An easier way to calculate x^4-y^4 would be to factorise it to (x^2+y^2)(x^2-y^2).

Would be great if they brought together a good oceanographer like him with a atmospheric physicist to get the whole picture

58:10 goldbach requires proving the existence of 2 primes that add to 2z, not finding them. The professor has only proven that you cannot find them, not that they don’t exist.
@TillerSeeker28 күн бұрын
I would choose to put the matter this way: "Existence in principle" is not necessarily the same as "existence in fact." Numbers can exist in principle irrespective of whether or not those same numbers can somehow be determined, written down, or otherwise computed. In fact, I believe that it's safe to say (as I believe that the Professor is arguing) that only a miniscule fraction of the infinitude of whole numbers can actually be written down and that the probablity of a number in the infinite universe of possible numbers being capable of being written down is effectively zero.

1:45 how do you know that the last eigenvalue is 3?
@LukeFlavel12 күн бұрын
Because the sum of the eigenvalues is equal to the trace of the matrix (the sum of a matrix's diagonal components, which in this case is 2+1+1)

z_n should be z_i in the formula right? The integral symbol would also more correctly be a contour I think. Either way thanks for all these lectures it is highly appreciated!

interesting, never thought of the vertical lines along the surface of hyperboloid has the parametric function x=t, z=t y=1/-1, when you draw the hyperboloid on maple or matlab, it never grid that way.

I am sorry but i didnt get where did the 1728 constant emerge? I know where did the 1729 get from (its just 1728 + 1) but where do the 1728 come from? Please dont post replies about "integer complexity" of (1+1+1) * (1+1) and so on :D i know that its1728 == (3^3) * (2^6) but i just didnt hear the origin in the Gaussian resampling and multi dimensional rudimentation.

20:40 (1/2) i got a little different output in my classical sigma-delta calculator for these 2 random numbers ... 8.5397342226735670654635508695466 [ omitted digits my calculator didnt show] - maybe i should change the range of integration in the exponent part... I have heard about the limit O(NlogN) a long time ago, showed in signal processing classess with DFT and Parseval (Parceval?) power preservation theorem - thanks that in practical you made it twice as fast :). Usually when people face that big integers they are looking for some other thing than a multiplication or they can suffice with some fast HW (fpga?) high order (2kbit 4kbit 256kbit) implementation for security reasons :) Regarding Kolmogorov - at that time in the soviet (USSR/CCCP) there were many scientist showing work proving the state of the party either in agriculture or in biology that nobody could deny - i am sure that Kolmogorov could have also stated that O(n^2) is the slowest of multiplication algorithms as children can do it that way and nobody would bother to object :)

you don't really to simplify that much it make student confused. you still can get the same answer in the end. Make sure don't do that next time.

Suppose a group of 20 students are enrolled in one or more of the following courses: 8 in Algebra, 12 in Biology, and 11 in Chemistry. If 5 students are enrolled in all three courses, how many students are enrolled in at least one of these courses? help me with this please
