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.
The World Trade Center and Sears Tower were record-setting skyscrapers made possible by cutting-edge engineering innovations, but just as these American icons set new standards in construction, dark and insidious forces were poised to undo it all.
By the year 2050, three quarters of the world’s population will live in urban areas. Looking at robotic systems being developed worldwide we can take a glimpse at the city life of the future. Private transportation with self-driving cars, our homes with automated systems - robots are in our future.
The Hubble Telescope, launched in 1990, has captured unparalleled views of the universe, transforming modern astronomy and transfixing the world with its spectacular images. But building this orbiting observatory would prove to be a rollercoaster ride for all involved, requiring engineers, scientists, and astronauts to venture into uncharted territory. From construction to release, from ridicule to redemption, this is the story of the unsung heroes who turned man's quest to uncover the mysteries of the universe into reality.
The world's electric grids are aging and vulnerable. Now, engineers are making a dangerous trek to prove there is a better way to bring power to the people. Engineers make a dangerous trek across the Himalayas to bring power to a remote monastery.
