At the end of the story, Poirot exposed the real love triangle. "It was the eternal triangle all right! But you saw it the wrong way round. Neither of those two men cared in the least for Valentine Chantry." ... "They planned to ‘meet’ here and stage their crime." I can see that Tony Chantry di...

In R, I have a sf point layer called maps_stations_pts. I created circular buffers of radius 10 km like this: # create 10 km circular buffer maps10km <- st_buffer(st_transform(maps_stations_pts, 3857), dist = 10000) # converting to CRS 3857 for meters st_write(maps10km, "d:/tomas/ces/data/ndvi/MA...

I've come to believe that continuous refactoring is a good way to maintain the health of a system that is in continuous development. That is, a system for which new features are always in the pipeline. By 'continuous refactoring' I mean to make small updates to code surrounding the new feature be...

It is common knowledge that the abelian group $\mathbb{R}$ forms a vector space over the field $\mathbb{R}$ with scalar multiplication coming from the product in $\mathbb{R}$. My question is: is there any other scalar multiplication $\cdot: \mathbb{R} \times \mathbb{R} \to \mathbb{R}$ making $\ma...

This relay has the following max contact voltage, current and power ratings: Now focusing on the DC switching from the datasheet, the max switching current is 10A and max switching voltage is 30V. But the max power would be 10A×30V = 300W but it is given as 240W. So does that mean how we interpr...

He claims he suffers from a rare form of chronic fatigue syndrome that has created problems with short...

Gibson and Sterling's The Difference Engine focuses on changes due to Babbage's success in creating a mechanical programmable computer in 1824, but there are signs of earlier differences with our history*. Did the authors ever discuss where they thought the key change (if any) occurred (if have m...

I just to watch (in UK) a series I’m pretty sure it was mid 90s. It was on late at night. The basic premise from what I remember was a small crew I think on human male and an android that was a sexbot perviously. I can’t remember if he rescues her or something and they steal a space ship. It was ...

I've set up a domain for a friend (maple-tree.co.uk). He wants to be able to send and receive email at this domain, and it seems to be working, mostly, but not fully. Some mail servers (BTInternet in particular) won't send email to this domain. I think the problem is likely related to DMARC and M...

This is taking much longer to plot than I would expect: Plot[ r BesselJ[0, BesselJZero[0, 3] r]* BesselJ[0, BesselJZero[0, 2] r] , {r, 0, 1}, Filling -> 0, FillingStyle -> {Orange, Blue} ] it is about 2.5 seconds in my machine. Whereas Plot[ Cos[4 Pi r]* Cos[6 Pi r] , {r, 0, 1}, Fi...

We ran into an issue with pycoQC this week that we spent a stupid amount of time resolving. Someone reported a related issue on the pycoQC GitHub that wasn't fixed because the software is no longer supported. We figured out the problem, but since the repository is archived, I can't post our issue...

My first time gate asking a question. I was taught once by a Bible teacher that the word for “rib” in Gen 2:22 meant something curved. She understood that to be something curved was taken from Adam’s side to make the woman, meaning Adam’s DNA. Since it says male and female He created him, and it...

At the end of chapter 28, "The Exposure of Stephanie", in Theodore Dreiser's novel The Titan, there is the following passage: “D— her!” he exclaimed. “D— the little beast, anyhow! The ——! The ——!” He used terms so hard, so vile, so sad, all because he knew for once what it was to love and lose—t...

I am studying the behavior of solutions to the differential equation $$y'(t) = y^{2-\beta} \ln(y(t))$$ where $\beta \in (1,2)$ and $0 < y(t) < 1$. I am particularly interested in proving whether the solution touches the $ t$-axis, i.e., whether there exists a finite $t^*$ such that $y(t^*) = 0$. ...

Plot/Setting Details: I remember very little about the actual plot of this book other than some very peculiar world-building details.

Suppose I have a topological group $G$ and a $G$-space $X$. I would like to define the homotopy quotient $X_G$. I have heard of two ways I might be able to do this: Define $X_G$ by the Borel construction $X_G = (X \times EG) / G$, Define $X_G$ by taking the homotopy coequalizer of $G \times X \r...

Consider the following high school problem: For some arbitrary constants $c_1,c_2$, find all $p$ such that \begin{align} c_2\sin{p}+c_1\cos{p}-c_1&=0\\ c_1 p\sin{p}-c_2p\cos{p}+c_2p &=0 \end{align} A student in class did the following: Clearly $p=0$ is a solution. Now assume $p\ne 0$. Multiply...

I have an object that I need to shorten, specifically the tail of a dragon, and I want to make the back third a little shorter.

I submitted my husband’s and my Schengen visa application, but after a few weeks, I noticed that I had booked a single bed for only one person in our accommodation. Unfortunately, the VFS agent didn’t notice it either. Do you think this will affect our visa application?

Consider the case shown on the left in the given image. Let us assume that the walls are adiabatic. Now I suddenly remove $M_2$. Since there is a net acceleration on $M_1$, it moves upwards and the gas expands. As the gas expands, its pressure decreases and hence, the acceleration on $M_1$. Hence...
