This is the audio script:
It's early morning in a small village in Kenya, Africa.
Women and children are carrying heavy containers of water on their heads.
They walk many miles to get this water.
It's hot, and they are tired.
They can only carry a few containers a day.
A young British woman learns about the problem she wants to help.
Who is the young woman?
Her name is Emily Cummins.
How did she help?
She invented a water carrier for the people in Kenya.
They can pull it like a suitcase.
Cummins is an engineer.
She designs useful products for places without many natural resources.
These places often don't have a lot of water.
They also don't have a lot of oil, coal, or gas.
These resources are not renewable.
That means you can't replace them when you take them from the earth.
Cummins' products don't use oil, coal, or gas.
They use other sources of energy, such as the sun.
This makes the products sustainable.
People can continue to use them in the future without hurting our planet.
How did Cummins get started?
As a young child in England, she loved to work with her grandfather in his workshop.
He taught her how to use his tools.
He showed her how to make toys and jewelry boxes from small pieces of metal.
She designed her first product when she was in high school and just 15 years old.
Her grandfather had arthritis.
He couldn't squeeze a tube of toothpaste with his hand.
Cummins invented a tube with a lever.
The lever pushes the toothpaste out of the tube.
You don't have to squeeze the tube.
While she was still a high school student, Cummins designed a new kind of refrigerator.
Why?
Refrigerators normally use a lot of electricity.
They are too expensive for many people in developing countries.
Cummins' refrigerator is not expensive.
Here's how it works.
One container of the refrigerator keeps food and medicine clean and dry.
This container sits in another container filled with water and sand.
The sun's energy makes the water in the sand evaporate.
In other words, the water goes into the air and takes heat from the sand with it.
This cools the sand.
The cool sand keeps the food and medicine cool.
The design is very simple and it uses cheap local materials.
People can even make the refrigerator themselves.
After leaving school, Cummins spent five months in Africa.
She wanted to learn more about life there so she volunteered at a school in Namibia.
There, she could test and improve her designs.
Her refrigerator became a great success.
Today, it helps thousands of people.
Cummins studied business at the University of Leeds in England.
Today, she continues to design sustainable products.
She has won many awards for her designs.
Her inventions are famous because they use local resources.
They don't hurt the planet and the materials are all recyclable.
Do you have ideas for sustainable products?
Maybe you too can become an engineering superstar.

This is the audio script:
Chuhachi Ninomiya was a young man with a dream.
He wanted to invent a flying machine.
He watched birds fly for hours and hours.
He also studied insects and flying fish to get ideas.
Did Ninomiya's dream come true?
The story of his life will give you the answer.
Ninomiya was born in Japan in 1866.
As a boy, he loved flying kites.
People called him kite flying Chuhachi.
Ninomiya also loved to design kites.
His kites were unique because they had pockets.
Some businesses used Ninomiya's kites for advertising.
They put advertisements into the pocket of a kite.
The pocket opened and let the ads fall to the ground.
Then, the pocket closed again.
Ninomiya built his first model of a flying machine in 1891.
He was just 24 years old.
He called his model the crow, which is the name of a kind of bird.
It had a propeller and landing gear, but its wings did not move.
Ninomiya's model actually flew.
In 1894, Ninomiya became a soldier in the army.
He thought flying machines could be very useful in a war.
He gave his engineering plans to the army.
The plans had drawings and specific directions for building a flying machine.
However, the army didn't pay attention to Ninomiya.
They said, humans are not supposed to fly.
They thought he was crazy.
Ninomiya left the army in 1898.
He continued to design airplanes.
He started to build a plane that was more like a modern airplane.
Ninomiya's plane wasn't a model this time.
It was a real full-size plane.
The plane was almost finished.
All Ninomiya needed was an engine, and he ordered one.
Then one day, he read in the newspaper about the Wright brothers.
These two men from the United States flew their first plane in December of 1903.
Ninomiya read about the brothers' success just one day before he received his engine.
This was bad news for Ninomiya.
He stopped building his plane, and he never built another one.
After that, he became a Shinto priest.
Most people think the Wright brothers designed the first airplane, but this isn't true.
Ninomiya designed and flew model planes many years before the Wright brothers did.
However, the Wright brothers flew their first plane before Ninomiya finished his full-sized
plane.
Unlike Ninomiya's plane, the Wright brothers plane did not have landing gear.
