That's the sign I posted near my classroom door to welcome a group of South Korean visitors today. The city officials were guests of Rio Americano's Civitas program. Their visit coincided with my student teacher's class, so I was free to chat with them. They had great questions and had the foresight to document their visit photographs. My kind of people!
They assured me that my sign was a correct translation of "Welcome to Physics," and I was in no position to argue with them—or with Google Translate. A Korean student (whom I adore) later scolded me for being so formal in my greeting. I gave her the sign and the task of providing a friendlier, more casual greeting for the next time I am visited by a Korean delegation.
If you've never tried the Translate smart phone app, fire it up and try it on this message via its photo analysis feature. Very impressive!
