Special Relativity is used in high energy physics, quantum physics, nuclear physics (decay of unstable isotope) etc. etc.

Crush ("have a crush on (someone)") "3. an amazing thing that gives you feelings of nerves and excitement whenever you see them" http://www.urbandictionary.com/define.php?term=Crush&page=2 I would say, in many cases, it's correlated to lack of personal self-confidence.

Check my signature, and learn from it how to calculate decay energy of some unstable isotope or particle. Particle that has more mass-energy can spontaneously decay to other particle with smaller mass-energy. But not reverse. To induce reverse process, there is needed supply of additional mass-energy from external source. f.e. to split Deuterium atom you need to supply 2.22 MeV energy (mass-energy of Deuterium nucleus is md=mp+mn-2.22 MeV/c^2 = 938.272 MeV/c^2 + 939.565 MeV/c^2 - 2.22 MeV/c^2 (mass-energy of free proton plus mass-energy of free neutron))

Polished Gold could be used as mirror... "Spanish chronicler Diego Durán described the image of Tezcatlipoca in the Great Temple of Tenochtitlan as being fashioned from polished obsidian and bearing a mirror of polished gold. The deity was supposed to observe everything that happened in the world through his mirror." https://en.wikipedia.org/wiki/Mirrors_in_Mesoamerican_culture

AFAIK, "American dream" means opportunity to go from shoe cleaner to millionaire. In the last ~30 years there was plentiful of examples of very fast going unbelievable rich in newly created IT companies ("unicorn startup"). https://en.wikipedia.org/wiki/Unicorn_(finance)

For what purpose? If you want to have 12 V, connect 8 1.5 V batteries in serial. If you want to have 9 V, connect 6 1.5 V batteries in serial. If you want to have 4.5 V, connect 3 1.5 V batteries in serial. If you want to have 3 V, connect 2 1.5 V batteries in serial.

Synthetic diamonds are small. Smaller number of carats. The world record of synthetic diamond in 2016 was 10.07-carats. http://www.jewellermagazine.com/Article.aspx?id=7039&h=‘World’s-largest’-synthetic-diamond-record-broken-again Queen Victoria had diamond crown in XIX century... https://en.wikipedia.org/wiki/Small_Diamond_Crown_of_Queen_Victoria Diamond jewelry industry for nobles, kings and queens predate 1930 by centuries, if not millenniums. https://en.wikipedia.org/wiki/Crown_Jewels_of_the_United_Kingdom After I world war they vanished in many European countries, so alternative customer was needed. "The first well-documented use of a diamond ring to signify engagement was by the Archduke Maximilian of Austria in imperial court of Vienna in 1477, upon his betrothal to Mary of Burgundy." https://en.wikipedia.org/wiki/Engagement_ring ps. I agree it's silly usage, for jewelry, either of Gold or Diamond. I am using Gold in scientific experiments. It's good at stopping radiation, and inside of scientific apparatus.

They are made of synthetic diamonds https://en.wikipedia.org/wiki/Synthetic_diamond Search for "synthetic" here https://en.wikipedia.org/wiki/Diamond_blade

Analyze two situations: 1) somebody ingest unstable isotope which is decaying by beta decay minus exclusively, daughter isotope is stable, let's say up to 400 keV energy electrons are created. High energy electron fly through body, ionizing atoms, destroying molecules through which it flies. Electron decelerate giving away its kinetic energy to surrounding matter. And it's end. 2) somebody ingest unstable isotope which is decaying by beta decay plus exclusively, daughter isotope is stable, let's say up to 400 keV energy positrons are created. The same half-life as in the 1st case. The same energy released by the event. High energy positron fly through body, ionizing atoms, destroying molecules through which it flies. High energy positron decelerate giving away its kinetic energy to surrounding matter, and finally it's annihilating with some random atom electron in random molecule in body (molecule is destroyed, goes random chemical reaction with surrounding it molecules). And now finally you have 2 or more gamma photons that passes through body, and perhaps scattering, ionizing random atoms and molecules, if/when they interacted..

The price for some goods reflects human willingness to buy them. Price raises when there is more buyers than sellers, and vice versa.

Anti-electrons (aka "positrons") are later annihilating with electrons, producing high energy gamma photons. Thus this decay mode can be much more dangerous than just plain beta decay minus. Tritium (the only decay mode is beta decay minus) is so small radioactive that it's used in watch clocks. Each unstable isotope, each unstable particle, has to be analyzed independently from other. Their half-lives are different. They release different energy. You must analyze of what is their daughter isotopes and the all their decay paths.

True versatile AI is never "explicitly coded" to do something or not do something. AI has to learn from environment in which it "grows up".. If you would put fresh new AI in nazist's camp, you would get AI believing in hitler, supremacy of white race, humans and sub-humans etc. etc. The same fresh new AI put to liberal family would learn exactly reverse..

