Considering two continuous probability distributions $q(x)$ and $p(x)$, The Kullback–Leiber divergence is defined as the measure of the information lost when $q(x)$ is used to approximate $p(x)$. \begin{equation*} \mathrm{KL} (p(x)|| q(x)) = \int_{\mathbb{R}} p(x) \ln \frac{p(x)}{q(x)} dx \e...

I am installing a 320 amp service on my new house in Lewis County, Washington and am a little confused as far as how to split the service.

My class 12 maths textbook says addition is a binary function. But I had this experiment which caused a doubt.

If someone is a fan of British culture we call them an Anglophile. French culture, Francophile. Batrachophile, fan of frogs and other amphibians. Astrophile, fan of stars and astronomy. Is there a similar term for people who love jets? Or aviation in general? Jetophile seems awkward.

There seem to be at least two ways of defining measurability in a smooth $n$-manifold $M$, and I want to know if these definitions are equivalent.

I understand that in the equation of motion of a simple harmonic oscillator $\ddot{x} + \omega_0^2 x = 0$, $\omega_0$ has dimension inverse time. Since solutions are of the form $x(t) = A \cos (\omega_0 t + \phi)$, I also understand that $\omega_0$ is an angular frequency, and is often expressed...
