I am writing some lisp code and I would like it not to mess with the global variables in the system. I am therefore being very careful to only use variables within the scope of the let special form. However, as the code gets longer, it becomes harder to make sure this principle is being fully r...

I have a round junction box protruding from an exterior wall. It had a fixture on it with a circular cover, but I've replaced it with a fixture that has a rectangular box which I would guess is supposed to be tight to a wall (see photo). The area where this is installed is covered, but there is f...

I am considering the integral $$ I(y \mid \mu, \sigma) = \int_y^1 \frac{\exp \left\{ \frac{-1}{2\sigma^2}[\textrm{logit}(x)-\mu)]^2 \right\}}{\sigma \sqrt{2\pi} (1-x)}\textrm{d}x$$ which for $y=0$ is the expectation of a random variable $X$ such that $X \sim \textrm{logit-Normal}(\mu, \sigma^2)$...

RealVNC only provides a 32bit app for Raspberry Pi OS (32bit) and not a 64bit native application, at least for now.

I have twice before had a game in which, for story reasons, I wanted to kill the entire party all in one go. Once because I needed the players to enter the afterlife, the second because I wanted the players to be resurrected a while later in the future. In a "traditional" rpg where the GM is go...

My "bad" dog is crate trained for bed. At night he's great, but not when he goes in there for naps--he doesn't nap, he just goes crazy. He's mostly focused on my "good" dog (who does not need to be in her crate). I tried putting my "good" dog in her crate, but that didn't change the "bad" dog's b...

I just read the mechanics for dice rolling in Vampire: the Masquerade 5th edition and something is bothering me. It seems to me that the larger your dicepool is, the more likely it is to get a messy critical. Just in case somebody wants to answer without knowing the rules, here is a very brief ru...

My local bicycle mechanic advised me to get mudguards (such as the ones in Image 1) to extend the life of my drivetrain and protect it from spray in the winter. Would I be better substituting a chainguard (see Image 2) instead of a front mudguard? Would this be lighter and provide the drivetrain ...

Whilst solving a problem, the following system of non-linear equations arose: $$0= \frac{1}{x^2}-\frac{1}{(y-x)^2}-\frac{1}{(1-x)^2}$$ $$0= \frac{1}{y^2}+\frac{1}{(y-x)^2}-\frac{1}{(1-y)^2}$$ I have tried to solve it via brute force and by trying to add them both in a way that could give me the a...

i'm not too sure if a setting or update has changed the quality of my photos, or if the glass lens protector I have put on may be causing this.

I noticed as I set out on this project that there are already a remarkable number of references at ELU to the words here in question. But what can I do?

I live in northern Mississippi, where I think it is usually fine to have already planted pea plants. I did so and they have recently started coming up and are still very small (less than an inch tall). Unfortunately, we are supposed to have extremely cold (for Mississippi) weather coming up, with...

In most introductory courses to category theory, the precise definition of a set is more-or-less ignored. The idea being that all basic results in the subject hold for any reasonable definition of a set. At some point one feels that this must cease to be the case. So what is the simplest (a simpl...

This Question stems from Ronald Fishers Tea problem in how to design experiments which I have reworded.

Kent Haines describes the game of Integer Solitaire, which I find to be excellent for young kids learning arithmetic. I'm sure they will be motivated by this game to get a lot of practice.

While browsing SkyVector I came across these double Class B airspace limits within the same section (is that what you call it?). I'm wondering what it means and what the difference is between this and FL145/SFC.

They wrote several books but the books were not a series. The one book that stands out in my mind was about 2 teen or pre-teen people on different planets that were able to communicate psychically with each other. Another book, a bit less unique about a young psychic boy being chased by an invest...

Solve for $x$ in $$\log_{2}(2^{x-1}+3^{x+1}) = 2x-\log_{2}(3^x)$$ I simplified by doing: $$\log_{2}(3^x \cdot 2^{x-1} + 3^{2x+1}) = 2x$$ $$\frac{6^x}{2} + 3^{2x+1} = 2^{2x}$$ $$6^x + 2 \cdot 3^{2x+1} = 2^{2x+1}$$ Where do I go from here?

I'm currently reading about Peano's axiom and the construction of the natural numbers. The fifth Axiom of Peano does not make sense to me: If a subset $T$ contains $0$ as an element and for all $n \in T$, $s(n)$ is also in $T$, then $T$ is the set of Natural numbers $\mathbb{N}$. I know that th...

I have found a conjecture in a research article on number theory, which is not well known but very reasonable.

Let $X_1,X_2,X_3,..,X_n,X_{n+1}$ be random samples from $N(\mu,1)$. Let us define $\bar {X}_n = \frac{\sum X_i}{n}$ and $T = \frac{1}{2}(\bar {X}_n + X_{n+1})$. It is required to test whether $T$ is consistent and unbiased for $\mu$. We can clearly see that T is unbiased for $\mu$. For testing th...

I live in central India and I haven't met many people who only worship one particular deity or God. They may be partial to one over others, but they worship all dieties.

I apologize if I am splitting hairs here. First of all, is a poset a set? The official definition on my textbook says, If $X$ is a set and $R$ is an ordering on $X$, the pair $(X, R)$ is called an ordered set. I mean a poset is a set with a partial order, whereas a set itself, by definition, ...

Let $\mathcal C$ be a finitely complete, finitely cocomplete category. Then the following are equivalent: $\mathcal C$ is regularly well-powered (i.e. every $C \in \mathcal C$ has a small set of regular subobjects); $\mathcal C$ is regularly co-well-powered (i.e. $\mathcal C^{op}$ is regularly ...

Given two strings a and b, count how many times b occurs as a substring in a, but only when it overlaps with another instance of b.

$\sqrt{-1}$ $\times$ $\sqrt{-1}$ does not follow the path $\sqrt{A}$ $\times$ $\sqrt{B}$ = $\sqrt{AB}$ else the result would be 1. I know (?) that we must first respect that the initial numbers become imaginary, and of course $i^{2} $ is -1. This came up in school (high school) yesterday, a tea...

In Timothy Bays' excellent article on Skolem's paradox, I have been stumped by the following lines: Let's grant that the specific element which serves as “the empty set” will not remain constant as we move from one model of set theory to another—with the empty set in the first model becoming, pe...

Consider a cylinder that rolls without sliding on an inclined plane.

I cannot understand how is $\langle 1 \rangle$ the creator of $(\mathbb{Z},+)$. I know that this element can create all-natural numbers, simply by adding-1 a certain amount of times, but the negative numbers cannot be created.

Why was the name of Pontius Pilate included in the Niceno-Constantinopolitan Creed? Why was it important to mention his name in the creed?

If we have an annual rate of return of 7% for our stock investment, how much is the monthly rate?
