Restoring Faith In Scientific Methods

I'm trying to work out the "new math" that must be involved with this.

""There are 10 times more microbial cells associated with adult human bodies than there are human cells, so we are 90 percent microbial and 10 percent human," Gordon said. The bacteria can help people digest and absorb food that might otherwise be indigestible."

And my brane is boggling.  Surely he meant " . . . so we are 90.9% microbial and 9.1% human . . ." ?

Robotic Flight - The Easy Way.

It's just a thought. But our robot builders and developers now have the algorithm sussed, whereby you give a robot control over it's limbs, a sense of direction, and then a directive to get from here to there as quickly and efficiently as possible.  And they do learn, quite quickly, how to get from here to there.  So why not model this crittur, and then let it sort out for itself what to do next?
