In an increasingly technological world, citizens have an obligation to manage gadgets and devices in the best possible way. What is a competent digital citizen? How does one become a competent digital citizen? This episode reveals the characteristics of a competent digital citizen.
In this episode, Mo Rocca explores a Medical MacGyver that makes health devices from toys, train spinning, computerized Smart Shopping Carts, and soda bottle lights.
Martin, a funny and curious artist, discusses the world of design. He explores the design elements of color and shape of things in everyday life. In this episode, Martin investigates the relationship between design and advances in different types of technology. Part of "The Shape of the World" series.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the important invention of the assembly line which grew from developments of the Industrial Revolution. Part of the Social Studies Video Vocab Series.
The 14th-18th centuries are notable periods in history that radically transformed scientific thought. Traditional understandings and worldviews faced major changes as new scientific discoveries challenged long held beliefs in science, philosophy, and society. This was a revolutionary time for scholars, artists, scientists, and philosophers. Part of the “Civilizations and Ideas” series.
For Umberto Eco books are a great invention that cannot be improved. However, throughout history, books have undergone technical changes that have altered their nature and the way we use them. Books have undergone a make-over with new technological advancements. Nerdo Cavernas discusses the Digital Book: its uses, its contributions, and much more.
Self-taught scientists and engineers, Wilbur and Orville Wright taught the world how to fly and are one of America’s greatest success stories. Their first successful flight, on North Carolina's Outer Banks, took place in December 1903. Next, they returned to Dayton, Ohio and continued to develop and test the world's first practical airplane.
The roaring '20s marked a decade of unprecedented prosperity. It's no wonder the inventions that defined the 1920s are all about entertainment and convenience. Motion picture and television are two of the greatest inventions since sliced bread - both of which were invented during this time. Other inventions featured include the rocket, the lie detector, and Einstein's refrigerator.
Gives a general introduction to microscopes, a device invented 400 years ago. Begins with a simple magnifying glass and moves to the optical, confocal, electron, scanning electron, and the scanning tunneling microscopes. Shows that each one "sees" with increasing detail. The microscope opens invisible worlds and aids scientists in improving ours.
Timeblazers Sam and Jen look back at the squalid ways of old. For thousands of years people dumped garbage wherever they liked; food scraps were simply tossed onto the floor; and, in medieval times, garbage and human waste went right into the castle moat. All that garbage attracted the rats, which, in turn, spread a terrible disease called The Plague, The Black Death, or the Bubonic Plague.
Great inventions exist in the world of audio and music: stereo, surround sound, and holophonics, all known as 3D sounds. Although holophonics can be confused with surround sound because it tries to create a surrounding with sounds from different sources, holophonics have a completely different system and are only emitted through a stereo system, which when used with headphones and creates a sense of three-dimensionality.
A key to building denser, stronger materials that won’t fail or fracture under extreme conditions is the manufacture of ultra-high temperature, or UHT, ceramics. UHT ceramics can withstand highly extreme conditions, such as the heat coming out of a rocket as its launching into space. Part of the National Science Foundation Series “Science Nation.”
In this episode, host Mo Rocca shows viewers the light bulb that levitates, discusses the petrol pumps that fueled the world, and reveals the best advice from past inventors. He also discusses new technological developments in pet care. Part of "The Henry Ford Innovation Nation With Mo Rocca" series.
This episode features stories on an innovative surf park in the North Wales countryside and an invention aimed at stopping police chases. Host Mo Rocca also highlights the history of flight starting with the Wright Brothers and finishing with the modern technologies of space. Part of "The Henry Ford Innovation Nation With Mo Rocca" series.
With support from the National Science Foundation, chemist Kent Kirshenbaum and his team at New York University are engineering molecules to mimic the shapes, structures, and functions of natural proteins. The ultimate goal of this biomimetic chemistry research is to develop a reliable way to build synthetic proteins that can be put to work at the industrial scale. Part of the "Science Nation" series.
Firefighters risk their lives every time they run into a burning building. But, new technology may soon be watching their backs, no matter how far they venture into the flames and smoke. With support from the National Science Foundation, TRX systems is developing a new sensor system that can track firefighters where GPS units often fail.
In this episode, Mo Rocca explores how teen inventors are out to stop distracted driving, and learns how Thomas Edison’s inventions are still making us look all look like slackers. Then, he explores the invasion of the drones and windmills the size of fleas that have the potential to revolutionize electric power.
The Timeblazers go on an adventure through the ages to see how inventions are born and how each one-big or small- has the potential to significantly alter the course of history. For example, if it hadn't been for the invention of the primitive "wheel," the locomotive wouldn't have been invented. And without the locomotives, highways, overpasses, underpasses, on ramps, off ramps, traffic lights, rules of the road, or brakes wouldn't have been invented!
Tired of the same old evening news? Researchers at Northwestern University are inventing ways to make the news a lot more interesting. With funding from the National Science Foundation, Scientists at Northwestern's Intelligent Information Laboratory are working on a project that creates customized newscasts, read by online avatars based on individual preferences. The program called News at Seven is a system that automatically generates a virtual news show.
Solar panels are becoming a familiar site in communities across the United States, but what about solar fuels? A solar fuel is produced from sunlight through artificial photosynthesis, mimicking what Mother Nature has been doing for billions of years. Many chemists and chemical engineers are working to make solar fuels a viable option in the future. Part of the National Science Foundation Series “Science Nation.”
