"ln(4)" is the natural log of 4, so it's the solution to the equation e^x=4, where e ~ 2.71828... also known as Euler's number[0].
Reading further in the post will explain where that quantity comes from, and why it's significant, but if you have any questions you can ask them via the comment box on the article.

Yes of course, thank you. I am so used to seeing the word "log" written out in things like time complexity/Big O analysis that I forgot about the natural log - ln. Cheers.

[0] The constant "e" turns up in lots of places, you can read more about it here: https://en.wikipedia.org/wiki/E_%28mathematical_constant%29
The usual examples for how Euler's number turns up are to do with calculus and compound interest, but there are many other.
