Introduction: Knowing the velocity of an object by Newton's law of motion, it is possible to
accurately measure the position of the object after time t. That idea was rejected in the quantum
world after Heisenberg's discovery of the principle of uncertainty. Since the discovery of the
uncertainty principle, we all know that it is not possible to measure the position and momentum
of a particle at the same time. But the method of measuring the position and momentum of a
particle simultaneously is hidden in the principle of uncertainty. In 1927, Heisenberg invented
the principle of uncertainty. The essence of this principle is that "it is not possible to accurately
measure the position and momentum of a particle at the same time". The more accurately you
know the position, the more uncertain the momentum will be. Again, the more accurate the
momentum is, the more uncertain the position will be. had been opposed to the principle of
uncertainty since its inception. He was in conflict with Nils Bohr until his death. Einstein would
say that surely God does not play dice. Many think Einstein was wrong then. But surprisingly,
Einstein and Heisenberg were both right. I have previously published a research paper on
quantum certainty mechanics for the relationship between the principle of certainty and the
principle of uncertainty. This research paper deals with the method of determining the position
and momentum of a particle simultaneously from the principle of uncertainty. The position will
be uncertain if the momentum is measured accurately according to the uncertainty principle.
Again, if the position is measured with certainty, the momentum will be uncertain. The value of
any one of the principles of uncertainty must be uncertain. we take the momentum-position as a
packet and multiply an additional k indefinite value, we will be able to determine the position
and momentum of the particle.
Method: Suppose we have two numbers p and q. We do not know the exact value of p and q but
we assume that the value of p and q is 10 or greater than 10.The higher the value of p and q, the
more accurate p and q will be but there is no set value. To say more value can be infinite value
But then there will be problems. So we assume for the convenience of calculation that if the
value of p and q is close to 10 then it will be close to the correct value. Now we are given an
equation. That is the product of p and q is 10 i.e. pq = 10.From this equation, if we get closer to
the correct value of p, we will move away from the correct value of q. Again, if we get close to
the correct value of q, we will move away from the correct value of p. That is, if you know one
value, the value of the other will be wrong. The value of the product of p and q can be 10 in
many ways,
pq = 0
10×1=10
or , 5×2 =10
or ,1×10=10
or , 2×5=10
Our equation is,
pq = 10
From this equation we will never get the value of p=10 and the value of q=10 at the same time.
But if we multiply an additional constant by pq then the values of p and q will be 10 at the same
time. Suppose the correct value of p is 10 and the correct value of q is 10.Then pqk = 10
according to the above equation . That is, if p = 10, q = 10 then k = 1/10.Now if the exact value
of p and q is close to 10 then the value of k will go towards uncertainty. If we consider p and q as
a fixed value then the value of k will be uncertain. According to the above equation, the product
of two packets should be 10, where pq is a packet of fixed value and the remaining indefinite
value k is another packet.
(pq)k 10
In this way we will express Heisenberg's principle of uncertainty. According to uncertainty the
values of momentum p and position x can never be measured with certainty at the same time. If
the momentum is confirmed the position will become uncertain. The indefinite product of the
two states will be equal to or greater than the Planck constant that is ∆p∆x = . Now, according
to the uncertainty principle, even if one has a value, one has to be uncertain. Now suppose by
any means we know ∆p and ∆x for sure. Whether by observing it or in some other way. Suppose
