First he determined the ratios representing the spiral pattern of the leaves and branches on an oak tree, using a cylindrical double-protractor tool of his own design. Then he copied the pattern using a computer program, and built an oak tree-shaped solar array out of PVC pipe. He next built a flat-panel array mounted at 45 degrees, like a typical home rooftop array, and attached data loggers to each model to monitor voltage.[...]
He determined the tree’s Fibonacci pattern allowed some solar panels to collect sunlight even if others were in shade, and prevented branches on a tree from shading other branches.
The hand is so versatile Matthew can grip a pen to draw pictures and write, tie his shoe laces and catch a ball.
The hand, made from high-grade plastic with a black silicone socket, literally plugs into Matthew's arm.
Two electrodes on the inside of the socket detect electrical impulses made by the muscles in Matthew's lower arm.
The signals are then beamed to a mini-computer in the palm which translates the messages into movements, replicating a normal hand.

The study found that the average price per tooth dropped to $2.60 this year from $3 in 2010.
On the East Coast, last year’s highest-paid children are now the lowest paid ones. The price of a tooth dropped 38 percent to $2.10. In the South, children also took a big hit to their piggy banks as the price was cut 21 percent to $2.60.
The price for teeth in the Midwest and West Coast remained stable. Children in the Midwest noticed a decline of 3 percent, or 10 cents, to $2.80. While West Coast youngsters actually saw the price edge up to $2.80 from last year’s $2.70.
C.J. started working out five years ago when his football coach told him and his teammates to go home over a weekend and get some exercise. He did some push-ups and sit-ups and loved it. Not too long after, he saw a P90X infomercial and loved that too. He's been working out ever since. C.J. does his own routines three times a week, after school and homework, and he's given new names to some old and boring moves, like the burpee, which involves a squat, push-up, and jump. C.J. calls that one the "shredder." He even teaches a class of (mostly older) kids at the gym near where he lives in Locust Grove, Ga.
