Mathematical Music

There have been a surprising number of posts here about poetry.

Here is some Mathematical Music, via Heather. Better to watch at Youtube with the lyrics visible.

Friday Funny Care of Microsoft

Microsoft has some very funny spots. Maybe it helps explain why they charge so much for some of their products.

The videos below are from the collection found here.
The embedding below only works in IE for me.




I have blogged previously about the Software Architect guy video from Microsoft.

A nice collection of Math videos on TeacherTube

My Google blogsearch for Sketchpad unearthed a nice collection of videos on TeacherTube:

Good News on the Video behind the Firewall Front!

This news via the Using ICT in Further Education blog (you may notice that Patricia is number 1 in the International Edublogger directory and that I am eight times better than that!):

RealPlayer 11 (the basic, free edition) allows you to download video from popular video sites to your RealPlayer library.

Try it from my favorites...

Now, looking at the details in the RealPlayer Library shows that the downloaded file is an FLV. There are other players that you can use beside RealPlayer to show these. I use FLV Player. You may not have as many conversion options using RealPlayer, but you can avoid the pop-ups, ads and general worry that comes from using Zamzar.

Large Numbers

I have come across three resources on this topic lately:

The first is a swf from an Australian e-card company. I believe this was the song sung to convince a woman to give up her liver in Monty Python's Meaning of Life.

The second is a fascinating set of images meant to give perspective to numbers like
one million plastic cups; the number used on airline flights in the US every six hours.



The third is the Power of 10 video, which many of us remember watching in Science class. The field of view expands out to the universe and then back in to the atomic level.



Do you have any favorite resources to give students a sense of scale?

Linkages, Sketchpad and YouTube

Nick Jackiw has a very interesting Geometer's Sketchpad sketch on linkages, which intrigued me. The whole collection is worth having a look at.

Today, I happened upon the video below. If you thought modeling the Fibonacci gauge was a challenge...

Strauss, Sketchpad, Photos, Quadratics and YouTube

I was hoping to post this from my new XO Laptop, but I have some figuring out to do about Flash, Opera, Linux and fat fingers.

However, I just had to post this video. Have you ever seen anything like it. Astonishing!
