Anyone familiar with what type of screw bit driver I need for this?

I have a very rough idea for a setting where humanity discovers that stars, in fact, burn out much quicker than we imagined, so a human colony is stuck orbiting one of the last remaining stars in Galaxy (I like the idea of humanity surviving during heat death of the universe, but the time frame o...

Let $R, X$ be topological spaces, with $X$ path connected and locally path connected, and let $p:R \rightarrow X$ be a continuous surjective map such that every $x \in X$ has an open neighborhood $A$ having the property that the restriction of $p$ to each path component $C$ of $p^{-1}(A)$ is a ho...

In high school I loved math intensely, but mostly due to a desire to win over others: I was average /below average in other subjects, and my math was way beyond the second in my grade (Back then I could earn 8/15 in the AIME contest and everyone else in my school couldn't do a single question). I...

I have a custom sensor I am building and I want to try and filter out the noise. The sensor changes its values when a force is applied, otherwise, if no force is present the signal is flat. I want to filter out noise that may be present. I am using an Arduino Nano Every to read the signal from a ...

I was recently playing in a small local tournament with some amateur players. In one game, my opponent made a move then got up for a walk around the playing hall, but did not press his clock. He is a younger player and it was obvious that he had simply forgotten. After a couple of minutes of thou...

I read this book as a child, somewhere in the late 1980s to the early 1990s. I'm fairly certain that it was labeled as YA fiction. It was a paperback that I think I acquired at a neighbor's yard sale (she had grandchildren, so that doesn't necessarily date it as being that much older). A girl (I ...

The Cartesian plane can be tiled with increasingly large squares like so: This tiling can be generated by starting with a square of side length 1, placed at the origin 0, 0, and then repeatedly adding a square to the side of the resulting rectangle anticlockwise of the previous square, starting ...

I’m working in a very small school environment. They’re on M365 A3 licenses and using Entra along with InTune for mdm. We have (at least in theory) disabled all MFA so that all users (specifically for the students) can just sign in without needing to use Authenticator. The issue is some students ...

Installing a smart doorbell which specifies 16VAC to 24VAC with 30VA capacity range of acceptable power input. Consequently I removed the old 16VAC with 10VA capacity transformer and installed a new 24VAC with 40VA capacity transformer. But before connecting the transformer to the (expensive) sma...

My player likes to use Faerie fire outside of combat, and the spell calls for a dex saving throw. Example: if I'm hiding a mimic and my player casts this spell, I would have to roll dice for the dex saving throw for the mimic. Now that I did roll dice, my player would know that there's a creature...

So I was reading an article about the Concordia sailplane (http://lesgpr.free.fr/construire/concordia/ConcImagine_WV_e.pdf) and one graph on page 5 caught my attention. It shows there's a slight dip of Cl at around 5 deg AoA. The HQ 17 airfoil used on ASW22 has a similar trend. My intuition say...

From this: Normal mode oscillations. If the Hamiltonian turns out to be a quadratic function of coordinates and momenta for a system of $N$ objects, e.g. $$H=\sum_{ij} M_{ij} q_i q_j + \sum_{ij} M_{ij} p_i p_j$$ then you can simply do a canonical transformation along the eigenvectors of $M_{ij}$...

I have an application in Android (version 6, so quite old) whose communication I want to monitor. I have installed my own root certificate in the user store and Android warns me correctly that data can be monitored. I have access to my WiFi AP and have captured packets from there, which when load...

I know the following two sentences are correct: 1. The cow is a useful animal. 2. The lion is the king of animals. In this case, cows and lions are represented as categories of animals. The definite article is used, but no specific reference is meant. Also, the sentences are definitions of the ca...

I try to solve the following problem: Let $M$ be the midpoint of $[AB]$ and $EB = AD$. Then we have to prove that : $\widehat{ADM}= \widehat{MEB}$ (without using congruent triangles and trigonometry). My idea is to use alternate or corresponding angles and parallelism properties. Also maybe I wi...

