Where science fiction becomes science fact - that is the place Hank is exploring in today's episode of SciShow. Many inventions we use today were first imagined in stories that described fantastical futures. Hank talks about the origins of four of these: the cell phone, the submarine, the telemanipulator (or robot arm), and the taser.
SILICON VALLEY tells the story of the pioneering scientists who transformed rural Santa Clara County into the hub of technological ingenuity we now know as Silicon Valley. The film spotlights the creativity of the young men who founded Fairchild Semiconductor and in particular the brilliant, charismatic young physicist Robert Noyce. Their radical innovations would include the integrated circuit that helped make the United States a leader in both space exploration and the personal computer revolution, transforming the way the world works, plays and communicates, making possible everything from the Apollo program to smart phones, from pacemakers to microwaves.
In the first episode, Andrew looks at how people live in five of the world's biggest megacities: London, one of the world's oldest megacities; Dhaka, the world's fastest-growing megacity; Tokyo, the largest megacity on Earth; Mexico City, one of the most dangerous cities in the world; and Shanghai, arguably the financial capital of the world. Andrew compares the sleek skyscrapers and rapid modernisation of Shanghai to the colourful street culture and geographic sprawl of Mexico City. He spends a night living in a one-room shack in Dhaka's toughest slum, taking his turn to fetch water, cook and clean; and he rents a friend in the efficient and high-tech, but alienating, city of Tokyo. As he gets under the skin of each unique metropolis, Andrew discovers how the structure of each megacity defines every aspect of its inhabitants' daily lives. And he considers what the megacities of the future can learn from the metropolises of today.
