  1. Mass of object on the Earth, is the same as on the Moon. mass m is in kilograms, Weight is m*a=F, force which attracts that mass to center of mass.. acceleration a is different on the Moon than on the Earth, and even on the Earth it's not constant, but variable depending on altitude. Weight is in Newtons = kg*m^2/s. Muscles of astronauts are prepared for Earth's gravitation, to move, or jump, but if the same force of muscles is used on the Moon, they accelerate their body much stronger than on the Earth. They "appear" much stronger, than they really are.

    Router

    I told you what you have to do in #2 post. Every router configuration panel is different. Even same company routers can have different configuration panels. You have to figure out their options. Do you know how to open configuration panel? Did you do it ever? Start from reading router manual. You can search YouTube https://www.youtube.com/results?search_query=configure+wifi+router

    Router

    If your main LAN network is working at IP range f.e. 192.168.0.x, (x=1...255) say 192.168.0.1 is gateway, set WiFi router (after going to WiFi config website) to have gateway 192.168.0.1, and intranet IP range 192.168.1.x, 192.168.1.1 will be intranet IP of router. Newly connected laptop/tablet/device will have assigned dynamic IP in range 192.168.1.2...192.168.1.254 (1 will be router (default gateway on these devices), 255 is used to broadcast).
  4. The first light bulb without vacuum 1802, the first light bulb with vacuum (both platinum) 1840, the first fusion device ~1950..
  5. Regardless of direction in which we look, we see galaxies in early stage of their life.
  6. 32 bit long/int is limited to 32 bits, 64 bit long long is limited to 64 bits, But you can make your own custom integers with "infinite" precision, as much as you have memory in computer. To store 1100 bits there is needed just 138 bytes. Make you own custom C++ class, which is adding/subtracting/multiplying/dividing/and/or/xor/invert/lshift/rshift, or other operations on them. Split calculations to CPU threads (you will learn how to make multi-threading programs) split calculations to GPU threads (you will learn how to make CUDA/OpenCL programs), modern GPU have 1024 cores+, (how much do you have in your GPU?) Statistical will be not precise. There is needed more details to further advice..
  7. By "solid world", do you mean "matter in solid state of matter".. ? https://en.wikipedia.org/wiki/State_of_matter https://en.wikipedia.org/wiki/Solid Solid state matter has very slowly moving particles in lattice.
  8. No, it's not "complete Bullshit" (such argument would not persuade anybody especially "UK lemming"), but it's taking contributions without rebate... and without what is received back.. Manipulation for fools that did not learn mathematics in school.. It's more explained here (for ordinary people): https://fullfact.org/europe/our-eu-membership-fee-55-million/ And here is UK government data for 2015 (for more intelligent people): https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/483344/EU_finances_2015_final_web_09122015.pdf#page=44 In 2015 UK had to pay 17.779 bln, (17.8 bln / 52 weeks = 342 mln/week.. 350 m/w * 52 = 18.2 bln/y pretty close) but get rebate 4.861 bln, which gave net contributions 12.918 bln. After taking into account what EU sent back to UK, it's much smaller. 8.473 bln / 52 w = ~ 163 mln/week It's easy to manipulate these numbers, when it's so hard to calculate it.. And show whatever they want to public. But more intelligent part of population job is to find these manipulations, and show them to public, so ordinary "fool","UK lemming", can understand them easily...
  9. Nigel Farage. the first lemming that jumped off the cliff...
  10. Ehm. UK population is 65,102,385 Voted leave 17,410,742 people 17,410,742 / 65,102,385 = 26.7% (voter turnout was 72.2%.. Pretty good in comparison to ours..) OTOH, fool is just the one who is jumping from the cliff. or also the one who is near to him on top of cliff, and could not persuade him to not do it, in understandable words.. ?

    BRITEX!!!

    What are you talking about? Referendum is not democratic? There is plentiful ways, used especially for this purpose, by winning parties to screw up voting system, in the future elections. To assure the next election will go, the way they want. You have to look closer to voting system details of country to see it. f.e. not linear amount of seats, to amount of votes given on person, or introduction of minimum threshold. Say we have 19 parties, with minimum threshold being 5%, and each of them receive 4.99%, while the all 19*4.99% = 94.81% of people voted on them. And we have one party with 5.01% (with remaining 0.18% invalid votes). These 19 won't get to Parliament, while the one with 5.01% get in, and took 100% of seats... How is that democratic.. ? See who has the largest minimum threshold https://en.wikipedia.org/wiki/Election_threshold russia and turkey... 7 and 10%

