  1. Don't you like challenges? Going from homeless/immigrant with "$10 in the pocket" to billionaire is harder than going from child of millionaire to billionaire.. (If wealthy is "aim" for somebody. That reminds me son of Buffett who sold Berkshire Hathaway stocks to become musician..) Going from "nobody known school" to f.e. Nobel prize, is more impressive achievement than receiving Nobel prize after Harvard...
  2. I would rather like to make aquarium for either big fishes and small fishes and watch them... Already done
  3. Actually you're looking at this from monotheistic point of view. In Ancient Greek mythology, f.e. god Zeus was created by Cronus and Rhea.
  4. You're simplifying it, or looking from biologist/chemist point of view, instead of physicist. One can make in laboratory ("source 2") f.e. ethanol were every Hydrogen is replaced by Deuterium. C2H5OH -> C2D5OD Chance to find such compound in the nature is extremely small. In the "normal" naturally made ethanol ("source 1") Deuterium will be randomly occurring in this compound.
  5. Nonsense. Revealing couple pretty meaningless details, is completely different thing. So what people know your first name, surname, country, and job? The rest is hidden for "friends". Conversations between parties are secret (or at least should be). If you speak to your friend, partner, business co-worker, investor, privately, you don't want everybody around know about what you're talking about. Making any serious business with BB on the line, is plain ridiculous. Everybody will know that you plan to buy company prior acquisition, or sell stocks prior selling, and set up market accordingly and against you...
  6. That's why I am saying there is needed/required to fly to the Moon, Mars, further planets and colonize entire galaxy.. Introduction of worldwide Big Brother will make even more terrorists, as majority of regular citizens will be against it. Earth's area is 5.1*10^14 m^2, after removing oceans and seas remaining 29% of land, divided by 50B people, is 54.4 x 54.4 meters area per person (currently approximately 145x145 for 7B). Cities, buildings should be already optimized to build as high as possible, to not have to dismount them in the future.. Tower with 55x55 m^2 bottom area, with 100 floors, is reducing 1:100 needed buildings quantity to hold 50B people. Or start thinking how to build below ocean or below ground surface (or even on/in the water).. Which is either doable, as well as, necessary in the future.
  7. If you want healthy sugars/carbohydrates, eat fruits and vegetables..
  8. In 80 kg body there is 1233.333 mol of Carbon. That's 7.43*10^26 atoms. Majority of ancient Romans were cremated after death, including Caesar, Now calculate area of Earth with mean radius 6371000 m = 5.1*10^14 m^2 Divide Carbon atoms in Caesar by area of Earth, 1.456*10^12 Carbon atoms per m^2 of Earth (including air above it). 1.456 mln per mm^2. If dust/CO2 would cover every m^2 area equally.
  9. You have not been in Russia, Alaska, North Canada, Sweden, Finland, Norway or North/South Pole. They have day/night taking up to ~half year. https://en.wikipedia.org/wiki/Polar_night Instead they have Aurora https://en.wikipedia.org/wiki/Aurora Highly accelerated particles from the Sun, and cosmos hitting upper level of atmosphere.
  10. No math = you have no idea what are you talking about..
  11. Then make new e-mail on public server f.e. gmail.. And send it by sms (if security is issue). You can also call number/sms by Skype. If you was in that restaurant, open google maps Heraklion Greece, and find it on the map. Maybe there is mentioned website and e-mail to them. You perhaps made mistake in telephone number, I see they have format +30 xxx yyy zzzz Majority of them +30 281 yyy zzzz Mentioned by your have one digit more (double 2). +30-281-076-1135 belongs to ARINA SAND Restaurant - Tavern - Hani Kokini 715 00 Hani Kokini Heraklion Greece http://www.xo.gr/profile/profile-907385837/en/
  12. If it's Theory of Everything, then please be so kind, and show us, using your equations: fusion, radioactive decay of isotopes, how to make mesons pion, kaon, decay of mesons 2nd and 3rd generations, decay of leptons 2nd and 3rd generations, annihilation etc. Of course you're aware that you can see all these effects by naked eye? http://www.scienceforums.net/topic/92998-universal-evolutionary-process/?p=900023
  13. Not really. Everybody can learn everything. It's just a matter of willingness. You would need some screen-capture application in video mode, and being able to save directly in anim-gif. VirtualDub worked for me on WinXP, but have problems with Win7 (can't capture anymore). Maybe it's gfx driver issue, and you will have more luck. I just tried loading static image-sequence from disk and wrote anim-gif without problem.

    You can do that by using library of common repeated patterns, and using index/id to that array, as stored compressed data. Library can be static and not attached to data, or dynamic and be part of data, or mixture of both. f.e. you have my text reply. Find repeating characters,words in it, and assign the smallest possible number of bits to the most repeatable parts. Normal character is taking 8 bits. If you assign code to the whole word, the whole phrase, you can compress size dozen of times.

