@Jasper10,
I maintain that science is symmetrical.It is not unsymmetrical.
I maintain that the brain utilises the symmetrically balanced + and - electromagnetic forces in its construction.The science behind this being the symmetrically balanced philosophical logic +/-=+/-
I maintain that this is the reason why electrical signals within the brain are sinusoidal in nature.They oscillate because they are passing through vibrating electromagnetic fields due to the above formula.
If you are upset by this remember the above is merely and alternative view of science based upon an alternative philosophy that cannot be challenged.
