I want to export many PNG pictures using Mathematica. However, it takes too much time. To make matters worse, sometimes it suddenly aborts. With any pictures, I have same problem. For example, I Import about 1000 pictures of 2000x2000 pixels as "imagelist" and then each of them are divided into 2...

When I was taught undergraduate set theory I was told that the idea for club sets is that they are "of full measure" and the non-stationary sets are "of null measure". (There were more than two people saying that it seems, giving me an impression that there might be a particular reason behind it,...

the gnfs is the most efficient algorithm for factoring numbers formed of equal composites. But it’s sequential parts means (If I’m not wrong), that it requires at least 10 minutes on current hardware to factor semi‑primes formed of composites of equal length (in the case of 382 bits semi‑primes)....

In Windows each drive has a letter and file paths start with a drive letter. so my home directory is inside C:\Users.

This is a question about how Mathematica works, rather than how to solve a specific instance of an issue, so apologies in advance if this isn't admissible for this StackExchange. I've noticed some weird behaviour about how quickly code runs, and I'd like to understand why one case is so much fast...

I'm working on a hand and I tried connecting the thumb using Merge at Center [M], but I came across this mesh error and I'm unsure how to resolve this. I used Merge by distance but it's not working, I redid the whole hand however the same issue reoccured. How can this be solved.

personally it's easier for me to study words/phrases to understand the roots, but I have an interesting word that I can't figure out why it was derived from 角色 Corner and Color... how did that become to mean someone's Role?

I know how long it takes to charge a capacitor given constant voltage (that's the first thing everyone learns about capacitors). In my search to answer this question for constant power, I discovered the answer instead for constant current here. My first thought was \$Q=CV\$ and \$I=C\frac{dv}{dt}...

Finding offset of a filesystem that resides directly on a partition is easy: check the partition start sector, multiply by sector size, done. What if the filesystem lives inside LVM?

Here's the definition of a sequence as laid out in the text: Let $m$ be an integer. A sequence $(a_n)_{n=m}^\infty$ of rational numbers is any function from the set $\{n \in \mathbf{Z} : n \geq m\}$ to $\mathbf{Q}$. I can make sense out of this definition, but I was under the impression that a ...

I understand that fictionalism can be attributed to a majority of disciplines, the ones I am familiar with are modal fictionalism, mathematical fictionalism and moral fictionalism, so I was thinking can we apply the philosophical ideologies of fictionalism to philosophy itself if so then what wou...

Another question had raised this issue when fairies were part of Unearthed Arcana and indicated that they couldn't because the flight was magical. However, I noticed that on DND beyond that the flight is because of the fairy's wings, a non-magical source, and now I don't know what to believe. The...

Birkhoff's Fundamental Theorem of Finite Distributive Lattices says that there is a bijection $$ \{ \textrm{finite posets}\} \to \{ \textrm{finite distributive lattices}\} $$ $$ P \mapsto J(P), $$ where $J(P)$ is the set of order ideals of $P$, ordered by containment. The inverse of this bijectio...

The Lindelöf hypothesis says that if we have: $$\zeta(\sigma+iT)=\mathcal O(T^a)$$ Then if one considers $\sigma=1/2$ then $\inf a=0$. Further, from convexity and the functional equation this implies that $a=0$ for $\sigma\geq1/2$ and $a=1/2-\sigma$ for $\sigma<1/2$. I am interested whether there...

The first episode of Star Trek/TOS that used a shuttlecraft was The Galileo Seven, which included the full interior and exterior of the shuttle.

According to the fairy description, fairies are infused with the magic of the feywild: Infused with the magic of the Feywild, most fairies look like Small elves with insectile wings… Does this mean that if a fairy enters an antimagic field, it just dies?

Dr. Becky (Smethurst) just posted a new YouTube video mentioning, as I have heard many times, that it might not be possible for life to form on planets around Red Dwarf (M) stars because they would have to be orbiting close in, but that that would put them in range of constant blasts from the sta...

We read in Hebrews 10:1-4: The law is only a shadow of the good things that are coming—not the realities themselves. For this reason it can never, by the same sacrifices repeated endlessly year after year, make perfect those who draw near to worship. Otherwise, would they not have stopped being...

I suggest that zero is a cognitive crutch, a way for humans to grasp the concept of absence, but not an objective existence in itself. By using zero, we're essentially creating a placeholder for something that's inherently difficult to comprehend – the absence of quantity or being. This would res...

So in virtually all English-language calculus classes I have seen, we define integration as the "accumulation of change". And that makes sense to me intuitively, but when I think about it, I feel like accumulation of value makes more sense. Because if we take the change in a function $f:\mathbb{R...

For example: we observe an ant carrying food back to its nest. We may speak like the ant has a goal of increasing the amount of food in the nest. We observe a student proofreading an essay.

There's something I can't quite wrap my head around, and I am not satisfied with my professor's "that's just defined that way" answer. So suppose we have: $$f_1(x) = x - 5$$ $$f_2(x) = \frac{1}{x - 5}$$ $$f_3(x) = 1$$ By simple algebra, we can see that $f4(x) = f_1(x) \cdot f_2(x) = f_3(x)$ What ...
