From the angle of hitting the ball to the power you force onto it, volleyball is full of many mathematical points it is seen as a classic sport by many but to those few individuals who look into volleyball with more concentration, the beauty of maths is seen clearly before their eyes

Windmills work with air. Air makes the windmill spin and they produce electrical energy. By using windmills we can increase the use of fuel.

Without Geometry, dancers would not be able to be synchronized and create shapes. Besides Geometry, everything in dancing has to do with patterns. Dancers memorize patterns in the steps in their dances. The rythm in music usually consist of patterns in the form of beats.

Whether flying a small model rocket or launching a giant cargo rocket to Mars, the principles of how rockets work are exactly the same. Understanding and applying these principles means mission success.

In the early days of rocketry, the flight of a fire arrow or other rocket device was largely a matter of chance. It might fly; it might skitter about, shooting sparks and smoke; or it might explode. Through centuries of trial and error, rockets became more reliable. However, real advancements in rocketry depended upon a scientific and mathematical understanding of motion. That came in the seventeenth century with the works of scientists such as Galileo and Isaac Newton.

Galileo conducted a wide range of experiments involving motion. Through studies of inclined planes, Galileo concluded that moving objects did not need the continuous application of force (in the absence of friction and drag) to keep moving. Galileo discovered the principle of inertia, that all matter, because of its mass, resists changes in motion. The more mass, the more resistance.

Isaac Newton, born the year Galileo died, advanced Galileo’s discoveries and those of others by proposing three basic laws of motion. These laws are the foundation of all rocket science. Understand the laws and you know just about everything you need to build successful rockets. Apply the laws and you become a “rocket scientist.

Starting off strong with the spike, a powerful and crucial point in a volleyball game. If you take a look at this so-called "simple" move, a fascinating amount of calculations appears beforehand. First of all, the quick thinking mind must decide which angle to jump in and which angle to spike to. If there is a block ahead, you need to angle yourself midair to change and turn to spike away from the block.

In the situation of a block ahead, a player may spike extremely hard to break through the hands or to bounce off he hands to the outside of the court, giving you the point

The volleyball net is the most simple example of the art in volleyball, following up he court and its markings.

A volleyball net is volleyball nets are the primary obstacle and separating element between the two teams in a game of volleyballVolleyball nets stretch out to the entire width of the court, which is 9 m and are held high and strong by outer poles typically set 3’ from the court. The center height of a volleyball net is different for men’s and women’s volleyball. Men’s nets are at a height of around 2.43 m and women’s at 2.24 m. The dimensions of the playing court are often identified on the net top by two antenna extending 80 cm above the net Volleyball nets have a surface height of 1 m from top to bottom and are constructed with a polypropylene or nylon netting with a mesh size of 10 cm and are capped with stiff headbands along the perimeters..
