Workshops on computational design and generative art tend to start with a sense of excitement. The participants find themselves exhilarated as they discover that forms can be made to move and interact with just a few lines of code. But then a certain point is reached, where the words “trigonometry” and “vector” are mentioned. And often exhilaration turns to despair.

Regardless of whether you believe the old “right brain / left brain” clichee that creative people are bad at math and vice versa, there is a wall of knowledge that divides the scientist from the creatives. The old mistake is to think that the scientists have all the knowledge on their side, since they can to refer to physical laws and all kinds of theorems. The artists and designers are left with “soft” theories of communication and art history, much maligned by the rational scientific community. But put a physicist in charge of an advertising campaign, and you will most likely get a spectacular failure. In fact, it will be much like a nuclear reactor built by cubist painters.

Yet aesthetics is a field of knowledge, with massive amounts of empirical data to back it up. Advertising execs and industrial designers can refer to demographic studies, ergonomic principles and historical and cultural biases as to which color best expresses joy. But the artist is sometimes left with no option but to say “it is so”, without the faintest data to back her up. Still, no creative would doubt that any artist’s method is based on a mass of internalized knowledge. It’s just a shame it’s so hard to communicate.

A simple “you know stuff, too” pep-talk will never get creatives over the mathematics threshold. Some will give up, some will find unexpected resources within themselves and yet others will learn to build on work done by others. That’s where people like Paul Falstad come in handy.

Falstad has published a rich resource of Java applets demonstrating physical and mathematical principles, many of them with source code included. One can find wave simulations, vector fields, digital signal filters, magnetostatic fields and even quantum theory. And while this is still heady stuff, at least it’s in a visual form.

Another famous source is Paul Bourke. He has published papers, algorithmic how-to's and even information on common file formats. Many computational designers acknowledge a deep debt to Bourke’s work.

Want to model organic or mechanical motion? Go pay Craig Reynolds a visit, he created the classic Boids algorithm and has plenty of data and code online. This is essential reading for learning how to describe movement in terms of intention and action, rather than just as a set of changing X,Y coordinates.

The moral? There is hope. Any student who learns to google creatively will find help for even the most obscure problem.

Interesting post…

I’m a right brain dominant person who set out to create a new number system. It took me more than 20 years – yet I did it! (Australian Numerals)

So maybe right brain people simply need to know how to switch on their math-brain?

Geometry is after all, the pinacle of math!

Best wishes,

Hi there! I was interested to know if setting up a weblog such your own: is tough to do for unskilled people? I have been hoping to set up my own blog for a while now but have been turned off because I’ve always assumed it demanded tons of work. What do you think? Many thanks

Today, while I was at work, my sister stole my iphone and tested to see if it can survive a forty
foot drop, just so she can be a youtube sensation. My iPad is now
broken and she has 83 views. I know this is entirely off topic but I
had to share it with someone!

Asking questions are truly good thing if you are not understanding anything
totally, except this post presents fastidious understanding even.

amazing insight. Really enjoyed skimming through this blog.
Keep up the good work and to everyone keep on tweeting!

Everything that is important should be part of the contract.
In Carmine Napolitano, wedding photography doesn’t simply record
how things look. All of the most important point for getting this
type of when a responsibility when it comes along to physical appearance.

Oh my goodness! Awesome article dude! Thanks, However
I am experiencing troubles with your RSS. I don’t understand why I cannot subscribe to it.
Is there anybody getting the same RSS issues?
Anyone who knows the solution can you kindly respond?

What you published was actually very reasonable.
However, consider this, what if you wrote a catchier post title?
I ain’t saying your content is not solid, but what
if you added a post title that grabbed folk’s attention? I mean Generator.X blog
Blog Archive Math lessons for right brain people is a
little plain. You should glance at Yahoo’s home page
and note how they create post titles to get people interested.
You might add a related video or a related picture or
two to grab readers interested about everything’ve got to say.
In my opinion, it would bring your posts a little
