Italian astronomer and mathematician who was the first to use a telescope to study the stars; demonstrated that different weights descend at the same rate; perfected the refracting telescope that enabled him to make many discoveries (1564-1642)

1612 - Galileo Galilei becomes the first astronomer to observe the planet Neptune, although he mistakenly catalogued it as a fixed star.

The last time a lunar eclipse occurred on the winter solstice, astronomer Galileo Galilei was languishing under house arrest for suggesting the Earth circled the sun.

You have just read a pamphlet entitled the Starry Messenger, by a mathematician at the University of Padua named Galileo Galilei in which the author reports remarkable observations about the heavens.

你已经看过一本名为「星夜的差使」的小册子，这本由帕瓦多大学的数学家伽利略撰述有关天空的卓越发现。

I recall that we discussed scaling and we used - the interesting example of Galileo Galilei — an animal, and the animal has legs.

我记得我们讲过缩放标度，我们用到，伽利略的有趣的例子-，一个动物，它有腿。

And that may have convinced Galileo Galilei that that's the reason why the largest animals are as large as they are.

我想这就是，为什么，伽利略认为动物就，只能是这么大。

This principle was famously demonstrated by Galileo Galilei some 400 years ago when he simultaneously dropped cannon and musket balls, and balls made of gold, silver and wood, from the Tower of Pisa.

这一法则是在大约400年前，由伽利略?伽利雷那个着名的比萨斜塔实验所证明的，当时他在塔顶同时释放球型炮弹和毛瑟枪子弹，以及由金、银、木头制成的小球。
