Abstract :
Our teacher, colleague and friend Professor B. Z. Katsenelenbaum approaches his next anniversary. For the last ten years he has been living in Israel where the destiny and circumstances have brought his. It is amazing that being in fact physically isolated from the scientific community, he works especially intensively. For this time he has published three books and prepared the fourth one. His articles regularly appear in the scientific journals. During the recent Israel-Lebanon war, he worked in his apartment (distanced 30 km from the border), when the rockets flew over and some of them exploded in the square in the front of his house. With the humor inherent to him, he asserted: they will not hit.
