## My Post on the 300th Anniversary of the Death of Gottfried Leibniz at the Wolfram Blog

My post on the 300th anniversary of the death of Gottfreid Leibniz just went live at the Wolfram Blog. Check it out.

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.

(See also my post Who Among You are Geek Enough to Decorate Your Easter Eggs in Mathematica?)

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.

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:

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.

- Eggs Colored by Gradients (a more advanced version of my initial one) by Kathryn Cramer & Michael Schreiber
- Eggs Colored by Sinusoids by John G. Cramer, Jr.
- Eggs Colored Using Polynomials by John G. Cramer, Jr.
- Eggs Colored Using the Reimann Zeta Function by John G.Cramer, Jr.
- Elementary Cellular Automaton Egg by Michael Schreiber
- Eggnimatica by Fred Klingener

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

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!

I suppose I should mention that since September, I've been a consultant for Wolfram Research, makers of Mathematica. I don't think I'd mentioned that.
