Ramifications of electrons not having gravitational mass (split)
Sensei replied to John Cuthber's topic in Speculations
I didn't read whole thread, so sorry if it's been already said, but if f.e. electrons would not be accounted in gravity then all calcs are going to be invalid, including mass of Earth.. Take for example mass of Iron-56 https://en.wikipedia.org/wiki/Isotopes_of_iron It has mass 55.9349375 u = 9.28821407766474E-026 kg In electric neutral state, it has 26 electrons, each with mass-energy around 510998.928 eV/c^2 (ignoring energy needed to release free electron) 26 * 510998.928 * 1.602176565e-19 / 299792458^2 = 2.36843955843932E-029 kg 2.36843955843932E-029 kg / 9.28821407766474E-026 kg = 0.0002549941 0.0255% of mass of Iron are it's electrons. In Hydrogen it's 0.05446% For single atom, it's not huge difference, but for mass of Earth it's really huge difference. As it would be 1.5e+21 kg difference.. Average m^3 of Earth is 5505 kg or so, 0.0255% from it, is 1.4 kg. -
If you're issuing patent to office you should have ready device showing how it works in practice. So? Do you have device? Did you tested it? Show on YouTube video for instance.. IMHO you don't even did research with electroscope.. You would see that "stationary charges" are stationary in very specific moments.

You should always mention which relativity: whether it's special relativity or general relativity. In the article they said about special relativity. You truncated it to just "relativity". Special relativity is all the time used while calculating f.e. high energy particles collisions, and decay of unstable isotopes inside of Cloud Chamber, Bubble Chambers, or other particle detectors. So newly produced particles, daughter isotope, and f.e. electron, positron, proton, neutron, alpha, etc. there is used special relativity to calculate their energies and momentum. So amount of direct evidence in front of eyes is tremendous. One could argue 'what is mass', 'what is energy' etc. But equations from decays agree to 1 per billion precision or so. Special relativity also conserve mass-energy to every "piece", (f.e. photon energy prior pair-production = electron mass-energy + kinetic energy of electron + positron mass-energy + kinetic energy of positron), regardless of FoR, while GR and BB do not. Universal time does not disagree with special relativity, when calcs are done with mass-energy. There is no sensible way to determine 'universal time', as there is no reliable reference points (f.e. always immobile) in the Universe.

That should be banned! It's mistreat with cruelty poor chimp..

No. It's what I called 'tick', in my simplified example algorithm in post #3. Periodical update of all cells to new state. And to simulate various speeds, there are counter and timer variables. For photon-like particles timer would be 1. So they run at full speed, while others run slower.

Red Pepper Plantation, 309 plants at once. I moved them from old container (it was permanently dry) to seedling trays. There is more of them (331 so far), but didn't manage to get on board of seedling trays..

If Planck Length (L) (or any other length unit) is going to be "elementary" length. That's how far is one cell from the other. And Planck Time (T) (or any other time unit) is going to be "elementary" time. That's it, no fraction of it allowed, only positive integers. (quantization of length and time) Then macro scale velocities should be quantized in similar way: [math]v=\frac{L*x}{T},x=integer[/math] (in this case velocity is also integer quantized) or [math]v=\frac{L}{T*x},x=integer[/math] (in this case velocity is not integer quantized) With L and T, normalized to 1, x is the only variable. It's very easy to write algorithm for something like this, but describing it mathematically? Imagine you've array (2d) of cells, class Cell { private: bool particle; // true if cell is filled, false if empty // some other properties, like charge, mass? int x,y; // location in array int vx,vy; // where particle should go in the next time (x,y,vx,vy could be floats) int counter,timer; }; Cell cells[ 100 ][ 100 ]; Now for each time, for each non-empty cell in array, counter is decreased by 1. And if it reaches 0, particle swaps content with the one at cells[x+vx][y+vy], and counter=timer again. There is also needed collision detection. If that cell is non-empty, there is hit, and new vx,vy are needed to recalculate, and/or annihilation, and/or absorption etc. etc. If timer=1, cells are swapped/collision-tested the most often (the largest "velocity"). How about algorithm generating waves? It has the same begin as above. We have array of cells. But they have the only parameter: amplitude. For every time tick, for every row, every column (for 2d array) amplitude of cell is decreased by f.e. 8 (or some other variable), then surrounding it cells get +1 (because in 2d, 3x3-1=8) (in the case of using different variable than 8, then decreased by variable/8 "conservation of energy-momentum"). There is needed to write to spare array (so same cell is not subtracted/incremented multiple time, different row/column process), and swap them every tick. When you will start with central cell with f.e. 100, you will see waves spreading similar like in the real world. And you have wave effect, without any movement.. Sum of all cells will remain 100 regardless for how many cells it'll be spreaded.

