Brady John Haran (born 18 June 1976) is an Australian-British independent filmmaker and video journalist who produces educational videos and documentary films for his YouTube channels, the most notable being Computerphile and Numberphile.
Haran is also the co-host of the Hello Internet podcast along with fellow educational YouTuber CGP Grey.
2002
In 2002, he moved from Australia to Nottingham, United Kingdom.
In Nottingham, he worked for the BBC, began to work with film, and reported for East Midlands Today, BBC News Online and BBC radio stations.
2007
In 2007, Haran worked as a filmmaker-in-residence for Nottingham Science City, as part of an agreement between the BBC and the University of Nottingham.
His "Test Tube" project started with the idea of producing a documentary about scientists and their research, but he decided to upload his raw footage to YouTube; from that point "Periodic Videos" and "Sixty Symbols" were developed.
Haran then left the BBC to work full-time making YouTube videos.
Following Test Tube, Haran decided to create new YouTube channels.
In his first five years as an independent filmmaker he made over 1500 videos and in 2012, he was the producer, editor, and interviewer behind 12 YouTube channels.
Haran frequently collaborates with well-known academics and professionals.
Haran's videos are often in the format of a casual interview in which Haran and an expert discuss subjects relevant to their work.
2008
Started in June 2008, Periodic Videos is a series of videos about chemical elements and the periodic table.
Working with Professor Martyn Poliakoff, Haran's videos explaining chemistry and science for non-technical persons have received positive recognition.
Together, they have made over 500 short videos that cover the elements and other chemistry-related topics.
Their YouTube channel has had more than 159 million views.
Also, Haran and Poliakoff authored an article in the Nature Chemistry journal and an essay on Science journal discussing the impact of The Periodic Table of Videos.
2009
The first video was released in April 2009, with the original run of videos focusing on commonly used physics notations.
Since then, videos on topics such as the greenhouse effect, the age of the universe, and several on black holes have been released.
2011
Martyn Poliakoff received the Royal Society of Chemistry Nyholm Prize for Education in 2011 for work taking chemistry education to a wider audience; this included his work with Haran on The Periodic Table of Videos.
Sixty Symbols is Haran's YouTube channel for physics and astronomy.
Started in October 2011, Numberphile features videos that explore educational topics from a variety of fields of mathematics.
It is currently Haran's most subscribed channel.
In the early days of the channel, each video focused on a specific number, but the channel has since expanded its scope, featuring videos on more advanced mathematical concepts such as Fermat's Last Theorem and the Riemann hypothesis.
Haran maintains the Numberphile2 channel as well, which features extra footage from the main channel, as well as The Numberphile Podcast.
Deep Sky Videos, started in October 2011, is Haran's astronomy-focused channel.
It is similarly formatted and has some of the same contributors as Numberphile and Sixty Symbols.
In September 2022, the channel finished a series of videos on each of the 110 Messier objects, which had been a goal of the channel since January 2012.
Computerphile is the sister channel to Numberphile, featuring videos about computer science.
Haran is minimally involved in the channel's video creation, with most being directed and produced by Sean Riley.
Haran continues to maintain the Test Tube channel, now titled nottinghamscience, as a place to post extra footage and outtakes from Periodic Videos and Sixty Symbols.
He also runs channels for his podcasts Hello Internet and The Unmade Podcast.
Haran has several channels that have been inactive for several years, which are Words of the World, Backstage Science, Psyfile, PhilosophyFile, Bibledex, FavScientist, and foodskey.
Brady Stuff is Haran's channel for personal videos and is a self-described "dumping ground for clips that don't quite fit anywhere".
2014
Haran launched the YouTube channel Objectivity in late 2014.
The videos feature the discussion and handling of historic objects and manuscripts, often from the archives of the Royal Society, though other historic museums and organizations have also been featured.
Haran is the on-camera presenter for the channel, in contrast to his other channels where he is a behind-the-camera presence.
Keith Moore, the Head Librarian of the Royal Society, is prominently featured.
In January 2014, Haran launched the podcast Hello Internet along with co-host CGP Grey, another YouTube educational content creator.
2017
On 22 August 2017, Haran launched his second podcast, called The Unmade Podcast, and on 11 November 2018, he launched his third podcast, The Numberphile Podcast, based on his mathematics-centered channel of the same name.
Brady Haran studied journalism for a year before being hired by The Adelaide Advertiser.
