梵高《星空》中的秘密

The unexpected math behind Van Gogh's "Starry Night" - Natalya St. Clair

人的大脑最惊人的一个特性
One of the most remarkable aspectsof the human brain
就是能认清事物运作的模式并进行描述
is its ability to recognize patternsand describe them.
其中让我们最难了解的是
Among the hardest patternswe’ve tried to understand
流体力学中紊流的概念
is the concept ofturbulent flow in fluid dynamics.
德国物理学家维尔纳•海森堡说
The German physicistWerner Heisenberg said,
“见到上帝时 我要问他两个问题:
“When I meet God,I’m going to ask him two questions:
相对论和紊流为什么存在?
why relativity and why turbulence?
我确信他可以回答第一个”
I really believe he will havean answer for the first.”
和紊流同样困难的是用数学的方式理解它
As difficult as turbulence isto understand mathematically,
我们可以把它画出来
we can use art to depict the way it looks.
1889年六月
In June 1889,
梵高在太阳从圣雷米的圣保罗精神病院
Vincent van Gogh painted the view just before sunrise
其房间窗前升起时画出了景色
from the window of his roomat the Saint-Paul-de-Mausole asylum
他将自己耳朵割掉后
in Saint-Rémy-de-Provence, where he’d admitted himself aftermutilating his own ear
就住在那个精神病院
in a psychotic episode.
在画作《星月夜》中 他用漩涡状的笔触
In”The Starry Night,”his circular brushstrokes
画出充满卷云和涡状星星的夜空
create a night sky filled with swirling clouds and eddies of stars.
梵高和其他印象派画家以异于其前辈的方式表现
Van Gogh and other Impressionistsrepresented light in a different way
光影 而前期画家则著重於刻画动作 例如
than their predecessors, seeming to captureits motion, for instance,
波光嶙峋的水面
across sun-dappled waters,
或在湛蓝夜空中
or here in star lightthat twinkles and melts
加上乳白色波浪线条画出摇曳的星光
through milky waves of blue night sky.
这种效果是光的亮度
The effect is caused by luminance,
也即油画中色彩强度造成的
the intensity of the lightin the colors on the canvas.
我们视觉皮质里比较原生的部分
The more primitive partof our visual cortex,
判断光线对比和物体运动 而非辨识色彩
which sees light contrastand motion, but not color,
如果它们有相同的亮度区间
will blend two differentlycolored areas together
就会将两种不同的颜色混在一起
if they have the same luminance.
但视觉皮质中演化的分支
But our brains’ primate subdivision
会分辨颜色对比而不会将它们混合
will see the contrasting colorswithout blending.
当两种视觉处理方式同时发生时
With these two interpretationshappening at once,
印象派画中的光线变得非常突出
the light in many Impressionist works seems to pulse, flicker and radiate oddly.
这就是为什么印象派的作品
That’s how thisand other Impressionist works
倾向于用大胆的笔触
use quickly executedprominent brushstrokes
来捕捉细微的光影流动
to capture something strikingly realabout how light moves.
六十年后 俄罗斯数学家安德雷•柯尔莫哥洛夫
Sixty years later, Russianmathematician Andrey Kolmogorov
在其提出长度为R的水流中
furthered our mathematicalunderstanding of turbulence
能量与R的5/3次方成正比时
when he proposed that energy in a turbulent fluid at length R
即开创了数理上对紊流的理解
varies in proportion tothe 5/3rds power of R.
实验数据证实柯尔莫哥洛夫的模型非常
Experimental measurements show Kolmogorov was remarkably
接近紊流的流动方式
close to the way turbulent flow works,
虽然紊流完整的解释
although a complete descriptionof turbulence
仍是物理学中一项待解的难题
remains one of the unsolvedproblems in physics.
有能量梯度的紊流型态都相类似
A turbulent flow is self-similarif there is an energy cascade.
换句话说 大涡流传递能量给小涡流
In other words, big eddiestransfer their energy to smaller eddies,
这在其他规模中也适用
which do likewise at other scales.
举例来说 木星上的红斑云
Examples of this includeJupiter’s Great Red Spot,
星际尘埃等概莫能外
cloud formationsand interstellar dust particles.
2004年 科学家用哈伯天文望远镜
In 2004, using the Hubble Space Telescope,
观测到恒星周围有漩涡状的
scientists saw the eddies of a distant cloud
星尘和气体
of dust and gas around a star,
因此想起了梵高的《星月夜》
and it reminded themof Van Gogh’s”Starry Night.”
这就促使墨西哥 西班牙和英国的科学家
This motivated scientistsfrom Mexico, Spain and England
开始研究梵高画作里的颜色亮度
to study the luminancein Van Gogh’s paintings in detail.
他们发现梵高的画中
They discovered that there is a distinct pattern
有紊流结构
of turbulent fluid structures
类似柯尔莫哥洛夫的模型
close to Kolmogorov’s equationhidden in many of Van Gogh’s paintings.
研究者将这些画作数位化处理
The researchers digitized the paintings,
并测量两点像素间的亮度
and measured how brightness variesbetween any two pixels.
根据像素间的曲率
From the curves measuredfor pixel separations,
他们认为梵高患精神病期间的作品
they concluded that paintings fromVan Gogh’s period of psychotic agitation
精准画出了紊流的型态
behave remarkably similarto fluid turbulence.
而生活平静 稳定的时期
His self-portrait with a pipe,
叼着烟斗的自画像
from a calmer period in Van Gogh’s life,
则不符合紊流的结构
showed no sign of this correspondence.
其他画家所作
And neither did other artists’ work
乍看上去类似紊流的画
that seemed equallyturbulent at first glance,
像孟克的《呐喊》 也不符合
like Munch’s”The Scream.”
虽然我们可以说是梵高的天赋
While it’s too easy to sayVan Gogh’s turbulent genius
让他描绘出紊流的结构
enabled him to depict turbulence,
人们很难在承受痛苦时
it’s also far too difficult to accurately express the rousing beauty of the fact
准确表达如此困难的概念
that in a period of intense suffering,
梵高竟然能够理解并呈现
Van Gogh was somehowable to perceive and represent
世界上最深奥复杂的概念
one of the most supremelydifficult concepts
甚至人类前所未有的概念
nature has ever brought before mankind,
并用独特的慧眼
and to unite his unique mind’s eye
看透移动 水流和光影的奥秘
with the deepest mysteriesof movement, fluid and light.
