Hi everyone, continuing in a similar fashion to my previous maths post )) could somebody explain in layman's terms what 'wau' is. I can across it today and have seen some of the cool stuff it can do, I thought 'wow'. But what is wau? And why does it makes us go 'wow'? Sparky

Hello, In what context is the "wau" used? The acronymfinder has these answers: http://acronyms.thefreedictionary.com/WAU The softpedia has this on wau: http://news.softpedia.com/news/Wau-Is-an-Incredible-Number-252095.shtml Bertus

That was the video I saw. Wau, a greek letter which looks like an F. Whilst that video is great to show what wau can do, it doesn't explain what wau is. Wikipedia's definition makes my head implode.

Hello, This is what wolfram mathworld has to say: http://mathworld.wolfram.com/DigammaFunction.html Bertus

It is indeed an ancient Greek letter, not used anymore. It is called digamma, as bertus said. I don't know why the girl in the video calls it wau.

That's my gut feeling as well, even though I'm the one that always falls for the NPR April Fools jokes.

It is a well done video, and it is creative and educational. The importance of unity is often overlooked. It is a very special number. The give away for me was when they mentioned wau is equal to exp(2 pi i). Before that point, I wasn't really thinking too deeply because of the speed of the presentation. Then they related it to physics (E=mc^2) which was a huge red flag. Then, I went back (slowly) to every example given and wau=1 works for all cases. Yes, those will be happening soon, and we get some here at AAC too, so watch out.

For those who find mathematical purity too dry but like the link between maths and physics get hold of a copy of The Mathematical Mechanic by Mark Levi It is fascinating to see his derivation of maths from the basic physics of things eg He proves pythagoras by whirling a triangular fish tank around vertex and derives the Gauss-Bonnet theorem from a bicycle wheel.
