It said that this footnote only existed because he just learned he could do begin a book with a footnote. :-) So even the book wasn't about mathematics at all it was a nice self-reference, which is always cool. :-)

Probably my favourite story of Ramanujan is when G. H. Hardy went to see him, and I'll let Hardy tell the story: "I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one and that I hoped it was not an unfavourable omen. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways.

such a fascinating subject...I dont know much about maths, but when I read about Ramanujan I remember thinking this guy was one of, if not the most naturally gifted mathematicians in History. Had very little formal training, and so poor, he couldn't even afford notebooks, so had to use slates to do his calculations on, what mathematical marvels were lost on those slates, though he did of course, keep his best ideas in his three notebooks. Those slates are possibly in landfill somewhere.

124bel875ive The problem is the definition of real. Some of the words used to describe real are: not imaginary, objective, not artificial, and absolute. Imaginary implies a higher conscious, and I have no intention of weighing in on one side of that debate, but if one did exist, imaginary would be an apt term for something created by a being's mind. Objective and absolute completely breaks down at the quantum scale, it's only at larger frames of references things seem so tangible. And the number of peer-reviewed articles in favor of the idea that our universe is a simulation is immense. So, in summary, all four of those terms would have to be true for what we call reality to be real. There would have to be no higher power, we would have to not be in a simulation, and we will have to distill the probabilistic nature of subatomic particles away. Seems like that would be quite a feat to show that our reality, is actually real.

People that deny objective reality are solipsists. Solipsists justify Violence and HARM sentient beings by pretending they are imaginary. Solipsists are THE reason Earth is in trouble today. 150 billion animals per year killed and eaten by carnists (frugivores eating corpses!) is NOT SUSTAINABLE. It's a Death Cult. Again, Objective Reality. To deny Objective Reality in insanity. JUST say'n

At 10:04 Dr. Grimes says of the classic Hardy-Ramanujan series approximation to the partition function: "in fact it becomes equal [as you include more terms of the series]." However, this is incorrect, as the Hardy-Ramanujan formula is only an asymptotic approximation (i.e., the value of the kth partial sum converges to p(n) only as n --> inf for fixed k, but *not* as k --> inf for fixed n). It was actually Radamacher who, in 1937 (some twenty years after the publication of H. and R.'s original result), was able to modify their formula to make it absolutely convergent.

Awesome video! Those figures remind me of tetrominos - all the ways you can arrange four squares in a plane where each square has at least one edge connect to the whole figure. Oooh! You should do a video on polyominos! The sequence of possible configuration with one square is 1, two squares = 1, three = 2, four = 5, five = 12, six = 35, and so on. :-)

It's rather ironic that Ramanujan should be particularly well known for his work on partitions. He was an Indian, and that's exactly what they did to India in 1947. And they considered how many ways there were to do it beforehand.(BTW, Ramanujan wouldn't have had a problem with his Christmas card list if all the positive integers were his close friends. As a Hindu he almost certainly wouldn't have had one.)What, too soon?
