Intrinsic Spin Angular Momentum of Electron Relation to the Discrete Indivisible Quantum of Time Kshana or Moment ()
1. Introduction
Time is a parameter used to describe the dynamics. The frequency of any periodic event can be defined in time units. A unit of time can be constructed using other physical constants [1].
Planck constructed a unit of time called Plank time from other physical constant which is
sec where, c, G, and
are the speed of light, Newton’s constant, and Planck’s constant respectively [2]. The Planck time is the time taken by the speed of light to travel the Planck length, and the Planck length is the reduced Compton wavelength of the Planck mass. Planck length is the minimum indivisible length interval [3]. Planck Time offers little or no ontological meaning (relating to the branch of metaphysics dealing with the nature of being) to concepts of time, leaving many questions about its usefulness [4]. Determining this time scale is far beyond that of currently available technologies [2].
Heisenberg proposed existence of a fundamental length, λ, and therefore of a fundamental time chronon
[5] [6]. The concept of a quantized unit of interval or space-time s0, introduced by A. Charlesby, relates to the rest mass m0 of a particle as
. Time and distance between events were also quantized into units
and
respectively [7].
According to the old civilization of India, time is a discrete quantity, constituted of indivisible “present moments” [6] [8]. Maharishi Vyasa defined the quantum of time “kshana” or “moment” which, according to him, is the time taken by an elementary particle to change its direction from East to North. This is the smallest part of time, like an indivisible fundamental particle. Continuous flow of “kshana” one after the other is “krama” or “succession”. Combined with the help of intellect, “Moment” and “succession” appear to us as continuous entities like day and night. “Kshana” and “succession” are nothing but creation of mind. Ordinary people cannot differentiate between “kshana” and “succession” due to their inability to concentrate on “Moment” and “succession”. To them, both appear to be the same just like “word” and its “referent” [8] [9].
Although not composed of matter or having no material existence, “kshana” is dependent on succession. This phenomenon of succession is referred as “Time”. Two “kshana” at a time do not coexist and by succession also they are different, because it is not possible. The succession of “kshana” is nothing but the absence of gap between the earlier and the next “kshana”. The present itself is a “kshana”. Therefore, there is nothing like the past and future “kshana” or moment. For the same reason, they are not identical. Due to this present “kshana” or “moment” one can see changes in the universe. Every effect in this universe is the outcome of the present “kshana”. Therefore, each attribute is dependent on the present “moment”. It will be clearly visible if we concentrate on “moment” and its “succession” [8] [9].
The spinning electron model based on Maharishi Vyasa’s definition of kshana is successful in explaining most of the properties of the electron such as radius, spin angular momentum, spin magnetic moment, and rest mass. Based on the Maharishi Vyasa’s interpretation of kshana as explained above, Wanjerkhede, S. (2022), in case of pair production, found the value of a kshana which is approximately equal to 2 × 10−21 sec, and the radius of the spinning electron or positron is equal to the reduced Compton wavelength [10]. During validation, we also found that, in case of the photoelectric effect, spectral series of hydrogen atoms, Compton scattering, and the statistical concept of motion of electron, the value of the number of kshanas in a second and the value of a kshana is the same as that found in pair production [10].
Spin, a quantum mechanical concept has an intrinsic form of angular momentum carried by elementary particles such as an electron. Butto N. (2021) explain the spin of the electron at the sub-particle level, based on the vortex model of the electron. The electron is described as a superfluid frictionless vortex which has a mass, angular momentum, and spin, and provide a complete explanation of all properties of the electron spinning around its own axis. The direction of the angular momentum of a spinning electron vortex is along the axis of rotation and determined by the direction of spin [11].
2. Methods
Based on the definition of kshana (as defined by Maharishi Vyasa), the number of kshana “n” in a second, the value of a kshana in seconds, and the radius of the fundamental particle, such as an electron, can be determined, as shown here. According to the definition of quantum of time “kshana”, which is the time taken by the indivisible fundamental particle to change its direction from east to north is shown in Figure 1 [8] [11]. Let rs be the radius of the spinning electron in meters and Ts is the period of spin in seconds. If v is the spinning relativistic velocity of an electron, then:
(1)
According to Vyasa’s definition of kshana, the period of the spinning electron is
kshana. Therefore, the velocity of the spinning electron c' m/kshana, is:
(2)
The number of kshanas per second is
kshana/sec. By substituting the values of the velocities of light c and c' from Equations (1) and (2) into the Equation (3) for n, we obtain,
(3)
and
(4)
and
(5)
For a Compton radius of electron which is equal to Reduced Compton wavelength (
), and
[12] is
[13] [14] [15]. From Equation (3), the number of kshana n is 4.942359849 × 1020 kshana, and a kshana is 2.0233249508 × 10−21 sec.
