I hope everyone is enjoying their Summer Break. Here at the Preschool, we're undergoing the long-threatened redesign, which involves more than just a layout change. There will still be trivia (I've been saving some up), but I've got something planned for after Independence Day weekend. If you're not a mathematician, you probably won't find the first series interesting. Or maybe you will; it's graph theory, which means there might be pictures. Happy weekend!
