走进海洋，随手捞起的，可能是数十滴水，但海洋是那么的‘’海纳百川‘’，容纳了许多河流的水源，多得不可数。。
牛顿在其科学研究中，发现了万有引力，提倡了Calculus 数学微积分（或微积分学），光学等等。。
但他始终感慨的说：“我们所知的只是沧海一粟，我们未知的却是汪洋大海。”

Standing on the beach, picking up a grain of sand, there's an endless expanse of sand beneath your feet.
Walking into the ocean, you might scoop up only a few dozen drops of water, but the ocean is so vast, encompassing countless rivers and streams.
Newton, in his scientific research, discovered universal gravitation, advocated for Calculus, optics, and more.
