Using the same two initial arm lengths an Angle of 90 degrees between them produces a third side which is the square root of 2 times the arm length.
使用最初的相等的两个手臂长度和之间的夹角为90度，可以产生第三条边，而变成等于2的平方根乘以手臂的长度。
The length of the diagonal side will be the square root of 2. This diagonal will be used to construct the next square root by employing a similar method.
对角线的长度是2的平方根。应用类似的方法，这个对角线会被用来构造下一个平方根。
If I make it four times shorter-- l 2 the square root of four is two.
如果缩小4倍-,缩小4倍-，l，four，times，shorter--,4的平方根是。
t1/t2 2 would be the square root of h1 divided by h2 That is the dimensional analysis argument h1/h2 that we have there.
也是这样2，And，so，the，time，t1，divided，by，t2,通过之前的量纲分析得到2,它等于,根号下。
If you are near Earth in orbit, you are eight kilometers per second, and eight times the square root of two 2 is exactly that 11.2.
如果你在轨道接近，地球，那是8千米每秒，8乘以2平方根，正好是11。
The period, which is 2 pi times the square root of l over g, if you substitute in your length of 5.1 meters, you will find 4.57 seconds.
周期，等于2π,乘以l/g的平方根，如果把长度为5。1米,代入，会得到4。57秒。
Finally the 180 degree Angle will produce a side of length 2 arms, the square root of 4.
最后180度的夹角的三角形形成第三边的长度是臂长的2倍，4的平方根。
