Your depiction how science works is flawed. Experimental scientist is making experiments (can be random accident), discovering something, making equations allowing further predictions, and sharing with the rest of science community. Science community is reproducing experiment, and after confirming observation, it's becoming part of knowledge learned in universities and schools. That's why it's important to make experiments, to not lose healthy look (which happens to pure theoretic scientist I am afraid. And they're starting making bizarre theories. It's easy to spot them, as they are not based on experiments). But you didn't presented us your theory. There is no physics theory without math equations allowing to calculate and predict future/past.

Classical observation-measurement can also change state of thing we measure. Take for example thermometer. Mercury metal is absorbing energy and changing its volume, what we're reading on scale. Object that we measured lost that energy and mercury will never return it after end of measurement. The more massive object we measure, the smaller disturbance. Measuring temperature of 1 ug of water, will cause different disturbance than measuring 1000 g of water by the same thermometer. To measure mass we have to stop moving thing = then we are losing its momentum and velocity. After stopping it, it's in the same frame of reference as we with our weighting scale.

Hello! I was searching for what new apparatus to buy and found device for Franck–Hertz experiment for 700 usd. http://www.sci-supply.com/Franck-Hertz-Experiment-p/ss20801.htm If you're not familiar with experiment you can read details here http://en.wikipedia.org/wiki/Franck%E2%80%93Hertz_experiment Basically: accelerated electron loses its kinetic energy of 4.9 eV and excites mercury atom, which is then emitting 4.9 eV UV photon. Video on YouTube showing experiment https://www.youtube.com/watch?v=W0GqNtsmaYU Best Regards! ps. They also have a lot of other interesting stuff.. Oil drop experiment apparatus just $430. http://www.sci-supply.com/Millikan-Oil-Drop-Apparatus-p/ss2438.htm Van De Graaff generator 250 kV for $220 http://www.sci-supply.com/Van-De-Graaff-Generator-250KV-p/ss2311.htm Anybody can afford it (especially scientist interested in quantum physics)..

Inability of calculation doesn't guarantee something is true or false. It's lack of data to calculate/measure. This is similar problem as with flying in airplane without windows with constant velocity (assuming no sound of engines etc) (so we don't have acceleration). What speed it has? Is it flying or waiting in queue on the ground? One would say "use GPS", other "use compass", but assume we don't have such cheating devices (not to mention their data might be wrong and misleading).. How would you calculate velocity (so also kinetic energy) of such airplane.. ?
-
I don't think so that's true. Charged particle is existing regardless of opposite charged particles. Intergalactic space is filled with relativistic accelerated protons emitted by stars in the all directions, that are f.e. one per thousand km3 And their kinetic energy and charge remain unchanged even though the closest galaxy can be hundred thousands light years far away.. If I will take Stirring rod, start rubbing, and charging f.e. electrostatic plume, electrons-charges will gather on its branches and they will be repelling.. I can take positively charged source (that lost electrons to charge plume) to airplane, and fly to 2nd side of Earth. It won't make difference. Plume still will be charged, and its branches pointing up..

Transfer of information with speed greater than speed of light is not a problem?? Without doubt. Positron and electron that are at greater distance are not annihilating.. Otherwise we would not be able to hold positrons in magnetic trap. About what distances you're talking about? Travel of distance equal to f.e. Compton wavelength would take 8.07*10-21 s at speed of light. Positronium has decay mean-life time that it's >10-10 and >10-7. Electron-positron pair with parallel spins have different half/mean-life than electron-positron with anti-parallel spins. Did you actually read article I gave?

Dune is actually series of 6 books made by Frank Herbert (and even more by his son). http://en.wikipedia.org/wiki/Dune_%28franchise%29 Reading 1st volume is just beginning. It's hard IMHO (1st the easiest).

Why hasn't anyone invented a program that can write a program?
Sensei replied to 123person's topic in Computer Science
Again, and again, it has nothing to do with subject of this thread.. Learning by NPC is not implemented by self-modifying code and then execution of that code, but storing data in database. Ready code is just reading and writing database. No limit in levels - because they're randomly generated. -
While asking my question, I was concerned about this part of post "This is done in a period of time which is much smaller than the propagation time for light between the positions of electron E and positron P. I realize that 'simultaneity' is not possible, but it shouldn't matter."

