Earlier, YouTube maths channels focused mainly on giving nice expositions of non-trivial math ideas. But recently, two brand new theorems were presented on YouTube instead of being published in a journal.
- Proofs of the fact that
,
,
and
are irrational numbers – Burkard Polster (13 April 2018)
This is an extension of the idea discussed in this paper by Steven J. Miller and David Montague.
- A new proof of the Wallis formula for π – Sridhar Ramesh and Grant Sanderson (20 Apr 2018):
This is an extension of Donald Knuth‘s idea documented here by Adrian Petrescu.
It’s nice to see how the publishing in maths is evolving to be accessible to everyone.
