Spreading the Word on One Wheel

Many of you know that I started riding a unicycle about two years ago. I didn't want to make the claim that I could really ride a unicycle until I could pass the first skill level as defined by the Unicycling Society of America. One way to get certified is to record yourself and have an examiner verify that you have indeed performed the required skills.

For this level, the requirements are to mount the unicycle unassisted, ride 50 meters, and dismount gracefully with the unicycle in front of you. I've been able to ride the 50 meters for about a year and a half without difficulty. The dismount has taken a little concentration since I got into the habit of stepping off forward rather than backward when I was done. But that was just a matter of paying attention to how I finished and wasn't a big deal. The mounting unassisted part has come much more slowly. Over the past several weeks, I was finally able to do it fairly consistently and was ready to make my video.

For certification, I posted a raw video, but here's a spruced up version that I hope you'll enjoy. And, of course, I couldn't do something like this wearing just any old shirt. If you have video of yourself doing something entertaining in your Hergert Numbers shirt, please share!

GeoGebra talk @ Allerton

Later this week, I'll be spreading the word at the IMACC Annual Conference at the Allerton Park Conference Center in Monticello, IL. On Saturday morning, I'll be giving a talk entitled "GeoGebra: Do You Really Get What You Pay For?" where I'll be demonstrating some of the cool things you can do with the free, open-source program GeoGebra.

Rather than print up a bunch of handouts and either running out or having a bunch left over, I decided to post the handout for my talk here.

If I see any Hergert Numbers fans at the conference, I'll be sure to post their picture!

Hergert Numbers in Orbit?

OK, Hergert Numbers are not quite in orbit ... yet. But the next best thing is to be sighted at the U.S. Space & Rocket Center in Huntsville, Alabama which is where we find Terra Stamps of Prairie State College sporting her Hergert Numbers shirt. And since the U.S. doesn't appear to be on the verge of sending much back into space anytime soon, we may have to get the Hergert Numbers trend over to Russia in order to leave the atmosphere. Until then, I think this is pretty cool.

Don't forget that you can now keep up with the latest Hergert Numbers news on either Facebook or Twitter (or both!). Keep those pictures coming!

Have youself a Hergert Numbers Christmas!

Obviously, Becca stayed off Santa's "naughty list" since her request for a Hergert Numbers shirt for Christmas was honored. I'm sure she'll be wearing it proudly throughout the new year. So, look for her to appear in a future blog post, Facebook message or Tweet.

That's right - Hergert Numbers are now on Twitter! You can keep up with the most up-to-date Hergert Numbers news by following us at @HergertNumbers.

Hergert Numbers Widget!

Thanks to the folks at Wolfram|Alpha, there's now a Hergert Numbers widget! You'll see it on down a little on the right side of the page. Try it out by finding the Hergert numbers of your favorite function.

I encourage you to help spread the word by adding it to your own web page. You can do this by going to the Wolfram|Alpha widget gallery.

Hergert Numbers @ Golden Gate Bridge

Last week, Elizabeth Meena was in California for her brother's wedding. Since the Meena's never go anywhere without their Hergert Numbers shirts, she took this opportunity to snap a picture at the Golden Gate Bridge. Elizabeth & her dad had just finished a walk across the bridge and back when the photo was taken. I believe this is the farthest west of all Hergert Numbers photos to date.

If you have any vacation plans for the end of the summer, don't forget to pack your HN shirt and get a photo and I'm always glad to add it to the collection.
