PHILOSOPHY



Introduction to the Subject

Philosophy is a subject of investigation on nature. Physics cannot be defined, but can be said as a study on the interrelationships of energy and matter.


ELECTROMAGNETIC THEORY OF LIGHT

By constructing an oscillating electrical circuit, electromagnetic waves could move through empty space. Light eventually was proved to be electromagnetic. Current light theory says that light is made up of very small packets of electromagnetic energy called PHOTONS (the smallest unit of radiant energy). These photons move at a constant speed in the medium through which they travel. Photons move at a faster speed through a vacuum than they do in the atmosphere, and at a slower speed through water than air. Light and similar forms of radiation are made up of moving electric and magnetic forces and move as waves. Electromagnetic waves move in a manner similar to the waves produced by the pebble dropped in the pool of water. The lines drawn from the light source (a light bulb in this instance) to any point on one of these waves indicate the direction in which the waves are moving.
Introduction to Sound


There are many examples of motion that do not involve life.
i.e.: Clouds, Wind.
The special 5th element other than the earth, water, air, water, and five in the heavenly body was known as “Ether” by Aristotle.

Basic reason behind the creation of a sound is to pass a message to others.
There is a proof that atoms can move. In optics from the Electro magnetic theory of light, it has been proved that electro magnetic waves and light are emitted when electric charges are in accelerated motion. This proves that atoms contain electric charges that can move.

Also, Atoms pushes the wave from one place to another.
Forced Motion


A stone thrown up in air goes up and falls down.

Why does it leave the hand because it is heavier than air and the force takes it upwards. The hand no longer has dry impulse. When it loses the force, it comes down.

The stone was carried in the air and air took it along. The impulse was transmitted from point to point.

This is a Forced Motion. This proves that sound waves are carried by heavier atoms or a wave heavier than the atoms in the air.
  


Movements
  
Movement of Atoms


The small “-” balls around the outside are electrons, the yellow “+” balls are protons, and the orange balls are neutrons


The approximate shape and charge distribution of water.



Movement of a single atom.


Oscillation and modulation of a wave

A Modulated Carrier Wave



Oscillation of a wave



A period of the main oscillation characterizes a pitch of a tone.


Sound

Breaking and piercing through a group of atoms, between the atoms, with same or two different kinds of particle atoms produces sound.

Kind of sound produced depends on the force (oscillation, modulation) you give to pierce the atoms and kind of materials (wave) used to pierce between the atoms.

It also depends on the kind of material used (i.e.: particles used in getting contact with each other. (Positive, Negative)).


What is a sound?

The concept or the method used to create a sound may be different like positive or negative.
But when two (kind) groups of particles merge to create a sound, as a result of the collision, a wave is generated on the surface of collision (atmosphere) on air. Thus a sound wave is generated.
Ex:    A stone thrown on water is also an example for this
(1 wave cycle = 1 group of cells)

A movement of a group of cells, with a level of modulation (at a particular level) (total 8 levels, 815 – types) with a fixed speed, is a sound.

(1 sound ? Air Horn)        (A sound through an equalizer)

A movement of two groups of cells, with same level of modulation,( and different levels of modulation – optional) with a fixed speed between 2 groups of cells has a sound (1 sound).

The probability of a cell from one group with all the cells from other group, with different levels of modulation, with a fixed speed between 2 cells from each group has different sounds. Ex: Drums, Alphabets.

                                                         
                     
Sound of a Thunder


How is a wave generated?
    A wave is generated when two sound particles bang and pierce
Atoms.

Note: Wave exists everywhere & has low power. What exists is a wave of low intensity. Imagine the intensity of a thunder sound. What happens when the sound with high intensity is spoken between 2 people..

      
                 
Creation of wave or group of cells

Imagine, throwing a stone on water, water is visible, a wave is generated on collision thus a group of cells are created on impact and they move in all direction around the surface.

This proves that a group of cells are generated.

Since we can see waves in water and cannot see waves in air, though waves in air can only be felt vibrations can be seen on impact.

Thus, different sounds are produced on an impact of two different kinds of atoms present in 2 groups of cells.

