Introduction To Quantum No Jargons

In Astrophysics on April 10, 2014 at 11:42

I was a Speaker in a Function marking the occasion of the release of a Research Book “Downloading Nature‘s Secrets,From Akasa to Quantum Vacuum

Field by Sri.Lakshminarayananan Gopalan in Chennai on the Fifth of April 2014.

 

The book deals with the inadequacy of the present day Science, how the Vedas have anticipated these issues and how the Gayatri Mantra  unlocks these secrets.

 

 

 

 

 

 

Quantum explained with Light

Are these beams of light over Sydney, Australia made of particles or waves? The true physical nature of light had been debated for years. Planck and others showed that not only light but all matter exhibited properties of both a particle and a wave.(Cameron Spencer/Getty Images)

 

 

Chart of Quantum Theory

Quantum Theory in Chart

I shall be posting on this shortly.

 

Science, as we know , rests on certain Laws, which are assumed to be true,called Axioms.

 

These laws under strict laboratory identical conditions will operate and the same Cause will produce the same result.

 

The problem is you produce the conditions obtaining in Nature and you repeat them to produce the result, which obviously has to produce the same result.

 

In other words, Science tells you How and never Why.

 

But it assumes that it is final.

 

When you can not describe or define Why , your word is not final.

 

This applies to Science .

 

Let us take the Laws of Newton.

 

I shall not be discussing the exact definitions as it would be beyond the scope of this essay.

 

I shall deal with it later.

 

An object remains Inert until it is impelled by an External Force.

 

From where does this external force come ?

 

No answer.

 

If it is assumed that it is in the Nature of things, as Axioms, then you are not solving the issue, but are ducking it and you are offering the Mechanics of Motion, that’s all.

 

In my view this does not matter, as it does not tell me any thing new in terms of my inquiry content.

 

 

For the average person, whether we know how a Thing moves does not matter so long it moves.

 

Things were falling to the ground even before Newton discovered Gravity.

 

Even if we are blissfully unaware of it , still Gravity would function.

 

 

However these theories have their uses in that these help in developing technologies that help(?) Man.

 

The second law that the rate of Momentum being directly proportionate to the force applied is also thrown out of this discussion as the first law on which this is derived from is not answering the question.

 

The same to the Third Law of Motion.

 

Science also harbors under the strain of Space and Time.

 

Unless we understand Space and Time we may not be able to understand the Laws of Nature and These terms Space and Time remain undefined till date.

 

At best, there are only descriptions and that too are being contradicted more or less on a daily basis.

 

As Emmanuel Kant put it,”Space and Time are the Two goggles through which Man perceives” Remove these,you can not conceive of anything , let alone perceive!

 

Coming back to the Theory of Motion, we now have research going on in CERN, Geneva, to find the God Particle.

 

As we all know the Atom consists of Electrons, Protons and Neutron.

 

Electrons and protons move around the Neutron. Now, when an object moves it creates energy.

 

So where do the Energies from these electrons and protons go?

 

Again, the movement of these seem to be directed.

 

Scientist want to find it as they have theoretically found that there must be some particle or force that directs these electrons and protons .

 

So the search goes on. Now apply this to the Movement of galaxies that spins and move, The same Laws apply.

 

And there is is this Theory of Expanding Universe which states that the Universe is expanding with each object in the Universe hurling away from each other and this has been proved by the Infrared shift of the Spectrum.

 

If these things keep on moving away from each other, where is does it end?

 

Where is the Edge of the Universe? Einstein tried to solve this through he general Theory of Relativity.

 

Appropriate at this point,  is that the Space and Time  become One Universe at one point  and that Time can travel both forwards and backwards.

 

And it can recoil on it self and there are Time Worms.

 

Then we have the Black-holes, which are assumed not to let even light rays to escape from it.

 

And Time runs backwards there and, theoretically if one were to enter a Black-hole, he might enter the Past travel through the Future and emerge in the Present!

