So this approach seems to be rather popular, particularly among payment processors that provide javascript integrations. The added layer of security that "fields in iframe" brings also supposedly reduces the level of PCI compliance required. Verygoodsecurity, a tokenization service that also offe...

In older D&D lore, most teleportation type spells worked like a short and (almost?) instantaneous transit through the Ethereal Plane. I'm working on a monster species with Succubus ancestry, being able to cast Misty Step. So, does it work via the Ethereal Plane, or is it something entirely differ...

Let $C$ be a (smooth,proper) curve over a field $k$. Let $\operatorname{Div}_C(k)$ be the free abelian group generated by the closed points of $C/k$ and $k(C)^\times$ be the group of rational functions. We have an injective map: $$i \colon \operatorname{Div}_C(k)/k(C)^\times \to \left(\operatorna...

history.howstuffworks.com claims kamikaze pilots were not overly effective. Wikipedia states that there was no noticeable increase in number of ships lost even as kamikaze pilots became more common, and in total it seems they only sunk somewhere between 34 and 57 ships. So it sounds, to my unpr...

Did h2 and h3 change the phonetic reality of an adjacent *e in PIE under any circumstances? Can we treat *a and ā as allophones of *e in PIE?

I try to place the three first description in a multirow enviroment and include a linebreak. But I did not succed in doing this without creating an error. Do you have an idea how I could do this? % page setup \documentclass[a4paper, 11pt]{article} \usepackage[margin=2cm]{geometry} % language \u...

The idea is that the spacecraft would not have a propellant tank on board, but instead would have a huge, spherical propellant tender which the spacecraft could climb around in order to turn. This seems like it would be useful, as the propellant wouldn't have to be turned around with the rest of ...

My cat, Odin, sheds a lot. He mostly sheds when he is nervous, aggressive, or play fighting with my other cat, Bose. Is this a problem? I don't really know what's going on with him. He also seems to shed when he is very scared, and I find a lot of hairs from my cat all around the house. My other ...

There was a cartoon, probably Action Man, several years ago with a central villain (not Dr X) who felt constant pain (but didn't behave like it). He could share/fire/distribute his pain via some kind of black and white lava-lamp-esque energy. I remember he was a very strange villain because in on...

Consider a real massive vector field with lagrangian density $$\begin{align}\mathcal{L}&=-\frac{1}{4}(\partial_\mu A_\nu-\partial_\nu A_\mu)(\partial^\mu A^\nu-\partial^\nu A^\mu)+\frac{1}{2}m^2 A^\mu A_\mu\\&=-\frac{1}{2}(\partial_\mu A_\nu-\partial_\nu A_\mu)\partial^\mu A^\nu+\frac{1}{2}m^2 A^...

Does the thermal noise voltage formula: \$ V_n=\sqrt{4kTBR} \$ apply even if the impedance is not matched, or is the noise power formula of \$N=kTB\$ the one that applies even if the impedance is not matched? (k=boltzmann const, T=temp, B=bandwidth.) I'm confused if the thermal noise voltage for...