Maybe this will help a bit: http://honeybeesuite.com/do-brussels-sprouts-need-pollination/ See also Rusty msg in comments. OTOH, they have edible buds. From my language wiki: "Brussels sprouts can not proceed after the other cruciferous vegetables, cucumbers and pumpkins." There are plants that can self pollinate, other needs bees, and exchange with other plants on plantation, yet another different kind of insects. If you have just "male" plants, or all "female" plants, they won't be able to reproduce. Unless they have either one on single plant, or switch sex. It's better described here: https://en.wikipedia.org/wiki/Plant_reproductive_morphology "Like Amborella, some plants undergo sex-switching. For example, Arisaema triphyllum (Jack-in-the-pulpit) expresses sexual differences at different stages of growth: smaller plants produce all or mostly male flowers; as plants grow larger over the years the male flowers are replaced by more female flowers on the same plant. Arisaema triphyllum thus covers a multitude of sexual conditions in its lifetime: nonsexual juvenile plants, young plants that are all male, larger plants with a mix of both male and female flowers, and large plants that have mostly female flowers.[15] Other plant populations have plants that produce more male flowers early in the year and as plants bloom later in the growing season they produce more female flowers.[citation needed]" Green house could make harder bees and insects to get in, if plant requires them.

No, you're not right. Pair production is well known since at least 1948. https://en.wikipedia.org/wiki/Pair_production Energy from decay, is simply kinetic energy of outgoing newly produced particles. If you have Beryllium-8, it decays quickly to two alphas for instance. [latex]_4^8Be \rightarrow _2^4He + _2^4He + 91.84 keV[/latex] Decay energy is split in half to each newly created alpha (Helium nucleus), as they have equal mass, so they will carry the same momentum, and same kinetic energy. Just in opposite directions.

Magnetism - where does it's energy come from?
Sensei replied to Old Guy In Stanton's topic in Classical Physics
In this video, showing the basic electromagnetic induction, source of energy, initial acceleration comes from gravity: See how slowly magnet is passing through Copper pipe, in the second part of video. It's three-four times as long as not magnetized piece of Bronze. -
Cosmic space is way more destructive environment, than Earth's conditions. Space crafts look like Switzerland's cheese under electron microscope due to constant bombardment of it, and passing through entire body of rocket, relativistic accelerated cosmic rays.. If you're on orbit, and close eyes, you will see white dots. Rays pass through spaceship, and hit eye. Similar like CRT TV is generating image, by electrons hitting screen, after being ejected by electron gun, but with much higher energies. https://en.wikipedia.org/wiki/Cosmic_ray_visual_phenomena

The first lemon tree that appeared from soil (in common container with Aronia), and was immediately moved to separate container with soil (to make room for others): Second lemon tree, moved today: See it's size! It's nearly double size of the first tree, even though it was 2nd in row. Third, the last one that appeared from soil, now is the biggest from the all of three, so far?! While moving it from soil, it appeared, that it's root is much bigger than overall plant on the surface. So, had to put it to coca-cola container instead what I planned originally, because would have to bend its root in literally circle.. Comparison between them on one image, so you can estimate their sizes: I was making "holes" in new lemon seeds (with needle, so they can drink water more easily), 20+ new one to put to the soil, and started mixing them with soil, and found out that old seeds released roots, some even to 5 cm, so far, perhaps weeks ago, stopped counting them at 7+, so I had to prepare space for them in Aronia container.. That's why all this movement of old plants to new containers.. Including these seeds which released roots, and plants on surface, I have totally 14 lemon trees so far. I will need to buy new 10L soil tomorrow, so their roots will be able to grow correctly.. ps. The all of them grew on artificial light source, 100 W light bulb.