    There is plentiful of jobs in the UK, otherwise emigrants would not be able to earn money. But they're nasty, stupefying, not well paid, the one that UK natives do not want. Without emigrants you will have to take them, whether you want or not. Plates in fish&chips must be clean, whether you want or not.
  13. Obviously. Where is no photon, electron, or other particle, there is nothing that can transfer and deliver energy from one place to another (from one particle to other particle). But, In the one frame of reference photon has energy/frequency: [math]E=E_0*(1\pm v_1)*\frac{1}{\sqrt{1-\frac{v_1^2}{c^2}}}[/math] [math]f=f_0*(1\pm v_1)*\frac{1}{\sqrt{1-\frac{v_1^2}{c^2}}}[/math] (Relativistic Doppler effect: redshift/blueshift) In the second frame of reference the same photon could have energy/frequency: [math]E'=E_0*(1\pm v_2)*\frac{1}{\sqrt{1-\frac{v_2^2}{c^2}}}[/math] [math]f'=f_0*(1\pm v_2)*\frac{1}{\sqrt{1-\frac{v_2^2}{c^2}}}[/math] In the third frame of reference the same photon could have energy/frequency: [math]E''=E_0*(1\pm v_3)*\frac{1}{\sqrt{1-\frac{v_3^2}{c^2}}}[/math] [math]f''=f_0*(1\pm v_3)*\frac{1}{\sqrt{1-\frac{v_3^2}{c^2}}}[/math] etc. etc. Who is right, without absolute frame of reference (of some kind).. ? Every observer, looking at the same photon, from different frames of reference, tells completely different energy/frequency/wavelength of the photon.. Property does not change, from different perspectives, charge remain the same, invariant regardless of frame of reference transformation.. In the one frame of reference, there is so much Relativistic Doppler effect blueshift, that there is pair production, and photon is converted to pair of matter-antimatter, in other frame of reference, photon has not enough energy, and there is just Compton effect, or in yet another frame of reference, the same photon is simply "photon in visible spectrum".. Or in extremely redshift, radiowave? In the first case, newly created matter-antimatter, are source of gravity: 1) we can take just their rest-mass into account 2) we take their relativistic-mass, then in what frame? Relativistic FoR will have much more energy thus mass than rest-mass, causing issue while calculating gravity..
  14. Well, there is huge, deistic god won't reveal himself/herself to humans, so scientists can't make any experiment with him/her. To start making experiments, scientist has to have some revelation of phenomena. Humans wouldn't know about magnetism if there would be no natural magnets, and any other way to magnetize objects. Humans wouldn't know about electrostatics if there would be no way to charge objects by rubbing them.
  15. Ihcisphysicist, in other thread, by rejecting antimatter, and annihilation, you showed plentiful of ignorance. I would suggest coming with questions like "how physicists know what they know in quantum physics"/"how to make antimatter","how to check whether particle has positive or negative charge","how to check particle is stable/not stable",etc,etc, then you will learn that you can even see quantum particles on your own eyes in particle detectors like Cloud Chamber.. Prior gathering knowledge restrain from making you own speculations, based mostly on absence of knowledge in area you want to discuss..
  16. Well, if you need 2D graph, you could simply use Open Office/Excel, Make one column input data (f.e. distance) and second column using 1st column as parameter, like A1=0 A2=A1+0.01 Fill down whole column, (so they will be A3=A2+0.01,A4=A3+0.01 etc) B1=1/A1 B2....Bx fill down whole column. Select A and B columns, and Make Graph (or whatever it's called in English version of Open Office). See how it's done here
  17. No, it's not even balanced. Quantity of elements, from left side of equation, must match the one on the right side. If you have f.e. 4H on the left there must be 4H on the right also. Also you should not use =, but -> and should not use -, but +
  18. Pair production does not create matter-antimatter from nothing. Photon with enough energy (at least double energy-mass of what is created), neutral charge, is converted to pair of matter and anti-matter (one with positive charge, other one with negative charge). While annihilation also does not destroy for eternity like you said "obviation". It just converts pair of matter and antimatter to bunch of photons, or other bunch of particles with opposite charges, it's especially complicated while proton-antiproton annihilation. Sum of energy prior reaction is equal to sum of energy post reaction. Sum of charges prior reaction is equal to sum of charges post reaction.
  19. Learn something from this thread how it's calculated: http://www.scienceforums.net/topic/85656-solar-fusion-neutrinos-and-age-of-solar-system/ Annihilation happens only between matter and its antimatter particle. Pair production creates equal two particles of matter and antimatter, with just couple properties like charge, opposite each other.
  20. What?! You are rejecting existence of antimatter and rejecting annihilation?! Annihilation of electron-positron is responsible for 7.64% of energy released during fusion in the Sun.. If you have vacuum pump, cost of building device making pair-production and antimatter to see annihilation on your own eyes, is within couple hundred dollars.
  21. Yes. I just used boric acid and sodium bicarbonate and bubbles of CO2 are instantly visible. Room temperature 25.7 C. Attached photo, taken a few seconds after mixing compounds:
  22. "The two most useful properties of the metal are corrosion resistance and the highest strength-to-density ratio of any metallic element." https://en.wikipedia.org/wiki/Titanium It has nearly twice smaller density than Iron.
  23. On the video you provided he used insulation, but it's inside. Probably some ceramic. Aluminium is just cover. If he would insulate flue, he also would do it from inside, and ceramic wouldn't so easily transport heat to cover.
  24. Apparently programmers made it this way. Send bug report to them. Sun has irradiance ~1367 W/m2 at distance ~ 150 mln km, to surface of Earth arrives ~1050 W/m2 directly at max, but because of scattering there can be measured up to 1120 W/m2. https://en.wikipedia.org/wiki/Solar_irradiance 1367/1120 = just 22% more.
  25. Are you aware that if you open your html in Chrome, you can click "Tools for Programmers" (or so), and it'll highlight on red the all lines which are causing problems.. ? We cannot do it for you, as you didn't provide the whole game, and all resources.. This error happens in line 195, which in my case is this line: secondif = window.eval.call(window,'(function (canvas_img,temp,rootimage) {return '+secondif+';})')(canvas_img,temp,rootimage); Even my Firefox is mentioning which line is guilty, but you have to watch carefully.
