In the '80s I read a book which started on a beach on a desert island. The premise was an alien microbe taking over creatures which escalates significantly.

Two decades ago I read a lot of the old TOS novels. There was one novel where Spock was captured (on a planet iirc) and made prisoner of a female person/ alien. She equipped him with accessories like an earring or piercing, maybe even a collar. It felt a lot like an author self-insert. Spock even...

One of the fundamental questions that humans since the dawn of time have asked themselves is why are we here?, or how are we here?, how did all this happen to be?

In Spanish, the word 'or' is represented as 'o', with the exception of cases where the following letter starts with 'o' or 'ho' (including accented forms like 'ó' or 'hó'). Numbers also follow this rule if they start with \$8\$ or are exactly \$11\$, because all numbers that start with \$8\$ in S...

I'm trying to solve a two-period two-good consumption problem. Endowment in the two periods is $w_1$ and $w_2$, the interest rate is $\rho$, and total utility is $$ U(x_1, y_1) + \beta U(x_2, y_2)\ . $$ So far I have that for each $t$, total consumption is given by $$ C_t = x_t p_{xt} + y p_{yt...

Batman is obviously an on-topic character for our site. He regularly teams up with or confronts aliens and has awesome technology at his fingertips even if he himself is "just a man in a suit".

Have the semigroups with the following cancellation property been studied? Property: Let $S$ be a semigroup and $x,y\in S$ such that $xz=yz,$ for all $z\in S,$ then $x=y$.

Recall the definition of slope semistability, taken from section 1.2 of Huybrechts and Lehn's "Geometry of Moduli Spaces of Sheaves" book. Let $X$ be a projective $\mathbb{C}$-scheme and $E \in Coh(X)$ of dimension $d = \dim(X)$. The rank of $E$ is defined to be \begin{equation} rk(E) = \frac{\al...

Maimonides rejected the notion that Jews must help financially other Jews to study Torah: All this is wrong.

The U.S. men’s basketball team has been “bullied” in the past because of the size of the players. Generally speaking, Coach Kerr played smaller lineups, and in losing three of their final four games at the World Cup, the U.S. was often gutted on the glass and in the paint. From NY Times "For th...

I met a character called ??? in Cult of the Lamb. They told me they might see me again, depending on how I do (don’t remember the exact words, been a couple days). How do I see them again? Who are they? And is there a way to get their real name?

In Cult of the Lamb, a follower may occasionally dissent if faith is low enough. What are good ways to stop them dissenting, and have them return to the cult? Reeducating them daily just doesn’t do it.

Here's the main question: What doctrine or practice is there to minimize "conceit"? I suppose that canonically "abandoning conceit" can only be attained by an Arahant and therefore a monk, so, it would be alright to answer in that context (the answer needn't be tailored to a lay-person if it ca...

We say that a set $A$ is "good" if $A\subseteq\mathbb{R}$, and for every positive integer $n$, if $a_1,\dots,a_n\in A$, and for every $1\leq i,j\leq n$ with $i\neq j$ we have $a_i\neq a_j$, then $$\sum_{k=1}^{n}a_k=\prod_{k=1}^{n}a_k.$$ I conjecture that there is no "good" set $A$ with $|A|>1$.
