"number"
Conclusion: Javascript is Neutral Evil
Always has been
Now that's a characterization I can get behind!
That is a valid point. Also, I learned something about JavaScript. Thank you!
Well, it's something like the difference between { x: null } and { }.
That's why it's in the Evil row
I feel like it belongs more in the chaotic row
Well, at least it is used in place of a number. But what about QED.?
Pythagoras: Everything that exists is a number. Except irrational numbers. Fuck those things.
X can be a number.
X is a letter.
X is ten, as the Romans do
X is a dying website
X marks the spot.
Let x be any number. => x is a number. QED.
I've taken like four or five advanced trigonometry courses and I still can't really define what trigonometry is. Mathematics is like Andrew Tate's Hustler University scam. If you take one class, it only exists to prove that you're a mark and sell you more classes.
Trig is basically the study of a wiggly line and how it turns out to be useful everywhere
I enjoyed the trigonometry unit in my highschool geometry class, but that's because it was mostly proofs, and those were just philosophy about triangles.
I have a masters in math and I have no fucking idea what a second course in "advanced trigonometry" looks like much less a fifth
Do you have a version without the white lines?
If you change "number" to "vector" you'd have mathematicians agreeing with half of those.
But a vector is a number, no?
A vector is a thing that can be added together and scaled in "the intuitive way." That is, for example, if a and b are numbers and v is a vector, then av + bv = (a+b)v (vector addition distributes over scalar multiplication). The prototypical example is the collection of arrows rooted at the origin on the 2D plane, where addition has a simple geometric interpretation (you put the tail of one vector at the tip of another, the resulting point is the new tip) and scaling is "stretching." But it really could be anything that adds and scales.
Not really.
klein bottle is a number
It's true, my great grandma just turned klein bottle years old
