  This article is a slightly expanded version of the talk I delivered at the
Special Plenary Session of the 46-th Annual Meeting of the Israel Physical
Society (Technion, Haifa, May 11, 2000) dedicated to Misha Marinov. In the
first part I briefly discuss quantum tunneling, a topic which Misha cherished
and to which he was repeatedly returning through his career. My task was to
show that Misha's work had been deeply woven in the fabric of today's theory.
The second part is an attempt to highlight one of many facets of Misha's human
portrait. In the 1980's, being a refusenik in Moscow, he volunteered to teach
physics under unusual circumstances. I present recollections of people who were
involved in this activity.
