That is what really got me started." Starting from this guitar made out of a cardboard box and fishing line,and this one, bearing serial number "one."

I have shown that by taking Avogadro's number of individual ion pairs and putting them all together in a line, the system's energy became more negative.

我推导出了,从每一个离子对中抽出阿伏加德罗常数,再把它们放在一起在一列中，这个系统的能量就变得更负。

If I have Avogadro number of these things in a long line, you can bet it is going to be a solid.

如果在一条直线上,这些东西有阿伏伽德罗常数那么多，你肯定会说它是固体。

If n is greater than zero, I decided I would say, "You picked a positive number, backslash n," so put the cursor on the next line, else if n was not less than zero, I say, "You picked a negative number, backslash n."

如果n比0大，我就决定来说：,“你选择了一个整数，反斜杠n“，所以你把光标,放在下一行，另外如果n不小于0，我说：,“你选择一个负数，反斜杠n“
