For hundreds of years, Euclid's geometry disappeared with the fall of the Roman Empire. But in Constantinople, Islamic mathematicians, including Al-Khwarizmi (who gave us the word "algebra") worked long and hard on proving the Fifth Postulate.

With Regard to the last Episode I'd always Assumed that the most Influential Book after the Bible [in Terms of Impact on Human History] had been the Communist Manifesto by Karl Marx but that's probably my Political Bias talking.

This continues to be super engaging, and the end of the episode continues to come far sooner than I want it to. So, good job, especially to the script writer!

Why is the Atlantic west of Gibraltar dark green at 1:30? And Britain ocean..

Why haven’t you guys made a shirt for “Why let a little blank get in the way of a crusade?”

Lol. I see it, too. I guess that Britannia really does rule the waves.

Minor nitpicks: At 2:13, -pi/2 is displayed on the number line between +1 and +2 (approx +1.3). It should be approx -1.6. At 6:55, the black sea is coloured as land and crimea is coloured as water. Otherwise, good stuff :-)

How do you accidentally steal something from the Vatican archives?

While you’re ransacking their library you accidentally grab it instead of the sacred texts you really wanted.

how many ep"s of non euclidean geometry will there be ?

If they had thought me how to do quadratic in Euclidian terms, I might not have flunked math.

Around 1:30 , there is an image of a map which has the region of earth to the far left as shaded in green. Is there a reason for this, or was it just a mapping error?

Back then the Atlantic was dry land and Great Britain was a sea. One of thoses forgotten facts of history brought to you by Extra History.

You make math fun! :D I did almost all my calculus homework during super hero tabletop role-playing sessions, and had over 100% average for both terms, because I was having fun. You really are helping. :)

why was putting irrational numbers on the rational number line so absurd to the greeks? imo \pi is a bad choice as an example of irrational number as it was not known to be irrational at the time, btw the greeks did know how to construct 2^0.5 and move it "onto the number line" through their straightedge and compass constructions so why was this concept so radical?
