  1. It used to be science forum... I miss that...
  2. Study quantum physics and science.. it will take you closer to the truth for sure.
  3. I know such smart sentence: "spend your time wisely".. Majority of people are wasting their time IMHO.
  4. In classic physics time is 4th dimension (with three spatial dimensions *) ). It allows positioning events or objects on timeline. e.g. position of object e.g. car A and car B is in 3D (xyz) 0,0,0 on parking.. So they would have to overlap without yet another parameter. Add time, and you will have: 0,0,0, today 17:00 and 0,0,0, today 18:00 (one hour difference between them), and objects A & B won't overlap anymore.. *) in some non-classical extensions it might be different number of dimensions than three.

  5. You declared fire parameters at the beginning as arrays: float[] fireX= new float[totalFireNum]; float[] fireY = new float[totalFireNum]; int fireSpeed = 15; float[]fireLeft = new float[ totalFireNum]; float[]fireRight = new float[ totalFireNum]; float[]fireTop = new float[ totalFireNum]; float[]fireBottom = new float[ totalFireNum]; ("fire" is inappropriate name. You rather meant "missile".. ?) but later you're treating them as regular scalar variables... e.g. image(fireShape, fireX, fireY, fireW, fireH); fireX = fireX+fireSpeed; fireRight = fireX + fireW; fireLeft = fireX; fireTop = fireY; fireBottom = fireY+fireH; (addition of float/integer to array pointer (address) ?!) You should make loop going through entire list of missiles, display them one by one, and change their positions independently, incrementing/changing array fields..
  6. Involvement of NATO (not just USA) was direct result of massacres and mass murders.. https://en.wikipedia.org/wiki/List_of_massacres_in_Yugoslavia https://en.wikipedia.org/wiki/NATO_bombing_of_Yugoslavia It was completely unacceptable for world community.
  7. Reason of somebody existence can be told after many years (usually hundreds, thousands etc. from eternal perspective) e.g. without father and mother of Einstein (go deeper and deeper in family tree, searching for older predecessors), he would not be born, and would not be able to influence science.. (and somebody else would have to take his role in other version of the Universe)
  8. In computers there are needed just 0 and 1, bit, to make the all other possible combinations, after using enough of bits together. But it's wise to have checksum, to be able detect damage in code. Damage in DNA is inevitable, simply because of some of radioactive Carbon C-14 will decay to Nitrogen-14, sooner or later: [math]_6^{14}C \rightarrow _7^{14}N + e^- + \bar{v}_e + 156 keV[/math] And such data is destroyed in unpredictable way.
  9. As always, John, you draw conclusions from words that have never been said.. "or other cooled solid substance which is sublimating at room temperature" means it's certainly not liquid Nitrogen.. (liquid Nitrogen is... hmm.. liquid, not solid substance....)
  10. Burning fuel creates various intermediate toxic compounds. But if you would use e.g. dry ice, liquid Nitrogen etc. etc. or other cooled solid substance which is sublimating at room temperature, it could pretend "smoke".. Search Google for "dry ice+water" e.g.
  11. Elementary electric charge e=1.6021766*10^-19 C is measured in oil drop experiment. Electric field created on metal electrodes keeps oil drop levitating (or even moving backward) against gravitation which tries to accelerate oil drop toward Earth. https://en.wikipedia.org/wiki/Oil_drop_experiment
  12. (let's assume that answer for premise "Every particle is an excitation of it's own field?" is yes).. Who said so that they're stable? e.g. Muon- decays to electron (and electron anti-neutrino, and muon-neutrino) e.g. Muon+ decays to positron (and electron neutrino, and muon-anti-neutrino) And this happens extremely fast.. Electron/positron can't decay anymore (at least according to current Standard Model knowledge..), but can e.g. annihilate with its anti-particle. And as a result, different set of particles (and eventually anti-particles) will appear instead. IMHO fields are mathematic models currently used to describe what particles and anti-particles are doing..
  13. That reminds me "zombie-ant fungus" ("Ophiocordyceps unilateralis") https://en.wikipedia.org/wiki/Ophiocordyceps_unilateralis (read Life Cycle at least)
  14. Geostationary orbit.. https://en.wikipedia.org/wiki/Geostationary_orbit
  15. If it just appeared, it could be sign of internal bleeding. e.g. ps. Make photo and attach in reply. It'll be easier to analyze..
  16. Sensei

    E=h*f ?

