BBB Before the
Big Bang: In a vacuum state with no space and consequently no time,
physical laws would not seem appropriate. However, the law that
states matter can neither be created nor destroyed implies another
state of matter, i.e. a state of pure energy unbound by space and
time. The chance fluctuation indicated below for the beginning of
the Big Bang would have occurred in this energy field. This
occurrence could have been like the breaking of a dam, or a puncture
that explodes a filled tire, or a bomb that violently explodes upon
detonation. The resulting tiny bubble of space-time provided an
outlet for the enormous energy latent in the pre-space-time state.
This of course gives no account of how or where or why the initial
pure-energy state came about. We may never know, but we can always
speculate.

10-3 Sec Quarks freeze into particles. (JST-TMC,
1983, p.157) According to the Standard Theory, all matter in the
universe is made from different combinations of two types of
sub-atomic particles. Fermions, such as electrons and quarks, are
the bricks or fundamental building blocks of matter. A different
type of particle, called bosons, are the mortar. Bosons are the
carriers or forces like electromagnetism and gravity, which hold the
bricks of our universe together. Peter Higgs postulated around 1970
that the Higgs boson, usually invisible, creates a field through
which subatomic particles, such as quarks and electrons, pass.
Experiments in 2001 found that muon spin modification in a magnetic
field varied from that predicted by the Standard Model. When the
temperature dropped below 1 trillion degrees or so, the Higgs field
flipped on and some particles began interacting with Higgs bosons.
In 2012 Nicholas Mee authored “Higgs Force: The Symmetry-Breaking
Force That makes the World an Interesting Place. Jim Baggott
authored “The Quantum Story: A History in 40 Moments.”

490BC Empedocles (d.430BC), Greek philosopher, was
born. He is best known for being the originator of the cosmogenic
theory of the four classical elements. An important idea in ancient
Greek philosophy is that "Nothing comes from nothing", so that what
exists now has always existed, since no new matter can come into
existence where there was none before. An explicit statement of
this, along with the further principle that nothing can pass away
into nothing, is found in Empedocles (ca. 490–430 BCE): "For it is
impossible for anything to come to be from what is not, and it
cannot be brought about or heard of that what is should be utterly
destroyed."

1687 Jul 5, The first volume of
Isaac Newton's "Philosophiae naturalis principia mathematica"
("Mathematical Principles of Natural Philosophy") was published in
Latin by Edmund Halley. His invention of differential and integral
calculus is here presented. Here also are stated Newton’s laws of
motion, that obliterated the Aristotelian concept of inertia. 1)
Every physical body continues in its state of rest, unless it is
compelled to change that state by a force or forces impressed upon
it. 2) A change of motion is proportional to the force impressed
upon the body and is made in the direction of the straight line in
which the force is impressed. 3) To every action there is always
opposed an equal reaction. Book Three of the Principia opens with
two pages headed "Rules of Reasoning in Philosophy." There are four
rules as follows: 1) We are to admit no more causes of natural
things than such as are both true and sufficient to explain the
appearances. [A restatement of Ockham’s Razor: "What can be done
with fewer is done in vain with more."] 2) Therefore to the same
natural effects we must, as far as possible, assign the same causes.
3) The qualities of bodies which are found to belong to all bodies
within the reach of our experiments, are to be esteemed the
universal qualities of bodies whatsoever. 4) In experimental
philosophy we are to look upon propositions inferred by general
induction from phenomena as accurately or very nearly true
notwithstanding any contrary hypothesis that may be imagined, till
such time as other phenomena occur, by which they may either be made
more accurate, or liable to exceptions.

1905 Einstein presented his
theory of relativity declaring that the very measurement of time
intervals is affected by the motion of the observer. He proposed
that light is itself quantized, or particle-like, to explain how
electrons were emitted when light hit certain metals. He presented
four papers, the first on Brownian motion, the second was on the
composition of light, the third proposed the Special Theory of
Relativity, and the fourth established the equivalence of mass and
energy. Einstein presented 5 papers this year, one of which was
titled “Does the Inertia of a Body Depend on its Energy Content?”
This paper provided an incomplete proof of E=mc2, an equation that
had already been know for a few years. In 2008 Hans C. Ohanian
authored “Einstein’s Mistakes: The Human Failings of Genius.”

1908 Heike Kamerlingh-Onnes,
Dutch physicist, was the first to liquefy helium. He cooled helium

1927 Mar, J.W. Dunne
(1875-1949), Irish engineer and author, published his essay “An
Experiment with Time” on the subjects of precognition and the human
experience of time. His theory suggested that in reality all time is
eternally present, that is, that past, present and future are all
happening together in some way. Human consciousness, however,
experiences this simultaneity in linear form. It was very widely
read, and his ideas were later promoted by several other authors, in
particular by J. B. Priestley. Other books by J. W. Dunne are The
Serial Universe, The New Immortality, and Nothing Dies.

2019 May 20, Scientists, on the
occasion of World Metrology Day, adopted new hyper-accurate
definitions for units of weight, electricity and temperature derived
from the universal laws of Nature. The kilogram will now be defined
in terms of the Planck constant -- the ratio of a frequency of
light, on the one hand, to the quantum energy of that frequency, on
the other. Today also saw new definitions adopted for the ampere --
the rate of electrical current flow; the kelvin -- the base unit of
temperature; and the mole -- the unit measuring the amount of a
given substance.
