Q: What are good ways to spray paint a QR code on a footpath?

thevikasThe QR would be of a URL. The QR should be big enough like 4 A4 size papers. I though of cutting out the white boxes from a printed paper and spray on it but what about white dot islands. The precision needs to be good enough for a cell phone camera to detect it on the floor from standing distance.

The group is then on the receiving side of ...

Q: Are the only single element normal subgroups precisely the elements that make up the center of a group?

Leo BloomSo, a single element normal subgroup $n$ of group $G$ would be defined as $ \forall g \in G: gng^{-1} = n$. All elements of an abelian group would qualify, and so would more generally the elements of the center of a group, since $gng^{-1} = gg^{-1}n = n$ for $n\in \text{Z}(G)$. Thus, to prove th...

Syed Hasnain AhmedCan we arrange a practical in such a way that the dark and bright bands in diffraction grating be allowed to pass through the same slit to get the original light (i.e the incident light before diffraction), just like we reverse the arrows in reflection and refraction

Q: Why is the divergence of this series apparently not predicted by the Monotonic Sequence Theorem?

sirmax224As far as I understand, the Monotonic Sequence Theorem states that if a sequence is monotonic and the individual terms are bounded, then the sequence is convergent. My book states that $\lim \limits_{t \to \infty}\sum_{n=1}^t b^{\ln n}$ is convergent only for b $\lt$ $\frac{1}{e}$. However, is ...

Mr. MendelliI'm working on a custom settings script for Windows that will automate specific settings I want on a new Windows machine or installation. I grant access to some folders using cacls in my script, but I am prompted with the Y/N on each item. I would like to bypass this by automatically saying "yes...

Q: Why is Bézout's identity considered an identity?

John_NashIn most cases, identities seem to take values and give outputs that are irrelevant to the input data. example: $(a + b)^2 = a^2 + 2ab + b^2$ $[\cos(x)]^2 + [\sin(x)]^2 = 1$ Yet Bézout's identity only seems to assert the existence of something, not a relation of the above kind. Am I miss...

Q: Do monad transformers, generally speaking, arise out of adjunctions?

Q: In native German words, is Q always followed by U, as in English?

JamesFaixIn English, native words with a Q always have a U immediately after it. (There are some borrowed words like "faqir" from Arabic that do not follow this pattern.) I am starting to learn German. Every word with a Q that I have seen so far follows this convention, but the sources I have been using ...

Q: Is it bad to describe a character long after their introduction?

A. KvåleI have a tendency to forget to describe character's appearance. But I always describe them, though often a little while after their introduction. So, how long after someone's introduction is "acceptable" to describe them? In my case, (the case that prompted me to ask this question), the character...

Q: Golf the smallest circle!

BarrankaThe problem: Given a non-empty set of points in the cartesian plane, find the smallest circle that encloses them all (Wikipedia link).

Q: Why does this function call behave sensibly after calling it through a typecasted function pointer?

DivanoI have the following code. There is a function that takes two int32. Then I take a pointer to it and cast it to a function that takes three int8 and call it. I expected a runtime error but program works fine. Why this even possible? main.cpp: #include <iostream> using namespace std; void f(in...

Q: Why Is Abelian Gauge Theory So Special?

The Last Knight of Silk RoadI have a perhaps stupid question about Maxwell equations. Let $G$ be a generic Lie group. We consider a $G$-gauge theory. Let $A$ be the associated connection $1$-form, and $F=dA+A\wedge A$ be the corresponding curvature tensor. The Yang-Mills equations can be written as $$D\star F=\star J \ta...

Q: Does a centaur PC also count as being mounted?

Code MonkeyOne of our characters created a centaur Eagle totem barbarian (level 3) - which I thought was a good idea. But to duck and weave in tight spaces, she'd need high AC, so she came up with a character wielding a lance in one hand and a shield in another. Whilst wearing scale-mail, she'd have a total...

Q: How do accents of a whole town drift?

zoobyI've heard it said that accents of towns drift over time. I find this hard to comprehend as how could an accent of a whole town change? I think it is established that we mainly pick up our accent from our peers at school. But this is also odd, since if we are separated by age, peers in an age gr...
