The Sound of Two Black Holes Colliding

Audio Credit: Caltech/MIT/LIGO Lab  As the black holes spiral closer and closer in together, the frequency of the gravitational waves increases. Scientists call these sounds “chirps,” because some events that generate gravitation waves would sound like a bird’s chirp. See: … Continue reading

The Map of B Mode Imprints

Figure 3: Left: BICEP2 apodized E-mode and B-mode maps filtered to 50 < ℓ < 120. Right: The equivalent maps for the first of the lensed-ΛCDM+noise simulations. The color scale displays the E-mode scalar and B-mode pseudoscalar patterns while the lines display the equivalent … Continue reading

Weber Bars Ring True?

Gravitational Radiation Gravitational waves have a polarization pattern that causes objects to expand in one direction, while contracting in the perpendicular direction. That is, they have spin two. This is because gravity waves are fluctuations in the tensorial metric of … Continue reading

New Synesthete Character on Heroes

For example, in 1704 Sir Isaac Newton struggled to devise mathematical formulas to equate the vibrational frequency of sound waves with a corresponding wavelength of light. He failed to find his hoped-for translation algorithm, but the idea of correspondence took … Continue reading

Gravity Wave Spectrum

PURPOSE: To show the two-dimensional standing waves on the surface of a square or circular plate. Early perception of sound as analogy to the ideas of the WMAP background were forming in my mind when Wayne HU was demonstrating the … Continue reading

Loosing Sight of Discrete Geometry

Discrete mathematics, also called finite mathematics or decision mathematics, is the study of mathematical structures that are fundamentally discrete in the sense of not supporting or requiring the notion of continuity. Objects studied in finite mathematics are largely countable sets … Continue reading
