Ryan Knapp is a senior staff meteorologist and weather observer at the Mount Washington Observatory in White Mountains, New Hampshire. When we talked on the phone, the temperature at the observatory—which is at the mountain's summit— was hovering between -20 and -30 degrees. Most of us experience painfully frigid temperatures like that rarely, if ever, but it's not out of the ordinary for Knapp and the Mount Washington crew. Sitting at 6,267 feet above sea level, the facility has an average low of -4 degrees and a record low of -47 degrees. And that's before you add in the punishing winds which gust to 70 miles per hour and beyond. Brutal.
Google Street View images are filled with cars. That is a simple and pedestrian truth, and one which artificial intelligence researchers have taken advantage of to do something surprising. By analyzing car type, they were able to make predictions about the demographic information of the people in the cities they studied.
At its best, virtual reality is transportative: It will let you scale a simulated cliff face, or come face-to-teeth with a T-rex. You can have those experiences from your living room, but of course, you need a virtual reality headset, and for that, you have two broad categories to choose from—a low-end contraption that uses your smartphone, or a fancy rig that requires a PC.
