Elon Musk: This simple question can help fix what’s wrong with the U.S. education system
Elon Musk, the billionaire CEO of Tesla and SpaceX, has a problem with the way kids are being taught in the U.S. today. And he says there's a simple question that can help: "Why?"

"There are definitely some good schools out there," Musk says, keynoting this year's annual International Space Station Research and Development Conference. However, he says, "teachers do not explain why kids are being taught a subject."

"The why of things is extremely important because our brain has evolved to discard information that it thinks has no relevance," Musk says.

He calls out two main issues: asking students to memorize information or learn formulas without explaining why that's important.
