Probability or The Story of Google

What are Markov chains? And why are they so useful?

Does a good job of explaining how Google works, which is remarkably simple, all it takes is a bigger computer. If you are just looking at letters, you just need a simple array with room for 26 entries. If you are looking at words, you need an array with a zillion entries, because not only do you are you using all the English words, you're also using all words from all the other languages and all the names and acronyms. And numbers, and punctuation, and symbols. And then, after you have counted all the words and populated your data base, you need to be able to answer a zillion queries simultaneously, which I suspect means you need to make multiple copies of these data bases. No wonder they're building all these data centers in my neighborhood.

And do not forget that all of this is being paid for by advertising. A tenth of a cent times a billion clicks is still $100K, and that probably happens, what? Hourly?

A couple of people mentioned:

Masayoshi Son (1957 - )
Japanese Businessman

Andrey Andreyevich Markov (1856 – 1922)
Russian Mathematician

Pavel Alekseevich Nekrasov (1853–1924)
Russian mathematician

On the downside, he drops in a couple of lines about global warming. I don't know if global warming is a real problem, but I do know that all of the measures western environmentalists have proposed are worse than useless.

It ends with an ad for Brilliant at the 31 minute mark.
