He was probably familiar with the camera obscura, a device that projected an image through a pinhole and onto a screen in a darkened chamber (new research suggests he may have been introduced to it by the Jesuits of Delft).

维米尔可能对暗箱技术很熟悉，这种装置可以让图透过小孔，映到光线较暗的室内幕布上。(新的研究表明，这种技术可能是代尔夫特的耶稣会士介绍给他的)。

Now your pinhole projector is ready, so you can head outside, make sure the sun is behind you, hold the projector up to your eye, and then look for sunlight to come into the projector.

现在你的针孔影仪已经准备好了，这样你就可以出去观测了，确保太阳在你的背后，将影仪放在眼睛前，然后等待阳光进入影仪。

If you don't have these filters you can still observe the eclipse by making a pinhole camera using materials from around your home.

如果你没有滤光片，你可以选择使用针孔摄机，用一些家周围的材料就可以制作。

Meanwhile, nocturnal geckos have pupils that shrink into slits studded with pinholes in higher light conditions.

与此同时，夜间活动的壁虎在较高的光照条件下瞳孔会收缩成布满针孔的狭缝。

Another way to safely view the eclipse is to use a pinhole viewer.

另一种安全观看的方法是使用针孔观察器。

He actually walked away with like little pinhole scratches, but the lady passed away.

他实际上只受了点针孔大小的划伤，但那位女士却去世了。

But there's something really special about these two pinholes.

但这两个针孔有个非常特别的地方。

So the first thing you would do if you wanted to record the whole field is to get rid of that pinhole altogether, or the lens that simulates it with most cameras.

所以， 如果你想记录整个场， 首先要做的就是完全去掉那个小孔，者大多数相机用来模拟它的镜头。

Unlike a standard microscope that collects light from the entire thickness of the sample at once, a confocal microscope uses pinholes to actively reject light that's out of focus.

与标准显微镜一次性收集来自样品整个厚度的光线不同，共聚焦显微镜采用针孔技术主动排除失焦光线。

And if you’re looking for a safe way to see the eclipse, we’ve got you covered with our special SciShow pinhole projector card!

而且如果你正在寻找一种安全的方式来观看，我们特别推出的SciShow针孔影卡就能帮到你！

So we had, like so recently in our home we had a leak happen, a copper pipe, like a pinhole leak or whatever.

于是，就在最近，我们家里发生了一次漏水事件，是铜管出现了问题， 是针眼大小的漏洞之类的。

I couldn't afford a pinhole and a light bulb.

连无透镜照相机和灯都买不起。

Pinhole bored dwellings suggest that our sulfuria grows in them more abundantly than might be expected.

蛀孔居所表明，硫磺小蠹菌在其中的生长比预期的要旺盛。

Contrast this with the pinhole camera, where a ton of information is lost about that light field based on filtering through the hole.

与针孔相机相比，后者会因为光线通过孔洞时的过滤而丢失大量关于光场的信息。

And you can imagine the water drop, if it's like a balloon and you're trying to push it into those little 10,000 little pinholes, it doesn't like to do that 'cause it's gotta conform to all those pinholes.

你可以想象那水滴， 如果它一个气球， 而你试图把它挤进那万个微小的针孔里，它并不愿意那样做， 因为它必须适应所有这些针孔。 它更愿意停留在一点空气的口袋上。
