<span class='nw'>Biomimetics</span> learns from natural systems. // It tries to
understand / what nature does well / to work out problems. //
It
also tries to <span class='nw'>develop</span> new <span class='nw'>technology</span>. //
Although the word
biomimetics is new, / people have been looking to nature / to
develop <span class='nw'>various</span>  <span class='nw'>products</span> / for many years. //

  • Para Play

For example, / there are some plant seeds with sharp
points / in the wild. //
They may get on you / when you walk in the
forest. //
It is difficult / to pull them off your sweaters. //

One day in 1941, / <span class='nw'>George</span>  <span class='nw'>de</span>  <span class='nw'>Mestral</span>, / a Swiss engineer, /
came home from a walk in the mountains. //
He found <span class='nw'>burdock</span>
seeds / in his dog’s hair. //
Then / he took a close look. // He wanted
to know the reason / why those seeds got there so easily. //
He
found / that burdock seeds have small hooks / on their sharp
points. //
They easily catch on hair or <span class='nw'>fur</span>. // This is / how “[hook-
 and-<span class='nw'>loop</span>]  <span class='nw'>fasteners</span>” were first thought of / and invented. //

For a long time, / <span class='nw'>swimwear</span>  <span class='nw'>designers</span> have been working
hard / to make wear / that can help swimmers win their races. //
The designers thought and thought / about how humans could
swim like fish. //
They finally made a new <span class='nw'>type</span> of swimwear. // It
was made of a new <span class='nw'>material</span> / similar to shark <span class='nw'>skin</span>. //
More than
half of the swimmers wore it / in the 2000 <span class='nw'>Olympics</span>. //
Thanks to
many fine lines on the material, / one can swim faster through
the water. //

  • Para Play

After this, / other kinds of swimwear were made / by
learning from different <span class='nw'>creatures</span>. //
Fish and birds are some
examples. //
The designers studied / how these creatures entered
the water / or moved in it. //
Their main aim was / to create
materials and <span class='nw'>design</span> shapes / that <span class='nw'>reduce</span> water <span class='nw'>resistance</span>. //
As a result, / many swimmers broke world records. //

Biomimetics is also used / to <span class='nw'>solve</span>  <span class='nw'>environmental</span> problems. //
The 500 <span class='nw'>Series</span>  <span class='nw'>bullet</span> trains have a <span class='nw'>unique</span> design. // There is
a <span class='nw'>practical</span> reason / for the design of the front of the train. //
At
first, / the train made a loud noise / when it entered <span class='nw'>tunnels</span>. //
The
designers worked hard / to reduce this noise. //

  • Para Play

One day, / a designer watching birds / thought of an idea. //
It was / to make the train’s nose very long / like a <span class='nw'>kingfisher’s</span>
<span class='nw'>beak</span>. //
Kingfishers are very good at / <span class='nw'>diving</span> into the water / and
catching fish. //
The shape of their beak makes it possible / to dive
with little resistance / from the water <span class='nw'>surface</span>. //
In the same way, /
the [beak-like] shape of the train / reduces the air resistance / that
causes noise. //

Today, / many scientists look at nature / to get hints about
new technology. //
Some scientists, / for example, / are studying
a <span class='nw'>lizard</span> in the desert. //
It drinks water / little by little / through
its feet and <span class='nw'>spikes</span>. //
Scientists think it possible / to develop
technologies / for getting water in <span class='nw'>dry</span> regions. //

  • Para Play

Let’s take another look at nature. // Nature has solved
various problems / with surprising systems and designs. //
Living
things in nature / have survived through hard times. //
Those
that have survived millions of years / have been <span class='nw'>successful</span> /
because of their designs. //
Nature is a good designer / that has
built up <span class='nw'>effective</span> systems / without damaging the <span class='nw'>environment</span>. //
We should guard this treasure of ideas / and learn about
those systems. //
How about looking around / for hints of new
technology / <span class='nw'>hidden</span> around you? //
