Imaginary Erd-s Number DuCaDo003: I realize that this video is a bit old, so I don't know if anyone is paying attention, but can anyone tell me if there is a formal mathematical way to denote or represent Erdos Numbers? I can't seem to find one anywhere on the internet in 2020. I was thinking you could have -lowercase epsilon-(person's name) = (person's Erdos Number, that is, for example, you would say -Epsilon of Erdos equals zero- or, another example, -Epsilon of Graham equals 1. - It would look like e(Erdos) = 0, substituting e for epsilon. I don't know if epsilon is used for some other function, but this is just an example of a way you could do it. Can anyone enlighten me on this?

I find it preposterous that people are allowed to publish under fake names. It is not as bad as faking data (Golden chopsticks video, but still very bad because the person could publish fake data and you would never be able to find the original author (or a person which happens to have that name gets in trouble instead.

I don't think that final note is really valid. Someone's Erdos number can't decrease, since the original shortest path will always exist. Jerry Griggs has and always will have published a paper with G. W. Peck, meaning he will always have an Erdos number of magnitude equal to or less than 1+i.

I find this more humorous than it should be. Maybe because I pictured a governor as a mathematician. I would say that a smart governor is an oxymorin, but Pierre de Fermat would prove me wrong. I bargained with my mom for the Numberphile poster. XD

0: 26 Is anyone else smiling gleefully because he said, -He had a theory, but not a real theory, that. - in order to distinguish what he was saying about the theory to mean the colloquial sense of the term rather than the scientific?

Ronald Graham is clearly a true genius. (Watch the Grahams Number videos with R Graham on NP) Sometimes it's hard for gifted people explain to -normal- people something they truly understand. I think its mesmerizing.

At about 2: 50 Ron uses the standard Euclidean norm (L2) to suggest that 1 + i is closer to 0 than 2 is. However I think the Manhattan norm (L1) is more appropriate here, where the distance is 2 in both cases.

It kind of saddens me that we need disguise and use pseudonyms to introduce radical new ideas even in mathematic.
I have a thousand more words to add, but you know where it goes, you always knew.

seriously why is there a pattern in x=y hypotenuses' square roots' last digits?
they seem to go on forever as 2, 8, 8, 2, 0 repeated. i'm not sure why and i'd like a numberphile to help out =)

Brady, will you be uploading a Christmas special video? Maybe talk about a special Christmas number or a Christmas shape? I would LOVE to see something Christmasy!
