  1. Typical house in EU has power provided U=230 V,I=18 A, P=U*I=230 V*18 A = 4140 W = 4 kW After exceeding Imax fuses are disconnecting.. Better check your maximums before proceeding (even if you're in factory).
  2. C'mon! Then it's not true. Atom is nucleus + electrons. You would have to say "real physical object is made of nucleus/baryons", to reject electrons from being real physical objects. But we're made of electrons that were created (or at least could be) in pair production, while its antiparticle travel somewhere else, or annihilated already..
  3. Didn't I say in #13 post about pair production? [math]\gamma + 1.022 MeV \rightarrow e^+ + e^-[/math] [math]\gamma + 1.876544 GeV \rightarrow p^+ + p^-[/math]
  4. If particle is not "real physical object", then we (clusters of billions of billions particles) are not real either.. Are you suggesting Universe is simulation? It could be. But if it's perfect simulation, then we will never be able to find it out. Suppose so, intelligent life is appearing in the Universe. It's evolving. Learning physics. Creating computers. Making simulation algorithm that has everything included. And in simulation there is happening Big Bang, then stars are forming. They're fusing etc. etc. and finally after billions years of simulation there is appearing intelligent simulated life, and cycle is repeating..
  5. If photon is not real then electron, positron nor any other particle is not real physical object either. Photon can create pair of electron and positron, or any other pair of more massive particle-antiparticle... So, if electron-positron are real physical objects, then photon that created them must be as well real physical object.
  6. Unit of pressure is [math]\frac{N}{m^2}=\frac{kg*m}{s^2*m^2}=\frac{kg}{s^2*m}[/math]
  7. Do you need to use spectroscopy to figure out substance? Or do you just need to figure it out any way possible? Looking at http://en.wikipedia.org/wiki/C8H9NO2 They seem to have significant difference in properties, like melting/boiling points.. Another way that came to my mind is to do spectroscopy of all these known substances from list of possibilities, and compare with what you have unknown.
  8. They don't want you to remove their software. Typical problem... Brute force method is simply find folder and delete it. But this way you won't have registers updated and appropriate Documents & Settings removed. You should probably ask on Sun's support forum. Maybe in newer version they fixed issue.
  9. For $200 you can get pure non-touchable monitor 24" LED... If you wouldn't have money issue, I would suggest Wacom Cintiq Wacom Cintiq 13" HD have not bad price $1000 https://store.wacom.com/us/en/product/DTK1300/ Of course better is 24" version, but also much more expensive: https://store.wacom.com/us/en/product/DTH2400/
  10. Significant quantity of similar charges is easily visible: Not charged (neutral): Do you see on the streets people walking with hairs pointing each one in different direction (other than punks)?
  11. When we're sending command to distant satellite like Voyager, it's arriving after some time [math]t=\frac{d}{c}[/math] (d - distance). And satellite is returning result after yet another time t, giving total delay between sending and receiving answer 2*t. Astronauts that landed on the Moon had delay 2*1.21=2.42 to 2*1.35=2.7 seconds. When speaker talked with them, their answers were arriving with such delay.
  12. Press ctrl-alt-del and check out in Task Manager how much memory is consumed during playing video.. On WinXP after booting system and opening Firefox and starting browsing net (3 tabs) memory usage is already 987 MB = ~1 GB almost.
  13. Correct. My new application for chemistry is also showing it's good answer, see:
  14. Chemistry Lab Guru application (turn Full HD mode)

  15. Which companies ordered, received eCat, and are using it right now for energy production.. ?
  16. It's not PHOTO. It's 3D computer rendering visualization....
  17. Actually it's not me, but my applications that I wrote.. I am just entering data to applications showing fusion and decay energy calculations, and they're showing result for me (and copy'n'paste to posts)..
  18. That's simply not true. Annihilation of proton-antiproton paths are listed below: Total energy prior annihilation is equal total energy after annihilation. Antimatter (antiprotons) are in plasma state when we're creating them in particle accelerators. They don't have positrons (yet).
  19. [math]\frac{V_1*p_1}{T}=\frac{V_2*p_2}{T}, T=const[/math] When you will decrease volume (f.e. close one end syringe and push it), you will increase pressure inside. In other case: [math]\frac{V_1*p}{T_1}=\frac{V_2*p}{T_2}, p=const[/math] This simplifies to: [math]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/math] But both volume and temperature has to change at the same time, to have constant pressure.
  20. For your purposes Arguslab should be fine. Remember we're talking about situation with hundreds or thousands atoms. I wouldn't call it buggy - it's simply not using higher version API, but lower. Bug is behaving abnormally, or crashing application, disallowing any usage.
  21. It means decrease volume, with const temperature.
  22. Yeah. Algorithm parsing Latex should tell at which character (offset) it failed at least, not to mention full description of reason of failing.. When it happens to me, I am splitting long equation to two, or more. Then part that's wrong is again showing up in Preview Post as "Latex error", while good one is showing correctly. Then repeat it with smaller parts, until reason of failure is obvious. This is typical method of finding error in source code while developing software, when we don't/can't use debugger.
  23. See this old thread http://www.scienceforums.net/topic/83245-a-question-on-radioactive-decay/#entry806204 I am showing how to set up OpenOffice SpreadSheet for decay rate equation.
  24. Dr.Evil who is afraid of getting into trouble. LOL. First of all: aquariums, lot of them, different sizes. Second: gold, you will be able to electrolysis water to raw Hydrogen and Oxygen. When you will have aquarium f.e. 25 L with water, and inside 2 smaller aquariums up-side-down (filled with water). First one electrode will produce Hydrogen, second one electrode will produce Oxygen. And aquariums can be used to store them. While using AC 230 V, after rectifying it to pulsing DC 230 V, you can get something like 0.66 L of Hydrogen, and 0.33 L of Oxygen in 10 hours. The smaller voltage, the higher you have area of electrodes and shorter distances between them to have equivalent result, so alternative to high-voltage is a lot of gold.. I think electricity is cheaper. I paid 50 usd for 1 gram of gold the last time at retail. You need double that for a start to avoid reactions. Then you can attach 2nd electrodes to it, going through water, to where is gas (seriously insulated). Plug electrodes to Cockcroft-Walton high voltage generator (hundred electrolytic capacitors connected in setup with rectifying diodes on breadboard), And you will make Hydrogen/Oxygen plasma in gas in these aquariums. Oxygen-Nitrogen plasma looks like this: When you will manage to prevent creation of plasma you can have permanent coronal discharge: (these photos were taken with 25,000 volts IIRC) Of course you know how to produce nitric acid using setup above mentioned (Cavendish method)? ps. 24 carat gold of course... 14 carat has just 58% of gold..
  25. After pair production, it won't be photon anymore, but particle at its antiparticle (or shower of them). But they have concentrated mass, and high kinetic energy. The highest energy photons ever detected: http://en.wikipedia.org/wiki/Ultra-high-energy_gamma_ray The highest kinetic energy believed to be proton ever detected: http://en.wikipedia.org/wiki/Oh-My-God_particle http://en.wikipedia.org/wiki/Ultra-high-energy_cosmic_ray
