How the Natural World has Been Painted

While some are intrigued by EM waves, I have a fascination for GW and the way we can portrait the natural world, we do not see.

See:Lisa Images

The sounds of gravitational waves are probably too low for us to actually hear. However, the signals that scientists hope to measure with LISA and other gravitational wave detectors are best described as "sounds." If we could hear them, here are some of the possible sounds of a gravitational wave generated by the movement of a small body in spiralling into a black hole.

There is a lesson in this, when you learn to hear what billiard balls sound like, and what the resulting ""click" could represent.

Savas Dimopoulos

Here’s an analogy to understand this: imagine that our universe is a two-dimensional pool table, which you look down on from the third spatial dimension. When the billiard balls collide on the table, they scatter into new trajectories across the surface. But we also hear the click of sound as they impact: that’s collision energy being radiated into a third dimension above and beyond the surface. In this picture, the billiard balls are like protons and neutrons, and the sound wave behaves like the graviton.

It helps you to see the world as a very much different place then the one we are accustomed too.

Can these be applied to such romantic reasoning, that we are encouraged to poetry and other things, where such idealizations, are battling for whose interpretation is right? What portraits are these that there is no romm for them to hang for observation? A glimpse of Mona Lisa's smile, that if taken from various perspective it would seem to be always looking at you? How could you distance yourself, if you are what you think?

Quantum Gravity

The jump from conventional field theories of point-like objects to a theory of one-dimensional objects has striking implications. The vibration spectrum of the string contains a massless spin-2 particle: the graviton. Its long wavelength interactions are described by Einstein's theory of General Relativity. Thus General Relativity may be viewed as a prediction of string theory!

Imagine the very canvas is string theories very fabric of the cosmos:)

This is a visualization of a simulation of a two-dimensional simplicial quantum gravity model. The surface is a dynamical triangulation, that is, as the simulation progresses, the way that the vertices of the triangular lattice are connected is constantly changing.

When the simulation began, we started with a lattice made of just four triangles, or simplices. Immediately, the computer began building the lattice up by, at random, choosing a triangle, putting a new point in the center and connecting the new point to the corners of the old triangle. Then there were three triangles where there was previously only one. This process was repeated until the lattice contained 30 points and 56 triangles.

"Dynamical triangulations" and such, that such a painting will explore the greater potential of perception, from varying perspectives?

The French mathematician Henri Poincaré provided inspiration for both Einstein and Picasso. Einstein read Poincaré's Science and Hypothesis (French edition 1902, German translation 1904) and discussed it with his friends in Bern. He might also have read Poincaré's 1898 article on the measurement of time, in which the synchronization of clocks was discussed--a topic of professional interest to Einstein as a patent examiner. Picasso learned about Science and Hypothesis indirectly through Maurice Princet, an insurance actuary who explained the new geometry to Picasso and his friends in Paris. At that time there was considerable popular fascination with the idea of a fourth spatial dimension, thought by some to be the home of spirits, conceived by others as an "astral plane" where one can see all sides of an object at once. The British novelist H. G. Wells caused a sensation with his book The Time Machine (1895, French translation in a popular magazine 1898-99), where the fourth dimension was time, not space.

Ps: Please note that some things have been added from the original post to illustrate the idea in terms of "the background" and how this is interpreted in the senses, as a much wider understanding of Gravity in respect used here in the Library.
