Kinetic and potential energy are defined as combinations of more basic quantities: position, velocity and mass. These combinations are chosen so that their sum is conserved. It’s actually remarkable that there’s any such combination of...

There are a lot of things that are still not fully understood about the species Homo sapiens - what makes us US? What makes us move the way we do, think the way we do, and kill the way we do? Today on SciShow News, Hank gives us a little...

In this video Michael Aranda explains what the Leidenfrost Effect is, and how it can cause liquid to 'levitate'.

You might think that fish ride the undercurrents with all their buds to avoid the hungry mouths of predators - safety in numbers, right? But, it turns out, there’s more to consider when asking why fish swim in schools.

There are a lot of things that are still not fully understood about the species Homo sapiens - what makes us US? What makes us move the way we do, think the way we do, and kill the way we do? Today on SciShow News, Hank gives us a little...

In a friendly, high-speed presentation, Will Wright demos his newest game, Spore, which promises to dazzle users even more than his previous masterpieces.

In this far-seeing talk, Seth Priebatsch shows how game dynamics are reshaping the world -- from a classroom where students "level up" instead of being graded ,to a pervasive game called "happy hour" that you may already be playing. Get...

MIT researcher Deb Roy wanted to understand how his infant son learned language -- so he wired up his house with videocameras to catch every moment (with exceptions) of his son's life, then parsed 90,000 hours of home video to watch...

People-powered resistance: can it work? Srdja Popovic led the nonviolent movement that took down Milosevic in Serbia in 2000; he lays out the plans, skills and tools that a people-powered movement needs -- from nonviolent tactics to a...

Lighting architect Rogier van der Heide offers a beautiful new way to look at the world -- by paying attention to light (and to darkness). Examples from classic buildings illustrate a deeply thought-out vision of the play of light around...

Can Twitter be saved? In a wide-ranging conversation with TED's Chris Anderson and Whitney Pennington Rodgers, Twitter CEO Jack Dorsey discusses the future of the platform -- acknowledging problems with harassment and moderation and...

In this episode of Crash Course Physics, Shini is very excited to start talking about Fluids. You see, she's a Fluid Dynamicist and Mechanical Engineer, so fluids are really important to her. Actually they're really important to anyone...

SciShow Psych host Brit Garner joins Hank to talk about wildlife conservation, big data, and Complexly’s new show Nature League, and Jessi stops in with a whole mess of invertebrates.

Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a...
