reported Opik's finding while covering a planetary colloquium held in Liege, Belgium, in July 1962.
Bearing the name of Marcel Minnaert
, a renowned Dutch astrophysicist, the Minnaert building houses facilities for Utrecht University's geophysics department.
In Light and Color in the Outdoors (Springer-Verlag, 1993), Belgian astronomer Marcel Minnaert
tells how you can count the supernumerary bows and look at their spacing to gauge the size of the raindrops producing them.
In his classic book Light and Color in the Outdoors (Springer-Verlag, 1993), Belgian astronomer Marcel Minnaert
noted, "Generally speaking, we are inclined to call the predominating color in our surroundings white or nearly white." This applies to a brilliant planet or star viewed at night with the enormous light grasp of a telescope.
But then, during that summer of 1976, I read Light and Colour in the Open Air by Dutch astronomer Marcel Minnaert
Years ago, Netherlands astronomer Marcel Minnaert
did an experiment.
, a pioneering authority on optics in nature, has described these phenomena in a section called "Differences between an Object and its Reflected Image" in his classic book The Nature of Light & Colour in the Open Air.
For instance, in his book Light and Color in the Outdoors (Springer-Verlag, 1993), Marcel Minnaert
describes the Brush as a slender and continuous yellow ellipse, like a cucumber slightly pinched in the middle, with a small blue cloud on either side of the pinch.
also discusses the phenomenon in his classic book, Light and Color in the Outdoors (Springer-Verlag, 1993), as does John Naylor in Out of the Blue: A 24-Hour Skywatcher's Guide (Cambridge University Press, 2002).
Closer examination reveals that about 80 percent deals with atmospheric phenomena or, better yet, the behavior of "light and color in the open air." A book by that title (later reprinted in 1983 as Light and Color in the Outdoors) by the late Dutch astronomer Marcel Minnaert
inspired Naylor to look at the daytime sky, to "look afresh at things I had all but ignored."
Belgian-born Dutch astronomer Marcel Minnaert
wrote about this phenomenon in his book Light and Colour in the Open Air (published later as Light and Color in the Outdoors).
In The Nature of Light and Color in the Outdoors, Marcel Minnaert
mentions coronas in a clear sky but does not discuss their shape.
