One area where the conflict between quantum theory and relativity comes to the fore is in the gravitational constant, g, the quantity that describes the strength of gravity.
凸显量子理论和相对论冲突的地方之一是引力常数g,这个量描述引力的强度。

In 1998 astronomers discovered that the universe's expansion is accelerating at a rate consistent with a cosmological constant 10-120 times the value predicted by quantum theory.
Classical and quantum oscillators of quartic anharmonicity are solved analytically up to the second power of (weak-coupling constant) by using the multiple-scale perturbation theory.
