Usually the term saddle makes us think about the seat in a horse
back or the seat in a bicycle or in a motorcycle.
In horseback riding, the saddle is the seat that horse riders
use to keep themselves firmly sitting upon the horse's back. It
is attached to the horse using a girth and a wide strap. The
wide strap will go around the horse to keep the seat from
moving.
It is most important that the saddle will keep both horse and
rider comfortable to avoid injury to both of them. Saddles may
either be English saddles or Western saddle depending on what
purpose they are used for.
An English Saddle is used for Polo, Racing, Jumping, Show,
Dressage, Park, Show or it can be an All Purpose Saddle. Western
Saddles on the other hand are used for Trail, Endurance,
Pleasure, Barrel and Roping activities. While Sidesaddles,
Australian saddles and Military saddles do not fall into either
category.
Although this is true, as is a saddle is also a meat part of
mutton, lamb, venison or veal that is from both sides of the
animal consisting of its unseparated meat from its rib to its
leg or that it could mean the passage found between the low area
of hills or mountains.
In construction terms, a saddle is a piece of wood that serves
as a decoration covering sections of different materials or
heights.
But as weird as it may seem, the term saddle is also connected
with mathematics. In this field, a saddle point is a point of
one or more valuables (commonly known as function).
Tat is both stationary point (this is a part of calculus that
explains the parallelism of tangent to the x ? axis of the graph
or when the plane tangent is parallel to the surface of the XY
plane.
In the saddle point, the funcion of its single variable is the
point where zero is its first derivative, the second derivative
on this case, changes the sign. To better explain it, in the
example the funtion of y = x3 has the same point as the origin.
The reason that a saddle point is called as such, because in a
function with two or more variables, the two dimensional
topological space (surface) looks like a saddle that is curving
up in one or more directions and also curves down in one or more
direction (kind of like a mountain passage or saddle).
In a contour line, the saddle point is apparent by the contour
that seems to intersect itself. Example, a saddle point can be
recognised in two mountains or hills separated by a high pass.
At the top of this pass, one will be able to see a figure
eight-like contour that forms the saddle.
For two variables with a real function mathematics used the
Hessian matrix to have 2x2 matrix. This is a function that has a
curving down pattern along the x and a curving up pattern along
the y thus creating the saddle point.,
Also, there is what we call the saddle point approximation where
in the steepest descent method is used to approximate integrals.
Saddle points are not only found in mathematics, physics also
have their own saddle points. Between electron in solid and
electrons in liquid, the wet electrons are considered the saddle
point.