I'm working on a creative writing project. I researched a bit into Uranus and it's near 90 degree tilt. I was wondering if a rocky planet can have the same kind of axis rotation while also being tidally-locked. If so, then can the planet have an orbiting moon too?

I am studying regression in Wooldridge's Econometric Analysis. The regressors are treated as random. He says that a basic assumption for consistency of the least squares estimates is the "population orthognality condition" ("Assumption OLS.1"), which is $$ E(x'u)=0. $$ The linear model here is $y...

I want to make an inquiry into why people commonly use \begin{tikzpicture} and \end{tikzpicture}, instead of just \tikz{}. The reason for me asking is that I would prefer when making an MWE to use the smaller syntax, as it is less cumbersome to type. Most posts declare the environment using the \...

I would like to display the integer 321 as 00321. Fortunately, someone already thought of that: PaddedForm[expr,n] prints with all numbers in expr padded to leave room for a total of n digits. Here we go: (* NumberPadding has no effect on the result except *) (* for making character positions v...

I'll get straight to the point: On one planet of this vast universe, there is a sapient species who, despite being around for even longer than humans have, has not had any technological development besides basic wooden tools, like native Americans used. My explanation for this is that their plane...

Problem statement: Let $\triangle ABC$ be a right triangle with $B=\frac{\pi}{2}$ and a unit square sitting inside the triangle as shown in the image below. Find the length of the side $AB$ The only solution I could think of was: By the Pythagorean theorem $$AB^2=AC^2-BC^2\iff(y+1)^2+(x+1)^2=4...

When low or intermediate mass stars die, they collapse into white dwarves. When high mass stars die, they go supernova and their cores collapse into neutron stars or black holes. However, if a white dwarf accrues enough mass by pulling mass off of another star beyond a critical mass, a runaway th...

I created contour lines in QGIS with a 50m spacing and also styled the interval lines (every 250m) using this expression: if("ELEV" % 250 = 0, 0.5, 0.1) This works fine, but when I add labels they don't appear for the interval lines, only regular (in-between) contours. I only want labels for the ...

I read this in Asimov's in the early 80s. A movie projectionist realizes that the films he's showing have strange subliminal images (alien faces - football-shaped and words). He reports this to his boss and is fired (the boss has already succumbed, I think). He ends up fleeing and hoping to resis...

How often do you rewrite or significantly alter chapters of a work, completely changing the narrative or perspective of the story? For example, creating a completely different chapter if something isn’t working as planned. One example of this is J.K. Rowling, who made several changes to the first...

Suppose that you have some avocados, and that the avocados are under-ripe and hard. Suppose that we leave the peel on, so that the green flesh of the avocado does not oxidize and turn brown.

I don't understand why one cannot find the true values of the parameters α and β in the linear regression model. Why must they always be estimated? I read it has something to do with the error term containing other variables ($x_2,x_3 ...$), but I don't fully understand it.

I am a Physics undergrad who wants to be a mathematician. I am thinking of doing a Reading project in a pure math topic under a prof, for the sake of knowledge itself and also to build my profile.

When citing a book, espcially a large one, is it better to also mention the chapter of the book so that it is easier to find? How is it usually done? My field is computer science if that matters. Papers that I have seen generally doesn't mention chapter name/number when citing books. They just se...

How to find Texel Density Value in Geometry nodes. Since there no UV Area Node it seems impossible.

Within the modeler I want to merge vector layers after processing them (similar to this question), but the layers are optional. At least one is handed to the model (otherwise it wouldn't be run), but there may be up to four layers in any combination. Any processing of the optional layers is depen...

Or to ask the same question differently: given a public key, what length of fingerprint is sufficient for checking purposes such th...

From what I understand, PCB manufacturing has a limitation on the minimum width of the solder resist—it cannot be too thin, typically not less than 5 mil. In many components, including those with a 0.65 mm pitch, the spacing between pads can become smaller than 5 mil. This reduction in spacing is...
