It was a decade of big bands and big bangs. During the Second World War, the 1940s bring some of the greatest inventions of all time. And in the peaceful years that followed, all that inventing know-how would carry on in ways never imagined. Featured inventions include: the jet engine, the computer, the microwave oven, kitty litter, and the Crash Test Dummy.

When Genoveva opens her magic book, the screen is filled with feathers, beaks, horns, legs, wings, and snouts. Genoveva's magic book transports her to various habitats where she learns about the animals that live there. Proud of its soft song and its brick-colored feathers, this bird builds its home with mud. In this episode, Genoveva travels with her magic book and flies all over the world with this little bird.
The scientists will explore the color spectrum and explain why humans cannot see the whole spectrum. They will also create a solar oven using aluminum foil. Part of the House of Science Series.
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.”
Students investigate the features of vibrations and waves. Examples of these phenomena help students understand how sounds are formed, how light travels, and how ocean waves move. Students also explore different types of waves such as microwaves, radio waves, and seismic waves. Concepts and terminology include vibration, energy, wave, light, and sound.
In this episode, host Dianna Cowern explores one of the most mysterious discoveries in physics from the 1960's: a constant microwave signal that seemed to be coming from everywhere in the universe. It turned out to be light from an unusual process 13.8 billion years ago and originated from the beginning of the universe. Part of the "Physics Girl" series.
Meteorologists studying clouds in Europe are learning about the microphysical processes that occur naturally in clouds. This knowledge helps researchers gain new fundamental knowledge that can help improve weather and climate forecast models. Students will discover how scientists study cloud formation by generating artificial clouds in a laboratory. Scientists research how clouds originate and how they react to surrounding natural elements. They will reveal how microwave radiometers, lasers, and satellites are used in researching cloud development.
Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom and magnification feature, so zoom in for a closer look, if you need to.

From a table at a bar, on a corner of the city of Buenos Aires, we discovered the nature of some of the “wave motion phenomenon” that surrounds us. Some of these were radio and TV waves or the ones from the microwave in the kitchen, solar light, X-rays and cosmic waves.
