So- I was going to treat you all with a nice brain-dump style posting about Scheme-style Quoting in Haskell. But Wordpress is being bitchy, so it’s going to take a while, disregard any spam in your RSS feeds, it’s unintentional, I promise.

 

Sorry.

Basic Math, how to use numbers any day.

Filed under: Math — jfredett @ 5:35 pm

On reddit today, there was a comment about a radio personality who argued with a Mathematician about how percentages work, specifically about how percentages are combined. I replied with a short explaination of how 35% + 15% = 55.25% and not latex 50%. Shortly thereafter, there were half-a-dozen comments, ranging from “That explaination was longwinded/overcomplicated”, to “Thanks, that really made the idea clear.” I realized that, while I don’t hold a Teaching License, or Advanced degree in math, I am pretty good at it, and maybe teaching a bit of basic, useful math or programming that anyone can understand and use might be a pretty popular topic for blog posts, enter the new Sporadic Series “Basic Math, how to use number any day.” (To bastardize the tagline from Numb3rs, which is an excellent show, by the way).

The posts will be aimed at laypersons with no mathematical experience beyond 10th grade or so, we’ll talk about geometry and algebra, basic statistics and numerical stuff, maybe even some more abstract stuff, but always presented from a practical point of view.

For the inagural post, Let’s talk about percentages, we’ll aim to look at percentages from a qualitative, practical viewpoint.

New digs

Welcome to the new site, posting will soon restart after the admittedly long hiatus.

To update the crowd, I’ve recently been working with Android, the Google Phone platform, specifically working on a simplified interface for interphone communication via the GTalk interface. I’ve also been fiddling with GPS stuff. I’ll be posting about that soon, and about a decentralized persistent game I’ve been hacking on in Haskell.
