Author in 2000

This is me now, after 20 years. Yes, now I'm  octogenary  and I retired a long time ago from professor activity in front of my students. But although my body sometimes gets tired, the mind still remains active and clear. 

More of my scientific and professional activity you can see in original version of the book, in Romanian (https://cursmecanica.blogspot.com/). 

Untill now, this link has been accessed over 15,300 times, most from the countries where the Romanian language is spoken or where are Romanian students  or graduates preparing a master's degree. 

I am now convinced that this book would be useful also to other users if it were presented in another language, other than Romanian, for example in English. 

And one day I said "WHY NOT ?". I decided to translate the book in English. But it's a problem - I'm not an English speaker and I have low  knowledge in this language. The solving came from Google Translator with which I did the translation in a few months. 

I am also sure that the English version contains grammatical errors or inappropriate expressions; there were difficulties in the equivalence of some technical terms. I will be grateful to the readers who will report to me these errors to make the necessary corrections.
