We are deeply saddened to learn that TEDxMidAtlantic speaker Sam Berns passed away Friday night at age 17. Sam had progeria, a rare rapid aging disease that affects approximately one out of four to eight million children.
Above, moments from Sam’s TEDxMidAtlantic talk, in which he shares his advice for living happily, no matter the challenges. Sam’s talk displays his great courage, infectious positivity, and wisdom beyond his years. He will be missed.
So fail. Be bad at things. Be embarrassed. Be afraid. Be vulnerable. Go out on a limb or two or twelve. You will fall, and it will hurt. But the farther you fall, the higher you will rise. The higher you rise, the clearer your future becomes. Failureis a gift, welcome it.
Even in the lofty world of aerospace components, GE’s new 3-D printed jet engine fuel nozzle is a rare bird. Workers build it as a single piece by welding together bits of superalloy dust with lasers. The new nozzle is 25 percent lighter and as much as five times more durable than the current nozzle made from 20 different parts.
But here’s the rub. 3-D printing is so new that engineers have to develop new quality-control methods before jumping into mass production. “We are dealing with a microscopic weld pool that’s moving at hundreds of millimeters per second,” says Todd Rockstroh, a mechanical engineer at GE Aviation. “Every cubic millimeter is a chance for a defect.”
