<b>ABSTRACT</b>
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.
