    putchar('\n'); 
    putchar(scientists[0][0]);
    
    putchar('\n'); 
    
    puts(*(p + 1));

    putchar(**(p + 1));
    putchar('\n'); 
    putchar(scientists[1][0]);
    
    putchar('\n');
    
    putchar(*(*(p + 2)));
    putchar('\n');
    putchar(scientists[2][0]);
    
    putchar('\n');
    int i = 3, j = 6;
    putchar(*(*(p + i) + j));