It also had a kind of wing that wasn't as modern as the wing on Ninomiya's plane.
In 1991, an expert in aviation used Ninomiya's engineering plans to build an airplane.
He said that Ninomiya's plane was better than the Wright brothers plane.
Ninomiya never lost his interest in airplanes and flight.
He even built a shrine for people who died in airplane accidents.
Before he died in 1936, he received an apology and an award from the army.
Today, he has the greatest honor of all.
The Japanese call him the father of Japanese aircraft.

13. The Alaska Pipeline is the pipeline in the world.
14. It crosses three mountain and more than 800 rivers and streams.
15. It is about 20,300 miles, 32,670 kilometers, and it is the longest in the world.
This is the audio script:
Humans are great builders.
Examples are all over the world.
The Egyptian pyramids, the Panama Canal,
and the Alaska pipeline are just a few.
Thousands of people worked on these enormous structures.
What makes these structures such amazing achievements?
Is it their size? Is it their beauty?
Is it the number of workers? Is it the danger of the work?
The ancient pyramids of Egypt are still a mystery today.
No one knows exactly how the Egyptians built them.
The biggest pyramid is the great pyramid of Giza.
The Egyptians built it in about 2550 BCE.
The workers used 2.5 million limestone blocks.
The great pyramid covers 123 acres, 50 hectares,
or 500,000 square meters.
It's 480 feet, 146 meters high.
The sides are 755 feet, 230 meters long.
How did the workers build the great pyramid?
There were no wheels at the time, so there were no cranes or pulleys.
Experts think the builders used simple machines, such as levers and ramps.
The great pyramid took over 80 years to build.
Approximately 30,000 people worked on it.
What was the most dangerous engineering project?
It was the Panama Canal.
This waterway in Central America is 50 miles, 80 kilometers long.
It lets ships pass between the Atlantic and Pacific oceans.
The French started the project in 1881.
However, the work was too difficult and they stopped.
The United States continued the project in 1904 and completed it in 1914.
A total of 56,307 people worked on the canal.
The area around the canal was very dangerous.
It had a tropical climate.
That means it was very hot and wet, with about 105 inches, 267 centimeters, of rain a year.
The heavy rain often flooded the rivers.
There were mosquitoes.
No one knew that mosquitoes caused malaria.
Thousands of workers died from malaria and accidents.
One of the greatest engineering achievements of the 20th century was the Alaska Pipeline.
In 1968, an oil company found the largest oil field in North America.
How could they get oil from Alaska to the rest of the United States?
They worked with other oil companies to build a pipeline.
The Alaska Pipeline is the longest pipeline in the world.
It carries oil for 800 miles, 1,287 kilometers, through the cold hard Alaskan wilderness.
It crosses three mountain ranges and more than 800 rivers and streams.
More than 70,000 workers built it.
They worked for nine years in sub-zero temperatures.
They completed the work in 1977.
Since then, over 15 billion barrels of oil have traveled through the pipeline.
There are many other amazing engineering projects around the world.
For example, the Great Wall of China was the largest building project in history.
The Great Wall is approximately 4,500 miles, 7,242 kilometers long.
Another example is the Pan-American Highway.
It is about 20,300 miles, 32,670 kilometers, and it is the longest road in the world.
It goes through Canada, the United States, Mexico, Central America, and South America.
Can you think of other examples of great engineering projects?
Which project do you think is the greatest of all?

15. Chiang knows one thing.
This is the audio script:
Chiang Yan is one of the most successful business women in the world.
She made billions of dollars.
How did she do it?
Does she sell computers?
Does she sell diamonds?
Does she sell real estate?
No.
She sells trash.
In fact, many people call her the Queen of Trash.
Chiang was born in China in 1957.
Her family wasn't rich.
When Chiang was a young woman, she worked as an accountant.
She saved some money and she moved to Hong Kong.
There, she became interested in the paper Trash Business.
She and two partners started a company with a small amount of money.
The company collected paper Trash and sold it to paper mills.
Then Chiang had an idea.
China had a shortage of paper.
Chiang knew just where to get paper for China.
In 1990, she and her husband moved to Los Angeles.
There, they found paper, tons of it.
They drove their van to garbage dumps around Los Angeles.
They collected the paper Trash.
Then they exported the Trash to China.
What did Chinese factories do with Chiang's paper Trash?
