  1. Beryllium-8 is very unstable isotope. It's decaying to two alpha particles. Or, what is much more probable, you have no idea why they are existing. Existence of Helium-4 is doubtless. You can just ask question- why is it stable. I have calculated hypothetical Decay Energy of a few lighter elements, and every time isotope is stable Decay Energy is negative value. Proton, Deuterium, Helium-3, Helium-4 don't have any hypothetical daughter element which is conserving both energy and electric charge. When element is unstable you have Decay Energy which is higher than 0. Helium-5 has Decay Energy > 0 only for neutron emission (DE<0 for beta decay-, beta decay+ and proton emission). And that's the way this isotope is decaying.
  2. Your conclusions are quite ridiculous. How can scientists explain something that never have been detected? Fleischmann detected unexpected heat. At least that's what they said. We have just their words for it. That's it. Their claim that it must be cold fusion, have as much value as your claim that magnetic moment 0 in Helium leads to existence of aether.. Fleischmann did electrolysis of heavy water in vacuum flask. And instead of 30 C he measured 50 C. I have many times reached 100 C (and have to stop) during electrolysis of normal water, but never thought about it as cold fusion. First question that I would ask- what material is vacuum flask made of. Usually they're made of aluminum. We would have to ask Fleischmann (he is dead now) or his team.. We can easily see that if it's made of aluminum, there will be Al(OH)3 floating in it after a while of electrolysis. The more of it floating, the more current is flowing. I have literally kg of Al(OH)3 (and after removing water Al2O3) created during electrolysis. Another question- what electrolyte was used. Are you saying that f.e. proton doesn't have 938.272 MeV etc. with other particles ? If not, which part of nuclear models you don't agree?
  3. There is no single answer. For Hydrogen you can calculate energy of emitted or absorbed photon with some level of precision. You might want to read about Rydberg formula http://en.wikipedia.org/wiki/Rydberg_formula Personally, I like to use this formula E = 13.6/n^2 - 13.6/m^2 (in electron volts) n >= 1 m >= 2 so f.e. for n=1 and m=2 E=13.6/1-13.6/4 = 10.2 eV E=h*c/wavelength so wavelength = h*c/E so wavelength = 4.135667e-15*299792458/10.2 = 1.2155e-7 m = 121 nm You can put this formula in OpenOffice Spreadsheet, and you will receive something like this:
  4. I am not sure what is your knowledge, so will suggest reading about absorption and spectral lines for beginning. http://en.wikipedia.org/wiki/Spectral_line http://en.wikipedia.org/wiki/Absorption_(electromagnetic_radiation) This video should be also useful for showing different photon-electron-nucleus interactions: https://www.youtube.com/watch?v=4p47RBPiOCo
  5. Smash banana with fork. Then use as filling for normal (i.e. French, flat, no yeasts) pancakes. Roll them. It is superb.
  6. It's in speculations 2nd page. And BlueSpike is author of that thread too.
  7. No. Plasma is causing unpredicted chemical reactions. It's stealing electrons from surrounding it matter. It wants to go back to gaseous state of matter. There must be enough high voltage, or density & temperature, to keep plasma in plasma state. That's not plausible in living organism. I have cascade generator which is "producing" 40,000+ Volts. Once it will create electric arc, or create coronal discharges (especially), we can smell ozone O3. 3 O2 -> 2 O3 (that's example unpredicted chemical reaction. it depends on available matter what will be produced. If you would have 2 L Hydrogen, 1 L Oxygen, water would be plausible). With enough distance between electrodes (or if we will place magnets close to them) ozone can be produced in large quantity even at 11,000 V in coronal discharge (that's appearing as small violet thunders coming mostly from positive electrode. It slowly, slowly goes from one electrode to another, once they unify, there is explosion and discharge of capacitors). Above photos are from ~25 kV. You can't use plasma to keep living organisms flying in skies.
  8. Internal heat of Earth is result of decay of radioactive isotopes that are present inside of Earth, and initial heat of forming planet. It's *finite* source of energy. There is finite quantity of radioactive isotopes, and new one meteorites are rare at this stage of formation of Solar System. At one day they will all change to stable isotopes and no longer release enough energy. Abusing geothermal power would lead to unprecedented results. You have many examples in Solar System of what happens with planets or satellites after losing all heat: Mars or Moon. Lack of energy will change metal liquid core to solid, which would result in lost of magnetic field, which would result in lost of protection against Solar storms, flares, particles with high energy. Which would lead to lost of atmosphere and sudden death of all organisms.
  9. Matter is form of energy. For instance electron/positron has energy 510999 eV. (That's ~220,000 times more than green light photon 532 nm) Proton/antiproton has 938272046 eV (1836.15 times higher than electron). Neutron/antineutron has 939565378 eV. That energy can be released during annihilation of particle. Annihilation (unlike layman think basing mostly on sci-fi movies) is not total disappearing, but changing matter to f.e. gamma photons. For instance positron with electron: e+ + e- -> y + y
  10. Does your camera glass have wifi? What is model name? Do you have Google glass?
  11. For instance - to display name of day of week currently we have to execute following code: int seconds = time(NULL); // input data const char *daynames[] = { "Mon", "Tue", "Wed", .... "Sun" }; int days = seconds / ( 60 * 60 * 24 ); printf( "Today is %s\n", daynames[ ( days + 3 ) % 7 ]; OP postulated extending quantity of days of week:
  12. Sounds like more complications than it's all worth. Especially for software. Timestamp is typically stored as number of seconds since 1970.
  13. Uploading it to FTP? Taking video - but from what source? If it's digital camera, after connecting it through USB there is appearing new removable device with it's own path. So application can monitor that path, to see whether new files appeared, then upload them to remote FTP or copy to local disk and share it in local HTTP or FTP. Mine two digital cameras are locked up when they are connected through USB to computer. And nothing can be done with them until unplugging.
