4-Dimensional Space-Time and Holographic Universe.
Part-2: The Uncertainty Principle
On the basis of above discussed paradigms
we conclude as considering the basic foundation of quantum theory, we may,
sometimes, get into scientific fictional cross over with the beliefs that mankind
have ever adopted to himself, since before the introduction of the first
telegraph, the first radio, the first cathode ray tube, perhaps the first
electrical line or more precisely the evolution of the electricity itself.
Moreover we may phrase it as Science.
The sophistication in life by the
science that gave us revolution in the civilization from bicycle to invention
like Lasers, Radars, and Satellites up to the GPS systems, Transistors and the
touch sensed (electronics) gadgets, are all the comprehensive results of
Science. Well, of course, Physics is at the foundation of all the technology.
As discussed in previous blog the four forces of nature govern our universe and
yes, even our technology World Wide Web (WWW), Integrated circuit (IC’s) and
etc. are outcomes of mathematical equations of quantum theory/mechanics, or
result of thought experiment called
the Schrodinger’s Cat proposed by
the celebrated physicist Ervin Schrodinger. When we open up with quantum theory,
it is, mandatorily know about the particles, indeed after atomic and sub-atomic
particles, like electrons, study of its nature and their behavior, which is
called as Electronics, has revolutionized the world with technology.
The flow of electrons (current) is
as the result of particle application obliged in the technological era that we
live in. In fact the sophisticated life that we enjoy today might have not been
manifested by then. Now a days into the deep down of the sub-atomic world,
physicists have come to conjecturing the existence of some 200 sub particles
until today, and obviously the number is in increase in counts. Particle
physicists have divided all sub-atomic particles in three categories based on
their masses from lightest to the heaviest, they are as follows:
·
Leptons or light-weight
particles
·
Mesons or
medium-weight particles, and
·
Baryons or
heavy-weight particles
Let us dig deep into the
‘Particle Physics’ aspect as we are
already on to the mark to get start to travel into the very specific physics, to understand the
working of the universe and as discussed earlier technologies. All we feel,
touch, see and moreover, we, the human beings (Living things) itself are/is all
manifestation resulted from the tiny particle itself. For sure, human being is
made up of trillions of trillions of trillions of atomic and sub atomic
particles. In fact all the physical laws, those governing our nature governs
the human physiological life too. We can sense the touch, can feel heat and cold
scientifically we allow electric charge (current) to flow through our bodies,
accordingly even the beings are also called conductors.
But the
quest about the ultimate building block that can explain all the happenings in
this universe is yet unanswered. Perhaps what is Mass or Energy? What is
the mass composed of? What is the smallest particle composed of?
Well the new branch of physics, which is emerged very
recently, particle physics itself has
no answer and the quantum mechanics/uncertainty do have either. The most
celebrated physicist Heisenberg who himself formulated the ‘The uncertainty
Principle’, quoted in The Dancing Wu Li
Masters. Pg.216 as “In the light of the
quantum theory, elementary particles are no longer real in the sense as objects
of daily life, trees or stones”.
Heisenberg showed that subatomic entities like the electrons
can never be measured or determined in ‘conventional way’ and hence there is
and must always be a measure of ‘uncertainty’
or the ‘indeterminacy’ in our
knowledge of the electrons, and it is called as ‘Uncertainty Principle’. It summaries and try to determine precisely
the velocity and the position of the electron. But it isn’t
true i.e. if we try to know the position of the electron, then we will end up
with knowing almost nothing about its velocity, and vice versa. And hence this Principle
also called as of ‘Principle of Indeterminacy’.
The theory mainly insist us to make us to have a must knowledge to know the
electron we must know the Position (where it is) and what will be its velocity.
The ridiculous part of quantum cross over, comes in to picture, if one is known fully the other is bound to
remain unknown. As from the thought
experiment of the Heisenberg we can know that ‘something we have to use a light whose wavelength is smaller than the
piece of interest. So he (Heisenberg) thought to use the gamma ray to test
the theory, as the gamma rays will have the shortest wavelength. Moreover the
gamma rays got not only the short wavelength, got much more energy than
ordinary light too. So whenever gamma ray is focused on fast moving electron in
its orbits, it illuminates the electron with on doubt, but simultaneously it
violently knocks out the electron from its orbit and change in direction and
momentum occurs in an uncontrollable and unpredictable way. Heisenberg
mathematically calculated this quest in an equation:
Where Q= uncertainty about Velocity of the electron
P= uncertainty about position of the
electron
h= Planks constant (6.63*10-27 erg.
Sec)
This means
we could get both the velocity and the position of the electron with perfect
precision. But since the ‘h’, the planks constant is fixed quantity, either of
the uncertainty must remain.
