Maths in a nutshell

Wolfram Research's Mathematica celebrated it's 20th birthday last week. I haven't used it Mathematica - Wolfram researchin a while, but it was a very nice tool to do mechanical simulations. I'm glad to learn that they now have a free viewer which plays thousands of free demonstrations and notebooks on many areas like: architecture, fractals, 3D Graphics, art, patterns, chaos, mechanics, and more.
Mathematica Player is an innovative new take on viewer applications. Rather than just a reader, like Acrobat Reader, mathematica nbp koalaor a thin runtime, like Flash Player, Mathematica Player has the full Mathematica engine embedded right there --ready to make documents come alive or to power applets. (Of course, don't forget it can read notebooks too!) Because Player-interactive documents are so easy to make using Mathematica 6 technology, thousands of these are already freely available at The Wolfram Demonstrations Project--with more supplied each day by researchers, educators, students, and professionals. Yet there's one aspect that's just like other players: it's free. Download it now.
If you need an "oranges and apples" approach... here's a bit nutty way of exercising pattern sequences. (via: Not Quite Perfect) It might look... well, oranges and apples... but it's actually a squirrel! Seriously, I had to scratch my head several times with some sequences... actually not with the sequence itself, but trying to figure use it - discover pattern sequencesout the formula. Usually we just discover the pattern intuitively, we never actually think about the mathematical formula behind that. For example, a sequence as simple as: 5, 4, 3, 2... you may know that the next number is 1, and then 0, etc... but what about the 20th number in the sequence? You may need to think of a formula to calculate that ( 6-n=x ). After shaking some rust out of my brain, I managed to get 1404 points... I have no idea if that's good or bad, but it left me with a headache.

Nice links. I used the "Nutty Squirrel" one with my Maths class last week and they loved it.

I got the link to the squirrel from your blog. It's a head-scratcher when you're out of maths-shape.
