 Leo nardo da Vinci was born on Apr il 15, 1452 in Vinci, Italy.  He was the

illegitimate son o f Ser Piero , a Florentine notary and landlord, but lived o n the estate and
was treated as a legitimate son. 

In 1483, Leonardo da Vinci drew the first model of a helico pter.  It did not lo ok

very much like our moder n day “co pter,” but the idea of what it could do was about the

Leonardo was an artist and sculptor.  He was very interested in motion and
movement and tried to show it in his art.  I n order to sho w movement, he found it help ful

to study the way thing s mo ved.  One su bject he liked to study was birds and how they

flew.  He spent many hours watching the birds and examining the str ucture of their
wings.  He noticed how they cupped air with their wings and how the feathers helped

hold the air .  Through these studies, Leo nardo began to understand ho w birds were able
to fly.

 Lik e many o ther men, Leo nardo began to dream of the day when people wo uld be

able to fly.  He designed a machine that used all the thing s he had learned abo ut flig ht,

and thus became the first model of a helicopter. 

 Poor Leo nardo had only one pr oblem, however.  He had no way to give the
necessar y speed to  his inventio n.  Yo u see, moto rs had not yet been invented and speed
was an impo rtant part o f the flying pr ocess.   It would be ano ther four hundred years
before the eng ine was invented and another  fifty years befo re it was put to the test in an

airp lane.   Leonardo’s dream o f a helicopter finally came to pass in 1936. 

The Italian painter, sculptor, architect, engineer, and scientist, Leo nardo died on
May 2, 1519, and was buried in the cloister of San Fio rentino  in Amboise.

Glass fibers are extremely strong; for their weight, they are stronger than steel.  
They are made by forcing molten g lass through tiny holes called spinnerets.  As many as

four hundred spinnerets are placed to gether, and threads of glass much thinner than

human hairs are drawn off at great speed-miles of thread per minute.  As they speed
alo ng, the threads are coated thinly with a type of g lue and twisted into a yarn.

The glass fibers are used with plastics to make boats and car bodies.  They are also
woven into heavy clo th for window draperies and into strong belts for  making tires


 A special kind of glass fiber is causing a revolution in commu nications.  A sig nal

of lig ht can be made to travel along the fiber fo r very long distances.  B y chang ing the
quality of the light, many messages can be sent at once along one strand of glass.  New

office build ings are being “wired” with glass fibers as they are built.  The g lass fibers will

be used to connect telephones and computers in ways that not long ago  were either
impo ssible or too  expensive.

 Glass woo l traps air in a thick, light blanket of fiber s.  This blanket is then put

into  walls and ceilings to keep warm air in during the winter and coo l air in dur ing the


 To make glass wool, mo lten glass is fed into a spinning dru m with many ho les in
it.   As the glass threads stream out of the ho les,  they are forced downward by a blast o f
hot air and through a spray of glues.  The threads are then further  blown about to  mix
them up as they fall in a thick mat o n a moving belt.

The glass we see thro ugh and drink out o f has many,  many other uses besides the ones

described here. 

 12. What was the author’s main purpo se in wr iting the article?
a.  To info rm you how special kinds of glass are made and used

Fo r centuries, people have searched fo r a way to replace dead and decaying teeth
with comfortable false teeth.  Many materials have been used to make a set o f false teeth. 

The teeth themselves should be made fro m a hard and durable material.  They shou ld be

secured to a soft material, making them easy to wear .  In the last two decades, dentists
succeeded in making durable false teeth that are comfortable, too .

 Two tho usand years ago, the Etr uscans made teeth out of animal bo ne and gold. 

These materials were used-with var ying degrees of success-up to the 1700’s.  When

George Washington was president, ivory from animals such as elephants became a
popular material fo r false teeth.  Doctor s and inventors also tried silver, peal, and agate, 

but teeth made fro m these materials wer e very exp ensive.  Perhaps the most successful

mater ial was porcelain, invented by a Frenchman abo ut two hundred years ago.  White,
strong, and r esistant to decay, porcelain is still used today for mak ing single teeth.

 Besides finding a material for  the teeth, inventors also had to find a way to secure

them in a person’s mo uth.  People tried wire, spr ings,  and many k inds o f g lue to

accomplish this.  In most cases, however, disco mfort and a likelihood o f the teeth falling
out plagued the person who wore them.

 Aro und 1844, an American dentist named Horace Wells used laug hing gas to put

peo ple to sleep before wor king on their teeth.  This inno vatio n made dental work a lot

less painfu l.  Soon after, an inventor created the fir st fo rm of rubber.  This was important
to dentistry because teeth could be attached to the rubber, and the rubber could be mo lded

to fit the shape of the mouth.  With these two developments, dentist could work without
causing pain and could fit teeth mor e carefully.  False teeth have beco me mor e available

and co mfortable since then,  and dentists have co ntinued to impr ove the making and use

of false teeth.

 The lens on a camera has only two tasks.  First, it must gather in as much light as
possible in o rder to activate the sensitive chemicals on the film.   Second, it must organize

the light rays so that they form a sharp image on the film.  These may so und like simple

tasks, but they are not.

 One of the sharpest lenses is merely a pinhole in a sheet of cardboard, metal,
plastic, or  a similar material.  If the pinhole is tiny enough, the image can be quite sharp,

but then very little light is admitted.  For most purposes, even the most sensitive film

would take too lo ng to reco rd an image.

 A glass lens is much better because it lets in much mor e lig ht and focuses it on the
film.  Yet simp le glass lenses are sharpest only in their centers.  As more o f the lens is

used, the image su ffers in sharpness.

One reason a simple lens can cause problems is that it is shaped like a section of a

sphere.  Spherical lenses do not focus perfectly on flat film, so  the image is slightly

disto rted, especially at the edges.  Another reaso n is that the lens can act partly like a
prism.  This means that some of the colors in the image will no t focus properly, and the

image will be fuzzy.

 One so lutio n is to block off all but the sharp- fo cusing center of the lens.  If you

block off the edges of the lens, ho wever, less lig ht will get to the film.  Early lenses had
to compromise between shar pness and light-gathering power.

 Very sharp lenses that admit as much light as po ssible can be bu ilt by making

them with several separate lenses, or elements.  A multiple-element lens has from two to

nine separate lenses.  Some elements are cemented together, and some have a gap
between them.  Further more, the elements are often made o f d ifferent kinds of glass, each

with a different ability to bend light r ays.  Some of the elements are there just for
co rrecting problems caused by the other elements!  The results are worth it, though: 

pictures can be taken in many different light conditio ns, and they have a sharpness you

can almost feel.

 37. What is the main disadvantage o f a simple lens that is made sharp by using just
