In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold M using partial differential equations.The key observation is that, given a Riemannian metric on M, every cohomology class has a canonical representative, a differential form that vanishes under the Laplacian operator of the metric.

[ 15 ] On April 15, 2014, the Phillips family's ex-nanny filed a lawsuit against Phillips and Vision Forum, alleging that she had suffered years of sexual abuse at the hands of Doug Phillips.
Harmonic analysis is a branch of mathematics concerned with investigating the connections between a function and its representation in frequency.The frequency representation is found by using the Fourier transform for functions on unbounded domains such as the full real line or by Fourier series for functions on bounded domains, especially periodic functions on finite intervals.
Sympathetic resonance or sympathetic vibration is a harmonic phenomenon wherein a passive string or vibratory body responds to external vibrations to which it has a harmonic likeness. [1] The classic example is demonstrated with two similarly-tuned tuning forks. When one fork is struck and held near the other, vibrations are induced in the ...
The Harmonic Convergence was the world's first synchronized global peace meditation, coinciding with an exceptional alignment of Solar System planets on August 16–17, 1987. The event was organized by spouses José Argüelles and Lloydine Burris Argüelles, via the Planet Art Network (PAN), a peace movement they founded in 1983.
