The Mason Williams Reading Matter (Used Paperback) - Mason Williams

Mr Williams book answers the question "What is Acrostic". This begs the question of "What is acoustic?" The answer of course is "42" The resistivity of the air in 1969 was 42. But this has changed. The units for measuring the resistivity have changed so the resistivity is no longer 42. See the Philip Morse book on acoustics, or the one by Kinsler.

Condition: Used Book in Acceptable Condition. The book has some discoloration on cover and a few tears in edges of cover.
