The mind takes it in and starts working on it for you. Since they are subjects that take analytical thinking you would naturally take more time for it on the analytical stage. PhotoReading will slice the time required if you allow yourself to superread and dip a few activation passes before you start the analytical reading stage.
What slows people down with the activation of text like this is they try to get the analytical reading done first without having an understanding of the whole subject in general before going into the detail of the specific parts.
