  1. If you're wondering what, you can see: https://www.youtube.com/watch?v=rCHX8QU3cLI Intros like this, are highly compressed. The first loader is called, which is decompressing the real intro code. Then executed. Typically code is generating procedural fractals, and procedural textures, which are used to generate 3D image. Best Regards!
  2. What I advice everybody talking about magnetism is buying compass array device, like below one. I just took photo: It's 2D version (there are also 3D version were magnetic arrows can spin in either axis, not just one axis) You could place permanent/electro magnet on the one side, then some material, which you examine to shield against magnetic field created by magnet, and on other side compass array. Compare results obtained with and without shielding material between them.
  3. I would start from checking units whether they match. Electric field is in Volts/m, Energy density is in J/m^3, etc. etc.
  4. I have a lot of experience with screen recording software, as I recorded over 200 such videos (with repetitions perhaps 400-500 at least), but on Windows. I am currently using VirtualDub http://www.virtualdub.org with Lagarith Lossless Video Codec http://lags.leetcode.net/codec.html It has pretty good rate of compression. During recording the first time, it's recommended to record to lossless file format, as mentioned Lagarith, because if you will encode in lossy file format, and start editing it, cutting start, end, cutting parts in middle etc. etc. You will have double time encode it in lossy file format, introducing double amount of errors in video. Lossy file format, with small size, large compression, require a lot of CPU power to process data. If CPU is extensively used by application we're trying to record, the less is for recording software. And introduction of errors, skipped frames, jumps, possible in extreme situation. Using completely uncompressed lossless file format is also not good idea, as Full HD 1920x1080 32 bit with 30 FPS has to write to disk ~250 MB data per second. Causing problems by write speed of hard disk. Camtasia is another product for capturing https://www.techsmith.com/camtasia.html TechSmith (producent of Camtasia) also recommend to encode original data in lossless file format, and even created and provided their own proprietary lossless codec Described with details on.. Movavi page: http://www.movavi.com/codec/TSCC.html then after editing, save in target file format. IIRC, Vimeo accepted video encoded with Lagarith codec, but YouTube didn't, the last time I checked. They have their own lossy proprietary file formats used to store data on their servers. So uploading twice compressed-decompressed video already, would end up being triple time decoded-encoded, creating even more errors..
  5. You're probably mixing word "weight" with "mass". Weight is force: W=m*g https://en.wikipedia.org/wiki/Weight In unit Newtons. While mass is in unit kilograms. https://en.wikipedia.org/wiki/Mass g changes with distance to object creating gravitation: g=G*M/r^2 Gravitational force on the Moon caused by Earth (r=~384,000,000 m) (or Sun r=~150*10^9 m) is meaningless, as majority of force is caused by the Moon's mass (with r equal radius of the Moon). Meaningless, doesn't mean not existing. That's why there are tides caused by the Moon, and tides caused by the Sun. https://en.wikipedia.org/wiki/Tide Astronaut, on the Moon, will be able to jump much further, than on the Earth, using the same force created by his legs/body. Different result in length of jump. (Jumping on asteroid is not advised, as you can fly away, and never be able to come back, unless you have jet pack) You can find distance from Earth to Moon, or Earth to Sun, or any other object, where force created by one object cancels perfectly with force created by other object.
  6. On his photo I see P2O5, not P2O2. Niha afzal, do you realize there is rotate option in the Paint and even Windows image viewer.. Rotate it 90 degree, the next time, so we will have easier to read your papers. Thank you. Mass of molecule is approximately sum of masses of each element in molecule. Mole of P has ~31 g/mol Mole of O has ~16 g/mol So 31*2+16*5=~ 142 g/mol for whole P2O5 Percentage/fraction of P in P2O5 is 31*2/142=0.43 (43%) (you used 42.6, as far as I can see on the photo. It should be 43.64) This is what would be if 100% of fertilizer would be P2O5. But you have just 30%. So you have to multiply 0.4364 by 0.3 = ~0.131
  7. Have you heard about polarization by reflection.. ? https://en.wikipedia.org/wiki/Brewster's_angle Very easy to see if you have polarization filter. Point it at f.e. flat water surface, and start spinning polarization filter at hand. Reflection will disappear at right angle of polarization filter. Also while passing through some transparent materials, when there is present external magnetic field, there could happen Faraday polarization rotation. https://en.wikipedia.org/wiki/Faraday_effect https://en.wikipedia.org/wiki/Faraday_rotator
  8. Per capita income, is average income. If you have 1 mln people earning $1, and 1 person earning $1 mln, Their total earnings is 1*1000000+1000000 = 2 mln. But quantity of people is 1000001. 2 mln / 1000001 = 1.999998 per capita income. At the same time, median would be $1, as extremities are ruled out.
