This decade is best remembered for disco and Watergate. But the inventions in the 1970s mark the beginning of the digital age to come. Featured inventions include: cell phones, the bomb disposal robot, Post It Note, hybrid cars, and digital cameras.

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.
What is the information "superhighway" really all about? Communications engineers at GTE and US WEST provide a remarkably clear introduction to the basic concepts of the digital communications revolution. Demonstrates how 1s and 0s represent graphics, video, and even sounds.
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.
Go into any grocery store and cameras may be watching you. These cameras are not looking for thieves, they’re looking for shoppers. The cameras are focused on the tops of peoples’ heads (so it’s anonymous), but they don’t have to see faces to track which store aisles get the most traffic and how long consumers spend looking over products. With support from the National Science Foundation, computer scientist and CEO of VideoMining Rajeev Sharma and his team have designed software that automatically generates statistics about in-store shopping behavior. These statistics can provide valuable insights for supporting critical decisions in store layout design, merchandising, marketing, and customer service. Sharma’s team has developed similar technology to help caregivers monitor the elderly.
The world's largest digital camera is currently being assembled at a warehouse in California, and host Dianna Cowern is there for the revealing of the lenses for this camera. These lenses will go on the Large Synoptic Survey Telescope, which will conduct a giant sky survey by taking panorama photos. Part of the "Physics Girl" series.
The Carboniferous rainforest collapse set the stage for a takeover that would be a crucial turning point in the history of terrestrial animal life. If it weren’t for this event in ancient history, human ancestors might never have made it out of the swamps. Part of the “Eons” series.
The fossils of bats resemble the bat of today with some differences related to leg length and location of claws. Their fossils are also found on all the continents except Antarctica, and they appear in these areas around the same time. So what are the origins of bats? Part of the "Eons" series.
Before the start of the Eocene Epoch about 56 million years ago, Antarctica was still joined to both Australia and South America. During this time, Antartica was without ice and snow. Fossil records indicate it was covered in green foliage. Part of the "Eons" series.
In October 2004, the understanding of the human family tree was turned upside down. Anthropologists reported that they had discovered the bones of a tiny, unknown hominin, on the Indonesian island of Flores. It was named Homo floresiensis, but it's often called "the hobbit" for its short stature and oddly proportioned feet. It’s been at the center of a major controversy in the field ever since. Part of the "Eons" series.
Synapsids were the world’s first-ever terrestrial megafauna, but the vast majority of these giants were doomed to extinction. However, some lived on, keeping a low profile among the dinosaurs. Part of the “Eons” series.
Megaloceros was one of the largest members of the deer family ever to walk the Earth. The archaeological record is full of evidence that human ancestors lived alongside and interacted with these giant mammals for millennia. Part of the “Eons” series.
The climate of the Sahara was completely different thousands of years ago. Rock art from the region reveals a climate that was wet and covered with plants. Scientists have collected data that supports the notion that the ancient climate of the area enabled animals and humans to live in the middle of the Sahara. Part of the "Eons" series.
The story of the egg spans millions of years from the first vertebrates that dared to venture onto land to today’s mammals. This episode takes an in-depth look at the biology and history of oviparous and viviparous animals. Part of the "Eons" series.
In this episode, host Dianna Cowern experiments with straws and water to discuss convex and concave lenses. Is it possible to create a lens in a straw? Part of the "Physics Girl" series.
Paleontologists have spent the better part of two decades debating whether Coelophysis ate its own kind. It turns out, the evidence that scientists have had to study in order to answer that question includes some of the strangest and grossest fossils that any expert would ever get to see. Part of the "Eons" series.
The myth of the missing link is persistent and argues that there must be a specimen that partly resembles an ape but also partly resembles a modern human. However, the reality is that there is no missing link in the human lineage because that’s not how evolution works. Part of the "Eons" series.
When pterosaurs first took flight, it may have marked the beginning of the end for the winged reptiles. Some evidence gathered suggests that the power of flight led to evolutionary changes in the reptiles, which may have ultimately led to their downfall. Part of the "Eons" series.
Just a few thousand years ago, the island of Madagascar was inhabited by giant lemurs. How did such a diverse group of primates evolve in the first place, and how did they help shape the unique environments of Madagascar? Part of the "Eons" series.
A 9,500-year-old burial in Cyprus represents some of the oldest known evidence of the early relationship between humans and cats. But when did this close relationship between humans and cats start? Part of the "Eons" series.
