Particles and Waves

What is the difference between a particle and a wave?
Particles have identity. You can name a particle. It is like a person having a cristian name. Say there are identical twins, but each will have a different name, we treat each as a seprate person. You see the difference of a particle and a wave, only when you try to observe it. When you observer a particle you observe it all the way. When it moves you watch it's path continously. The wave you can't do it. In a wave you see the starting point and end point only. You can name a particle, since you observe it all the way in it's movement you know that it is the same thing that moves. What you had in position A is the same when it moves to position B. We watch it all the way. It is causal or localised not logical. But when a photon moves we cannot watch it all the way. We use logic to identify it as the same photon imited. We do it logically. We prevent any other photon to enter in to that space. Then we know what arrived is the one that was emited. It is like sending a ball in a opaque tube. We see the ball entering the tube, then we see the ball coming out of the tube. How do we know it is the same ball? logically. It is not causal. We know no other ball entered, so we know what came out is the same ball that entered the tube.

Understand this and it will solve lot of current problems in physics. The observer effect, "the moon is shining even when we don't look at it" - Einstein. Seeing the moon is logical. Seeing a table in front of me is causal. I touch the table on top of seeing it and get the feeling that it is real and not an illusion.

Identity of a particle in quantum physics

Philosophical Investigations-Wittgenstein, para 215. But isn't the same at least the same?
We seem to have an infallible paradigm of identity in the identity of a thing with itself. I feel like saying" here at any rate there can't be variety  of interpretations. If you are seeing a thing you are seeing identity too."
Then two things on the same when they are what one thing is? And how am I to apply what the one thing shews me the case of two things?

Take the case of single electron going threw two slits, how do we know it is the same electron the emitter emitted that strikes the detector? Our intuition, we emitted a single electron, we design the experiment so that outside electrons can't come in, like when you roll a marble in a opaque tube, you expect the same to come out. There's another way of doing it like watching the marble move through a transparent tube. Here you watch the marble move. The identity of the marble is fixed and not changing. There is a difference between the two methods.
In the first method identity is fixed, and in the second method the identity is vague, but we use our intuition to get the identity.

A particle behaves like a particle when the identity is fixed and it behaves like a wave when we use intuition to identity the particle.

When identity is fixed we know that the same particle moves. And in the other case, it is the negativity, like "this cannot be any other, therefore it is the same particle", we use logic to make the identification. The other case it is physical, you can touch and see the particle all the way.

In the second case an observer is present, whereas in the first case observer is absent.

Observer

In special relativity there is no traveling observer. They is only stationary observer. Traveling observer leads to twin paradox. Special relativity treats the twin paradox trivially. This is a mistake. Because of this mistake, all sorts of mythology has crept into science, or rather physics. It's like alchemy to chemistry. Time travel, many worlds theory etc. These leads to lot of contradictions. It may be good for fiction but not for science. What we need are good solid answers, these concepts are really flimsy. They are not practical no experiential proof is available.

Special Relativity treats both stationary observer and traveling observer as same. That they have same qualities, this is done without any proof. For instance first proof of special relativity mu-meson falling from the sky, it trys to treat that their is an observer in mu-meson, as well as the stationary observer sitting on earth. This is not practical, there is no clock that falls with mu-meson.

Special relativity treats as there are clocks everywhere, each point do space have a different clock and worse than that these clocks are all synchronised. Then the traveling observer also have a different set of clocks that travels with him, and each point in space has a different clock and they are all synchronised with the traveling observer. These assumptions are not practical, and don't have experimental proof, which results in twin paradox.

According to quantum theory when an observer is present things behave very differently. Photons when we observe behave like particles, when not behaves like waves. Special relativity is based on velocity of light, so, the same theory should be applied. Moving observer with a light clock, observing the stationary observer, will not see the same as the, stationary observer. One observer sees waves - with special relativity, other observer sees particles - without relativity. Therefore traveling clock will run slower to a stationary observer. But when the traveling clock also have an observer, either light behaves completely like a particle and light will not have constant velocity to both observers or to one of the observer (more study necessary to find out the circumstances) it behaves like a wave and particle to the other observer. Another important factor is it is known that doplar effect is seen in living light sources. This also should be taken into account.

This explanation can explain twin paradox.

Why world is not imaginary

Suppose there is a mountain and then there are people who sees the mountain. Each one who sees the mountain has a mental picture of the mountain in their brain. This can be represented by a set of data. Each one who sees the mountain will have a set of data. Mostly each of these data sets will be different. Further if one observer moves the set of data will change.

Then suppose that there is no mountain but only different data sets in the brains of each observer. When the observer moves the movement data is used in calculating a new data set continuously. All the data in these sets will be enormous.

