  1. Where did they get these values? The only way to learn about state of an atom is continuous beam of e.g. photons and electrons toward particle at examination (aka "observation", "measurement"). If you don't observe/measure ("send electrons/photons toward it"), it can get any undefined state (i.e. randomization routine could be called, the next time somebody tries to examine it). If you can randomize almost everything, you don't have to store almost anything.
  2. ..but he is talking about "matter wave" aka "de Broglie wavelength".. i.e. in diffraction or interference experiments with electrons you use de Broglie wavelength.
  3. Don't mix "matter wave" aka "Broglie wavelength" with wave-functions of probability of finding electron in atom and/or molecule..
  4. Simulations of particle collisions are done on daily basis at CERN. You can even download the software.
  5. Antivirus is as good as virus database it has access to. Newly found dangerous threats are found by team of antivirus programmers and added to database on daily basis (in the Windows OS world at least). Antivirus connects to central server and automatically updating local copy of database. If you will burn CD with antivirus app, you will have to download virus database manually.
  6. But "all swans are white" is false statement. Some swans are not white. The key word in this statement is "all". If statement would be "majority of swans are white", finding swan with different color would not contradict statement.
  7. The key word here is "every"... No, it would not. It would show that "In every room in every building on earth, there's a green unicorn!" is false statement.
  8. In the OP, you called scientists "cowards", when you could downgrade it to "scientists are afraid of losing respect of colleagues and end up as crackpot scientist".. Like everybody else, they want their career to grow up, and want to be famous in scientific community. Controversial hypothesis and theories could stop their career.
  9. Let me check the source code. Oh, it is because of these lines of code: if( person.think.equals( "world is simulation" ) && !person.isGodMode() ) { person.think.inject( "world is not simulation" ); person.think.inject( "reject" ); }
  10. It does not. Notice horizontal line where is 101 on the left vertical arrow. That's normal air pressure line (101 kPa) on the Earth (including your freezer). Sublimation triple point is at 0.6 kPa = ~600 Pa, and temperature 0.01 C. Big dot on the image above.
  11. No. float is 32 bit. double is 64 bit. They are fixed. You can read more in what range they operate on e.g. Wikipedia:
  12. I already explained my idea how to not have to use pesticides at all, in couple other threads. Basically there are needed hermetic farmer skyscrapers. If bugs, fungi, microbes get in some floor, just one floor must be decontaminated. They could also reduce needed water and power usage. Reduce to zero losses caused by flooding, hail or ground frost. Pesticides kill not just unwanted organisms but also kill bees and other insects required for reproduction of plants. This caused major issues in e.g. China.
  13. int PNP; double root, estimate = 7; float x, pnp_check; For a start change it to: long long PNP; double root, estimate = 7; double x, pnp_check; "long long" is 64 bit signed integer.
  14. It is to have work activity that you LOVE to do.. Why people are quitting job ASAP after winning the lottery? Because they HATE their daily job.. Recently there was thread about "purpose of life". If somebody would be immortal and having to do job he or she hates, for eternity, it would be like being in the hell for eternity.. People doing their hated jobs dream of retiring. That is really sad life.
  15. Finite real number can be infinitely divided . double value = 1.0; double divider = 2.0; for( ;; ) { value /= divider; printf( "%g\n", value ); } (forget that double or float in C/C++ is just 64/32 bits)
