There will be a cultural based festival, and I was invited to that. But from my religious point of view it's 100% against of my principles.

Hosea 4:11 reads (NKJV, emphasis added): “Harlotry, wine, and new wine enslave the heart. What's the difference between "wine" and "new wine"? Is it that "wine" is alcoholic while "new wine" is not, or is there a different distinction?

If we have two events $A$ and $B$ it is sure that $$P(A\mid B) + P(A^C\mid B) = 1$$ however it seems me that $P(A\mid B) + P(A \mid B^C) = 1$ is false in general I don't remember why it is so. Can you show me this fact in a simplest way?

I myself work as a clinician-scientists. I work in a small group and oversee several students. The current situation involves one of them who is a PhD-candidate. She is bright, fast and hard-working. Over the past two years, she wrote several good papers. Many of these papers are based on existin...

I am using the quantikz package to draw a quantum circuit and I am failing to insert my "own" gate (BS) as a quantum gate. The gate noisy is a working example of what I want to insert in the second gate. Can anyone help me? \documentclass{article} \usepackage{tikz} \usetikzlibrary{quantikz} \tik...

I would like to add an outlet to my deck -- there is no power there and running an extension cord around the house to another exterior outlet is a total bummer. I actually have relatively convenient access to run the wire right now so I'm not worries about that, but I don't know if adding an exte...

Let $K$ be a field with $\mathrm{char}\,K=0$, $\hat{L}_n$ the complete free Lie algebra of $n$ variables $x_1,\dotsc,x_n$ and $\mathrm{exp}(\hat{L}_n)$ its associated group with the product given by BCH formula (which is the Malcev completion of the free group). Is $\mathrm{exp}(\hat{L}_n)$ gener...

Let $G$ be a directed graph with no multiple edges or loops and let $P_i$ be its vertices. Let $A$ be the corresponding adjacency matrix of $G$, i.e. $a_{i,j}=1$ if and only if there is a directed edge from $P_i$ to $P_j$, ($a_{i,j}=0$ otherwise). Suppose that there is a path in $G$ that does ...

I recently bought my first Smart TV (Philips 65OLED707/12) and I was wondering if I could connect one (or preferably two) microphones to it, to sing Karaoke with my family and friends. I want to be able to mix the sound from the microphones and the sound of the karaoke app, so all is outputted by...

F is a singular distribution function concentrated on the positive half-line. Is it possible that 2-fold convolution F*F is an absolutely continuous distribution function? Please, give me an example.

Let's say you want to generate all images of size NxN, black/white pixels. This is equivalent to counting from 0 to 2^(N^2)-1. On a classical computer, this is impossible for even 32x32=1024 bits. Can a quantum computer count up by 1 faster than a classical computer?

Could I buy a Cessna 172 or a similar plane, take it apart into as many pieces as I safely could without damaging it, rebuild it, and register it as amateur-built? Assume that I know what I'm doing but do not have an A&P certificate.

Steps: I am loading a aprx from a template, which is in WGS84 spatial reference. Then I do some processes. Finally, I want to change the MAP's spatial reference (WGS84) to another, which I get from another layer. It is possible to do it using arcpy and ArcGIS Pro? The code is: aprx = arcpy.mp.A...
