Buzz Aldrin, Neil Armstrong, they walked on the surface, they planted this flag.
Soil's just the thin veil that covers the
surface
of land, but it has the power to shape our planet's destiny.
See, a six-foot or so of soil, loose soil material that covers the earth's surface, represents the difference between life and lifelessness in the earth system, and it can also help us combat climate change if we can only stop treating it like dirt.
Carbon that would have lasted maybe a year or two in decaying residue if it was left on the
surface
can stay in soil for hundreds of years, even thousands and more.
See, Dr. Brennan was already investigating how things like
surface
roughness can prevent the attachment of organisms like algae.
Sometime during or after surgery, bacteria latch onto the
surface
of a medical device, stay there, and cause a serious infection; and this makes it impossible for the body to heal.
Notice the tiny clusters of bacteria on the
surface?
The
surface
on the left is a smooth surface, and the one on the right is a sharkskin-like texture.
Notice how much bacteria's on the smooth
surface
compared to the sharkskin-like
surface?
This is because the sharkskin-like texture creates an inhospitable
surface
for bacterial attachment and growth.
It works on sharks, and it works here too because the texture takes advantage of principles of
surface
energy.
Now,
surface
energy is really a description of a detailed property of a
surface.
The roughened sharkskin-like texture creates a
surface
with greater
surface
energy.
You know, we interact with
surface
energy changes all the time.
Wax is a material with greater
surface
energy characteristics.
Now, we can't coat medical devices in wax, but we can change their
surface
texture.
We can prevent other medical complications through understanding the power of
surface
energy, things like frequent clogging, excessive blood clotting or poor healing interactions.
We've actually discovered that we can improve how medical devices are tolerated through subtly tuning the
surface
energy characteristics, like for example, we can prevent a lot of the excessive clotting that's occurring here on the smooth surface, compared to the sharkskin-like texture.
This means that we can actually match the required
surface
energy with the medical use to prevent complications, all with the power of sharks.
Places on land or close to the
surface
of the ocean have the advantage of access to sunlight.
But at the time when life began, the UV radiation on Earth’s
surface
was likely too harsh for life to survive there.
Consider this: Starting right here at the convention center, we can find the nearby aquarium, we can look at where we're sitting, and then we can cruise up the coast to the big aquarium, the ocean, and California's four national marine sanctuaries, and the new network of state marine reserves that are beginning to protect and restore some of the assets We can flit over to Hawaii and see the real Hawaiian Islands: not just the little bit that pokes through the surface, but also what's below.
Occasionally, throughout history, this concept of this very large cosmic perspective comes to the surface, and as a result we see transformative and profound discoveries.
And now what we're looking at is really creating a
surface
capture as opposed to a marker capture.
As Stephen Hawking famously said, we're just a chemical scum on the
surface
of a typical planet that's in orbit around a typical star, which is on the outskirts of a typical galaxy, and so on.
Sadly, their parents mistake bottle caps for food tossing about in the ocean
surface.
Trawling a zooplankton net on the
surface
for a mile produces samples like this.
Now, as I showed you in the earlier diagram, these reefs that we dive on start out near the
surface
and they go almost vertically, completely straight down.
That's looking straight up, by the way, to give a sense of how far the
surface
is.
Still, in this place, in this grassland where you can see our very first office there on that hill, four years later, there is this one green blop on the Earth's
surface
... (Applause) And there are all these animals, and all these people happy, and there's this economic value.
