Editor's note

On this day in 1998 – 20 years ago in human terms, but a geologic age in internet time – Google was incorporated. Information scientist Gary Marchionini from the University of North Carolina at Chapel Hill looks at how the company transformed the online-search business, and examines the challenges – both internal and external – the company will face over the next 20 years.

How many school shootings happen in the U.S. in a single year? Counts wildly disagree, writes Pennsylvania State University’s Lacey Wallace. One Department of Education report said there were 240 during a recent school year, while an independent investigation could only confirm 11. Wallace explains why the data on such an important topic is so muddled.

Fifty years ago, on an episode of “Star Trek,” actors William Shatner and Nichelle Nichols locked lips for television’s first interracial kiss. Arizona State’s Matthew Delmont recounts how Nichols would go on to become known for far more than a kiss, becoming a forceful advocate for inclusion in Hollywood, in science and in space. And want hear the kiss and listen to Delmont talking about its impact on TV viewers? Then subscribe to our new podcast about 1968, Heat and Light, here.

The Department of Education says there were 240 school shootings during a recent school year. Another database only counts 29. How could the numbers be so different -- and who is right?
