Problem I've purchased some broccoli, and it is pockmarked by short, black streaks: I've been informed by my father that it indicates rot, although the broccoli otherwise appears firm. A comment on Reddit appears to offer a more reliable explanation: Those black "spots" are evidence of Xanthomo...

I am getting a house built in Australia where I have opted for metal framing (to mitigate termite attacks). I have no experience in metal framing. As much as I can think ahead, I am getting the builder to add timber dwangs where I may want to fasten things in the future. But there will be unfor...

When a airliner takes off, it looks like after rotation and lift-off, the plane flies up in the air parallel to the length of its fuselage. Assuming lift from the wings is the major force in taking off, that should not necessarily be the case. (E.g. during landing the fuselage is typical at an an...

I suppose the alternative is that fictional knowledge is empirical. Currently I’m thinking fictional knowledge is an important issue regarding the debate surrounding a priori vs a posteriori knowledge. I'm looking for clarification on the interrelation of these terms. Please provide some analysis...

I‘ve read the following sentence: Я не кровный родственник этой семье, но, наверное, именно поэтому я могу смотреть на всё со стороны. Here, семья stands in the dative, instead of the genitive. Is this usage of the dative case dated/archaic or regular modern usage? Generalising from this, can I...

According to the first chapter of the HoTT book, dependent functions beget products: $$ (x : A) \rightarrow B\,x \equiv: \prod_{x : A} B\,x $$ of which $A \times B$ is a special form ($A \times B \cong \prod_{b : \mathrm{Bool}} T\,b, T\,\mathrm{false} = A, T\,\mathrm{true} = B$), and likewise, de...

I happen to recall that CHACHA20 ciphers are not compliant with both NIST guidelines and FIPS/HIPAA standards. As used to be stated by htbridge.com SSL tests years ago.

I've been playing the game War Thunder recently. It is common knowledge in the game that angling a tank's armor, even slightly, will significantly increase the effectiveness of protection against enemy fire. This led me to wonder: was the concept of angling tank armor consciously employed or reco...

From this picture from Episode 2 Season 1 of Mad Men, I have circled two cigarettes in red and three smoke alarms in black on the ceiling. I am assuming they are smoke alarms. If they are, why are they not triggered by smoke coming from cigarettes in the office?

Let $A$ be a commutative (unital) ring. Does there exist a faithful Artinian $A$-module $M$? I must admit, I haven't made much progress on this question, so I have very little work to show. Obviously, dropping the faithfulness requirement, one can take $M = A/\mathfrak m$ for some maximal ideal $...

I recently encountered the surprising claim that letting your cat go outdoors will shorten its lifespan by 10 years. I am wondering about the difference in lifespan between an indoor-only cat, and a cat that is cared for with a bed and food indoors but is allowed to go outside, henceforth called an

In the 1985 version of Teen Wolf Scott's close friend is named "Boof" (though IMDB does refer to her as "Lisa 'Boof' Marconi"). Is the origin of that nickname given anywhere in the movie or in related media (a novelization)?

We hear St Paul exhorting in 1 Timothy 3:2 (KJV): The bishop then must be blameless, the husband of one wife, vigilant, sober, of good behavior, given to hospitality, apt at teaching; Some versions use the phrase ' should be faithful to his wife' in lieu of ' husband of one wife' . A layman gen...

Towards the end of Scene 1 Galilei says: Ich gebe es zu, es macht mir Spaß, ihr meine Herren Venezianer, in eurem berühmten Arsenal, den Werften und Artilleriezeughäusern meinen Mann zu stellen. He seems to be saying that he enjoys playing his part in Venetian life, but I may be misreading this...

I can use the foreach() function with a string, like so: :call foreach([37,73], 'echo v:val') 37 73 or with a Funcref: function Foobar(key,val) echo a:val endfunction :call foreach([37,73], function('Foobar')) 37 73 but it doesn't work with a lambda expression: :call foreach([37,73], {key,val ->

The advantages (for me) would be: Common availability of 48t-34t chainrings, which are more suitable for my riding speeds. (I seldom, if ever, use the 52t/11-12t or 50t/12-13t gear combinations.) Easy availability of top-tube bolts. Those provide a non-wobbly, guaranteed-scratch-free set-up for...

Let $F$ be a field and $f(x)\in F[x]$ be a monic polynomial. Denote by $a_1,\cdots,a_n$ the roots of $f(x)$ over $\bar F$ the algebraic closure of $F$. Then $f(x)=\prod_{i=1}^n(x-a_i)$ splits completely in $\bar F[x]$. [1] Can we directly say that $F(a_1,\cdots,a_n)$ is the splitting field of $f(...

I have a consumer-grade Bluetooth LE tempeture sensor like this: I noticed that, when moving this device from outside (+3°C) to inside (+20°C), it takes a huge amount of time to get to the right temperature (+20°C), probably 1 hour or 2 hours. After 10 minutes it is still at value +10°C. Questio...

I wonder, in everyday life, when I feel really cold outside and I want to rush indoors for warmth, how these ascetics deal with it.

I was looking at the Greek of 1 John 3:12 - and I noticed how different versions translate the passage differently. Some say that Cain murdered his brother, while others state that he killed / slew his brother. While the Greek permits all of these - choosing to call Cain a “murderer” instead of a...

Consider a quantum particle in a box (everything one dimensional, for simplicity). The box is isolated from everything else. We could not measure simultaneously the particle's position and momentum, because they are complementary variables, $$[x,p] = i\hbar$$. Since the system particle+box is iso...

I've came across several stories of a type of "role reversal" where Europeans wind up enslaved by either Africans or Native Americans.

I am learning the exact diagonalization of quantum many-body systems. Let's take a spin model as an example. Setting $N = 4$, we have 16 states, namely $|\psi\rangle = |0000\rangle, |0001\rangle, \dots, |1111\rangle$. I can express the Hamiltonian $H$ in the $|\psi\rangle$ representation and diag...

As a result of doing lots of flying I've received 4 vouchers from Alaska that in theory entitle me to found business class upgrades in the next year.

Why is it that our relation to death makes us authentic? We cannot much, it seems, overcome death that way. Is it some conscious idea or response to our own death that makes us authentic, and if so then how can that be, how can something postponed while we are acting make us act real or fake? Th...

The question is If a (commutative) ring (with unity) has a unique minimal prime ideal, is the nilradical prime? I just thought of this as the converse is true (and it follows immediately from the fact that the nilradical is the intersection of all prime ideals). My attempt: Let $\mathfrak p$ be...

Similarly to CP/M, the kernel of MS-DOS up to version 6.22 was split into two files: the (DOS-)BIOS, carrying the name IO.SYS (or IBMBIO.COM), and the BDOS, named MSDOS.SYS (or IBMDOS.COM). With MS-DOS 7.0, which is the version incorporated into Windows 95, the BIOS and BDOS were combined into a...

I'm having a hard time understanding how to choose values for the resistor and capacitor in an RC low-pass or high-pass filter. I think I understand correctly that... The "worst-case" input impedance is roughly equal to R, so it's safe to use R as the input impedance in building the circuit. The "

A branch fell on my roof and it landed on my gutter. Because of this, the water is now pooling at one end instead of flowing to the drain. It seems that the branch bent the end of the gutter, so it's not tight against the fascia board anymore. How do I fix this? Can I just screw the end of the...
