    A mathematical zen koan

    Say you have a dot. That dot explodes into an infinite number of dots. Each of those dots explode into a new infinite number of dots. Each of those dots explode into a new infinite number of dots, ad infinitum. How many dots do you have in total?

    An intuition I had about infinite numbers -- Is it valid?

    There are an infinite number of numbers. You can take those infinite numbers and slice them into an infinite number of infinite slices each of which can be sliced the same way ad infinitum.

    Undergrad The natural numbers and logical consequences of them

    I mean multiplication, division, addition, subtraction of each of the natural numbers

    Looking for movies where mathematics actually matters

    In pi 1998 a 216 digit number is the key to the structure of the universe

    Undergrad The natural numbers and logical consequences of them

    Is there any basis for this outside of set theory?

    Will anyone alive today see a permanent colony on the Moon or Mars?

    The moon was the first other planet we reached. Mars will be the second. The second is nothing and will barely even be remembered compared to the first.

    Undergrad The natural numbers and logical consequences of them

    Dividing them. Such as by 10, 25, 38, and so on.

    Undergrad The natural numbers and logical consequences of them

    The definition of infinity is that it is how many natural numbers there are. You can take those infinite natural numbers and slice them into an infinite number of infinite sets, each of which can then be sliced the same way ad infinitum. What does this mean/imply?

    Math Math major jobs in the space industry

    I’m looking for jobs in the space industry that I can get with a degree in math. Are there any? What are they? Thanks in advance :)

    Undergrad My basic understanding of set theory

    https://en.wikipedia.org/wiki/Axiom_of_infinity This is the best definition of infinity in my opinion, and it is mathematically rigorous

    Agreed

    Undergrad My basic understanding of set theory

    https://en.wikipedia.org/w/index.php?title=Infinity&oldid=1325158009 Up until a few weeks ago, this was the definition as given in the opening sentence. “Infinity is something that is boundless, limitless, endless, or larger than any natural number”

    Undergrad My basic understanding of set theory

    The definition of infinity is that it is something that is larger than any natural number

    History Apollo 11 or Sputnik 1 - which was more significant?

    I’m honestly not sure which one to pick, Sputnik will always be the beginning, yet Apollo 11 was clearly more impressive. I wasn’t old enough to witness either of them (born in 1995.) perhaps someone old enough to remember them both can give the best answer
