In physics, a saddle is actually a combination of two parabolas meeting each other at their minima and maxima respectively.

The circus performer utilises the fact of minima of one parabola and keeps his position unaltered. Similar to a pendulum which has minimum potential energy at the vertical position.

When the circus performer jump high, they move at the old velocity .It means that they move at the same velocity with the horse because of inertia. Thus, they fall back but still remain on the saddle
Do you think this solution is completely right or not?

marshal: Dear Members of this form, I am working on DFT. Plz tell me how I can correlate: optical properties, thermoelectric properties, effective mass, and Bader Charge in a single Manuscript, i.e. How these properties belongs to each other? Feb 4, 2016 9:18:27 GMT 1
