<b>ABSTRACT</b><br>
In high-energy scattering processes, we study the proton as it
travels at the speed of light. Due to Lorentz time dilation, the
strong interaction between quarks and gluons slows down
considerably, and the proton appears as a collection of
non-interacting partons. In this talk, I will discuss to what extent
one can use this picture to describe various properties of the
proton, including its spin, and visualize the results of high-energy
scattering experiments at JLab at 6 and 12 GeV and other facilities
worldwide. I will also discuss how to directly calculate the
properties of partons using the large scale numerical simulations of
QCD.<br>