 

And this gives rise, along with the effort to find the God particle leads us to Quantum Theory and Multi verses.

Indian Thoughts, Advanced Modern Concepts

In Indian Philosophy, Science on June 8, 2013 at 10:27

We live in a Technological Age.

Whatever Theories have been formed they find expression in Technology.

Technology is so advanced that we are in fact of theories to support them!

Yet some of the Theories in Science need further examination and updating

Indian Philosophy has crossed this barrier thousands of years back and some of the Theories which we use now had ben used by them and were developed further,

(Note. In India, we use the term Philosophy in the broadest sense ,that is to know, to be aware of;Science is included in this)

But then there have been claims often that ’this is in Indian Philosophy,the finding is not new’.

This statement has been repeated ad nausea that people have started ridiculing these assertions.

We shall examine some of the Theories of Indian Philosophy and their relevance to modern Scientific Thought.

( When we say Indian Philosophy, it includes all systems of Thought ,Buddhism,Jainism,Sankhya,Nihilism,Atheism)

To begin with take the fundamental of Science.

The essentials of Science rest on two Axioms.

a)Law of Uniformity of Nature and

b)Theory of cause and Effect

Modern Physics , till recently, has been so rigid in its assertion that the laws of Physics are Universal and apply to the Universe.

Now they have revised their opinion.

They have come to the conclusion that the Physical laws that exist in our plane of existence may not be true or applicable to other levels.

The Quantum theory supports this view and the Theory also lends evidence to the existence of other universe at the other planes that exist simultaneously!

How does Indian Philosophy look at this problem , what is its stand on this and how does it explain these phenomena?

Indian Philosophy confirms the existence of 14 present Universes in our plane and more in other planes.

Modern Physics has proved,albeit theoretically, the existence of 11 planes that exist in different co ordinates.

We shall examine this .

2.Mathematics and Time .

Those who are keeping tabs of modern physics are aware that Time Travel is theoretically possible, though modern physics can not reconcile certain facts.

Those who have read Isaac Asimov’s “Eternity’ and seen some of the Hollywood Films on Time,like The Moth man Prophecy (based on True life story),’Next’ will know that by extending the Logic of these films which are correct any way), one can see the contradiction.

If one were to travel back in Time , meet his self at that point of time and kills him /kill his mother ,Grand mother before (the man in who travelled to the past) before they were responsible e for his birth, what happens to his existence now?

If Time travel is possible, we can also alter Time.

When we alter Time we are altering Events which have happened already.

If we alter them now, what happens to the Events that have taken place?

Take the general Theory of Relativity.

Einstein’s Theory states Light is the fastest traveling medium .

During his Time it was proved that there are particles that travel faster than Light.

Einstein replied that if they travel faster than the Velocity of Light, they no longer remain Matter!

The what is Matter?

Also note the Principles of Motion by Newton.

Newton uses the term velocity to indicate Speed as Speed can have negative integers, namely Positive and Negative.

How does a common Mind accept this?

And if we cover distances swiftly by travelling fast, then theoretically at least, at some velocity, we should be reaching the Destination before we left!

Motion is movement from One point to another, right.

Science axiom state that Space infinitely divisible.

So Motion will be covering infinite Space.

That means Motion is impossible!

Hoe does Indian Thought solve this problem?

By The Non Linear Theory of Time.

We shall deal with this, the concept of other Universes, The Concept of Infinity and Zero.

………….                                               To be continued

What if some kills himself/Father /Mother by going back in Time, what happens to his Existence?

Does he exist or not?

Physicists, based on Quantum Mechanics , declare that our Universal Laws do not apply to things /Events existing at other planes.

Hinduism and Science.

Science and Hinduism

Are there other planes of existence?

Do Multiverses exist as proved by The Quantum Theory?

What is Theory of Evolution of The Universe?

Did they anticipate Electric lights?

What is Infinity and are there particles that travel faster than Light?

Modern Science measures astronomical distances with the Unit of Light.

Is it the correct way or are there better ways?

What exactly is Sound?

