			Just as a tuning fork has natural 
			frequencies for sound, the planet Earth has natural frequencies, 
			called Schumann resonances, for electromagnetic radiation. The 
			Human Brain
			also has natural frequencies for electromagnetic radiation.
 
			It turns out that the Earth’s Schumann resonances are “in tune” with 
			the Human Brains’s Alpha States and Theta States.
 
 The fundamental frequency of the Schumann resonance is roughly the 
			fundamental frequency of a spherical shell whose inside boundary is 
			the surface of the Earth and whose outside boundary is the 
			ionosphere, acting as a spherical shell electromagnetic waveguide 
			cavity.
 
			The fundamental frequency ought to be roughly the time it takes 
			electromagnetic radiation to go all the way around the spherical 
			shell.
 
 Since the speed of light is about 300,000 km/sec and one cycle is 
			the circumference of the Earth, which is about 40,000 km/cycle the 
			fundamental frequency should be on the order
 
				
					
					of   300,000 km/sec________________  = 7.5 cycle/sec
 40,0000 km/cycle
 
			A cycle/sec is just a Hz, so that 7.5 
			cycle/sec is 7.5 Hz.  
			The Schumann Resonances are actually observed by experiment 
			to occur at several frequencies between 6 and 50 cycles per second; 
			specifically 7.8, 14, 20, 26, 33, 39 and 45 Hertz, with a daily 
			variation of about +/- 0.5 Hertz.
 
			The 7.8 Hz observed fundamental resonance is close to the rough 
			theoretical estimate of 7.5 Hz.
 
			So long as the properties of Earth’s electromagnetic cavity remains 
			about the same, these frequencies remain the same. The
			
			solar sunspot cycle may change the frequencies, because 
			the Earth’s ionosphere changes in response to the 11-year cycle of 
			solar activity.
 
			The fundamental frequency could be varied due to a number of things:
 
				
			 
			If you look at the interior of the 
			Earth, you see that there is a
			
			differential physical rotation of the solid 
			inner core with respect to the surface of the Earth. 
			However, it takes about 400 years for the inner core to make a 
			complete revolution inside the Earth, so that its frequency is only 
			one cycle per 400 years.  
			It is more interesting to look at the frequency of currents at the 
			boundary between the solid inner core and the liquid outer core. 
			Since the inner core has radius of about 1,200 kilometers, its 
			circumference is about 7,500 kilometers.
 
			How long would it take an electrical current, traveling at the speed 
			of light (300,000 km/sec), to go once around the circumference of 
			the inner core (7,500 km)?
 That is about 7,500 km / 300,000 km/sec, or 1/40 sec. In other 
			words, the natural frequency of the Earth at the boundary of the 
			inner core is about 40 cycles/sec, which is at the upper end of the 
			range of frequencies measured for the Schumann resonances: 7.8, 14, 
			20, 26, 33, 39 and 45 Hertz.
 
			Therefore, the Schumann resonance frequencies correspond to the 
			range of natural frequencies of the Earth from its surface to the 
			boundary of its solid inner core.
 
 Research on Schumann resonances is done by Dave Sentman and
			Matt Heavner in Alaska.
 
 The weakening of the Earth’s magnetic field over the past 2,000 
			years that has been observed may indicate the onset of another 
			magnetic field reversal. The last reversal of Earth’s magnetic field 
			was about 788,000 years ago.
 
 The map (taken from the cover of Nature, illustrating the article of 
			Lau, Mazaud, Weeks, Fuller, and Herrero-Bervera, Nature vol. 351 -6 
			June 1991- page 447) shows movement of virtual geomagnetic pole 
			(VGP) from its present position near the Earth’s axial north 
			pole during excursions and reversals that occurred about 120,000 
			years ago, about 1.8 million years ago, about 6.5 million years ago, 
			and about 11 million years ago.
 
			The VGP primarily moves between the Mid-Atlantic Ridge and the 
			Pacific West Coast of the Americas, but secondarily it moves along 
			the Asian Pacific Rim, and sometimes it seems to be located at the 
			antipodal area of the center of the Pacific Ocean, in the region of 
			Giza.
 
			Jim Branson has noted that 
			Schumann Resonance data from
			
			quake.geo.berkeley.edu show a daily 
			periodicity for the peaks of BT1 (North-South component) and BT2 
			(East-West component).
 
			The BT1 peaks (East-West Schumann component) seem to be when the 
			subsolar longitude (local noon) is about 8 hours west of Greenwich, 
			which is along the North American West Coast, where the tectonic 
			motion is North-South shearing.
 
			The BT2 peaks (North-South Schumann component) seem to be when the 
			subsolar longitude (local noon)  is about 2 hours west of 
			Greenwich, which is along the Mid-Atlantic Ridge, where the tectonic 
			motion is East-West spreading.
 
 Therefore, the BT1 and BT2 peak longitudes seem to mark the 
			boundaries of the primary zone of VGP movement during geomagnetic 
			excursions and reversals.
 
