  1. http://jersey.uoregon.edu/elements/Elements.html I recently stumbled upon this link while looking for a good tool to use to help identify elements by spectra, but I noticed some things I didn't quite understand. Why is it that Thorium and Uranium have such a wide ranged emission spectrum while plutonium has a much smaller one. I read that the more electrons and higher shell configurations give more possibilities to emit light, especially if the electrons are in higher shells. Could somebody clarify?
  2. How exactly is physics coming to an end? In the past few years a rumoured invisibility cloak was made by a Canadian company, the Higgs Boson was discovered, a quantum computer capable of factoring 15 was built, and that's nothing. As we our brains evolve to handle more and we research more chances are it will be many many many years or until the end of humanity before we can't research more, and even then we can always improve upon things.
  3. As said before light travels at c, the letter c is a constant. Perhaps you were thinking of frequency?
  4. Recently as I was reading a book concerning Theoretical Dark Matter I came upon a question which bothered me, but I could not find and answer to it. The question is as follows: If Dark Matter and Dark Energy were confirmed would "Dark particles" be added to the standard model? And would Dark Energy be classified as a fifth force? And for the final question: What would become of any Weakly Interacting Massive Particle on the standard model, would a new model be created, or would it just be added? I'm guessing that any particle would be as all other forces are explained by the Standard model, any thoughts would be greatly appreciated/
  5. A.) You mean SQL, sequel is a common mispronuncation. B.) People still do these things, it isn't just cloud computing now C.) Not everything on the internet is a web-app (It sounded sort of like you were saying this) D.) Perhaps I could be of more help if you were more specific? When you say cloud computing it sounds like you mean server hosting.
  6. I am sure some of you have heard of the "Pokemon lavender town theory" in which a certain town in a video game (Original Pokemon) played music that gave people headaches and made them have trouble sleeping (Including me, even before the theory surfaced). In sound file analysis reportedly images spelling things such as "Leave now" were found, is this possible? Also frequencies were around 44kHz on average, I knew anything on the infrasonic level could cause these such things, anybody know if this is truly possible? Here is an image (From somebody on PMC): http://fc02.deviantart.net/fs70/f/2013/209/a/1/something_by_cosmicluigi101-d6fjs0n.png
  7. I apologize for those who have viewed this topic, I posted with little knowledge of the subject at the time and bad wording. When I had said that I meant the design of the supposed commercial reactor.
  8. If you are trying to imply that controlled fusion is not possible you might want to have a chat with Taylor Wilson (A kid who built a fusion reactor), heat is used to overcome EM repulsion. To get energy out of a fusion reactor one would need an area (Possibly a lithium blanket) to absorb the heat energy from the neutron radiation being produced.
  9. Thrust is typically measured in newtons if you want to calculate thrust I suggest looking around here: https://www.grc.nasa.gov/WWW/k-12/airplane/thrsteq.html as there will be plenty of other equations you may want or need.
  10. Both are simply an excitation of particles, fire being a given chemical reaction creating heat and thus exciting the particles around it, electricity being the excitation of electrons or as commonly meant a flow of electrons.
  11. I know, I understand the Calculator and the square root function, I need a function that I can use for Onclick=function() and use the square root I have already tried several
  12. Not at all, I need to use the function in a table, and in a button. But, that would be nice to know how to add it....
  13. I understand the rest of the Calculator and I know HTML + CSS, but I have no idea how to add a sqrt button, can anybody help the code is below the line where I tried is in red: <!DOCTYPE html> <html> <head> <style type="text/css"> input {text-align:center;} table {text-align:center;position:absolute;left:550px;top:150px;} body {background-color:black;} </style> </head> <body> <FORM NAME="Calc"> <TABLE BORDER=4> <TR> <TD> <INPUT TYPE="text" NAME="Input" Size="16"> <br> </td> </tr> <TR> <TD> <INPUT TYPE="button" NAME="one" VALUE=" 1 " OnClick="Calc.Input.value += '1'"> <INPUT TYPE="button" NAME="two" VALUE=" 2 " OnCLick="Calc.Input.value += '2'"> <INPUT TYPE="button" NAME="three" VALUE=" 3 " OnClick="Calc.Input.value += '3'"> <INPUT TYPE="button" NAME="plus" VALUE=" + " OnClick="Calc.Input.value += ' + '"> <br> <INPUT TYPE="button" NAME="four" VALUE=" 4 " OnClick="Calc.Input.value += '4'"> <INPUT TYPE="button" NAME="five" VALUE=" 5 " OnCLick="Calc.Input.value += '5'"> <INPUT TYPE="button" NAME="six" VALUE=" 6 " OnClick="Calc.Input.value += '6'"> <INPUT TYPE="button" NAME="minus" VALUE=" - " OnClick="Calc.Input.value += ' - '"> <br> <INPUT TYPE="button" NAME="seven" VALUE=" 7 " OnClick="Calc.Input.value += '7'"> <INPUT TYPE="button" NAME="eight" VALUE=" 8 " OnCLick="Calc.Input.value += '8'"> <INPUT TYPE="button" NAME="nine" VALUE=" 9 " OnClick="Calc.Input.value += '9'"> <INPUT TYPE="button" NAME="times" VALUE=" x " OnClick="Calc.Input.value += ' * '"> <br> <INPUT TYPE="button" NAME="clear" VALUE=" c " OnClick="Calc.Input.value = ''"> <INPUT TYPE="button" NAME="zero" VALUE=" 0 " OnClick="Calc.Input.value += '0'"> <INPUT TYPE="button" NAME="Enter" VALUE=" = " OnClick="Calc.Input.value = eval(Calc.Input.value)"> <INPUT TYPE="button" NAME="div" VALUE=" / " OnClick="Calc.Input.value += ' / '"> <br> <input type="button" name="sqrt" value="sqrt" OnClick="Calc.input.value += 'sqrt'"> </td> </tr> </table> </form> </p> </body> </html> Also, I am well aware of the math.sqrt(x) function
  14. Classical Physics encompasses a very vast amount of things, basic physics. If you want to learn all of classical physics it will take allot of research and study, but to start with you could ask specific questions. I would definetly recommend learning at least basic physics, I can assure you that you will enjoy it quite a bit. Some tutorials I found by some kid: youtube.com/user/voidprogramming
  15. It would be black holes, the reason earth has gravity is because (In theory of relativity) its large mass warps time and space, a black hole has such a strong force because when this huge star collapses that much matter into such a small area, ALOT of pull would be generated.
