    How do airplanes actually remain in flight? - Raymond Adkins

    Explore the physics of flight, and discover how aerodynamic lift generates the force needed for planes to fly. -- By 1917, Albert Einstein had explained the relationship between space and time. But, that year, he designed a flawed airplane wing. His attempt was based on an incomplete theory of how flight works. Indeed, insufficient and inaccurate explanations still circulate today. So, where did Einstein go wrong? And how exactly do planes fly? Raymond Adkins explains the concept of aerodynamic lift. Lesson by Raymond Adkins, directed by Michael Kalopaidis, Zedem Media.

    Can a black hole be destroyed? - Fabio Pacucci

    Are black holes indestructible? Explore the theory of Hawking radiation, a process that could lead a black hole to gradually lose mass and evaporate. -- Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes. But is there any way to destroy a black hole? Fabio Pacucci digs into the possibility.

    Why is cotton in everything? - Michael R. Stiff

    Dig into the science of how cotton transforms from seed to fiber, and how these cotton fibers are used to make everything from fabrics, to currency, and fishing nets. -- Centuries ago, the Inca developed ingenuous suits of armor that could protect warriors from even the fiercest physical attacks. These hardy structures were made not from iron or steel, but rather something unexpectedly soft: cotton. Today cotton is used to make everything from fabric, to currency, diapers and fishing nets. Michael R. Stiff explores the science of what makes cotton so versatile. Lesson by Michael R. Stiff, directed by WOW-HOW Studio.
