In 2021, Viviane Callier wrote for Quanta about how living things often use diffraction to alter their colors. Slow Stability Last year, the mathematician Elena Giorgi posted a 900-page proof that slowly rotating black holes are stable. Rachel Crowell writes about the proof and Giorgi’s broader research interests for Science News. In their proof, Giorgi and her colleagues considered what would happen if a rotating black hole were struck by gravitational waves. Steve Nadis explained their proof by contradiction for Quanta last August.

# History C hanel

Hans Christian Andersen, one of the world’s greatest storytellers, is born in Odense, near Copenhagen.

During Andersen’s boyhood, his father died, and the child went to work in a factory briefly. However, he showed great talent for languages and entered the University of Copenhagen in 1828. The following year, he published his literary spoof "A Journey on Foot from Holmen's Canal to the East Point of Amager," which became his first important work.

Andersen wrote several plays that flopped, but he achieved some success with his novel The Improvisatore (1835). Meanwhile, he entertained himself by writing a series of children’s stories that he published as collections. The first, Fairy Tales Told for Children, (1835) included “The Princess and the Pea.” Andersen released new collections every year or two for decades as he traveled widely in Europe, Africa, and Asia Minor. His stories include “The Ugly Duckling,” “The Little Mermaid” and “The Emperor’s New Clothes.” He died in 1875 at age 70.
