===========

a)*The fields / waves* extend over ALL space and time.
They don't live IN space and time like particles.
They are part of the fabric OF space and time.

b) There are ''ripples'' =** field quanta = "fundamental particles'' in these fields,
which have behavior constrained by symmetries of nature.

c) '' the idea of "things"/ particles moving through space and time
has become* REPLACED* with the idea of fields that extend everywhere,
and the ripples in them that are bestowed with small amounts of action.''

d) ''* . . . electromagnetic charge* is not some kind of "stuff" that belongs to
"things"; instead, charge is just defined as that tendency for a given
pair of fields to interact and create ripples in each other.
This idea needs more symmetries of nature (local gauge symmetries).''

e) ''What's astonishing about this is that physicists now believe that the
fundamental thing that physics is about is the interaction, not the object.
And rather than physical laws, physicists now think of symmetries as
the fundamental constraint. ''
* #
So, at first physicists use waves and math symmetries to understand situation.
And . . .** EM waves can create . . .* ''charge'', ''ripples'' / particles.
=====================

My opinion.
We don't drink H2O, We drink water, particles of water.
We cannot replace water on H2O and be quenched.

Oceanic waves consists of particles.
Without these particles we don't have waves / water.

The same story is with energy fields / EM waves.
Maxwell's EM waves and Lorentz electron /force are one complete theory.
Without electrons there aren't waves.
#
But until today we don't know what electron is.
We* don't know why the electron has six ( 6 ) formulas
* ** E=h*f** and** e^2=ah*c ,
* * +E=Mc^2** and** -E=Mc^2 ,
* ** E=-me^4/2h*^2= -13,6eV** and** E= ∞

An electron obey five Laws :
a) The Law of conservation and transformation energy/ mass
b) The Heisenberg Uncertainty Principle / Law
c) The Pauli Exclusion Principle/ Law
d) Dirac - Fermi statistic
e) Maxwell - Lorentz EM theory.

We don't know: what are interactions between these formulas and laws.
================================.
Robert A. Millikan, in his Nobel speech* ( 1923) said,
that he knew nothing about “ last essence of electron”
#
* Feynman wrote about electron :
“ It is important to realize that in physics today,
we have no knowledge of what energy is.
We do not have a picture that energy comes in little
blobs of a definite amount. “
===============

Therefore the situation with electron is similar to an old Indian story:
''what is an elephant ?''
One blind man touched the elephant’s foot and said elephant is like a column
Other blind man touched the elephant’s tail and said elephant looks like a snake
The third one touched the elephant’s stomach and said elephant is like a ball
The . . . . . . .. . .
=============.
The electron was '' touched''* in different experiments from different sides
but it seems that our knowledge of an electron is similar to the * blind – knowledge*
of elephant from this old Indian proverb.

As somebody wrote: ''We know electron by what it does, not by what it is''

It's all about waves, they may be perceived as particles, but that is perception, they are still waves.
That IS quantum mechanics.

Also, if you look closely, you might find the main equations in quantum mechanics are contained in the Yin Yang symbol.
;)
Of course, knowing THAT means you can never, ever be religious after that.
(religion was invented to blind you)

Energy can't be created or destroyed, only the way it is perceived changes.
Particles: pffft!, They are just from the brain creating your reality.

Particles are the Debble's[sic] playthings.

Quantum particles are sometime waves and sometime corpuscular.
That is like a cow that sometime gives milk and sometime beef.
That IS quantum mechanics.

Would that particle exist if there was no one there to 'see' it?

a) The* constant speed of photon* ( c= 299,792,458 km/ sec)* was observed
** in Michelson-Morley experiment*.

b) The virtual particles were showed their existence in the Casimir effect,
*in the Lamb shift in a vacuum fluctuation.

The Simple Idea Behind Einstein’s Greatest Discoveries
K.C. Cole
Contributing Writer
June 26, 2019
===
The relationship that eventually mattered most to Einstein’s legacy was symmetry.
Scientists often describe symmetries as changes
that don’t really change anything,
differences that don’t make a difference,
variations that leave deep relationships invariant.

Examples are easy to find in everyday life.
You can rotate a snowflake by 60 degrees and it will look the same.
You can switch places on a teeter-totter and not upset the balance.

More complicated symmetries have led physicists to the discovery
of everything from neutrinos to quarks — they even led to Einstein’s
own discovery that gravitation is the curvature of space-time,
which, we now know, can curl in on itself, pinching off into black holes.
#
Over the past several decades, some physicists have begun
to question whether focusing on symmetry is still as
productive as it used to be.
New particles predicted by theories based on symmetries
haven’t appeared in experiments as hoped, and the
Higgs boson that was detected was far too light to fit
into any known symmetrical scheme.
Symmetry hasn’t yet helped to explain why gravity is so weak,
why the vacuum energy is so small, or
why dark matter remains transparent.
#
“There has been, in particle physics, this prejudice
that symmetry is at the root of our description of nature,”
said the physicist Justin Khoury of the University
of Pennsylvania. “That idea has been extremely powerful.
But who knows?
Maybe we really have to give up on these beautiful and
cherished principles that have worked so well.
So it’s a very interesting time right now.”

'' Breaks in the Perfect Symmetry of the Universe
Could Be a Window Into Completely New Physics ''
By Paul Sutter, Astrophysicist
| June 14, 2019 06:59am ET

The bible of particle physics is dying for an upgrade.
And physicists may have just the thing:
Some particles and forces might look in the mirror and
not recognize themselves.
That, in itself, would send the so-called Standard Model into a tailspin.
. . .
. . . the weak nuclear force, violates parity symmetry.
So it stands to reason other forces and particles in the
quantum world are also rule-breakers in this area.

A butterfly has very beautiful symmetrical wings,
but it was created from caterpillar.

Concept of ''symmetry'' in physics is beautiful math,
but it doesn't reflect the whole picture of Nature.

Caterpillars are, of course, also symmetric.

Caterpillars are, of course, also symmetric if you slice them with a knife along the correct axis.
