  1. Are you able to explain your thought path that led you to such extraordinary conclusions.. ?
  2. ..or you were predestined to say such words.. Philosophical discussions can be shortened to the statement "I know that I know nothing".. If one needs brain exercises, one should start creating algorithms, i.e. solving solvable problems, rather than wasting (precious human life) time on unsolvable ones..
  3. Unwise. Used socks and shoes should not be given, exchanged, purchased or sold to other people - in this way it is very easy to get infected with onychomycosis and/or foot fungus. Onychomycosis ends with the old nail falling off and a new one growing in its place.. It takes many months..
  4. I used to get $2 socks for Christmas. They had to last for the next year..
  5. ..the founders of philosophy were slave owners.. they raped the women and men which they just bought in the slave market.. occasionally killing them for fun.. Did they have free will and use it to rape them, or were they determined to rape them? (in between of thinking about "philosophy")
  6. "philosophy can determine" something? Do you read what you write before you click the "Submit" button.. ? De-railed threads about nothing, just a thought.. Didn't I just say: ps. There are no participants in the discussion because people don't want to waste their time.. ..actually this sentence makes no logical sense....
  7. Whether an object is in the plasma, gaseous, liquid or solid state depends on temperature and pressure. The same thing can be in several states of matter depending on the pressure or temperature used. Check the diagrams of molecules or elements to find out at what pressure and temperature they are in which phase. Scientists began condensing gases long before you were born. One can measure mass of gas before liquefy and after and get the idea that they are the same with different volume (therefor different density), and the same number of atoms. As the liquid cools further, it transforms into a solid and reduces its density again (with a few exceptions, such as water). Every engineer who works with trains and railroad workers knows that metals expand when exposed to heat and contract when exposed to cold. Railroad tracks can bend when exposed to too low or too high a temperature if welded too tightly, which can lead to disaster. Look online for charts of elemental density versus temperature. An increase in temperature above a certain threshold, which varies for each element, causes electrons to be released from the atom. This may allow a further reduction of volume. The whole idea of a hollow atom came from the gold foil experiment, in which alpha particles passed through the metal almost transparently: https://en.wikipedia.org/wiki/Geiger–Marsden_experiments ..except for some that were deflected (when they hit the heavy gold nucleus).. The use of the cloud chamber also shows how highly accelerated alpha (and other) particles accelerate and eject electrons from other elements in their path. https://en.wikipedia.org/wiki/Cloud_chamber
  8. In the case of IPA, it evaporates: https://www.google.com/search?q=IPA+evaporation+time ..electronics engineers often use it to clean circuit boards, so it's pretty well measured.. there are YouTube videos that compare several different fluids.. This is not a single compound. Too ambiguous. Find the name of the compound, then review articles about it. ..I would use it without any serious doubts..
  9. People fly because of their brain size, capacity and power, not because of their muscles.. ps. Muscles bigger than the brain are only needed by MMA fighters, boxers, etc.
  10. The way you express your thoughts on the forum is cumbersome for people (too ambiguous), so don't have too high expectations for people to join and participate.. Any discussion with you is full of "what did you mean?" instead of a real discussion.. It is annoying and cumbersome.. Learn how to be non-ambiguous, and you will have more successful discussions.. ..what I see in this world is just: increase the time served in prison, increase the time served in prison.. I don't recall any politicians claiming that reducing prison time is desirable. Unless you meant "prisoners of free will" or "prisoners of determinism".. ? Of course, for society, the fewer people in prisons, the better, because these people simply waste everyone's time (except investors who bought shares in private prisons on the stock market, guards and prison management). Philosophical discussion belongs in the dustbin..
  11. C'mon. That's not the speed of light anyone here knows.. ..it is true.. measurements taken in space may differ slightly from those taken on Earth. that's why scientists fly into space and repeat measurements to see how they differ.. ..what if you own emitter and detector? Is the laser rangefinder not working? ..do you know the ,meaning of exponential function.. ? https://en.wikipedia.org/wiki/Exponential_function
  12. Depends on the people.. It doesn't work in the Middle East. If you think something "works", you are blatantly lying and/or you're an idiot. Generation after generation keeps the "secret" of who killed their father, mother, grandfather, grandmother, grandfather, grandmother, grandfather, grandmother, etc. etc. etc. Parents and grandparents share their hatred with younger generations.. Hatred is directed at people who have been dead for decades, centuries or thousands of years. Therefore, the hatred is directed at the living, who have no connection to the source of the hatred, and the cycle repeats itself. By killing them ("terrorists"), you create more of them ("terrorists")... You're terrorist, who created more terrorist.. I watched a documentary in Chinese. It was simple. A senior communist leader-teacher was training young workers how to deal with Western tourists on cruise ships, etc. They called tourists from Europe and the US "white devils".. This was not 50 years ago. Only 5.. Europeans or US citizens often think that "everything is fine".. because there is no war, etc. when hatred is growing all around them (directed against them) without their knowledge.. people are stupid.. Your grandfather murdered some grandfather/family member of theirs a few hundred years ago and they want/demand revenge and you are just a blatantly stupid tourist who just came to their country thinking only about your crap stuff and fun..
  13. LOL. Your sense of humor. The wave interference can be constructive or destructive.. We will be in a destructive interference phase when all the madness in Gaza will also disappear..
  14. https://www.google.com/search?q=the+victim+becomes+the+executioner "The victim becomes the executioner".. Mass murderers were often victims abused as children by family members, teachers, priests, acquaintances.. Whatever they do, they will create more "terrorists" and more people in the world who will want to kill him, his family, his nation and everyone else. "Terrorist-to-be" should be better informed so they know who to attack and who is responsible for their losses (i.e. who killed their family before they became "terrorist")..
