ProcyonicI am currently working as a teaching assistant for several courses in STEM in the US at the college level.

Q: Has the distribution of income and wealth in the USA got much more skewed towards the rich in the last 4 decades?

matt_blackI recently asked this question about a statistic quoted by Kurt Andersen designed to illustrate the current wealth distribution in the USA in his book Evil Geniuses.

Q: in/at one fell swoop(=at one time) What's fell here?

Brandonin/at one fell swoop (=with a single action or movement, all at the same time) What's fell here? I think 'swoop' is a noun and if it should be modified, then 'past participle' or adjective should do it. Let's look at the below. 'fell' is past of fall and infinitive of 'fell'. No adjective element...

Q: Why didn't early color TV sets accept RGB input?

SchezukEarly PCs generated RF signal, and later Composite video or S-video, to use a TV set as monitor. Why didn't color TVs of those days expose a analog RGB interface for direct connection from VCR/PC or any other local device? There must be some stage in the TV where chroma-luminance signal has alrea...

Q: Non spectroscopy related uses of fourier/laplace transform in chemistry?

Hugo Moeller NielsenThis is my first post here, so please correct any mistakes related to my question (if any).

Jonathan AllanPreamble There was a unit test in our codebase which was shuffling a string of [A-Z]+[A-Z] and then using the first twenty characters of that shuffled string.

Q: How do Christians who reject pre-fall death reconcile their views with the Cretaceous–Paleogene extinction event (66 million years ago)?

Spirit Realm InvestigatorMany Christians believe that creation was cursed because of Adam & Eve's fall into sin, and that death entered creation because of the fall but not before. In other words, the idea of pre-fall death is rejected. I personally believe that this is a very reasonable position to hold from a Scriptura...

Q: Why isn't this estimator unbiased?

PeacefulSuppose we have a IID sample $X_1, X_2, \cdots, X_n$ with each $X_i$ distributed as $\mathcal{N}(\mu, \sigma^2)$. Now suppose we construct (a rather peculiar) estimator for the mean $\mu$: we only choose values from the sample that are greater than a pre-decided value, say $1$, and then take the ...

Q: Bitwise operations in Bash not working as expected

PourkoI ran into a strange problem. To demonstrate, let's take the largest unsigned number on my machine (printf "%X \n" -1 gives me FFFFFFFFFFFFFFFF – i.e., 16 Fs) and try to shift some bits.  First, shift to the left: printf "%X \n" $(( 0xFFFFFFFFFFFFFFFF<<4 )) FFFFFFFFFFFFFFF0 printf "%X \n" $(( 0x...

Q: Plausibility of an atmosphere on the furthermost planet of a solar system

Could a planet, say 44 AU away from the Sun, have a volcanic atmosph...

Q: Why does the VICE "load" command skip the first two bytes?

Bart FriederichsI am studying assembly of the C64, and of course using VICE to do so. VICE has the load command to load data straight into the C64 RAM. I reckoned I could use that to put machine code into RAM and run it from there. The weird thing now is that the load command seems to skip the first two bytes wh...

user42444"Does not nature itself teach you that if a man wears his hair long it is a disgrace to him, whereas if a woman has long hair it is her glory, because long hair has been given her for a covering?" (1 Corinthians 11:14-15)

Q: Why does 「もう待てないよ!」 mean "I can't wait any longer"?

古手梨花I've just learnt that the expression 「もう待てないよ!」 has similar meaning in English as "I can't wait any longer", but how to interpret 「待てない」 from a grammar point? Shouldn't the "te-form" of 「待つ」 be 「待って」like in 「待っててね!」? And why 「待ってない」 doesn't mean something like "I'm not waiting (right now)", since...
