这就是为什么在只有垂直线的环境中长大的小猫和的大脑和那些生活在水平线环境中的猫的大脑有所不同。

That is why kittens raised so that they see only vertical lines have brains that look different from those raised in an environment with purely horizontal ones.

用最明显的图形来描述这个过渡的特性就是：当在两个圆之间绘制一条直线，直线与每个圆只有一个交点时，那么这条线就是两个圆的切线。

The quality of this transition is best visualized by a straight line drawn between two circles: the line's only point of contact with each circle is tangential.

特别具有直线路径得以改善，以及将线与分布在图形边缘的节点，以及更加容易管理的弯曲点联系起来的功能。

In particular the rectilinear routing is much improved, with the ability to attach lines to nodes distributed around the edge of shapes and to more easily manipulate bend points.

He chose the line so that--this is Gauss-- he chose the line to minimize the sum of squared distances of the points from the lines.

高斯选的这条线,所有点距离这条直线的平方和,是所有直线中最小的

Now there many ways I can connect these two points together. The simplest way is to draw a straight line. It's called the linear interpolation. My line is not so straight, right here. You could do a different kind of line.

最简单的办法是,像这样画一条直线,这叫线性插值,不过我的这条线画得不太直，你也可以用别的办法,比如一条抛物线。
