Solid Geometry

Geometry is one branch of mathematics. It is concerned with properties of space that are related with distance, shape, size, and relative position of figures. There are many concepts we used in our normal life like line, plane, angle, curve, surface and  dimension. For example in golf swing, we always talk about the swing plane — that means our club’s moving trajectory is in one plane during the whole swing, but in fact nobody’s swing is in one flat plane.

In geometry, the Pythagorean theorem is a fundamental relation in Euclidean geometry among the three sides of a right triangle.The Pythagorean theorem is applied in many scientific areas, like mechanics & civil engineering. For example, for designing a crane machine, we have to calculate the forces in the pulling ropes and truss if hanging up  5000lbs of weight. It is the same for golf swing: we can get the pulling force along the arms & club direction if we know the vertical force and the horizontal force.  Then we can calculate the club head speed according to Newton’s second law.

Geometry has many applications in architecture. In fact, it has been said that geometry lies at the core of structural design.  Even though our body structure is not exactly the shape of lines and angles like the building and the bridge, the geometry concepts of the symmetry, similarity and the topology are still applied on the research of the body posture and functions.

Forces and geometry in structure

All structures experience forces at all times. We can’t see a force, but we can deduce its existence by observing its effect. Sometimes the effects of those forces are not apparent until time has passed. That is why it is crucial to design a structure carefully, build it skillfully, maintain it periodically, and monitor it diligently throughout its useful life.

Understanding the relationship of the forces, geometry and structure helps us to maintain a better body posture for different actions, correct some parts which may hurt your body posture, and take more centripetal force. We all know body structure involves health in normal life: like standing and bending posture; and body structure is crucial for all sports: weight lifting, baseball pitching, tennis serve……

For golf swing, to set up powerful body posture is the foundation of the whole swing, because the golf swing consists of the coherent actions of the whole symmetrical body structure which is built by skeletons and muscles.
