Golden rice: two European scientists created a new strain of rice enriched in B-carotene, which the body uses to make vitamin A. This is a kind of transgenic plant(转基因植物)

No molecule in a living organism is a permanent resident. Within 7 years, most of the molecules in a human body have been replaced by new one! Individual? Decided completely by the genetic code? No! An individual's identity is continually re-established each and every moment

一、刚体及其运动形式 刚体(rigid body):在外力作用下,形状和大小都 不发生变化的物体.(任意两质点间距离保持不变的特 殊质点组) 刚体的运动形式:平动、转动

We will start by studying the motion of a particle. We think of particle as a body which has mass, but has negligible dimensions. Treating bodies as particles is, of course, an idealization which involves an approximation. This approximation may be perfectly acceptable in some situations and not adequate in some other cases. For instance, if we want to study the motion of planets it is common to consider each planet as a particle