Actually it looks kinda like sodium-potassium discharge tube by color.. One could use prism to split light by their wavelengths, and analyze their spectral lines.. According to https://en.wikipedia.org/wiki/Grape have plentiful of: Potassium 191 mg Magnesium 7 mg Calcium 10 mg Sodium 2 mg (in 100 g of product). What I would try is take some potassium/sodium/calcium/magnesium salts, to two (small) containers with water, solutions, and connect them by little strip of paper to make bridge between them. And put to microwave oven, and see what happens.

What is it? Show source code to generate it..

Say we have atoms that are not in ground state. If we send photon beam with right properties, which is enough to bump atom's electron to even higher energy level, than now, once electron go back to ground state, it can emit photon with even larger energy, than it absorbed from initial photon. Like in Hydrogen case, to visualize it. Suppose so it has n=2, transition from n=2 to n=3 require absorbing 13.6 eV / 4 - 13.6 eV / 9 = 1.8889 eV but then Hydrogen can go straight from n=3 to n=1 by emitting photon with 13.6 eV - 13.6 eV/9 = 12.08889 eV

Link you posted has no mention of Fluorine/Fluoride... Radioactive product of fission is Rubidium,Caesium,Strontium,Barium,Lanthanum. These are dissolve-able in water. Rb/Cs, pretty good, other weaker.

If I misunderstood OP intentions (I just drunk 2L of my wine 16%= 320 mL of ethanol), and he does not bother about security too much, he could try: - setting up custom FTP server, - setting up custom HTTP server, Apache for instance, better with HTTPS, - setting up Direct Connect server, - setting up SVN. It's especially designed to work with multi people team, to exchange data, and all have up to date files. With authorization per-person. With history what person changed in files. You can go back to older version of each file, from history. It's for programmers, but don't see a reason why not to use it by scientists. All these require that you have static *) public IP address, or if you're behind NAT, that router-modem has at least one port forwarded (in the case of FTP, might be needed more) *) there are special dynamic IP host renaming services as noip.com, I have been using it for many years when I had dynamic IP. It was updated every day, every local IP change. ps. SVN is especially tempting. Ask programmers in your team how it works locally. It can be used without Internet connection in intranet.

Sounds like you bother about security. Then the only way is heavily encrypted (plus better compressed with self-made compression algorithm) direct transmission between two parties. Somebody would have to capture entire transmission (so, would be advised to split it, to thousands alone meaningless packets), then bother to decrypt, and find out personal decompression algorithm, to read data. It would be better to have packet tracer implemented in sending algorithm, to check which IP are listening all your transmission. Or going personally with CD/DVD/pendrive every time you need to exchange valuable data (also encrypted, compressed with self-made compression algorithm). You can't send them by mail/courier and being absolutely sure that somebody unauthorized not read them. Not bad security level is given by Skype data transmission protocol, as long as, one of you at least, sender and client, have public static IP address. But still better try to send test (meaningless) data, each time, and see in personal firewall (with packet logger enabled) which IP were used by packet/transmission. To be sure it's direct transmission p2p. IP must match your client. If sender and client are private/dynamic IP, behind NAT etc, data transmission is not p2p, but through somebody else computer (who is either receiver from you and sender to your client), and they could intercept transmission. Yet another ridiculous your post. Why don't you simply send everything to CIA/NSA/everybody straight away... That's what you're suggesting..

