【类型】：科学/记录 【集数】：共1集 【片长】：53分钟 【字幕】：外挂英文 【服务器】：随机 【供源状况&分享时间】：供源全天24小时 【内容简介】： 时间、是一种相对或绝对的概念，早在三十五亿年前人类主宰世界，便开始受到时间的约束。即使你不用时鐘来测量，时间仍照样存在并继续流向未来。 Discovery Channel带领您进入时间的抽象概念，一同体会时间的无所不在与人类演进之间密不可分的关係。生理时鐘存在於植物与动物的细胞中，这种时鐘使生物得以对瞬息万变的环境採取适当的反应、调节作息并生存下来。时鐘的发明让人类能具体地掌握时间，改善生活，如：音乐初学者使用节拍器帮助他们用固定的节奏演奏音乐、航海家靠著精确的时鐘分辨出航向与位置、蒸汽时代的火车利用时鐘发明出统一时区避免误点，以及利用卫星即时更新全球时间及位置资料的GPS全球定位系统等都是。 Time - what is it? St. Augustine wrote, "What, then, is time? If no one asks me, I know. But if I want to explain it to someone, I do not know." Perhaps we should ask: Did time have a beginning? A very old question, indeed. But how can we imagine a world before time began? If we count backwards beyond the clock, beyond the calendar, three and a half billion years, we arrive at our own beginning - the dawn of life on earth. Science has a word for it: biogenesis. The birth of life. With life, nature created a new kind of time; more advanced, more evolved from the time of the physical world. Memory and expectation provided us with a competitive advantage. Memory and expectation gave birth to the concept of a past and a future. Now flash forward three and a half billion years. Humanity rules the earth. Humanity is wrapped tight in ticking time. But time ticks on towards the unknown. In physics, space is represented as three dimensions. Time is represented as the fourth dimension. To describe time, we are often asked to think of objects in motion. For instance, time has been compared to the cable that drives the quaint cable cars of San Francisco. The cable car attaches itself to something that's hidden, something that's to an extent, mysterious. It is moved by a mechanism you don't know and cannot see. It just moves you along - takes you on a ride. At birth, we are clamped to a buried cable, time. And at death, cast loose from its passage. Or are we? The answer lies somewhere in time, yet an understanding of time remains as elusive and mysterious as life itself.