  15. ..people have committed crimes.. not nations.. When you show their face, they are afraid of absolute justice.. .."the final judgement"..
  16. Massless means having no rest mass, i.e. being stationary, i.e. having no rest-frame of reference. https://en.wikipedia.org/wiki/Rest_frame It about detection rather than the rest - photon which is stationary could not be detected as photon.
  17. I share your point of view, but more chance of being hit by lightning.. (no more golf game? ) ps. If such a mortal is hit by lightning, some will say Zeus doesn't like him..
  18. ..which makes no sense, because there is no point in washin not dirty cloth.. ps. You should be an US politician.. ...brown prevents black? My cheap stuff does the same thing.
  19. Cheap things are intensely (artificially) dyed. What looks black in reality is not really black, but, for example, white with a black color that washes out after time. ps. Or dirty.. People rarely wash black cloth because there is no apparent reason to wash it..
  20. When programming, logging is an essential operation to find out what happened and why it happened. Especially in an application written on Linux and running on a server, without a GUI, whose output goes to a terminal / shell. I have created some basic C++ classes that can be useful in an application (C++, but they can be easily adapted to other OOP languages). Logs.Base is a virtual class without implemented methods. Logs.QuietLogs is implemented as a no-op. Simply put, nothing, quiet. Logs.Logs is implemented to write only about serious errors (Logs.Error() method implemented). Logs.VerboseLogs is implemented to write about errors and warnings (Logs.Warning() method implemented). Logs.VeryVerboseLogs is implemented to write about errors, warnings and notifications (Logs.Notice() method implemented). By passing a generic logging class object to functions, methods, classes, constructors, etc., they can write what they want to the logging object, but what appears to the user depends on user willingness to listen using -q (--quiet), -s (--silent), -v (--verbose), -vv (--very-verbose) etc. on the command line.. Writing to a separate log file can be as simple as creating another Logs.Base subclass with the appropriate methods overridden, or even over the network. // Logs v1.0 (c) 2023 Sensei (aka 'Q') (8.XI.2023) #include <iostream> namespace Logs { class Base { public: virtual void Notice( const std::string &message ) = 0; virtual void Warning( const std::string &message ) = 0; virtual void Error( const std::string &message ) = 0; }; class QuietLogs : public Base { public: virtual void Notice( const std::string &message ) {} virtual void Warning( const std::string &message ) {} virtual void Error( const std::string &message ) {} }; class Logs : public QuietLogs { public: virtual void Error( const std::string &message ) { std::cerr << message << std::endl; } }; class VerboseLogs : public Logs { public: virtual void Warning( const std::string &message ) { std::cerr << message << std::endl; } }; class VeryVerboseLogs : public VerboseLogs { public: virtual void Notice( const std::string &message ) { std::cout << message << std::endl; } }; }; class Program { public: Program( const std::string &title, Logs::Base &logs ) { std::cout << "Testing " << title << std::endl; logs.Error( "Error!" ); logs.Warning( "Warning!" ); logs.Notice( "Notice!" ); std::cout << std::endl; } }; int main( int argc, const char *argv[] ) { Logs::VeryVerboseLogs l3; Program p1( "Very Verbose Logs Test", l3 ); Logs::VerboseLogs l2; Program p2( "Verbose Logs Test", l2 ); Logs::Logs l1; Program p3( "Logs Test", l1 ); Logs::QuietLogs l0; Program p4( "Quiet Test", l0 ); return( 0 ); } Example output: ./logs Testing Very Verbose Logs Test Error! Warning! Notice! Testing Verbose Logs Test Error! Warning! Testing Logs Test Error! Testing Quiet Test I think passing arguments --verbose, --very-verbose, --quiet, --silent, etc. is quite sloppy in code.. better instead to create such a C++ class.. logs.cpp
  21. Of course, it is everywhere. It's like learning a language from the alphabet (characters). First the alphabet (characters), then words, then sentences. Your description (though it's accurate) is like starting from the opposite direction. Starting to read the book from the middle. That is, the person will have no idea where this Gibbs energy comes from and why all this happened (or not in the case of reaction which does not occur).. I was trying to say why the reaction occurs without bothering with what these A, B, C, D are. In my country, physics is/was taught from the same direction as discoveries and laws in historical order. Bizarre. Hook's law is/was taught first. I would say, it is stupefying people.. People learn about the energy released by a reaction and have no idea where that energy comes from.
  22. For all these wrongdoings, now even more people in the world hate Jews.. They are 1) idiots 2) love the fact that people hate them.. 3) they are idiots..
  23. It is very simple: from the state in which compounds have more energy (E=mc^2) it goes to the state in which they have less energy.. e.g. CO2 and H2O have less energy/mass per particle than sugar, fuel or so. The difference is extremely small, counted in eV/c^2 per molecule (and in chemistry expressed as J/mols or so), so by looking at g/mol is impossible to determine in advance, as the difference is billions times less visible. Such reactions are exothermic/exoenergetic i.e goes without any additional energy from external source. In the reverse direction, energy is needed from an external source. e.g. no energy source is needed to convert a metal to a metal oxide. But to convert a metal oxide into a metal, an external energy source is needed. This is why so few metals in nature occur in the metallic state (for example, gold, which does not readily form compounds with other elements). The energy is need to break bounds between elements, and the energy is released in breaking bounds between elements. It depends on the element and compound. Look at reactivity chart of elements: https://www.google.com/search?q=activity+chart+chemistry+wikipedia https://en.wikipedia.org/wiki/Reactivity_series Some (most?) elements/compounds need a certain "activation energy" to start the whole reaction: https://en.wikipedia.org/wiki/Activation_energy That's why fuels or explosives do not spontaneously combust or explode in most cases.
