Numberphile (Brady Haran) · Pulse

Numberphile is a mathematics-focused YouTube channel created by Brady Haran (Australian-born and UK-based YouTuber, formerly of BBC and Nottingham University-affiliated science-communication work), focused on producing substantial mathematician-interview-driven mathematics content. Founded in 2011, the channel has grown to ~4.5+ million subscribers as of 2024 with substantial mathematics-research-community engagement plus broader mathematics-curious general audience reach.\n\nThe editorial approach combines substantial mathematician-interview format (with Numberphile featuring substantial number of professional mathematicians-and-mathematical-physicists from major research universities including Oxford, Cambridge, Stanford, MIT, Princeton, plus the broader academic mathematics-research community), substantial whiteboard-and-paper-based explanation aesthetic (the distinctive Numberphile "brown paper" visual signature), plus substantial cross-mathematical-discipline coverage from elementary number theory through topology, algebra, analysis, applied mathematics. Major Numberphile videos have covered Graham's Number, the substantial 1+2+3+... = -1/12 viral video (which sparked substantial mathematical-research-community discussion of the analytical-continuation framing), substantial Fields Medal-and-Abel Prize recipient interviews, the substantial Fermat's Last Theorem coverage including the substantial Andrew Wiles interview series. The associated Brady Haran broader podcast-and-channel network includes Hello Internet (with CGP Grey covered above), Sixty Symbols (physics), Computerphile (computer science), Periodic Videos (chemistry), plus broader Brady Haran channel network.\n\nFor a globally-mobile professional with mathematics-and-research interests, Numberphile provides substantive interview-driven mathematics content. Indian-learner engagement is substantial particularly among Indian mathematics-and-engineering students plus the substantial Indian competitive-mathematics-and-IMO-preparation community.
