  • [Gasps] Was it -- that was it, wasn't it?

    (驚嘆) 喔—— 這,就是這樣了,不是嗎?

  • I think we've been doing it so long we don't know what perfect looks like [Laughs]

    我想我們已經忙了這麼久了,卻不知道它看起來多麼的完美 [笑]

  • What's up, I'm Destin.

    嗨,我是德斯汀

  • I, I do not even know how to start this video

    我不太知道該怎麼開始切入這支影片

  • I'll just try to explain it and -- I mean, this is a huge deal.

    我先試著解釋一下 - 我的意思是,這是一個很大的議題

  • Five years ago, someone sent me a link and I opened it, and I love fluid dynamics

    五年前,有人發給我了一個連結,我打開了它

  • and this was cool, it was like this lab video from Australia of two vortex rings colliding

    我喜歡流體動力學,而很酷的是

  • and they did this really weird thing, and then these other rings poked out

    這個來自澳洲實驗室的影片中有兩個水中漩流相撞

  • and I was like "Oh, that was -", and my brain didn't even understand.

    他們做了這個非常奇怪的事情,結果竟然冒出來了其他的環

  • So I hit refresh, and refresh, and refresh

    而我的反應就像“哦,那是—— ”,我的大腦甚至無法理解

  • And the more I watched it, the more I realised, this is really special.

    所以我點擊重播,一次又一次的點

  • There's some complex fluid mechanics going on here that needs to be understood.

    而且當我看的越多,我越了解到,這真的很特別!

  • So, I started Googling, because that's what you do. I want to learn more about it

    就像這裡有一些複雜的流體運作情況需要被了解

  • and I found some research papers, where people had numerically tried to figure it out

    所以,我開始用 Google 找資料,因為這就是你要做的我想更了解這個現象

  • but nobody's actually done it. Why?

    而我發現了一些研究論文,人們試著用數值去解釋這個現象

  • So I started trying to do it myself.

    但卻沒有人實際做過實驗怎麼會這樣?!

  • That didn't work, at all.

    所以我開始試著自己做這個實驗

  • I started trying to get help. So I got some undergraduate research students to help.

    卻完全沒有成功過...

  • They had some limited results. But it's a very difficult problem.

    我開始嘗試尋求幫助所以我得到了一些本科研究生的幫助

  • So at this point, I realised: this is serious.

    他們做出了一些成果但這是一個非常棘手的問題

  • I mean, this has not been recreated since cameras looked like this, right?

    所以在這一點上,我意識到:這很嚴重

  • So you can't Google it, money can't buy it. If I ever want to see it better than this [gestures to camera], I have to do it myself.

    我的意思是,這個現象一直以來都沒有被重現

  • So I used some Patreon funding, and I went to this friend of mine.

    自從攝影機長的像這樣之後,對嗎?

  • He's a motion control engineer. His name is David Lenderman.

    所以你無法用 Google 找到,用錢也買不到

  • We've been working on this for well over 3 years.

    如果我想要看到比這個品質更好的結果我必須自己做出來

  • I mean, this has descended into madness. We've created all different types of prototypes.

    所以我用了一些 Patreon 資金然後我去找了我的這位朋友

  • I don't know how to explain why, other than, "This had to be done."

    他是一名運動控制工程師他的名字叫 David Lenderman

  • So I wanted to see the vortex collision, recreated with modern imagery technology. And that's what this video is.

    我們已經為此試驗了幾乎超過3年

  • I hope you enjoy it.

    我的意思是,這已陷入瘋狂我們已經製作出了所有不同類型的原型

  • So, in 1992 in the journal "Letters to Nature," there was an article written by

    我不知道該怎麼解釋為什麼要這麼做

  • Doctor T. T. Lim, now you see this right here on the toolbox

    除了因為:這件事必須被完成

  • in David's shop, because for the past year, we've been trying to recreate this device.

    所以我想看到 用現代圖像技術重新呈現的渦旋碰撞

  • It's a device he created--you may have seen the video-- two vortex rings were collided together,

    這就是這個影片的內容

  • and they created these secondary rings that came off the edges.

    我希望你喜歡它

  • Now the problem with this, is, it was filmed with a potato.

    因此,在1992年的期刊 “Nature” 上

  • We're going to use this, it's a Phantom v2511,

    有一篇由 T. T. Lim 博士寫的文章

  • and the goal here is to get those secondary rings.

    現在您可以在這個工具箱上看到在大衛的商店裡

  • [MUSIC]

    因為在過去的一年裡,我們一直在嘗試重新製作這個設備

  • You have an electromechanical actuator that's driving

    這是他製造出的一種設備你可能已經看過了影片:兩個渦環碰撞在一起

  • a pneumatic cylinder, which is pumping air to a valve

    而且他們製造出了這些從邊緣跑出來的二級環

  • so that you can control the input to both cylinders at the same time.

    現在問題是它是用 "馬鈴薯" 拍攝的 (比喻畫質不好的攝影機)

  • DAVID: Right, which seems to be fairly effective and predictable.

    我們接下來會使用這個這是Phantom v2511

  • DESTIN: So it's basically a very precisely calibrated syringe with a stroke of a certain throw, OK.

    而目標是得到那些二級環

  • DAVID: It's more of a messy process.

    [音樂]

  • DESTIN: I'm ready.

    你有一個機電致動器正在驅動

  • DAVID: Doesn't look bad for the first one.

