I spent a decade of my life writing *A New Kind of Science*. Most of that time was devoted to discovering the science in the book. But another part was spent figuring out how to present the science in the best possible way—using words and pictures.

It took a lot of technology to do that presentation. On the software side, the biggest part was using *Mathematica* to create elaborate algorithmic diagrams—thousands of them. But then came the question of how to actually deliver everything. And back in 2002 when *A New Kind of Science* was published, the only real possibility was to print a book on paper, using the very best printing technology of the time.

The actual print production process was quite an adventure—going right to the edge of what was possible. But in the end we got many compliments on the object we produced. And from that time to this, that 5.5 lb (2.5 kg) lump of paper has been the definitive representation of my decade-plus of intellectual work.

But today I’m excited to be able to say that there’s something new and in some ways even better: a full version on the iPad.

When the iPad came out in April, I was involved in launching the Touch Press ebook publishing company. We’d had a basic version of *A New Kind of Science* on the web since 2003. And every time a new ebook reader had come out, I’d look to see if it could support a good version of the book.

The answer was always no. But the iPad was a completely different story.

Still, *A New Kind of Science* is a huge and complex book, and it was far from obvious that it could be delivered in a good way on the iPad without an unbelievable amount of work. But when we originally produced *A New Kind of Science*, we did it very carefully, with good clean software engineering. And, now, nearly a decade later, all that effort has paid off wonderfully in letting us build a version of *A New Kind of Science* for the iPad.

At the beginning I wasn’t sure what the experience of reading *A New Kind of Science* on an iPad would be like. But when I first actually saw it, there was one particular feature that got me really excited: it was easy to take any picture, and zoom in on it!

I and my assistants spent literally years producing all the diagrams in the book. But to keep the printed version to a manageable size (the 1280 pages of the book were the absolute limit for the binding technology we used), we had to print most of the diagrams quite small. Still, underneath, the algorithms we used generated incredible detail, most of which was invisible, except through the magnifying glass that I kept near my desk.

But now, with the iPad, I didn’t need that magnifying glass any more. I could just immediately use a couple of fingers to zoom in. And I went from page to page, looking at all sorts of diagrams, and seeing all those features that I last saw in fleeting moments more than a decade earlier on the screen of the NeXT computer on which I developed most of the book.

Many aspects of the science in the book rely on observation—on actually looking at systems in the computational universe. And I have no doubt that there are significant discoveries lurking in the details of many pictures in the book—that can now be exposed just by a simple zoom on the iPad.

There are other good things about having *A New Kind of Science* on the iPad too.

When I wrote *A New Kind of Science*, I broke it into two parts: the main text, which tells the core story of the science, and the notes, which give all sorts of details, background, and extra material—including some of my favorite technical and historical facts.

In the printed book, the notes had to be formatted quite small—and even so, they took up 300 pages. But they were so popular that we actually had to print a separate, large-format version of them. On the iPad, though, there’s no such issue; the notes are immediately accessible, and all nicely linked to the main text.

I’ve had a curious conundrum about *A New Kind of Science* for the past 8 years. When I go places, should I take a copy of the book with me or not? It’s often really useful to be able to flip to some picture or another in the book. But even though I have special bags that fit the book alongside my computer, it’s a big nuisance to lug an extra 5.5 lbs (2.5 kg) around.

Well, now that conundrum is resolved. I just have to slip a 1.5 lb (700 g) iPad into my bag—the very same iPad on which I can run the Wolfram|Alpha app, Touch Press books, and lots of other things. And immediately I’m carrying around a full version of *A New Kind of Science*. That I can refer to, show people, whatever.

I’m excited about the current iPad version of *A New Kind of Science*. And in the spectrum of current ebook presentations, I think it’s at the very high end. But there’s definitely more to be done. Between the Wolfram Demonstrations Project and Touch Press books, we can see a lot of ways to deliver dynamic computation in book form. And the good news is that with *A New Kind of Science* we already have the underlying *Mathematica* programs—all ready to integrate with the new technologies that we’re developing.

Many books are written just for the couple of months that (if they’re lucky) they sit at the front of a bookstore. I wrote *A New Kind of Science* for the long term. And as delivery technologies evolve, I look forward to seeing the presentation of the book evolve with them. The iPad version that we’re now releasing is a huge step—that I hope will allow a new level of engagement with the book and the science it contains.

Hello Stephen,

I’m an entusiast of Mathematica, and would like to know if there are plans to put Mathamatica Player in iPad and iPhone.

It would be really nice to run Mathematica applications this way.

Tks

Rodrigo: I very much doubt it – there are conditions on the app store which prevent any app from being able to execute code of any form – e.g. mathematica player, flash player…

Not true. App Store rules have changed, now you can upload apps that can execute code.

Thanks you, I made a request of Amazon and its here…cool. Portability is magical

Wouldn’t it be neat to have Mathematica on the iPad? I wonder if that is in the pipeline…

I bought the New Kind of Science for iPad…

I really get annoyed with the impossibility to do annotations!..

Please, upgrade the book!..

concerning IPad and Mathematica, we can now run our CustomerProfitabilityImprovement solution- all based on Mathematica or on Mathematica PlayerPro combined with a GUI mostly operated by icons. Using a VNC server from Jaadu. It’s amazing how this works.

Is the new Kindle 3 capable of meeting your conditions for ‘reading’ NKS?

I am delighted that NKS is on the iPad, I find this much more convenient than the hard back. The ability to add book marks and contextual annotations would be a big plus.

I should point out that it is possible to control a Mathematica session from the iPad or iPhone using an app like iTeleport. It might be even better to have a version of the front end running on the iPad, which then could link to the kernel running on another machine. You can fake this with iTeleport, but having an iPad native front end would be very nice, and not nearly so much of a technical stretch as putting Mathematica in the iPad.

Although Mathematica or Mathematica player are not (yet?) available on iPad, there are some nice computer algebra systems that you CAN get on it. The blog post below discusses a couple of them

I have a problem!

I have many questions about ordinary differential equation,but when i type my question in your site,i never give correct response of you!

How can i give to specily differential equation site? and how type my question if my mathematical type maybe is wrong

Hi!

Could you let us know what site are you trying to use and what problems you are trying to type in? We should be better able to help you with that information.

Thanks!

Hello Dr Stephen Wolfram, can you release an Amazon Kindle version? I have your hard cover, but it is hard to carry arround.

I have bought a copy of the NKS ebook for ipad the issue here is that I thought I was going to be able to see it in a normal PC too.

I am not familiar with apple stuff and I just have PC and laptops

Is there a way in which I could see the NKS ebook in a normal computer?

Kindest Regards.

David

Hi David,

You can view the NKS book online at http://www.wolframscience.com/nksonline/toc.html.
