Philosopher-comedian Emily Levine talks (hilariously) about science, math, society and the way everything connects. She's a brilliant trickster, poking holes in our fixed ideas and bringing hidden truths to light. Settle in and let her...

Whether you get it from standing on the top of Mount Everest or watching a video about the size of the universe on SciShow Space, awe can be a powerful, transformative emotion.

Ghost stories reveal much more than the ghouls and spirits that haunt them. Settle in for a spooky delight as theater educator Coya Paz Brownrigg lays out three types of bone-chilling tales and exhumes the grave truths they hold about...

Models of the universe’s early days have only been possible with dark matter as a variable, but we still don’t have proof that dark matter exists. But recently, scientists may have found a way to replicate the results without the...

You've heard of Engineers, I'm sure. But, what are Engineers? Well, it turns out that they're all kinds of people doing all kinds of neat work! Want to be one? Well, join Sabrina in this episode of Crash Course Kids where she talks about...

Scared of superintelligent AI? You should be, says neuroscientist and philosopher Sam Harris -- and not just in some theoretical way. We're going to build superhuman machines, says Harris, but we haven't yet grappled with the problems...

For most of us, the term "puke your guts out" isn't meant to taken literally. But for these animals, it's kind of useful.

We know the universe will continue to expand forever, so now we can begin to complete the first Friedmann equation, and determine the shape and geometry of our universe. At first glance, it would seem that the equation doesn't quite add...

In this video Paul Andersen explains how the location of matter can be determined at the nanoscale using the wave function. The absolute value of the wave function can be used to determine the probability of finding matter in a...

Today on Crash Course Astronomy, Phil dives into some very dark matters. The stuff we can actually observe in the universe isn’t all there is. Galaxies and other large structures in the universe are created and shifted by a force we...

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it's also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, incredible discoveries have been made....

How many of today's headlines will matter in 100 years? 1000? Kirk Citron's "Long News" project collects stories that not only matter today, but will resonate for decades -- even centuries -- to come. At TED2010, he highlights recent...

Halla Tómasdóttir managed to take her company Audur Capital through the eye of the financial storm in Iceland by applying 5 traditionally "feminine" values to financial services. At TEDWomen, she talks about these values and the...

It sounds counterintuitive, but by 2030, many of the world's largest economies will have more jobs than adult citizens to do those jobs. In this data-filled -- and quite charming -- talk, human resources expert Rainer Strack suggests...

SciShow Space takes you to a distant, ancient black hole that … really shouldn’t be, and psyches you up for the Dawn spacecraft’s final approach to Ceres!

We might be able to use slime molds to help predict the shape of matter in the universe, and the Rosetta mission may have figured out why many comets seem to be missing a bunch of nitrogen.

Today we continue our exploration of the Water Cycle by drinking some dinosaur pee. Yep! Well, it's a little less gross that it sounds. It turns out that all of the water on Earth is just constantly recycled in what we call a closed...

We learned how motion gives matter its mass, but how does motion affect time? Let's dive deeper into the true nature of matter and mass by exploring Einstein's photon clock thought experiment, and the phenomenon that is time dilation.

Anger is a powerful emotion -- it warns us of threat, insult, indignity and harm. But across the world, girls and women are taught that their anger is better left unvoiced, says author Soraya Chemaly. Why is that, and what might we lose...

Now that we know planets are common in our galaxy, how would we tell if one holds life? Sure, it will take incredibly powerful telescopes and ambitious new space missions, but what are we looking for? What are we listening for? How do we...

Every doctor makes mistakes. But, says physician Brian Goldman, medicine's culture of denial (and shame) keeps doctors from ever talking about those mistakes, or using them to learn and improve. Telling stories from his own long...

Almost all matter in the universe should have been annihilated shortly after the Big Bang, but looking around, we see galaxies, stars, planets, and, you know... us. So obviously that didn't happen, and the why of it may have something to...

In this video Paul Andersen explains how linear motion of an object can be measured using the center of mass. Internal forces within the object can be ignored since they exist in action reaction pairs. A simple way to determine the...

Basic research can seem wasteful, but it's actually a great economic investment.
