Say you have a situation where you are trying to mitigate multiple factors from competing sides, but when you make decisions you have to consider both sides, you can't just consider one side as it may have a worse outcome on the other side. So for example, say you were stuck on a deserted island ...

I have my bike (bought in mid-2019) sitting idle for over a year due to covid, as I went back to my hometown and left my bike in my office parking. Before leaving I refueled by bike with premium fuel all the way to the top to stop any rusting in the tank. I had a talk with a few people and they t...

I came across this problem while doing some simplifications. So, I like to ask QUESTION. Is there a closed formula for the evaluation of this series? $$\sum_{(a,b)=1}\frac{\cos\left(\frac{a}b\right)}{a^2b^2}$$ where the sum runs over all pairs of positive integers that are relatively prime.

I want to create a .deb file for Cozy (https://github.com/geigi/cozy) from its github repository. How do I make it? Don't want to use the flathub version. I'm on Ubuntu 20.04.

I have this photo which I am happy with. And I would not be able to find puffins everyday so difficult to reshoot the image. The focus of the bird is on its tail and not the eye. Is it a way to "move" the focus in preprosessing, or at least make it less obvious that the focus is on the tail.

I'm having trouble parsing the phrase "quae cum audisset," which I've seen translated as "when [subject] heard" or "and when [subject] heard" in the latin vulgate. For instance, Joshua 11:1, 2 Kings 19:1, and Esther 4:1. Here is Joshua 11:1 for discussion: Quae cum audisset Jabin rex Asor, misit...

I am building a web page for a software company, where I want to inform the visitor that our systems are user friendly, among other things. I would like an icon to go with that text. Do you have any idea what that icon would look like? My first thought was a checkmark or a smiley, but they both f...

Is it 0 ℉ or is it 0 K (Kelvin)? From an arithmetic standpoint, it seems like it should be 0 ℉, but that seems inconsistent because the result represents a delta (0 Δ℉ perhaps) which is conceptually completely different. Doing math with units like ℉/s completely breaks down. From a natural scienc...

This publicity slide from NASA in 1972 (?), explaining how wonderfully useful and flexible the Space Shuttle would be, has an intriguing image in the lower right.

I’d like confirmation that $$ \frac{\cos⁡(b \sqrt{a^2+x^2})}{(a^2+x^2)^{3/2}} $$ has the Fourier cosine transform $$ \frac{\pi}{2 a} \, \exp(-ay) \qquad \text{if $y>a$,} $$ as found in Tables of Integral Transforms by Erdelyi et al. equation (35) in Sect. 1.7. I am puzzled that it is independent ...

Scaling a dataset for Random Forest modelling is not necessary. However, if we have already done the scaling and normalization to the dataset, will it impact our Random Forest modelling?

Why does every single band-limited signal in frequency have an infinite time domain and vice versa (As it's a symmetric relation, inf in one is finite in the other). I understand how a digital signal with an infinite slope needs infinite amount of sine waves to approximate or achieve, hence it be...

Let there be a set $S$ of natural numbers from zero to $n$ so that $S = \{s \mid s \le n\}, n \in \mathbb{N}, S \subset \mathbb{N}$. With each turn we pick a random number from the set. If we get one specific number (let's say $0$), the experiment is complete. If we get any other number, we go on...

Currently passengers arriving to Germany from high risk areas have to self-isolate for 10 days (source). 

However, there is a way to shorten that: The quarantine period may be ended on the basis of a negative test carried out no earlier than five days after entry. This seems logistically iffy,...

I'm asked to prove that every totally disconnected topological space satisfies $T_1$ seperation axiom. my proof is this: fix $x\in X$. now, for each $y\in X\setminus\{x\} $ we know that $\left\{ x,y\right\}$ is not connected, therefore there are non-empty disjoint open sets in $X$, say $U,V_{y}$ ...

I've been trying to figure out the differences between 一部, 一部分, and 部分 using GOO's thesaurus. It indicates that 部分 is used for one of several parts, while 一部 and 一部分 are for parts of a whole.

I am unable to understand why the alpha carbon to the carbonyl group is of lower chemical shift compared to the beta carbon based on the effects of electronegativity and hybridisation. Since if electronegativity was a major factor, it would not explain why the beta carbon, which is further from ...

I just installed PMD and its pretty janky from my experience, for example I have two classes and it shows the "same name" error for one class but completely ignores it for the other class.... has anyone experienced this with PMD or do you recommend another tool for code analysis?

