日常產(chǎn)品背后匪夷所思的科學(xué)事實(shí)
VisWall: High Resolution Display Wall
高清屏幕墻的廣泛用途
Some walls can be windows into a world we can hardly imagine, the exquisite details of the stone-mason's craft, the mind-bending world of fractals, with the shapes may shrink, but they're all the same. Or the very blueprint of what we are all made of, a strand of DNA.
一些墻壁是通向我們難以想象的世界的窗戶，石匠雕刻的精密細(xì)節(jié)，引人入勝的不規(guī)則世界，其形狀可以縮小，但是其他的是完全一樣的。或者我們?nèi)梭w構(gòu)成的藍(lán)圖，DNA雙螺旋結(jié)構(gòu)。
"You can immerse yourself in your data, you know, you could do that in 3D, this software, and the VisWall have 3D capabilities."
“你可以沉浸在數(shù)據(jù)中，你可以用3D技術(shù)，使用3D軟件來(lái)處理信息，高清屏幕墻擁有3D功能。”
In this case, a churning twister, eat your heart out Hollywood. "You can try to describe the birth of a tornado in words are, we spent, having a very powerful 3D animation. I mean, the images speak for themselves."
在這個(gè)例子中，翻騰的龍卷風(fēng)，好萊塢中經(jīng)常用到的場(chǎng)景。“你可以嘗試用強(qiáng)有力的3D動(dòng)畫(huà)描述一個(gè)龍卷風(fēng)的生成。我的意思是，圖片本身會(huì)說(shuō)話。”
Measuring 14 by 8 feet, this video behemoth is known as "the VisWall". You can't get it at Best Buy though, you have to go to the Tufts University in a place called the Center for Scientific Visualization. With support from the National Science Foundation, Lionel Zupan helped bring the VisWall to life. The VisWall uses two rare screen projectors to display a picture four times the resolution of the best HD TV. Four times! Faculty and students from many disciplines use it. For example, a surgeon develops software so her students can practice their technique without cutting any tissue.
寬14英寸，高8英寸，這個(gè)巨大的視頻顯示器叫做“高清屏幕墻”。然而，在Best Buy你也買不到，你必須到塔夫茨大學(xué)一個(gè)叫做科學(xué)可視化中心的地方。在全國(guó)科學(xué)基金的支持下，Lionel Zupan將高清屏幕墻帶到生活中。它使用兩個(gè)罕見(jiàn)的屏幕投影儀來(lái)展示圖像，其分辨率是最好的高清電視的四倍。四倍！師資力量和許多學(xué)科的學(xué)生都使用這種屏幕墻。例如，一位外科醫(yī)生研發(fā)出一種軟件，這樣她的學(xué)生不需切開(kāi)任何組織就可以練習(xí)手術(shù)技巧。
"I can feel the texture itself and I can change instruments, so here I can actually cut, so I'm gonna try to rub the tumor."
“我能夠感覺(jué)到紋理，能夠變換工具，所以，我能夠試著切除腫瘤。”
Mathematician Boris Hasselblatt went to the wall to get a fresh view of a model that forecasts the population growth of certain animals and even though he has studied this for twenty years, what he bounced things off the wall, he saw something he had never seen before. "What's apparent at this scale ,with this resolution and detail and being at eye-height as well, is that all the curves of this sort seemed to be meeting right here." It turns out those curves indicate chaotic conditions. "That, I think, is one of the great things about this wall that, in fact, will get people to see things that, otherwise hard to see."
數(shù)學(xué)家Boris Hasselblatt使用屏幕墻來(lái)重審預(yù)測(cè)某種動(dòng)物數(shù)量增長(zhǎng)的模型。盡管他已經(jīng)研究該專題二十年的時(shí)間，然而，他從屏幕墻上仍然得到了自己以前從未見(jiàn)過(guò)的結(jié)果。“在這個(gè)范圍非常明顯，這種分辨率，細(xì)節(jié)和高度，所有的曲線似乎在這個(gè)地方匯合。”結(jié)果證明這些曲線表明混亂的條件。“我認(rèn)為，這是這種屏幕墻的優(yōu)勢(shì)之一，可以讓人們看到其他情況下很難看到的東西。”
These simulations and animations are just scratching the surface of the wall. Imagine what it would be like when we can get one of these babies at home.
這些模擬和動(dòng)畫(huà)只是體現(xiàn)了屏幕墻的表面。想象一下，如果我們家中都有能一面這樣的屏幕墻，會(huì)是多么美妙。
