So this article is just the author complaining that he has no practice in reading mathematics. Would you be surprised if someone who never written a computer program before couldn't understand a complicated dynamic programming algorithm? Of

I love the idea! I want to try playing :) But "Singularity Chess" is an awkward name. The center of the board is not a singularity in any reasonable sense of the word. The space of allowable movement trajectories appears to be nonsingular.

It's so unmathematical to use the equal sign there... and of course there are plenty of people who live their entire lives without any of those three things. Math is also about finding structure and patterns that don't arise in any of those

With that example we should be teaching our high school students graph theory. And I'm completely in support of that. Nobody uses geometry to read a map, because geometry is about shapes and angles, not routes.

Mathematics is not about calculations. That's exactly the problem with math education, that the people designing the curriculum don't accept that.

Interesting mathematics can be taught in high schools. In fact, I've tried and had some wonderful results. See my account of it here: http://jeremykun.wordpress.com/2011/06/26/teaching-mathemati... .

Aw crap. That was in the ToS wasn't it?

I noticed that I didn't add the source, but when I wrote it I thought the source was self-evident from my mention of "Fry" and the animation style.

At least I gave the source :) And I don't claim I'm any better.

I would expect them to read it once, and bounce it back to the author saying something along the lines of "Cite your sources, please." That's certainly within Google's power, no?

I imagine they have a release process to get something on research.google.com, though. So the company is endorsing it.

Shocking, right? I demand compensation! :)

PageRank is definitely still used, although it's doubtfully the sole determinant of ranking results. See http://jeremykun.wordpress.com/2011/06/21/googles-page-rank-...

Look at the slide entitled Gmail (5), and compare the picture with the first graph on my blog post http://jeremykun.wordpress.com/2011/08/11/the-perceptron-and... It just goes to show, Google steals content without attribution just like e

I wrote a blog post with more detail, and lots of intuitive examples. see http://jeremykun.wordpress.com/2011/07/27/eigenfaces/

Sadly you need a hefty amount of it to get to machine learning that uses linear algebra in a nontrivial way.

This book spends three chapters on the mechanics of matrix operations before defining a vector space, and then it jumps into determinants. IMO this is the wrong way to understand linear algebra, and the typical path of a lot of introductory

Well, it is a blog about mathematics...
