【TED】是一個會議的名稱,它是英文technology,entertainment, design三個單詞的首字母縮寫。它是社會各界精英交流的盛會,這里有當代最杰出的思想家,這里有當代最優(yōu)秀的科學家,這里有迸發(fā)著最閃耀的思想火花,這里孕育著最光輝的夢想。
Skylar Tibbits
MIT researcher Skylar Tibbits works on self-assembly the idea that instead of building something . we can create materials that build themselves, much the way a strand of DNA zips itself together. It's a big concept at early stages; Tibbits shows us three in-the-lab projects that hint at what a self-assembling future might look like.

Hints:
self-assembling
manufacturing
DNA
nanoseconds
longevity
complexity

Today I'd like to show you the future of the way we make things. I believe that soon our buildings and machines will be self-assembling, replicating and repairing themselves. So I'm going to show you what I believe is the current state of manufacturing, and then compare that to some natural systems.
So in the current state of manufacturing, we have skyscrapers -- two and a half years, 500000 to a million parts, fairly complex, new, exciting technologies in steel, concrete, glass. We have exciting machines that can take us into space 5 years , 2.5 million parts.
But on the other side, if you look at the natural systems, we have proteins that have 2 million types, can fold in 10000 nanoseconds, or DNA with three billion base pairs we can replicate in roughly an hour. So there's all of this complexity in our natural systems, but they're extremely efficient, far more efficient than anything we can build, far more complex than anything we can build. They're far more efficient in terms of energy. They hardly ever make mistakes. And they can repair themselves for longevity.
今天我想向各位展示 未來我們制作東西的方式。 我相信很快我們的建筑和機器 將能自我組裝, 自我復制和自我修復。 因此我要向各位展示 我所認為的制造業(yè)的當前狀況, 接著再將其與一些自然系統(tǒng)比較。
那么在當前的制造業(yè)中,我們有摩天大樓 —— 兩年半的時間, 50萬至上百萬個部分, 非常復雜, 使用了在鋼鐵,混凝土和玻璃方面的新技術。 我們有令人激動的機器, 可以帶我們進入太空—— 五年時間,兩百五十萬個部分。
但另一方面,如果看看自然系統(tǒng), 我們有擁有兩百萬種類型的 蛋白質, 能在一萬納秒內折疊起來, 我們能在大約一小時內 對帶有三十億堿基對的DNA進行復制。 這就是我們 自然系統(tǒng)的復雜性, 但它們非常高效, 比我們建造的任何東西都要高效, 比我們能建造的任何東西都要復雜。 它們在能源方面更加高效。 它們很少犯錯。 他們能自我修復保持長壽。