    Because his understanding of physics is so weak.. ?
  17. 5. Use timelapse in camera to record slowly progressing event e.g. grow of plant. Then glue them together in compositing software to video file. 6. Measure and record solar energy on solar panels entire day. Plug voltmeter and ammeter to solar panels. And record data every e.g. 15 minutes or so (or better set up camera at multi-meters so you will have the all data on video, and then just read them from video file). Enter data to OpenOffice Calc/MS Office Excel, and show on graph with minutes/hour of day in X axis. 7. Make Cloud Chamber. 8. Make Van De Graaff generator.
  18. In Roman Empire rich people were funding and building public baths. https://en.wikipedia.org/wiki/Ancient_Roman_bathing ps. It's better to prevent, in smart way, than having to fight with something when it appears (mostly because of stupidity/incompetence to see in advance).
  19. In quantum physics we're using eV for energy, eV/c^2 for rest-mass, eV*s for angular momentum. 1 eV energy is equal to 1.6021766*10^-19 Joules. (or 1.602176565*10^-19 J in slightly older measurement). ps. Did you mean kilogram-meter-second system? It's SI unit. https://en.wikipedia.org/wiki/SI_base_unit There is slightly older CGS, centimeter-gram-second system. https://en.wikipedia.org/wiki/Centimetre–gram–second_system_of_units
  20. Even Julius Caesar was slave.. he was captured by pirates.. had to pay 50 talents ransom.. "On the way across the Aegean Sea, Caesar was kidnapped by pirates and held prisoner. He maintained an attitude of superiority throughout his captivity. The pirates demanded a ransom of 20 talents of silver, but he insisted that they ask for 50. After the ransom was paid, Caesar raised a fleet, pursued and captured the pirates, and imprisoned them. He had them crucified on his own authority, as he had promised while in captivity—a promise that the pirates had taken as a joke. As a sign of leniency, he first had their throats cut. He was soon called back into military action in Asia, raising a band of auxiliaries to repel an incursion from the east." Economic slaves.. They can't quit unwanted job because of credits, bills, etc. etc. I wish the all people job they love to do.. so they would love to go to work, not hate.. If you love your work, money is not needed as reward.
  21. Plasma is extremely hot. Touch of it can ionize, vaporize regular matter, change state of matter etc. It depends on how much of plasma you have. Significant amount of plasma on Earth in the laboratory, are kept in electromagnetic traps, to disallow touching of walls, which could destroy/damage walls.
  22. 1) who said so there is purpose.. ? If you're creating Universe with certain physical constants you are interested, you are testing, whether they will work or not, and what will be outcome.. 2) human life? what with other terrestrial life forms? what with extraterrestrial life forms? and what with extraterrestrial intelligent life forms.. ? Certainly, life forms that better understand environment in which they exist have higher chance for surviving.. Therefor development of better and better sensors analyzing environment (cells detecting light, monocular, binocular vision, allowing to measure distance to e.g. prey..... ears, detecting sound, then double them to be able tell direction of sound and distance, etc. etc.). Sensors require organ which will analyze the all data, therefore development of brain, and then intelligence to be able analyze data at higher levels.. 3) science is yet another level of environmental analysis by life form, but with mathematical formulas used to describe it 4) quantum physics is the highest level of analyzing the environment by the intelligent life form. ps. You should replace "human" by "intelligent life form" the next time. This way you won't exclude extraterrestrial intelligent life forms from your debates.
  23. You didn't pay enough attention reading my post. What is bad for USA/world, is good for his and colleagues pockets.. They want to have crash on stock markets. If you know when it'll happen, you can set up transactions and earn damn a lot of money on it.. Each time D.T. is appearing in TV every broker of the world has finger on keyboard button, just in case..
  24. There will be economic war. Hit by hit, from each side. Everything what is necessary for them to cause crash on stock markets..
  25. I would do it using electrolysis of copper electrodes. It'll produce bluish color Cu(OH)2, if there is used low/medium voltage. But after overheating it, or using higher voltage, there will be created black CuO and it'll gather at the bottom of tank, as it's insoluble in water. It could also produce traces of Cu2O (especially when there is used high voltage). I made it couple times. But it's easy to spot them and filter as they have reddish color. If something contains Sodium you can check using flame test for Sodium.. https://en.wikipedia.org/wiki/Flame_test
