In 1989, Japan’s Shinkansen Bullet Train had a problem.
1989年,日本新干线高铁出现了问题9;@eK7))tcvc.-B
It was fast — really fast — like, pushing 170 miles per hour fast.
这列高铁速度很快——是真的很快——时速差不多在170英里(约274km)左右r0]d4qthwBG
But every time it exited a tunnel — it was loud.
但每次驶出隧道的时候——声音都很大_t6s5xcsJ8%RR_i3^-
The noise was coming from a variety of sources,
尽管这一噪音的来源有很多,
but whenever a train sped into a tunnel, it pushed waves of atmospheric pressure through the other end.
但列车每次驶入隧道时,都会将压力波向隧道出口方向推进M9mOR^Rd2!IVRx
The air exited tunnels with a sonic boom that could be heard 400 meters away.
而压力波到达出口会产生能传出足足400米远的爆破声k^IwFQW*Sj_Y6v(uUYo)
In dense residential areas, that was a huge problem.
对人口密集的居民区而言,这就是个大问题P&jAKys.rw(w[%uX!f
So, an engineering team was brought in to design a quieter, faster, and more efficient train.
他们便请了一个工程团队为他们设计行驶起来更安静、更快也更高效的列车fNB)u2|.zZM
And they had one secret weapon: Eiji Nakatsu — the general manager of the technical development department — was a birdwatcher.
该团队刚好有个秘密武器:新干线技术开发部总经理中津英治是位观鸟爱好者Vk^.XGLD]H^u
Different components of the redesigned bullet train were based on different birds.
重新设计后的新干线各部位均以鸟类为设计灵感来源++DTsx6U9xjTQiVahx
Owls inspired the pantograph — that’s the rig that connects the train to the electric wires above.
猫头鹰是受电弓——连接火车和上方电线的装置——的设计灵感来源&M[.7|je++|;
Nakatsu modeled the redesign after their feathers,
中津以猫头鹰的羽毛为原型对受电弓进行了重新设计,
reducing noise by using the same serrations and curvature that allow them to silently swoop down to catch prey.
弯曲的锯齿状羽毛让猫头鹰能够悄无声息地俯冲下来抓捕猎物,中津利用同样的原理减小了受电弓产生的噪音~TFl[6S;JRxF
The Adelie Penguin — whose smooth body allows it to swim and slide effortlessly —
阿德利企鹅光滑的身体让它们游起泳来或滑行起来都显得毫不费力,
inspired the pantograph’s supporting shaft, redesigned for lower wind resistance.
这点启发了受电弓臂杆的设计,减小了风的阻力5I)d|IKOrB6veqQ5soa
And perhaps most notable of all was the Kingfisher.
最引人注目的灵感来源或许还数翠鸟V)A#dmw0)NBibYm1
The Kingfisher is a bird that dives into water to catch its prey.
翠鸟是一种需要潜入水中捕捉猎物的鸟yug%Z&U;CRy%
The unique shape of its beak allows it to do that while barely making a splash.
其独特的喙形让它们能够在捕捉猎物的同时几乎不会溅起任何水花n8uSez=q&yG
Nakatsu took that shape to the design table.
翠鸟的这一喙形也被中津带到了设计桌上0bzRDK3!Y0ix1d;&J
The team shot bullets shaped like different train nose models down a pipe to measure pressure waves,
研究小组将不同弹头造型的车头模型射入一个管道,以测量它们产生的引力波,
and dropped them in water to measure the splash size.
然后把它们丢入水中测量溅起的水花的大小zAbi(RE1|BXA&k
The quietest nose design was the one modeled most closely after the Kingfisher’s beak.
他们发现,噪声最小的车头设计是模仿翠鸟喙模仿得最像的那款=e^c7[ee6Zb
When the redesign debuted in 1997, it was 10% faster, used 15% less electricity,
重新设计后的新干线在1997年首次露面时,不仅速度提高了10%,耗电量减少了15%,

and stayed under the 70 dB noise limit in residential areas.
对住宅区造成的噪音也降到了70分贝这一上限之内Hnn3nNqOB9iwR4y1N^
And it did all that with the wings of an owl, the belly of a penguin, and the nose of a Kingfisher.
而这一切都源自于猫头鹰的翅膀、企鹅的肚子和翠鸟的鼻子带来的灵感d][+Eeb)kP*~([
There’s a name for design like this. It’s called biomimicry.
这类设计还有个名字——仿生设计sYm.3gP*A;AocbXp8+a
The people who design our world usually never take a biology class, believe it or not.
不管你信不信,那些设计了我们的世界的人往往都没上过生物课!k_-YIqooE~rfx
So they're novices in how the world works.
他们对这个世界是如何运作的这一问题的了解也仅限于新手水平I.[;M4qqaXc3(Za
That’s Janine Benyus.
这位是珍妮·班娜斯XwTWbqSI9_B7iQ@*D
Back in 1997, she wrote the book that coined the term “Biomimicry”.
早在1997年,她就创作了那本首次提到“仿生学”这个词的书gbPuKceuLb&KJLo-MB
It told the story of the innovations in computing, energy, and health that were inspired by structures in the natural world.
书中讲述了计算机、能源和健康等领域,受到自然界各种构造启发的各项创新*lML[5e~gRto7hh
Stick like a gecko.
像壁虎一样牢牢吸住C)UyED8vs.
Compute like a cell.
像细胞一样计算~Uowtb2WrX0@,2^^
Even run a business like a redwood forest.
甚至像红杉林一样经营企业^HPT3zN7QDqyLmO2aT
Benyus has since worked as a consultant for various companies,
从那以后,班娜斯一直在各大企业当顾问,
trying to get them to understand how to take design ideas from nature.
设法让他们理解如何从自然中汲取设计灵感7XP2i425W]0=
That might mean studying prairie dog burrows to build better air ventilation systems,
这可能就意味着研究土拨鼠的洞穴,以便设计出更好的通风系统,
mimicking shark skin to create bacteria-resistant plastic surfaces for hospitals,
模拟鲨鱼的皮肤,以便为医院设计出耐细菌的塑料表皮,
or arranging wind turbines in the same drag-reducing pattern that schools of fish swim in.
或者按照鱼群游动时的减阻模式来排放风力涡轮机4lmduCDTGV
