    Excuse me, but it is 1,1,1,2,3,5... https://en.wikipedia.org/wiki/Alkane#Isomerism
  2. You are making a mistake by lumping all conspiracy theories together, scientific and non-scientific, when your opening post was about breaking the laws of physics. It is impossible to e.g. verify whether the mafia killed Kennedy or not. And to verify your conspiracy theory about gravity, all you had to do was attend physics classes at school. If you didn't have physics lessons at school, you are at risk of drinking the Kool-Aid. I have to agree with that. That is why elementary education in every field is so important, so that you can distinguish stupidity and falsehood. Otherwise, you have to rely on others. The better that elementary education is, the harder it is for falsehood to break through.
  3. I didn't have music classes in high school. They are compulsory in elementary school. They last for 4 years, from ages 10 to 14 or so. 32 weeks x 1 lesson per week x 4 years = 128 lessons. Didn't they teach you how to read music from a staff? I imagine that nowadays it can be done much better and easier than several decades ago. As long as you want to make it easier. I would use a touchscreen that displays hints about which piano keys to press in a given song. When learning to draw, the touchscreen can show you what movements you can make to draw something a few seconds before the movement. After several dozen such drawings or songs with support, you would draw and play like a pro. You can buy electronic pianos that have built-in key backlighting.
  4. Leeches are all those doctors, nurses, and drug manufacturers who demand huge bonuses for their services.. We have a scandal here involving doctors who were receiving.. 45 x (4500%) the minimum national wage.. in a public hospital (which is on the verge of bankruptcy). "After years of mismanagement, the facility has accumulated USD 11 million in debt, yet several doctors continue to receive astronomical salaries there. Four specialists cost the hospital USD 2.8 million annually. One of them, as internet users have discovered, earns extra money privately by seeing patients in his office and online." (currency converted)
  5. And I don't understand how you don't understand that. To put it bluntly, no matter what biased statistics show (because they are based (biased ;) on, for example, the number of Nobel Prize winners, or the number of peer-reviewed documents produced yearly by universities, etc. nonsense), the average American education system is simply poor. How can it be good if you choose what you go to school for? What you choose is what you are interested in. So, from what you are not interested in, you start to deviate even more from the average. In our country, students don't choose which classes to attend or not to attend, which means that after graduating from high school, everyone is more or less at the same average level. Choosing your classes is something you do in university. Physics, chemistry, mathematics, world history, world geography—these are things that are universal to the whole world. Only the native language, the history of the homeland, and the specialized geography of the homeland are things that are specific to a given country. Imagine that the average citizen of my country who finished high school after 1990 knows the geography of the USA better than the average American. What does that say about Americans? If someone didn't attend physics classes in elementary and high school, how are they supposed to not be susceptible to such nonsense? ps. Yes, we have physics and chemistry in elementary school. In most cases, “boring theory”. 2 years. ps2. I never had, for example, cutting up dead frogs—something you see all the time in movies for teenagers in biology classes in the US. No wonder you have so many serial killers—maybe someone liked those exercises... ;) Here, people learn physics, starting with Hooke's law, Newtonian gravity, and the laws of motion at the age of 12-13, and study it for two years. Adding two or more vectors is our elementary level for children. "Physics in elementary school usually begins in grades 7-8, building on knowledge from natural science, focusing on motion (speed, distance, mass), forces, energy, heat, electricity, magnetism, and optics, with an emphasis on practical observations and simple experiments, introducing students to the basic laws of nature and scientific methods. Students learn physical concepts and quantities, solve simple problems, and make observations, preparing them for more formal learning. "
  6. I did it. Twice. And made screenshots.. Nobody saw what you saw, that was point of my previous post. So let's talk about it, so that we can have a fruitful discussion at least once. And fix it once and for all.
  7. So many years all these LLM are on the market, and you still don't know that every time you ask some question, you get different answer.. I will ask twice the same question, within 10 seconds, and will get two slightly different answers.. If you wanted to discuss what mistake some LLM made, you should make screenshot. Here is what I got: Which part of it is wrong? ..a few seconds later..
  8. Did you try Open Office and Libre Office? Maybe they will load your existing projects if they are not too demanding.
  9. Install VirtualBox from https://www.virtualbox.org/wiki/Downloads Download Kali Live 2025.3 (not 2025.4! Unless you have Torrent software) from http://old.kali.org/kali-images/kali-2025.3/kali-linux-2025.3-live-amd64.iso Create VM with Kali Live 2025.3 ISO. Don't install anything just run Live VM. Install package which will let you have shared folder etc. It is in the VM's menu somewhere. From Kali open web browser. Use Google and search for "Windows 10 ISO". Download it. It may be https://www.microsoft.com/en-us/software-download/windows10iso Transfer to your Windows machine. Create VM with Windows 10 ISO. Install it. Now you can install your older MS Office on VM. When Microsoft sees you are opening a website to download Windows from Windows, it will open special media creation tool. But if you will open that website from other OS, it will let you download ISO file instead. Such ISO can be used to create VM. ps. The same you can have with Ubuntu Live or Mint Live. ps2. The same procedure for older Windows XP, Vista, 7, 8 etc.
