In the 1971 movie Willy Wonka and the Chocolate Factory, Willy Wonka says Charlie stole Fizzy Lifting Drinks. But was it really stealing? Admittedly, Mr. Wonka did not offer it to them but he also didn't prohibit them either. He was very generous with all other aspects during the tour and offered...

Trying to find a book I read years ago. The main premise was that clones were used for people to live on Earth while the original person retired on the moon. There were two main characters. One was an older author who was wanting to retire. She made a clone of herself to live on Earth and continu...

While looking through a high school calculus test, I came across a question I didn't know how to solve (using only high school calculus). The question was along the lines of: What is the volume of the shape created by taking the region of the $xy$-plane bounded by $y=x^2$, $y=0$, and $x=2$, and ...

I have a rather long computation, and I'd like to store it in a local variable, so I can operate on it, in multiple different ways for a small GUI in Mathematica. Here's an example that demonstrates the problem: DynamicModule[{input1 = 0, input2 = 0, result}, Dynamic[result = Sum[Prime[i...

In Leary & Kristiansen I was reading about how the compactness theorem can by used to show there are non-standard models of arithmetic. The example was that if $\Sigma$ is a set of $\mathcal L_{NT}$-sentences (number theory), let $\Theta$ be a new collection of sentences in the language $\mathcal...

In Shir HaShirim (5:11), Rashi writes: "רְבָבוֹת הַרְבֵּה קְרוּיִין רְבָבָה, שֶׁנֶּאֱמַר "רְבָבָה כְּצֶמַח הַשָׂדֶה נְתַתִּיךְ": Many myriads are called ‘רְבָבָה’, as it is stated, “Myriads רְבָבָה like the vegetation of the field have I made you.” So the plural word רְבָבוֹת becomes singular (רְ...

It's been a bad day. This morning I attempted to upgrade from 22.04 LTS to 24.04.01. It didn't go well. My machine is a Lenovo ThinkBook 13s G2 13.3" WUXGA, with 512Gb SSD. It dual boots Windows and Ubuntu 22.04. I assume because of flakey wifi, the upgrade process aborted with the message: ⋮ Cou...

I replaced a 30 amp double breaker (one unit with two switches tied together) with a 40 amp of the same kind to install a tankless unit.

On a recent shiur, a Rov mentioned that one is supposed to spend up to a fifth (20%) more on goods or services provided by a fellow Jew. So for example, if you're in a Jewish bookstore and they're selling a book that's a couple dollars cheaper on Amazon, it would be preferable to purchase it from...

The question is if $\cos \theta = \frac{2}{3}$ and $270^\circ < \theta < 360^\circ$, then determine the exact value of $\frac{1}{\cot \theta}$. First observation is that $\theta$ must lie in Quadrant IV. $\frac{2}{3}$ is not easily identified on a unit circle. $\frac{2}{3}$ of the way between $27...

The belief that there is somehow a fundamental, essential, or irreducible distinction between the so-called first-person and the third-person perspectives on consciousness seems to me a metaphysical dogma that prevents those who adhere to it from developing (or coming to an agreement about) a sci...

I am making a constructed language for a vespid-humanoid species, Ictuk.

I have the following scenario in mind. Act A repealed Act B. Act C repeals Act A. What happens to Act B — does it remain repealed? Let's assume that Act C doesn't mention anything about Act B. This is a practical example, as The Statute Law Revision Act 1861 repealed several hundred statutes, but...

Let $\theta$ be a Gaussian variable with mean 0 and variance 1. Then for $t>0$, the variable $\theta \sqrt{t}$ is also Gaussian with mean $0$ and variance $t$. Let $|\psi_0\rangle$ be an arbitrary state on a Bloch sphere. Define $$|\psi(t)\rangle := R_x(\theta \sqrt{t}) |\psi_0\rangle$$ where $R_...

After watching the amazing footage of the Apollo 13 capsule parachuting down on the ocean, I was intrigued by how NASA predicted when and where it would splashdown on the vast ocean's surface with amazing precision.

Every site and AI and Google say that one way of measuring a galaxy's diameter is in terms of its isophotal diameter, using the blue D25 standard, using units of, "25 mag per arcsec2". But magnitude in astrophysics is a relative standard, so to speak, so... How much brightness is '25 magnitudes'?

It is easy to mathematically describe the motion of a mass which is attached to a spring and also pushed around by a sinusoidal force. We get a differential equation of the form: $$\frac{\mathrm{d}^2x}{\mathrm{d}t^2}=-\omega^2x+A\cos(\omega't)$$ Applying the Fourier transform to this and integrat...

I am a CS PhD student who recently published a review paper in an MDPI journal, following my supervisor’s recommendation. After publishing, I learned from peers that MDPI is considered predatory.

I'm in Pennsylvania (US). We recently had a patio installed and I chose to do the electrical myself. I've done tons and tons of residential electrical, including weatherproof outdoor receptacles, but those were wired through the back attached to the home.

If $0\leq c_k\leq 1$ and $n$ is any positive integer, then is $$\frac{n\prod_{k=1}^nc_k}{1+n\prod_{k=1}^nc_k}\leq \sum_{k=1}^n\frac{c_k}{1+c_k}?$$ It is true for at least one of the $c_k=0$ and is also true if all $c_k'$s are equal. Please suggest if this inequality already exists in the literat...

$\DeclareMathOperator{Hom}{Hom}$ $\DeclareMathOperator{Ext}{Ext}$ Given a nonabelian finite simple group $G$, how to prove that: $H_1(G)=H^1(G)=H^2(G)=0$? I know that $H_1(G)=G/[G,G]$ is the abelianization of $G$, which vanishes as $G$ is nonabelian and simple. By Universal coeffient theorem, $H^...

First a little about me and why I have this question. I'm a non-native speaker of the Chinese language.

When air close to a glacier surface gets cooled, it becomes heavier and flows down the glacier slope as glacier winds. I am a glaciologist trying to study and model glacier winds.

Background The Hebrew bible and New Testament make numerous references to the concept of marriage (Exodus 21:10; Genesis 2:24) and even include stories involving weddings such as the famous Wedding at Cana. The NT also includes numerous commands for married couples such as Ephesians 5:22-33. Howe...

This specific question as to Acts 1,24 has not yet been treated in this forum. We have general discussions on the usage of Jehovah in the NT but not with a primary focus on this verse.

Let $\mathcal{H}$ be a Hilbert space. I am very well aware of the fact that the sum of two (possibly unbounded) self-adjoint operators is in general not self-adjoint, in fact not even densely-defined in general. However, lets say $A:\mathcal{D}(A)\to\mathcal{H}$ is a closed, densely-defined opera...

A low value* - but very useful - bike of mine was stolen the other day. The D lock (Kryptolok Series 2) I'd put through both seat stays and the back wheel was squeezed. Locking this way means there's too much bike in the way to get a bottle jack in there and jack it outwards. The lock mechanism...