How does a language affect one’s Life?

What exactly is Magnetism?

Did people know how to travel in Space?

If so,did they have a Craft and design and how was it fuelled?

Did our ancestors develop Weapons of Mass Destruction(WMD)?

How does it compare with Hydrogen,Atom and Neutron Bombs?

Or did they have Cluster Bombs and nerve gas ?

Did they possess the skills of Clairvoyance,Clairaudience,Telepathy and Kinetasis?

To which Level had they evolved in terms of Military Strategy and battle Formations?

Test Tube babies-are they Modern developments?

Were they aware of Organ Transplants?

Were there aware Stem Cell Research and rejuvenation of dead Organs?

What is their view od Brain Death?

What about Genealogy ?

What are X and Y chromosomes?

Nan we predict the days on which you can have sexual inter course to beget a child of your choice?

Or what did they know of Consciousness and were there any records of “Near Death Experiences?

Did they know about the Organisation of Organisation Structure?

Were there any concepts that prove the Axioms of Science?

Did they have a system of Logic which overtakes the Logical Positivism of Bertrand Russell?

Have they developed the best language for Computer?

We shall in a Series of articles examine these thoughts and some more interesting points.

The examination will not be in “ we told you so’ mode but an exposition of facts taken from our Texts ,

The Vedas,

The Ramayana, of Valmiki

Adhyatma Ramayana

The Mahabharata,

Yoga Sutras of Patanjali

Nyya Vaasishtam by Vasishta.

Asthavakra Samhita

And many more and they will be referred to as and when required.

The Vishnu Purana .

Bhavishya Purana.

Kalki Purana.

Brahmanada Purana.

Saptha Bhangi Naya of Jainism.

Vigyana Vada of Buddhism.

Purva Mimaamsa

The Upanishads.

We will examine them and interpret them in the language of Modern Physics.

We would also predict the route Modern Science will take or ought to take and the results they are likely to get.

Gravity Assumptions Galore.

In Astrophysics, Society on December 31, 2012 at 11:48

Gravity is the Force that appears to attract Physical Bodies towards each other’.

Let’s see how much we know about it.

 

Note the Definition, ‘appears to attract’ – We are not sure.

 

Einstein’s Views -‘Theory of  General Relativity‘ as applied to Gravity.

 

Space and Time , Spacetime condition Gravity.

 

General relativity, or the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1916[1] and the current description of gravitation in modern physics. General relativity generalises special relativity and Newton’s law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations.”…

 

Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light. Examples of such differences include gravitational time dilationgravitational lensing, the gravitational redshift of light, and the gravitational time delay. The predictions of general relativity have been confirmed in all observations and experiments to date. Although general relativity is not the only relativistic theory of gravity, it is the simplest theory that is consistent with experimental data. However, unanswered questions remain, the most fundamental being how general relativity can be reconciled with the laws of quantum physics to produce a complete and self-consistent theory of quantum gravity.

Space is curved(please read my blogs under Astrophysics).

 

Have we defined Space, Tie?

 

No.

 

Consequently Gravitation as influenced by Spacetime,at best, remains a conjecture.

 

Space time and Gravitation

Two-dimensional analogy of spacetime distortion generated by the mass of an object. Matter changes the geometry of spacetime, this (curved) geometry being interpreted as gravity. White lines do not represent the curvature of space but instead represent the coordinate system imposed on the curved spacetime, which would be rectilinear in a flat spacetime.

 

Newton on Gravity(theory discared, yet being used in Calculations)

 

” “I deduced that the forces which keep the planets in their orbs must [be] reciprocally as the squares of their distances from the centers about which they revolve: and thereby compared the force requisite to keep the Moon in her Orb with the force of gravity at the surface of the Earth; and found them answer pretty nearly’…

 

Although Newton’s theory has been superseded, most modern non-relativistic gravitational calculations are still made using Newton’s theory because it is a much simpler theory to work with than general relativity, and gives sufficiently accurate results for most applications involving sufficiently small masses, speeds and energies.’

