They carry meaning, emotion, and power. But underneath it all, language is really just physics. In this episode, we explore how physics is at the core of every syllable, starting with the first word most of us ever speak.

Just because something is difficult doesn’t mean it’s impossible. Over the past centuries, archaeologists, historians, and engineers have reconstructed a great deal of the technology and science used to build the Egyptian pyramids. This week we look at ancient Egyptian mathematics, building techniques, tools, and culture to reconstruct the Great Pyramid’s construction. REFERENCES: Fall, Abdoulaye, et al.
