Title:
Fabric of the cosmos: Quantum Leap
Thoughts:
The Video discussed the physics at a quantum level, the Physics of smallest
particle of matter [atoms] and its sub-atomic particles; the way it behaves and laws of
physics it obeys. It is important first to note that the physics governing matter at macro
scale [classical mechanics] - the observable, predictable physics is different from that
of the atom [quantum mechanics] which works on bizarre ways and on its own laws.
The first few minutes provided an overview of the quantum world. Suggesting
that matter either ways behave both like wave and a particle. Bodies do exhibit a wave-
like characteristics as well although basically consists of particle but because it’s too
small we can’t even see it our naked eyes. However, on a quantum level to observed
these phenomenon is easy. Just like the light – the photon particles. The Double-slit
experiment explained and demonstrated that when a photon where allowed to passed
through ‘double-slit’ , if only treated as particle obviously it will land on just two points on
the screen but fascinating as it seems if doesn’t, rather it creates a series of patterns
known as interference patterns. Light diffracts and this phenomenon supported the
claim that it indeed acts as wave as well.
Going deeper on atoms, electrons exhibit the so called ‘quantum leap’. What is it
about? According to the Neil’s Bohr model a quantum leap is when an electron
leap/jumps or transitioned from one quantum state into another [energy level or shells].
Come to think of it like a solar system where electrons are found on orbitals with
nucleus at center. When electrons absorbed enough amount of energy from the
photon/light it jumps away from the nucleus [excited state] whereas when electrons
jump discontinuously to shells with lower energy on a ground state it emits/gives off
energy. But it can’t occupy space in between shells.
Equation of quantum mechanics helps precisely explain the behavior of particles
and atoms. Neils Bohr and Einstein had these conflicting views on reality of atoms.
Accordingly to Bohr he firmly believed that the reality is uncertain until we observed it
and that uncertainty say; location of photons on a double slit would disappear but to
Einstein he believed on certainty and reality would be as it is even without observer.
However, the late Einstein as well speculated that there is a missing theory that could
profoundly explain the nature of reality and certainty. Then comes this baffling theory of
quantum entanglement which furtherly studied by Einstein and which he also thought
that will complete and unified everything. It suggests that an entangled pair of electrons
with their properties linked with one another is connected in a special way. And that
whatever you do with one particle would definitely affects the state of its pair electron
they behave as if a single entity. Moreover, even if you stretched them away millions or
trillions of light years apart they would still appear to affect one another communicating
regardless how distant they were. Einstein referred this ‘spooky action at a distance’.
Considered a pair of electron spin. The quantum state is still uncertain unless
measurement is done on that entangled system. Without interfering or interacting the
system it will remain on its superposition with all its possible states. If one is said to be
spinning up most probably the other has an angular spin of a downward orientation in
space. Another, let us consider an entangled coin. If you happen to flip one and landed
head the other one is guaranteed to be a tail. It shows that the outcome of first system
