    What are those spots you observe after rubbing your eyes? - Paul CJ Taylor

    Explore the science of afterimages, which are the visual illusions that appear in the eyes after exposure to an image or bright light. -- In the 1600s, Isaac Newton conducted a series of experiments to better understand the lights and colors that sometimes appear when your eyes are closed. If you’ve ever sat around an evening campfire or unintentionally glanced at the Sun, you may have noticed illuminated patterns briefly dance along your vision. So how do these visual illusions form? Paul Taylor explores the science of afterimages. Lesson by Paul Taylor, directed by Sofia Pashaei.

    Explore the ever-evolving structure of the Milky Way galaxy, and find out how it got its spiral shape. -- Thirteen billion years ago, the gas and dust particles that eventually became our Milky Way were whizzing around in every direction.

    Why do your jeans wear out so quickly? - Madhavi Venkatesan

    Trace the life cycle of a pair of denim jeans, and discover the labor and environmental costs of this fashion staple. -- The first pairs of jeans were designed for durability; denim was constructed as a sturdy weave worn by sailors and miners.

And each new pair you buy has a much higher cost than you might think. Madhavi Venkatesan traces the life cycle of jeans. Lesson by Madhavi Venkatesan, directed by Sofia Pashaei.
