We have seen one book by Yakov Khurgin previously in the Science for Everyone series named Yes, No Or Maybe . Now we come to another book by him with the title *Did You Say Mathematics?*

The back cover of the book says about the author:

Dr. Yakov Khurgin is professor of mathematics at the Chair of Applied Mathematics at the Gubkin Institute of the Petrolium and Gas Industry. He has written over a hundred scientific papers in pure and applied mathematics and has been particularly productive in the fields of radioengineering, radiophysics, cybernetics, neurophysiology and psychiatry. At the present time, Professor Khurgin heads the laboratory of applied mathematics. He is also a member of the USSR National Committee of Automatic Control.

His extensive knowledge and wide range of activities have helped to make his popular-science book a great success.

And the book itself is described by the author in a section titled* One last word to the reader*:

In the chapters that follow I will attempt to tell the story of mathematics and weave into an integral whole the various discussions I have had with my non-mathematical friends.

This will be a story of mathematics in popular language so that the non-mathematician will see what it is all about. This is not a course in mathematics but merely a series of sketches concerning ideas and

methods. There will be no proofs to carry out and no need for paper and pencil. What I want to do is sketch a picture of the development of mathematics and show what mathematicians are presently engaged

in—to some extent.

This book is true indeed a popular exposition of many concepts in mathematics. The book was translated from the Russian by *George Yankovsky* and was first published by Mir in 1974 and republished in 1984. You can get the book here. Thanks to *gnv64* for this one!

Wow ! Thanks Damitr

Thanks. Please upload some high school level mathematics books like high school mathematics by yankovsy (if you have).

Awesome. Thanks!!

I’ve tryied 2 of those passwords and none of them work, qhat could it be?

@eric I have updated the password ,please check and let me know it works.

what is the current password? can somebody tell me, please??
