I am trying to properly place the Wifi router and AT&T gateway with 'Structured Media Enclosure' (essentially a metal box) and having a heck of a time arranging an otherwise basic setup.

I'm wondering whether the quaternions are Morita equivalent to the real numbers. The characterisation in terms of full idempotents seems unwieldly.

Correct me please. As far as I know the magnetic flux density B is a function of current, core permeability and its geometry. So let's take a power transformer rated to S VA.

A common definition for the limit point of a sequence is that a number $x$ is a limit point of the sequence $(x_n)_{n\in \mathbb{N}}$ if there exists a subsequence that converges to $x$. Intuitively, it appears that if a sequence has no limit points then for some $N$ the sequence is monotonic for...

As a child I was big into reading, and very quickly sci-fi & fantasy became my go to genres.

In tradition, kobolds were fey creatures associated with mischief, similar in appearance to gnomes or gremlins, often with the ability to become invisible (like the kobold Pumuckl popularized in a German TV-series).
