Personal Sound Amplifiers (PSA)

Feel free to share this short essay with others.
Comments will be appreciated.

Ludwik Kowalski, a retired nuclear physicist (see Wikipedia), the author of �Diary of a Former Communist,� at:

http://csam.montclair.edu/~kowalski/life/intro.html

It is a testimony based on a diary kept between 1946 and 2004 (in the USSR, Poland, France and the USA). Why is this ON-LINE book free? Because writing it was a moral obligation to my parents, and to other victims of Stalinism.