Correct me if I'm wrong, but when two or more particles become bonded together, the particle they make together can have its own wavefunction that behaves just like any other. This happens when you go from quarks to baryons, baryons to nuclei, nuclei to atoms, and atoms to molecules. We've gotten...

Can the Federal government of the United States force all U.S. states to pass a mandatory vaccination mandate? Or do the states have the ability to decide whatever they want to do regardless of what the Federal government wants them to do?

In the process of solving this question Integral involving product of arctangent and Gaussian, I've come across the integral: $$ \int_0^b \frac{e^{-s^2}}{a^2 + s^2} d s . $$ This integral appears simple enough that I would expect something to be known about it. Does a closed-form solution exist i...

This is more of a philosophical question. I was looking for ways to increase the font size within math mode locally (eg. in only one equation/align environment) but the solutions I come across often just revert to text mode. I was wondering is there some structural reason in the TeX system that w...

Does Satan tell the truth in Genesis 3:5 For God knows that when you eat from it your eyes will be opened, and you will be like God, knowing good and evil. But Jesus says he lies in John 8:44: You belong to your father, the devil, and you want to carry out your father’s desires. He was a murde...

So Wikipedia says this, which makes sense: But Wolfram computed this: Is this a bug or am I just extremely tired?

I do not have a background with relativity, so expect some faux pas in this question. Let's say I have a system of three balls moving through space. The three balls have a known total mass and a center of gravity with a known velocity, so we can calculate the the system's linear momentum. Now, le...

I have a new frame pump and I want to take it apart. All the way - down to the metal tubes. This is the top of the air chamber and I don't know how to proceed. There is no trim piece covering this and the top of the tube isn't threaded. How is this opened? It should be simple as the leather valve...

The book was about kids who were separated into houses and had to compete in some sort of survivalist game. I think there were four houses; one I remember lasted on eating lots of bread, so they were never in shape. I think the houses were named after Greek mythology. I read it about 5-8 years ag...

In the following sentence from Fabulae Faciles, I cannot figure out what affecta is modifying: Vix vestem induerat Glauce, cum dolorem gravem per omnia membra sensit, et paulo post crudeli cruciatu affecta e vita excessit. Affecta appears to be feminine. I would have expected it to be modifying...

This question was asked in my book: To my knowledge, side chain oxidation with KMnO4 occurs only when a benzylic hydrogen is present. However this doesn't contain a benzylic hydrogen and hence according to me it wouldn't give any reaction. However the answer in my book states that Phenylacetylen...

In short, I want to start a small internet shop (think like Etsy) that sells an idea I have for a handmade item.

Recently, I have noticed a trend here of people fighting to deny self-identifying Christians who deny parts of the Nicene creed the label Christian. I am of course talking about LDS and I guess the part that is denied is consubstantiality(??). Anyway, this question is not about whether or not LDS...

When measuring the rotation velocity of a galaxy, most of the times we can only directly measure radial velocity, by looking at the redshift.

I have a toy car and a battery. The barrery has a screen that shows how much energy it has left. Since kinetic energy is proportional to velocity squared, I need 1J of energy to go from 0m/s=>1m/s, but 3J of energy to go from 1m/s =>2m/s. So I can surely use this to tell what absolute reference f...

The word domus is normally a feminine, IVth declension noun and hence the adjectives that modify it are feminine. However, sometimes domus appears to take masculine forms in some cases.

I have an original Commodore PET from 1977, that I have recently electrically restored, but there are some rust spots on the case. It seems that I should at least do something to inhibit further rusting, and maybe even repaint it. If I repaint, I'm guessing it should be automotive paint, but do...

While reading about sundials, I've seen maps depicting isogonic lines (those that connect points with the same magnetic declination values). Pray tell, what's happening in Antarctica? Why does it appear to have two South Poles? https://www.youtube.com/watch?v=j7LqqvTmnVM&ab_channel=SteveJBlack

I have a SQL resultset exported as JSON, in the form of 1:1 mappings in an array. e.g. [ { "subject": "Accounting", "level": "A Level" }, { "subject": "Accounting", "level": "IB" }, { "subject": "Accounting", "level": "University" }, { "subject": "Accounting

This story from 2016 claims that all the world's energy needs could be supplied by covering 1% of the Sahara in solar PV panels. Was (is?) this true, and if not, how would you go about approximating the size of solar PV array needed to supply the world's energy in 2021? According to the IAEA worl...

