关于“理论”的一篇中文，请翻译成英文

Question

理论是实践的基础，并且理论贯穿于整个实践之中。理论是人们从实践中总结出来的关于自然界和社会知识的系统概括，又反过来指导实践。
理论是丰富的知识。在市场经济高速发展的今天，每一个人都要掌握丰富的科学知识，才能适应竞争激烈的社会。
诺贝尔从小主要受家庭教师的教育，后又到法国和美国学习理论知识。返回俄国后，他把他学到的理论用到化学研究上，他终于研制成功了炸药。
没有理论作条件，缺少理论的指导，一切实践都是盲目的，甚至是失败。这就是为什么各大高校先有理论课，再设实践课的原因。
因为我们站在许多前辈和巨人的肩膀上，他们提出了那么多经典的理论，为我们作指导，让我们去学习。 只有更好的学习理论知识，才能更好的指导自己的实践，实现自己的目标，完成自己的人生理想。

Mainly affected by the Nobel childhood education tutor, and later to France and the United States to learn the theoretical knowledge. To return to Russia, he learned the theory of his use of chemical research, he finally succeeded in the development of explosives.
There is no theory for the conditions, the lack of theoretical guidance and practice are all blind, and even failure. That is why major colleges and universities first theory course, and then the reasons for the practice lesson.
Because we stand on many of the older generation and the shoulders of giants, they have made so many classic theory, for our guidance, let us to learn. Only a better knowledge of learning theory in order to better guide their practice and realize their goals, the completion of their ideal life.
