This is Numberphile. We mainly post videos about mathematics and just numbers in general.
The Numberphile Society is a small group of viewers/helpers on Facebook (ideally 42 people).
Sorry, it exists on Facebook only for practical reasons.
These people watch videos shortly before they’re released, helping spot mistakes that may have sneaked through.
If you are interested in helping, please drop me an email with a bit about you.
Please note this is only for people who are:
1) Quite details-oriented and eagle-eyed.
2) Ideally know a little bit about mathematics.
3) Can spare time for this sort of thing (maybe watching 1-2 videos a week).
Email numberphile at gmail com with “Numberphile Society” in the subject field.
I will reply a link and password to join the group.
