本来是想提供一个认识，理解GOLF挥杆的方法。没想到却与文化习俗站到了对立面。

当人人都认为太阳围绕这地球转的时候，人人都自信地认为地球是宇宙的中心的时候，哥白尼，布鲁诺的思想自然是“反动”。

千年的历史使国人习惯了“只可意寓不可言传”的文化传承模式，加上急功近利的处事态度，科学这个舶来品就显得那么格格不入。

对我的博客提出批评的人的逻辑无非以下这些：

1.你凭什么说你是对的，哪位名人，媒体说你是对的？（不用自己脑子分析的人。）

2.那么多高手都不学，不懂物理，因此物理知识对GOLF不是必须的。（知其所以然不是必须的）

3.学物理，还高等物理？！学武术要的是诀窍，秘籍，苦练（受武侠小说之毒很深，）

4.你拿物理忽悠GOLF必有所图，我来揭穿你！（愤青或者过度自信的中年人）

5.谁用了你的方法取得PGA冠军了?(把我当成卖药的了)

6.我听不懂，没人能懂，你是在忽悠（从来不爱学习已经成为习惯了）

所以那些抱怨我删除了评论的人不必生气，要是批评应该从上述各个角度去说，我都总结了。

科学思想从一开始就与传统对立，只有打破传统才能发展。

门捷列夫的周期表抓住了元素的规律进而深入认识了物质；我希望对纷繁的挥杆特征找到模型的内在规律，对不同身高，柔韧，性格的球手提供适合的方法，使学习少走弯路。

MOE NORMAN，BEN HOGAN，JACK NICKLAUSE, TIGER WOODS等杰出球员的挥杆模型差异巨大，所使用的技术原理各不相同。

为什么人们还坚信有标准的挥杆呢？

挥杆平面的平或陡显然在运动过程中杆给手的感觉是不同的，操控的方法也不同。

为什么还要用相同的词（感觉）去描述呢？

将精湛的技术当作艺术来欣赏可以，但是“戏说”科学，只看结果不讲过程就露出浅薄的本质了。

How to power the golf swing - the basic physics

The first concept that a beginner golfer needs to understand with respect to powering a golf swing is the basic concept of how power is applied to the clubshaft. There are two basic methods of causing the clubshaft to move downwards towards the ball during the downswing action.

A golfer can either pull the clubshaft down towards the ball using the left arm/hand or a golfer can push the clubshaft down towards the ball using the right arm/hand.

A golfer who pulls the clubshaft down towards the ball using the left arm/hand is a swinger. A swinger basically holds the club in his left hand and pulls the grip end of the club down towards the ball - as if he is pulling on a rope. This technique is called the rope handle technique. A golfer can simply think of a person who rang church bells in the medieval era, and imagine how they pulled on a rope attached to a church bell - they simply pulled the rope down towards the ground. A golfer who swings a golf club is essentially mimicking that rope-pulling action by pulling the grip end of the golf club down towards the ball with his left arm/hand. The major difference is that he is pulling on a solid linear object - the clubshaft - and the direction of the pull is along the longitudinal axis of the clubshaft. Another major difference is that a golfer allows the clubshaft to acquire a 90 degree angle between the left arm and the clubshaft at the end of the backstroke, before he pulls the grip end of the club down towards the ball. The movement of the left hand arc in space during the downstroke is circular when the left arm is pulled down across the front of the body and the clubshaft is therefore being pulled by a pulling force that is constantly changing direction. How does that constantly changing direction of pull-force affect the movement of the clubshaft during the downswing?

我认为这种分类方法是不准确的！球手是双手握杆啊。
