What is a woman?

Is the lack of Y-chromosome a good indicator that someone is a woman? How do you tell qualitatively?

What's /sci/ opinion on molecular biology? Thinking of pursuing that route, I like it but I'm completely clueless about the job prospects

The infinitist schizos who think ZFC is enough to characterize what a set is and enough to base whole mathematics on must not have heard of compactness theorem in first order logic.
Provided ZFC is consistent (an already extremely dubious assumption), the universe of sets which satisfies ZFC axioms may have
1. Infinite natural numbers. I.e. natural numbers that are larger than 1,2,3,4,5,6....
2. Infinitesimal rational numbers (i.e. rational numbers x such that 0<x<1/n for all n (INCLUDING n infinitely large)).
3. The set {{{....}}}} (i.e. a set whose only element is a set whose only element is a set and so on ad infinitum). Contrary to popular belief, the axiom of regularity does not prohibit such sets.
4. Countably many real numbers
These schizos will look you straight into the eyes and tell you that they don't need to tell you what a set is, and that ZFC is enough.

kind of a gross question about blood composition and blood loss

No.14387982 ViewReplyOriginalReport
If someone gets shrek'd and loses lets say 1L of blood just to make it even, how would it be different in composition to 1L of blood which is just circulating normally in a healthy person who isn't bleeding? Obviously it will have the same components but what about in terms of the proportions and concentrations of each component per L?

Nasty problem

No.14381696 ViewReplyOriginalReport
Hi there, I stumbled across this problem at work, if solved it will simplify my work quite heavily.

Is it possible to find the radius of a circle having only the length of 2 parallel chords?

(the problem originally is 3d, find the sphere radius having only the parallel inscribed discs)
Any hint is greatly appreciated
