DiscreteIdeas moving

Well, I’ve kept the discreteideas.com domain for a few years after my last post here, and it doesn’t look like I’ll be adding much to this soon, so I’m letting the domain go.

Fractured Memories

Some fractions are a part of everyday life; dimes, quarters, nickels, hours, minutes, seconds, etc. These are relatively easy to manage mainly because we deal with them so often. Everyone just “knows” that 1/2 is 0.5, and 1/4 is .25, and 1/10 is 0.1; we’ve had it ingrained in us through massive amounts of repetition. I go one step further; I can usually estimate the decimal equivalent of just about any fraction that comes up in my life. Super useful? Maybe not, but it has good show-off value, and I think it’s fun!

Elegance in motion

Every once in awhile, I come across a video (usually on Youtube, isn’t that where everthing ends up) that quite elegantly illustrates something math-related. I haven’t been collecting them long, but I thought I’d share a couple of them with you all. Please enjoy them as much as I have.

Mom was right

Ah, Mother’s Day. Admittedly, Math isn’t the first thing you think about when scrambling for that 1-800-Flowers phone number (I always forget that one) or that last box of chocolate from the drugstore. However, one of the memories that sticks in my mind most about my Mom is arguing with her about Math during dinner about .9 repeating and 1. Before you think we’re crazy, please keep in mind she’s a Math teacher, and I have some small interest in the subject myself. So here’s to you, Mom. I finally realized you were right some time ago, but don’t think I ever said so.

Tax Bracketology

Now, how could the Count pass up a chance to talk about that most numerically significant time of year, Tax Time!? With lots of talk about rising tax rates and socialism this year, I thought it might be fun and informative to take a look at tax tables from previous years and compare them to recent times.

Pi for lunch?

Happy Pi Day! Yes, it’s that time of year again when the month and day (in the American form of date representation) for those legendary 3 digits 3/14, also known as the beginning of the mathematical term Pi1. Being The Count, however, I’m certainly not satisfied with just one Pi Day each year, or just matching 3 digits of Pi for my festivities. No, I must venture forth to find other Math-related dates to share the joy that is the geeky holiday.
