Beaks are horny, projecting structures that form the mandibles of birds. They are generally strong, sharp, and useful in striking and tearing. The beak's function varies significantly from species to species; it can be used to kill prey, probe for food, manipulate objects, groom, or feed young birds, and its size and shape vary accordingly. Though beaks are worn down over time, they grow continuously throughout the birds' lifetimes. What species of bird uses its beak to "kiss" during courtship?

Chanel No. 5 is the first fragrance from Parisian couturier Gabrielle "Coco" Chanel, who set out to make the most expensive perfume in the world, a goal she accomplished with this jasmine scented formula. Its name supposedly derives from the fact that multiple perfume samples, labeled No. 1, No. 2, etc., were mixed for Coco's approval, and it was bottle No. 5 that met with her liking. The perfume's original formulation involves the use of a glandular secretion harvested from what furry mammal?

Kierkegaard was a Danish philosopher and theologian who is often recognized as the first existentialist philosopher. The dominant theme of his writings is that "truth is subjectivity." In his aesthetic works, he develops an "existential dialectic" in opposition to the Hegelian dialectic, and in his religious writings, he deals with issues such as the nature of faith and the institution of the Christian church. Why did Kierkegaard publish many of his earlier works under pseudonyms?