 The natural frequencies of the
			
			Human Brain are:
 
				
					
					
					Beta waves (14 to 30 Hz)
					
					Alpha waves (8 to 13 Hz)
					
					Theta waves (4 to 7 Hz)
					
					Delta waves (1 to 3 Hz) 
			Alpha frequencies have been associated 
			with meditation and relaxation. Theta frequencies have been 
			associated with a dreamy, creative states. 
 According to a web page related to an October 2002 Physics News 
			Update:
 
				
				“...EEGs can now record brainwaves 
				without the need for electrodes to be inserted into the brain or 
				even for them to be placed on the scalp. The figure shows a 
				brainwave trace for periods when the eyes are open and when they 
				are closed. 
				The red regions respond to the alpha wave (eyes closed) at a 
				frequency of around 9 Hz. (Courtesy University of Sussex) ...”.
 
			The Beta and Alpha waves 
			(8 to 30 Hz) seem to correspond to the Schumann resonances: 7.8, 14, 
			20, 26, 33, 39 and 45 Hertz. The 30 Hz high end of the Beta waves is 
			roughly coincident with the frequency of cats’ purrs:  
				
				According to an 18 March 2001 
				article in the London Telegraph by David Harrison: 
				“... the purring of cats is a 'natural healing mechanism'... 
				between 27 and 44 hertz... was the dominant frequency for a 
				house cat, and 20-50Hz for the puma, ocelot, serval, cheetah and 
				caracal. This reinforces studies confirming that exposure to 
				frequencies of 20-50Hz strengthens human bones and helps them to 
				grow... Almost all cats purr, including lions and cheetahs, 
				though not tigers...”   
				However, according to a Bengal 
				Tiger web page: “...[Bengal] tigers purr. Domestic cats purr 
				when breathing in and out - tigers purr only when [breathing] 
				out... the roar of a Bengal tiger can be heard 2 miles away... 
				the Siberian tiger, a cousin of the Bengal tiger, is the world’s 
				largest cat...” 
			What about the Theta and Delta Waves (1 
			to 7 Hz)?  
			The 1 Hz frequency of the Delta waves is 7.5 times lower than the 
			7.5 Hz natural frequency at the surface of the Earth. Since the 
			radius of the Earth is about 6,400 km, the radius for a 1 Hz natural 
			frequency is about 7.5 x 6,400 = 48,000 km.
 
 Here are some natural frequencies that seem to correspond to the 
			Delta and Theta waves of the Human Brain.
 
				
					
					
					Plasma Sheet (opposite Sun), 
					inner radius = 60,000 km 0.8 Hz
					
					Magnetopause (toward Sun), 
					radius = 60,000 km 0.8 Hz 
					
					Geosynchronous orbit, radius = 
					35,000 km 1.4 Hz
					
					Outer Van Allen electron belt, 
					outer radius = 25,000 km 2 Hz 
					
					Inner Van Allen proton belt, 
					outer radius = 12,000 km 4 Hz 
					
					Inner Van Allen proton belt, 
					inner radius = 8,400 km 5.7 Hz  
			As to the following frequencies:  
				
					
					
					Magnetopause (opposite Sun), 
					radius = 380,000 km 0.125 Hz 
					
					Plasma Sheet (opposite Sun), 
					outer radius = 380,000 km 0.125 Hz 
					
					Moon orbit, radius = 384,000 km 
					0.125 Hz 
			It is interesting that 0.125 Hz is about 
			8 seconds per cycle, which is roughly the same period as the 5 
			second delay that has been observed between the onset of a 1 to 2 
			millitesla magnetic field (about 100 times stronger than Earth’s 
			magnetic field) and the first bursts of brain activity responding to 
			the magnetic field. (See Science 260-1590 - 11 June 1993)
 
 Low-frequency electromagnetic waves of humans may be associated with 
			Qi. If so, Qi may be detectable physically.
 
 The
			
			Qi Field is one of the promising 
			New Technologies. The microtubule structure of brains and other 
			cells may be the key to phenomena such as consciousness.
 
 Human brain wave activity can be compared to that of Dolphins. Some 
			experiments show connections between the brain states and resonant 
			electromagnetic waves, raising the possibility that the Human Brain 
			has evolved to be “in tune” with Planet Earth.
 
 Dolphin and Human Brains may contain
			
			BioMagnetite that could give them 
			an electromagnetic sense that could provide a link between Brains 
			and many types of electromagnetic phenomena, including but not 
			limited to Schumann Resonance Phenomena.
 
 Steve Mizrach (Seeker1) has web pages that describe Mind 
			Machines, or devices that affect state of mind by stimuli such as 
			light, sound, electricity, and chemicals. Dave Siever (Comptronic 
			Devices) has web pages that describe some of the history of mind 
			stimulation by light and sound. An example of mind stimulation by 
			light is part of the initiation ceremony of Zoroastrianism.
 
			Some of these matters were dealt with in the Tucson Conferences in 
			1994 and 1996 on the phenomena of consciousness. A third Tucson 
			Conference is planned for 1998.