we were able to invent an instrument that could accurately measure the position (∆x) and
momentum (∆p) of a particle. Then an additional constant k has to be multiplied to protect the
uncertainty principle. k is an ongoing uncertainty value that has been used to protect the
uncertainty principle. If ∆x∆p is confirmed then the constant k will be an uncertain value. Then
we can write the equation,
∆p∆xk= ℏ (24)
k is an unknown constant. If k = 1 then the uncertainty formula will be ∆x∆p = .The definite
value of momentum and position has been taken as a packet.
Then the equation will be,
(∆x∆p) × k = ℏ.
One packet is of momentum-position and the other packet is of constant k.
Now if k is confirmed (∆x∆p) will be uncertain. That is , if k = 1 is confirmed (∆∆p) will be
uncertain. Again , if (∆x∆p) is confirmed , k will be uncertain. Now suppose, we are sure
(∆x∆p) then the value of k is uncertain according to uncertainty.
From (∆x∆p)×k= the uncertainty of energy and time will be:-
We know kinetic energy E=1
2mv2 .
Now We get by Taking the first derivative of the total E (i. e. kinetic energy) with respect p,
∆E= 𝑝
𝑚∆p
∆E=v∆p (25)
We get from Equation 25 and Equation 24,
∆E∆xk=vℏ
=>(∆E∆t)k=ℏ (26)
From the above equation 26 we can see that imagining energy-time (E∆t) as a fixed packet will
make the k constant uncertain.
Equation 24 is divided by Equation 25.
(xp)×k =
(Et)k = (27)
In equation 27 (∆x∆p) and (∆E∆t) are definite values . so we can write,
(xp )×k=
(Et )k= (28)
Since Equation 28 comes from Equation 24, the value of ∆k is the same in both cases.
So we can write,
xp = Et
Therefore,
xp = hft (29)
Equation 29 is the principle of certainty which comes from the principle of uncertainty.
From equation 29 position (x), momentum (p), time (t), frequency (f) are the definite values.
Thus, knowing the momentum and frequency, the position can be determined after (t) time. The
more accurately the momentum can be measured, the more certain the position will be.
Decision: xp= hft is the principle of certainty by which after knowing the frequency of the waves
involved in the electron if we know the momentum we will be able to know the position , and if
we know the position we will be able to know the momentum . When we go to see the particle
in the laboratory and hit it with a photon, the particle receives hf amount of energy. If we ignore
that, we will not be able to know the position and momentum of the particle at the same time.
Electrons are particles like a marble(toy) and photons are also particles like a marble(toy).If you
hit the marble with the marble, the speed-position is known by calculating the strength of the hit.
Similarly, when looking at an electron in a laboratory, it is important to bring in the hf amount of
energy in the calculation due to the F force of the photon .In the above equation hf amount of
energy is brought And the momentum-position of the particle can be known simultaneously after
the t time from the equation. xp=hft; this equation is established by maintaining the condition of
uncertainty from the principle of uncertainty.
Conclusion : The principle of uncertainty is an important formula of quantum mechanics.
The uncertainty principle is 100% accurate but the momentum and position of the particle can
be known with certainty using some conditions in the uncertainty principle. If we know the
momentum and the absorbed energy by the particles in the laboratory, we will be able to
determine the exact position of the particles after time t .From the principle of uncertainty, we
add an additional k constant to the momentum-position uncertainty and energy-time uncertainty
of the particle. Then the position and momentum of the particle can be measured at the same
time from that equation. And this is the principle of certainty. There is a relationship between
uncertainty principle and certainty principle. The principle of uncertainty and the principle of
certainty complement each other. I have previously published a quantum certainty mechanics
research paper where the principle of uncertainty can be proved from the principle of certainty.

