But when they see two guys from the South like Cliff Richey and me, one white and one colored, both sharing a room and being close friends, it must do a little good."

If you want to add two vectors, you can add the arrows by the rule I gave you or just add the components of x of the two guys to get the component of the sum and likewise for the y.
如果要把两个矢量相加,你可以用我教给你们的箭头相接的方法,或者就将二者的 x 分量相加,得到和矢量的 x 分量,y 方向也是这样
In fact, it has to be some finite number, which is the acceleration of either of these two guys.
事实上它必须是有限的数值,也就是这两个物体某中某一个的加速度
"In the last two years, from big brand stores to the little guys,I would say a small business owner.

So it can't be an equilibrium, the exact prediction of the Downs model, two guys right on top of each other is not an equilibrium.
所以它不可能是一个均衡,确切的当斯模型的预测,两个一样的候选人不是一个均衡
"I had a call two months into it from the guys making the movie, "The Cove."

So, just, if you can take what I'm saying for a moment right now that in fact this should collapse in this very small time frame, we have to see that there's a problem with one of these two things, either the Coulomb force law or Newtonian mechanics. So, what do you guys think is probably the issue here?
所以如果你们考虑我,开始说的这个塌缩应该,发生在很短的时间里,那么这两者之一就有问题,要么是库伦定律,要么是牛顿力学,你们觉得应该是哪个的问题?
So I'm hoping you guys are comfortable with the notion of taking one or two or any number of derivatives.
我希望你们,能习惯求一阶,二阶,或者任意阶导数的概念
