Q: Why do we use hypothesis tests instead of just letting people do bayesian updates?

hmmmmmmmApologies if this is a silly question, I don't understand this very well, but I'm wondering why we need to kind of "discretize" our judgements using hypothesis tests. Why can't we just, every time a study is done, have people report the data, and the p-values and effect size, and then report how ...

Q: Probability that every polygon contains almost exactly the expected number of samples

ColinLet's uniformly sample $n$ times from the unit square. Define a polygon contained within the unit square with area $A$. Surely as $n \to \infty$, the probability that the polygon contains at least $\lfloor{nA}\rfloor$ samples and at most $\lceil{nA}\rceil$ samples tends to 1. What I'm interested ...

Q: Why does the heatshield have to be on the outside?

DagelfTo what extent has internal insulation been tested to deal with the heat of re-entry? In the case of Starship, is the existing steel strong enough (to be non-ablative!), or would a different type of material be necessary? The melting point of most steel alloys seem to be right at the limit... can...

Q: Abstract formulation of associativity

markusasSay we are given a binary operation $f$ on a set $X$, that is, $$ f : X \times X \to X. $$ Denote by $\text{Id}$ the identity map on $X$. We say that $f$ is associative if, for all $x, y, z \in X$, we have $$ f(f(x, y), z) = f(x, f(y, z)). $$ I was wondering if there is a more abstract way of for...

Q: How to calculate this improper integral?

FurinaThe problem is to solve this integral: $$\int_{-\infty}^{+\infty}\frac{\cos^3x}{x^2+1}\mathrm dx$$ I have an idea that use this formula: $$\cos3x=4 \cos^3x -3\cos x$$ It might be possible to split the above integral into two parts, and for each of these integrals the Feynman integral can be calcu...

Paul UszakThere are statistical test suites (below) that are commonly used to determine whether a sequence appears to be (pseudo) random. Some of these test suites have a few tests (ent/ent3000), whilst others have over a 100 (NIST STS). All of them assume the same null hypothesis that the samples are fro...
