  • Federal Theatre and Group Theatre: Crash Course Theater #42

    The 1930s in the United States were pretty bad for employment in all industries, and the theater was no exception. As part of Roosevelt's New Deal, the Works Progress Administration created a division called the Federal Theatre Project. The agency created theater companies across the country to put actors and crew back to work in the theater industry. The shows were free, and thanks to forward thinking administrators, a lot of them were pretty interesting. You'll also learn about the Group Theatre today. They're the super-influential troupe, with the totally lame name. Crash Course is on Patreon!

  • When Predictions Fail: Crash Course Statistics #43

    Today we’re going to talk about why many predictions fail - specifically we’ll take a look at the 2008 financial crisis, the 2016 U.S. presidential election, and earthquake prediction in general. From inaccurate or just too little data to biased models and polling errors, knowing when and why we make inaccurate predictions can help us make better ones in the future. And even knowing what we can’t predict can help us make better decisions too. Crash Course is on Patreon!

  • Holiday Spec Holographic Lenses Experiment

    Holiday Specs holographic lenses transform any bright point of light into different magical images. When you put on these Holiday Spec glasses on your going to be surprised what you see. These are patented Holographic glasses that bend light and create holiday images from every bright light. Each set of glasses has a different holiday image from snowman, raindeer, candy cane, Gingerbread man and Santa’s face. The lenses used in Holiday Specs bend the light emanating from any light source to transform regular light into art. When you look up close to through the diffraction glasses, you are looking through a piece of material called diffraction grating. This grating is a piece of plastic that has small openings which is usually very narrow and closely spaced to each other. When light passes through these openings, it bends by an amount dependent on the type of light. For example, red light bends more than yellow light. When white light enters a diffraction grating, it separates into its fundamental colors. These colors are the same as the spectrum of colors you see in a rainbow. They’re special glasses that, when you wear them, turn a typical Christmas lights into a magical images, creating beautiful shapes in the form of a image out of each light. Light Diffraction lenses for anyone who was wondering how they work. Basically micro etchings in the plastic lenses cause light to diffract in the shape that is etch on those lenses. Understanding how this works isn't easy. It's an interesting property of nature that light going through those glasses diffracts into a Fourier transformed image. The fun thing about this is that it doesn't matter where the light moves through the glasses. The glasses will have many Fourier transformed reindeer on it all across the glass allowing the light to diffract. The result is as seen. Here's a way to see the basic hologram effect. You know those clear CDROMS that they usually put on top of a new stack of CD-R or DVRs? Sometimes those aren't just clear plastic. They actually have the CD tracks, and they give rainbow colors. Hold one of those up to your eye and go look at a distant streetlight at night. You'll see two rainbow blotches hovering near the streetlight, one on each side. The CD is a diffraction grating, and those blotches are your basic hologram. They are holograms of one pixel! (And if you stacked hundreds of CDs on your eye, you could construct a snowflake image. That's essentially how a computer makes those. Each fine pattern of parallel lines on the plastic will create a pair of glowing pixels that float in space.)

  • Peppermint Candy Water Experiment

    Peppermint Candy Water Experiment Procedure is to fill a dish with water just enough to cover the mints. You can experiment with different water temperatures. I found warm water works best. When Starlight mint are placed in the water, the candy actually dissolves in stripes! The red stripes stay separated for a time due to the variance in the sugar content in the surrounding water. Sugar dissolves in water because water breaks the bonds between sugar molecules. Heat makes the sugar molecules move faster, speeding up this process and is why I use warm water. : ) Liquids, such as saliva, react with mints, and depending on their composition, dissolve them quickly or slowly. As mints dissolve, they release their flavorful oils and energizing sugars. NOTE: Starlight Mints are NOT safe for kids with nut allergies – they are produced in a factory where they can come into contact with nuts!

  • The Harlem Renaissance: Crash Course Theater #41

    In the 1920s, there was a blossoming of all kinds of art made by African Americans in the New York neighborhood Harlem. Let's call it a renaissance. While all the arts were having a great run, some extremely interesting things were happening in the theater. Writers like Langston Hughes and Zora Neale Hurston were writing plays, and black theater companies were drawing larger audiences than ever before. Crash Course is on Patreon!

If they do annihilate, then the interference pattern changes and there is a probability for both particles to be detected in the "dark arms" of the detector, that is, where previously there was no probability for detection for either particle. The paradox has implications for local realism, contextuality, lorentz elements of reality, and has been used as an experimental setup for weak measurements.

  • Can animals be deceptive? - Eldridge Adams

    Sign up for our newsletter and never miss an animation: http://bit.ly/TEDEdNewsletter View full lesson: https://ed.ted.com/lessons/can-animals-be-deceptive-eldridge-adams A male firefly emits a series of enticing flashes. He hopes a female will respond and mate with him. A female from a different species mimics his patterns: by tricking the male, she lures him in -- and turns him into a meal. Where else do we see this kind of trickery in the animal kingdom? Eldridge Adams details the surprising complexity of how animals manipulate predators, prey and their rivals.

  • The HOT Chocolate Effect

    This experiment is called the Hot Chocolate Effect. You can do it yourself quite easily. Pour Cocoa mix in the cup and pour HOT water into the cup and then tap the rim of your mug several times with your spoon and listen to the pitch. Did it change while you were tapping? Probably Not! Now this is where SCIENCE becomes FUN! Give it a couple of stirs and start tapping again. What do you hear? You should notice that the pitch frequency of your tapping gets higher and higher. Give it another stir and tap again. The pitch will go down and then rise again! What’s the science behind it? DRUM ROLL.....answer is BUBBLES. Adding powdered hot cocoa mix doesn’t just add a sweet chocolate flavor to your water, it adds tiny bubbles of air as well. As you stir in the chocolate you also mix the air bubbles into the liquid. All of those bubbles slow down the speed of sound in the hot chocolate. This lowers the frequency or the pitch of the sound waves that travel through the mug when tapped. As the water spins around in the mug, the bubbles rise to the top and pop. With fewer bubbles in the hot chocolate, the speed of sound increases and the frequency does too so you hear a higher pitch. Now stir it again and it dissolves more bubbles and it starts all over again! The hot chocolate effect, also known as the allassonic effect, is a phenomenon of wave mechanics first documented in 1982 by Frank Crawford, where the pitch heard from tapping a cup of hot liquid rises after the addition of a soluble powder(Coca mix, instant coffee). Hope you enjoyed this experiment. Please Like and SHARE. And thanks for watching

  • Little Theater and American Avant Garde: Crash Course Theater #40

    In the early 20th century United States, big melodramatic productions were on Broadway, and everywhere across the country. Which inevitably led to an Avant-Garde backlash. An interesting part of the backlash was Little Theater, a movement that embraced smaller, more emotional, and less profitable forms of drama. One of Little Theater's most notable practitioners, Eugene O'Neill changed the theatrical landscape with groundbreaking plays like The Iceman Cometh and Long Day's Journey into Night.