Example:    Stone (Group 1)    Water (Group 2)  
    Air horn (Group 1)
    Piano (Many Groups)
    +ve
    -ve
    Mixture



Reasons – Theory – Behind the creation of sound

Can a voice from a human reasoned.

A solution is there to know how a sound is generated. But is there a solution to know why that kind of sound is generated?

Human brain is powerful. It has a mixture of all kinds & sounds. +ve sounds, -ve sounds and mixture. A sound generated by a human brain cannot be reasoned or found.

When we say “A” why “A” is heard a sound and why not “B”. “A” comes but how does it come is the question. Ask any person who creates a particular sound to give reason for the sound he created. The source of the creation of sound can never be found. The source is nothing but the place where.

“A” can be heard. “A” travels as a wave fine. When A is said a group of atoms are created on impact of the sound and travels as a wave. This is where the kind of sounds +ve, -ve, mixture comes for help. If we know it we can find how that group of cells is formed together. This helps to separate different groups of cells into groups. Every piece of sound depends on the combination of a group of cells. Imagine the number of cells required to talk. Imagine the speed of the wave. Mind-boggling. There are proofs of huge numbers present in vedas. These numbers cannot be even computed by a computer. These numbers exist and keep working by in the form of combinations.

                                      
   
When particles hits an object, it pushes the atoms and hits the particle the heavenly  body present their creates waves because of pressure and force.
  
    It is a nuclear reaction converted to physical force. Ex. Bubbling of an acid is a reaction from chemical to heat.

    Here it’s atomic to wave. It travels in all directions. 360


Particle hit’s an object


Waves on Head


The Power of Sound


When a stone is dropped in water it generates waves. The weight of a stone forces the water which is of a lighter weight than stone to creates waves.

 Air has a special element or the heavenly body has a special element which converts a hit with a force as a wave.


The power of sound

    Since the wave hits the top of the head and travels through our body, if we know from where the sound is created we can find out and get connected to the supreme power.

    Finding out the reason for the creation of sound is like finding out what god is talking to us. If we find out the truth it’s like finding out, how the supreme power speaks. Sound is a creation of God. The power of sound exists by nature and man developed it till today.

    Until this is found the hearing impaired people cannot be cured.



Still – a solution exists:


    Mouth is linked to ears. There is one way for the hearing and speech impaired.
    Using the deaf and dumb language teach them the English language.
    Create a typing machine with a small screen.
    Teach them to type the keys.
    Make them communicate and live with the public as a normal person thus they become happy when they communicate and lead life as a average human.
    So, a machine with memory is a solution.
    SMS in cell phones, MMS, Pagers, Picture messages with vibrations.

CREATION
OF SOUND




Music on Computer


Sound Notes



Continuous Sound Wave

For every sound a wave is produced, for every continuous sound a continuous sound wave is produced.

A group of cells is for a wave, many group of cells is for a continuous wave.

Thus you can hear voice or music or a sound with a continuous sound wave.



How Different Sounds are Generated


            
Alphabets



How different sounds are generated?

When a kind of particles with a particular force. Pierces atoms upto a measured limit a kind of sound is generated.
Example: A

When a different kind of particles with a small variation in force pierces atoms upto a different measured limit a different kind of sound is generated.

Example: AAH

Note:    1. Different kinds of particles on contact produces different sounds.
    2. Variation of forces while piercing atoms produces variations in sound and volume.



Kinds of Sounds


Kinds of sounds

There are three kinds of basic sounds.
+ve sound
-ve sound
Mix sounds

    When two groups of same kind of particles bang each other, there generates a -ve sound.
    When two groups of opposite kind of particles bang each other, there generates a +ve sound.
    When a –ve and a +ve groups of particles bang, a mix sound is generated.

Let’s take a drum as an example for checking the kinds of sound generated.

A.    Positive sound

A stick is a product made of a wooden particle. The bottom of a drum has a space with air and atoms in it. The drum is covered with a skin particle.

When a stick bangs the skin of a drum it generates a sound by piercing the atoms within the drum. The skin is heavier than the stick particle.

