Nice! I see that Inkscape has support for 'G-code' (which I am just learning about ...) On a related topic, I'm looking into XY plotters to draw designs on paper - does anyone know the easiest or cheapest way to do that? Buil

Isomorphism of a pair of graphs usually refers to isomorphism of their unlabelled equivalents. Yes the concrete expression of the isomorphism would be as a mapping between the labels. Given that the paper linked to is by Brendan McKay et al

Not sure how? As a thought experiment, say I created two languages completely from scratch : symbols, words, sentence order, etc. One of these languages, I've given meaning to the words, the other is random. However I create massive co

Oh I agree that google is the ultimate open book! Perhaps certain subjects are better suited to having broader questions. I still think it would be _possible_ to create CS questions that would not be helped by having access to a search engi

There is such a thing as an 'open book exam' where you literally have access to the textbook in the exam. The purpose of such exams is not to test your memorization of the subject, but how well you understand it. The questions are

It's quite short. I can't find a link to a quote online, a transcript is: "Last month, the notorious paedophile Sidney Cook was blasted into space, to spend the rest of his life aboard a one-man prison vessel, posing no furth

Agreed, I am sure that the drive for axiomisation of geometry drove a lot of this interest. All I really mean is that actually using these tools for an artistic, constructive purpose gives me a feel for why these problems might of been of i

Exactly this. There are many patterns that can be constructed by drawing a regular array of circles, then connecting various intersection points with lines, then erasing the original circles. As it happens, I sometimes find that the same dr

A great example of such a range of bounds is the problem that Graham's number was an upper bound for : https://en.wikipedia.org/wiki/Graham%27s_number "Thus, the best known bounds for N* are 13 ≤ N* ≤ N'

What's interesting to me is how many of the ancient problems involve using compass and straightedge. Recently I have been trying to draw Islamic geometric patterns (or other tilings, like quasitilings) using compass and ruler, and it c

I'm curious - what is the story of homeopathy in the United States? I know it is oddly popular in Germany.

Agreed, it can be very difficult for anyone to make useful decisions outside of just trusting the existing consensus. I mean there is no real way for me to know if a vaccine is safe. I assume it is, and prefer to gamble on it not harming me

I also find that if you put the solution in your hands, at the right concentration, and then form an oval with your thumbs and forefingers, you can blow very large bubbles. You have to start slowly, until a large curve forms, then expand th

Yes, a common way to design new structures is to 'thread' the sequence onto existing folds. Rarely, there have been attempts to engineer entirely new folds, although it's not clear how necessary that is.

Well ideally digitisation would not be destructive, I suppose. With any preservation or analysis of historical artefacts there is some risk/reward calculation. Like some books are so delicate that there is an approach to scan them whil

Well concern for one's safety in the face of dangers that are real and immediate is the process of a rational mind.

Nice. I suppose it also depends on how rare the item being scanned is. For a recent printed work, with multiple copies it's less important, while scanning a fragment from a Genizah or a notebook is much more careful process.

That's pretty insane. Oddly enough - the process in a library for digitising a copy of a book can be fairly destructive, as far as I understood from those doing it (at CUDL). The spine is chopped off, to make it easier to put it into a

Totally agree with your point, but just because I was curious... Isaac Newton lived from 1642 – 1726 so technically: * 1642-1649 : Charles I (until he got the chop) * 1649-1660 : Interregnum, Cromwell and Son * 1660-1685 : Charles II (Resto

All art is a mixture of craft and marketing. There's just a lot more marketing to modern art than classical art.

Yes and no. Biological systems are similar to mechanical computers in that they are information processing systems. However, they are also self-assembling, self-repairing, wet, massively parallel, etc. Artificial biological systems are in a