Observation = measurement. Photon emitted by system, is absorbed by your eye, or by digital, or analog camera, and is gone from system under observation. You, or device, "eat" photons and change state. In the case of double-slit, it could be polarization filter. It's working this way that if we have unpolarized photons beam, and they are emitted toward polarization filter, 50% of them will pass through, 50% of them will be reflected. But if beam is already polarized, and right polarization filter angle is used, 100% of photons will pass through polarization filter, and 0% being reflected. Or after rotating polarization filter +-90 degrees, 0% of photons will pass through polarization filter, and 100% being reflected. So by putting polarization filter, you made measurement of particles-photons. You learned their polarization. But beams that are passed through, or reflected, are no longer unpolarized, nor they are linearly polarized. So you can put yet another polarization filter behind them, and see what happens. It's quite interesting. Do it below water with blue laser, to see beams. Act of observation (measurement) changed state in which are particles under observation.

Like I showed earlier, it's not needed at all to search for angle. sin(angle)=a/c sin(angle)*c=a But actually, you are interested to know a, not angle, not sinus of angle. and you can simply do Pythagoras formula to find a (b is from for-loop counter, c is radius of circle). 2*abs(a) = area of single row in pixels. Sum rows area together in loop, unit it exceeds threshold area of region, and you know when to draw separation line.
-
If you have center at cx,cy which typically is radius=diameter/2 cx=radius cy=radius point on circle will be given by x=cx+sin(angle*2*PI/360)*radius y=cy+cos(angle*2*PI/360)*radius with angle in degrees between 0...360 Please notice that you have right triangle (with lines a,b and the longest c) with coords: cx,cy cx+sin(angle)*radius,cy+cos(angle)*radius cx,cy+cos(angle)*radius a/c=sin(angle) b/c=cos(angle) c^2=a^2+b^2 Area of circle is PI*radius^2 So, area A in your image has PI*radius^2 * percentage of A/ 100 pixels area B, has PI*radius^2 * percentage of B/100 pixels You can make for-loop going from i=0 to diameter, convert it to b=i-cy, and convert it to angle (cos(angle)=b/c) calculating left circle pixel (cx-sin(angle)*radius), right circle pixel (cx+sin(angle)*radius), (c is known, and b is known, so you can use Pythagoras formula to learn a, instead) difference between them will be quantity of pixels (area of single row). And sum them together. After that variable exceeds area of A (given above formula), then you draw horizontal line. And subtract from variable area of A (or clear variable, but more precise will be subtract). And then you continue loop. That would be probably not bad algorithm, even though it's going row by row, pixel by pixel. It's called scanline algorithm. But you would like to fill areas with different colors, right? Then difference between drawing line inside of circle, is what color is used: if it's separation between one area A and B etc, choose black color, otherwise pick color from array of colors for regions (Index increased after drawing separation line between them)

Quantum physics is "not just math". Math is *result* of observation, by naked eye, which was *first* (recorded event 1894 year, XIX century *). If you want to see electrons traces, alpha traces, traces leaved by any charged particle, on your naked eyes, build Cloud Chamber particle detector, like I am repeating to every layman here.. http://www.scienceforums.net/topic/92998-universal-evolutionary-process/page-4#entry900023 http://www.scienceforums.net/topic/92471-the-limits-of-physics/#entry894800 Once you know how something behaves in medium such as air, leaving trace, you can fill it with f.e. liquid Hydrogen, and also record traces, of high energy particles, passing through it. You can suck gas out, and have vacuum, but method of detection of particles must be different. As they cannot leave visible trace (that could be photographed or filmed) in vacuum. We had dozen years ago detector, which had 500 or so x-ray cameras, each one was making photo using x-rays, with slightly different delay, with slightly different angle. X-rays were passing through chamber without interaction with particle, if didn't hit any. So each charged particle was leaving information where it used to be because of shadow on x-ray photography. If you have hermetic metal sphere, with internal surface covered by photo detectors, with vacuum inside, and you will emit there electron and positron pair, they will annihilate. Photo detectors typically will detect just two hits, made by gamma photons from annihilation, on the opposite sides of sphere, if annihilating electron-positron had no kinetic energy (same frame-of-reference as sphere is in). *) read history of Cloud Chamber.
