Explores how studying the atom forced us to rethink the nature of reality itself, encounters ideas that seem like they're from science fiction but in fact are a central part of modern science, and discovers there might be parallel universes in which different versions of us exist and finds out that empty space isn't empty at all, but seething with activity. The world we think we know, the solid, reassuring world of our senses, turns out to be a tiny sliver of an infinitely weirder and more wonderful universe than we had ever conceived of in our wildest fantasies.

Matthew Schneps is a researcher at Harvard University with a doctorate in physics from the Massachusetts Institute of Technology (MIT). He also happens to have dyslexia, so reading has always been a challenge for him. That is, until he got a smartphone. Schneps soon found that for him, a smartphone was easier to read than a paper or a book. But, was it just him? Or, had he stumbled onto something that could help others with dyslexia? Part of the National Science Foundation Series “Science Nation.”
When the Maori arrived to New Zealand in 900 AD, it was one of the last places to be settled on earth by humans. They brought many elements of their Polynesian culture to the Islands, but none transformed the landscape as much as their use of fire. Modern Maori scholars shed light on the important role that fire has always played in their lives, as well as the inherent sense of conservation that is embedded in their culture and approach to the land. Part of WildFIRE PIRE series.
As scientists delved deep into the atom, into the very heart of matter, they unraveled nature's most shocking secrets. They had to abandon everything they believed in and create a whole new science, which today underpins the whole of physics, chemistry, biology, and maybe even life itself. Tells a story of great geniuses, like Albert Einstein and Werner Heisenberg who were driven by their thirst for knowledge and glory. It's a story of false starts and conflicts, ambition, and revelation, a story which leads us through some of the most exciting and exhilarating ideas ever conceived of by the human race.

Timeblazers Sam and Jen meet some geniuses of the past, including Nicholas Copernicus, the first to map out the Solar System; William Shakespeare and his magnificent Globe Theatre; Benjamin Franklin, a great inventor, printer, and philosopher; Thomas Edison, who invented the first practical incandescent light bulb; Eratosthenes, who used a stick to figure out the size of the earth and that the planet was round; Plato, a great philosopher and thinker; Jean-Francois Champollion, who unlocked the mystery of the Rosetta Stone; Magellan, who was the first to sail around the world; and the "Renaissance Man," Leonardo da Vinci.
The rate of a chemical reaction is affected by a number of factors, including temperature and the concentration of reactants at the beginning of the reaction. While the chemical equation may show reactants turning into products as a straightforward process, it is actually involved and precise. How exactly do reactants turn into products? Sometimes, the answer is as simple as two atoms bumping into each other and forming a bond. Most of the time, however, the process is much more complex. Controlling the rate of reactions has implications for a variety of applications, including drug design and corrosion prevention. Part of the series Chemistry: Challenges And Solutions.
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!
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The kids arrive at a planet where only two elderly people are left. The rest of the population left because their sun is dying. Maqui explains to them that the sun is a star, and she teaches the life cycle of stars. The kids rescue the elderly pair and reunite them with the rest of their planet’s inhabitants. During this adventure, they learn the difference between planets and stars.
Technetium is a chemical element with the symbol Tc and atomic number 43. It is the lightest element whose isotopes are all radioactive, none of which is stable other than the fully ionized state of ⁹⁷Tc.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko thinks that somewhere lies a creature that blows so hard that it makes the boughs of trees quiver and creates the desert dunes. He believes that the clouds flee before the wind comes because they are afraid of the creature. He decides to go look for it. Tired after walking beneath the hot sun, a fresh, light breeze makes his rest more pleasant. However, the creature is actually the Harmattan blowing over West Africa.
While Earth's weather reports center on precipitation, temperature, wind direction, and humidity, space weather forecasts attempt to predict activity that occurs on the sun. Scientists also study how the weather on the sun will affect Earth. At the University of Michigan a team studies solar storms as they form and then barrel off the sun. Sometimes these storms hit the Earth with damaging force. Space weather has the potential to interfere with everything from satellite communications to electrical power. This team is aiming for a five-day forecast capability to give government, private industry, satellite operators, and power grid companies more time to take necessary action to protect critical infrastructure.

Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas.
The 1960s world population has nearly doubled and now tops 7 billion. Population growth, though little discussed, is putting an unprecedented burden on the planet's life systems. Brings to light the connection between overpopulation and our most pressing environmental and humanitarian problems, as well as the solutions. Also, follows Beth, an American mother and child rights advocate, who grew up in a large family of 12 as she travels to Africa to witness first-hand the impact of population growth in the developing world and its role in exacerbating poverty. While there, she meets a young Ethiopian woman, Zinet, who comes from a poor family of 12, but has found the courage to break free from long-held cultural barriers holding back women. Features a broader discussion of the solutions to overpopulation in both the developed and developing world.
Man-made debris threatens wildlife's reign over a Hawaiian archipelago. Segment of video from Wild Chronicles Series.
For as long as parents and babies have been smiling, laughing, and cooing at each other, scientists still have a lot of questions about just how these interactions help infants develop. With support from the National Science Foundation, University of Miami psychology professor Daniel Messinger and his colleagues want to learn more about child development by studying how moms, dads, and babies respond to each other. Part of the National Science Foundation Series “Science Nation.”
Students explore the many important uses of electricity. The nature of electricity and the formation of electric current are highlighted. Special attention is given to safety and electricity. Concepts and terminology include charge, current, lightning, battery, generator, and wiring.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko wonders why the moon changes shape so often. Sometimes, when he sees the moon rising in the distance like the sun, he thinks that by walking towards the horizon he could get closer and find out more. That way he could even ask the moon itself. During his long walk towards the ever-receding horizon, Moko watches the moon constantly changing shape. Sometimes it's a crescent like a smile, sometimes a disc of light; sometimes it's white, sometimes yellowish. It travels across the sky but you can't see it moving. One night, Moko decides to watch the moon perform its lovely dance among the stars. He figures he'll never reach the horizon, and in fact maybe the moon just wants to put on a show, to be watched more often.
With support from the National Science Foundation, mechanical and computer engineer Nilanjan Sarkar and psychologist Zachary Warren at Vanderbilt University have developed a learning environment for kids with autism, built around state-of-the-art technologies. One of those state-of-the-art technologies is a humanoid robot, nicknamed Russell, who works with the children on their ability to imitate others. The robot has some of the characteristics of a human, but it’s not as complex, so it doesn’t overstimulate or overwhelm a child with autism.
Scientist William Rowan is renowned for his research on the dark-eyed junco. Before Rowan, it was unknown what environmental cues animals used to time the seasonal changes in their biology. Through a groundbreaking experiment with the junco, Rowan discovered the physiological reaction of organisms to the length of day or night. Shot as an historical re-enactment, this segment provides a glimpse into the history and human dimensions of scientific research and reveals one of the first studies that made juncos well-known to biologists. Part of Ordinary Extraordinary Junco (Chapter 1).
