Historically, at least to my eyes, this seems to derive from how mathematics has been cited by mathematicians. Before a thing is called 'Levenshtein Distance' it will be used by someone saying 'calculating distance between th

The kinetic energies involved can be huge . In the same way that an object won't explode when hit by a subsonic 9mm round with ~0.5kJ of muzzle energy ('just' causing a leak and decreasing amount of blood pressure) it will w

Space is big. It's extremely unlikely to get close to any object while randomly passing through its orbit. Unfortunately, space becomes a lot smaller once you want to park yourself in a similar orbit to another object. Don't get

Just an FYI in case people don't know, tea often has plenty of caffeine in it, and many tisanes/blends/etc will have sugar in them as well. So if you're trying to avoid caffeine or sugar you need to be careful when choos

Thanks, that's a really great example. It definitely feels non trivial to come up with an example.

To confirm I understand (and I think this is where I was at originally): If a graph contains K_5 then it requires at least 5 colours to colour, but if a graph does not contain K_5 then it might still require 5 colours. The example given by

Is it true to say that a graph can be coloured by k colours if and only if the largest fully connected subgraph has k or fewer members? For example, is saying a planar graph can always be coloured by 4 colours the same as saying a plana

Fair enough. I'm not sure what that means though. If I printed off the form from the website would that count as me writing the letter to be mailed? In any case, in the stuff quoted up top, I don't read this concept that it must b

Reading the above comment, where does it say it has to be personally mailed? > Your notice must be mailed to us at P.O. Box 15298, Wilmington, DE 19850-5298. That sounds like it has to be mailed, but who does the mailing doesn't m

That's why they tend to talk about Sudden Unexpected Infant Death these days. My understanding is that the primary concern is the ability of the child to breathe normally. Anything which restricts that ability can be life threatening.

Things I haven't yet been able to determine, noting that I haven't dived into the paper yet, are: - What temperature range does this happen at? - Is the resistance measured edge-to-edge across the sandwich, or between the layers?

And for that reason, if I was using speech-to-code, I would probably use the alternative forms of 'round bracket', 'square bracket', and 'curly bracket' when I need to specify the type.

Seems like the crucial step here was being able to develop a systematic way to address every possible type of 'repulsive force' in a given dimension, which then allowed them to show that the given solution (for example E8 in dimen

Ok, I think it was fairly similar then. Assignments were graded automatically (based on passing test suites essentially) but individual labs hadn't been set up the same way. With style I always felt it was easy to say if it was bad or

The point of the article is that we don't consider a unit in a number system to be prime, and in the integers/rationals/reals 1 is a unit. Why we don't consider units to be prime is more than just it "makes more m

When did you TA? I was TA for 1911 (I think?) around 2008-2009 and don't recall any automated grading system. It would have been so nice too, as labs would end up with students trying (struggling!) to complete the lab, get the lab grad

In the video they show him moving a large shed over a dirt path. He used a pivot sitting on top of wooden shoring boards, I can imagine the process for any weight would be similar.

This argument falls flat because it doesn't show a requirement that the first proceeds the second, and additionally it assumes that "the end justifies the means". It may be true that our current scientific culture arose from

I agree with you, but was trying to illustrate an example from the class of 'one byte is eight bits' style assumptions. Hopefully I made it clear that 'one character -> one byte -> eight bits' is an assumption that
