    Will we get brain-computer interfaces by 2037?

    If computer will be connected directly to the brain, and sending detailful data indistinguishable from the real world, you won't be able to tell if you're playing or living at given moment. ps. Maybe you are already? How can you tell? During playing human learns and have pleasure. Learning should not be boring and painful. People should not hate learning. Playing game which teaches you something is very convenient and effective way of gathering knowledge.
  2. If you want to base compression algorithm on primes you must 1) precalculate them 2) calculate at run time. What else options do you have?! Programmers precalculate data to have quick access to them, as calculation at run time would take significant much more time.. ...but it must be done in less than minutes or seconds... if it would be taking hours, days, months, or years.. useless for anybody.. Sounds you have no experience in programming.. Maybe you should start from making brute-force algorithm finding primes, for as start? To see how many primes it's able to find in let's say 60 seconds of execution?
  3. ..which cryptography algorithms rely on the least common multiple.. ?
  4. Even if you will manage to make such compression algorithm, decompression will be fast, but compression will be very slow. Do you want to make pre-calculated array of primes in memory? How many primes do you want to store? Classical approach of compression is to find pattern in data, and store indexes or so, to book of sub-strings. f.e. 0xFF00FF00 = %1111000011110000 we see there is repeated 0xFF and 0x00, and 0xF and 0x0, and 0xFF00, data stream %00 and book with 0xFF00, or data stream %0101 and book with 0xFF and 0x00, or data stream %00110011 and book with 0xF and 0x0. Additionally there can be variable number of bits for index in book. The more often repeated pattern, the shorter sequence of bits to store it in the stream. Such methods work especially good for txt file. The most used words as represented by the smallest number of bits in the stream.
  5. Newspeak https://en.wikipedia.org/wiki/Newspeak George Orwell.. Replacement of one sentence which has bad connotations, with another sentence which sounds much harmless.. "Terrorists were eliminated", "suspect has been neutralized", and so on, so on...
  6. Average American is unable to show North Korea on the globe or the world map..
  7. They believe in their own race superiority, culture superiority and sexuality superiority over the rest.. They have been brainwashed at early stage of their life. By intolerant indolent stupid parents, irresponsible teachers, populist politicians, evil priests. It would cause reverse effect. They would hate more instead of less. How long would you like to imprison them anyway? Till they stop thinking the way they think? That's not their fault that they grew up in intolerant community, and their brains were brainwashed, by e.g. anti-LGBT propaganda.. or anti-immigrant propaganda.. etc. etc. It's hard (sometimes impossible) to fix somebody after brainwashing. Certainly it is long time going process. North Korea and other totalitarian countries have re-education camps.. Do you want to implement them in western countries?! In prison people find other criminals, make friendship with them, and instead of having less criminals, after they are out of prison, community has more criminals.. Learning tolerance to other people should starts at school, primary school. Especially if class is not uniform. Kids learn that black, white, yellow, gay and lesbian are also good humans and good friends.. ...increase of tension between minorities, between members of different races, between native and immigrants, between hetero and homosexual people is toy, is tool, of evil populistic politicians who want to divide-and-conquer minds and perhaps lands of community in which they operate. Weak minds are easily fooled.

    to make green

    Learn about hydroponics https://en.wikipedia.org/wiki/Hydroponics It is a method of minimizing water usage, which should be especially important in such hot areas as India. i.e. at the bottom concrete hermetic basin, with many levels of Aluminum shelves. Everything covered by transparent foil. Everything designed to disallow escape of water from inside of greenhouse. Water gathering at the bottom of floor, should be filtered and reused. Solar panels use to make electricity which will be used to power water pumps, filter water, making artificial rain at the top of greenhouse. Pipes with water should be going directly to each plant and have electronically controlled release of water and release of artificial rain. If you're not yet using greenhouse start from reading Wikipedia page about them: https://en.wikipedia.org/wiki/Greenhouse

    Epistemological Question

    It's easy to imagine how enzymes were introduced by random mutation to living organisms. If we have organisms without enzymes, it has worser yield of production of some compound, or processing nutrients etc. Random mutation (caused by radioactive decay of C-14 or K-40 etc., or cosmic rays, or radicals etc.) at some point of time, changed RNA/DNA in such a way, that new compound has been produced, compound which was/is accelerating some process, enzyme/catalyst of some sort. It was (and is) useful in getting better yield, so organism with such mutation was more successful in surviving, and spread that mutation to further generations, spread itself around the world. Organisms without mutation died or were forced to move to some niches in environment. If we would make computer program which is going through the all possible states of memory with fixed size f.e. for 256 byte size memory, it's 256 ^256 states = 3.23e+616, one by one, and trying to execute it as program, at some moment, such loop would find some useful meaningful combinations of commands in the right order, doing something for real. It's just a matter of time by otherwise unaware, non-thinking algorithm, to find something useful, and interesting. The all books on the Earth has fixed/limited number of pages, with fixed/limited number of characters used to make them. One could go through the all characters one by one, pages one by one, to fill them with randomly chosen characters. After some time (counted in probably billions+ of billions+ of years) it would get the all books ever written and not-yet-written by humans. (examples of brute-force algorithm, which is very time consuming task for finding something useful from garbage of information) Catalyst is just helping getting better yield. Reaction can be going without it, but at slower rate.

