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.”
Un giorno in collegio la mia professoressa spiegò la differenza tra il tatto e l’educazione. Un signore, in casa di amici, apre la porta di una stanza da bagno e scopre una donna nuda: si ritira subito, richiude la porta e dice: “Oh, scusi signora”. Questa è educazione. Lo stesso signore, aprendo la stessa porta, scoprendo la stessa donna nuda, dice: “Oh, scusi signore”. Questo è tatto. #BaciRubati
