  1. (...) Strange is working the nutt cases in physics (...) Strange joined this forum in Feb 2013.. Zolar V couldn't know him.. Air forces don't offer Internet? Very nice, at least we will have somebody new, knowledgeable. Welcome back!
  2. "Chicken scratch" changes with time, and because of temporary or non-temporary influence of drugs or other mind-changing substances like alcohol.. Somebody with e.g. shaking hands because of e.g. illness, can have extremely hard to read text.. It does not tell anything about state of mind.. The more important is what somebody wrote, than how somebody wrote it..

    I see reason. To become smarter.. I am always entering my LaTeX by hand using codes. The more you're using it, the more comfortable you feel using it.
  4. Actually it's easy part. When application is connecting to the server, it negotiates encryption method. So if person is under "legal surveillance" (which the real judge approved! After seeing the real evidences which make crime plausible to happen, not "one big stamp" (quote from "Snowden" movie) ), server set up weak encryption, or none at all, and everything can be caught and decoded.. User is not even aware whether encryption is hard, weak or none.. I am against any type of electronic surveillance. There is no proof that somebody said or wrote words which were delivered through Internet. Anybody can pretend anybody. e.g. I could hack in Swansont, Phi for All, String Junky etc. etc. accounts on this forum, wrote anything on forum, and nobody would notice it's not message from the real member of forum. What is worth such "evidence in the case".. ? Almost nothing. But it's treated as very hard evidence right now! Anybody (hacker, programmer, ex-girlfriend, ex-boyfriend, ex-wife, ex-husband, co-worker in office etc. etc.) could pretend, and wrote something compromising (e.g. utilizing moment of distraction of the device owner).. Smartphone localization? It proves that smartphone was in that location, not owner personally of the device! One could "borrow" smartphone (or even make duplicate of SIM!), then commit crime, and return smartphone to owner who will have no idea about the case...
  5. There is limit how many additional electrons can have atom or molecule. After proton-capture or neutron-capture nucleus can become radioactive, unstable, and decay.
  6. It's called Hydride https://en.wikipedia.org/wiki/Hydride
  7. But such input would cause endless loop, which will be instantly visible..
  8. To make tiny senseful contribution to this thread, I made quickly C/C++ program to generate Collatz Problem sequence integers. Source code is attached in archive. /* * CollatzProblem v1.0 created by Sensei (c) Aug 2018 */ #include <stdio.h> #include <stdlib.h> void CollatzProblem( int value ) { for(;;) { printf( "%d ", value ); if( value == 1 ) break; if( ( value & 0x1 ) == 0 ) { value /= 2; } else { value = value * 3 + 1; } } } int main( int argc, int *argv[] ) { if( argc >= 2 ) { const char *buffer = (const char *) argv[ 1 ]; int value = atoi( buffer ); CollatzProblem( value ); } else { printf( "Usage:\r\nCollatzProblem.exe [value]\r\n" ); } return( 0 ); } CollatzProblem.zip ps. If you want to test also negative integers, add lines: if( value == -1 ) break; if( value == -5 ) break; if( value == -68 ) break;
  9. Force is in Newtons unit. [math]F=k_e\frac{q_1 q_2}{r^2}[/math] Electric field is in V/m unit, or N/C unit: [math]F=q_1 E[/math] [math]E=k_e\frac{q}{r^2}[/math] Vector version of equation: [math]\vec{E(r)}=k_e\frac{q}{r^2}[/math]
  10. Electron is stable particle in Standard Model. Decay of electron has not been observed yet. Did you mean "recombination of electrons and nucleus" (i.e. deionization, capture of electron by nucleus (to form neutral atom)) instead of "decay".. ? If so, electrons are fired in vacuum, with high enough kinetic energy given by electron gun. They must decelerate prior being captured by some nucleus (to form neutral atom). e.g. when highly enough accelerated particle is hitting fluorescent/luminescent screen, there is emitted photon, and particle is decelerating. Photon can be observed. You should read how CRT (Cathode Ray Tube) is designed: https://en.wikipedia.org/wiki/Cathode_ray_tube
  11. What I meant was that if they would continue catching fishes, generation by generation, their brain would evolve bigger and bigger, as evolution would promote individuals with bigger brain, as they would more easily catch prey and have more offspring. BTW, you should compare e.g. eagle brain size with pigeon brain size, etc. at least in the same division of animals. Your examples are not their staple food, just accidental (except sharks and seals). Sharks have bigger brain than seals.