  16. I put Hydrogen-1 and Lithium-7 to my command-line application: FusionEnergyCalculator.exe 1 1 3 7 H-1 + Li-7 -> Be-8 + y + 17.2554 MeV H-1 + Li-7 -> Li-8 + e+ + Ve + 0.228274 MeV And it says there could be created photon with 17.2554 MeV. Now see arxiv.org https://arxiv.org/abs/1504.01527 And they say so: "This observation might indicate that, in an intermediate step, a neutral isoscalar particle with a mass of 16.70±0.35 (stat)±0.5 (sys) MeV/c2 and Jπ=1+ was created." 16.7+0.35+0.5 = 17.55, which is almost exactly 17.2554. They used 5 MV Van de Graaff generator, so additional energy comes with higher kinetic energy protons. They don't mention whether they cleaned up isotopes just to Li-7 and O-16. Oxygen has O-16, O-17, O-18 stable isotopes. Lithium has Li-6 and Li-7 stable isotopes. In the case of O-16 its abundance is 99.757%, so there is tiny amount of O-17 and O-18. But in the case of Li, Li-6 has abundance 7.59%. H-1 + Li-6 -> Be-7 + y + 5.60573 MeV H-1 + Li-6 -> Li-7 + e+ + Ve + 5.44562 MeV Beryllium-7 + e- -> Lithium-7 + Ve + 0.861893 MeV
  17. Prism splits photons at various energies/frequencies/wavelengths, so they fly slightly different paths. You can join them together back, and from bunch of red, green, blue photons make white light back. That's what do TV screens all the time.
  18. Proton-rich isotopes can decay by electron capture. And release neutrino (to conserve lepton number). https://en.wikipedia.org/wiki/Electron_capture But daughter isotope (just nucleus) must have smaller mass-energy, than parent isotope (nucleus), to conserve energy properly. In the case of lone proton and electron, there is missing 0.782 MeV mass-energy. Because free neutron has 939.565 MeV/c^2, proton has 938.272 MeV/c^2 and electron has 0.511 MeV/c^2 mass. 938.272 MeV/c^2 + 0.511 MeV/c^2 - 939.565 MeV/c^2 = -0.782 MeV/c^2 Negative means disallowed/missing energy. If it would be >0, such decay mode would be at least plausible.
  19. If you have little container with hole diameter r, therefor it has area A=PI*r^2 (with r=0.5 cm, A=3.14159265*0.5^2=0.7854 cm^2 area) and sound wave is moving (actually air) outside of this hole, room has 400 cm x 500 cm x 275 cm size (20 m^2 floor). Sound wave bounce of the walls. And very very little amount will return back to your hole.. It won't be able to cancel out wave going outside.
  20. This is Adobe Flash, you would need to convert it to Anim GIF.. But voice would be lost.
  21. We will call it Strangeland.. ps. Get island on the southern hemisphere, to be able building telescopes being able observe center of the galaxy.

    Actually, %0111 and %1001 in half-bytes, is %01111001 which is decimal 121, not 113. It's called left-bitwise-shift, arithmetic shift. https://en.wikipedia.org/wiki/Bitwise_operation a=%0111; b=%1001; c=(a<<4) | b; (left-shift a by 4 (=multiplication by 16), then bitwise or b (there is 0 in these bits)) If you add %0111 + %1001 what you will get is %10000, not %1111 (15). If you want to keep result in 4 bits, it should be min(a+b,15), or c=a+b; if( c >= 16 ) c=15; (of course you will lose higher values than 15)
  23. If they're not constant, you should show how they change, and relative to what. Change laws over time? Say we have equation: [math]F=G\frac{Mm}{r^2}[/math] or more precisely [math]F ( r )=G\frac{Mm}{r^2}[/math] It's time-invariant version. Telling how force changes with variable r, distance. But if we assume M and m are changing over time f.e. [math]M(t)=\frac{M_0}{2^{t*a}}[/math] [math]m(t)=\frac{m_0}{2^{t*b}}[/math] (gaining or losing mass by f.e. emitting particles, absorbing particles) where a,b will be some constants (or variables). Then you can make Newton's gravitational force which changes over time: [math]F(t,r)=G\frac{M(t)m(t)}{r^2}[/math] Stars indeed lose their mass, emitting photons, having solar flares etc. But it's so small effect, that while discussion about gravitation, it's ignored. Mass of 1 Hydrogen is 938.272 MeV/c^2+0.511 MeV/c^2=938.783 MeV/c^2 so 4 such have mass 3,755.132 MeV/c^2, but Helium-4 has mass 3,728.4 MeV/c^2. 3,728.4 / 3,755.132 = 1.00717 In other words, if star would fuse the all its Hydrogen-1 to Helium-4, it would lose just 0.72% of initial mass. And it could take 10 billions of years or more. We know about existence of other galaxies, because they emit photons toward us. If laws of physics are significantly different, then how can you see photons from these galaxies?
  24. We can see it, in some circumstances. Air from breath has temperature of body or so. But if environment has significantly lower temperature, we can see something like this: http://media.gettyimages.com/videos/caribou-with-visible-breath-in-cold-weather-looking-around-on-rocks-video-id290-13 Google for "Frosty breath effect","Cold breath effect". After ionization normally colorless gases have different colors (spectral lines) https://upload.wikimedia.org/wikipedia/commons/c/c6/Gase-in-Entladungsroehren.jpg
  25. Non-existence after death is pretty good reason to feel awe. So everybody, especially atheists the most interested, should hard work on how to live as long as possible/forever. Otherwise it's just wasting your precious time here.
