There actually was a very loud alarm. From memory it was about 9:30am this morning (technically yesterday). One can hear the alarms on the base from Kaiserslautern fairly easily, though normally they are just drills.

If I were a business, the answer is no, the regulations are very strict. But I am not a business, I'm a hobbyist. I derive no income from my channel. By my estimation you would need at least five employees in Germany to run an online b

This is not workable in Germany. There are huge fines for running YouTube businesses without putting business details at every location your video appears on the internet. German State administrators have sent out such fines simply because

Everybody learns that at school, French or not (I certainly did in Australia). The set theory referred to here is very abstract.

But how did Bourbaki influence elementary/middle school mathematics? Bourbaki mathematics is basically at the level of graduate school. Except in countries where a graduate degree is required to teach mathematics, I can't imagine

That's interesting. I'd seen Arnold's work on teaching mathematics, and I'm very much aware of the dry formalism in Bourbaki books. However, I was not aware of the Arnold-Serre debate. But the thing that really caught my

I think R0 for the flu is usually take to be in the range 1.4-1.6 and for the common cold, 2-3. It's significant that it is quite a bit over 1, as it wouldn't spread so effectively if not. It's an exponential factor, so small

You need encrypt(1) + encrypt(2). You would not be sent instructions to add 2. No information about what you are doing is sent, except the operations + and x. As the comments in the article state, it's actually all done with operations

I'm aware that mainstream archaeologist don't find evidence of an exodus of "Jewish" people from Egypt via the Sinai into Caanan. I personally don't buy their arguments (no dung piles in the desert, no artifacts fou

I don't completely follow your second paragraph. Are the Philistines now believed to have been Hebrew? That's a development I wasn't aware of. I'm also not clear how the use of Hyksos-style chariots by Ramesses II's

Right, but one presumes that Josephus (a later Jewish historian) identified the Hyksos with the Hebrews? And he used the priest Manetho's works as source material for that claim? So I'm curious if that is what the authors of this

The authors don't say which race the Hyksos have traditionally been associated with. Do they mean the Hebrews? It is interesting that the strontium isotope analysis suggests they did not come from a single homeland, but were from a var

Sure. It's just nice to know what the limitations are in that regard. Some demos for the Atari 8 bit machines for example did use them that way by lowering the resolution sufficiently far and then writing really tight assembly language

What I'm really curious to know is at what effective screen resolution it will have sufficient power to update every pixel on the screen in a single frame (assuming you are using assembly language and true graphics, not a character mod

Harvey-van der Hoeven. And yes it is. But this is an asymptotic cost meaning you have to have absolutely enormous integers before the cost will be lower than the old algorithm. In fact, the crossover is so large it is quite possibly out of

SageMath takes 3s to load for me (sometimes a lot more if my systems administrator has updated it recently, which seems to happen a lot). I therefore use Pari/GP for my personal choice. I like the symbolic nature of Pari/GP over S

There is very likely not a reliable scientific guide to making and keeping friends, because it depends very much on the circumstances and the people involved. Some people have many shallow friendships, others just a few deep ones. Some peop

The problem is, unsophisticated models do not predict anything. You apply them in one country and they do ok, and apply them in another and they get it totally and completely wrong. Unless all important factors are accounted for, they are g

Given that it took me a year to learn to drive, I wondered how he managed it. I had realised that given he wanted to buy a Lambo, he obviously loved cars. But eventually I realised it was probably an automatic not a manual transmission. It&

This was an interesting read. The style of presentation is quite unique. The overall tone of the article is in favour of vaccination, but it nevertheless provides many exact quotes of antivaxxers and other conspiracy theorists, usually with

True, but that could be a single cherry-picked example just for the article. It does sound like the typical case might not be too far off that though, which is potentially very good news.

"We are all gonna die" is a statement about the mortality rate, not the case fatality rate. This paper does not deal with the mortality rate.

If I am reading it correctly, that is not what the paper says. It says that it takes into account the individuals who had the disease but were not reported/recorded. Further to that, some individuals are asymptomatic which means that n

It's worth pointing out that this is the CFR for the virus, SARS-CoV-2 (i.e. including asymptomatic individuals). The CFR for the disease, COVID-19, is 3.3% (2.9-3.8%). I'm not sure which it is more common to report, but the 2% es

It's clear the WHO message is trying to present the bad news in the best possible light. The sentences about transmissibility are very obviously constructed extremely carefully. However, I do take away from the report that Governments

Isn't it still a derived work though? (Serious question, not rhetorical.)
