How ancient Romans made stronger concrete than today
Adults EngineeringMany 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 1!)
Adults EngineeringWho 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.
How the Pyramids Were Built (Pyramid Science Part 2!)
Adults EngineeringJust 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.
Jumping Water Droplets Could Be the Future of Cooling Computers
Adults EngineeringEngineers have created a new water-based cooling system that could put an end to electronics crashing and overheating.
Why don't perpetual motion machines ever work? - Netta Schramm
Adults EngineeringPerpetual 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.

Atlas, The Next Generation
Adults EngineeringA new version of Atlas, designed to operate outdoors and inside buildings. It is specialized for mobile manipulation. It is electrically powered and hydraulically actuated. It uses sensors in its body and legs to balance and LIDAR and stereo sensors in its head to avoid obstacles, assess the terrain, help with navigation and manipulate objects. This version of Atlas is about 5' 9" tall (about a head shorter than the DRC Atlas) and weighs 180 lbs.
Why are plane windows round?
Adults EngineeringWe often learn the most from our failures, this is particularly true for advancements in the field of engineering. Unfortunately for the engineers in the aviation industry, the prices to pay for failure are high. This will be a reoccurring theme in my videos, trust me. The flip-side of this unforgiving industry, is that it consistently provides learning opportunities for engineers, because failure is not an option when peoples lives are at risk.

Boeing: Lightest. Metal. Ever.
Adults EngineeringMicrolattice is the lightest metallic structure ever made. At 99.99% air, it's light enough to balance on top of a dandelion, while its structure makes it strong. Strength and record breaking lightness make it a potential metal for future planes and vehicles.
How Does A Sailboat Actually Work?
Adults EngineeringHow does a sailboat work? The standard idea is that the wind pushes the sails from behind, causing the boat to move forward. Although this technique is used at times, it is not the most efficient way to sail a boat (and it means the boat can never go faster than the wind). Lift is the key mechanism driving a boat forwards. As air flows over the sails, it moves faster over the outer side, creating lower pressure than on the inner side. This produces a force which is mostly to the side and a bit forwards.
How batteries work
Adults EngineeringBatteries are a triumph of science-they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they finally die. Why does this happen, and how do our batteries even store so much charge in the first place? Adam Jacobson gives the basics on batteries.