Then consider the mountain is real and it's location, size and other details are given by a data set. Then also the location and movement of each observer is given by data sets. All this data will be a finite number.

When you consider the two options, imaginary mountain needs a large amount of data compared with the existence of a real mountain.

Therefore on the theory of minimizing data mountain should exist outside the imagination of the observer. Further it can be assumed that the world is real and not imaginary inside the observers brain.

Why Quantum theory instead of Classical Theory?
Using randomness uses less data than the Classical theory?
If so it will be proof why the world is Quantum.
If wave particle duality consumes less data than either waves or particles, that will be a good enough proof why duality exists.
If we can prove that if wave remains after observation need more data than becoming a particle that will be a good enough proof about the wave particle duality.

Human Brain and Quantum Theory

Lot of philosophers have said that God is the super mind. Each human being have a mind. All these minds are different. And at the same time all these minds have lot of similarities. If we create the super mind with all the good qualities of all of humans we get a super mind - this is one of the interpretation of God.

This human super mind has to be different that of a lion or any other animal. Lions vision is catered to find a pray. This shows that the makeup of a lions brain is very different of humans. The male lion kills the cubs not sired by him, then the mother of the cubs willingly cohabit with it's cub killer. This behavior is nonexistent in humans. So configuration of brains of lions and humans are very different. God of lions will be different from God of humans.

The world is perceived by our brains. When we define the qualities and attributes of the world around us, we assume that we can do a good job doing it independent of our brains. This is a mistake. It is evident from the discoveries of quantum theory and connected subjects of physics.

For instance 1+1 = 2 or A and B is true if and only if A is true and B is true, these are eternal truths according to our brain. What if we are wrong! What if these are just constructs of our brains. suppose someone has a gut feeling that 1+1 is not 2. Then we say that he is a lunatic. We have a group of people who has a gut feeling that 1+1 = 2. These are the normal people, these are the scientists and so on.

These normal people cannot comprehend how two distant particles can be entangled in such a way when qualities of one is derived the distant other half derives the opposite. When it is observed entities behave like particles and when unobserved behaves like waves.

The classical theories that can be comprehended by our brains cannot explain these pronominal.

If at some stage we can come up with a theory that could explain these effects then we can put in our basket of understanding our environment, what is happening. Sometimes it may not be possible. At the time when people considered the earth is flat not a globe they could not comprehend certain phenomena. They could not in the beginning understand that world is a globe even after someone explained it. In this way gradually people started believing earth is a globe. Now if someone say it is flat he will be considered as a lunatic

Similarly try to explain the properties of a torus to a two dimensional creature. If the torus is vertical and cut by a horizontal plane we get only two circles. Suppose the torus is horizontal the the circles will be one inside the other. If the torus is slanted the circles will not have the same center. This is what a two dimensional creature will see. In no way you will be able to explain to this two dimensional creature, what a torus is. But there is a certain tool where it can be done. It is mathematics! Using a algebraic equation of a torus, a two dimensional creature will be able to know it's properties. In this way using mathematics we have come to know most of the intricate details of our surroundings. But we can never be able to know all the details. When a new theory in physics is formed we come to know certain details. But we miss a lot.

Binary theory of space time

Heisenberg Uncertainty Principle is a derivation of a larger principal which says when information is available in a certain event the behavior of the participants are modified.

Traveling of a wave or particle can be seen as a transmission of information from one location to another. Even location can be considered as information, then traveling is change of information.

A particle is at a certain location at a certain time is information. This applies even to a wave. The difference is, a wave gives lesser amount of information.

We may be able to visualize the universe not as a system where waves and particles are located at a certain instant, but as a system of information only.

Waves and particles are a convenience given to us by our senses.

All information of the universe can be represented by a binary map meaning that all information of the universe in an instant can be given by a binary number. After any change in the next instant it can be shown by a different binary number.

Another thing change from one instant to another instant only one binary can change, multiple binaries cannot change. This may be treated as a definition at the moment, until it is proved why it has to be so.

Flow of time is a series of changes in the binary number. We do not need a different definition for time, outside this binary number, since we treat change of universe is a basic attribute and change of one binary as the basic change. The larger the binary number the smaller the change becomes. The size of the binary number is limited by the size of the universe. It should be noted that this binary number incorporates all particles of the universe as well as all waves, visible matter, dark matter and even dark energy.

This binary number is finite, at the moment it is accepted that the universe is finite, therefore it is compatible to treat this number as finite.

 Unfortunately this binary number will explain only the classical physics, quantum theory and uncertancy principal need modifications to zeros and ones. It may be necessary to be replaced by a probability function.

Further, to incorporate principal of causality, we need to connect in some way, or link two or more locations of zeros and ones.
