near zero

  A mathematician, a physicist and an engineer are led into a long room. At the other end stands a beautiful naked woman. “When I ring this bell,” she says" you may cross half the space between us. When I ring the bell again, you may again cross half the space between us." Both the mathematician and physicist groan and wander off. “Ah, it’s Zeno’s paradox, we can never actually reach her.” The engineer, waiting for the bell, says “I think I can get close enough.”

    why is there a naked woman?

      For the joke to work.

      Because humanity has no other desires between math and tits apparently.

      Only straight men are mathematicians, physicists and engineers. This is why the joke is framed this way.

      See: responses from OP, valiantly defending his choice to “piss people off”, instead of noticing the joke is just yet another reminder that men are default.

      After all, sexism is over, and STEM isn’t hostile to women/non-heteronormative people. It’s all in our head.

  Also mathematicians: here’s this cool new thing, I called it “infinitesimal”

  In computer engineering we have positive and negative zero.

    Also in Math.

      Unknowingly from the GP, that’s where CE got it from.

      What algebra uses negative 0?

    What do you mean? In two’s complement, there is only one zero.

      IEEE 754 floating point numbers have a signed bit at the front, causing +0 and -0 to exist.

      Specifically I was referring to standard float representation which permits signed zeros. However, other comments provide some interesting examples also.

    And, as a mathematician who has been coding a library to create scaled geometric graphics for his paper, I hate -0.0.

    Seriously, I run every number where sign determines action through a function I call “fix_zero” just because tiny tiny rounding errors pile up in floats, even is numpy.

  Limit x->0 { x } = 0 ? Noway

  • pumpkinseedoil@sh.itjust.works ⁨11⁩ ⁨months⁩ ago

    Wait do you actually say “limit” instead of “limes” in English?

    • something_random_tho@lemmy.world ⁨11⁩ ⁨months⁩ ago

      Yes, as in “Why can’t I hold all these limits?”

      I usually uses lim

    Yeah, I was gonna say... Calculus is all about saying it's infinitely approaching zero so let's assume it is zero.

    source
• KillingTimeItself@lemmy.dbzer0.com ⁨11⁩ ⁨months⁩ ago

  i mean, mathematically speaking, every number that isn’t zero, is further away from zero, than the number before it.

  So there is a point to the statement of “approaching zero” as well “near zero” and “about zero” since 100 probably isn’t about zero.

  Also CS nerds would like to fight you about floating point values.

    Whoa slow down there buddy. Proposing numbers before numbers like they are a given.

    source

    • KillingTimeItself@lemmy.dbzer0.com ⁨11⁩ ⁨months⁩ ago

      as far as we can tell, mathematically, they are a given, and they never stop.

      I’ll wait for you to find the end of pi.
