Subscriber number 300,000

Today Numberphile reached its 300,000th subscriber.

It's always hard figuring out exactly who the milestone subscriber is - but I think number 300,000 may have been Jordan, from London, Ontario.

Jordan told me: "I saw you enigma machine video when someone posted it on Reddit today and am slowly working through your other videos. I really like channels such as yours (or CGPGrey, Minute Physics and the like) with little bite size learning opportunities."

Numberphile reached 200,000 subscribers in November - here is an article about person number 200,000.