This is a positive sound.


B.    Negative Sound

The plates on the drum which is heavier than the stick produces a –ve sound by banging with each other.
A heavier particle group (two), on banging with each other produces a more sound than a lighter particle.

So, it depends on a kind of particle for producing a sound.

Even, when a stick is used to beat the drum plates only the sound of the banging of plates sound gets generated from the plates.

This is a negative sound.

C. Mix Sound

The sound of the stick generated when a stick hit’s a drum is an example for a mix sound of +ve and –ve sound.

This is a mix sound.

Sound of a 2 Letter Word
            


Sound of two letter word

Example: BE

Imaging two groups of cells moving together to form a sound B. On collision a wave is created. A particular atom from two groups together on collision creates a cycle of a sound wave B.

Two move group of cells move together to form a sound E. on collision a wave is created. A particular atom from two groups together on collision creates a cycle of a sound wave E.

Sound Wave

Particular atoms from every group together on collision move together to create a wave called sound wave.

Why particular atoms:

A particular atom among a variety of atoms is called a particular modulation atom. There are many modulations. Every modulation has a sound.

A particular modulation atom with a different atom from a different group has a different sound.

Buzzer, calling bell is an example of fixed modulation.

Modulations generally occur one after other, after an interval of time.

i.e., Different atoms get modulated one after other to produce a continuous sound wave to generate sounds.


    Imagine a movement of group of cells, every group has many atoms. An atom from every group is selected on collision, a sound can be created.

    The probability of an atom, with other atoms from other groups is an example for many sounds.
    Always only particular kinds of atoms from different groups are selected to form a particular sound.

LIFE OF
SOUND

Life of a Sound

    Life of a sound physically is short and mentally long. Sound has life only until it travels. It can produce vibration on impact and can damage on heavy impact.

Ex. Ear drums

    Our brains can play with sound. Hearing and talking are examples of play.

    Thus sound generates life of a sound, through our brain. It stays in our brain that can be accessed. The memories of sounds are in the form of happiness, sorrows, fear, sentiments etc. As the sound wave loses its power, it gets diluted in air and gets destroyed.

Note:    The sound generated by humans cannot be judged as positive or negative because of a human brain.


Cell B:        Sound


The movement of a (different cells) (complex cells) at different levels of modulation with same speed at different intervals (A)…..(B) is a sound.


What is a hearing machine?

    A mike is a receiver. (cell A) ( ears)
    It is amplified by an amplifier. Amplifier is an equipment to multiply sound. (pressure and air)
    Modulation of volume and units of volumes is an equalizer. (cell B) (mouth and tongue)
    This is the reason why a wave machine or a nearing machine is used by a person with hearing and speech problems.

Digital hearing aid


What is a hearing machine?


A sound is created by an instrument
All the instruments designed, available and the music’s produced are based on the weight of a material, kind of material with an empty space of air containing atoms with different size, when given a force produces sound.

A sound by mouth of a human

A human voice is different from that of an instrument.

Air is forced in through nose, mouth and brought either inside stomach or chest and blown out from there through throat, where it is contracted.

Depending on the contract emerges a voice or a sound wave. This voice is controlled.

The sound produced here is controlled by the force of air blown through the throat into the mouth, modulated by tongue and out of the mouth breaking and piercing the atoms in front of our face.

                                           
Voice or Sound from Mouth

Computer Technology

The computer technology storages are based on bits 0’s & 1’s similar to the basics of atoms. Combination of these 2 bits of atoms is the formations of alphabets, words and sentences. So a whole of a language can be processed with a mixture of atoms 0’s & 1’s.

A problem still exists. A stored computer text can be copied, a stored music file can be played, a stored voice can be recorded and played and that is digital technology.

Have you heard of a secret where a typed in alphabets being processed for meanings and played as a song with a voice. A voice of a song can never be generated by a computer. A sound of a song can never be created on computer. It only can be stored and played.

An automatic global customer support voice is also not possible. The probabilities of the questions that may rise during the support are many.

