TheMakingofIsaacNewton牛顿＋苹果＝万有引力凡是上过学的人大概都知道这个典故：艾萨克·牛顿在看到从树上掉下的苹果后，就创立了著名的万有引力学说。

众所周知，Newton引力理论有一些无法解决的疑难，例如万有引力定律方程式的非洛伦兹协变性、水星近日点的附加进动等。

It is well known that , Newton 's gravitational theory has some intrinsic difficulties , such as the non-Lorentz covariant of the gravitational field , the orbital precession of Mercury etc. .

它与普通物质的相互作用，除了万有引力之外，很可能有弱相互作用，因此通常被称为弱作用重粒子（WeaklyInteractingMassiveParticles，或WIMPs）。

There is likely to be weak interaction between dark matter and ordinary matter besides gravitation interaction , so dark matter is usually called as " Weakly Interacting Massive Particles ( WIMPs ) " .

放射性产生的根源是一个太不稳定的原子违背了万有引力定律（我们物质世界存在的基本原理）并发生分裂，释放出两种粒子和一束类似于X光的γ射线。

The source of radioactivity is an atom so obese that it defies the laws of attraction gluing together our material world and spits out little pieces of itself -- two kinds of particles and a stream of gamma rays , similar to X-rays .

而任何传统的AHRS误差源自于其使用万有引力如同它参考辊间距估算值。两侧产生耦合动作损失。

For example , the MTi-G copes with transient accelerations ; a typical error source for any AHRS using the gravity as its reference estimating roll and pitch .

GSA的原理是通过将搜索粒子看作一组在空间运行的物体，物体间通过万有引力相互作用吸引，物体的运行遵循动力学的规律。

The particles in GSA are considered as a group of moving objects in the space , particles can attract by each other through gravity and move followed the rule of kinematics .
