How REALITY REALLY is.

How REALITY REALLY is.

    In 1905 Albert Einstein published the Special Theory of Relativity. 

         He reshaped the world by revealing that the constant speed of light plays a major role in the reality of well    . . .   REALITY.  

Since speed is qualified as the distance an object travels over the amount of time it takes to travel that distance…

… the CONSTANT, UNCHANGING s p e e d of the photon...

  … means that  SPACE and TIME are actually fused together and they are the variables 

that adjust to life’s changing circumstances.

Consequences of this theory are:

    1.  TIME itself RUNS MORE SLOWLY FOR A PERSON WHO IS IN MOTION (TIME DILATION),
    2. The length of an object DEPENDS ON ITS SPEED WHEN YOU MEASURE IT. (LORENTZ CONTRACTION) and 
    3. the simultaneity of spatially separated events depend on the motion of the observer (THE ORDER OF EVENTS IS NOT ABSOLUTE).

None of the above consequences  feel like common sense or are obvious. In fact all of the consequences above seem very counter- intuitive to the way we see the world everyday. It is only because of the slow speeds we move here on earth that motion’s impact on time is so tiny that we don’t notice the effect of it.

Albert Einstein further revolutionized our world in 1915 when he generalized  his theory of special relativity and refined Newton’s law of universal gravitation to give us what is known as the GENERAL THEORY OF RELATIVITY. (This is the geometric theory of gravitation and the current description of gravitation in modern physics.)

The General Theory of Reality states (in a nutshell) that in the presence of mass and energy SPACE CURVES and that is what gravity IS.

  

In other words GRAVITY is something that emerges from the interaction of space and massive objects.

(This understanding of gravity was very different than what had been believed up until that time which was the Newtonian theory of physics : that time and space were FIXED and gravity was a magnetic force exerted BY objects ON other objects in proportion to their mass)

By the late 19th century the demand for electric lights was creating a mass market. In order to develop quality standards for the industry physicists were interested in the laws by which heated bodies emitted radiation. 

 

 

Classical physics assumed that as a body got hotter its radiation (in the form of light) also increased ↑. 

However this assumption could not X be confirmed  by any experiment and became a truly troubling problem for classical physicists….

Max Planck (born April 23 1858) was one of the theoretical physicists that was trying to explain the processes of radiation. He had grown frustrated by the problem and decided to throw out everything that he knew about light and start from scratch. 

 

He  worked backwards in a mathematical fashion and proposed that the radiation light emitted must not be emitted continuously but instead must be released in discrete packets of energy known as ‘quanta‘.  

To understand the term ‘quanta‘ better, imagine for a moment the radiation being emitted is like water…

Planck suggested that it (the radiation) could only be dispersed in droplets (QUANTA)

… as opposed to a stream ( or continuous flow).

A constant designated by the letter h (Planck’s constant) represented the ‘quanta’ and the total energy emitted from a system then could only  ever amount to a multiple of h

On December 14, 1900 experimental physicists were able to prove Plank’s Law of Radiation correct. Planck’s Law states that

 the Radiation energy = (Planck’s constant)h   x    the frequency of the radiation.

Planck’s constant was assigned a value  h = 6.62607015×10−34 J⋅Hz−1.

The total energy of the system then could only amount to a multiple of Plank’s ‘quanta’ of action.

With his new ‘quantum‘ of action Max Planck had unintentionally ushered in the age of a new kind of science: 

December 14,1900 went down in history as the BIRTH day of ‘QUANTUM PHYSICS‘.
