In the world of electric cars, there's a chicken-and-egg problem: More people might buy electric vehicles, or EVs, if they were confident there would always be a charger nearby. And businesses might install more chargers if there were more EVs on the road.

The Chevrolet Bolt EV, which is now hitting the market, could be the first of a new wave of game-changing electric vehicles.

Its longer range and lower price could attract new buyers to the electric car market, but there's uncertainty over whether federal tax incentives will continue and whether California will be allowed to keep tougher emissions rules under President Trump.

Next month, there's a world chess championship match in New York City, and the two competitors, the assembled grandmasters, the budding chess prodigies, the older chess fans — everyone paying attention — will know this indisputable fact: A computer could win the match hands down.

They've known as much for almost 20 years — ever since May 11, 1997. On that day, IBM's Deep Blue defeated the great Garry Kasparov who, after an early blunder, resigned in defeat.

Throughout the last academic year, we've followed a group of students who graduated from high school a few years ago in Montgomery County, Md., just outside Washington, D.C.

I was in Luxembourg recently, in advance of the British referendum on leaving the European Union, and received a tour, a history lesson and practically a sermon on the merits of the European Union by Heinz-Hermann Elting.

Elting is a German-born resident of Luxembourg City. He's retired now and rides his bicycle around the city when he isn't caring for his sheep — that's singular "sheep." He used to work for the European Parliament, a movable legislative feast that spends a part of the year in Luxembourg.