 

Irrespective of the fact whether our Theory is Right or Wrong, Principles of Nature work,so much for Science.

 

By the way , can some one forward me the exact definition of Nature?

 

Earth’s Gravity.

 

a) Earth is ‘assumed’ to be surrounded by its own Gravitational Filed, which exerts an attractive force on all objects. Assuming a spherically symmetrical planet, the strength of this field at any given point is proportional to the planetary body’s mass and inversely proportional to the square of the distance from the center of the body….

 

The fundamental is an Assumption.

 

Again, ‘ This means that, ignoring air resistance, an object falling freely near the Earth’s surface increases its velocity by 9.81 m/s (32.2 ft/s or 22 mph) for each second of its descent. Thus, an object starting from rest will attain a velocity of 9.81 m/s (32.2 ft/s) after one second, 19.62 m/s (64.4 ft/s) after two seconds, and so on, adding 9.81 m/s (32.2 ft/s) to each resulting velocity. Also, again ignoring air resistance, any and all objects, when dropped from the same height, will hit the ground at the same time.

 

Assumptions.

 

‘The strength of the gravitational field is numerically equal to the acceleration of objects under its influence, and its value at the Earth’s surface, denoted g, is approximately expressed below as thestandard average.

g = 9.81 m/s2 = 32.2 ft/s2′

We want to know Earth’s Gravitation, that is what we want to prove.

Acceleration of Bodies is determined the force of Gravitation.

So when we rely on the Acceleration of Objects under the influence of the Earths’ gravitation , have we not already assumed Earth’s  Gravity?

We also ignore the effect of Electromagnetism and other forces at work,EM being dependent on Gravitation or is the other way around?

The Theory is riddled with Assumptions and leaping to conclusions.

http://en.wikipedia.org/wiki/Gravitation#Newton.27s_theory_of_gravitation

 

Chinese Scientists have found a way to measure Gravity and it throws Spanner in the works.

 

‘By conducting six observations of total and annular solar eclipses, as well as Earth tides, a team headed by Tang Keyun, a researcher with the Institute of Geology and Geophysics under the Chinese Academy of Sciences (CAS), found that the Newtonian Earth tide formula includes a factor related to the propagation of gravity.

“Earth tide” refers to a small change in the Earth’s surface caused by the gravity of the moon and sun.

Based on the data, the team, with the participation of the China Earthquake Administration and the University of the CAS, found that gravitational force released from the sun and gravitational force recorded at ground stations on Earth did not travel at the same speed, with the time difference exactly the same as the time it takes for light to travel from the sun to observation stations on Earth.

[…] By applying the new data to the propagation equation of gravity, the team found that the speed of gravity is about 0.93 to 1.05 times the speed of light with a relative error of about 5 percent, providing the first set of strong evidence showing that gravity travels at the speed of light.”

String theory
Calabi-Yau-alternate.png
Matter and mind differ only in degree not in kind.

Greater the vibration it is Mind; lesser , matter.

Based on various levels of vibration,there are 14 Levels of existence9Vishnu Purana).References are also available in Buddhism.

All thee  different levels co existed, co exist and shall co exist at the same in a cycle.

Please read my blog TIME.

 

 

Story:

String theory is a developing theory in particle physics that attempts to reconcile quantum mechanics and general relativity.[1] It is a candidate for the theory of everything (TOE), a manner of describing the known fundamental forces and matter in a mathematically complete system. The theory has yet to make quantitative experimental predictions, which a theory must do in order to be confirmed or falsified.

String theory mainly posits that the electrons and quarks within an atom are not 0-dimensional objects, but rather 1-dimensional oscillating lines (“strings”). The earliest string model, the bosonic string, incorporated only bosons, although this view developed to the superstring theory, which posits that a connection (a “supersymmetry“) exists between bosons and fermions. String theories also require the existence of several extra, unobservable, dimensions to the universe, in addition to the usual four spacetime dimensions.
