They may not, according to Cartledge, have had a word for wheelbarrow - but they certainly invented the amazing Antikythera Mechanism , object of much recent research and excitement from classicists and scientists alike.

按照卡特里奇的说法，希腊人可能连手推车都不知道是啥；不过正是他们发明了安提凯希拉天体仪，一个最近令古典学者和科学家大感兴趣并纷纷研究的奇妙装置。

In fact, 21st century astronomers would classify it as a Planetary Nebula, but it's not a planet either, even though it may appear round and planet-like in a small telescope.

事实上，21世纪的天文学家将该天体归类为行星状星云，但是它也不是一颗行星，尽管通过小型望远镜看，它的外观可能呈圆形、类行星状。

In the light of the drawbacks of the conventional porkchop plots method that needs a lot of computation time with low computation efficiency, a search approach for optimal launch window for exploring small celestial body was proposed based on the genetic algorithm.
