Problematical Recreations 4
 

While browsing through my bookcase, I discovered a small booklet of this name. It was published "Courtesy of Litton Industries, Beverly Hills, California".
Unfortunately, it has no date. But, I suspect that it came from the late 1950's or the 1960's. If anyone has also seen this, any of the others in the series, or the original "weekly series" ( which I suspect was an internal employee newsletter ), I would appreciate whatever you can add to the history.

The preface page reads, in part,

Like virtue, a good puzzle is its own reward. The 33 rewarding challenges that follow first appeared in our weekly series and were kindly contributed by our mathematically minded readers.

I propose to post each of them, separated by a day or so. I hope that you will also enjoy them as I did.

by definition, a good pun isn't.

Google is a great resource:

"Reader John R. Aker recently sent me Volume 3 of Problematical Recreations, the famous series of problems compiled by Angela Dunn and published by Litton Industries in advertisements during the early 1960s."

I do wish that I could find all of the series and replay them in this forum.

You can buy them on amazon

I would like to thank you Wacky for presenting the 33 challenge problems to us.

Besides the labour taken by posting them they occupied hours of recreation
and study and references to my many books and in short they enlightened me every single day.

Personally they also enabled me to engage in a search of the many books I have in my library some of which I had bought but never opened before.

For Instance H.E. Dudeney's 'Amusements in mathematics! I had written off as old and outdated puzzles and many others as they were mostly written pre computer era. Today I am using them to compile my problems and they are really terrific as the oldies took the trouble to give shortcut methods and solutions, the best they could find.

Once again, Thanks!
