Nanoscale materials, including particles used today in stain-resistant pants and suntan lotions, are generally less than 100 nanometers in diameter. A sheet of paper, in comparison, is a whopping 100,000 nanometers thick. (nano laws) I want more stain-resistant pants (and a water-resistant jacket)! They’re truly amazing innovations that I’m fascinated by.

I have a recommendation for USC: blogs like USF
Sounds like a cool idea to me.
bunnie’s blog has a contest in which he shows a photo of a circuit board, and people have to figure out what it is. Really amazing stuff.
What the?! This stuff is actually mind-boggling!
So tonight I took in my copy of Nature from the mail and opened it up…and saw smiley faces. I thought this was the coolest thing I had seen in a while: Paul W.K. Rothemund, a researcher at Caltech, has figured out a way to cause DNA to fold into arbitrary patterns (Nature calls it DNA origami). The patterns include, of all things, a nano-scale smiley face (I’m glad to see he has a sense of humor! The article actually has a number of other very interesting patterns that demonstrate the utter generality of the technique). And when I say nano-scale smiley, I mean a smiley face that’s smaller than 100 nm across. Given that fabs struggle to get a single rectangular strip of polysilicon to print that is 65 nm, this is a really remarkable result.
512 bytes is a very small amount of code (it fits on a single sheet of paper!), compared to the megabytes of code contained in software like Windows, Internet Explorer or Internet Information Server. Three bugs within these 512 bytes compromised the security completely – a bunch of hackers found them within days after first looking at the code. Why hasn’t Microsoft Corp. been able to do the same? Why? xbox-linux
I’d never heard of this game until I stumbled upon it on Amazon.com. It sounds awesome! Anyone have it? Read the rest of this entry »