Findings the meaning of a computer process is like finding out the complete meaning and behavior of the computer atoms, for every piece of sound.

If singing can be generated on a computer, then how a sound is generated can also be found. Since both have the same logic.

A voice with a modulation can be the maximum possible with computer but singing can never be possible that is sound. Sound has its own properties by nature which cannot be found.


Logical Life Cycle of a Sound by Talking

ETERNITY

Importance of a single atom, Power of Sound

If the atom of supreme power is so powerful to give us the power of life and make us think. Then it is important that we have to find out about it, get it and become blessed. But it’s not easy.

A lifetime is not enough for some but same learn and go through it with in a short time. The blessed life is different from a normal life. Enlightment occurs on blessing. Some may not get it at all even after trying for a long period. That’s the power of brain. The masters can take you there. There is no way of getting it without a master. Lucky ones feel the blessing. This is important since some humans even when blessed are not aware that they are blessed. That’s the pathetic of our brain.

At the same time the supreme power is so powerful that one atom can mingle in the air, with reactions can destroy the whole system. This is true.


A person who passed through that atom

This is the reason why some saints on being blessed are capable of playing dangerous plays. A saint has a power to give life to an innocent human. They can perform miracles with medicine or without medicine.

Saints can follow the voices of animals and retarded people. Retardation is curable by saints. Just imagine with what power they can cure ordinary diseases. Ayurveda is the best. Siddha is the best. This is the reason why they ask the people with incurable disease to take these medicines.

The life of a Saint goes beyond this world to the universe.

A person who does not pass through the atom

The human who doesn’t try to understand the supreme power suffers with pains and gets subtracted.


Eternity, Advanced Sounds

When a particular action is created (by mouth, or by thinking) a wave is created or a reaction takes place. That wave travels and hits the car of the other person and he gets a message.

A mantra is a message to the supreme power by human.

A human can think and convey a message. But he should know the secret of the atom to be sent. Since he does not know, he talks and conveys. Human brain also has the natural tendency to oppose the message. Some minds accept it without resistance. A speech by human by nature is opposed. An atom sent by thinking to humans by supreme power gets unopposed.

All the study towards eternity is for seeking the power of receiving the unopposed atom i.e. the message from the supreme power. When they are blessed that human gets the power to do an act by human easily. He starts to think more and reasons it. He finds the supreme power on every reason .The blessed finds the human talk in irrelevant this is the reason why a saint always talks and praises the power of supreme. If every human receives the blessing, there will be no human left who does not think, all humans will be good, no harms, and world will be a perfect place for humans to live world can be a heaven.

But what happened. Why it is worse till now? Why the wars? Why the fights? Why does god want us to fight? Is he playing with us? We humans ourselves have a huge brain power to get our self into control and without fight change this miserable would into a peaceful and calm world.

May be, he gave us such a huge brain to think and act and wants us to do it on our own. But who will bell the cat? How?

Will a human be born with a perfect knowledge and go to every person to teach him on good and bad. This seems not possible. Every person has to think on his own and be good. Get the blessings and start a pure life. When everybody does it a pure country will be born. When all countries become pure without violence and crime this world would have got rid of the –ve influences generated naturally by man.

Then the development will be automatic.

 God created a place to play with sound. The source of sound is generated by human mind only. The objects, materials, mouth; instruments are just the place where sounds are used to be produced.

Knowing the reason for the sound created by human mind
Must be the same as
Knowing the reason for the sound created by objects.

The formulas are think & play.

Mind is powerful
            Mouth, Instruments are less powerful.

    Also, they together act to form a sound.
Sound
    Group of atoms are created, processed and executed to form a sound.

