In the high energy physics laboratory called CERN, just outside Geneva in Switzerland, unstable muons (a type of fundamental particle that normally undergoes radioactive disintegration after about one millionth of a second) have been found to live longer by factor of thirty when travelling at high speed around a circular machine shaped like a large hollow doughnut.

在一个叫做 CERN 的高能量物理实验室，这个实验室在瑞士的日内瓦郊外，不稳定的μ介子（一种基本粒子，在百万分之一秒内会进行放射性衰变。）在绕着一个外形像中空的炸面圈形状的圆形机器中高速运行时，它的存在时间已经可以延长30倍了。

The messenger of the electromagnetic force is the photon with zero mass; the weak force that accounts for radioactive disintegration and causes the sun and the stars to shine is carried by the heavy W and Z boson particles; while the strong force is carried by gluon particles, which see to it that the atom nuclei hold together.

电磁力的信使是零质量的光子，弱作用力可以用来说明辐射衰变和太阳和恒星发光，其信使是重W和Z玻色子。
