The Protagonist is a suave, charismatic young man and his girl, ending up being persecuted by a rigid dystopian future state.  Some details I remember:    Featuring a possibly sympathetic military officer (who is an old family friend/acquaintance) driving a jaguar. which gets hijacked on a highway by hooligans. Being military, it's got an emergency button calling in a gurkha special force unit in helicopters. The hooligans are heading straight for organ transplant vats.  There is a tea ceremony metaphor, illustrating the pathological state of today's job market - if you can cook tea perfectly in front of an auditorium of white-coats you get the coveted job of assistant to some secret guy. on a motorbike, the young man and his girl head out of London north into the countryside, where life is still worth living and people are friendly.  on the way, they have to hide in some cave and sedate themselves to avoid detection by police and their brainwave scanners. They also do some rite-of-passage by jumping through a ring of fire.
It was either a short story or a novel. I read it about 20 years ago, and some vague memory of it stuck.  It's set in a future where everyone's allotted role is decided by a series of tests once they reach a certain age. They are then classified into a group which decides what jobs they will do.  Our hero rather controversially gets a perfect score in the tests. Nobody had done that in a long time. and at first he worries about what this might mean. He is sent to work for the mysterious scientists who maintain the computer that runs society. Most people don't know they exist. He is disappointed to learn he has to be their tea boy, and learn a tea making ceremony perfectly.  In the process he learns how to fool the machine, and eventually to circumvent the controls society has placed on him. He makes several visits to an area outside the control of the machine - where people are living in poverty and lawlessness.  Can't remember the author, or the name, just that basic idea, and the fact that early in the book is a very grand "tea ceremony" where he must make the tea perfectly.

What is the Physical Meaning of Commutation of Two Operators? I understand the mathematics of commutation relations and anti-commutation relations, but what does it physically mean for an observable (self-adjoint operator) to commute with another observable (self-adjoint operator) in quantum mechanics?   E.g. an operator $A$ with the Hamiltonian $H$? How can I make a macOS Mojave bootable USB installer in Windows 10? What's the purpose (if any) of "javascript:" in event handler tags? I've been making a concerted effort to improve my javascript skills lately by reading as much javascript code as I can. In doing this I've sometimes seen the javascript: prefix appended to the front of event handler attributes in HTML element tags. What's the purpose of this prefix? Basically, is there any appreciable difference between:  onchange="javascript: myFunction(this)"   and  onchange="myFunction(this)"   ? Which is correct, "you and I" or "you and me"? When the phrase is used as an object, why so many native speakers are saying "you and I" instead of "you and me"? I'm not a native speaker but I thought "you and me" is correct. Not sure if this falls into the same category, but "Just between you and me" sounds more natural than "Just between you and I". Should I retag a question with a tag that is based on the answer and not the question? Here's a scenario:  Someone asked about "How to build a SQL query to get count and blah blah blah..."  His only tag is . I added the  and  tags to it.  Someone else answered with a nice SQL statement that has a "group by" statement which seems "logically inevitable".  I proceed to add a tag . I did that on the basis that someone who searches for  will be able to find this post useful, just as I did. My concern is, it wasn't described at all in the question, nor was it implied, unlike  and .  What is the community opinion?  The scenario above is a real one . And the one who answered it nicely is Jon Skeet. Firstly I do not want to round my numbers, I am using base 10 figures so excel should have no bother doing simple add and subtract.  A|  665.110000000000000000000000000000 B|  4.990000000000000000000000000000 C|  =a1+b1 D|  670.790000000000000000000000000000 E|  1,335.890000000000000000000000000000 F|  =e1-(c1+d1)   I should get -5 however F1  returns   -4.999999999999770000000000000000   It is a financial document therefore I want to avoid rounding, more to the point. Why should I need to? I've put cell formatting to Currency with 2 decimal placed and I will get the correct display value but for all calculations I will still get -4.9999...7 which leads to further errors with conditional formatting etc. How to calculate bounce angle? I played around with it for a while, but I simply can't figure it out.  I made a tank that fires missiles, and when the missiles hit the walls, I want them to bounce off, but I want them to bounce off to the right angle.  