Hello,
I know nothing about Jquery  but am going to take an online course.
But right now I have an issue where 2 jquery scripts don't work together.
I can change the 1st library to 1.9 and it works but not with the 2nd call for it and I don't know how to solve it.
How can this section of code be written so both call for 1.9 and work together?

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
  <script>window.jQuery || document.write('<script src="js/libs/jquery-1.3.0.min.js">\x3C/script>')</script>
 
  <!-- FlexSlider -->
  <script defer src="jquery.flexslider.js"></script>
 
  <script type="text/javascript">
    $(function(){
      SyntaxHighlighter.all();
    });
    $(window).load(function(){
      $('.flexslider').flexslider({
        animation: "slide",
        start: function(slider){
          $('body').removeClass('loading');
        }
      });
    });
  </script>

<script>
Modernizr.load([
{
    load: [ 
        'http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js',
        '_scripts/klass.min.js',
        '_scripts/code.photoswipe.jquery-3.0.5.js',
        '_scripts/desolve.js' 
        ],
      complete: function() {
          var myPhotoSwipe = $("#photoGallery a").photoSwipe({});
      }
    },
    {
    // test for media query support, if not load respond.js
    test : Modernizr.mq('only all'),
    // If not, load the respond.js file
    nope : '/js/respond.js'
    },
    {
        //test to see if it's a bigger screen, if so load lettering
        test : Modernizr.mq('only all and (min-width: 481px)'),
           // load lettering.js if it is a larger screen
            yep : { 'bigscreen' : '_scripts/jquery.lettering-0.6.min.js' },
        // after loading lettering, target the galleryTitle with the lettering library
            callback: function (url, result, key) {
                   // if lettering was the file loaded, execute this script
                 if (key == 'bigscreen') {
                       $(document).ready(function() {
                    //apply the lettering function
                      $(".galleryTitle").lettering();
                });
             }
    }
}
]);
</script>

Thank you for taking the time to look and hopefully someone has the answer.
