Popular Science Question Bee
February 1939 Popular Science

February 1939 Popular Science

February 1939 Popular Science Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Popular Science, published 1872-2021. All copyrights hereby acknowledged.

Here is a fun "Question Bee" to test your scientific knowledge. It appeared in a 1939 issue of Popular Science magazine, but it does not require you to be aware of contemporaneous information. Topics include electricity, music, astronomy, automobiles, paint, tools, conservation, physics, and even chewing gum. There are 20 questions. I scored 95%, having incorrectly guessed at question #11, having to do with cave dwellers. To be honest, I also guessed at question #2, but managed to get it right. Go ahead and give it your best shot. It's really a pretty good mix of questions.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
