Quantum Mechanics

Erwin Schrodinger is one of the pioneers of quantum mechanics and from his works, it is evident that the physicist proposes a question on what happens when you place a cat in a box in the presence of a device that has a 50% chance of killing it the next hour. Understanding physics describes the cat experiment as a paradox. The scenario is this video is similar to a presentation of a simultaneous cat being dead or alive.If the cat in the box survives, does it remember that it was alive? This experiment leaves us in a mixed state in which our intuition demands that the observer can only be in a mixed state with the cat being such a mixture. Is the cat expected to be an observer too or does the existence of the cat exist in a well-defined classical state that requires observation by an external observer? Each of these alternatives did seem ridiculous to Schrodinger in his experiment.

One of the most breath taking facts that Einstein presents to us in his experiment lies in the trust that everything present in the globe from electrons to light to atoms all behave like a wave and a particle at the same time.A fundamental question that arises after watching his video lies in how he manages to conclude in this manner. This experiment reveals to us how atoms and other molecules are in an entangled state. Being in an entangled state therefore explains why atoms behave in the same way. His explanation on the equation for the overall theory of relativity is the main background that explains why particles behave in the same way. From this experiment, it is evident that the influence that one particle has on another is understood from the law of universal gravitation. The theory on this video I think provides a unified description of how gravity operates as a geometrical property of time, space and space-time.

Central mystery of quantum mechanics could be summarized from a lineage of how physicistshave pieced together the puzzle that reveals that dual nature of planet earth. In an animated primer, this video reveals classical physics and how it occurs in our everyday lives. Modern physics in this video mostly deals with particles that are fast moving or are in the presence of robust forces of gravity. The video producer is keen to point out that the quantum mechanics in modern physics have been woven into the modern life fabric. Viewing this video, it would be impossible to understand the nature of a quantum electron without an understanding of how semiconductors chips work in computers. This video describes a world that is entirely bizarre; a world that nothing is completely certain and objects should not be defined to have definite properties until they are measured and that is the central mystery of physics.

Samani Josh in his understanding of Schrodinger’s cat decides to teach us what quantum mechanics means from the cat’s experiment. From the cat’s experiment, we tend to develop a belief that the cat is both alive and dead when inside the box but there is a deeper meaning of this experiment as explained by Josh. Common sense reveals to us that this understanding is not true and Josh on the other hand uses this experiment to reveal to us how Schrodinger used the cat to point the limits of the Copenhagen understanding. Whether or not it is observed, the cat is dead or alive. This experiment inhibits us from having a naïve acceptance of this model as a blurred one. This experiment is actually used to illustrate the distinct nature of theories used in quantum mechanics and how these theories should be approached.

Watching the video on Heinsberg uncertainty principle, we get the view of a principle that revolves around indeterminacy. This principle from the video reveals that velocity and position could not be measured both at exactly the same time. I believe this theory is derived from measurement of a problem that reveals an intimate association between the particle and the wave in quantum objects. It is expected that a transformation in velocity of an atom could be more ill-defined when the wave function is confined to minute region. This theory would have so much depth when we ask the query‘is what we know about reality unlimited’? The answer would be not since the principle of uncertainty from this video determines that there is a built in unpredictability about nature.

In his video presentation, Dr. O’connell presents an example to his audience involving a large, visible object that can be seen by the naked eye and has the ability to be in 2 places at the same time. This presentation could be limited in evidence because in physics, only particles that are disciples of the quantum mechanics theory have the ability to be in two places at one particular time. In his video, Dr. Connell tells us that if everything is comprised of little particles that follow the quantum mechanics process then everything else within the object automatically follows the process. Unlike Dr. O’connel who does not believe in interconnection for quantum mechanics to be complete, I believe interconnection happens in our day to day lives and the mere things that surround us must be connected to have some flow.
