Today we're so excited to announce the free Crash Course App! (Available now for Apple and Android phones and tablets.) The app is a portal to find all of our thousands of videos and a platform to help you review what you've learned in those videos. At the heart of the app are decks which are essentially really beautiful flashcards that transform into multiple choice questions in quiz mode. The app currently supports decks for all episodes of Anatomy & Physiology, Chemistry, and Organic Chemistry, and we'll be continually adding more content. So please download the app and let us know what you think!

Music plays a big part in many of our lives. Whether you just like to listen or you enjoy playing an instrument, music is powerful. So what is music? How does it work? What are the physics of music? In this episode of Crash Course Physics, Shini talks to us about how music functions in terms of waves and how these waves interact with our ears.
