Stephen Hawking 1942-2018
Unsurprisingly, Stephen Hawking and his his work has regularly featured in our videos.
I imagine it will continue to do so.
Square Sums
Part Two is also well worth a look, but you need to have watched Part One.
Here's a slower look at the sequence Charlie Turner put together in Part Two.
The videos feature Matt Parker and Charlie.
Matt's book - as discussed - can be found here.

Hannah's Book
Thanks to Numberphile regular Hannah Fry for supplying some signed copies of her Christmas mathematics book - The Indisputable Existence of Santa Claus.
The book has been updated from last year with a whole new chapter, new cover, and fewer typos, according to Hannah.
The copies signed by Hannah and her co-author Dr Thomas Oléron Evans have been sent to top Numberphile Patreon supporters (you will have been messaged if one is coming!)
However if you'd like to buy the book, it's available all over the place... Or you can use the Amazon affiliate links below.

TREE(3)
The Epic (and much requested) TREE(3)...
Make sure you don't miss the extra footage - it is better than the main video in some ways!
Plus some Graham's Number back catalog - seems a puny number now!
My thoughts on the new Star Wars movie trailer
It was okay. Not amazing.
Artistic Prime Numbers
This week we posted a video on Numberphile about a very unusual prime number.
In 1996, James McKee was a mathematician departing Trinity Hall, at Cambridge.
Following the tradition of bestowing a farewell gift on the college, McKee devised a prime number with 1350 digits (the college being founded in 1350).
The numbers, when viewed in the configuration below, also depicted the Trinity Hall logo.
Here's the video:
Since it was published, I've seen the following number (I assume prime, I've not checked) which depicts the Hello Internet Nail and Gear logo. It was published on the r/HelloInternet subreddit.
It has 2014 digits, the year of our first podcast episode.
I also noted this prime (?) on the r/geek subreddit, depicting the reddit alien Snoo.

Solar Eclipse in 2009
As I write, there is plenty of interest in solar eclipses because they're about to witness one in the United States.
I won't be there, but did travel to see one in China in 2009.
While much of the country was clouded over, we go lucky with clouds and saw it from the University of Nottingham's campus in Ningbo.
While my videos do it no justice, it was one of the most extraordinary things I've seen. Don't miss out if you have the chance!
I also uploaded some raw footage here.
And more extras.
The image below is a favourite of mine because it shows the Moon's shadow over Ningbo, where we were filming (and it shows Australia, my homeland!)
More pictures from China below. Click to enlarge them.
I traveled with astronomer Amanda Bauer.
