How ancient Romans made stronger concrete than today
AdultsCitiesConstructionHistoryScienceEngineeringMany structures built by ancient Romans around 2,000 years ago are still standing, and some are still in excellent condition. Over the last decade, researchers have come discover the Romans' secret concrete recipe that has maintained so many of its now-ancient buildings.
How the Pyramids Were Built (Pyramid Science Part 2!)
AdultsConstructionHistoryEngineeringJust 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.
How the Pyramids Were Built (Pyramid Science Part 1!)
AdultsConstructionHistoryEngineeringWho built the pyramids? The colossal geometric monuments found at Giza and elsewhere in Egypt are some of Earth's most impressive constructions. Pyramids are truly wonders of the ancient and modern world.

Why don't perpetual motion machines ever work? - Netta Schramm
AdultsScienceTechnologyWorkEngineeringPerpetual motion machines - devices that can do work indefinitely without any external energy source - have captured many inventors' imaginations because they could totally transform our relationship with energy. There's just one problem: they don't work. Why not? Netta Schramm describes the pitfalls of perpetual motion machines.
