This episode of Century of Flight features the Air Show, originating after World War I as a way for air forces to gain support as independent branches of the military. Racing and aerobatics became popular soon after, and air shows provided a way for pilots to show off their skills and planes. Experience the evolution of the Air Show, from the vast Shuttleworth Collection to the formation flying stunts of the Red Arrows. See a Vickers Wellington Bomber...

Spectral Band Replication (SBR) is a novel method for compressing digital audio files making it possible for millions of people around the world to enjoy either higher quality sound or higher compression easily and affordably. SBR was conceived by the Swedish inventor Lars Liljeryd and turned into a real-world application by a team of engineers that included Kristofer Kjörling, Per Ekstrand and Fredrik Henn. Liljeryd’s ideas revolutionized an entire...

By the year 2050, cops and robbers won’t look anything like it did in the past. Host Joe Penna talks to designers who’ve created a robotic security guard. He’ll work with a Harvard scientist who has developed a softball sized set of eyes and ears that allow crime fighters to see danger long before it can hurt them. And polygraphs could become a thing of the past if we can scan brain waves to see if people are telling the truth, or not.

Host Emily Calandrelli speaks to experts who are learning everything they can about asteroids and their potential impact on earth.

Follow our expert, high-profile panel of judges as they pick, rank and comment on THE GREATEST EVER‘s top ten tanks of all time; the ones that take you to the edge of armored experience and push the metal to the limit. Our team puts their picks through the paces, testing out their claims: we race a tank with a Volvo over 400 meters of rugged winter terrain and let a rock star take one out for a muddy ride. Our well-known, eclectic panel then debates,...

In this episode, we look at the ways robotic engineers are mimicking the natural world. BionicWheelBot and the BionicFlyingFox have been developed to navigate difficult terrain, like their biological counterparts. Robots like the canine-inspired models produced by Boston Dynamic are already being used in hazardousenvironments to reduce the need for humans to be exposed to risk. We’ll also see how robots are covering new ground in space exploration,...

Technology in sport has come along a long way, from the simplest timing devices such as stopwatches, to advances in fabric, and nutritional information, allowing athletes to compete and train in comfort, as well as to their optimum level of fitness. This video examines developments in swimsuit technology that have meant that Olympic swimmers get the benefit of slimmer, more hydrodynamic suits. It considers how soccer has evolved over the years as...

Dial in to the history of the smartphone, from its roots in Morse Code to 1997, when the first picture was transmitted over a cellphone. Plus, see how the next generation of smartphones will allow us to communicate through them just by thinking.

This video helps viewers understand how the graphic designer, or graphic artist, combines art and technology to communicate ideas through images and the layout of websites. Review responsibilities and duties, how the role influences site activity, and the skills and attributes that best fit this career.

When French engineer Ferdinand de Lesseps returned triumphantly to Paris after completing the Suez Canal in 1869, he was hailed as a national hero. Thousands raced to invest in his next, even bolder scheme: to build a great canal across Panama. His dream would cut a swathe across the South American continent and unite the vast oceans of the Atlantic and Pacific. Fortunes seemed assured as shipping would no longer have to face the terrors of Cape Horn...
