The world is made of two types of particle - fermions and bosons. A difference between them is that fermions can not occupy the same quantum state (the Pauli exclusion principle) while bosons can exist as superpositions. Matter is made of e

I think they mean that the model should have sleep period where they update themselves with what they learnt that day.

We actually use the twitter detections to launch analyses of the seismic data in order to get confirmed results for events that aren’t reported yet [1] but there are some statistics for the twitter detections in the supplementary material o

There is also the Earthquake Network (EQN) app that works on very similar principals to Google’s system - phones monitor their MEMs accelerometers, when they are left charging with their screen off, and when enough neighbouring phones detec

The USGS created a system to do exactly this about 15 years ago. I’m not sure whether they’re still running it but at the EMSC, we've been running a similar system for many years to highlight earthquakes important to the public and imp

Can anyone explain the maths that he did because my calculation give different results. Isn't there only a 1 in 2588 chance of a student 'guessing' 19 'answers' out of 45 where there are 5 options for each answer?

Actually, I can't seem to get the maths to work. Isn't it just the Binomial distribution? Each question has 5 options so the probability of 'success' is 1/5 and so to get 19 questions 'specifically wrong'

This feels harsh because if the tests were similar but with small differences then getting the right wrong answers seems likely to happen anyway. Also, he went the extra step and outright failed the student but I'm not sure why that ex

For all of my major exams in the UK, we were encouraged to study by practising on old papers and my score would have been abysmal if I hadn't. So not being allowed to look at past exams feels strange to me too.

There is a strong connection between the incandescent lightbulbs and the sun because the sun is almost a blackbody emitter too. Studying incandescent lightbulbs allowed researchers to discover the blackbody spectrum and Kirchhoff's law

I agree with this sentiment but in this particular case, with the personality that Putin projects to the world, it seems like appeasement would just encouragement him to try to take more.

I like nim but I've never really gotten used to the slicing syntax. I guess that I'm just too used to python, plus you have to be a bit careful to leave a whitespace when doing backwards indexing so that the operators work correct

You can easily get bash to do that by adding these lines to your .inputrc file. "\e[A": history-search-backward "\e[B": history-search-forward "\e[C": forward-char "\e[D": backward-char

Relative imports used to work much more naturally IMHO in python2 but then they broke it in python3 because Guido wanted scripts and modules to always be separate codebases. So, whereas it used to be easy to have a module that could also be