  14. Johnny Electriglide, do you have children? Anybody who in this thread are saying/voted that we are overpopulated- do you have children?
  15. Yes. Nucleus possessing the same electric charge (f.e. positive and positive) will be repelling. Typical human made plasma wants to expand in the all directions in vacuum. Therefore we need to surround it by very strong magnets/electromagnets, which will be pushing plasma from all directions and it won't touch device's walls (that would melt it). http://fire.pppl.gov/KSTAR_First_Plasma_Photos.png Nucleus of matter and nucleus of antimatter will attract. There is even exotic human made matter where antiproton is orbiting for a while Helium-4 nucleus (so role of electron is taken by antiproton). Then after a while antiproton and nucleus are annihilating.
  16. Negative energy, and negative mass, is hypothetical concept. You can read about it here http://en.wikipedia.org/wiki/Negative_mass In whole article about Casimir Effect there is no single mention about "negative energy". There is just about "zero-point energy". http://en.wikipedia.org/wiki/Casimir_effect Do you understand that you're asking about something hypothetical.. ?
  17. IMHO negative energy doesn't exist. In the all calculations energy produced by fission, fusion, pair production etc. etc. we can just see positive energy.
  18. After reaching some threshold compression, matter will change to plasma (nucleus and electrons are free), and nuclear fusion will start up (at least for initial H2O). Water will no longer be water, but mixture of protons and Oxygen nucleus and electrons. But it needs cosmic scale amount of matter to create enough pressure. Some estimate that Jupiter would need 50-75 times of its current mass to ignite and become star. For instance Sun core has density 150 g/cm^3, which is 150 times denser than water density on Earth (and 7.7 times denser than gold 19.3 g/cm^3). Average distance between particles will be much much smaller.
  19. He said "Vacuum gap 10e-9 m Casimir effect" 10e-9 m is 10 nm.
  20. Newsweek article about russian cyber propaganda attacks (use translator to read it). SuperExpress article about the same. First paragraph after translation "Newsweek expressed his concern, because he noticed that every time they publish an article on the situation in Ukraine, in the comments there is a huge amount of anti ukrainian and anti-our nation comments. Quotes are often vulgar and definitely very pro-Russian." Problem is quantity. There is hundred portals. With thousands articles. And each one is commented by them whole day. The most competent are probably concentrating on CNN, BBC and MSN. Less competent are using translator and are easier to notice that something is wrong with them. They need to: - use proxy servers to not reveal their true IP location - register e-mails in western countries - register on forum using above e-mail - knowing language of forum they are writing, or using translator - stay on forum for days, since 1 march, commenting everything especially articles about situation in Crimea and Ukraine. - comments are in the same tone: how good is putin and russia, discrediting Ukraine, condemning sanctions, disparaging war, introducing fear. I will give you examples from today (discussion between Merkel with Obama about escalation of sanctions) Comment about Merkel from above link after translation (google) "Polish Jew should remember that there is no majority in the Bundestag and censure could end her political career. This pederast who was the loudest Russophobe is no longer in the Bundestag, nor his party ..." (Merkel grandparents are Polish if you don't know) Comment from this article: "Bravo President Putin. EU using money from the CIA introduced brothel in Ukraine and now has them in ass - any help (except for installing their agents in the style of a new prime minister or president). In contrast, Putin was the only one still helps Ukraine, crediting its gas supplies to the country. Now you can see where Ukraine has real friends." So our "friend" alkis3 is quite nice person in comparison to what we can find on the other forums.
  21. It's pretext to introduce Internet censorship. Government will tell you which websites are 'right' and which are 'wrong'. As a result all people will have to encode all their traffic and use services such as Tor to hide everything what they do on the net. You can show what you think about such politics in the next elections.
  22. So according to you putin is the only intelligent enough person in your country to have power. That doesn't sound good about your nation. Western countries have many valuable competent people. Lost leader can be instantly replaced. Unlike English people on forum here, I absolute don't have any doubt that you're hired by KGB person to write for money in western medias. In mine country we have genuine flood (or rather tsunami) of people of your kind never observed before. You're paid for writing good about putin and russia. Fight for people minds.
  23. Obama won't be elected 3rd time for presidency. Obama won't be changing constitution to fool people and ruling forever. Obama won't be changing his country to totalitarian country.
  24. You need to understand what is color in the first place. White light are photons with various frequencies in visible range. In wavelengths from 380 nm to 750 nm. When photon hits surface of material, it can be absorbed or absorbed and emitted. Emission can be in different range than absorption f.e. absorb ultraviolet and emit visible light. White surface in white light is white, because all photons are reflected. Pretty none are absorbed. If source of light is not white (some frequencies will be missing), white surface won't appear white to our eyes. If you have red source of light (like in old fashion photographer room), white wall will appear red (wavelengths 380nm to ~600nm are missing). Red surface in white light is red, because red photons (~620nm - 750 nm wavelengths) are reflected from it, and all others are absorbed. Green grass and leafs in white light is green, because green photons (~500 nm... 570 nm wavelengths) are reflected, and all others are absorbed (and used in photosynthesis). Color of material tells us how material reacts to photons with given frequency/wavelength/energy.
  25. No. And no. Energy is in Joules unit. Which is kg * meter^2 * second^-2 1g = 0.001 kg c= 299792458 m/s so E=0.001*299792458^2 = 8.9875517873681764e+13 J To release this energy there would be needed antimatter. Reread what I said in #4 post. Radioactive decay is splitting particle that is initially at rest, to couple particles with high energy-momentum-velocity. It's much easier to see mass-energy equivalence when you know how to calculate released energy (decay energy).
