  1. ..it was funny for mortal beings.. for gods it was absolute serious..
  2. Some said, if we would have condoms, we would not have Hitler, some said, if we would have condoms, we would not have Stalin, some said, if we would have condoms, we would not have Putin..
  3. ..with the exception of billions of flying objects (aka "birds") that are not/are hardly detectable by radar.. https://en.wikipedia.org/wiki/Bird_strike "A significant threat to flight safety, bird strikes have caused a number of accidents with human casualties.[3] There are over 13,000 bird strikes annually in the US alone." "Most accidents occur when a bird (or birds) collides with the windscreen or is sucked into the engine of jet aircraft. These cause annual damages that have been estimated at $400 million[3] within the United States alone and up to $1.2 billion to commercial aircraft worldwide." With the most famous case: https://en.wikipedia.org/wiki/US_Airways_Flight_1549
  4. "For instance, there is no way to definitively confirm if the self-driving feature was in use at the time of a collision, nor does the data consider if the other vehicle was the cause of the crash." People with electric cars, such as Tesla, drive mostly in cities. Meanwhile, statistics on miles traveled by non-electric cars include highways and interstate travels..
  5. How many of these were caused by autonomous vehicles? How many of them were deaths of the owner of the autonomous vehicle? If a motorcycle is traveling at 120 km/h on the road while an autonomous car is moving at 120 km/h in the opposite direction, and the motorcycle is heading straight for your (i.e., wrong) path (because it is overtaking another vehicle), a collision is unavoidable.. Radars, lidars, cameras, have limited (as everything) capabilities (resolution, refresh frequency, range).. To avoid collisions with other vehicles, ALL vehicles must be equipped with automatic assistance. They will exchange data with sufficient frequency and delay to tell everyone else where they are, so they will e.g. negotiate whether it is safe to overtake at a given place at a given time. You should not compare absolute numbers, but the percentage of deaths per number of autonomous cars (and it was turned on during the crash) with the percentage of deaths per number of non-autonomous cars. Without a investigation, it is not possible to distinguish between autonomous cars with autonomous driving systems enabled and autonomous cars with autonomous driving systems disabled. They could have simply collected them for statistics by looking at the car model.
  6. @StringJunky ...they rebranded McDonald's in Russia in 2022, to "Tasty, period".. https://en.wikipedia.org/wiki/Vkusno_i_tochka
  7. Things that are not directly edible by humans can be edible by animals, insects, bacteria or fungi, which will transform them into something edible for humans. Or converted into fuel, such as bioethanol.
  8. ..should I care about quotes from slave owners.. ? misogynists.. ? racists.. ? They treated people of other races, women, children as slaves.. "Passed by Congress February 26, 1869, and ratified February 3, 1870, the 15th Amendment granted African American men the right to vote." https://www.archives.gov/milestone-documents/15th-amendment Meanwhile, white (and all other) women.. "Passed by Congress June 4, 1919, and ratified on August 18, 1920, the 19th amendment granted women the right to vote." https://www.archives.gov/milestone-documents/19th-amendment (50 years later, after black men gained the right to vote, white/black/whatever women gained the right to vote)
  9. From what I see, none your post was put to the Trash Can, so what kind of censorship are you talking about.. ? What does spreading senseless hatred of people of another race have to do with science.. ?
  10. You are mixing "freedom of speech" with "freedom to spread hatred".. BTW, it is "funny" that you showed some politicians. Isn't it the job of the speaker of parliament to silence parliamentarians?
  11. ..you can buy a server, install forum software on it, and allow subscribers to say anything, including offensive things towards you.. I'm skeptical that you would let them do that. When criminals start using your forum and server to share child pornography, zoophilia, extremism of all kinds, you'll learn why forums have moderators who ban people for sharing such content..
  12. Are you thinking of placing an atomic clock on the Moon instead of satellites? This would require specialized devices that people would have to have on Earth to read them, such as GPS. Which is already built into most smartphones.. The distance between the Earth and the Moon is not constant, but variable. And like pointed already, not always visible. The Moon is currently at almost the point of perigee. The max distance between perigee and apogee (center-to-center) is ~ 51000km. 51000km/300000km=170ms error. The distance between the site on Earth and the device on the Moon will also vary due to the Earth's rotation. 6370km/300000 km=21 ms error. The currently existing GPS system has much smaller error..
  13. If you are not completely dumb, it is easy enough to figure out why racism is wrong.. Why should they let you to do so.. ? Forums, like any website, have owners. These owners set the rules for joining subscriptions. Do you let people who offend you, your family, or your friends, to enter your house (aka "website"/"forum").. ? I don't think so.. Thus, if someone misbehaves, they are asked to leave your property.. Site owners make money from ads. If a company that advertises on a site sees that their ads are linked to complete crap, they give up that opportunity.. To not being linked with it.. Completely understandable and natural. Major companies which paid for ads, quit Twitter when the dumbest billionaire on the world, let extremist make from it a swamp of hatred..
  14. Isn't this a rejection of dialogue?
  15. ..when i read people on science forums i want to rerun the simulation again.. (and even more if I read people on other social forums!)
  16. ..I have known many people who claimed to be scientists, but never bothered to do any experiment that could find something useful for humanity.. This forum is full of them, especially in the speculation section.. Being a "scientist" is not just about graduating from the right school or not.. it's about a general approach to the subject.. Priorities etc.
