In the sentence 'в какой стране ты живёшь', I don't understand why 'какой' is in the nominative rather than the prepositional case (like стране). Is this a special use of the interrogative pronouns here?

My son has finally shown an interest in Mindstorms and we are trying to use an NXT block with my 2015 Macbook Pro (latest OS) running the EV3 Mindstorms home edition software.

For teaching porpouses, I would like to make a relaxed scan for an A-BC system (for example, the isomerization of of H-NC to H-CN or CH3-NC to CH3-CN) with Gaussian 16 using generalized internal coordinates. In particular, the coordinates to be scanned would be the distance of atom A to the cente...

Does anyone happen to recall the title or author of a science fiction novel with the following major plot elements? My recollection, not a quote: On an alien planet, whose plants are not green (lacking chlorophyll), and thus are less efficient and being outcompeted by introduced Earth plants. L...

In article 23 of his first memoir on biquadratic residues, Gauss gave the first example of a binomial-type congruence, which is apparently a quite "deep" result - many authors relate it to the theory of integral points on certain elliptic curves. His result is stated as: if $p=4n+1$ is a prime, t...

I try to give multiple arguments to a function using a comma seperated list (clist). This seems to work and I can also iterate over the elements by using a seq.

The "Twelve Cities" are mentioned several times in the movie. The Book of Peace is needed to protect these cities, but which cities exactly are they? It's safe to say that Syracuse is one of them, but what are the other eleven? Is "Twelve Cities" a reference to anything real or mythical?

At first there seemed to me to be a grammar error in De Bello Gallico I.11: Helvetii iam per angustias et fines Sequanorum suas copias traduxerant et in Aeduorum fines pervenerant eorumque agros populabantur.

I believe this is basic differential geometry issue. This may be obvious to many, but I was quite confused about it, and it took me quite a while to find the resolution.

One cannot solve the transition amplitude $\langle{x}\vert e^{-iHt}\vert{y}\rangle{}$ with $H=H_0+V$ by just applying the operators one after another on the bra/ket, because the free hamiltonian $H_0$ doesn’t commute with $V$ in general. This gets clear when you expand the exponential operator $e...
