Johann Tetzel was a Saxon Dominican friar and preacher who (in)famously granted indulgences on behalf of the Catholic Church in exchange for money, which were claimed to allow a remission of temporal punishment due to sin. In a book that I have just read (Evening in the Palace of Reason, by James...

I'm following-up on this great answer. Essentially, I was wondering how could misspecification of random-effects bias the estimates of fixed-effects? So, can the same set of fixed-effect coefficients become biased if we create models that only differ in their random-effect specification? Also as ...

A common trope with technologically advanced races is the lack of a need for speech. Machine races that self optimise usually forgo spoken languages all together, instead opting for completely wireless communication. The best example is a race of sentient robots that have modified themselves over...

I was text-chatting to a Spanish-speaking colleague on MS Teams and we both said almost the same thing at the same time - as a British person, my reaction was to say "Snap!" - it's a tradition to say it when you both say the same thing at the same time. I think it's popular in the UK and Australi...

The sum of the binomial coefficients of $(x+y)^n$ can be expressed as follows: $$\sum_{k=0}^n\binom{n}{k}=2^n$$ This can be shown to be the case using a double counting proof of all the ways of choosing subsets of a set of $n$ distinct elements. The alternating version of this sum can be shown to...

What is meant by meditation in Psalm 48:9 and Psalm 104:34? The English word “meditate” evolved its meaning in the mid- to late-1900’s. Previously, it had been more like ”to contemplate”.

I've often seen Lord Shiva with 'half-moon' on his head which, I was told, as the timelessness of Lord Shiva; meaning Lord Shiva is beyond 'time' or he's the master of time and space as per Hindu sources. But why does specifically the 'half-moon' symbolize this?

How would one define all $x,k,r$ in the following? Do I need to define that both $x,k \in \mathbb{R}$ or does just defining that $k \in \mathbb{R}$ naturally imply that $x \in \mathbb{R}$ (or vice versa) simply using the comparison $x > k$?

I've been observing the stars and I have found some lists on internet that sort them by its apparent magnitude (m), so you end up with lists of brightest-stars like this one: https://www.star-facts.com/brightest-stars/ The problem is that I would like to sort them beyond 300 (The maximum amount t...

A permutation of the numbers $1,2,3,\dots,n$ is called cute if there is exactly one number that is greater than its position. For example, $1,4,3,2$ is a cute permutation (when $n=4$) because only the number $4$ is greater than its position. How many cute permutations there for a fixed $n$? The...

I'm working on a custom piece of hardware where a fan is turned on and off automatically. The user can override the decision of the automatic system through a switch. Activating the switch when the fan is on will turn it off, and vice versa. Is it a valid choice to use a toggle switch (see the im...

I am trying to work with the STO-3G basis set, but I noticed that the STO-3G in Basis set exchange is different from the STO-3G originally published, and not only that, the BSE version seem to be significantly worse. I am sure I am doing something wrong, can anyone please point out? (original ref...

Let $M$ and $N$ be topological spaces. Let $\operatorname{Sh}(M)$ denote the presentable $\infty$-category of space-valued sheaves on $M$. It seems to me that the equivalence $$\operatorname{Sh}(M) \otimes \operatorname{Sh}(N) = \operatorname{Sh}(M \times N)$$ where $\otimes$ is the standard symm...

The total wave function of $H_2$ can be written as a linear combination of configurations built from bonding and anti-bonding orbitals: $${\displaystyle \Psi _{\text{MC}}=C_{1}\Phi _{1}+C_{2}\Phi _{2},}$$ where $\Phi_2$ is the electronic configuration $(φ_2)^2$. In this multiconfigurational descr...

Say that you enter into an agreement with a contractor to fix something in your house. He assures you there won't be any repercussions until he can get to it in a couple of days, but before he comes the delayed repair has resulted in damage to your house. Having relied on his expertise to assess ...

I'm still fairly new to the game, and I'm working out the schematics of my character. I play a half-elf character, and I was wondering: can racial bonuses be changed once the characters been made, or during a level up, or not at all? What I mean is, as a half-elf I have a bonus of two different a...

I am a software engineer concerned about current draw. I am aware that there are ways to reduce the current draw of a program, for example: using a hlt instruction which disables the CPU until the next interrupt maybe avoiding floating point so that the FPU doesn't get jiggled I'm wondering i...

I'm doing list of mac addresses. I have used tables but I don't know how to manage the space (before or after) the hexa value. For one device the different mac# are not properly aligned from each other, there is a slight space that depends on the "size" of the hexa value (I mean a "11" value is t...

We had a phone jack in kitchen that we removed. We first cut the line then taped it individually. We noticed the phone line in the basement stopped working afterwards. I'm assuming the basement line is looped through the kitchen line. Is there a way for me to get the basement line restored withou...

As a young teenager, I used to eat pizzas full of jalapenos and Tabasco on them, and very much enjoyed the spicy taste. In my mid-to-late 20s, I started feeling really sick when I ate these, even though at that point, it was far more infrequent. Now, in my post-35 age, I tried making a pizza at h...

The freedom of movement spell states: For the duration, the target's movement is unaffected by difficult terrain, and spells and other magical effects can neither reduce the target's speed nor cause the target to be paralyzed or restrained. [...] Meanwhile, the haste spell states: [...] When t...

Suppose a proof came out (and was verified by credible peer review) of the following statement: There is a $T_0$ such that for all $t>T_0$, all zeros $\zeta(\beta+it)=0$ have $\beta=1/2.$ where $T_0$ is totally ineffective. What interesting consequences would this partial result have? Of cours...

An answer tangentially mentions that there are those who say that one should also bow at the end of the Modim deRabanan. This is mentioned in Orach Chayim 127:1, and its foremost proponent seems to be the Rashba, who reports in the name of the Raavad that the discussion on Berakhot 34b is actuall...

I have this Playstation 2 power supply which was originally run at 110V input. A fellow member of this forum suggested that there might be a good chance that it could a universal input voltage and might work at 220V AC. I have taken a look at the power supply board and I couldn't figure whether t...

It's a very common trope in the Star Trek universe for treatments to the disease du jour to be developed and rolled out very rapidly. Many, if not most, of the main characters or even most of an entire planet's population become ill as the ship's doctor races against time to find "the cure" or "t...

I found a phrase in Russian that said "Снова нам в путь", meaning "We're on our way again". I didn't quite understand why it used the dative Нам instead of the nominative Мы. I tried to translate "Мы в путь" at Yandex and it gives the same translation ("We're on our way") and even some examples. ...

With piano I dont really see/hear the point yet of having slurs because of its sound. I find it difficult to play more legato than is normal. Please can someone enlighten me. Are slurs for piano scores or are they more for other kinds of instruments

My question is about the definition of cointegrated. $y_t =y_{t-1}+u_t$ $u_t =\eta_t +0.5\eta_{t-1}$ where $\eta_t\sim N(0,1)$ is i.i.d. white noise. I claim that $y_t$ and $y_{t-1}$ are cointegrated because $y_t -y_{t-1}=u_t$ is stationary and both $y_t$ and $y_{t-1}$ are non-stationary. Is this...

Let's say I construct an invalid transaction, that wants to spend UTXOs sitting at a script address and send it to the network for validation. The script then validates the transaction and fails so the UTXOs are not spent. Are fees still collected for such a validation? If not is it a possible ve...

Where do I find the official dimensions to draft electrical symbols according to their standard? So far, I've referred to ANSI/ISA-5.1-2009 to draw instrumentation symbols. In it, there is a section that breaks-down the drafting components for each symbol. From these building blocks, you can draw...
