Comment Re:Dean Kamen - Luke (Score 4, Informative) 173

I used to work at DEKA. I didn't work on the Luke arm, but I got to talk to the engineers and a couple of early adopters. I think it is a great idea for an artist. The arm's controls are modular. They accept many different kinds of inputs, and the actions are even programmable with macros. You can get hand, wrist, forearm, elbow, upper arm, or shoulder configurations. It is as light as a 50th percentile female arm (including the batttery!). It's precise enough to pick up a grape without crushing it. It allows enough finesse in multiple degrees of freedom to allow a double-amputee to eat cereal without spilling it (which Dean Kamen jokes even he can't do :) I saw a guy use a macro to control an electric drill to handle the changing torque while he controlled how fast the drill went. I think it would be a great choice for an artist.

Comment Salt molecules? (Score 2) 116

Salt is a crystal formed by ionic bonds, there's no such thing as a salt molecule. They must be making holes small enough for a single sodium ion. Not sure why they need to tailor the holes for each chemical, though. Just make them a bit bigger than water molecules, right? Than I guess a second filter that's a bit smaller, to remove contaminants that are smaller...

We were taught the 4 elements, along with several different atomic theories, and a couple non-atomic theories (that is, that materials are continuous instead of being made of smaller parts like atoms). We were also taught several theories of celestial mechanics including epicycles and angels. Some class time was specifically dedicated to debating random philosophical ideas students came up with; in fact extra time was scheduled outside of class for several professors and any students who wanted to show up. I was also taught about 6 versions of creationism (from Idimmu Xul's sibling comment), and a few strains of evolution like punctuated equilibrium. I also was taught a lot of philosophy from Aristotle to Camus, a lot of theology (mostly Christian of some form, but a lot of it was inconsistent) etc.

In addition I learned modern physical theories like quantum mechanics (chemistry, cryptology, and physics), general relativity (with worked examples of real systems like GPS), and post-Mendelian genetics (incomplete dominance, linkage, maternal inheritance).

Because of this, I knew my way around the "space" of various fallacies, and I am familiar with what evidence supports which theories. With years of defending my ideas in various fora, what I have concluded is true is a young-earth "literal 6-day" creation, and a personally involved, omnipotent, creator-savior God. My point here isn't to start a debate. I'm just pointing out that you can't predict people that well.
