About the header image.

I’ve designed the main header image  using a number of programs and placing or blending six different smaller pictures three by three in two columns on top of a primary big background  picture consisting of multiple mixed colors  .

The first picture (top left ) is a galaxy and represents astronomy .It was resized and customized using  Photoshop.

The second picture (top center) was made using Autocad and Photoshop.The last curve to the right is a three-dimensional sinc function . A sinc function is of the form: sinc(x) = sin(x)/x.

The third picture ( top right) was made using MathType , Photoshop and Illusstrator.It represents the Laplace operator or Laplacian in cylindrical , spherical and curvilinear coordinates.

These three top pictures represent some of my interests related to exact sciences such as astronomy, 3 D geometry , mathematics and physics.

The first picture (bottom left) is of a book , probably a dictionary or an encyclopedia .It could correspond to knowledge , culture and/or information.

The second picture (center bottom) is an ebook reader , corresponding to modern digital information and knowledge.

Finally the third picture (bottom right) was designed using Photoshop and Illustrator.It consists of words related to education and educational topics , the word ‘education’ being written in four different languages.