INNOVATIONS

Lie indicator or Bluff Finder:-


There are 2 different kinds of attitudes; positive & negative. Positive attitude is godly. Negatively attitude is not good. Natural attitude or the positive thinking comes by nature. The artificial attitude or the negative thinking is developed by humans due to the external influences. Lie is one among them. You can never lie with a positive attitude. You can never speak truth with a negative attitude. Attitudes generate different kinds of waves from our body. Different reactions are made for different attitudes. The physical changes are visible. Reflections occur. This is the reason why god fearing people never lie. They can speak only the truth. Truth comes under the influence of the supreme power. Lie comes under the influence of human power. Human power has access to both truth and lie. The waves generated and the reactions for truth and lie are different . With a sensor we can check the reactions taking place in the body, while lying .Thus lying can be found. The sensor checks for the reactions for every answer being replaced for questions. This instrument is used while investigating the suspects.


Bluetooth with an inductor

An acoustic instrument

When we-ON-the blue tooth in our mobile we are able to hear what the other person speaks. And if we are really interested we can go and talk to him. The person is, the entire blue tooth, do not give a correct result. There is no fool proof technology for this till now.

But there is one solution. An advanced acoustic instrument of calculating the evection of a sound wave is the instrument on discussion. This is similar to a lie detector. This has to be connected between two people during the talk (cell) one sentence must be spoken at a time. The result whether the other person lies or speaks a truth can be found with an indicator (Red) (Green) (or) Beeps. This is an advanced future of blue tooth with this instrument you can either proceed your relationship or disconnect. This is an instrument to a world for peace. The lies and people who never lie can be identified.
To understand the indicator’s results, you should be clear with what questions you ask and what he replies.
Again it’s a complicated logic of brain.
When you ask a direct question – you can get a direct answer.
    The machine cannot think if you ask a twisted question – it can show you both right and wrong.
  
If you ask a negative question – it will give you a negative answer.
    So no logical reasoning can be done. Ask a simple question and reply must be a yes or a no. The answer can be confirmed to an indicator of red and green. T/F.

Suspect Locator

    Blue tooth alarm is another advanced acoustic instrument for the detection of criminals or abnormal humans who are in trouble.
  
This is for the officials who are on patrol. The alarm rings and shows you the path to the person with the beep of another instrument called (Global Route Locator). This is used in developed countries to locate a route to a destination. It shows the position where you are currently present. People with a high intension will have high – ve feeling. An alarm is an indicator which shows a man of high –ve feelings or high the feelings present around in an area. The local patrol can reach them when this alarm a blue tooth lie detector is connected to (Global route location). It takes the patrol team to the exact position of the criminal. General humans will not be effected by it u can call it –  SL-suspect locator.



Digital Logic Suspect Locator
  
It is similar to the computer technology bit’s 0 + 1.
    A letter can be formed with 8 bits .So 8 questions have to be asked to know an answer. A word can be formed with a group of letters. So that many questions has to be asked. A sentence has to be formed.
    Now imagine the number of questions that has to be asked on investigation to know the truth.
This is a formula for investigation. Each letter must have its own characteristics, test, reasons, anger, hatred, violent, harmless.
Agatha christhie is a master in it.  
This method is a simple tool on simple purposes and acts as a powerful tool for powerful purposes. Since a logic cannot be recorded in an instrument. The digital technology helps us to form a command and create logic and gives us a result. In the case a culprit or a truth. Among the results,
                        A letter is assumed a variable.
The word as a constant.
                            The questions are the conditions.
            The result is a loop.
            The result is an answer.

    This is the maximum possible assumption on the creation of sound with the beep of a machine and brain. This is also acoustic equipment on the creation of sound.
    You can find the truth with logical resolving but you can never find an explanation of the truth. You can only assume it. You can also, not find the history behind the truth. It has to be found only by assumed investigation. Thus an assumption is important and gets you very close to the result. Humans can mislead but can be caught easily.
  
This is nothing but on SQL on a database. You get an exact idea with the results from your SQL questions.
  
A computer may mislead with a wrong-logic. There’s no wrong – logic with an artificial intelligence. It gives you an idea with a result.
  
This instrument will not work well with retarded and supreme power. But will works well otherwise.

FUTURE OF
SOUND


Future of sound

Sound is good to us when we use it in a good manner. It is hazardous to us when not used in a good manner. Since the numbers of sound that can be generated are uncountable we have to start thinking to use it efficiently. There are a lot of possibilities to create new musical instruments. More musical sounds can be generated.

