One day he took us out into the sun and tried to show us how to find the focal length of a convex lens.

I gave you no help. The test was atrocious, but it proved one thing.

What does that convex lens do?

You know, you're swimming with the fogged goggles, you're swimming at 60 strokes a minute, so you're never really focused on anything, you don't see well.

Because it turns out that there is a kind of lens that we can devise, that has the right shape to produce this kind of effect.

We call this gravitational lensing.

A monocle?

Here, instead of through the lens of a genome, through the lens of digitized pieces of the historical record.

This is convex lens leadership.

In addition to the T mount 23mm fixed and 18 56 zoom lenses launched at the same time, the M Adapter T allows users of the Leica M series of lenses to attach and use the camera as well.

But this is a five meter telescope has about a quarter mile focal length.

The progress in negotiations on rules on regional trading arrangements has been limited, focusing mainly on transparency requirements.

So I went back there with a 28 mm lens.

Now, there is actually a little origami in the James Webb Space Telescope, but it's very simple.

Make clarity, transparency and simplicity a national priority.

So it's got the right shape to produce the lensing.

Don't be afraid.
