>mathematicians can't even agree on whether zero is a natural number This is why no one takes you seriously, mathfags.

Is time travel compatible with determinism?

Why does this happen in LaTeX? How does the typesetter print the text portion of the document correctly, but fail to print any of the math symbols correctly?

post women and their achievements you unironically respect starting with the obvious >Marie Curie >nobel prizes in physics and chemistry she might just be the most decorated female in science

explain this

are there any good sci-fi series out there, lately? recently i got hooked on "the expanse" but hell, where did that genre go? (appart from shitty productions with political correctness aka "we need at least a homosexual and a black on the cast and make the targeted audience 12-16) any good recommendation and in case you didn't watch it: watch it. (it's even close to the books)

MATLAB or python for an aspiring mechanical engineer?

How do I into von Neumann mode? I already got the overeating habit covered

this is like knowing there's two possible answers, but choosing to pick a 100% wrong answer instead.

I'd like to see what everyone else scores on this personality disorder test. If perhaps there's any correlation with neuroticism and intelligence (I like to think rather intelligent people do flock to /sci) http://www.4degreez.com/misc/personality_disorder_test.mv

Why isn't anime real?? Im crying wtf... I just want it to be real so bad but it's not.... why not? Why can't it be real???

Whenever I go to microwave a burrito, I make sure to stand away from the front of the microwave. I'm afraid that some of the microwaves will seep through and energizing my balls. Can someone explain the science behind the safety measures in place with a microwave? How can it be that the sheet with the little holes in them are blocking microwaves 100%?

A friend of mine in the service said when he was stationed in the middle east, his ship would routinely reach temps of 190F. That can't be right? Everything I've read says you'll pass out of hyperthermia within 10 minutes of 130F and higher.

When is /sci/ gonna admit that collectively this whole board has knowledge of biology comparable to an intro course in college and stop feeding into /pol/'s stupid bait? Seriously though, it's just really sad to watch smart people argue with so many terrible assumptions.

To continue, we need tools to examine the projective plane we work with, like circles in ancient Greek geometry. We introduce the most fundamental of those tools here, but before we define it, we need a few definitions. The set of all points incident to a given line is the [math]\textbf{range}[/math] of that line. The set of all lines incident to a given point is the [math]\textbf{pencil}[/math] of that line. In a projective plane, let ranges and pencils be [math]\textbf{incidence sets}[/math]. The incidence sets of the point p and line L can be written as In(,L) and In(p,) respectively. Before we explicitly define this tool, we demonstrate it with the proof of the following theorem: Theorem 2.1: Any two distinct ranges from the same plane have the same cardinality. Proof: We observe that every line has a unique range and vice versa, thus the two resultant lines, which we call A and B, are also distinct. By Axiom 5*, we have a point o not incident to either A or B. Now, consider the following function. [eqn]\begin{align*} Pe : In(,\textup{A}) &\to In(,\textup{B})\\ \textup{a} &\mapsto \textup{B[oa]}. \end{align*}[/eqn] The construction of the points B[o?] for points on A is shown in the pic. If d and e are any distinct points on A, then the lines od and oe are distinct lines which meet at o. Since o does not lie on B, then by Axiom 1, the points B[od] and B[oe] are distinct. Since d and e were arbitrary, then Pe is injective. Now take an arbitrary point x on B. Let z = A[ox]. The point z exists and lies on A, so Pe(z) exists. {z, o, x} is collinear and x lies on B, so Pe(z) = B[oz] = x, thus Pe is surjective. Since Pe is surjective and injective, it is a bijection between In(,A) and In(,B), thus they have the same cardinality. # The function used in the proof above is the tool we seek, which we will formally define in the next large post.
