现在，我们所钟爱的对象当然
是心脏。
当你观察心脏时，你会发现
它其实是一个螺旋结构。
当你把目光移向心脏的尖端时，
你会发现，这个螺旋结构
早在17世纪60年代就被洛尔
描述为具有一个涡旋。
而且这些涡旋纤维是从外向内以
顺时针方向延伸，并且从内向
外以逆时针方向延伸。
这种顺时针和逆时针涡旋的
组合在自然界中很常见。
比如说，如果你看一朵
雏菊花蕾，你会看到同样
的顺时针和逆时针螺旋。
你还会注意到，
这些雏菊的花蕾在从中心
向外延伸时体积不断增大。
如果你观察这些顺时针和逆时针
螺旋在尺寸上的这种增大，
然后在上面画一条径向线，
你会发现，那就是自然
的生长模式。
当我们观察自然时，
你会发现许多顺时针和逆时
针的螺旋路径，仿佛它们是
相互对应的螺旋。
现在，当我们来看这些相互
对应的螺旋时，我们会看到
它们在自然界中非常常见。
比如说，如果你看一个贝壳，
你会看到贝壳同时具有
顺时针和逆时针的纹路。
如果你把那个贝壳的尖
端拉伸出去，
你会发现贝壳的尖端形成
了一条螺旋线。
而那条螺旋线和我们
在心脏里看到的非常相似。
当你观察这些螺旋结构时，
你会发现它们在许多动物
身上很常见。比如，
一种类似公羊的动物——大羚羊，
它的角中有顺时针和逆时针
的螺旋结构。
然而即使这些角在搏斗
时彼此对撞，
它们也不会折断。
因为大自然还有一个小巧妙招。
它会在螺旋之中再生成螺旋。
这是用一个结构去支撑另一
个结构的一种方式。
从某种意义上说，
大自然在结构之间
彼此之间有一种和谐，
无论是在外部还是在内部。
当我们审视这种和谐时，
可以追溯到许多年前，
公元前600年的毕达哥拉斯，
他谈到了黄金分割。小之于大，
正如大之于整体。
然而，在大自然中，
存在着一场和谐的交响乐，
在不同部分之间回荡。
这一点在1250年由
来自比萨的斐波那契（莱昂
纳多·达·比萨）加以阐述。
他谈到这种部分之间的和谐
概念——或者说一场交响乐，
像是一条对数螺旋。
当我们观察自然界时，
会看到对数螺旋朝着
不同的方向延展。
而或许我们最熟悉的一个，
就是DNA的对数螺旋。
一条双螺旋结构，
连接着糖和磷酸根离子
或这些部分它们就是生命宏
伟蓝图的设计图。
我们从DNA往上推演，
会发现我们看到一个螺旋星系，
在三千七百万英里…
百万光英里之外
展现出同样的螺旋结构。
但我们先回到人类本身。
当我们观察一个人时，
会发现我们都有逆时针和
顺时针的螺旋。
如果我们看看我们的指尖，
在和谐之中我们彼此相似，
但也存在一些差异。
而我们在指尖看到的这种
和谐部分同样延伸到
我们的心脏，在那里，
在心尖处我们再次看到
顺时针和逆时针的螺旋。
这是取自佩蒂格鲁
在1864年的一张图片。
作为外科医生，我们在解剖
中一直观察心脏，
看着内部和外部的螺旋袢
也就是球室螺旋袢和窦螺旋袢，
能看到在心脏周围有
一条小通路我一会儿
就会跟你们详细讲这个。
当我们从心脏的底部向上看时，
我们会看到同样的
顺时针和逆时针螺旋结构。
然后我们再看心尖。心尖，
无论是从外部还是内部看，
都具有相同的螺旋结构。
现在，这些心脏切片是由
Torrent-Guasp博士获得的，
他把这些图片收录在《生理学
手册》中。

