Disassembling Apple's diminutive inch-cube iPhone charger reveals a technologically advanced flyback switching power supply that goes beyond the typical charger. It simply takes AC input (anything between 100 and 240 volts) and produce 5 watts of smooth 5 volt power, but the circuit to do this is surprisingly complex and innovative.

Key stakeholders in a decision need to decide effectively and commit to their choices. To borrow a phrase from Bill Walsh, a leader who coached the 49ers to 3 Super Bowls, strong leaders need to "commit, explode, recover," which means committing to a plan of attack, executing it, and then reacting to the results.  A team crippled with indecisiveness will just cause individual efforts to flounder.

"I want you to go to Target. I want you to go to the Lego aisles and just go look at the toys, for a minute. And think about it. Think about young women who don’t go into science and engineering, even now, who struggle with math for reasons that have nothing to do with their innate intelligence, potential, ability."

"I want you to think about how many female engineers you know."

"And I want you to get pissed."
