In the basic manual PDF of my country patent office (Google translate): "The principle is that the [country] legal person or [country] citizens having a resident on [country] territory can make patent applications abroad after prior notification to the Patent Office or through the Office (the notifications under international and European)." If it's the same in your country, you cannot skip Turkish patent office, and go directly to U.S. patent office. Anyway why would you like to go such route? Take European or Worldwide patent instead of just U.S. only.. Worldwide cost is ~ 3100 euros for a start in the first 30 days (part in local currency, part in CHF, part in euros, I joined them together).. Better you be millionaire already... Later will be further payments, if patent will be not rejected.. ps. What patent has to do with "creating something great in science"... ? You cannot patent science discoveries.. You could only patent novel usage for already known science discovery. ps2. PCT – The International Patent System http://www.wipo.int/pct/en/

I am sorry to hear about your lost.. Does it have some odor? Nitric and Hydrochloric have odor, at least in larger concentrations. Sulfuric is odorless. If acid has significantly different density than water, you could measure volume, measure mass, calculate density, and calculate how much do you have it. If there is 0% of acid, density is close to water density 1 g/mL, if there is 100% of acid, density is close to mentioned on wikipedia website of acid. If you have density larger than density on website of acid, you can safely exclude it. Like f.e. 1.8 g/mL, it can't be neither Nitric nor Hydrochloric, as they have smaller max densities. On f.e. https://en.wikipedia.org/wiki/Hydrochloric_acid https://en.wikipedia.org/wiki/Sulfuric_acid there are tables showing how density varies with concentration. f.e. table on HCl mentioned density 1189 g/L 1189 g * 38% (by mass) = 451.82 g 451.82 g / 36.46 g/mol = 12.39 mol/L (and you see it's matching table data)

But that's exactly reverse direction from "saving energy".. See wire plugged to bottom? It's turning on electromagnet.. http://design-milk.com/lyfe-emits-magnetic-appeal-levitating-garden/?utm_campaign=trueAnthem:+Trending+Content&utm_content=5779ff2104d30136f4130b18&utm_medium=trueAnthem&utm_source=twitter

Sorry, but saying that Python is way to go, is plain.. ridiculous... Try writing the same routine, doing heavy mathematical equation billion of times, in C/C++ and Python. Place printf( "Clock %d\n", clock() ); at the beginning and at the end of routine (and Python equivalent one). Measuring time in C/C++ http://www.cplusplus.com/reference/ctime/clock/ If you divide ((float)( clock() - t ) / quantity of internal loop execution/CLOCKS_PER_SEC), there is time spend on single loop execution. What do you see if you compare the same code written in C/C++ and Python.. ? Python is interpreter, while C/C++ compiler producing machine code.. Python is written in C/C++! DevilSolution, have you tried Managed C++ ? It's .NET Framework with C++. That's the way, I am writing apps for Windows ATM, GUI is designed in .NET form designer (Visual Studio/Express GUI designer), it's quite user/programmer friendly, and code is still in C++. Why do you want to bother with QT? It has to be working on Linux/Unix also.. ? We would need to know more about your code, how often do you call external DLLs and what they are, to advice better, though.. DLLs are written in C/C++, their interfaces are in C/C++, if you will use other language than C/C++, you will have to use wrappers whether you want or not, no choice. Truly extensive math calculation should be split to various threads/cores of CPU, it can give you 8 times speed up on Core i7, and if it's not enough, there should be rethinked idea of using GPU 1024+ cores (OpenCL/CUDA) for even more optimized code. Depending how long your calculations are taking..

Most efficient method for learning to touchtype?
Sensei replied to StringJunky's topic in The Lounge
Apparently you don't type much every single day. I am writing probably 1000 times more than speaking in the real world, so have problems expressing myself while talking in the real world. I would faster write something on the computer screen, than talk. 30 years of experience.. -
There are couple states of matter: solid, liquid, gas, and plasma. Plasma has lonely protons, and lonely electrons. To turn gas to plasma, there is needed energy from external source (or extreme pressure like in star). For Hydrogen it's 13.6 eV per single atom. Plasma emits photons, acquire electron, and turns to electric neutral gas, neutral gas emits more energy (photons at lower energies), and cool down to liquid, then further to solid. "Extreme high temperatures" mentioned by you, keeps plasma in plasma state, to not turn it to other states of matter, and suddenly to solid state of matter.

