Existence is an impurity in an otherwise beautifully simple universe.
…………………………………………
Science reminds us to be grateful for what we have. If the universe were only minutely more symmetric than the one we inhabit, it would have collapsed before it began.

“It is only slightly overstating the case to say that physics is the study of symmetry.”
-Phil Anderson
…………………………………………

“A thing is symmetrical if there is something you can do to it so that after you have finished doing it, it looks the same as before.”
-Hermann Weyl
…………………………………………

We are asymmetric lumps that ruin the otherwise perfect symmetry of the cosmos.
…………………………………………
Our sense of symmetry (Laws of the universe are the same everywhere in space and time ) helped us discover  Newton’s first law of motion (An object in motion stays in motion) and first law of thermodynamics (the conservation of energy).

“Everything is kinda the same? Every Friday night is like every other one? Sounds almost comforting. But it would be a mistake to be comforted by the symmetries of the universe. In truth, they are your worst enemies. Everything we know about those rational, predictable arrangements dictates that you shouldn’t be here at all.”
-Phil Anderson
…………………………………………

Quantum gravity has no  global symmetry. 

……………………………………..

Quantum field theory’s quantum fields permeate the Universe and their excitations are ‘felt’ by us  as fundamental particles.

General Relativity’s spacetime describes  how every quantum of matter and energy moves through the Universe and spacetime curvature is ‘felt’ by us as gravity.

……………………………………..

Our memetic models of reality can be improved indefinitely until we get a theory of everything i.e. an all encompassing meme.

Supersymmetric confinement represents nothingness. Symmetry breaks to infinity. A cabbage takes smaller volume than its torn foliage.

……………………………………..

 

Sub-atomic particles do not behave the same way when their orientations are flipped into their mirror images. It is a breaking of mirror or “parity” symmetry.

…………………………………………

Perhaps we need  invisible mirror image particles to initially get the real symmetry to explain sub-atomic particles’  mirror symmetry breaking.

…………………………………………

Neutrons in a magnetic field decay sooner than ones in a beam created from a nuclear reactor.

Substances on Earth can exist in one of four phases: solid, liquid, gas or plasma.

…………………………………………

Six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.

…………………………………………

Sublimation is changing directly from a solid to a gas without going through the liquid phase.

…………………………………………

Deposition is  changing directly from a gas to a solid without going through the liquid phase.
…………………………………………

Water vapor turning to frost is an example of deposition.
…………………………………………

Freezing is when liquid water freezes into ice cubes.
…………………………………………

Melting is when those ice cubes melt.
…………………………………………

Condensation is when dew forms on grass in the morning.
…………………………………………

Vaporization is when water boils and turns into steam.

…………………………………………

Deposition is one you may not know, but this happens when water vapor goes directly to freezing, like when there is frost on a cold winter morning.

…………………………………………

Sublimation happens when dry ice turns directly into gas.
…………………………………………

Gas can also change into a plasma if we can  add an enormous amount of energy to the gas in order to free up the electrons from the atoms.

…………………………………………

…………………………………………

Water is more symmetric than ice.

…………………………………………

Dihedral angle is the upward angle(between 60° and 120°) from horizontal of the wings. Anhedral angle”  is negative dihedral angle.
…………………………………………
Symmetry can be regarded as a resource in the teaching of  biology and geometry since  children up to the age of seven spontaneously use symmetries to draw the plant world.

…………………………………………

Cyclic symmetry  represents rotational symmetry around a central point.This symmetry is used to draw the sun.
…………………………………………

Dihedral symmetry  includes both rotational symmetry and reflection symmetry. This symmetry is used to draw the plant world, people and  decorative elements such as stars or hearts.
…………………………………………
Girls use complex symmetries more frequently than boys.
