A large portion of this article appears to have been copied from thought experiments lain, which was last updated March 4, 2004 as of this writing. The added material (now removed) was added on May 5, 2004 by Fratley. --Eequor 22:34, 29 May 2004 (UTC)

Hey, what a coincidence, I left the article alone for two years and now it is made up almost entirely of things other people plagiarized from other websites. Welcome to Wikipedia.

Anyway, I just removed three paragraphs taken word for word from a conspiracy website, of all things. You can find it at http://2012.com.au/SchumannResonance.html. If anyone has the patience to verify the contents and write something new about it, go ahead. --Fratley 14 July 2006

[edit] Tesla

I removed the half-sentence: but it was first observed by Nikola Tesla and formed the basis for his scheme for broadcast power and wireless communications.

As Tesla died 1943, it doesn't make much sense to me. If the resonance was observed by Tesla before 1943, how would it be possible for Schumann to first publish about it 1952 and event get it named after himself?

I don't know, but we've got a source. Perhaps he didn't realize the physical cause or perhaps his PR just wasn't good enough. Remember that the USA is not called the United States of Vinland. Shinobu 02:55, 1 November 2005 (UTC)

Nikola Tesla's 1899 discovery of VLF Earth-resonance was not accepted by the physics community of the time. Researchers believed that radio waves could not follow the curve of the Earth, therefore Tesla's results must be due to incompetence. As far as anyone knows, none of those physicists tested Tesla's claims (or had access to high-power VLF equipment which could replicate Tesla's experiments.) The scientific community also disbelieved Tesla's main goal of the time: to harness the VLF Earth-resonance effect and use it to transmit worldwide electrical power. As Tesla was outside of academia, and did not publish works in physics journals, and had recently claimed to have received intelligent broadcasts from outer space, this made the problem of disbelief far worse.--Wjbeaty 04:53, 1 November 2005 (UTC)

Yes, that will be the cause. I've seen this confirmed before, so maybe I should add it to the article. Shinobu 10:26, 2 November 2005 (UTC)

--Catblack 12:32, 4 May 2006 (UTC) Hey, I don't see anything backing up this statement:

Since the seventh overtone lies at approximately 60Hz, the cavity is also driven by the North American power grid.

Googling didn't help, and I think this statement is erroneous, as the 7th overtone is at 45 Hertz, not 60Mz. Anyone care to comment?

I once saw a paper on exactly this topic in a conference proceedings. If the 59Hz Schumann resonance (9th overtone) was being driven by the power grid, then there would be strong 60Hz fields in regions far from any power lines. And unlike a noise-driven resonance, phase of the 60Hz fields would be constant. The authors performed measurements in wilderness about 50 miles from power lines and found a strong constant-phase magnetic component at 60Hz. --Wjbeaty 18:45, 27 July 2006 (UTC)

In fact there seems to be a lot of claims and numbers thrown around in this article. Such as: "The resistance of the atmosphere is 200 ohms." I assume this is the resistance of the ionosphere, otherwise I'm never going near a power outlet again. Any references (besides Tesla) to back up? --Jquarry 01:27, 8 May 2006 (UTC)

otherwise I'm never going near a power outlet again. :-) Shinobu 16:45, 7 July 2006 (UTC)

[edit] north american power grid contributing to resonance

So I removed the sentence about a correspondence between the frequency of North American electricity - 60 Hz - contributing to Schumann Resonance because I looked around on the web and found nothing to back it up and it seemed false from the get go.

I added the frequencies of additional Schumann resonant peaks, as widely cited in academic papers online. —The preceding unsigned comment was added by 7thharmonic (talk • contribs).
