如果物体处于静止状态或作匀速直线运动,只要没有外力作用,物体将保持静止状态或匀速直线运动状态。
Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it.
这种我们能创造一个每个人的能力都忠实地被分级,好的就到顶端,坏的就到底部,而且保证过程毫无差错,这是不可能的。这世上有太多偶然的契机,不同的机运,出身,疾病,从天而降的意外等等,我们却无法将这些因素分级,无法完全忠实的将人分级。
To live is to choose, and to choose is to renounce.
Life is about making mistakes and learning from them. That's how you grow.