Figure 1. A simple thin circular plate model of spinning electron. Z-axis is the axis of rotation in the anticlockwise direction. Ts is the period of spinning electrons in sec. When the direction changed from east to north,
is equal to 4 kshanas. The relativistic spinning velocity of an electron v is equal to the velocity of light, c. w' rad per kshana is the angular velocity.
In the following subsections, we determine and verify the number of kshanas in one second and the value of one kshana in second using different electron models.
2.1. Intrinsic Spin Angular Momentum of an Electron and Value of a Kshana
An electron has an internal angular momentum, called spin, which contributes to its total angular momentum [16]. The electron spin angular momentum is
. The allowed values of s are 0, 1/2, 1, 3/2, so on. For an electron
and the magnitude of its spin angular momentum vector is
[11]. The z-component has two possible values
[16] [17].
2.1.1. Angular Momentum of a Simple Thin Circular Plate Model and Intrinsic Spin Angular Moment of Electron
The moment of inertia of a thin disk of mass M and radius R about an axis
through the centre and perpendicular to the thin disk is
[18]. The angular momentum of the thin disc is
(Figure 1), where w is the angular velocity of the thin disc [18].
We assume that the electron has a thin, disk-like structure, as shown in Figure 1. Let its intrinsic spin angular momentum
, is equal to its angular momentum
, where
and
is the spin angular velocity of the electron [16] [17] [19]. Thus, the intrinsic angular momentum [20]:
(6)
where the mass electron at rest is m0 and its radius is
. Rewriting the above equation when the time unit is kshana, we obtain,
(7)
where,
J.kshana and
rad/kshana and n is the number of kshana in a second. Thus,
(8)
But, from Equation (2),
. Therefore,
(9)
Since velocity of light
m/kshana, and
MeV, therefore, we have,
(10)
(11)
Thus, the number of kshanas per second is 4.94237 × 1020, and the value of one kshana, is, 2.02332079 × 10−21 s. The spinning period of electron Ts = 4 × 2.02332079 × 10−21 = 8.09328316 × 10−21 sec. The results obtained for the number of kshana in a second n, and the value of a kshana in a second are the same as those obtained from Equation (3) and in an article published by Wanjerkhede S. M. [10] [21].
Table 1 shows the value of number of kshana “n”, and the value of a kshana in second for various methods adopted to find them. Equation in the first row is derived based on Maharishi Vyasa’s definition of kshana which is very generic in nature. Value of “n” depends on the radius of the circular orbit. May be a radius of the spinning electron or any other spinning fundamental particle radius or Bohr radius of the first orbit of hydrogen atom [9]. The value of “n” in the second row is when we considered the ratio of spin and orbital periods of hydrogen atom.
Again, re-writing Equation (10) using the mass-energy equivalence relation
, where
is the threshold frequency of gamma radiation [20] [22]-[25], we obtain,
(12)
(13)
(14)
where,
and
are the period of gamma radiation and the spinning period of an electron, respectively. Equation (14) shows that when the gamma radiation disappears, an electron is produced which has the same spinning period [10].
Here, it is worth to note that there is connection between the gamma ray and electron spin. According to Ohanian, H. C., “the spin of the electron may be regarded as an angular momentum generated by a circulating flow of energy in the wave field of the electron [26]” and for Richard Gauthier “The electron is a charged photon” [27].

2.1.2. Angular Momentum of a Spherical Shell and Total Spin Angular Momentum
The electron has finite spin angular momentum of
[16] and this spin angular momentum is equal to
[17] [28], where, I is the moment of inertia of the electron and is equal to
, whose rest mass is
and revolve around the centre with radius
(Figure 2).
