Physics Principles and Einstein’s Theory of Relativity in Modern Applications
Albert Einstein was among the most phenomenal contributors in the field of physics. He is well known for his contributions to relativity theory. Mandy is traveling to Rome and gazes outside the airplane’s window at an altitude of 20000ft above the ocean as the airplane starts descending to its destination. It was a long flight from New York to Rome, and as she stretched, her bones creaked as if she was getting old, yet Mandy knew that she was younger than her colleagues back in her country. The speed with which the airplane was traveling and the altitude of the airplane above made time for her to run slowly in comparison to her friends back in New York, although this was unnoticeable. The principles contained in Mandy’s scenario will be explained in relation to Einstein’s theory of relativity and its modern application in physics. The analysis will also offer a chance to point out my own experiences with the theory.
Several principles apply to Mandy’s scenario. In relation to the relativity theory and application in GPS location, the airplane is using a resistor that activates the GPS to facilitate control in the plane and control from the radar at the control center. The GPS location constantly locates the airplane and monitors its movement to keep it on track (Reed, 2017). Another relativity principle that applies in physics is how time elapses for an observer compared to an individual in the plane. A person moving fast sees time as passing more slowly than it seems for a stationary observer. This is evident in Mandy’s observation that time runs slow when an individual is at high speed. Also, time runs inversely proportionally to the strength of the gravitation force. Mandy mentions that time seems to pass faster for her than for her friends back in New York. This also brings the notion that Mandy is aging slower compared to her compatriots back at home. This is a phenomenon known as time dilation (Emspak, 2017). From Einstein’s perspective, Mandy’s assertion is justified.
The relativity theory also applies to electromagnets. The theory implies that electrons are passed through the conductor when a Direct Current (DC) flows through a wire. Without the theory, the wire would be neutral without a positive or negative charge due to the equal number of protons and electrons (Emspak, 2017). Putting two wires close to each other means carrying DC current will cause the wires to repel or attract each other, which depends on the direction of the current. Electromagnetism requires that the electromagnetic field should move at a finite speed rather than instantaneously through electromagnetic waves, making light and magnetism useful in equipment.
In my daily life, I use electronics that apply electromagnetism and other concepts from other scientists. The principle of relativism applied in transistors enables cell phones, computers, and coffee makers to operate. The GPS service I use to find directions to a new place also applies Einstein’s relativity. The service is also useful in taking measurements and calculating area, for instance, measuring the size of a piece of land or compound. The theory also helps me understand how gravity helps keep me on earth. Accordingly, it also explains the time movement between someone on a flight and me. Illustrated in my case and in Mandy’s case. Therefore, these happenings would not be comprehensible without the theories.

Scenario
Mandy took a trip to Rome, Italy. She gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination of Rome. It had been a long flight from New York to Rome, but as she stretched, and her bones creaked as though she was old, she knew that, in fact, she was a tiny bit younger than her compatriots back home, thanks to traveling at hundreds of miles per hour. In fact, time for her was running slowly compared to her friends in New York for two reasons: the speed at which she had traveled and the height of the airplane above the Earth. Neither, though, was noticeable.
