APPENDIX TO THE STATUTES OF THE
INTERNATIONAL PHYSICS OLYMPIADS

THE SYLLABUS

 

GENERAL

Adopted in:
Portoroz, Yugoslavia, June 1985
Modified in:
Warsaw, Poland, July 1989
Havana, Cuba, July 1991
  1. The extensive use of the calculus (differentiation and integration) and the use of complex numbers or solving differential equations should not be required to solve the theoretical and practical problems.

     

  2. Questions may contain concepts and phenomena not contained in the Syllabus but sufficient information must be given in the questions so that candidates without previous knowledge of these topics would not be at a disadvantage.

     

  3. Sophisticated practical equipment likely to be unfamiliar to the candidates should not dominate a problem. If such devices are used then careful instructions must be given to the candidates.

     

  4. The original texts of the problems have to be set in the SI units.
