In which John Green teaches you WHY World War I started. Or tries to anyway. With this kind of thing, it s kind of hard to assign blame to any one of the nations involved. Did the fault lie with Austria-Hungary? Germany? Russia? Julius Caesar? One thing we can say for sure is that you can t blame the United States of America for this one. Woohoo! Well, you can hardly blame the US. Crash Course is on Patreon! You can support us directly by signing up at http://www.patreon.com/crashcourse Want to find Crash Course elsewhere on the internet?

In which John Green, Hank Green, and Emily Graslie teach you about, well, everything. Big History is the history of everything. We re going to start with the Big Bang, take you right through all of history (recorded and otherwise), and even talk a little bit about the future. It is going to be awesome. In the awe-inspiring sense of the word awesome. In this episode, we walk you through the start of everything: The Big Bang. We ll look at how the universe unfolded at its very beginning, and how everything in the universe that we know today came into being. So that s kind of a big deal, right?

View full lesson: http://ed.ted.com/lessons/what-is-the-heisenberg-uncertainty-principle-chad-orzel The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time. Chad Orzel navigates this complex concept of quantum physics. Lesson by Chad Orzel, animation by Henrik Malmgren.

In this video we show you step-by-step how to install a tongue and groove floor directly onto a Tiny House trailer. We re incredibly lucky to have master builder Alan Drayton and his team from Bio Build Ltd (http://www.biobuild.co.nz) helping us on our build and giving us their expert advice. The wood that has been selected for the floor is New Zealand Lawson Cypress from St Lukes Timber (http://www.stlukestimber.co.nz). It s been chosen for its great performance and strength to weight ratio. The screws for this project were supplied by Fortress Fasteners (http://www.fortressfasteners.co.nz). This video shows the floor being attached to a custom built Tiny House steel trailer, but the same principles apply if you are installing on wooden joists.

View full lesson: http://ed.ted.com/lessons/particles-and-waves-the-central-mystery-of-quantum-mechanics-chad-orzel One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion? Chad Orzel recounts the string of scientists who built on each other’s discoveries to arrive at this ‘central mystery’ of quantum mechanics. Lesson by Chad Orzel, animation by Joana Bartolomeu.

In which John Green teaches you about World War I and how it got started. Crash Course doesn t usually talk much about dates, but the way that things unfolded in July and August of 1914 is kind of important to understanding the Great War. You ll learn about Franz Ferdinand, Gavrilo Princip, the Black Hand, and why the Serbian nationalists wanted to kill the poor Archduke. You ll also learn who mobilized first and who exactly started the war. Sort of. Actually, there s no good answer to who started the war, but we give it a shot anyway. Crash Course is on Patreon!

Here, Labovic explains how she and her team of animators created a pop-up book to visualize Pangaea -- and how you can make your own. Lesson and animation by TED-Ed.
