• 1:00
  Which American inventor improved the practical electric light
• 1:03
  bulb and created the phonograph? The answer is Thomas Edison.
• 1:13
  He led teams that tested thousands of materials to make
• 1:16
  long lasting filaments and built systems for electricity in homes
• 1:20
  and streets. His phonograph could record and
• 1:23
  play back sound, which was a brand new idea in his time.
• 1:27
  Question two, who invented the telephone and made the first
• 1:31
  successful call in 1876. The answer is Alexander Graham
• 1:40
  Bell. He experimented with sound and
• 1:43
  electricity and sent a message that turned vibrations into
• 1:46
  speech. His work opened the door to long
• 1:49
  distance communication that people soon used in daily life.
• 1:53
  Question 3. Which scientists discovered
• 1:56
  radioactivity and won Nobel Prizes in both physics and
• 2:00
  chemistry? The answer is Marie Curie.
• 2:07
  She and her husband Pierre studied uranium and discovered
• 2:11
  new elements, polonium and radium.
• 2:14
  Marie Curie's careful research changed science and medicine by
• 2:18
  helping people understand how atoms give off energy.
• 2:21
  Question four. Who designed the movable type
• 2:24
  printing press in Europe around 1450, making books faster and
• 2:29
  cheaper to produce? The answer is Johannes
• 2:36
  Gutenberg. His press used metal letters
• 2:39
  that could be rearranged so printers did not have to carve a
• 2:42
  full page every time. Printing spread ideas quickly
• 2:46
  and helped more people learn to read.
• 2:48
  Question 5. Which engineer championed
• 2:51
  alternating current, designed the induction motor, and worked
• 2:55
  on wireless power experiments? The answer is Nikola Tesla.
• 3:03
  His AC systems made it possible to send electricity over long
• 3:07
  distances efficiently. The induction motor he designed
• 3:11
  is used in many machines, from household appliances to
• 3:15
  industrial equipment. Question six.
• 3:17
  Who wrote an early computer algorithm in the 1840s and is
• 3:22
  often called the first computer programmer?
• 3:28
  The answer is Ada Lovelace. She described how Charles
• 3:32
  Babbage's Analytical Engine could process symbols and
• 3:35
  numbers using a set of instructions.
• 3:38
  Her notes explained loops and operations that modern
• 3:41
  programmers still recognize today.
• 3:44
  Question 7. Which British computer scientist
• 3:47
  created the World Wide Web in 1989 linking pages with
• 3:51
  hyperlinks? The answer is Tim Bernerslee.
• 3:59
  He built the first web server and browser so researchers could
• 4:03
  share documents easily. The web quickly grew into a
• 4:06
  global system for information, learning and communication.
• 4:11
  Question eight, Who invented a three position traffic signal in
• 4:15
  the early 1900s that added a warning phase for safety?
• 4:23
  The answer is Garrett Morgan. His design helped drivers know
• 4:27
  when to stop and when to proceed, which reduced accidents
• 4:30
  at busy intersections. He also created a safety hood
• 4:34
  that helped people breathe more easily in smoky conditions.
• 4:38
  Question 9. Which chemist invented Kevlar, a
• 4:42
  strong and lightweight fiber used in helmets, sports
• 4:45
  equipment, and cables? The answer is Stephanie Kwolak.
• 4:53
  She discovered the material while developing new polymers
• 4:57
  and noticed that a thin solution formed surprisingly tough
• 5:00
  fibers. Kevlar's strength to weight
• 5:02
  ratio makes it useful in many safety and industrial products.
• 5:07
  Question 10. Who imagined flying machines,
• 5:11
  parachutes, and mechanical devices in detailed notebooks
• 5:15
  during the Renaissance? The answer is Leonardo da Vinci.
• 5:23
  He observed birds, water, and gears, then turned those
• 5:27
  observations into careful sketches and models.
• 5:31
  Many of his designs showed how machines could use energy,
• 5:34
  motion, and balance in new ways. Question 11.
• 5:39
  Which inventor created the first practical windshield wiper after
• 5:43
  noticing drivers could not see clearly in rain and snow?