Right now I haven't got any obstacles, the missiles just bounce off when they get outside the viewportRectangle I made.  Is the solution I'm looking for quite advanced?  Is there a relativly simple way to do it? Why does lightning emit light? What exactly is causing the electric discharge coming from the clouds to emit light while traveling through the air. I've read and thought about it a little but with my current knowledge I cant really figure what is happening at a subatomic level. In other words, what causes the emission of photons during lightning. What I want to know is, is there some sort of collisions taking place that produces the photons we see, or is it some other interaction that is causing it?. I don't know too much about particle physics, I've only read a couple of pages in the Introduction to Elementary Particles by Griffihts. So if you could keep the answer simple then that would be great. Why does a 12V 2A adapter measure only 0.358A on a multimeter? I assume that the multimeter should read 2A, why is it only 0.358A? If this is how it is supposed to be, why? If I add a load, how do I measure that this load is being drawn, does the multimeter need to be in series? Is there evidence of dark matter in our galaxy? Is there evidence of dark matter in our galaxy?  How can we measure this, say, how many percent of the center of our galaxy is dark matter?  I did not find the answer in the question Trying to find a Sci-Fi movie, probably from the 50's or 60's I’m trying to identify a movie I saw when I was very young.  It was a “Saturday Matinee” playing on one of the local stations, and I likely watched it in the late 60’s.  So I expect that the movie is from the 50’s or 60’s.  I watched it in black and white, but it could have been a color movie on a black and white set. I clearly recall a scene where scientists enter a lab and some see something move past them in a blur.  Later in the movie, they come upon themselves in the same lab where they appear to be frozen and not moving.  Then they notice that their “other selves” are moving, just almost inperceptibly slowly.  They are encountering themselves but at a completely different time scale. Unfortunately, I don’t recall much else about the movie, just the idea that they encounter themselves once with the others flashing past, and again seemingly not moving at all.  If this rings any bells with anyone, I’d love some pointers to try to track this movie down. How is Russell’s Paradox equal to the universal set? Traditional statistical tests, like the two sample t-test, focus on trying to eliminate the hypothesis that there is no difference between a function of two independent samples. Then, we choose a confidence level and say that if the difference of means is beyond the 95% level, we can reject the null hypothesis. If not, we "can't reject the null hypothesis". This seems to imply that we can't accept it either. Does it mean we're not sure if the null hypothesis is true?   Now, I want to design a test where my hypothesis is that a function of two samples is the same (which is the opposite of traditional statistics tests where the hypothesis is that the two samples are different). So, my null hypothesis becomes that the two samples are different. How should I design such a test? Will it be as simple as saying that if the p-value is lesser than 5% we can accept the hypothesis that there is no significant difference? Standard formula for quick calculation of scores I have three datasets as follows:   Dataset A can have a maximum score of 30. (Individual scores can be from 1 to 30) Dataset B can have a maximum score of 45. (Individual scores can be from 1 to 45) Dataset C can have a maximum score of 25. (Individual scores can be from 1 to 25)   The three datasets contribute equally to a final score, hence it is 33.33% each. i.e. (33.33% for dataset A + 33.33% for dataset B + 33.33% for dataset C) = 100% (final score)  I have the following scores in each dataset:   Dataset A: 22 Dataset B: 15 Dataset C: 10   Is there a quick formula that I can use to work out the final score, based on the above datapoints?   (This is not a homework question.) biblatex ieee style same authors Prime dividing the binomial coefficients It is quite easy to show that for every prime $p$ and $0&lt;i&lt;p$ we have that $p$ divides the binomial coefficient $\large p\choose i$; one simply notes that in $\large \frac{p!}{i!(p-i)!}$ the numerator is divisible by $p$ whereas the denominator is not (since it is a product of numbers smaller than $p$ and $p$ is prime).  My problem is with generalizing this argument for $q=p^n$. I'm looking for the most elegant and simple way to prove that $p$ still divides $\large q\choose i$. Prove that if $|G| = p^n$ then $G$ has a subgroup of order $p^m$ for all $0\le m &lt;n.$   Since $G$ is of prime-power order I know $|Z(G)| \ne e$ so there is an $a\in Z(G)$ with order $p$ such that $p \mid |Z(G)|$. Now, the subgroup generated by is normal since it's a subgroup of the center. How can I get this normal subgroup to be less than $n$? Unable to boot into Windows after installing Ubuntu, how to fix?