In what circumstances proton would emit gluons, and decrease its quantity? And in what circumstances proton would absorb gluons, and increase its quantity? If quantity of emitted particles will be equal to absorbed, it'll be in equilibrium. But if that would happen in different gravitational field, then experiments like Pound-Rebka should be affected, no? Object at higher altitude, will emit particles, but won't get enough of them back. It could be extended to: - what is rate of emitting particles (per second?) - what is rate of absorbing particles (per second?) If it's in seconds, then they obviously in different gravitation, will have slightly different rates, isn't?
-
Well, you should start from learning about gravitational redshift http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/gratim.html https://en.wikipedia.org/wiki/Gravitational_redshift and Pound-Rebka experiment / Harvard Tower Experiment https://en.wikipedia.org/wiki/Pound-Rebka_experiment As these are experiments showing what happens with photons due to gravitation.

In 3D geometry editor you could try bevel tool (or extrude/extender with move tool), select polygon, or couple polygons. but instead of making "positive" mesh, try opposite direction, then repeat it couple times. Make the same method branches. The same method could be used to make tree (but offset positive). Alternative method: make cave mesh, and subtract one object from other object, boolean operation on 2 meshes.

If YouTube video has enabled ads, each 1000 views (approximately), gives $1 income in ads, so 1 mln views will give approximately $1k income (as long as enough and exceed threshold set by user). Basically Google pays video owner each month. As long as it has viewers interested to watch it. Something unusual, interesting, has large viewer count.
-
I would like to see it. Please provide photos. Or maybe even better make YouTube video? 1 mln view count = ~$1k earned Should be enough encouragement to perform experiment in the front of camera.. ? What is purpose of "filtering Aluminium"? Because OP wants to have Sodium metallic, if you didn't notice..

The gravitons are in the atmosphere[exosphere].
Sensei replied to johnny2710's topic in Speculations
And where would that constant being used? In which equation? What units? How could heavier object (entire galaxy) rotating around lighter object (solar system).. ? -
Whether something is stationary or not, depends on FoR you choose.

2 particles input, 1 particle output? Very unlikely, as it would not most likely conserve momentum. 2 particles input, 2 particles output? Yes. It will work.

Even if he would pass chlorine through methane, he would get "unholy mess of different things", CH3Cl, CH2Cl2, CHCl3, CCl4... Reaction with the more details is mentioned on website of CH2Cl2 https://en.wikipedia.org/wiki/Dichloromethane "DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. In this way, an estimated 400,000 tons were produced in the US, Europe, and Japan in 1993.[10] CH4 + Cl2 → CH3Cl + HCl CH3Cl + Cl2 → CH2Cl2 + HCl CH2Cl2 + Cl2 → CHCl3 + HCl CHCl3 + Cl2 → CCl4 + HCl The output of these processes is a mixture of chloromethane, dichloromethane, chloroform, and carbon tetrachloride. These compounds are separated by distillation. DCM was first prepared in 1839 by the French chemist Henri Victor Regnault (1810–1878), who isolated it from a mixture of chloromethane and chlorine that had been exposed to sunlight.[12]"

Gamma photon is absorbed by particle, and f.e. two new photons with lower energies are emitted. Or gamma photon is absorbed by particle, particle accelerated, and new lower energy photon is emitted. It's cascade like effect. 1 MeV gamma photon could be after 20+ such interactions be split to 1 million photons with 1 eV energy each. See Compton scattering f.e. https://en.wikipedia.org/wiki/Compton_scattering

