Purple Clouds got them trembling under the covers over their heads.

They'll never understand science, that's for certain.

Doesn't give me a lot of confidence in people who present themselves as journalists to note their fear at stuff they see in the sky.

The Nobel Prize in Physics 1904

Lord Rayleigh


Lord Rayleigh (John William Strutt)

Born: 12 November 1842, Langford Grove, Maldon, Essex, United Kingdom

Died: 30 June 1919, United Kingdom

Affiliation at the time of the award: Royal Institution of Great Britain, London, United Kingdom

Prize motivation: "for his investigations of the densities of the most important gases and for his discovery of argon in connection with these studies"

Field: Gas physics, molecular physics


Lord Rayleigh's first researches were mainly mathematical, concerning optics and vibrating systems, but his later work ranged over almost the whole field of physics, covering sound, wave theory, colour vision, electrodynamics, electromagnetism, light scattering

John William Strutt, 3rd Baron Rayleigh


John William Strutt, 3rd Baron Rayleigh, OM (12 November 1842 – 30 June 1919) was an English physicist who, with William Ramsay, discovered the element argon, an achievement for which he earned the Nobel Prize for Physics in 1904. He also discovered the phenomenon now called Rayleigh scattering, explaining why the sky is blue

Blue Sky

The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere. This scattering, called Rayleigh scattering, is more effective at short wavelengths (the blue end of the visible spectrum). Therefore the light scattered down to the earth at a large angle with respect to the direction of the sun's light is predominantly in the blue end of the spectrum.


Rayleigh Scattering

Rayleigh scattering refers to the scattering of light off of the molecules of the air, and can be extended to scattering from particles up to about a tenth of the wavelength of the light. It is Rayleigh scattering off the molecules of the air which gives us the blue sky. Lord Rayleigh calculated the scattered intensity

Rayleigh scattering


Rayleigh scattering, named after the British physicist Lord Rayleigh, is the elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the light. The particles may be individual atoms or molecules. It can occur when light travels through transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering is a function of the electric polarizability of the particles.

Rayleigh scattering of sunlight in the atmosphere causes diffuse sky radiation, which is the reason for the blue color of the sky
