The book by Leonid Vaisberg and Ivan Ustinov “Introduction into minerals separation technology” was published.
There exists the illusory understanding that the politicians rule the world.Always and at all times.
The stone, bronze, iron age.., industrial revolution.
The technologies change the world by determining the social and economic eras, successively alternating them, and sometimes through the revolutions, unfortunately.
These are the general considerations having no relation to this one, in particular.
The book has been just released from the printing-office.
Specially for many and many colleagues, including only our future students!
