Robotic Air Powered Hand with Elastic Ligaments.

And then for that unstable ligament, we put in a human donor ligament to stabilize the knee.

But what happens for your ligament when I need an intact ligament?

Then I went on to tear my ACL, the ligament in my knee, and then developed an arthritic knee.

What you see here on this toughness graph is the higher the black dot is on the graph, the higher the toughness.

But I know toughness when I see it.

Leathery chest pads that beat the heat.

Resilient Pakistan?

I got over the difficulty with my characteristic tenacity.

There were flexible, clear blood vessels.

He can now cut through tough animal hide.

But this is the face of resilience.

Yet, their draglines are not the toughest.

The tough hide is difficult to cut, even with a knife.

Mastering a foreign language involves a lot of patience.

I'm supposed to be the roughty toughty explorer type.

Tenacity is how I kept at it against all odds.

This is the comparison of the toughness of the dragline spilk spun by 21 species of spiders.

I use natural reed, because natural reed has a lot of tension in it that I cannot fully control.

And what you can see is that nearly all the spider draglines surpass them.

And I think we know that love is resilient enough for us to get out there and try.

We all have full confidence in the determination and resilience of the stricken nations to rebuild their countries as soon as possible.

That's an old fashioned, hard, gritty, physical stunt.

I use natural reed, because natural reed has a lot of tension in it that I cannot fully control.

Now, the counterlungs aren't high tech, they're just simply flexible bags.

I mean, this is literally human beings with super human strength and abilities.

This topic of resilience is very personal to me and in many ways has shaped my life.

Emergency preparedness is a big deal in disaster recovery because it makes towns safer and more resilient.

So I replaced the metal armature with a soft, fine mesh of a fiber 15 times stronger than steel.

The protagonists of my books are strong and passionate women like Rose Mapendo.

And if you want an example of perseverance, grit and strength in a beautiful, little package, it is her.

The Asian Cities Climate Change Resilience Network is restoring vital ecosystems like forest mangroves.

If you look right here at the two red arrows, they point to the toughness values for the draglines of nephila clavipes and araneus diadematus.

I would also like to pay tribute to the Secretary General, Mr. Kofi Annan, who has pursued those noble objectives with tenacity and farsightedness.

Your success will be determined by your own fortitude, your own confidence, your own individual hard work.

The friction in the process did not allow for meaningful results in an operational time frame using humans, PDFs and tenacity alone.

And this takes the long term steady courage of the day in day out struggle to educate, to persuade and to win acceptance.

But does the Chinese government really have the tools needed to keep its economy so resilient? Perhaps, but it is far from obvious.

So arguing against, a man who's been at the nitty, gritty heart of the energy debate and the climate change debate for years.

I'm fascinated by the beauty of it, the mutability of it, the malleability of it, and the fabulous shapes in which it can carve itself.

In fact, the toughest dragline in this survey is this one right here in this white region, a non orb web weaving spider.

Now I'm going to mark on the toughness values for nylon fiber, bombyx or domesticated silkworm silk wool, Kevlar, and carbon fibers.

For years these tens of millions suffered, endured, accepted hardships and sacrificed, and now they ask for their reward.

But when they get hydrated and they bond to each other, they create a stronger molecule, a stronger protein we call gluten.

They produce six different types of silk, which is spun together into a fiber, tougher than any fiber humans have ever made.
