Popular Science, or PopSci, is a monthly magazine that covers the latest developments in science and technology, including gadgets, robotics, space exploration, and environmental issues. It has been in publication since 1872.
The Popular Science logo was most likely created using FF Din Pro Black, with minor adjustments made to the letter "C." This typeface was created by Albert-Jan Pool, a Dutch designer. The font is commercially available, and additional information can be found here.
