  One reason is because your chromosomes don’t control genital development, your hormones do. So if you’re born with XY chromosomes and your testosterone receptors don’t work then you’ll develop female genitals and a generally female physiology (minus reproductive organs).

  This is all separate from gender expression obviously, but things are hard because the world is complex. If you haven’t seen or experienced this complexity in your life, that’s fine. But don’t diminish the complexity of other’s experiences just because they don’t match your own.

  That’s interesting. What about talking about it as a subject? Would you say maths are my favorite subject in school?

  Is the ending s kept on abbreviations of other singular words ending in s? Or is that unique to maths?

  Sounds more like TF2 crossed with DOTA, which sounds weirdly fun and hella toxic.

  Rigorously, yes. Unambiguously, no. Plenty of words (like continuity) can mean different things in different contexts. The important thing isn’t the word, it’s that the world has a clear definition within the context of a proof. Obviously you want to be able to communicate ideas clearly and so a convention of symbols and terms have been established over time, but conventions can change over time too.

  Natural numbers are used commonly in mathematics across the world. Sequences are fundamental to the field of analysis, and a sequence is a function whose domain is the natural numbers.

  You also need to index sets and those indices are usually natural numbers. Whether you index starting at 0 or 1 is pretty inconsistent, and you end up needing to specify whether or not you include 0 when you talk about the natural numbers.

  I could be completely wrong, but I doubt any of my (US) professors would reference an ISO definition, and may not even know it exists. Mathematicians in my experience are far less concerned about the terminology or symbols used to describe something as long as they’re clearly defined. In fact, they’ll probably make up their own symbology just because it’s slightly more convenient for their proof.

  Nah, man. Pluto doesn’t care any more. Even as a dwarf planet, he knows he’s still hot shit