    一個氣動缸,將空氣泵送到閥門

  • DESTIN: That wasn't bad.

    這樣你就可以同時控制兩個氣缸的輸入

  • How do you change the water?

    David:對,這似乎是相當有效和可預測的

  • DAVID: Pump it out.

    Destin:所以它基本上是一個自動的、非常精準的注射器,具有一定的衝程

  • DESTIN: That is impressive.

    David:沒錯Destin:了解

  • You want to do the mixing routine?

    David:這更像是一個混亂的過程

  • Really good one on that side.

    Destin:我已經準備好了

  • [MUSICAL IMPACT]

    David:第一個看起來並不壞

  • DESTIN: Ohhhh it's pretty.

    Destin:那還不錯

  • DAVID: That was a good one.

    Destin:你要怎麼換水?

  • DESTIN: That was pretty.

    David:抽出來吧

  • [GASP]

    這令人印象深刻

  • When you get done with a shot it looks like you're growing your own organs in the aquarium.

    你要做混合動作嗎?

  • DESTIN: Opening...

    那一側的環真的不錯

  • [BOTH EXCLAIM]

    Destin:哦!這個很漂亮!

  • Ohhh, I triggered on that.

    David:那一個很好

  • So this is what, this is round how many? Five? Four? Seven? [CHUCKLES]

    Destin:那很漂亮

  • [MUSIC CONTINUES]

    [倒吸一口氣]

  • 750...

    當你完成一次射擊後,這裡看起來像是你在水族箱裡培養你的器官。

  • We are refilling the tank for the hundred somethingth time.

    Destin:打開......

  • It's going to work.

    Destin:哦,我觸發了這個

  • That is going to work.

    那麼這是第幾次?五?四?七? [笑]

  • Oh

    750 ...

  • I think today might be the day.

    這是我們第幾百次把水注滿這個水缸

  • [MUSICAL IMPACT]

    這將會成功的

  • Haha, got the secondaries.

    這一定會成功的

  • Look at those, man.

  • Wow

    我想今天 應該就會成功了

  • [MUSIC CONTINUES]

    哈哈,我們做出了二級環!

  • I started this process simply wanting to recreate something that captured my imagination.

    看看那些,兄弟

  • But obviously it morphed into something much larger than that.

  • It wasn't about fluid dynamics or motion control.

    我開始這個過程只​​是想重新創造一些能夠吸引我想像力的東西

  • It was about patience and persistence.

    但顯然它變成了比那更大的東西

  • The value of surrounding yourself with people who get this, cannot be overstated.

    這不是關於流體動力學或運動控制

  • David wouldn't quit, which taught me to power through,

    而是關於耐心與堅持

  • even when it might not make sense on paper.

    這份與那些堅持的人共同作業的價值,不能過分誇大

  • Every time we failed, we learned something.

    David是不會放棄的,而這教會我要保持頑強

  • So ask yourself this:

    即使它在論文上可能沒有意義

  • What are you too intimidated to try?

    每當我們失敗,我們都會學到一些東西

  • All you gotta do is fill the tank back up, and give it another shot.

    所以問問自己

  • So three years, and a bunch of ink in an aquarium?

    “你有什麼太害怕嘗試的?”

  • No, this is so much more than that -- this is what taught me persistence.

    你唯一要做的就是再次注滿整個水缸,重新再做一遍

  • For you, example, what is your vortex collision?

    那麼三年了,水缸裡還有一堆墨水?

  • Is it something at school that's hard, a subject?

    不,這遠不止於此 - 這就是教會我堅持不懈的原因

  • Is it a project at work that you don't think you can overcome?

    對你來說,例如,你的渦旋碰撞是什麼?

  • Is it some skill you want to learn?

    這在學校裡是不是很難,一個主題?

  • What is the thing you have to overcome,

    這是一個你認為自己無法克服的工作項目嗎?

  • and how are you going to do it?

    這是你想要學習的技巧嗎?

  • The payoff here, was visual data that was not filmed with a potato.

    你需要克服的是什麼

  • This is a big deal, because we can now see things,

    你打算怎麼做?

  • we could never see before.

    這裡的回報是沒有用馬鈴薯拍攝的視覺數據

  • For example, if you look closely,

    這是一個很大的突破,因為我們現在可以看到

  • you can see as the outer ring of the vortex starts to break up,

    我們以前從未見過的東西

  • you get these little nodules that have a low pressure spot right in the middle.

    例如,如果仔細觀察

  • and Don Pettit, an astronaut, his theory is that, that low pressure zone starts to suck material away

    你可以看到渦旋的外環開始分裂

  • from the outside perimeter, breaking up the ring into regular intervals.

    你會得到這些在中間有低壓點的小結節

  • The next part, however, remains a mystery:

    而太空人 Don Pettit 的理論是,低壓區開始吸走物質

  • how does that, once it breaks up, turn 90°, and turn into a ring facing outwards?

    從外圍開始,將環分成規則的間隔

  • That is the mystery, and now we have the visual data to look at it.

    然而,下一部分仍然是一個謎

  • You can see that over on the second channel, I have twelve hours of footage of everything

    “一旦它破裂,轉向90°,變成一個朝外的環,怎麼樣?”

  • we recorded, it's all there, go check that out if you're interested in seeing how all this stuff works.

    這就是謎,現在我們有了可視化數據來觀察它
