    Has anyone made a pseudorandom number generator based on how much adding a picture will screw up the formatting of a word document? There must be a way to quantify that and feed it into a program.

      We had an electronic double dice device, but I didn't like the way my Dad licked his fingers before touching it. The noise of the real dice wasn't that bad but Dad preferred the 'random number generator' as he didn't like the board getting scratched by fingernails when picking the dice up! I don't know how random it was and if its probability of each number wsa 1/6 like with dice!

    I'm reminded of a statistics class I took during first year university. We all had to buy a specific type of graphing calculator and were told to go through a particular exercise with a "random" number generated by the calculator. As this was the first time many of us used that function of the calculator, about half of us generated the exact same random number. I think our calculator diverged after that, but it was kind of amusing and a pretty clear illustration of how non-random computer-generated random numbers are.

    • @thefremddingeguy6058
      @thefremddingeguy6058 7 років тому +28

      It might've been because the graphing calculators needed a seed to be inputted from the user, and outputted the exact same numbers with the default seed.
      Or maybe not; that's just what might've happened.

      @duffman18 2 роки тому

      I mean if anything, truly random numbers could end up in results like that anyway. Humans like to think of randomness as the things being different every time. But truly random numbers have a lot of repeats, and a lot of numbers that are never chosen at all. The calculator obviously isn't random because no computer can generate truly random numbers. But yeah the fact loads of people got the same number is, if anything, more random, not less.

    • @Phlebas
      @Phlebas 2 роки тому

      @@duffman18 If what you're saying is that it's a coincidence, I doubt it, mainly because there's a pretty reasonable explanation for all of these calculators coming up with the same random number.
      I get that random results can sometimes create sequences that aren't intuitive. I don't think that's the case here. These calculators were all the same model and fresh out of the package; it makes a certain amount of sense that they would generate identical results with identical user input.

    I chose 1, because of its low chance of being guessed right. I thought 5, 6, 7, are the top contenders on picking a number from 1 to 10.
    The most fundamental part about *random* is all about semantics. Casually it most often means "something unexpected" or "a set of values with equal chances for one to be picked", and in many definitions "something without a definite plan". It is a very contextual word.
    I just love it how one word, random, can so well join psychology, mathematics, culture and linguistics.

      What bitrate can you achieve that way? How long must you wait after reading the sensor once, for the next reading to have 0 correlation with it?
      Doing this a few times might be a tolerable way to generate the value of the *seed* of a PRNG, but for all practical purposes continue by using a computationally slick PRNG.

    Agreed. "Too complex to calculate" is not random.
    It should also be noted that you need outer limits for your random number. In this video they go 1-10, 1-6, 2-12 etc. If it was truly random and open, you could get very very large numbers, and they would be as probable as the lower ones. You also have to limit it to number sets. Do you want negative numbers? Imaginary numbers? Integers? etc.

    I think there is no randomness in the universe. Everything has a cause, even those individual electrons flying into detector not doing it randomly, but because of.. some processes that happens on that particular level. So basically there is no such thing as a random number (or anything, really...), even if we use events that take place in space to generate random nubers they wont be random but will represent 'breath of the universe'.

    @Athenas_Realm_System 8 років тому +4

    Another method used by many operating systems for generating random numbers for cryptography is to take seeds from all kinds of sources like hardware interupts down to the nanosecond and then run an encryption algorithm on it using previous number generated so rather than starting with one seed you have constant reseeding and after a couple minutes running the algorithm for the first time generally the random numbers while still being pseudo-random appear statistically random... Yarrow is one of those algorithms that is used by both /dev/random and the /dev/urandom on OS X (both are linked as OS X doesn't block like linux).

      Current understanding of quantum mechanics is that it is described only by tuly random events and that no larger theory with currently unknown variables can explain our data. This was explicitly tested and ruled out in the Bell experiments, although I'm not an expert in the exact statement of the result.

      The proof is that quantum effects are random since they are the consequence of a wavefunction collapse, and the wavefunction is nothing but the probability amplitude of a state.

    A small upgrade to your program: choose apropriate time scale and iterate through binary length of a chosen number size (i.e. 8 bits). If in a given time scale electron reached a counter you set this bit to 1, else you set it to 0. This should make your program return value much faster.

    For anyone who is familiar with this topic, the fact that he went straight for the strontium-90 to generate a truly random number should be no surprise. However, the explanation of how adding the result of N dice rolled tends to a gaussian distribution as N becomes large (aka the law of large numbers) was a digression, and I would have appreciated some discussion on why a radioactive element is necessary versus the "random" number generator embedded in your favorite program. Or even better, what alternatives exist besides radioactive ones.

    People choose 7 because when we think of the word "random" we usually think of "what is the number with the least connotations with it". Which happens to be 7 when it's 1 - 10. When it's 1 - 20 people usually choose either 7, 17, or 19. When it's from 1 - 30 people usually choose 11, 17, or 19. When it's from 1 - 40, people usually choose 17, 19, 29, 31, or 37. Etc.

    • @austinconner2479
      @austinconner2479 6 років тому +2

      The radioactive source is truly random because of the quantum effects you mention. It's true physics is deterministic aside from quantum effects, but as with radiation, quantum effects can affect macroscopic things as well in some cases. In practice, for serious randomness (for example, for cryptography), computers will collect entropy from its environment, ie the exact arrival time of network packets or completion times of hard drive seeks. Like you say maybe these could be predicted in principle if you could know the exact state of the world, but this is practically impossible. Extreme needs (military?) may even put radioactive sources in the computer and use those timings.

    • @angelmendez-rivera351
      @angelmendez-rivera351 5 років тому

      Jeffrey Elliott No, nothing aside from quantum effects can be random. Every classical system is deterministic. The roll of a dice is deterministic. Us being too limited to do the complicated math to know what value will come out of the roll with arbitrary precision does not make it random, it makes it chaotic.

      +Spiritman Productions Because every individual digit also stands for a number. 7 is both a digit and a number, whereas 17 would be a number consisting of two digits (1 and 7). Both would be correct really, but given we're talking about numerical concepts in our head, number is the adequate term.

    The sum of dice does not approach a normal distribution. It is actually an Irwin-Hall distribution. They look similar, but Irwin-Hall has a much flatter top with shorter tails, and is a piecewise polynomial, not exponential.

    6 and a half minutes in, ruffly, he made a communication mistake. He said you can't get a number between 1 and 12 with 2 dice because you cannot get the number one by adding the sums of 2 dice. Well 1 is not a number in between 1 and 12, 1 is the border, it isn't between the borders. Not a math mistake but it was an English mistake.

      +Leather Rebel Justice When people say "between 1 and 10" the vast majority of people mean including 1 and 10. When people mean it to be exclusive, they state it explicitly. I'd argue he's using the common way of saying it rather than the mathematical way.

    • @LEATHERrebelJUSTICE
      @LEATHERrebelJUSTICE 8 років тому

      +DaffyDaffyDaffy33322 They could also mean 7000 and 189 but that isn't what they said. I mean your comment literally made me jump out of my skin. what do you think about that? Many people also use literally to mean metaphorically which would make the word literally useless if it meant both. I bet your own my side with that. So lets not give into common usage making English a less clear language.

    The dice you speak of is a normal one. A dice in a casino for example doesnt have this issue, they are same on every side, including paint used for the numbers and dont have any holes, they even have a sharper edge, which makes the product much more "random" than the usual dice.

    I choose random numbers between one and ten by looking around the room and choosing the number of letters in the first word I see. If I don’t see any words, then just the first word that comes to mind. I realize that this isn’t a uniform distribution, but I am happy with my normal distribution.