They recycled it and made cardboard, a thick, stiff paper.
Then they made the cardboard into packing boxes.
They used the boxes to pack made in China products, such as toys, electronics and clothing.
They sent these products to the United States and Europe.
In 1996, Chiang moved back to China.
She started her own paper making company called Nine Dragons Paper.
Today, Chiang buys paper Trash in the United States and Europe.
She sends it to her factory in China.
Then she makes it into materials for packaging.
Big companies like Sony use her packaging.
When people in the United States and Europe receive their made in China products,
they throw the packing boxes away as Trash.
Chiang gets the boxes and recycles them again into packaging.
What kind of person is Chiang?
She's a little mysterious.
She almost never gives interviews.
Other business people say she's good at making deals.
She develops good strategies for her business.
She works very hard and she expects her employees to work hard too.
The Queen of Trash is a hard working business woman.
She started her own company and she made it grow.
What will her future be?
She hopes she will be successful for many years.
Chiang knows one important thing.
There will always be paper Trash that she can recycle again and again.

This is the audio script:
Did you know that many inventions began as accidents?
Some of these accidents even became big business ideas.
They gave us products that people all over the world use every day.
In 1886, in the United States, a pharmacist named Dr. John Pemberton tried to invent a
medicine.
Pemberton wanted a cure for headaches.
He mixed several ingredients together.
No one knows exactly what he did.
The mixture was a mystery, but it tasted delicious.
Pemberton took the mixture to a drug store.
The drug store sold the medicine as a drink for a few cents a glass.
Pemberton and a partner started a company to make and sell the drink.
However, the business didn't make much money.
Then a smart businessman named Asa Candler bought the company.
Candler made the business much more successful.
The company grew and it sold the drink around the world.
What happened to the mysterious headache cure?
It's now a global product.
It's one of the most famous brands in the world, Coca-Cola.
The Coca-Cola company markets the drink in 200 countries.
It sells more than 1.6 billion drinks every day.
An accident with a candy bar became another business idea in the United States.
It happened in 1946.
Percy Spencer, an engineer, put a candy bar in his jacket pocket.
Then he went to work.
That day he was testing a magnetron in his company's laboratory.
The company used magnetrons to make radar systems.
A magnetron is a device that produces microwaves.
These are short waves of energy that cause things to heat up.
Spencer stood near the magnetron.
He turned it on.
Suddenly, something very strange happened.
The candy bar in his pocket melted.
Spencer thought, maybe I could try this with other foods.
First, he put little pieces of dried corn near the magnetron.
Soft white puffy popcorn flew all around the room.
Then he put an egg next to the magnetron.
It heated up quickly and exploded.
Spencer got hot yellow egg yolk all over his face.
Some of Spencer's experiments were messy, but he discovered a new way to cook.
What did he invent?
The Microwave Oven.
The early microwave ovens were enormous.
They were about 5.5 feet, 1.7 meters tall.
And they weighed over 750 pounds, 340 kilograms.
They cost about $5,000 each.
They were only good for restaurant use.
Today, manufacturers make small, lightweight microwave ovens that are much cheaper than
the early ones.
These days, over 80% of homes in the developed world have a microwave oven.
Coca-Cola and the microwave oven were lucky accidents.
There are other examples too.
Did you know that the invention of plastic was an accident?
The Post-it note is another example.
Now people use millions of these small, sticky pieces of paper in offices and homes around
the world.
Will other accidents bring us successful business ideas in the future?
Who knows?
The lucky scientific accident is happening somewhere in the world right now.

8. Maybe studying music can help people math.
9. The children took piano and also studied fractions.
10. School children in the United States can't understand fractions until they are 11 years old.
11. More than middle school and high school students took a math test.
12. The musicians much better on the test.
13. Again, the study showed that the students who studied music scored almost points higher on the math section of the test.
14. Scientists continue to study the between math and music.
15. To your work in math, try studying music.
This is the audio script:
Eight middle school students recently won a math competition in Los Angeles, California.
The winners share a skill with California's most successful engineers.
Can you guess what it is?
According to a 1989 study,
the best engineers in the Silicon Valley play musical instruments.
This is true for the math students, too.
Is this a coincidence?
Some scientists don't think so.
They think there are good reasons.
Think about the similarities between math and music.
First, they both use sequences and patterns.
In this sequence of numbers, 5, 8, 11, 14, 17,
do you see the pattern?
