Video summary

This animated film compares the lives of Ada Lovelace and Alan Turing, two mathematicians from different eras whose bold and creative ideas helped develop the first computers.

Born in 1815, Ada was encouraged by her family at a young age to study mathematics.

She met inventor Charles Babbage, who told her about an idea he had for a 鈥榗alculating鈥 machine: a large contraption that could do complicated sums. Ada immediately saw the potential in the machine and wrote groundbreaking ideas about it.

Alan Turing, born nearly a century later in 1912, imagined an electrical machine that could store information, like a 鈥榤emory鈥, which could therefore do more complicated work than other machines. His ideas shaped the development of the first electrical computers, which became instrumental during World War II for deciphering German codes.

Both Alan Turing and Ada Lovelace understood the potential of computers before they were even built. Through their creativity and forward-thinking, they imagined and shaped the technology we have today.

Teacher Notes

Themes in the film include:

  • Technological advances
  • Significant individuals who have shaped the technology we use and how we communicate

Additional Notes

  • The Importance of Ada鈥檚 Family

It was unusual for women to be able to study mathematics at that time. Women's access to formal education was limited, especially in scientific and mathematical fields.

There was very little choice of job at the time for women and the majority involved long hours of physical work, low wages and very little emphasis on education or development.

Ada鈥檚 ability to study and contribute to mathematics was exceptional and made possible by both her privileged background, which meant she didn鈥檛 need to work, and her supportive family, who encouraged her education and creative pursuits.

  • Ada showed it could work with 鈥渨ords and music鈥

Ada wrote about Babbage鈥檚 machine, explaining how the machine could be developed to handle complex patterns. And not just numbers - it could even work with other types of information, like words and music.

She saw the potential in early computing over a century before the technology existed, including the fact we would use computers to read, write and develop creative works. She left instructions for this future machine and, once computers existed, the instructions worked! Because of this, she鈥檚 often called the world's first 鈥榗omputer programmer鈥.

Before the video

Establish what they know about computers and show them a few photographs of old computers: Alan Turing鈥檚 large WW2 decoding computer, a 1980s desktop computer, a laptop and a new mobile phone

  • Which of these do you think is biggest?
  • What do you think it does? What sound does it make? How do you think people use it?

Ask them to guess what order they were invented in.

Explain four bits of key vocabulary they鈥檒l be hearing:

  • Inventor
  • Computer program
  • Mathematician
  • Technology

During the video

00:48 - What did Charles Babbage want his machine to do? (Solve difficult mathematical sums, like a calculator does)
01:30 - What did Ada write that was important? (She wrote instructions for the future machine, even though it wasn鈥檛 finished)
02:08 - What special thing did Alan鈥檚 machine have? (It has a kind of 鈥榤emory鈥 using electricity, so it can store a lot of information.)
02:52 - What machine did Alan use to unscramble codes? (Computers. They were a new invention that Alan helped create, which could do a lot of calculations quickly)
03:18 - Why were Ada and Alan amazing? (They understood lots about computers before they had been made, because they were imaginative)

After the video

  • Who was born first, Alan or Ada?
  • What do we use to power computers today? How was Ada鈥檚 machine powered? How was Alan鈥檚 computer powered?
  • What made Ada different to other women who lived at the same time as she did?
  • Why couldn't Ada Lovelace test her ideas for the machine?
  • What was based on Alan Turing鈥檚 design?
  • How did humans use computers to help them in WW2?
  • Is there anything that Ada imagined that came true?
  • What did Alan predict would happen in the future? Was he correct?

Return to the photographs of the different computers and ask if they can put them in chronological order of when they were created, using clues from the film. Emphasise how smaller they鈥檝e got as the technology has improved.

Ask them to draw what type of computer they think might come next, or which they would like to use in the future.