  9. Algorithm should go through all figures white and black, and check whether they have direct hit at some opponent figure. And mention it. It's done by virtual moving each figure to all positions they can move theoretically. That would be a good start. If you would do it recursively, unlimited times, multi-threaded, you have almost entire AI of chess player. Without time limit such algorithm would calculate all possibilities of movements in the future, either side of game, and their results, trying to pick up the best one from these possibilities. You move pawn, and computer know the all ways to give you checkmate, 100+ moves ahead..
  10. Professional players analyze games after fact to learn where they made mistake, to not repeat them in the future. "Learn from mistake" (especially other people mistake).
  11. With a bit of luck you could win this game, if you would kill tower (or force it to move), white King would have nowhere to escape as he was trapped by pawns. Just move Queen to 1st row, when there is no tower there and done..
  12. You lost because you made plentiful senseless movements like f.e. this 19. c5... And immediately lost tower.. You could move King to Kg7. Whole concept of attack would be broken as it was on the left side of chessboard.
  13. Light from the Sun follows inverse square law. https://en.wikipedia.org/wiki/Inverse-square_law Every double increase of distance, means power, energy, quantity of photons drop to 25%. It's in primary units divided by meter square. So size of object reflecting photons has also influence whether it will be visible. 100 meters diameter rock has approximately PI*50^2 area in direction of Sun. Reflected photons also follow inverse square law in this case, So actually we have two distances: one from Sun to object, then from object to current location of Earth (changing day by day). You can look at other, visible objects, around the one you're searching for, for anomalies in their trajectories. If path is slightly different than expected, there has to be gravitational source somewhere changing their path.
  14. Cosmic objects can be found by: - if they are emitting their own light at visible range, like star. - if they are emitting their own light at invisible range, because of temperature. - if they have tremendous gravitational force to surrounding it objects, like black hole (but it must be surrounded by some object in the first place!) - if they bend (or absorb) light emitted by object behind it. - if they reflect light emitted by other object (planet is visible because light from the Sun is reflected by it). Actually it's the same as with any ordinary Earth object/particle..
  15. Print HTTP headers in PHP, or so, f.e. http://php.net/manual/en/function.getallheaders.php when mobile goes to your website, and when computer goes to your website. And learn what are differences between requests.
  16. PI constant/variable should be used later in code somewhere (otherwise it's unused variable), f.e. for drawing circle on screen, making sphere 3D mesh, calculating area of circle, area of sphere, volume of sphere. If wrong constant value will be used in them, then their results will be also wrong by 3.14159265/3 = 1.0471975511965977461542144610932 (nearly 5% difference). In C/C++ PI is defined in math.h as M_PI. And it should be used in the all programs needing PI somewhere.
  17. So you are in the same situation as 3/4 or 4/5 of the entire population of the world.
  18. f.e. https://en.wikipedia.org/wiki/Oil_drop_experiment "This remains controversial since papers found after Fletcher's death describe events in which Millikan coerced Fletcher into relinquishing authorship as a condition for receiving his PhD.[3][4] In return, Millikan used his influence in support of Fletcher's career at Bell Labs." If such things happens between knowing each other teacher and student, you can imagine situation between famous professor versus "nobody".. How about Newton vs Hooke? They were claiming each other stole their ideas. In older times when the only way of communication was paper mail, XVI-XIX century, one scientist were sending two mails, to his opponent and second copy to himself (and never open), proving that ideas were really sent to person at certain time. Just in case.. Chriss, I doubt you hypothesis have any meaningful value, worth keeping in secret. It's not design of f.e. engine, that you could patent and make money on it..
  19. Maybe it's IQ per race, or IQ per sex.. etc. https://en.wikipedia.org/wiki/Race_and_intelligence But first he has to get database, to analyze it, and verify whether hypothesis is confirmed or overthrow. It would be unprofessional to reveal hypothesis, without even analyze any data, don't you think?