  17. You are an exception ps. People would be more interested in what scientific discoveries you made during your life. No one would care how much money you made (or Einstein, or Newton, or some pathetic politician).
  18. Of course it is feasible, but not in a capitalist world where everything revolves around money.. In a capitalist country, only what will bring a return on investment is done. A significant number of people waste their lives doing a job they hate, just to make money. A significant number of people waste their lives not being able to graduate from a good school because they and their family are not rich enough to send their children to places like Harvard, Oxford, MIT, etc. Teachers, scientists, engineers plan their careers based on how much they will earn. And they are even forced to do so because they have taken out student loans. Instead of working on their projects, scientists and engineers waste time begging management and investors for money for their projects. The amount of return on a project is the key to its acceptance or rejection. How much can you earn from a flight to the Moon? How much can you earn from a flight to the Mars? I would say nothing that can be earned in the current human lifetime. Billionaires will be even more reluctant to fly into orbit and similar risky tourism activities, after the Titan disaster. The first dead billionaire in a space accident is yet to come. It's not a question of "if", but "when".. There are places that will never be self-sufficient. The Arctic and Antarctic are not self-sufficient for the people who live there. UK and Japan are examples too. They have to import 50%-60% of the food people consume. "Japan imports about 60% of its food. Though the country usually is self-sufficient in rice, eggs, mandarin oranges and whale meat, it imports many basic goods, such as soybeans and cooking oil. Among developed nations, Japan is one of the countries with the lowest rate of food self-sufficiency. " https://www.culturalworld.org/how-much-food-does-japan-import.htm https://en.wikipedia.org/wiki/List_of_countries_by_food_self-sufficiency_rate
  19. This reminded me that there is such a proprietary Samsung app, Kies: https://www.samsung.com/levant/support/kies/ "How To Transfer Text Messages From Samsung to PC" "Step 1: Download and install Samsung Kies on your computer. Step 2: Connect your Samsung mobile device to your computer using a USB cable. Step 3: Open Samsung Kies and wait for it to recognize your device. Step 4: Click on the "Backup/Restore" tab, then select "Messages" and click on "Backup"." Google drive transfer text messages: https://www.google.com/search?q=Google+drive+transfer+text+messages To me it looks like a simple screenshot.. Then you paste the image into an email and send it to yourself, then open the image on your computer.. No 3rd party app is needed on any machine.
  20. Beer contains ethanol. In most countries, producers of alcoholic beverages must pay excise taxes on alcohol. The amount to be paid depends on the type of beverage, i.e. beer, wine, whiskey, vodka (basically, if it is distilled (high concentration) or not distilled (low concentration)). You should not compare the price of cola or sweetened beverages with beer, but compare the price of beer with wine and vodka, taking into account the percentage of alcohol they contain. For instance, beer has 6% of alcohol and is in 500 mL bottle. 0.5L * 0.06 = 0.03 L = 30 mL vodka has 40% and is in 500 mL bottle. 0.5 L * 0.4 = 0.2 L = 200 mL 200 mL / 30 mL = 6.67 x So, if one beer costs $0.75 (my price for beer), one vodka should cost $5 (but costs $6.75-7). i.e. it is more economical to buy 7 beers with the same amount of ethanol than single vodka.
  21. Russia's economy is a joke. It's just one big gas and oil station. It relies heavily on oil and gas equipment shipped from Western countries. "A proportional representation of Russia exports, 2019": https://en.wikipedia.org/wiki/Economy_of_Russia#Energy A country can have a huge GDP and a huge number of people, like China and India, i.e. a single person has very little of it.. https://en.wikipedia.org/wiki/Gross_domestic_product
  22. Meanwhile, the losses of the USSR (it's not Russia! Russia was only part of the USSR) https://en.wikipedia.org/wiki/World_War_II_casualties_of_the_Soviet_Union
  23. Why are you lying? https://en.wikipedia.org/wiki/German_casualties_in_World_War_II
  24. "The dose makes the poison" https://en.wikipedia.org/wiki/The_dose_makes_the_poison Everything is poison and nothing is poison, depending on the amount of..
  25. This is experimental physics - you take a tire, perform an experiment and get results that are put on a graph. And a few such repetitions and averaging them produces a graph that extrapolates to the rest. BTW, Formula One drivers like warm tires: https://www.google.com/search?q=formula+one+driver+like+warm+tires "warmer tyres are grippier on the tarmac and that is essential when driving a car which can be chucked around corners at 190mph. When lining up on the grid before the start of a race, the tyres are wrapped up in covers – acting almost like a blanket – in order to preserve as much heat in them as possible." A typical F1 driver uses 3 sets of tires for the main race. "On a standard weekend, drivers are given 13 sets of dry weather tyres, four sets of intermediates and three sets of full wets. An extra set of softs is reserved for those who reach Q3, while all drivers must use at least two different slick compounds in the race, providing the track is dry." "Street car tyres will last about 15,000 Km, but the life of an F1 tyre is between 60 and 120 Km. Since they are built for extreme performance at high speeds, the rubber wears off in no time. This is why team personnel rack their brains to change the tyres at the appropriate moment of the race and in minimum time."
