用英语简述对机械专业的看法 ，要求字数150左右，麻烦写的好的尽快回复，谢谢

Mechanics is an industry so ubiquitous that is nearly impossible to be summarized in several words yet so important to our civilization that is manifested in every single area of human endeavor. It is mechanics that makes the world we are living in so convenient and so efficient as it is now. From those simple-structured fix-gear bicycles to those cutting-edge F-22 Raptor stealth fighters, mechanics serves as the foundation of human labor. It is also an industry that has a splendid history that can be dated back to those ancient cultures, but in the same time it is so promising that is still essential to the world today and will be indispensible within the predictable future. Despite its chronic and systematic development, it is still believed that mechanics has a long way to go, such as the improvement of precision on manufacturing, the combination of mechanical design and computational technologies making designing more efficient and more labor saving, etc. Anyway, mechanics has played, is playing, and will play a major role in the process of modernization of the society.全是自己写的，这是我当年申请出国时自述里面用到的句子的简化，改了一点点。
译文：机械行业应用如此广泛，以至于我们很难用三言两语将其概括，但是机械行业也如此重要以至于它在人类文明的每个领域都有体现。机械让我们生活的世界更加便捷。从是最先进的F-22隐形战斗机到结构简单的死飞自行车，机械俨然称为了人类劳动生产的基础。机械行业有着悠久的历史，可以追溯到诸多古代文明，同时又拥有如此光明的未来，以至于在可见的将来他都是不可或缺的。尽管经历了长期的系统化的发展，机械行业已经日趋健全，但依旧有很大的发展空间，比如不断提高制造加工的精度，将机械设计与计算科学相结合从而提高效率减少劳动等等。总之，机械曾经，如今，将来都在社会进程当中扮演着主要角色。
