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 everyone else.

I am trying really hard to ignore the Futurama picture. Really hard!

Wait, they just used your graph and didn't even contact you about it?

Shocking, right? I demand compensation! :)

My day-to-day programming consists so much of process and simple boolean logic that I hardly ever use math more challenging than 1 + 1 and 1 != 0. It's great to review how math can greatly influence the potential of your code.

My experience is that people who are aware of opportunities to use math find them. And people who are not aware conclude that they weren't really there.

For example are you a web developer? Have you started using A/B testing yet? If yes, that's math. If no, then you are in a position to make your employer a substantial amount of money.

For another example my very first project in my first programming job required me to build a set of canned reports. There was one user request which turned into, "We want to do this, but don't know if it is possible." I wound up using inclusion-exclusion techniques that I'd learned in grad school to solve that problem! (The problem was how to ship a local database without detailed information they shouldn't have about the rest of the company, and yet still be able to present reports comparing themselves to the rest of the company. And those reports had to drill down. So if you were responsible for 5 sites you'd be able to generate those reports for everyone that you could see, or for each site individually.)

It's one guy who happens to work for Google, rather than the whole company.

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

Seeing PageRank discussed reminds me of a piece of fun trivia. The idea for PageRank came out of the success of the Science Citation Index, which ranks papers according to how often they have been cited. The idea of trying to study the structure of citations in academia came out of people who were inspired by a 1948 essay, As We May Think.

But that essay's main topic was an imagined technology called memex, to be implemented with an automated indexing system and microfilm. This technology is the first description of hypertext, which inspired multiple technologies. The second successful consumer application that I'm aware of that used hypertext was the web. (The first was HyperCard from Apple.)

Thus Google started as the application of one set of techniques inspired by As We May Think to a technology that was also inspired by As We May Think.

See http://www.theatlantic.com/magazine/archive/1945/07/as-we-ma... for the essay itself. Do keep in mind that it was written one year after the transistor was invented, but the author already had 2 decades of experience with computing.

What do you expect them to do? Somehow do an image-similarity search throughout the web for every image used in papers by their employees?

BTW completely feasible with Google's resources. Can be fully automated, too.

Yeah, it's not like they just have a giant image search engine laying around!

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?

My mathematician friend pointed out that all that "research at google" requires "experience with large data sets and quantitative analysis". They want statisticians, not mathematicians.