Radioactivity is no doubt harmful. Even scientists working on Manhattan project had chance to feel it by themselves... they died in accidents: https://en.wikipedia.org/wiki/Harry_Daghlian https://en.wikipedia.org/wiki/Louis_Slotin

You would have to start with definition of morality or immorality. I would have to google what does it even means.. For everybody it means something else. For some people walking topless is immoral (according to their own personal definition). For some other people walking without Niqāb or Burqa is immoral.. (repeat question 7.5 bln times and you will have the all data, and it changes from century to century) If there would be created versatile AI and it would hear that somebody consider walking topless, or without face cover, is immoral, would probably get to conclusion that humans are nuts.. You would have to explain your AI, why walking naked in your own apartment/house/garden is "moral", and the same outside of some places, is "immoral" (and it's not constant, as some other people have no problem showing topless on the street in f.e. Africa or South America).

They are created all the time, but they have short half-lives, and remain in the core of star, until supernova explosion. Majority of radioactive isotopes here on the Earth have origin in Uranium-235 with 704 millions years half-life, and Uranium-238 with 4.468 bln years half-life. Both are very little radioactive (long half-lives). But daughter isotopes created by them are short-living isotopes. And daughter of daughter are also unstable etc. etc. They are decaying until they reach Pb, or other stable isotope. They were created in supernova explosion billions years ago. During supernova free neutrons are created and are captured by heavy nucleus like Iron, Nickel, or other present in the core. Neutrons can be rapidly captured, in r-process. https://en.wikipedia.org/wiki/R-process Neutrons can be slowly captured, in s-process. https://en.wikipedia.org/wiki/S-process Protons can be captured, in p-process https://en.wikipedia.org/wiki/P-process Protons can be rapidly captured, in rp-process https://en.wikipedia.org/wiki/Rp-process

Positron emission (beta decay plus) does not happen often on the Earth, but it happens all the time in the core of the Sun. Currently approximately 1.8344*10^38 times per second.

There are 6 beta decay nuclear transformations: Beta decay plus (aka "positron emission"), proton changes to neutron and releases positron to conserve charge, and neutrino to conserve Lepton number. https://en.wikipedia.org/wiki/Positron_emission Beta decay minus, neutron changes to proton and releases electron to conserve charge, and anti-neutrino to conserve Lepton number. https://en.wikipedia.org/wiki/Beta_decay Double beta decay plus, releases two positrons and two neutrinos. Double beta decay minus, releases two electrons and two anti-neutrinos. https://en.wikipedia.org/wiki/Double_beta_decay Double beta decay plus neutrinoless, releases two positrons and no neutrinos. Double beta decay minus neutrinoless, releases two electrons and no anti-neutrinos. https://en.wikipedia.org/wiki/Double_beta_decay#Neutrinoless_double_beta_decay Example of weak interaction which does not originate from proton/neutron is decay of muon [math]\mu^- \rightarrow e^- + \bar{v}_e + v_{\mu}[/math] [math]\mu^+ \rightarrow e^+ + v_e + \bar{v}_{\mu}[/math] https://en.wikipedia.org/wiki/Muon During the first stage of fusion, diproton, Helium-2, sometime decays by positron emission and changes to Deuterium: [math]_2^2 He \rightarrow _1^2 D + e^+ + v_e[/math] https://en.wikipedia.org/wiki/Isotopes_of_helium#Helium-2_.28diproton.29

Somebody can become racist, enemy of some nation, intolerant for homosexual people, etc. etc., because of traumatic personal experience, f.e. being harmed by other race person, being harmed by other nation person, or f.e. because of being raped in the past.. And almost none good/bad parenting or education can help with this. Because of bombarding and occupying eastern countries you're just making more and more enemies, from people who previously were neutral, after they lost family members, friends, homes, jobs, life.. It's called by milliary officers as "collateral damage". I could call it "how to make new enemies". It's extremely hard to forgive.

In #3 post, he said, he wants to make metallic Sodium and Potassium..

It was LightWave 3D. It's destructive workflow, which means there is no easy way to modify it after it's done. Unlike non-destructive workflow, i.e. modifier stack and history stack, in which you can modify parameters of applied modifiers after the fact (and the rest of 3D object is automatically regenerated, as it's procedural object). Download some 3D app, or use Blender or SketchUp. Take my 3D object as starting point, and boolean subtract one cylinder from my cylinder to make walls thinner. Blender boolean subtraction of one 3d object from other 3d object:

In the case of I/O, currently are used techniques such as DMA (Direct memory access): https://en.wikipedia.org/wiki/Direct_memory_access f.e. hardware driver is setting address, length of buffer and other properties, operation is started and it's working parallel to CPU (transfer does not block CPU, like in old techniques) At the end of data transfer CPU is informed about it, by special interrupt request IRQ. https://en.wikipedia.org/wiki/Interrupt_request_(PC_architecture)
