Determination is a positive emotional feeling that involves persevering towards a difficult goal in spite of obstacles. Determination occurs prior to goal attainment and serves to motivate behavior that will help achieve one's goal. Empirical research suggests that people consider determination to be an emotion; in other words, determination is not just a cognitive state, but rather an affective state. In the psychology literature, researchers have studied determination under other terms, including challenge and anticipatory enthusiasm; this may explain one reason for the relative lack of research on determination compared to other positive emotions.In the field of psychology, emotion research is heavily focused on negative emotions and the action tendencies that they encourage. However, recent work in positive psychology incorporates the study of determination as a positive emotion that pushes individuals toward action and results in important outcomes such as perseverance and determination take success.
The word determination comes from the Latin word dēterminatiō, meaning "limit" or "determination, end result." It is derived from the verb dētermināre, meaning "confine; designate," with the abstract noun suffix -tiō. The meaning shifted from "end result, decision" to its present meaning.

Hi,
When two particles collide in the centre of mass frame, they interact and then scatter. Am I right in thinking that the resultant scattering angles are completely arbitrary? If so is this a case of an effect with no cause? Just hoping someone can clear this up for me.
