    Extractions: Pascal's Triangle Pascal's triangle is a number triangle with numbers arranged in staggered rows such that where is a binomial coefficient , the triangle is (Sloane's Pascal's formula shows that each subsequent row is obtained by adding the two entries diagonally above, The plot above shows the binary representations for the first 255 (top figure) and 511 (bottom figure) terms of a flattened Pascal's triangle. The first number after the 1 in each row divides all other numbers in that row iff it is a prime The sums of the number of odd entries in the first rows of Pascal's triangle for , 1, ... are 0, 1, 3, 5, 9, 11, 15, 19, 27, 29, 33, 37, 45, 49, ... (Sloane's ). It is then true that (Harborth 1976, Le Lionnais 1983), with equality for a power of 2, and the power of given by the constant (Sloane's ). The sequence of cumulative counts of odd entries has some amazing properties, and the minimum possible value (Sloane's ) is known as the Stolarsky-Harborth constant Pascal's triangle contains the figurate numbers along its diagonals, as can be seen from the identity

    a^2+((a^21)/2)^2+((((a^2+1)/2)^2-1)/2)^2 = ((((a^2+1)/2)^2+1)/2)^2 Reference C. Stanley Ogilvy, Tomorrow's Math Unsolved Problems for the Amateur.  
    http://everything2.com/title/Rational box
    
    Extractions: To date, no such rational boxes are known to exist . It is an open question as to whether any exist at all. As a side note, it is trivial ly easy to come up with an integer main diagonal. Let a be an odd number. Then a^2 + ((a^2-1)/2)^2 is the square of (a^2+1)/2, which is odd. Then (((a^2+1)/2)^2-1)/2 and (((a^2+1)/2)^2+1)/2 are the other two numbers of a pythagorean triple . So the length of the diagonal would be (((a^2+1)/2)^2+1)/2 (if it were formed in this way), and the equation would look like:

What I often find are complicated math unsolved problems which require quite deep math knowledge that is not really taught at my gymnasium. Thanks for help... Mu naught Jun4-10, 02:44 PM what makes you think those two questions are easy? Atran Jun4-10, 02:48 PM By 'easy' I mean that it's easy to understand the question. For instance, I know what a perfect number is, so "is there any odd perfect number" question is understood by me.

Not unique A ndrew Ostergaard shared with me on March 6 a variational problem which he thinks has first appeared as an interview problem. The problem can be traced to [5] (1980). What is the shortest curve in the plane starting at the origin, which has a convex hull containing the unit disc? The problem can be embedded into a little story: you find yourself blindfolded in a forest, in distance 1 to a street. This straight line and located in an unknown direction to you. How do you walk best to reach the street for sure?

Moreover, there is always a prime between and where (Iwaniec and Pintz 1984; Hardy and Wright 1979, p. 415). The smallest primes between and for , 2, ..., are 2, 5, 11, 17, 29, 37, 53, 67, 83, ...
