Wolfram Alpha a Google Killer? Not… Supposed… To… Be

I’m getting tired of reading about whether Alpha is a Google-killer. I’ve seen Stephen Wolfram’s presentations a couple of times; he’s quite careful to say that it isn’t. There’s a fundamental difference that many people out there are just missing. Google is a search engine. Alpha looks like a search engine, but it isn’t; it’s all about curated data, and the analysis of that data. What’s the difference? Look at one simple query: “earth circumference”.

Hacking Primes in Mathematica

This morning, Tim Bray tweeted about a post on prime numbers and Benford’s law. To cut the esoterica short, one of the big problems in prime numbers is that people don’t know how they’re distributed.

Math really doesn’t “know anything” about bases, so if this idea doesn’t generalize to bases other than 10, it doesn’t mean much.
