The brutal medieval king who inspired "Macbeth" - Benjamin Hudson
Dig into the history that inspired Shakespeare’s tragedy, “Macbeth,” and find out just how much of the play is based on real events. -- Of all Shakespeare’s plays, perhaps none is stranger than “Macbeth”— a parable on power rife with supernatural elements. But according to texts from the 11th century, this tragedy has its roots in reality. What’s more, other accounts mention witches, prophecies, and arboreal armies. Which raises the question: just how much of Shakespeare’s strange story is true? Benjamin Hudson investigates. Lesson by Benjamin Hudson, directed by Sarah Saidan.

Why do we get two tides each day? - Elise Cutts
Dig into how the Sun and Moon are responsible for the tides on Earth, and what this force looks like on other celestial bodies. -- In the 17th century, Isaac Newton offered the first gravitational explanation of tides. As he correctly identified, tides are choreographed by the motions of celestial objects, and Earth’s tides in particular are mostly driven by the Moon. But the precise nature of this relationship is actually quite nuanced. Elise Cutts explains how the Sun and Moon are responsible for the tides.

Dig into the challenges of modern pastoralism, a form of agriculture where farmers guide livestock to seasonal grazing areas. -- For millennia, livestock farmers strategically guided animals to seasonal grazing areas.
