  1. 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..
  2. Radioactivity is no doubt harmful. Even scientists working on Manhattan project had chance to feel it by themselves... they died in accidents:
  3. 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).
  4. 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. Neutrons can be slowly captured, in s-process. Protons can be captured, in p-process Protons can be rapidly captured, in rp-process
  5. 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.
  6. 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. Beta decay minus, neutron changes to proton and releases electron to conserve charge, and anti-neutrino to conserve Lepton number. Double beta decay plus, releases two positrons and two neutrinos. Double beta decay minus, releases two electrons and two anti-neutrinos. Double beta decay plus neutrinoless, releases two positrons and no neutrinos. Double beta decay minus neutrinoless, releases two electrons and no anti-neutrinos. 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] 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]
  7. 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.
  8. "Some theories consider sleep to be an important factor in establishing well-organized long-term memories. (See also sleep and learning.) Sleep plays a key function in the consolidation of new memories.[11]"
  9. In #3 post, he said, he wants to make metallic Sodium and Potassium..
  10. 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:
  11. In the case of I/O, currently are used techniques such as DMA (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.
  12. Something like this? Aquarium 3.lwo
  13. Screen-shot from 3D application: 3D objects: Aquarium.obj Aquarium.lwo
  14. Ask average American "where is North Korea?"... and you will get this: WTF?!
  15. They don't even have street lights at night... People who have computer which can handle flashdrive are "elite of N.K.", regime members, family and supporters... (better than nothing, but very far from "ordinary N.K. person") Photo from ISS:
