The optics of rainbows and fogbows is investigated theoretically for single water drops using Mie theory. Included in the calculations are a realistic solar illumination spectrum and the finite size of the Sun. Drop radii range from 3 to 300 µm. Results are presented on the location, width, contrast and color of both primary and secondary rainbows ...

Inspired by a Native American myth, "Rainbow Crow" explores themes of self-discovery and sacrifice. In a forest that is perpetually spring-like, the animals are happy and carefree. But when winter descends for the first time ever, their lives are suddenly in grave danger and only Rainbow Crow can save them.

Navigating the ontology of color used to be a simple affair. There was the naive view that colors really are in objects the way they appear, and the view that they are secondary qualities to cause certain experiences in us. Today, there are myriad well-developed views but no satisfactory taxonomy of philosophical theories on color.

Rainbow is a fast asymmetric multivariate signature algorithm proposed by J. Ding and D. Schmidt in [5]. This paper presents a cryptanalysis of Rainbow which enables an attacker provided with the public key to recover an equivalent representation of the secret key, thus allowing her to efficiently forge a signature of any message.

The Airy theory of the rainbow is extended to polarized light. For both polarization directions a simple analytic expression is obtained for the intensity distribution as a function of the scattering angle in terms of the Airy function and its derivative. This approach is valid at least down to droplet diameters of 0.3 mm in visible light.

“You fooled me. I never dreamt,” George said to the pasty gray face in the mirror. As a child, he had worked out complicated schemes of how the world must be constructed. This led to that, and that led to this. When this and that no longer fit together, he began to squint, and limit his view to the essential. At any moment, the sky might break open and

A theory for the brightness of rainbows is presented. The light reaching the observer consists of a beam of singly scattered sunlight, originating from the directly illuminated portion of a rainswath, which, in turn, has suffered depletion by scattering or absorption in its path through the atmosphere.
