| In the service of clouds: my latest library haul to answer a basic question. |
 |
| This is Richard Feynman's friendly question in his lecture, "Radiation Damping. Light Scattering." |
 |
| This was his unfriendly answer. I get it, but not really. So I found a different book. |
 |
| This is from Why the Sky is Blue by Gotz Hoeppe. |
 |
| As is this...which made some sense, but is certainly uncloudlike. |
 |
| This neat chart shows the relative sizes of particles in the atmosphere compared to wavelengths of visible light. |
 |
| Look how much bigger they are than... the lines at the top! Huh? |
 |
| I kept reading and was greatly encouraged by the "made simple" pitch. |
 |
| Oh, but it wasn't simple at all. In the penultimate paragraph of this long chapter , the author stated: "The reason is simply that these particles are too big to big to be electrically polarized as a unit by an incoming light wave, and this prevents them from becoming oscillating dipoles." |
 |
| This sure is simple. |
 |
| I think the answer might be in here. |
 |
| But I am going to need a shrinky drink. (Image source: wwww.victorianweb.org) |
