When I was in Seoul last week, I took the subway with my students several times. We noticed a few differences from the subways in Japan. In Seoul, they play interesting music when a train is approaching. Another difference is that the subway cars in Seoul are wider than those in Japan. This may be why so many people walk up and down the cars. People were always trying to walk past us. Were they looking for empty seats, or did they just want to get off at another door? I don’t know, but it doesn’t usually happen in Japan. Most passengers just get on and stay where they are. (by Prof. Douglas Jarrell)

Apple came out with its first iPhone 10 years ago, and it changed the world of cell phones. This year, Apple has three new phones: the iPhone 8, the iPhone 8 plus, and the iPhone X (ten). The iPhone X is the most advanced and the most expensive of the three. One amazing thing about this phone is that it knows who the owner is by their face. It will unlock when you look at the screen. Apple says that it can recognize a person, no matter what the hairstyle. If that is true, then AI is better than me. I cannot recognize some of my own students after they change their hairstyles!
