Spoiler: there is a simple argument against the existence of such a lower bound.

Interesting follow-up question: What is the distance between the set of harmonic numbers and the integers? i.e. is there a lower bound on the difference between a given integer and its closest harmonic number? If so, for which integer is th

Even today it is exceedingly rare to find a still-well-conditioned bottle of wine that has the capability to have aged for 117 years or so. Most often sweet wines are capable of this.

FWIW I was also sceptical, but just tried it from my phone network and it seems indeed blocked. Wouldn't be the first case of different ISPs using different block-lists. c.f. bs.to

Measure its volume by dunking it in a jug of water and compare its weight with its expected weight (depending on the density of gold). There is a famous tale of Archimedes doing exactly this when posed with the problem of determining if a c

Do not underestimate the urge to procrastinate (by still doing productive things, like learning Mandarin) while pursuing a PhD. I am not sure if this will be the author's experience too, but pursuing a PhD will often leave you exhauste

You can get gcc to generate the blend instruction in the example given - you just have to 'force' it to use SIMD more aggressively by, for example, using -march=native.

I recon the general cosensus among mathematicians (as that is what counts) is that the ABC conjecture so far has _not_ been proven. Mochizuki (and his school around him) seem to be the majority of people that believe his proof is correct. A

I think giving any more details than his three short posts would delve too far into the specific arguments of the paper to be valuable for a wide enough audience, subtracting those that are going to be looking at the pre-print anyhow.

Unfortunately the presented method only works for the most simple linear recurrence relations. Tangentially: look up the master theorem if you're interested in at least estimating growth rates for recurrence relations that crop up in c

Just because of the impossibility of an exact formula for the roots of a high-degree polynomial that does not rule out the possibility of figuring out, say, the distribution of roots of such polynomials. The question is not about any polyno

This sounds like an organisational nightmare to be honest. You'd be going through the pile of exams multiple times (at least twice) and what do you do if there are multiple mistakes that are common in a single exam question? Also: if y

Regarding you last point: out of interest, what kind of venues were you thinking of? Be this personal blogs of said academics, just dumping it on a preprint server or actual ("formally published") publications?

That is definitely not true - I have an analog wrist watch (and am under 30). Also, there can be benefits to the use of analog clocks: in some circumstances they're quicker to read the time off of. http://www.mcld.co.uk&#x2F

I'd deem it useful, though unusable in practise, as GMail for example does not accept messages that contain multiple From addresses.

To clarify, I guess you mean "Captain in the navy", equivalent to a Colonel in other branches. A captain in the army is O-3.

The difference is that in the Schrödinger case you're effectively 'turning' the solution (in the complex plane) which leads to the uncomfortable question of whether the solution to the heat equation you'd start with is s
