And I was struck recently when I came across a passage of Johannes Kepler.

最近我很喜欢无意中看到的一段约翰内斯·开普勒的文章。

In the 17th century, Johannes Kepler theorized cosmic musical harmonies to explain the nature of planetary orbits.

在17世纪，约翰尼斯·开普勒 将宇宙周期理论化来解释行星轨道的本质。

And then along came Tycho Brahe and Johannes Kepler, who modified that system, making it even better.

之后，布拉赫可开普勒修改了日心说体系，使之更完善。

And that's what Tycho Brahe and his buddy, or his assistant, really, Johannes Kepler did back in the 1600s.

这就是第谷·布拉赫和他的伙伴，确切的说是他的助手，约翰尼斯·开普勒在17世纪所做的。

Roughly 400 years ago, the astronomer Johannes Kepler realized that there can be other shapes of orbits as well.

大约400年前，天文学家约翰尼斯·开普勒意识到，可能还有其他形状的轨道。

It is believed to also be the largest explosion observed in our galaxy since the 1604 Supernova that was observed by Johannes Kepler.

它也被认为是自 1604 年约翰尼斯·开普勒观测到超新星以来，在我们银河系观测到的最大的爆炸。

In 1609, Johannes Kepler confirmed that the planets, including our own, go around the sun, not in a perfect circle but in an elliptical orbit.

1609 年，约翰内斯·开普勒证实，包括我们在内的行星围绕太阳运行的轨道不是一个完美的圆形，而是一个椭圆形的轨道。

Think about the solar system: back in the 1600s, Johannes Kepler figured out that the farther a planet is from the Sun, the slower it orbits.

早在17世纪，约翰内斯·开普勒就发现行星离太阳越远，其运行速度就越慢。

About 50 years earlier, an astronomer named Johannes Kepler had come up with three laws that described the way orbits worked.

大约 50 年前，一位名叫约翰内斯·开普勒的天文学家提出了描述轨道运行方式的三项定律。

In the 17th century, Johannes Kepler and Isaac Newton laid the mathematical groundwork of planetary orbits, and that in turn made it possible, in theory, to get the distances to the planets.

在17世纪，约翰内斯·开普勒和艾萨克·牛顿为行星公转轨道的研究奠定了数学基础，这反过来又使得从理论上得到行星的距离成为可能。

The equation of time, introduced by Ptolemy and later refined based on the work of Johannes Kepler, converts between apparent solar time and the mean time we've all come to rely on.

“均时差”概念，由托勒密发明后来由约翰尼斯·开普勒进行的改良，包含了太阳时间和平均时间的差距，是我们现在主要使用的时间概念。

A lot of people have heard of an astronomer called Johannes Kepler and how he proved that planetary orbits are elliptical and that the sun is not at the center of the orbit.

很多人听说过天文学家约翰内斯·开普勒以及他如何证明行星轨道是椭圆的，以及太阳不是轨道的中心。

During the Renaissance, the great minds of Nicolaus Copernicus, Johannes Kepler and Galileo Galilei demonstrated the power of scientific study and discovery.

文艺复兴时期，尼古拉・哥白尼、约翰尼斯・开普勒和伽利略・伽利雷这些伟人向我们展示了科学研究和发现的力量。

The investigation of astronomy soon led  to advances in physics. For example, German astronomer Johannes Kepler attempted an  explanation of planetary orbits around the sun.

天文学的研究很快导致了物理学的进步。 例如，德国天文学家约翰内斯·开普勒试图解释行星绕太阳运行的轨道。

But in the early 1600s, the German astronomer Johannes Kepler presented the results of comprehensive observations which showed that the planets move in elliptical – or oval – orbits with the sun at one focus.

但在 1600 年代初期，德国天文学家约翰内斯·开普勒 (Johannes Kepler) 提出了综合观测的结果，该结果表明行星在椭圆形或椭圆形轨道上运行，太阳在一个焦点上。

The seventeenth century witnessed the emergence of whole new fields of scientific inquiry across Europe after the groundwork had been laid down by continental scientists like Copernicus, Galileo, Tycho Brahe and Johannes Kepler in the sixteenth century.

在哥白尼、伽利略、第谷·布拉赫和约翰尼斯·开普勒等大陆科学家在 16 世纪奠定了基础之后，17 世纪见证了整个欧洲全新的科学探究领域的出现。
