GOD and Mathematics

 So says one of us : Daniel ONOFREI


Today I will publish a copy of an old magazine. I mentioned this number somewhere before...

Almost every article has something to comment on... We'll put it at the end, maybe they'll be the source of future posts.


Nostalgic comments


                1.  First, pages 71-73, the Problems given at the Admissions Competition at the University of Timisoara, when I also applied. The exact order of the days was 1. Algebra, 2. Mathematical Analysis 3. Geometry and Trigonometry. I got an average of 9.85...

                2.  Pages 63-66, Problems from the Local Phase of the Mathematical Olympiad. I was in Grade 12. I seem to remember Problem 3921.

                3.  On Cover 2, I was informed that the magazine is no longer being delivered individually

                4. Two trigonometric identities without variables, 3831 (page 51) and 3928 (page 67) -- at points 10 and 11 on the Page here.

                5.  Pages 8-11, a nice article by Dorin ANDRICA, about sequences that have an intervening limit point, e.g.  $(\sin n)_{n\in\mathbb{N}}$.

                 6.  Now Friends and EnemiesAurel DOBOȘAN (an article on page 17), the one who praised me at the National Phase of the 1977 Mathematics Olympiad, for solving a Geometry problem using the Reciprocal Bisector Theorem.

                Titu ANDREESCU, with an article that impressed me this time (pages 12-14) generalizing two IMO Problems from 1979

                Cornel BĂLTEANU, who "blowed" my girlfriend DIANA URECHESCU (sister of my high school classmate, GABRIELA Urechescu) has an article on page 15

                7. A Magazine COMPETITION was also inaugurated (pag 81), in which I participated "for fun" with my college colleague Costică BUȘE...

                8.  From the Proposed Problems (pages 35-62) I see that I solved 3810 (I posted it somewhere here and on the Blog), here are 3895 and 3899, I lost them somewhere among my notebooks from my youth.
