New Year, New Era

摘要

For nearly 144 years, Popular Science has arrived at your doorstep, in your mailbox, or on your newsstand just about the middle of each month. Starting with this issue, we'll be doing things a bit differently. Instead of monthly delivery, Popular Science will begin offering bigger, richer magazines every other month. This is, obviously, a big change-like once every 144 years-and it bears some explanation. When making a product, two of the most important questions you can ask are, "How are people using my widget, and have I optimized for that case?" The engineers, entrepreneurs, and designers we cover ask these questions regularly. We thought it only right to ask them ourselves.
