Say it with Math: Mathematica 7 Home Edition released!


Just in time for Valentines Day, Wolfram Research releases Mathematica Home Edition for $295 (chocolates not included), a small fraction of the full professional edition price: Get it now your own and make your valentines with Mathematica! Find the true mathematical expressions of your love! (Or test out that new sexual geometry without injuring yourself -- just kidding.)

Read all about it at MacWorld, MacNN, and Business Week.

My son Peter is really thrilled that decorating Easter eggs with Mathematica, something that he thought up, is used on the announcement page as an example.

Using Mathematica to Analyze the US Election

Jeff Hamrick of the Wolfram Research Special Projects Group has done a blog post giving instructions for using Mathematica to analyze the US Presidential Election. He shows how to pull polling data into Mathematica and how to use some of the Mathematica 6 data libraries to create your own Red State/BlueState maps.

I think this is very interesting stuff because, for those of you with Mathematica out there, you don't have to rely on how other people choose to analyze and map this data. If you have questions of your own you can introduce your own data and draw your own maps. I will be very curious to see what people come up with.

Who Among You are Geek Enough to Decorate Your Easter Eggs in Mathematica?

I dare you. Send your Mathematica egg notebooks to me. This activity, begun last night and avidly pursued this morning, has proved wildly popular with my children who are threatening to run me out of toner in my color printer.

Here's mine:

Easter Egg made in Mathematica
(Mathematica notebook.)

Now show me yours!

UPDATE: Michael Croucher at Walking Randomly has risen to the challenge and put me in an egg. There will be a number of other Mathematica-generated eggs available via the Wolfram Demonstrations Project  next week (URLs TBA) including three fancy ones by my dad, John Cramer. There have also been forays by users of Maple and Sage.  Also, see some real math on real eggs.

URL UPDATE, 3/17/08: Michael Trott, whose book inspired my son to ask for Mathematica-generated patterns on eggs, has made an egg notebook of his own and added it to his Mathematica Guidebook website. He's made a very elaborate notebook which will be expanded and included in the Version 6 edition of the Mathematica Guidebook for Graphics volume.

(Those without Mathematica can view and play with these egg notebooks using the freely downloadable Mathematica Player.)


Also,  there are now a number of egg notebooks on the Wolfram Demonstrations site, with more on the way in the next couple of days.

Watch this space: there are more that aren't up yet.

A Visualization of the Effect of the Fed Rate Cut

Jason Cawley, whom I know through Wolfram Research, has created a neat visualization of the various effects of interest rate cuts by the Federal Reserve. I have discussed various financial news with Jason in the past, and he has written me long interesting letter. So I'm particularly pleased to see his analysis of this one on the Wolfram corporate blog.

Here's the link to his detailed blog post, "Analyzing the Fed Rate Cut in Mathematica," and here's a link to his interactive visualizations on the Wolfram Demonstrations site, entitled Macroeconomic Effects of Interest Rate Cuts.


UPDATE: Congrats to Jason, who made the Wall Street Journal blog!
