I'm 100% not joking, I once was stuck the the proof of a theorem for a whole week going at it and still wasn't able to prove it... until I dreamed of the solution, woke up at like 3 am, quickly wrote a skecth of my dream's proof and went back to sleep. The following morning I checked that path and boom, there it finally was the solution.

Weirdly enough, this happened twice, although that second time I didn't woke up at 3 am, just in the following morning as usual.

    I read somewhere that Mick Jagger (or maybe it was Keith Richard) wrote the riff of Satisfaction in his sleep.

    He woke up, grabbed a tape recorder and went "Bum bum. Bumbumbuummm bumbumbum." And sang the one line "I, can't, get noo, sat-tis-fac-tion." And then went back to sleep.

    Forgot about it the next morning till they were at band practice and someone found the tape and played it.

    I too have written down riffs from my dreams. Also I am not a famous rock star.

    Draw your own conclusions.

    Satisfaction was a hit because Jagger has skill, not because he dreamt it.

    I didn't say it wasn't both. If Keith didn't dream it, Mick's skill couldn't have made it a hit because it wouldn't have existed.

    I'm trying to figure out what point you're trying to make and there doesn't seem to be one

    That dreaming a riff is not difficult.

    Wait a minute, are you telling me you can dream about literal scantily clad women without a single summation, integral, or root?

    Can someone explain the formula? Is it real? What does it do?

    I miss PugJesus :( he would usually explain these things

    Ramanujan's pi formula.

    Similar formulas were used to calculate digits of pi very fast etc.

    I see. It makes so much sense now.

    Thank you

    There are many different formulas for deriving digits of pi, and the history of mathematics has a bunch of people trying to brute force inefficient formulas for pi out to a few digits, as they develop more efficient methods.

    Archimedes drew a circle and put some polygons around the inner and outer limits to determine that it was somewhere between 22/7 and 223/71, accurate to within 2 digits. That general polygon method was used by Ptolemy to calculate out to 3 digits, and used by Chinese mathematician Zu Chongzhi to estimate pi at 355/113, accurate to 7 digits.

    The polygon method was very tedious, requiring many, many calculations in order to advance just a few digits.

    The Liebniz formula was a breakthrough (discovered by Indian mathematician Madhava of Sangamagrama), because discovering that pi/4 was equal to the infinite series 1 - 1/3 + 1/5 - 1/7 . . . meant that someone could calculate some number of digits accurately, and then continue the calculation in a way that reports what is known so far, and can continue down the line towards a more precise result. Still, by itself, it was a very slowly converging algorithm, requiring 5 billion terms just to get to 10 digits of accuracy. Mathematicians got to using other tricks (that, if I'm being honest, I don't understand) to make it faster.

    Then Ramanujan discovered series that were rapidly converging (including the one in this meme) where although calculating each term might require a lot of calculations, it would spit out 8 digits for each term you fed it. It became the preferred method for calculating digits of pi, and when computers were developed, they were able to make use of that computational efficiency. It still remains the basis for how a computer will calculate a few million digits of pi.

    PieFed did some policy change on... weighting votes for people who vote thousands of times a day, or something like that? PJ said that made him want to change instance again, but he'd done that a few times already and couldn't be bothered with the process again. (this is from memory, i haven't double checked while writing)

    Um, actually... I think the square root operation takes precedence over the division.

    Chai + Psi + delta 9 (39-sigma-nu) Pi 3 {nu sigma kappa percent divide times epsilon delta 83}

    The meaning is complex, but the themes are clear:

    Chai + Psi + Delta9

    Tea, Psychic powers, and the Delta-quadrant / Deep Space Nine: Obvious Star Trek (Voyager/DS9) reference.

    (39 sigma nu) Pi 3

    Miku (Japanese: "3" "9") is a new singer with Sigma tendencies and released a pie 3 years ago

    nu sigma kappa percent divide times epsilon delta 83

    This new japanese sigma character uses their money ("cent") to polarize ("divide") the press ("times") by using Delta flight 83 (Paris <-> Atlanta)

    Putting it together

    Miku Hatsune released a pie 3 years ago, which was critically acclaimed and condemned after they were caught watching Star Trek on a Delta airlines flight to Paris from Atlanta.

    My friend said he had a dream where he suddenly understood the meaning or purpose of existence, and it was simple and clear, but when he woke up he couldn't remember it. It wasn't 42.
