## What is Numberphile?

Numberphile is an educational YouTube channel featuring videos that explore topics from a variety of fields of mathematics. The videos are produced by Brady Haran, a former BBC video journalist and creator of Periodic Videos, Sixty Symbols, and several other YouTube channels.

### Are Numberphile and Computerphile related?

Computerphile is the sister channel to Numberphile, featuring videos about computer science. Haran is minimally involved in the channels video creation, with most being directed and produced by Sean Riley.

#### How is tree 3 calculated?

With two seed colors, you can build three trees before you build one that contains a previous tree. So TREE(2) = 3. You might be able to guess where it goes from here. When you play the game with three seed colors, the resulting number, TREE(3), is incomprehensibly enormous.

**What is the most evil number?**

The exact number is 1,000,000,000,000,066,600,000,000,000,001. If you do not see it right away this so-called infernal number has a one followed by 13 zeroes, followed by the much-feared number of the beast (666), followed by yet another 13 zeroes, and a trailing one.

**Who is the girl on Numberphile?**

Fry has appeared in several videos for a YouTube mathematics channel, Numberphile, run by Brady Haran. She has also made an appearance on his podcast: The Numberphile Podcast.

## What do you call a person who loves math?

People who study math are called mathematicians, but if you are describing someone who particularly loves math, you could use something like mathematicaphile, or mathphile.

### How do we know tree 3 is so big?

TREE(3) is big because TREE(n) is very fast growing function, i.e. TREE(n) is humongous even for small n. The unenlightening answer is which is a number that, in many ways, is not dissimilar to .

#### Is tree 3 even or odd?

Introducing TREE(3) TREE(3) is so gargantuan, so incomprehensibly massive, that no human can ever visualize it, understand it, or conceptualize it. At least, we know that TREE(3) is finite and can be proved even with the help of finite arithmetics.

**Who decoded the Enigma machine?**

Alan Turing

Alan Turing was a brilliant mathematician. Born in London in 1912, he studied at both Cambridge and Princeton universities. He was already working part-time for the British Government’s Code and Cypher School before the Second World War broke out.

The New York Times has said, “At Numberphile, mathematicians discourse, enthusiastically and winningly, on numbers”. The channel has featured mathematicians, computer scientists, scientists, and science writers, including:

**What is the numberphile2 channel?**

Haran also runs the “Numberphile2” channel, which includes extra footage and further detail than the main channel. The channel was nominated for a Shorty Award in Education in 2016. The New York Times has said, “At Numberphile, mathematicians discourse, enthusiastically and winningly, on numbers”.

## What is the Numberphile Podcast?

In 2018, Haran released a spin-off audio podcast titled The Numberphile Podcast. The Numberphile YouTube channel was started on September 15, 2011. Most videos consist of Haran interviewing an expert on a number, mathematical theorem, or other mathematical concept.
