Spinning toys and tops have unusual behaviors. The famous tippe top flips itself over and spins on its stem. The PhiTOP stands up on its end, which you can also do with a hard-boiled egg. These behaviors all have to do with torque and angular momentum, like a bicycle wheel precessing around a rope due

Rogue waves – enormous, spontaneous surface waves in the open ocean – were once the tall tales of sailors. They are waves that reach 2-3x taller than the largest average waves in the area, reaching heights of 75 – 100ft. With the help of a ESA satellite survey, the scientific community now accepts they happen

Holograms are photographic recordings of 3D scenes. Unlike a camera, which captures one view through a small viewer focused by a lens, holograms capture an entire light field which allows them to recreate the 3D scene. Shimmery 2D projections, like pre-recorded Pepper’s ghost illusion, are often confused with 3D holograms. Pepper’s Ghost Tutorials instagram.com/thephysicsgirl facebook.com/thephysicsgirl

How did the field of quantum mechanics come about in the first place? The Rayleigh-Jeans catastrophe, also known as the ultraviolet catastrophe was a prediction by the Rayleigh-Jeans law that a blackbody would radiate infinite amounts of ultraviolet light.
