  • Black and white photograph of a rocket-like object on its side in an industrial area. Caption: Sputnik heads for the launchpad,

    Welcome to the decade of Rock 'n Roll, drive-ins and McCarthyism. An America flush with cash and terrified of the "Red Menace" defines the inventions of the 1950s. Featured inventions include: the transistor radio, Sputnik, the flight data recorder, the Breath-a-Lyzer, and the hovercraft.

  • Multiple images showing a progression of yellow to red circles appearing on a dark background. Caption: Then, a series of images are collected at regular intervals.

    Radioactivity is all around us and comes from a variety of sources. There are three types of radiation, and experiments show the differences in the penetrating power of each one. A major use of radioactivity is in nuclear medicine. Discusses the half-life of radiation and how to calculate it.

  • Irregular orange and yellow shapes in greenish clouds. Caption: should focus on physics, math, and computer science.

    The Atacama large Millimeter/Sub-millimeter Array, or ALMA, is a vast array of radio telescopes and the most powerful observatory of its kind. ALMA is stationed in the Atacama Desert of Chile which is one of the world’s best sites for observational astronomy because of the high altitude, nearly non-existent cloud cover, dry air and lack of light pollution and radio interference due to the small populations. ALMA peers into previously hidden regions of space with unprecedented sharpness and sensitivity.

  • Closeup of a circuit board. Caption: which is controlled by the circuit board.

    Investigates some of the key concepts of physics. Using a drum kit, we look at how sound works, how we make it, and how it gets around. Also, examines electricity and electromagnetism and notes the similarities between a remote control car and a mobile phone charger. Finally, takes a look at radioactivity and identifies a radioactive device that can be found in almost every family home.

  • Black and white photograph of an early plane with a person standing next to it. Caption: That first motorized flight lasts only 12 seconds,

    The decade that kicked off the 20th Century was responsible for two inventions that helped define the next 100 years. The airplane and the radio set the planet on a course to becoming truly a global village. Featured inventions include: the radio, the airplane, the disposable razor, the air conditioner, and the vacuum cleaner.

  • Irregularly shaped gaseous shape with bright stars glowing around and behind it. Caption: with the potential to explore our universe

    Visible light, which can be seen with human eyes, comprises a small sliver of the electromagnetic spectrum. The rest of the spectrum, from short wavelength gamma rays to long-wavelength radio waves, requires special instruments to detect. ALMA uses an array of radio telescopes to detect and study radio waves from space. ALMA is an advanced tool for studying very old stars and galaxies. These objects now are seen at great cosmic distances, with most of their light stretched out to millimeter and sub-millimeter wavelengths by the expansion of the universe. ALMA provides the unprecedented ability to study the processes of star and planet formation.

  • Two people in lab coats. Caption: His electrode is doing exactly the job it's supposed to.

    The last decade of the 20th Century sets us on course for the next 100 years. With inventions like Global Positioning Satellites and The Hubble Space Telescope, the inventions of the 1990s help us see where we've been and where we're going. Additional inventions include: the wind up radio, camera phone, the Mars Pathfinder, and the neurotropic electrode.

  • An electromagnetic spectrum is superimposed on the image of a galaxy. The visible spectrum is highlighted. Caption: A radio wave is a part of the electromagnetic spectrum,

    The Very Large Array, or VLA, is a complex of 27 massive antennas on the Plains of San Agustin in central New Mexico, all pointing skyward to monitor radio emissions from the cosmos. With support from the National Science Foundation, astronomers use this facility to observe the most dynamic, cataclysmic events in the universe. Part of the "Science Nation" series.

  • Black and white close up photo of a man's face. Caption: had become fascinated by the potential of radio waves.

    Today, people send emails, text messages, and status updates instantaneously. But not so long ago, messages were handwritten and travelled no faster than people could carry them. With the invention of the telegraph and then the telephone, instant communication was born. Radio and television created an industry for mass entertainment that continues to grow, and the computer age changed how data is crunched. With the invention of the internet in the 1980s, the world of communication has truly shrunk.

  • Brown spotted lizard on a tree trunk. Caption: He plans to radio track the lizards.

    Anole lizards are highly territorial and typically stick close to their home tree. So, what happens when a team of researchers carries them far away into the forest? Will they find their way back? Dr. Manuel Leal and colleagues designed an experiment to find out. They displaced the lizards from their home territories and then tracked their movements using radio transmitters. Most of the lizards were able to orient themselves and head in the right direction, with some making a beeline back to their original tree in less than 24 hours.