• 5:51
  The answer is Mary Anderson. Her hand operated lever moved a
• 5:55
  rubber blade across the glass to Clearwater and slush.
• 5:59
  The car makers later adopted automatic versions and
• 6:03
  windshield wipers became standard on vehicles.
• 6:06
  Question 12 Who invented a lubrication device that kept
• 6:10
  train engines running smoothly and reliably, inspiring the
• 6:14
  phrase asking for the real high quality version of something.
• 6:22
  The answer is Elijah McCoy. His automatic lubricator applied
• 6:26
  oil while machines were moving, which saved time and prevented
• 6:30
  damage. Railroads valued the dependable
• 6:33
  performance of his design. Question 13 Which actor and
• 6:38
  inventor Co created a frequency hopping system that helped
• 6:41
  protect radio signals from jamming?
• 6:48
  The answer is Hedy Lamarr working with composer George and
• 6:52
  Tile. Their idea used changing radio
• 6:55
  frequencies to keep a signal secure and steady.
• 6:58
  The concept helped inspire technologies used in modern
• 7:02
  wireless communication. Question 14 Who helped
• 7:06
  popularize crop rotation and found many practical uses for
• 7:09
  peanuts and sweet potatoes to support farming in the southern
• 7:12
  United States. The answer is George Washington
• 7:20
  Carver. He taught farmers how rotating
• 7:22
  crops could restore nutrients to soil, which improved harvests.
• 7:27
  His bulletins and demonstrations shared easy to follow steps for
• 7:30
  better farming. Question 15 Which computer
• 7:34
  scientists created the first widely used compiler and helped
• 7:37
  develop the COBOL programming language?
• 7:44
  The answer is Grace Hopper. A compiler translates human
• 7:48
  readable instructions into machine code, which made
• 7:51
  programming faster and less error prone.
• 7:54
  Her leadership shaped tools that businesses and governments used
• 7:58
  for large scale computing. Question 16 Who invented the
• 8:02
  first practical, affordable ballpoint pen that wrote
• 8:05
  smoothly and dried quickly on paper?
• 8:12
  The answer is Laszlo Biro. He used quick drying ink and a
• 8:16
  tiny rolling ball at the tip to deliver consistent lines without
• 8:20
  frequent smudges. His design became popular for
• 8:23
  everyday riding worldwide. Question 17 Which inventor
• 8:28
  created a bagless vacuum cleaner by using cyclonic separation to
• 8:32
  spin dust out of the air? The answer is James Dyson.
• 8:40
  He tested many prototypes to make strong, consistent suction
• 8:44
  without disposable bags. The design changed how home
• 8:48
  vacuum cleaners collect dust and dirt.
• 8:51
  Question 18. Who designed and built the first
• 8:54
  successful powered airplane in 19 O3 at Kitty Hawk, NC?
• 9:04
  The answer is the Wright brothers, Orville and Wilbur.
• 9:07
  They studied wing shapes, built their own wind tunnel, and
• 9:11
  practiced with gliders before attempting powered flight.
• 9:15
  Their Flyer combined a lightweight engine with a
• 9:17
  control system for pitch, roll and Yaw.
• 9:21
  Now it is time for the Super Challenge.
• 9:24
  Take a breath, think it through and go for it.
• 9:27
  Super Challenge Question What material created by Charles
• 9:31
  Goodyear in the 1800s transformed rubber into a
• 9:35
  tougher, more useful form for products like tires and shoe
• 9:39
  saws? The answer is vulcanized rubber.
• 9:46
  Charles Goodyear discovered that heating natural rubber with
• 9:49
  sulfur made it more durable and less sticky.
• 9:52
  This process allowed rubber products to keep their shape in
• 9:55
  hot and cold conditions, which led to many new tools and
• 10:00
  everyday items. Great job today you explored
• 10:08
  inventors who changed how people move, communicate, learn, and
• 10:13
  work. From engines and electricity to
• 10:16
  fibers and the web, each idea solved a real problem and LED to
• 10:20
  new possibilities. If you enjoyed this episode, try
• 10:24