  12. And so what? If apes in Africa would not evolve to humans, they could evolve to "apes v2.0" and later to "humans v2.0".. Japanese monkeys started catching and eating fishes. That's quite good start. Predators require bigger brain to predict behavior of prey. https://www.japantimes.co.jp/news/2016/02/03/national/year-miyazaki-islands-fish-eating-monkeys/
  13. How about extending question to "where did monkey exist, outside of Africa, ...."? Howler monkey and few others in Central and South America.. https://en.wikipedia.org/wiki/New_World_monkey Macaque in North Africa (Morocco) and Asia, including Japan islands.
  14. Yes. Did not I say it in the first post? I made such application (entire network), for steelworks..
  15. In classic physics there is no electron. There is no quantization of charge e=1.6021766*10^-19 C. Classic physics don't deal with particles.. etc. etc.
  16. There are existing such applications. How is that different from e.g. video conference.. ? One smartphone/tablet is recording video from front, back or both cameras, and sending through Internet, to yet another smartphone/desktop/FTP server.. Your application would have to be special with unique features for specific client, to be worthwhile purchase.. ps. Don't waste time on asking these "questions". Better buy C/C++, Java, PHP, Perl, Python books, read them, and learn programming.. During reading and learning you will see what is feasible to be done.
  17. I made something similar for company owned by Arcelor Mittal. Single IR camera (worth $3k each) is monitoring single workplace (with liquid metal), it is connected to mini PC computer (something like Mini Mac, but with Windows installed). There is entire network of such setups in the hall. Software installed on mini-PC is taking screen-shot every second, resizing it to smaller resolution, compressing it, and sending through LAN to central computer, where is control application which joins the all camera screen-shots together on single screen to view by human administrator. Display is refreshed every second.
  18. That reminded me how formula 1 drivers handle it.. They have pipe in helmet and button on steering wheel to release fluid. https://www.youtube.com/watch?v=_d6nu0ofQaA Google for "f1 drinking system" or so.
  19. The keyword is an "international travel". If the cruise ship is not traveling internationally but locally, a passport is not needed. Some countries accept regular id, and passport is not needed. e.g. if you have EU citizenship (any EU country citizenship), you can travel entire Europe, without passport.
  20. There is 3142 isotopes of 118 elements. Majority of them, significant majority, are unstable. Free neutron is also unstable and decays with mean-life ~15 minutes.
  21. Private window mode doesn't store cookies and temporary files (so won't use and overwrite existing settings).
  22. It's in CSV format. Comma-separated values. Plain text file. https://en.wikipedia.org/wiki/Comma-separated_values If you're making script, you can do whatever you like. Make columns and records of data the way you like.
  23. No. It's moderately easy. Just make a PHP, Perl, Python etc. script, which will gather the all data. It's called web scraping/data scraping. https://en.wikipedia.org/wiki/Web_scraping I just found website on which the all US Zip Codes are offered for $15. They offer also software to work together with their database for $20.
  24. No. Such data as city zip codes are available for free.. You just have to GOOGLE it on the Internet... e.g. New York https://www.unitedstateszipcodes.org/ny/ find PIN code in India https://www.indiapost.gov.in/VAS/Pages/findpincode.aspx
  25. Now we have e-Sports, and e-Sports World Championships/Olympics. People in theater, stadium, or home, are seating for hours watching how other people are playing computer games.. http://fortune.com/2018/06/28/esports-olympics-paris-2024-ioc-forum/