    Epistemological Question

    Human, animal or plant is performing previously learned task (or encoded in DNA f.e. reflex action) in specific moment. i.e. escape (action) if there is danger (stimulus). Non-reflex action can be controlled (also by learning and training). i.e. training how to not feel fear at high altitude, training how to not feel natural fear against wild predator animal etc. Chemical compound is going into reaction with other compound, if their molecules hit each other, and other environmental variables meet sufficient criteria. i.e. it happens spontaneously.

    Discussable Topics

    Personally I think the all threads you mentioned are closed too soon.. Members out of timezone of participants of the threads were completely unaware of the threads you mentioned, and could not participate in them in any senseful ways.. Closure of "Neil deGrasse Tyson (...) " thread is premature and senseless..

    UFO evidence and aliens.

    @Phi for All @koti I just described how terrestrial material is compared and detected with hypothetical extraterrestrial material. If extraterrestrial material has the same isotopic composition as Earth's, then you detect nothing! If terrestrial material has abnormal isotopic composition than "Earth's average", you are fooled!

    UFO evidence and aliens.

    Phi, you should be knowledgeable enough to know there is just one stable isotope of Aluminum with 13 protons and 14 protons. To confirm extraterrestrial object there is used isotopes comparison method. If there is different isotopic composition, it's at least "suspicious".. which is by some scientists extrapolated to extraterrestrial origin.. f.e. there are three isotopes of Oxygen O-16, O-17, O-18 (O-19 is decaying to F-19). We take Earth sample of stuff, and check Oxygen isotopes. And find it is matching "Earth's average". Take another sample, and find it has extraordinary abundance of O-17 or O-18... Why? Some scientists are interpreting it, that it must be extraterrestrial object, with suspicious isotopic composition, because it does not match Earth's average..

    UFO evidence and aliens.

    ....but remote controlled or automatically controlled flying object can exceed speeds and accelerations possible for aircraft with human being on board.. It does not have to be extraterrestrial at all. ...are you sharing knowledge with chimps.. ? I am still waiting for decoding animal languages by humans...

    ..you are waiting for extraterrestrial knowledge given on "golden plate" for you to acquire.. ..like US military officers..

    UFO evidence and aliens.

    Extraterrestrial intelligent life forms on the Earth, are like humans in the jungle exploring it. Biologists who want to learn about species in their natural environment. Biologists do everything to cover against being noticed by animals under observation, as it scares them, and changes natural behavior. Humans also tries to keep the last South America tribes unaware about the world.. https://en.wikipedia.org/wiki/Uncontacted_peoples
  21. ..anything remote controlled can outperform airplanes which have human on board.. Human is limiting aircraft because of acceleration. Too rapid acceleration and pilot loses consciousness.

    Solving the US China Trade defecit

    thethinkertank, it is admirable you want to help solving modern world geopolitical and environmental problems. However your ways to solve them, are completely senseless. You didn't pay enough attention to research subjects you want to address. Which should be essential action. How can US decrease deficit with China? Find something which Chinese people need, produce it, and export it. Hard? I know.. Chinese wages are growing, costs of production of product they sell to the world is growing. The closer they are to western wages, the harder they will be able to sell them. So, deficit problem will solve by itself. There is limit at which cost of components+cost of labor+cost of transportation to entire world will be so close to western prices, product will stop being attractive (at least from price tag point of view) to western customers.

    RFID verichip implanting in humans?

    ..because technology used, and its current name, is in reality irrelevant. It's discussion of electronic identification of a person.. Nightclub offers free WiFi for everybody and does have weak phone signal? They require guests to register and log-in to hotspot free WiFi with their e-mails, Facebook, etc. accounts? They have the all guests data already... don't need RFID chips..

    RFID verichip implanting in humans?

    If one can read chip, can make duplicate which will give the same data in the same moments, and pretend legit user. It's technique already used by car thieves. People who have car with automatic blockage of device are disabling/enabling it from distance. So thief is placing near house reader of signal to get data. Then just replies stored signal and voila. Has access to device.
