At 7, Clovis Hung was bored with second grade. "I wanted more of a challenge," he said. In 2019, his mother, Song Choi, pulled him out of second grade and began homeschooling him. A year later, when he was 9, he also enrolled in Fullerton College. "My husband and two daughters said I was crazy," said Choi, who's worked as a tutor for more than 20 years.

Our current street maps aren't much good for helping driverless cars get around. Although we've mapped most roads, they get updated only every couple of years. And these maps don't log any roadside infrastructure such as road signs, driveways, and lane markings. Without this extra layer of information, it will be much harder to get autonomous cars to navigate our cities safely. Robotic deliveries, too, will eventually require precise details of road surfaces, sidewalks, and obstacles.

Far from the packed arenas and showy lights of the campaign trail, the education of Donald Trump has quietly begun. The unlikely Republican presidential candidate who rose to popularity as a political outsider is now preparing for a general election battle against one of the most experienced policy professionals ever to run for president, presuming Hillary Clinton becomes the Democratic nominee. So as Trump's team begins to ready the candidate for the fall debates and drafts a series of speeches, including one on the U.S. economy, the New York businessman with no elected experience is cramming to get up to speed, consulting experts, asking questions and refining his ideas in anticipation of certain assault by Democrats. The crash courses in foreign and domestic policy are a rite of passage for virtually every presidential candidate. But they carry even greater importance for Trump, who has mocked the Washington establishment as overcomplicating problems and won over many voters with simple ideas that often lack details: build a wall to stop illegal immigration, defeat Islamic State, bring back jobs, make America great again.
