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.
One of the ancient world's most iconic buildings, the Colosseum is a monument to Roman imperial power and cruelty. Its graceful lines and harmonious proportions concealed a highly efficient design and advanced construction methods that made hundreds of arches out of 100,000 tons of stone. In its elliptical arena, tens of thousands of gladiators, slaves, prisoners, and wild animals met their deaths. Ancient texts report lions and elephants emerging from beneath the floor, as if by magic, to ravage gladiators and people condemned to death. Then, just as quickly, the Colosseum could be flooded with so much water that ships could engage in sea battles to the delight of the crowd.
For centuries, cities have been built near a fresh water supply. Without water, we'd be lucky to live three days. This most basic human need can be deadly too... the wrong supply can poison us, or get too close or careless and it can drown thousands in an instant. With every passing year, the challenge of providing water to billions of people becomes harder and harder.
Our lives are going digital. We shop, bank, and even date online. Computers hold our treasured photographs, private emails, and all of our personal information. This data is precious—and cybercriminals want it. Now, NOVA goes behind the scenes of the fast-paced world of cryptography to meet the scientists battling to keep our data safe. They are experts in extreme physics, math, and a new field called "ultra-paranoid computing," all working to forge unbreakable codes and build ultra-fast computers. From the sleuths who decoded the world's most advanced cyber weapon to scientists who believe they can store a password in your unconscious brain, NOVA investigates how a new global geek squad is harnessing cutting-edge science—all to stay one step ahead of the hackers.
Jeff Goldblum grabs his magnifying glass for a close-up at our love of tiny things. From discovering how Lago’s help kids to be adults and adults to be kids to cooking a gourmet meal for a panel of discerning judges and diving for some marvellous microorganisms, Jeff reveals there's more to small stuff than toys and cuteness. These miniatures actually shape the world around us.
Automation in the Information Age is different.