?? Without velocity vector you don't know whether do redshift or blueshift.. Imagine situation: the Sun is emitting highly accelerated electron, or other elementary particle, say it has v=0.5c relativistic velocity, And then a while later the Sun is emitting photon, once photon reaches particle, we have to use redshift calculation to be able predict how particle behaved. Now imagine two binary star system, particle from 1st star is emitted toward 2nd star in system, and approaching emitted by this star photon, then we have to use blueshift calculation to be able predict how particle behaved.
-
Whether it will have more or less energy depends on velocity vector direction. Particle traveling in direction of incoming photon has blueshift Relativistic Doppler effect, [math]f=f_0*\sqrt{\frac{1+v}{1-v}}=f_0*(1+v)*\gamma[/math] while particle travel in the same direction as photon has redshift Relativistic Doppler effect. [math]f=f_0*\sqrt{\frac{1-v}{1+v}}=f_0*(1-v)*\gamma[/math]

I have it right now, and even did this reaction this week.. If you add NaOH + Al + H2O there is created Sodium Aluminate, and Hydrogen gas.. https://en.wikipedia.org/wiki/Sodium_aluminate 2 Al + 2 NaOH + 2 H2O → 2 NaAlO2 + 3 H2 According to Safety page of https://en.wikipedia.org/wiki/Sodium_hydroxide 2 Al + 6 NaOH → 3 H2 + 2 Na3AlO3 2 Al + 2 NaOH + 2 H2O → 3 H2 + 2 NaAlO2 2 Al + 2 NaOH + 6 H2O → 3 H2 + 2 NaAl(OH)4

Heat capacity? Specific heat? https://en.wikipedia.org/wiki/Heat_capacity

Calculation of energy released by fusion, is the same as while calculating decay energy. Sum masses of the all input particles, sum masses of the all output particles, Subtract output from input, multiply them by c^2, and you have energy released.
-
It's different than you think.. Energy released by decay of unstable particle/isotope is calculated like I showed in my signature. Take for example alpha decay. Prior decay we have parent isotope with mass m0. Post decay we have daughter isotope with mass m1. Mass of alpha particle is mhelium. Energy released during decay is E=(m0-m1-mhelium)*c^2 If decay energy is less than 0, spontaneous alpha decay is prohibited! Decay energy is "split" to daughter isotope as kinetic energy of particle, alpha particle as kinetic energy of particle, and optionally to some gamma photons. Decay energy from unstable isotopes rarely exceeds 5 MeV. It's 500,000 times more.

Infinite stupidity, does it count also.. ? Which one for instance.. ? How do you dare to call yourself per "scientist" if you have not taken "physics class in your life"... ? Scientific theory is based on observations. For instance, object fail from height h, in time t. Repeat observation couple times, with scale and stopwatch, to gather data, analyze data, to derive equation: h = 1/2*g*t^2 (g=9.81 m/s^2) The next time something will fail from different height, in different time, you can tell them in advance, how long (time) object will be traveling (if height is known), or how far it will be traveling (if time is known). 1) observation of phenomena 2) gathering data 3) analyze data 4) make equation 5) check equation in practice with more data to check whether it's universal

Quantum mechanics is more about "probability of finding particle in given position/volume +- some tolerance".. f.e. probability to find electron in atom. Quantum physics is how particles behave after emitting photons, absorbing photons, decaying atoms, decaying unstable particles, fusion, fission etc. etc. These things happens all the time, around you, especially in day, when primary cosmic rays (from the Sun), and secondary cosmic rays, are getting through Earth's atmosphere.. You can even see them, in devices like Cloud Chamber. If somebody would write simulator of the Universe, you wouldn't be able to find difference between them. Only if it has errors. If you would be able to find difference, you would have to first know how the real Universe is behaving (how could you know it, in the first place, If all the memories from before birth are gone.. ?), If you would know "how the real Universe is behaving" and "how this Universe is behaving", you would know, you're just part of simulation (or not). Computer graphic designers often make a contents: there is few pictures showed, and people have to tell which is CG gfx, man/computer made, and which is photo. How do you recognize difference? Because of differences from natural environment. CG gfx is too clean, too nice, little detail. So suppose so, "the best CG artist" is making gfx which is not clean, dirty, with details. (I have participated a few such contents, and the real CG gfx artists were better recognizing CG from photo than me, even though I have quite good experience in this ) How do you recognize difference.. ?
