Abstract Michael Berry

Nature's optics and our understanding of light

Michael Berry, H H Wills Physics Laboratory, University of Bristol, UK

Optical phenomena visible to everyone abundantly illustrate
important ideas in science and mathematics. The phenomena
considered include rainbows, sparkling reflections on water, green
flashes, earthlight on the moon, glories, daylight, crystals, and the
squint moon. The concepts include refraction, wave interference,
numerical experiments, asymptotics, Regge poles, polarization
singularities, conical intersections, and visual illusions.
