Tyler Cowen loves Machine Learning

isomorphismes:

Tyler Cowen says that super hackers will benefit from improving computer technology and reap the high wages of the post-recession economy.

I’m sorry to say I too have used the lazy robo-programmers metaphor. That was uncareful non-thinking on my part.

Trying to be more logical, what should we really conclude from the assumption that observed ↑ growth in “computer stuff” will continue apace?

You know, many people think that mathematics is so complicated. This is wrong. Mathematics is an extremely simple approximation of the world. The world itself is more complicated than anything we can think of.

How to Give Prosthetic Hands Touch Sense
Although prosthetic hands give amputees a way to grasp objects, they do not offer a sense of touch. That means the person has to watch his or her robotic hand as it reaches to push or pick up an item.
Now researchers at the University of Chicago might have found a way to add touch to prosthetic limbs. The research, which appears in the Proceedings of the National Academy of Sciences, is funded in part by the Defense Advanced Research Projects Agency, and it’s not hard to see why the military would be interested. Beyond dreams of cyborg warriors, there’s the more prosaic matter of helping injured veterans. Read more

Draw a perfect triangle on a piece of paper, and then draw around the triangle free-hand. Try to make each new shape closely match the previous one, including its imperfections. You’ll find wavy patterns developing (just like doing the same with straight lines) which makes a nice picture.  But can you manage to do all this, with the ultimate goal that after 50 lines you will reach a perfect square?  This animation shows a computer program having a go.

Video portrayal of the smooth topological charge density of an empty vacuum at Minute 26.

In other words, this is what the empty space between the quarks looks like.

Derek Leinweber discretized QCD theory (that is, put it on a lattice) and did some computations of what that looks like. One conclusion of quantum chromodynamics is that empty space is a wildly dynamical medium due to virtual particles.

The universe is a song, singing itself.
