    At about 1:37 in, there's a chart that incorrectly states the First 1000 Prime Numbers. This chart is actually the prime numbers that exist between 1 and 1000, which counts to about 170 primes.

    Prime numbers remind me of the relationship between the entire alphabet and the subset of vowels; it's the many consonants that make up the sound of a word, it's the few vowels that make the letters readable and speakable.

      I have another case of Pythagoras's problem, the problem is such this: sqrt(x-95)=y. Please find the nearest by solution for x integer to 95, therefore it will give y integer solution. For that case, the solutions is x=144, and y=7. we can write the problem as sqrt(x-c)=y. Is there any elegant formula to find x and y for any given c?. x, y, and c is a real integer number, c is an odd number, and x is the nearest number to c that can be squared root.
      if we can find the beautiful, elegant formula, then we find the formula of prime number

    The polynomial n^2 + n + 41 fails for n = 40. When n is 40, n^2 - n + 41 gives the prime 1601, but fails when n = 41.

    Knowing the order of primes, means knowing where all of the patterns of numbers that are divisible by N, X and 1 are not; where N is the number of being divided and X is a number between 1 and N. It is no surprise that you would struggle to come up with a rule that shows EXACTLY how to do that. It is like me having to learn to work around everyone else all the time, without ever getting them to work around me; when it comes to dealing with problems in my life, which would explain why I have so many problems with it and need to get people to learn that I cannot learn to do this!

    I like the way you talk.Thank you for your efforts. You are making math very likable. Ive got a question. Can we say that any positive integer larger than 2 is made of 2^n + some number other than 1 ? Or say, lots of 2s+ some number other than 1? Except 3 as special case offcourse.The reason why i am asking this because thinking about collatz conjecture and goldbach conjecture.

      It depends what you take n to mean. If the number of 2's can be less than the maximum that will divide into the given positive integer then the statement is clearly true.

    I think the goldbach conjecture has to be false, cuz in the reference of the entire infinity, the higher we get the less the density pf prime numbers ( i guess )
    So there must be atleast one number that doesn't follows it

    • @ethanbottomley-mason8447
      @ethanbottomley-mason8447 2 роки тому +1

      We already know for certain (it has been proved), that any even number bigger than 2 can be written as a sum of four primes. With your logic, we would expect this to not be the case. Also, the primes do become more spread out, but not very spread out. About 1 in every ln(n) of the first n numbers are prime, so the number of combinations of possible sums is very large.

    • @samucabrabo
      @samucabrabo 4 роки тому +3

      Yep. It fails trivially for n=41. Usually the formula considered has a plus instead of a minus, so it fails for n=40, because
      40^2+40+41 = 41x40+41 = 41^2

  • @EdMcF1

    Is the interest in primes an artefact of the human mind? I.e. they are just 'numbers' and the issue arises from our classification of them on the basis of an arbitrary designation of being divisible by only 1 and itself?

  • @mahthi5990
    @mahthi5990 4 роки тому +2

    prime numbers are those which are not divisible by any numbers except themselves and 1 so when we divide a prime number with 2 always an odd number is left out as all even numbers are divisible by 2 so every prime number when divided with 2 leaves out an odd number.When two primes are added the left odd numbers can also be added and hence when two odd numbers added it is always an even number and hence all the multiples of 2 can be expressed as the sum of two prime numbers the least being 4

    • @chadgrinder2030
      @chadgrinder2030 4 роки тому +1

      To expand on my previous comment... it could be the case that some even number > 2 cannot be expressed as the sum of two prime numbers but the sum of a prime number and a non-prime odd number. If that is the case, Goldbach’s Conjecture would be false

    I never really understood what is the deal with Goldbach's conjecture. I mean we know that all prime numbers greater then 2 are odd, and the sum of two odd numbers will give you even integer. Wouldn't that prove the Goldbach's conjecture, although it would be for more generalized case?

    I wonder if any mathematician(s) has/have studied the distribution of positive composite numbers that are abundant with respect to having multiple pairs of primes that sum up to them vs. ones that only have one or two such pairs? In order to offset the bias towards positive integers which can be divided by multiple powers of 2, I would limit the scope to positive integers which are divisible by only one power of 2 (e.g.: n|2^1)