  10. I had to check on Google what the price of electricity is in the US. $0.18 per kWh. That's BARGAIN. We (privately) have 60–80% more here than there. If you have a company (i.e., you have registered it at your address), the cost is 350–400% higher (> $0.65 / kWh) Let's Google more. Is this some kind of (unfunny) joke? Have Americans gone crazy from all this prosperity? When I had a server room at home 24h/7, my monthly electricity consumption + 14 hours of watching monitors (three LCDs) was at its peak around 320 kWh / month. And IMHO it was damn high. I reduced it to 75 kWh without much trouble, all I had to do was connect a wattmeter to all electrical devices and get rid of server at home.. ;) ..Some people have lost their minds with all this prosperity.. No one can consume $1800 / $0.18 = 10,000 kWh per month. That's how much you consume in 31 months with 320 kWh/mo. Unless someone stole it or grew a marijuana plantation, etc. The whole article looks like a bunch of unreliable nonsense to me..
  11. From my POV, Grok (from https://grok.com ) is unusable. I went now, wrote a question. "No response". And no more ways to ask anything. Refresh website (which clears everything). Same question. Response. OK. I typed my answer to Grok's response. And it is blocked again.. Refresh. Repeat. Again. Refresh. Repeat. Again.. UI looks cool, a lot of features not present in other models, but overall user-experience is WTF?! Seriously?!
  12. Everything consumed in excess has undesirable side effects. Drinking more than 6 liters of water a day can lead to death (for people weighing less than 75 kg).
  13. What excellent, in-depth, customer service! So Donald is now the proud owner of the collection. Me thinks he could make a fortune on XYZ tube.
  14. ...colonoscopy? So we can officially say that you are no longer an anal virgin... ;)
  15. To make kefir, I buy kefir and milk. I drink 90-95% of the kefir, pour fresh milk over the rest, and after 24 hours+ we have a new batch of kefir.
  16. LOL. The British estimate the size of a city/town/village based on the number of pubs located there... ;) ps. That wouldn't work in the Middle East ;)
  17. You shouldn't have built the Tower of Babel... ;) There wouldn't be any problems... ;) Do you know how to read ‘through’ in my language? fru
  18. To paraphrase you, regular chocolate and American chocolate are not the same thing either.. ;)
  19. I love perpetual devices! They always appear on forums and/or on the Internet.. and only in this aspect they are perpetual..
  20. You can always make a maple leaf in the middle and stars around it. Edit: Internet was faster: https://www.google.com/search?q=canada+flag+with+stars+mix+with+usa Gosh, they even made my version, I don't have to start Photoshop:
  21. The problem with LLM is that there are many models, even under the same name, with different computing power and different capabilities. Let me give you an example from last week. I launched ChatGPT and asked it to convert a piece of C/C++ code (brute-force calculation) into a mathematical function. It was the following piece of code: #include <stdio.h> #include <stdlib.h> int calc_total( int digits ) { int result = 10; while( digits-- > 1 ) { result *= 10; } return( result ); } int extract_digit( int value, int digit ) { int result = value; //printf( "value %d digit %d ", value, digit ); while( digit-- > 0 ) { result /= 10; } //printf( "result %d\n", result % 10 ); return( result % 10 ); } int calc_checksum( int value, int digits ) { int result = 0; for( int i = 0; i < digits; i++ ) { int digit = extract_digit( value, i ); if( digit == 0 ) return( -1 ); result += digit; } return( result % 10 ); } int main( int argc, const char *argv[] ) { if( argc == 2 ) { int digits = atoi( argv[ 1 ] ); if( digits >= 2 ) { int total = calc_total( digits ); printf( "total possible: %d\n", total ); int count = 0; for( int i = 0; i < total; i++ ) { if( calc_checksum( i, digits ) == 0 ) { count++; } } printf( "checksum possible: %d\n", count ); } } return( 0 ); }If you (reader, whoever you are) are an expert in mathematics/physics, stop reading right away the text below and try to solve this problem yourself as a mathematical puzzle. If you find this difficult, imagine an LLM doing this. The first ChatGPT told me f(n)=10^n/10 I answered, NO! you did not take into account that zero is ignored! It told me: my mistake, first zero is ignored, and gave yet another function. With just first zero skipped (sigh!) I answered, NO! all zeroes are ignored, not just first one! It told me: my mistake, f(n)=9^n/10 is the right answer. I answered, NO! For n=2, 9^2/10 = 81/10 = 8.1 which is a fraction! How can a fraction be the answer?! For n=2 the correct answer should be 9. For n=3, 72. It agreed with me, and used... some rounding operator... I lost patience, I asked: what version are you? It answered: I am ChatGPT-2. What? WHAT?! I have never saw ChatGPT-2. How on earth it is here, when it normally runs ChatGPT v4, v4-mini, and v3.5 was the oldest one... This time