Quantum certainty mechanics is a theory for measuring the position and momentum of a particle. Mathematically proven certainty principle from uncertainty principle, which is basically one of the most important formulas of quantum certainty mechanics theory. The principle of uncertainty can be proved by the principle of certainty and why uncertainty comes can also be proved. The principle of certainty can be proved from the theory of relativity and in the uncertainty principle equation, the principle of certainty can be proved by fulfilling the conditions of the principle of uncertainty by multiplying the uncertain constant with the certain values of momentum-position and energy-time. The principle of certainty proves that the calculation of θ ≥π/2 between the particle and the wave involved in the particle leads to uncertainty. But calculating with θ=0 does not bring uncertainty. Again, if the total energy E of the particle is measured accurately in the laboratory, the momentum and position can be measured with certainty. Quantum certainty mechanics has been established by combining Newtonian mechanics, relativity theory and quantum mechanics. Quantum entanglement can be explained by protecting the conservation law of energy.

Heisenberg's uncertainty principle is usually taken to express a limitation of operational possibilities imposed by quantum mechanics. Here we demonstrate that the full content of this principle also includes its positive role as a condition ensuring that mutually exclusive experimental options can be reconciled if an appropriate trade-off is accepted. The uncertainty principle is shown to appear in three manifestations, in the form of uncertainty relations: for the widths of the position and momentum distributions in any quantum state; for the inaccuracies of any joint measurement of these quantities; and for the inaccuracy of a measurement of one of the quantities and the ensuing disturbance in the distribution of the other quantity. Whilst conceptually distinct, these three kinds of uncertainty relations are shown to be closely related formally. Finally, we survey models and experimental implementations of joint measurements of position and momentum and comment briefly on the status of experimental tests of the uncertainty principle.

Heisenberg's uncertainty principle has been understood to set a limitation on measurements, whereas the long standing mathematical formulation does not allow such an interpretation. Recently, a new relation was found by the present author to give a universally valid relation between noise and disturbance in general quantum measurements, and it has become clear that the new relation plays a role of the first principle to derive various quantum limits on measurement and information processing. Here, we discuss the state-dependent notion of precise measurements of a given observable, and consider a perfect distance such that zero distance implies the perfect correlation. Then, we shall show that even in the perfect error notions both the position measuring noise and the momentum disturbance can be arbitrarily small. We also show that it is possible to generalize the new noise-disturbance uncertainty relation to perfect error distances.

In der vorliegenden Arbeit werden zunchst exakte Definitionen der Worte: Ort, Geschwindigkeit, Energie usw. (z. B. des Elektrons) aufgestellt, die auch in der Quantenmechanik Gltigkeit behalten, und es wird gezeigt, da kanonisch konjugierte Gren simultan nur mit einer charakteristischen Ungenauigkeit bestimmt werden knnen ( 1). Diese Ungenauigkeit ist der eigentliche Grund fr das Auftreten statistischer Zusammenhnge in der Quantenmechanik. Ihre mathematische Formulierung gelingt mittels der Dirac-Jordanschen Theorie ( 2). Von den so gewonnenen Grundstzen ausgehend wird gezeigt, wie die makroskopischen Vorgnge aus der Quantenmechanik heraus verstanden werden knnen ( 3). Zur Erluterung der Theorie werden einige besondere Gedankenexperimente diskutiert ( 4).

A coherent account of the connections and contrasts between the principles of complementarity and uncertainty is developed starting from a survey of the various formalizations of these principles. The conceptual analysis is illustrated by means of a set of experimental schemes based on Mach–Zehnder interferometry. In particular, path detection via entanglement with a probe system and (quantitative) quantum erasure are exhibited to constitute instances of joint unsharp measurements of complementary pairs of physical quantities, path and interference observables. The analysis uses the representation of observables as positive-operator-valued measures (POVMs). The reconciliation of complementary experimental options in the sense of simultaneous unsharp preparations and measurements is expressed in terms of uncertainty relations of different kinds. The feature of complementarity, manifest in the present examples in the mutual exclusivity of path detection and interference observation, is recovered as a limit case from the appropriate uncertainty relation. It is noted that the complementarity and uncertainty principles are neither completely logically independent nor logical consequences of one another. Since entanglement is an instance of the uncertainty of quantum properties (of compound systems), it is moot to play out uncertainty and entanglement against each other as possible mechanisms enforcing complementarity.

First, exact definitions are supplied for the terms: position, velocity, energy, etc. (of the electron, for instance), such that they are valid also in quantum mechanics. Canonically conjugated variables are determined simultaneously only with a characteristic uncertainty. This uncertainty is the intrinsic reason for the occurrence of statistical relations in quantum mechanics. Mathematical formulation is made possible by the Dirac-Jordan theory. Beginning from the basic principles thus obtained, macroscopic processes are understood from the viewpoint of quantum mechanics. Several imaginary experiments are discussed to elucidate the theory.