  20. Why having a child is such freaking tragedy.. ? "Unlucky"?! I think it's great to have kids. Somebody would love to have kids but cannot.
  21. Does it help? https://en.wikipedia.org/wiki/Overpotential https://en.wikipedia.org/wiki/Electrocatalyst

    Socialism

    Actually, it could be also interpreted as their attitude for "running for money" (or "running for power" for politics, or "running for famous" for artists etc).. First group is very horny for money, therefor work hard to be successful (greedy for money/power/famous/etc). You would verify their attitude by telling the first and second group that they will not get any reward for what they do, and see what happens... To which group you would classify monks, hermits?

    Socialism

    People need jobs tasks to do. To fill their time, and life. The better quality tasks, the more valuable for community, the better. Jobless person, in capitalistic country, desperately needing money, probably will be all happy to get f.e. warehouseman job, picker job etc. When such stultifying jobs, could be done by robots quite efficiently. Amazon warehouse robots https://www.youtube.com/watch?v=quWFjS3Ci7A It's hard to find people good, valuable tasks. It has all start in primary school, college, and university (or lack of them). Kids since their early days are split to better one, having money for good education, and worser, not being able even to send kids to college. And their parents every day are struggling with life, because of lack of money. "Bankrupting" every week. All because of money, in capitalistic country, constant run for money.. That's nothing else than bits on computer disks. Do you run for virtual credits in games? I don't think so. If one would run "script" to add each bank's account owner +1 bln usd, the next day, every body would quit their jobs.. And whole economy would collapse. People should have such jobs that even after receiving their +1 bln usd, they would go to their jobs, the next day. They should love their jobs, not because they get money for it. When it's done, there is no need for money anymore, as everybody do their responsibilities, without being forced to do them. Producers are terrified by 3D printers. One could model anything on computer, and press button, and thing which they would normally have to go and buy in shop, is done within minutes. If everybody would have 3D printer in home, the most of producers would bankrupt, or have to switch to making highly sophisticated products, above range of 3D printers. Making even more jobless low educated people, that are hired now to press buttons in the real extruder, packing, advertising, selling. But 3D printers producers would be improving their products, to higher resolutions, to limitless materials used for printing etc. One could even make 3D printer next gen, with 3D printer older gen, at home.. ps. That's just ramble about capitalistic country approach, rather than socialism..
  24. No it wouldn't. The difference in mass from losing or adding an electron or two, as JC points out, is tiny. Where did you get this "one or two electrons"? On one side we have F=qE on other side we have F=mg For q=e=1.602176565*10^-19 C (one mentioned by you electron) mg=eE / e E=mg/e for m=10 mg (I am guessing.. what mass might have single oil drop?) so E=10^-5 kg * 9.81 m/s^2 / 1.602176565*10^-19 C = 6.1229*10^14 V/m Don't you think so it's quite too much? The more ionized atoms (the larger q in equation), by x-ray, the smaller electric field needed to cancel out gravitational force. While performing experiment, it can't ionize all medium between electrodes. It would ruin experiment, discharge electrodes. Reasonable workable voltage is probably around a few thousands volts between plates. Adjust q for it. Going back to the main subject. How about this one: if electron mass would not contribute to gravitation, then unstable isotopes decaying by beta decay plus, double beta decay plus, beta decay minus, double beta decay minus, prior decay mass of atom contribute to overall mass of Earth, and failing object, and after decay would not, making Earth, or object less massive than prior decay?! IMHO absurd. Either prior decay and after decay mass of Earth, or other object remain the same, unless electron (or other particle) escape it (like (anti)neutrinos).
  25. Not exactly. Oil drop experiment, https://en.wikipedia.org/wiki/Oil_drop_experiment ionize oil drop, rip off electrons from oil drop, get rid of them. If you have oil drop prior ripping off its electrons, having the same gravitational mass, as after ripping off, it would be revealed in this experiment. Why do you mention G being different.. ? If gravitational mass is changed, it must be changed for either object failing down, and mass of Earth, at the same time. G constant is not affected. F=G*m*M/r^2 after subtracting some mass from either m, and M, G could (should) remain the same.
