In 2007, Nike introduced a driver called the Sumo. It was immediately identifiable because of its square head shape as well as the signature sound it made when impacting the ball. The noise in question was a loud “clank” that many players found annoying. “The Sumo had a very strong frequency content around 2,000-3,000 hertz,” says Daniel A. Russell, a professor of acoustics at Pennsylvania State University's College of Engineering. “That's right where the human ear is most responsive to sound.”
On a recent Sunday morning, 93-year-old Bernie Fowler laced up his white sneakers and waded into Maryland's Patuxent River, a tributary of the Chesapeake Bay, just as he has done every June for the past 30 years. He was conducting his annual test of water clarity by seeing how deep he could go and still see the tops of his shoes.
Just a few days ago, Microsoft announced an upgrade to its Surface Pro touchscreen computing device (Redmond hates when you call it a “tablet”). You might have missed it because not a whole heck of a lot has changed. The Surface Pro now has the latest 7th-gen Intel processors, extended battery life up to 13.5 hours, and a swanky new keyboard covered in Alcantara, a material that feels a bit like suede, but is made from polyester and polyurethane to make it durable. What has significantly changed, however, is the Microsoft Surface Pen, and that could be a big step forward for Microsoft in its current efforts to court the creative class.
