What is the #probability of being in two different #houses at the time when the central #AC broke? In two different cities. Within a two month period (40 days from start of the 1st failure to the start of the second.)

Seriously, I'd like to know.

Math question: Why is there only one way to assign a number to 1 + 2 + 3 + 4 + 5 + …? This sum is always said to either diverge (with the usual definition of equality) or to equal -1/12. Under normal rules it doesn't have a value, but if you ignore that, then – pretty much independent of what you do – you always get out -1/12. Why never any other value? In what way is this genuinely the correct value for this?

Every year the many names for mathematical statements cause my students a little anxiety. I want to make an Euler diagram to show how they all overlap and intersect— so please mention any words I could add to this list:

statement
proposition
theorem
axiom
postulate
rule
law
definition
formula
corollary
lemma
conjecture
hypothesis

Can you think of any others? #math #mathematics #mathquestion #definition

For a set of N people divided into n-sized groups, what's the minimum number of rounds for everyone to have met everyone else (been in a group with), and what is the list of groups for this? (Ideally, as diverse as possible)

Optimizing speed dating for 52 folks with 4-6 people groupings here :-D

(I know it's an NP-hard problem, but surely for these low values a solution exists?)

Math Question:

What are the conditions for Newton's method to converge?
Specifically: How fine a net of initial values would I need to cast to find all real zeros(in t) of

`` cos(ct) - cos(d)•cos(t0-t)`` ?

c, d and t0 are real numbers.

Does anyone know where I can find some good references for how different cultures did math? Ideally something approachable, and the more unexpected and unusual the better.

This was an interesting reference, and has some elements of what I'm looking for:

#MathQuestion here
x^{y} is just an exponent
x \centerdot 10^{y} is scientific notation
does x^{y^{z}} have a specific name?

How would I convert x^{really fucking big number} to x^{y^{z}}?
