Simone Biles: Defying the laws of physics?
https://plus.maths.org/content/simone-biles
EXCERPT: Simone Biles is a gymnast in a league of her own. In the 2016 Olympics in Rio she stunned audiences with a move some thought defies the laws of physics: the Biles, which incorporates a double somersault, a twist in mid-air, and a blind landing (see the video below). How does she do it? We asked sports scientist Ciarán McInerney and sports engineer John Kelley to explain the physics of the Biles....
Spontaneous spirals

EXCERPT: Spirals are common in nature. We've all admired the beautiful spirals that occur in the sea shells, we can find spirals in plants, and even in the arms of galaxies or weather patterns. There are also situations in which spirals aren't a result of slow growth, but occur spontaneously in biological or chemical systems. A famous example from chemistry is the Belousov-Zhabotinsky (BZ) reaction: when several chemicals are mixed together in a petri dish, the resulting solution forms changing spiral patterns, as seen in this video....
