"LittleBits ... consists of tiny circuit-boards with specific functions engineered to snap together with magnets. No soldering, no wiring, no programming, just snap together for prototyping, learning and fun. Each bit has a specific function (light, sound, sensors, buttons, thresholds, pulse, motors, etc), and modules snap to make larger circuits. ... littleBits are small, simple, intuitive, blocks that make creating with sophisticated electronics...

Dispite popular belief, Edison did not invent the light bulb - many people contributed to the invention. Mind you, the first lamp was invented around 70,000 BC. This program examines Edison's actual contribution of improving the light bulb to become a practical, affordable, and safe product. Modern-day lighting innovations are quite startling, as many of them we can't even see with the naked eye. Consider lasers. Nobody knew what to make of this idea...

Starting with Francis Hauksbee's 1705 Royal Society demonstration, in which he produced static electricity and a nascent form of neon lighting, this program looks at the origins of our understanding of electricity and how it could be harnessed. The film profiles many of the scientists and "natural philosophers" who first studied electricity, including Stephen Gray, Pieter van Musschenbroek, Luigi Galvani, and several others. Viewers learn about Benjamin...

Today we can hardly imagine life without electrical power - it defines our era. It creates human connections. It is the lifeblood of civil society. But how did we arrive here, at a place in which our understanding of electricity is matched, if not overwhelmed, by our dependence on it? Bringing the scientific history of electricity to a dramatic conclusion, this program describes how a new age dawned - how researchers discovered electric fields and...