Now the object of our affection, of course, is the heart. And as you can look at the heart, it is really a helix. And as you can look at the heart, it is really a helix. And as you look closer at the heart at the apex, And as you look closer at the heart at the apex,
you'll find that that helix was described in the 1660s by Lower as having a vortex. you'll find that that helix was described in the 1660s by Lower as having a vortex. And the vortex fibers go from outside in in a clockwise way, And the vortex fibers go from outside in in a clockwise way, and from inside out in a counterclockwise way.
and from inside out in a counterclockwise way. Now that combination of clockwise and counterclockwise vortices is common in nature. For example, if you look at a flower bud of a daisy, you'll see the same clockwise and counterclockwise spirals.
you'll see the same clockwise and counterclockwise spirals. You'll also note that the buds of the daisy increase in size You'll also note that the buds of the daisy increase in size as they go from the center and outward. And if you look at that increase in size of these clockwise and counterclockwise spirals,
and put a radial line across that, and put a radial line across that, you'll find that is the natural pattern of growth. And as we look in nature, you'll find many pathways of clockwise and counterclockwise spirals And as we look in nature, you'll find many pathways of clockwise and counterclockwise spirals
And as we look in nature, you'll find many pathways of clockwise and counterclockwise spirals as if they're reciprocal spirals. as if they're reciprocal spirals. Now, as we look at reciprocal spirals, we'll see they are common in nature. Now, as we look at reciprocal spirals, we'll see they are common in nature.
For example, if you look at a shell, For example, if you look at a shell, you can see a shell has a clockwise and a counterclockwise pattern. you can see a shell has a clockwise and a counterclockwise pattern. If you take the tip of that shell and draw it outward,
you'll find the tip of that shell forms a helix. you'll find the tip of that shell forms a helix. And that helix is very much like what we see in the heart. And that helix is very much like what we see in the heart. And that helix is very much like what we see in the heart.
And as you look at these helices, you'll find they're common in many animals. And as you look at these helices, you'll find they're common in many animals. For example, a ram-like animal like an eland, For example, a ram-like animal like an eland, who has clockwise and counterclockwise spirals in their horns.
Yet if these horns counteracted one another in combat, Yet if these horns counteracted one another in combat, they do not break. they do not break. Because nature has another little trick.
It produces spirals within spirals. That is a way of supporting one structure from another. And in a sense, nature has a harmony of structures one to another, And in a sense, nature has a harmony of structures one to another, And in a sense, nature has a harmony of structures one to another,
both outside and inside. both outside and inside. As we look at that harmony, we can go back many years to Pythagoras in 600 BC, As we look at that harmony, we can go back many years to Pythagoras in 600 BC, who talked about the golden section.
who talked about the golden section. The small is to the large as the large is to the whole. However, in nature, there is a symphony of harmonies However, in nature, there is a symphony of harmonies between different parts.
This was described by Fibonacci from Leonardo of Pisa in 1250. This was described by Fibonacci from Leonardo of Pisa in 1250. And he talked about this concept of harmony between parts or a symphony And he talked about this concept of harmony between parts or a symphony resembling a logarithmic spiral.

And perhaps one we know best is the logarithmic spiral of DNA. And perhaps one we know best is the logarithmic spiral of DNA.

We go from DNA upward, and we find that we see a spiral galaxy, 37 million mile... million light-miles away that shows the same spiral formation. 37 million mile... million light-miles away that shows the same spiral formation. But let's return a second to the human.
But let's return a second to the human. As we look at a human, we find we all have counterclockwise and clockwise spirals. As we look at a human, we find we all have counterclockwise and clockwise spirals. If we look at our fingertips, If we look at our fingertips,
we are similar in harmony, yet we have some differences. And that harmonic part we see in our fingertip also goes to our heart, And that harmonic part we see in our fingertip also goes to our heart, And that harmonic part we see in our fingertip also goes to our heart, where again we have the clockwise and counterclockwise spirals at the apex.
where again we have the clockwise and counterclockwise spirals at the apex. This is taken from a picture from Pettigrew in 1864. This is taken from a picture from Pettigrew in 1864. This is taken from a picture from Pettigrew in 1864. And we've looked at the heart as surgeons in anatomy,
looking at internal and external spiral loops or bulbospiral and sinospiral loops, looking at internal and external spiral loops or bulbospiral and sinospiral loops, looking at internal and external spiral loops or bulbospiral and sinospiral loops, with a little pathway around the heart which I'll talk to you about in just a moment. with a little pathway around the heart which I'll talk to you about in just a moment.
As we look from the bottom of the heart upward, As we look from the bottom of the heart upward, we see the same clockwise and counterclockwise spiral formation. we see the same clockwise and counterclockwise spiral formation. We then look at the apex.
The apex, both from outside and within, has the same spiral formation. Now these sections of the heart were obtained by Dr. Torrent-Guasp, Now these sections of the heart were obtained by Dr. Torrent-Guasp, Now these sections of the heart were obtained by Dr. Torrent-Guasp, who put these pictures in the Handbook of Physiology.
