In fact, subsequent work has shown that in a periodic table, elements should not be ordered strictly by atomic mass.

事实上，后来的研究已经证明，在元素周期表中，元素不应该严格按照原子质量来排序。

Mendeleyev was bolder than Meyer and even assumed that if a measured atomic mass put an element in the wrong place in the table, the atomic mass was wrong.

门捷列夫比迈耶更大胆，他甚至认为，如果测量到的原子质量在表中把一个元素对应于错误的位置，这个原子质量就是错误的。

He had a tube with electrodes potted in it filled with atomic hydrogen. And by applying a voltage, he was able to get the gas to glow.

With another scientist, Mister Fermi wrote a nineteen forty-seven report to the Atomic Energy Commission.

My desperation is lessened, however, by some of the more quantum physics theory which seems to suggest that, if at a sub-atomic level quarks can be in two places at once, then logically there must be a parallel universe where NZ were 130 all out and we are about to win.

The goal is to develop a range of areas where they can make improvements, such as new levels of control of semiconductor properties on a near-atomic level to light mixing and heat management.

What did happen was that the Enola Gay, an American B-29 bomber, dropped a uranium-based atomic bomb on the Japanese city of Hiroshima.