Equating the total spin angular momentum to the angular momentum of the spherical shell yields,
(15)
The above equation is expressed in time unit kshana, as shown in Figure 2. We get,
(16)
Substituting for
,
, and
from Equation (5), we have
(17)
Now, number of kshana n in a second will be,
(18)
Thus, the number of kshanas in a second

2.1.3. Angular Momentum of a Spherical Shell and z-Component of Spin Angular Momentum
The z-component of spin angular momentum of an electron is
. The relationship between velocity v and angular momentum for a spherical shell of mass m0 and radius
was
[28]. For a spherical shell, the moment of inertia is
[16] [17]. By equating the angular momentum of a spherical shell and the z-component of the spin angular momentum, we obtain:
(19)
Re-writing Equation (19) when time is in kshana, we have:
(20)
Substituting for
,
, and
, we get,
(21)
Thus, the number of kshanas in the second
kshana and
. The average value of Equations (18) and (21) for the number of kshanas in a second is
kshana which is the same as that shown in Equation (11) and is in good agreement with the values found in a previously published article [10].
2.1.4. The Angular Momentum of a Solid Sphere and the Total Spin Angular Moment
Following Figure 3 shows the solid sphere spinning around the z-axis.
Figure 3. Solid spherical model of a spinning electron.
Again, let the spin angular momentum
be equal to the angular momentum
, where the angular frequency is
rad/sec, and the moment of inertia is
. Therefore,
(22)
Now, substituting the value of
from Equation (3) in Equation (22) in which the angular frequency w rad/sec is w' rad/kshana, and the Planck constant h J.sec is h' J.kshana, we have,
(23)
(24)
where,
sec/kshana. Solving the above for n, we have,
(25)
(26)
Thus, the number of kshanas in a second
kshana, and
.
2.1.5. Equating the Angular Momentum of a Solid Sphere with the z-Component of the Spin Angular Moment
The Z-component of the spin angular moment is
, and the resulting equation for n is:
(27)
(28)
Thus, the number of kshanas in a second
kshana and the value of a kshana is
. The average value of n is equal to 3.11833304985 × 1020 which is much lower than the results obtained previously, where the number of kshana
kshana, and a kshana is 2.0233249508 × 10−21 sec (as shown in Equation (3)) [10].
3. Results
3.1. Validation of Kshana
Validation of kshana in seconds is described in the following subsections.
3.1.1. Classical Electron Model of Spin, Kshana and Reduced Compton Wavelength
The spin angular frequency of the electron, in a semi-classical model, is related to its rest energy by
and the relativistic velocity
, where
is the angular frequency (and c is the velocity of light with which it is spinning) of the spinning electron with a mass of
[19] [29]. Thus, the radius of the electron is:
(29)
where,
denotes the reduced Compton wavelength. For the simple thin circular plate model of Zhao (2017), the electron radius being
, and the spin angular momentum [19] are
(30)
(31)
When time is in kshana,
and
, where
(see Equations (3) and (11)) is the number of kshana in a second, then we have,
(32)
(33)
(34)
(35)
Substituting the values of
,
, and
we have,
(36)
(37)
The radius of the electron is equal to the reduced Compton wavelength, which confirms the accuracy of the kshana.
3.1.2. Electron-Positron Pair Generation and Kshana
In electron-positron pair generation, the threshold energy of the gamma radiation required is 1.022 MeV and for electron generation the gamma ray energy is 0.511 MeV [30] [31]. The frequency of gamma radiation is,
(38)
where
is Planck constant. The period
sec and wavelength
are,
(39)
If
is the radius of the spinning electron, the relativistic spinning velocity of the electron is
m per kshana. According to Vyasa’s definition of kshana-, (Figure 1), is given by the following equation:
(40)
where, the electron spinning period is
kshana. However,
, assuming that the period of gamma radiation is equal to the spinning period of the electron that is,
(Equation (14)). The attribute of the cause was found to be present in the effect [10] [32]. Therefore, in this study, it is assumed that the period (an attribute) of the spinning electron or positron (effect) is the same as that of the photon (cause) [10] [32]. From the above equation, we obtain the following:
(41)
Thus, the circumference
, and the radius of the electron is
[10]. Keeping the value of
of Equation (39) in Equation (41), we obtain:
(42)
This indicates that the radius
of the spinning electron is consistent with the Compton radius [13]. Now, if n is the number of kshanas in a second, then from the above equation, we obtain:
(43)
Therefore,
. Again, this shows that the value of the number of kshana n in a second and the value of a kshana in seconds are in good agreement with the values previously determined in the article [10].