What steps could people take to avoid children who are attracted to them magically? The nature of the attraction is that it induces in the nearby (around a km^2) children an ability to sense the attractor's location, and a desire to seek the attractor out. This is the only effect. It cannot be bl...

I'm trying to scale something but I want a corner of it to stay still like I want to scale it from a single point/vertex. Here is an image since I can't explain it well.

I'm sending a board for assembly with a through-hole DIP-8 package with a standard horizontal lead spacing of 7.62mm. However, at their ends the pins are wide with a pin spacing of ~8.47mm. Should I modify my footprint to accommodate this wider width or leave the footprint at its default width of...

I just bought a house and I find this stuff in the loft. I'm worried it is asbestos... Is it?

Two months ago I was hired as a project and team manager in a multinational consultancy company. I have about 8 years of work experience, but only 6 months as a project manager (I worked before in marketing, HR and IT fields). I will try to explain my situation.

PhD days are important in ones life. They influence the research career as well as the academic career of a person to a great extent. In many cases it influences the personal life of a person to a large degree. The quality of a PhD, in general, is assessed or understood by the thesis submitted by...

msvc compiles the following code(with /permissive- compiler switch), clang and gcc do not: template<auto val> struct S{ static constexpr auto val = val; }; int main() { return S<4>::val; } I presume that this is just a msvc bug, but I am curious if maybe standard is ambiguous here.

Suppose a paper is organized with a thesis statement found in the introduction paragraph. Then, each body paragraph contains examples and details that support the thesis statement. The first sentence in each of those body paragraphs though acts as a "mini thesis statement". Example: Cats make gre...

I have recently came across an assignment where I have to do optimal staging of rockets using Lagrange multipliers. I am suppose to optimize the mass of each stage of a well-known rocket(I chose Saturn v), by using their known values of their final speed, payload mass, specific impulses of each s...

I have an external disk which has received some power cuts due to power failures in the office and not having power backup. The disk for now works correctly but I have noticed that there are some files with 0 bytes and other files which have been "lost". Reviewing the hidden files of the system I...

When using a variable in value of switch statement, I get an error: Error: Field must be an enum reference Apex code: static final String VALUE_ORANGES = 'Oranges'; String expr = 'Oranges'; switch on expr { when VALUE_ORANGES { System.debug('Oranges are $0.59 a pound.'); } w...

I guess this may be a naive question but I can't get my head around so I felt like asking... I was searching for some solution to a problem, when I found this very interesting post about why is using [while|for] loops in bash considered bad practice. There is a very good explanation in the post (...

I have read that wealthier states tend to vote Democratic while poorer states tend to vote Republican. There is data that backs this up. What is the correlation between statewide median incomes and 2 party Democratic vote percentages?

One of the queries in my application is timing out. With the SQL Server profiler I was able to get the exact faulty SQL code. It's an sp_executesql dynamic statement that runs in > 2 minutes in SSMS on the server. In contrast, running the same SQL ad hoc - outside of sp_executesql but still with ...

In Fabulae Faciles, section 82, I do not understand the expression "aliae alias in partes". Is this some kind of idiom? The phrase is: Postquam tamen pauca mīlia passuum ā lītore Trōiae prōgressī sunt, tanta tempestās subitō coörta est ut nūlla nāvium cursum tenēre posset, sed aliae alias in par...

FILE-A has 100,000 lines. FILE-B is 50 search terms. I'm looking to complete the search of FILE-A (CSV or TXT) with the various terms from FILE-B (CSV or TXT) .... AND (here is the kicker) Save the results in individual TXT files based off the search terms in FILE-B. Example: FILE-A 123 45678 ...

I'm working on a class AB amplifier that is used to either source or sink current. The reason for using MOSFETs is space constaints and that high power BJTs are only available in large leaded packages. I tried to look around for some biasing circuits to reduce crossover distortion, but most desig...

This is truly crazy. I received a SPAM email in which there is a URL crafted from apparent Unicode characters that surprisingly exist for italic/bold letters, which when I reported it to Google's spam collector using Thunderbird's Report Spam Email feature it had already been converted to ASCII l...

Conferences are a great platform to exchange ideas and to learn about different research areas. Also, more importantly, conferences expedite the process of publishing as journals may take months/years. However, my question is - "why was is it mandatory to attend a conference in person in order to...