In other words, can you guess what number goes next?
Now, think of some music you like to listen to.
Every piece of music is a sequence of musical notes.
When you listen to the music, do you hear any parts repeat?
The repeating parts form a pattern in the sequence of notes.
What's special about the organization of music?
It's mathematical.
Every piece of music is divided into small equal parts called measures.
Each measure has a certain number of beats.
A beat can be a whole beat or a part of a beat,
such as one half of a beat, one quarter of a beat,
or one eighth of a beat.
The parts of a beat are like mathematical fractions.
Scientists studied the similarities between math and music.
They learned that both musicians and mathematicians
think about patterns and sequences at the same time.
This gave the scientists an idea.
Maybe studying music can help people understand math.
They did research to learn more.
One researcher looked at seven-year-old children.
The children took piano lessons and also studied fractions.
Surprisingly, they understood the fractions.
This was unusual.
School children in the United States normally can't understand fractions
until they are 11 years old.
Maybe the piano lessons help the children think like mathematicians.
The U.S. Department of Education did another study.
More than 25,000 middle school and high school students took a math test.
Half of the students played a musical instrument and half did not.
The musicians did much better on the test.
Other researchers looked at the SAT scores of high school juniors and seniors.
Some students studied music and others did not.
Again, the study showed that the students who studied music
scored almost 45 points higher on the math section of the test.
Scientists continue to study the connections between math and music.
They certainly don't have all the answers, but they do have a suggestion.
To improve your work in math, try studying music.

10. It's always the same for all the features on a beautiful or face.
11. When the doctor put the mask over pictures of beautiful faces, the faces all the mask perfectly.
12. Is beauty the all over the world?
13. When the mask is put over pictures of people from many different , the ratio still works.
14. Other surgeons learned about Dr. Markhart's important .
15. Cosmetic surgeons can also use it to help people more beautiful.
This is the audio script:
What makes a face beautiful?
Is it the size and shape of the mouth, nose and eyes?
Is it the shape of the face?
Is beauty different for men and women, or for people from different cultures?
We all know a beautiful face when we see one.
What creates that physical beauty?
Dr. Stephen Markhart has an answer.
He says that beauty is mathematical.
Dr. Markhart is a surgeon from California.
His patients are people with deformed faces.
Some of his patients can't eat or breathe easily because their noses or mouths don't
function normally.
Dr. Markhart does plastic surgery to correct these problems.
Some patients' problems were very difficult to fix.
Dr. Markhart needed some guidelines to help him be successful.
So he started to do research.
He wanted to know why some faces are beautiful.
What did he find?
He found that beauty is not a mystery at all.
It's just a simple ratio.
The ratio that defines beauty is 1 to 1.618.
The ratio, 1 to 1.618, shows the relationship between different features on a beautiful face.
For example, when a face is beautiful, the mouth is 1.618 times wider than the nose.
The width of the nose is 1.618 times the width of the tip of the nose.
The ratio is even true for teeth.
The width of the two front teeth is 1.618 times wider than the height of one of the teeth.
What about the measurements of other features, such as the chin and the mouth, or the eyes
and the nose?
The ratio never changes.
It's always the same for all the features on a beautiful or handsome face.
Dr. Markhart used the ratio to make a mask.
The mask has many lines and geometric shapes.
When the doctor put the mask over pictures of beautiful faces, the faces all fit the mask perfectly.
Then he put the mask on less beautiful faces.
These faces didn't fit the mask.
Is beauty the same all over the world?
Yes.
When the mask is put over pictures of people from many different places, the ratio still works.
Beautiful faces from Africa, Asia, Europe, and North and South America all fit the same mask.
Other surgeons learned about Dr. Markhart's important findings.
Plastic surgeons can use the ratio to repair deformed faces and help people live healthier lives.
Cosmetic surgeons can also use it to help make people more beautiful.
Would you like to try Dr. Markhart's mask?
Does your face have the geometry of beauty?
You can find out the mask is online.

14. Today, on the base of the Eiffel Tower, there are names of brilliant French scientists and mathematicians.
15. However, there's one important name that's , Sophie Jean-Man.
This is the audio script:
Imagine telling Einstein to stop studying physics.
Imagine telling Picasso to stop painting.
Could they stop doing the things they loved?
This is what people try to do to Sophie's or Matt.
