Why Shells Don’t Break When Dropped

Monday, April 6th, 2009

Chalk is super easy to break (as any fourth grade can attest to), yet a shell, made of the same material, stays largely in tact when dropped from around five feet up (enjoy the slow motion video from the high speed camera we brought along below).

So why doesn’t it just crack? Turns out there are some crazy nanostructures at work … Here’s a peak at what’s under the surface (at the nano level):

And here’s a bit more information from the GE nano site:

Seashells are naturally self-assembled structures, growing gradually over the lifetime of the creatures that live inside them. By studying this behavior at the nano-scale, we can one day develop high-strength ceramics that are light yet also durable, and enhance the performance of our products, such as gas turbine blades.

Digital Asset Management

Thursday, March 12th, 2009

I was especially interested in talking to the asset management guys for two reasons:

  1. I’ve been thinking about spimes/blogjects for a few years now. (In the words of Bruce Sterling, “In a world of spimes, even the simplest objects – furniture, cutlery, power tools – will be little more than material billboards for a vast, interactive, postindustrial support system.”)
  2. I just read about how ants deal with traffic and have been generally fascinated by emergent systems since reading, appropriately enough, Emergence. (One of the most interesting findings in the ant study is that ants don’t really overtake one another, even when the ant in front is going slow. That’s because they are working in the best interest of the system as a whole, not as individuals.)

So … What does this have to do with trucks? Well, for one, part of the goals of what Veriwise is up to is to create systems that can both communicate with the world at large, but also allow individuals to communicate knowledge directly with one another without a central hub. What’s more, they are looking at biological systems for cues in how to help systems organize on the fly. There’s about a million more things to talk about in regards to what we saw in the “trailer of the future”, but I’m going to hold off for a bit and try to organize my thoughts into more logical chunks. Just wanted to get these two down for now.

Nano Coatings

Thursday, March 12th, 2009

So I posted the lotus leaf video to show the inspiration, and here’s the vide of the GE nanocoating in action (slow-mo action no less, thanks to our super highspeed camera).

Pretty rad.

Update (3/25/09): I was watching this video again and it would be pretty awesome to do a music video with something like this.

Lotus Leaf

Thursday, March 12th, 2009

I’ve never actually seen a lotus leaf, but apparently it’s got pretty amazing water repellance. It’s inspired some nanotechnology I’ll talk about a bit later, but first check out what it can do:
