Physicists cannot see subatomic particles directly, for instance, so they verify their existence by watching for telltale tracks that the particles leave in cloud chambers.

|
|
例如物理学家无法直接观察次原子粒子，因此他们观察那些粒子在云雾室中的轨迹，轨迹证实它们的存在，并透露了它们的性质。 |
|
Physicists have a precedent for such a change: the law of gravity that Newton formulated in the 17th century, which had various conceptual and experimental limitations, gave way to Einstein's general theory of relativity in 1915.

|
牛顿在17世纪所写下的重力定律，在当时受到许多概念上及实验上的限制，到了1915年便由爱因斯坦的广义相对论所取代。 |

|
除了超音速流体以外，物理学家还提出了好几个黑洞的类比模型。 |
|
Physicists investigating heavy-particle collisions believe they are on the track of a universal form of matter, one common to very high energy particles ranging from protons to heavy nuclei such as uranium.
|
|
|
研究重粒子对撞的物理学家相信，他们正在寻找某种物质的普遍结构，也就是寻找一种从质子到重核（如铀核）的超高能粒子共同结构。 |
|
Physicists know that in both types of material, the superconductivity is caused by electrons pairing up and gathering en masse in a single collective quantum state.
|
|
|
在这两种超导体材料中，超导电性是由于电子成双成对地集结在单一的量子态所产生，这是物理学家已知的部份。 |
|
Physicists posited bodies composed of scalar particles as long ago as the 1960s, and the idea was revived in the late 1980s, but it only really started to take hold four years ago.
|
|
|
在1960年代，物理学家断定物体是由纯量粒子所组成的，这种想法也一度在1980年代末期复苏，不过，它真正卷土重来，却是在四年前。 |
|
Physicists would love to develop a way of unifying the forces of nature (electromagnetism, gravity and so on) to produce a Theory of Everything.
|
|
|
物理学者们更愿意研究出一种方法来使自然界的各种力保持一致（如电磁力与地心引力等），以成就一部万物论。 |
|
Physicochemical determinations may include isoform, electrophoretic, and liquid chromatographic patterns, as well as spectroscopic profiles.
