youdao

Sergio: He invented calculus, the reflecting telescope, color spectrum, and the laws of motion.

塞吉奥：他发明了微积分、反射式望远镜、光谱以及运动定律。

youdao

The way the physics works is you will find some laws of motion in mathematical form, you put in the initial conditions of whatever, you solve the equations, and the answer that comes, you have no choice.

在物理问题中,你可以用数学方法得到运动定律,你代入初始条件,然后解方程,获得答案,你别无选择

That's how he often writes about human behavior, that we obey the same laws of physical attraction as do any other bodies that we might choose to describe. They describe how bodies in motion always and necessarily behave, these laws of nature.

这是他经常说的人类行为，我们遵守同样的物质吸引的法则,其他人也一样,他们描述运动中的身体,经常而且肯定会，体现出自然法。

He expressed for the first time accurate laws of motion, the origins of colours, the existence and effects of gravity, and the fact that the same physical laws hold true throughout the universe.

ECONOMIST: Isaac Newton

These revolutions can be triggered by technological breakthroughs, such as the construction of the first telescope (which overthrew the Aristotelian idea that heavenly bodies are perfect and unchanging) and by conceptual breakthroughs such as the invention of calculus (which allowed the laws of motion to be formulated).

ECONOMIST: The scientific method

Kepler is famous for discovering the three laws of planetary motion, laws which Isaac Newton later re-derived with his universal theory of gravitation.