Sophie's love was mathematics.
She fell in love with it when she was only 13 years old.
She found a book about Archimedes and his love of geometry in her father's library.
Then, she read all the books about math she could find and decided to become a mathematician.
There were two problems.
First, Sophie was born in 18th century France.
Second, Sophie was a girl from a middle-class family.
It was very unusual for girls from the middle-class to study math in the early 18th century in
France.
Sophie's parents wanted her to be like other girls.
When she studied math, they tried to stop her.
Sophie didn't want to stop.
She studied secretly at night by candlelight when her parents slept.
Sophie's parents found out and they took away her candles.
That didn't stop Sophie.
She found more candles.
Finally, her parents decided to let Sophie study.
It was too hard to stop her.
When Sophie was 18 years old, a school for mathematicians opened in Paris.
She couldn't take classes there because it was for men only.
However, she didn't let this discrimination against women stop her.
She started writing letters to math professors at the school.
She asked them questions and she wrote about her ideas.
However, she didn't sign her own name on the letters.
She used a man's name, Monsieur Le Blon, a student at the school at
one time.
This idea worked and the professor responded to her letters.
After a while, one professor asked to meet the brilliant Monsieur Le Blon.
Imagine his surprise.
Monsieur Le Blon was a woman.
The professor didn't tell anyone.
He kept Sophie's secret.
Sophie continued to write to other mathematicians.
She always signed her letters, Monsieur Le Blon.
She met some of these experts, but they usually stopped helping her after a short time.
Was it because she was a woman?
No one is sure.
However, we do know one thing.
There was strong prejudice against educated women in Sophie's time.
This created a difficult challenge, but it didn't stop her.
Sophie continued to study.
She taught herself other kinds of math, such as algebra and calculus.
She is famous for her excellent work on a difficult math problem that was a challenge
for many other mathematicians.
Sophie is also famous for her studies of metal as a building material.
Years later, engineers used her ideas to build skyscrapers, such as the Eiffel Tower
in Paris, Sophie's hometown.
Today, on the base of the Eiffel Tower, there are 72 names of brilliant French scientists
and mathematicians.
These people all made great contributions to the world.
However, there's one important name that's missing, Sophie Jean-Man.

Sean L. wanted to give his wife a big surprise.
He went online and bought a diamond ring for her.
Two hours later, his wife texted him, who's the ring for?
Sean was very surprised.
He was angry too.
How did she know about the ring?
She wasn't the only one.
In fact, all of his Facebook friends received the same news.
Sean L. bought a gold diamond ring from overstock.com.
In Shanghai, China, a young couple said goodbye in a subway station.
They kissed for a long time.
They didn't see anyone, but someone saw them.
Their private kisses became very public.
Soon, millions of people all over the world also saw them kissing on the Internet.
Allison C. 15 was out with a group of people in Dallas, Texas.
One member of the group took a picture of her.
A few months later, her photo appeared in an advertisement in Australia.
How did these private acts become public?
Sean was a member of Facebook.
Facebook is a website where people can meet other people and communicate with their friends
and family.
Facebook used a program called Beacon to track Sean's online purchases.
Then Beacon posted the news for his Facebook friends.
In Shanghai, a security video camera was taping the subway station.
Guards were watching the monitor, and they focused on the couple.
Then one of the guards uploaded the video to a video sharing site.
In Dallas, the person who took Allison's photo uploaded his pictures on Flickr.
Flickr is a photo sharing site with more than a billion photos.
A company in Australia saw the photo of Allison and used it in an advertisement.
No one told Allison or asked her permission.
How did she find out?
On Flickr, of course.
That's where she saw a photo of the ad.
Is there anything you can do when you lose your privacy on the Internet?
Some people complain.
For example, over 50,000 Facebook users complained about Beacon.
They said, Facebook is posting our private information without our permission.
Facebook stopped using Beacon in this way.
In many countries, people have a legal right to privacy.
When they lose their privacy, they can sue.
Sean joined other Facebook users to sue Facebook.
The Chinese couple sued the Shanghai subway.
Allison's family sued the advertising company.
The Chinese subway company acted quickly.
It fired the guards, apologized publicly, and offered the couple compensation.
The couple accepted the money.
The other two cases are going to take more time.
Sean and Allison may win in the end, but it's already too late.
They lost their privacy with just one quick click.
This is the end of the audio program.
