In 1869 Russian chemist Dmitri Mendeleev followed suit and arranged the elements according to atomic weight to create the first version of his periodic table.

1869 年，俄罗斯化学家德米特里·门捷列夫进行效仿，根据原子量排列元素，创造出了第一版元素周期表。

Scientists also like when a new theory successfully predicts previously unobserved phenomena, like when Dmitri Mendeleev's theory about the periodic table predicted several undiscovered elements.

科学家们还喜欢一个可以成功预测以前没有观察到现象的新理论。就像门捷列夫的元素周期表预测了很多还未被发现的元素的性质。

So eventually the three laws combined into one by, surprise, our old friend Dmitri Mendeleev.

所以最终这三个定律合二为一， 出人意料的是， 我们的老朋友德米特里·门捷列夫 (Dmitri Mendeleev)。
