[edit] Spoilers

Somebody said it's "ridiculous" to put a spoiler warning in a physics article. However, the warning was in the "Cultural Impact" section because said section gives away the ending of the musical CATS. With this is mind, should there be a spoiler warning, or is this just a case of somebody making judgments without even reading the article? If there's a good reason why that should not be marked as a spoiler, I won't question the issue further, but I would like to know this person's reasoning... Lycanthrope777 19:21, 28 May 2007 (UTC)

How can people in 1902 predict the existence of something the existence of which was proven experimentally in 1899?

[edit] First and Second Heaviside Layers?

The book “Wonders of Science” (Metro Publications, New York, 1943) describes a first Heaviside layer (40-50 miles altitude) and a second Heaviside layer (100-120 miles altitude). Both layers are descibed to contain “minute nitrogen crystals” that reflect wireless waves to the Earth. Does anyone know the history on how this evolved into our present understanding? —Preceding unsigned comment added by ShermansPlanet (talk • contribs) 17:28, 18 December 2007 (UTC)