3.1.3. Superfluid Frictionless Vortex Model of Electron and Quantum Time Kshana
Electron spin is the particles’ intrinsic angular momentum S given by the equation
(44)
where,
, and n is any non-negative integer [11]. In hydrodynamics, the magnitude of the angular momentum of the vortex L is proportional to moment of inertia I and angular speed
radians per second. Therefore,
(45)
The angular momentum of the vortex L is the angular momentum relative to the centre. For a single particle
and
for circular motion [11]. Now, angular momentum is:
(46)
where
is the radius of the vortex, and m0 is the electron rest mass. Equating above Equation (46) to
, for
, we have,
(47)
When time unit is kshana, we have,
(48)
Substituting the relativistic spinning velocity
meter/kshana in the above Equation (48), we get,
(49)
Since
(50)
(51)
Alternatively, we find
as shown below: The velocity of the fluid element instantaneously passing through a given point in space in the vortex with radius
is constant in time; therefore, the circulation or the vorticity
is constant, where c is the speed of light. For electron mass
, conserved momentum is
. Therefore,
is constant, which equal to the Planck constant [11]. Thus,
(52)
Rewriting the above Equation (52) when time unit is kshana, we have,
(53)
From Equation (2), where c' is the relativistic spinning velocity.
(54)
Substituting this relativistic spinning velocity in the above Equation (54), we get
(55)
(56)
Now, the value of number of kshana in a second is:
(57)
Thus, the value of n is same as previously found by Wanjerkhede S. M. as shown in Table 1 [10] [21].
4. Discussion
The quantum time unit kshana or moment is much more human-oriented, meaningful, constant, discrete, exceedingly small, cannot be further divided, and is independent of external perturbations as compared with the time unit second. For ordinary people, the time appears to be smooth and continuous, similar to “day and night”. However, time does not flow continuously. This is neither smooth nor continuous. According to Vyasa, the quantum of time is discrete [9]. The value of a “kshana” found is of the order of 10−21 sec which is still large as compared with quantum time chronon (6.266 × 20−24 sec) [6] [33] and Planck
time (
sec) [34].
When kshana is compared to Compton time, Compton time is larger than the kshana. The Compton time is the time for a photon to travel the Compton wavelength. Mathematically it is
sec. Where,
is Compton time,
is Compton wavelength, c is the speed of light. The reduced Compton time
is
[35]. The Compton time
is related with quantum time kshana as shown here,
(58)
where,
,
,
, and quantum time kshana
(Equations (2), (3), (4), and (29)). However, quantum time kshana is very large as compared to the reduced Compton time for the critical Friedmann mass in the Hubble sphere which is 1.26 × 10−104 sec [35].
Kshana is dependent on the radius of the electron (Equation (3)), it can take any smaller value, even smaller than the Planck time [9]. For example, for radius of graviton
, the value of kshana is
[9] [36]. Thus, quantum time “kshana” based on spinning period of electron, is a natural unit of time.
We calculated the value of kshana with different models of spinning electrons as discussed above and found that a simple thin circular plate model along the z—axis provides accurate results for kshana compared with the spinning solid sphere and shell model. Thus, Maharishi Vyasa’s definition of kshana helps us understand the nature and structure of electrons.
5. Conclusion
The quantum time kshana is a natural unit of time, such as day and night, based on the rotation of the Earth on its axis. Value of a kshana found by a fundamental process, such as spinning, rather than by a length coordinate is proportional to the radius of the fundamental particle such as electron, and it decreases with the decreasing radius. According to Maharishi Vyasa, a kshana is exceedingly small, indivisible, and constant. Therefore, more research on this natural unit of time kshana is possible in future. Maharishi Vyasa’s definition of kshana opens the possibility of a new foundation for the theory of physical time, and new perspectives in theoretical and philosophical research. “Kshana” which is in zepto-second, that may be achieved with any direct measurement.
