We dwell in this world that he imagined, but we cannot see that. We experience the world he formulated, but we cannot fully sense that; we understand that Einstein said, "Everything has changed; except the way we think." Is it not time to start thinking more accurately about the universe. Can we not learn from his findings that on this Earth island we must not merely cherish, but nourish this oasis in the void of spacetime where a creature dared to ask, 'Do pardon me but are we residents in the Milky Way galaxy of this expanding universe?'

"what a light beam would look like if he could race alongside it."
One : Physics before Einstein
Simultaneity, instantaneous and absolute qualities of time and space were Newton's legacy.
"Newton could compute the trajectory of everything from falling leaves, soaring rockets, cannonballs, and clouds by adding up the forces acting on them. . . . it helped lay the foundation for the Industrial Revolution, where the power of steam engines driving huge locomotives and ships created new empires."
p. 24.
"This was the first explanation of the motion of the solar system."
"According to Newton, these forces act instantaneously."
p. 25.
"The completeness of Lord Kelvin's physics was based on the twin giants of physical thought Sir Isaac Newton and James Clerk Maxwell on the attraction of bodies to one another and over vast or proximate distances.
Electricity creates fields as well.
p. 27.
"If a changing magnetic field can create an electrical field and vice versa, then perhaps both of them can form a cyclical motion, with electrical fields and magnetic fields continually feeding off each other and turning into each other."
p. 28.
- Newton's gravity
- four of Maxwell's eight equations for electromagnetism
"Maxwell's work was codified in eight differential equations (known as 'Maxwell's equations'), which every electrical engineer physicist has had to memorize. . . . "
p. 29.
"These fields can be visualized by sprinkling iron filings on a sheet of paper. Place a magnet beneath the sheet of paper and the filings will magically rearrange themselves. . . . "
"Surrounding any magnet, therefore is a magnetic field, and invisible array of line of force penetrating all of space."
p. 27.
Fields
"Electricity creates fields as well."
"These fields, however, are quite different from the forces introduced by Newton. Forces, said Newton, act instantly all over space, so that a disturbance in one part of the universe would be felt instantly throughout all the universe."
"Maxwell's brilliant observation was that magnetic and electric effects do not travel instantaneously, like Newtonian forces, but take time and move at a definite velocity."
p. 27.
By 1900, the deficiencies of Newtonian mechanics were becoming harder and harder to explain. . . . That Newton's forces and and Maxwell's fields were incompatible. One of the two pillars of science must fall."
"Maxwell knew from the earlier work of Michael Faraday and others that a moving magnetic field can create and electric field and vice versa."
p. 28.
"these two great pillars of science had answered all the basic questions of the universe."
"There was nothing really new to be discovered . . . "
"Discoveries like Marie Curie's isolation of radium and radioactivity were rocking the world of science and catching the public imagination."
"She also showed that seemingly unlimited quantities of energy could come from an unknown source deep inside the atom, in defiance of the law of the conservation of energy, which states that energy cannot be created or destroyed."
p. 29.
Visualization of electromagnetic waves.
"Maxwell's theory confirmed that light was a wave, but that left open the question, what is waving?"
"Newtonian physics tried to answer this question by proposing that light consisted of waves vibrating in an invisible ‘aether’ a stationary gas that filled up the universe. The aether was supposed to be the absolute reference frame upon which one could measure all velocities."
" . . . the aether began to assume more and more magical and bizarre properties."
". . . sound waves travel faster in a denser medium."
". . . since light traveled at a fantastic velocity (186,000 miles per second), it meant that the aether must be incredibly dense to transmit light. But how could this be since aether was supposed to be lighter than air?"
Kaku, p. 30.
"Newton's forces and Maxwell's fields were incompatible. One of the two pillars of science must fall."
p. 31.

p. 64.
The speed of light is the same for all observers.
"Light velocity was the ultimate speed limit in the universe."
We never see the bizarre distortions in our experience because we never travel near the speed of light. For everyday velocities, Newton's laws are perfectly fine."

"Now physicists considered the total combined amount of matter and energy as being conserved."
"the photoelectric effect . . . . that if a light beam struck a metal, under certain circumstances a small electric current could be created."
"Einstein sought to explain the photoelectric effect by using the new 'quantum theory' recently discovered by Max Planck in Berlin in 1900."
" . . .one of the most radical departures from classical physics by assuming that energy was not a smooth quantity, like a liquid, but occurred in definite, discrete packets, called quanta. The energy of each quantum was proportional to its frequency."
In Einstein's "miracle year"from March to September he wrote four published papers; one of the four papers in 1905 was.
June 9, 1905 "On a Heuristic Point of View Concerning the Production and Transformation of Light."
"With it, the photon was born, as well as the quantum theory of light."
"This simple paper, in effect, gave the first experimental proof of the existence of atoms."
The suicide of Ludwig Boltzmann [believer in atomic theory]
"Einstein had finished the year 1905 laying down the photon theory, providing evidence for the existence of atoms, and toppling the framework of Newtonian physics, each of them worthy of . . . acclaim."

Quarks these are very minute subatomic particles dwelling within neutrons and protons that impart charge to these more massive sub-atomic particles. Six "flavors" of quarks exist in matter: Up, Down, Strange, Charm, Top and Bottom. Think of them as the six dwarves or gnomes inherent in material existence of fermions. Fermions include include electrons, protons, neutrons.

EPR is the initials standing for Einstein – Podolsky-Rosen thought experiment of two hypothetical electrons emitted from an atom traveling at the speed of light (where time stops). Where one electron spins in opposite angular momentum to its paired electron; such that the measure of one electron's spin reveals the other electron's spin even if is at the farthest reaches of the universe from where the measurement in taken.

Einstein's paper examined the kinetic theory of heat and predicted that small particles suspended in water must execute a random motion visible under the microscope. He suspects this motion is Brownian motion but has insufficient data to affirm it. The prediction is a powerful test of the truth of the kinetic theory of heat, and "in effect . . . the existence of atoms" [Kaku, E's Cosmos. p. 71] . A failure to observe the effect would refute the theory. If it is seen and measured, it provides a way to estimate Avogadro's number. The domain in which the effect is observed is one in which the second law of thermodynamics no longer holds, a disturbing result for the energeticists of the time.
"On the electrodynamics of moving bodies" (special relativity) (June 1905; received 30 June 1905) Annalen der Physik, 17 (1905), pp. 891-921.
Einstein explained the special theory of relativity in this paper. His concern, as he makes clear in the introduction, is that then current electrodynamics harbors a state of rest, the aether state of rest, and the theory gives very different accounts of electrodynamic processes at rest or moving in the ether. But experiments in electrodynamics and optic have provided no way to determine which is the ether state of rest of all inertial state of motion. Einstein shows that Maxwell-Lorentz electrodynamics has in fact always obeyed a principle of relativity of inertial motion. We just failed to notice it since we tacitly thought that space and time had Newtonian properties, not those of special relativity, thus dispensing with the idea of the aether.
"Does the inertia of a body depend on its energy content?" (E=mc2) (September 1905; received 27 September 1905) Annalen der Physik, 18 (1905), pp. 639-41.
Written as a brief follow-up to the special relativity paper, this short note derives the inertial of energy: all energy E also has an inertia E/c2; energy over or divided by the square of the speed of light.