it completely locked up, and the only answer it could get was f(n)=9^n/10 It was impossible to skip it. Deadlock. A day later, at night, when I was expecting ChatGPT servers will be less busy, I asked what version are you. It told me: ChatGPT v4 with v5.2 engine. Let's test it. And it gave the correct mathematical answer for my C/C++ algorithm. Which was: The correct answer f(n)=(9^n+9*(-1)^n)/10 Shock, it did it! ps. And did you manage to do it yourself? I doubt it. The moral of this story is that you have to be an expert in a given field to detect LLM's mistakes, because its answers are very credible, yet often wrong, and it cannot admit its mistakes unless they are pointed out to it directly and it cannot digest them itself. It is impossible to use it to come up with something completely new, such as new theories of physics. Whether it answers will be highly prone to error depends on what you ask it, whether it's something trivial or something complicated. Asking it for help with the basics of computers carries a low risk of error (provided it's v4/v5). You have to be very careful which version is started. Different versions of LLM have different window sizes (ask it about its window size and it will tell you). v2-v3.x have 4k tokens, v4 has 16k, v5 has 16-32k tokens. Once the window size is exceeded, it does not remember what was previously written to it during the same session. The more you talk, e.g., for hours, the less it knows what you wrote at the beginning and loses context. And the chance of making critical mistakes increases significantly. Receiving code and writing code consumes tokens very quickly, so it will soon start writing nonsense. A few hundred lines and you're already outside the window size.

    Quantization exists in physics. Just like in computers. You have a floating point number: float x = 0; and float x = 1; What is between them? Many intermediates. But you don't know how many there are unless you've read the IEEE 754 specification (and most people haven't). https://en.wikipedia.org/wiki/IEEE_754 When you dig long enough, you achieve granularity, quantization, experimentally. In physics, as you mentioned in relation to a piece of wood, it is made up of atoms, and by dividing it long enough, you achieve the graininess created by atoms. The length of a piece of wood can be given in the number of atoms in a straight line. Your problem can be rephrased in simple terms: does the quantization of space and time exist?
  23. Seriously? https://edition.cnn.com/2019/08/19/tech/siri-alexa-people-listening If you're walking down the street and suddenly an advertisement for a store you're passing pops up, it's no coincidence—your phone sends its location (not via GPS, but GSM), and advertisements are selected based on that. When you log into your Google account, you will find a timeline of places you have visited in recent days and months. https://support.google.com/accounts/answer/14200149?hl=en Knowing where you are (where you live), getting information about the layout of the rooms in your apartment is a piece of cake. BTW, several hundred readings from GPS/GSM and the size and layout of the rooms are known. This is not private data, just diagnostic data. If you had read the terms of service, it would have mentioned this and you would have agreed to it yourself. If you bought your laptop in a store, did it have Windows pre-installed? Did you reinstall it right after purchase? During installation, Windows asks if you want to send diagnostic data (which could mean anything). I bet you didn't reinstall it five seconds after getting home.. i.e., the person who installed this pre-installed Windows or macOS, Android or iOS agreed to the terms of service on your behalf. ;) Last month, I saw something strange (at least to me): a guy (who knows a lot about cybersecurity—he even has a special card without which his laptop cannot be started) received a package from China with the best cell phone in the world in terms of specifications (not an iPhone), and he opens it, and the whole system is ready to go... I tell him, “Format the data! Reinstall!”... but he says no, no... What a complete idiot... even a regular DHL courier could have uploaded malicious software to it on the way to us...
  24. Easy. Change your citizenship. In our country, the tax on winnings over approximately $700 is 10% of the amount paid by the lottery organizer. ps. I think you would be happy with every win. The people who introduced these regulations did not elect them selves. It was necessary to vote for those who planned to abolish these taxes on winnings. If this had become a nationwide meme, politicians would have competed with each other in promising this or that, and if they had not kept their word, you would have held them accountable in the next election. ps2. Euromillions are tax-free in majority of European countries: https://www.euro-millions.com/tax When I went to the casino, I almost always left with a win. Why go to the casino to lose? That wouldn't make any sense... ;)
