You take the third one, and you go from one to the other, and you see whether heat flows, when you touch one object, the middle object, between those two objects.
第三个物体就可以作为温度计,将它与第一个物体接触,再与第二个物体接触,观察它们之间热量流动的方向。
So,the point is,every object falling under gravity is given by the same formula, but there are many, many objects that can have many histories, all falling under gravity, and what's different from one object and the other object is, when was it dropped, from what height, and with what initial speed.
关键是,每一个受重力作用下落的物体,都有同样的表达式,但是各个受重力作用下落的物体,都有不同的初始条件,所以它们的区别在于,下落时刻,下落高度和初始速度
NASA warned the three astronauts inside about one hour before the object was to reach the area of the station.

The first sentence of your passage: "There is no art but one delivered to mankind that hath not the works of nature for his principal object."
你们篇子上的第一句话:,“只有一种艺术,当它传播到人间时,不带有自然的痕迹“
On February eighteenth, nineteen thirty, he discovered an unusual object after less than one year of searching.

One final example of an object permanence study.
最后举一个关于客体永存性研究的例子
For example, one word in the native language Carrier spoken in British Colombia means "he gives me an object like the fruit blueberries."

It's a supposition that whatever the object of theory might be, - theory itself must-- owing to whatever intellectual constraints one can imagine-- be of such and such a form.
不管理论是关于什么事物的,它自己都只能-,由于人们思想的局限性-,以猜想的形式存在。
One theory is that the military could object if the ruling party looks for friendship with South Korea to help save North Korea's economy.

So, for example, if you were trying to study the motion of some object, here is one example.
举个例子,如果你想研究某个物体的运动,这里有个例子
A comedy act in earlier days often included a part where one of the comedians would hit the others over the head with a soft object.

I think you can tell by analogy with what I did in one dimension that the position of that object at any time t is going to be the initial position plus velocity times t plus one half a t square.
你们可以类比一下我在一维情况下的结论,这个物体在任意时刻 t 的位移,等于初始位移,加上 v ? t + 1/2 ? a ? t^2
It takes an entire room to house one important object in this department.

Now, I hope you guys know that much calculus, that when you take a derivative of a function of a function, namely v square over 2 is a function of v, and v itself is a function of t, then the rule for taking the derivative is first take the v derivative of this object, then take the d by dt of t, which is this one.
我希望你们了解更多的微积分知识,当你对复合函数求导时,也就是说v^/2是关于v的函数,而v本身是关于t的函数,求导的法则应该是,第一步是这一部分对v求导,然后v再对t求导,得到这一部分
They object to the cost of the proposal, which could go as high as $one-trillion over 10 years, and they want to stop what they see as an expanding role for government in administering health care.