Powering number to 2 is equal to multiplication of number by itself. Multiplication of negative real number by negative real number, will give positive real number. [math](-2)*(-2)=+4[/math]

I am going from home to shop, straight line with length. Then from shop to home, it's the same equal length. One can calculate length using above equation looking from home to shop, or from shop to home, and it'll be the same scalar length. That is not accurate. Mathematically, a square root has two results, one positive, one negative. Rethink once again bold by you sentence. You have positive number and taking square from positive. What will be result?
-
[math]Length =\sqrt{x^2+y^2}[/math] for 2 dimensions [math]Length =\sqrt{x^2+y^2+z^2}[/math] for 3 dimensions [math]Length =\sqrt{x^2+y^2+z^2+...+zz^2}[/math] for n-dimensions Where x,y,z....zz are relative. i.e. x=x0-x1,y=y0-y1 etc. Powering negative number causes it to be always positive, then getting square from only positive will return only positive results. Line must be closed line segment (have two ending it points) http://en.wikipedia.org/wiki/Line_segment if line is half-open line segment, or open line, it's length is infinite and above equation for length of line cannot be used. http://en.wikipedia.org/wiki/Euclidean_distance

This is what happens to electron and positron prior their annihilation.

On the road to prove Fermat's Impossiblity Equation !
Sensei replied to Commander's topic in Mathematics
Just a small note: We can have binary number that's not integer, but finite fractional. f.e. if we write: 0.1011 it will be: 2-1+2-3+2-4=0.5+0.125+0.0625=0.6875 Binary %1011 is 11 in base 10. 11/16=0.6875 -
How to delete personal account and create a new one?
Sensei replied to Vexen's topic in Suggestions, Comments and Support
That would be cheating. Like getting new life, new incarnation, after committing crime. People would not know about what you have done in the past. -
I realized this could be checked experimentally. On bottom we have laser emitting red, green and blue photons "at the same time". Then they have to pass through medium with exactly the same distance, but slightly different refractive index for each photon. Then after exiting medium they should be out of original sync, first delayed more than second, than third, if velocity of photons in medium were different.
-
Wave nature of particles we examine using f.e. single slit (diffraction), double slit (Young's double slit experiment) You should buy red, green, blue lasers, single slit and double slit, prism, polarization filters, diffraction grating. They're pretty cheap. Different color laser, will give slightly different result with them. Make separate threads about each of these effects in mainstream physics, and I will make photo showing you how they look like.
-
I am not flaming you. That's me who instructed you what experiments you should perform next in your original thread. There is no "reflective index", but "refractive index". http://en.wikipedia.org/wiki/Refractive_index I didn't see any test with refractive material performed by you. Your original video had no such experiment. I only saw two mirrors quasi-parallel to each other.

Which things do you think are "permanent elements"? What is mass-energy of "phantom matter"?

You know nothing about science, and you're writing such text... Disgusting.. Scienceforums.net servers are in UK. People writing here are in USA. Distance between USA and UK is 5571 km. Below ocean there is fiber-wire sending data. If it would be ending up after 49 bounces, like you claim, one straight line segment would have to have 5571 km/49 = ~114 km. Even bending fiber wire in circle and pointing laser to one end wouldn't work... Buy fiber wire and check this carefully experimentally..

http://en.wikipedia.org/wiki/Tax_evasion_in_the_United_States "The Internal Revenue Service (IRS) has identified small business and sole proprietorship employees as the largest contributors to the tax gap between what Americans owe in federal taxes and what the federal government receives. Rather than W-2 wage earners and corporations, small business and sole proprietorship employees contribute to the tax gap because there are few ways for the government to know about skimming or non-reporting of income without mounting more significant investigations." "A more recent study estimates the 2008 tax gap in the range of $450 to $500 billion, and unreported income to be approximately $2 trillion. Thus, 18 to 19 percent of total reportable income is not properly reported to the IRS" "In 2012, the IRS assessed civil penalties in 37,910,493 cases and 4,994,926 abatements." This clearly show that tax evasion mentioned by government is only detected one (imagine really undetected) and it's not detection of the richest but rather ordinary Joe Smith, 1 per 5 ordinary taxpayers. W-2 wage earners and corporations can use such sophisticated methods that they will largely remain undetected. "The typical tax evader in the United States is a male under the age of 50 in the highest tax bracket and with a complicated return" "2013: Big Four accounting firm Ernst & Young agreed to pay federal prosecutors $123 million to settle criminal tax avoidance charges stemming from $2 billion in unpaid taxes from about 200 wealthy individuals advised by four Ernst & Young senior partners between 1999 and 2004."
