Matter. Before the 20th century, the term matter included ordinary matter composed of atoms and excluded other energy phenomena such as light or sound.

Matter

This concept of matter may be generalized from atoms to include any objects having mass even when at rest, but this is ill-defined because an object's mass can arise from its (possibly massless) constituents' motion and interaction energies. Thus, matter does not have a universal definition, nor is it a fundamental concept in physics today. Matter is also used loosely as a general term for the substance that makes up all observable physical objects.[1][2] All the objects from everyday life that we can bump into, touch or squeeze are composed of atoms. This atomic matter is in turn made up of interacting subatomic particles—usually a nucleus of protons and neutrons, and a cloud of orbiting electrons.[3][4] Typically, science considers these composite particles matter because they have both rest mass and volume.

" said Dick Vane-Wright, the Keeper of Entomology at the London Museum of Natural History when author Sharman Apt Russell was asking about butterflies. "You could spend a week studying some obscure insect and you would then know more than anyone else on the planet. Our ignorance is profound. " Russell was so inspired by this conversation—which appears in her book Diary of a Citizen Scientist (read an excerpt published by Orion Magazine)—that she became an expert on tiger beetles.

" In the early 1980s, astronomer Carl Sagan hosted and narrated a 13-part television series called "Cosmos" that aired on PBS. On the show, Sagan thoroughly explained many science-related topics, including Earth's history, evolution, the origin of life and the solar system. "We are a way for the universe to know itself.

Our World Physical realism is the view that the physical world we see is real and exists by itself, alone.

10 Reasons Why Our Universe Is A Virtual Reality

Most people think this is self-evident, but physical realism has been struggling with the facts of physics for some time now. The paradoxes that baffled physics last century still baffle it today, and its great hopes of string theory and supersymmetry aren’t leading anywhere. Fractal Universe. The Daily Galaxy. In February, 1971, Apollo 14 astronaut Edgar Mitchell experienced the little understood phenomenon sometimes called the “Overview Effect”.

The Daily Galaxy

He describes being completely engulfed by a profound sense of universal connectedness. Without warning, he says, a feeing of bliss, timelessness, and connectedness began to overwhelm him. He describes becoming instantly and profoundly aware that each of his constituent atoms were connected to the fragile planet he saw in the window and to every other atom in the Universe.

Gini coefficient

This is based on 1989 to 2009 data, estimated by the CIA. Some are pre-tax and transfer, others post-tax income. The Gini coefficient (also known as the Gini index or Gini ratio) (/dʒini/) is a measure of statistical dispersion intended to represent the income distribution of a nation's residents. It was developed by the Italian statistician and sociologist Corrado Gini and published in his 1912 paper "Variability and Mutability" (Italian: Variabilità e mutabilità).[1][2] The Gini coefficient measures the inequality among values of a frequency distribution (for example levels of income).

There are some issues in interpreting a Gini coefficient. Definition[edit] Graphical representation of the Gini coefficient The graph shows that the Gini coefficient is equal to the area marked A divided by the sum of the areas marked A and B. that is, Gini = A / (A + B).
