    The Seven Years War and the Great Awakening: Crash Course US History #5

    Hi, I’m John Green. This is Crash Course U.S. History. And today we’re going to discuss the events that led to the events that led to the American revolution. So, we’ll begin with the Seven Years War which, as Crash Course World History fans will remember, Winston Churchill referred to as as the “First World War”. The Americans called it “The French and Indian War”, the Prussians called it “The Third Silesian War”, Swedes called it the Pomeranian War. For today, we’re just going to call it the Seven Years War on account of how it lasted for 9 years. [Theme Music] So, here at Crash Course, we take a…

    How to Tell Customers You Exist: Crash Course Entrepreneurship #11

    Here’s a cold, hard truth: no business, no matter how innovative and amazing it is, will survive if people haven’t heard of it. If people don’t know something exists, they’ll never be able to purchase it. Beyonce might drop a surprise album, but then she promotes the heck out of it. The hype she gets from the surprise is part of her entrepreneurial strategy! Ever since we’ve had products and services, we’ve needed channels to create awareness and communicate with our customers. And as our culture has evolved, so have our channels — from simple posters in the 1800s, to the launch of Pinterest (and the heyday of DIY wedding…

    The Integumentary System, Part 2 – Skin Deeper: Crash Course A&P #7

    Look at all this stuff! Soaps, lotions, conditioners, polishes — all from that huge section of your local store that’s dedicated solely to the grooming of your skin, hair, and nails. Some might see these things as the trappings of vanity. But me? I see them as the tools for the care, maintenance, and — sure, sometimes decoration — of the integumentary system. Now, true, in spite of what the cosmetics industry may lead you to believe, your integumentary system is more than just a place to put eye shadow and hair product in the hopes of attracting a mate. This collection of resilient tissues, ranging from the sharp and…

    AI Playing Games: Crash Course AI #12

    Jabril: D7 John-Green-bot: Miss. John-Green-bot: I-9 Jabril: NOOOOOOOOOO Hey, I’m Jabril and welcome to Crash Course AI! John-Green-bot might struggle with some things like natural language processing and moving through the real world, but using AI he’s pretty good at board games. AI researchers spend a LOT of time trying to teach AI how to beat humans at games, & this isn’t just because games are fun. Games provide constrained scenarios for testing new AI algorithms and approaches. In a game, it’s easy to know whether the AI is winning or losing, because there’s usually a score or some objective measure of “winning.” This is great because AI learns from…

    Party Systems: Crash Course Government and Politics #41

    Hello, I’m Craig and this is Crash Course Government and Politics. And today we’re gonna talk about, well, mostly history. Wait Stan, this isn’t Crash Course History. This must be some kind of exception, like the Mongols. [Mongoltage] Apparently we’re not stepping on anybody’s toes by talking about the history of American political parties, as long as we stay away from history in general. Thank goodness, we wouldn’t want to start a Crash Course interdisciplinary feud. Just kidding, I’m totally feuding with that Phil guy over at Astronomy. [Theme Music] Political historians like to divide America into eras according to which parties were active at the time. These are called…

    How to Sell Anything: Crash Course Entrepreneurship #12

    Once upon a time, there was a woman with a strong entrepreneurial spirit who was ready to transform her side hustle into a magnificent full-time business. She identified a problem and crafted a solution, and now she needs to make her voice heard by the people. But how? This story might sound familiar. Any entrepreneur’s path is full of critical sales, elevator pitches, and persuasion. We want people to buy our product or service, but we also want them to believe in our ideas and seek our expertise. It can be hard to strike the right tone or know what’s going to appeal to someone, but there are tricks. We…

    The Industrial Revolution: Crash Course European History #24

    Hi I’m John Green and this is Crash Course European History. So we’re going to turn our attention now to the Industrial Revolution, one of the most significant developments in human history. Like, imagine with me that it’s 1820. I got this idea from the economist Robert Gordon by the way. You live in, say, England. You probably work in agriculture. When you walk to town, you’re either pulling your own cart, or if you’re lucky you have a horse. You have no running water or electricity. When you wash your few items of clothing, you do so by hand. You cook over a fire. You think of time not…

    English Civil War: Crash Course European History #14

    Hi I’m John Green and this is Crash Course European History. And as we saw last week, Absolutism was in the air during the seventeenth century, but not just in France. Across the English Channel, King James VI of Scotland became King James I of England after the death of the childless Elizabeth in 1603, and he found himself thinking, “You know, I might not agree with everything those French Catholics believe, but they are onto something when it comes to the Divine Right of kings to have absolute power.” The inhabitants of the British Isles, however, weren’t so sure. In fact, Protestant reformers were imagining a different idea of…
