food preservation methods like pickling, which worked for thousands years. The city can reduce energy consumption by turning off streetlights late at night. During the first wave of COVID-19, local authorities turned off the streetlights completely, and for the first time ever we had the opportunity to see the stars without the light pollution of a big city. The city can reduce energy consumption by closing public offices and schools (the energy needed to heat them) and using online alternatives. UK residents are at least fortunate (so far) that they don't have many days of -20C or -30 C in a year like we do. The price goes up because demand is high and supply is low. If demand decreases, the price will naturally fall. There is space for many optimizations and improvements. For example, a baker could be informed before starting work how many buns and breads are needed for the next day. IT could make an app that connects end customers with producers of food that cannot be stored for long, as in the case of a bakery. Exact quantity = less waste = less energy demand.
  22. Sensei replied to kenny1999's topic in Chemistry
    Temperature is not the only factor to consider. There is also pressure. e.g. water boils below 100 C when the pressure is reduced.
  23. Why do you think quantum effects have no impact on neural processing? Everything in the macro is just a "quantum effect," only multiplied and repeated in billions of various interactions.
  24. ...there is needed imagination and the foresight to "click this in the right order to get the reward ("cookie")"....