The music which exists how must be only 1 billionth of the musical sounds that can be generated. Caution has to be taken on negative attitude of talking since it affects the brain. The awareness of pleasant sounds must be spread. A lot of music is yet to be explored. Nature is always there for support.



Conclusion

A study on the behavior of atoms and their properties are required to study the creation of sound. However using computers logic we can find the source of a given problem.

On the way to find the creation of sound, a lot of other small details related to sound came to get accessed. These are present in this manual.

A Bluetooth with an indicator is an instrument of future, just predicting. Its fun to use, it’s entertaining at the same time useful.

DADMES is an instrument that can be easily designed and manufactured. Just imagine the hearing impaired peoples feel when they start communicating with an instrument of vibration. They sure will be happy. And it doesn’t cost much with our current technology and facilities available today.



REFERENCE

FOR REFERENCE FROM BOOKS


Sound Waves

A book says “In the case of elastic waves the disturbance travels with a velocity depending upon the elastic properties of the medium”. These elastic waves are also called sound waves.

Wave Motion Occurs due to repeated periodic motion of the particles of the medium, about their mean position, the disturbance being handled over from one particle to next.

In a wave motion matter is not propagated but different. It is a dynamic condition.


Frequency of a wave

Refers to how often the particles of the medium vibrate when a wave passes through the medium.

1 Hertz = 1 Vibration / Second

As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. Each particle vibrates due to its nearest neighbor.


Pitch

It’s the sensation of frequencies. The amount of energy which is transferred to the medium depends on the amplitude of vibrations of a (guitar) string.


Intensity

Intensity =     Power        or        Energy        
        Area                Time X Area

The amount of energy transported through a given area of the medium per unit of time is known as the intensity of a sound wave.


Amplitude

The vertical distance from a node to either a crest or a trough is the amplitude of a wave.


Boyle

Boyle studied air and found it can be compressed or expanded like a sponge.


Lissajous figures

States, when a particle is influenced simultaneously by two simple harmonic motions at right angles to each other, the resultant motion of the particle traces a curve. These curves are called as a Lissajous Figure.


Example of waves :

X-Ray, Radio waves.

Tips:

    16 hertz – 20,000 hertz    -    Ear
    > 20,000 hertz            -    Ultrasonic waves


Table

    Source    Intensity Level
    Whisper             20 db
    Normal Conversation    60 db
    Vacuum Cleaner      80 db
    Threshold of Pain    130 db

Newton’s Formula for velocity of sound

The velocity of a sound in a medium, solid, liquid or gas depends on the elasticity and density of the medium.


Velocity

A wave travels with a uniform velocity, but velocity of the particles is different at different positions. It is max at the object where sound is raised, i.e. mean position and 0 at the extreme position.

Velocity of the wave is the distance traveled by the wave in one second.

Velocity    =    Distance /  Time


Forced Vibration

The time taken by a body executing a harmonic motion depends on the dimensions of the body and its elastic properties. These vibrations die out with time due to dissipation of energy.

If some external periodic force is applied on the body, the body continues to oscillate under the influence of such external forces. Such vibrations are called forced vibrations.

Free Damped Vibrations

Energy is dissipated in the vibration and oscillation does out.


Decibel

Abbreviated – db
It is dimensionless, since it refers to the ratio of 2 similar quantities.

Resonance:    The oscillations will have maximum amplitude such a vibration is called resonance.


Doppler Effect:    A change in pitch between the source and observer is called Doppler Effect.

Tip:    It is heavily impossible to create an instrument which can show the flow of a sound wave.

Tip:     All particles have some amplitude, frequency and time period.


Acoustics

The branch of physics that deals with generation, reception and propagation of sound is called acoustics.








ANY QUESTIONS

Do  not ask any questions on these topics since all of these are based on common reasoning’s, general & scientific assumptions and also I am not fully informed on physics especially nuclear physics. I’ll inform you further with new topics when I get to know the behavior of atoms better.

Until then all I can say, when you raise a question or I myself raise a question is “I don’t know, Please check with an Acoustics man”.
