The 29th Latvian Open
PHYSICS OLYMPIAD
Friendship match in Israel
April 18, 2004
In order to strengthen the ties established by the first Friendship match,
the organizing committee decided to publish
some of the most elegant solutions presented by the Israeli participants.
Criteria for the selection were quite subjective, therefore this collection
does not pretend to any completeness.
We also hope to complement this page by the best solutions from the Latvian students shortly.
Laconic and correct solution to the problem No. 9 by Ilya Greenglaz:
Problem No. 9 by Ilya Greenglaz.
The problem No. 2 turned out to be extremely hard
to both Latvian and Israeli participants.
Here is one of the rare correct solutions due to Veronika Ulychny:
Problem No. 2 by Veronika Ulychny.
The Problem No. 3 (Floating Bell) can be solved by firing cannons (that is,
by direct integration of the hydrostatic force).
There are much simpler ways, however.
Madars Virza (Valmiera) and Asaf Harel
(Tel Aviv) have presented a surprising two-line solution thus earning more
than 2 points for this problem. Another elegant way is demonstrated in the Veronika's paper:
Problem No. 3 by Veronika Ulychny.
The problem No. 8 does not require integration as well, as demonstrated by
Yair Carmon:
Problem No. 8 by Yair Carmon.
The Problem No. 1 (experiment "fried droplets") turned out to be the hardest for the Israeli team.
Here is one of the best explanations for the ``hot'' surface case by Avi Aminov:
Problem No. 1 by Avi Aminov.
In contrast, Problem No. 4 has been relatively easy:
Problem No. 4 by Vasili Galka.
