     The movie Contact makes an effort to display a realistic representation of the Twin Paradox, but the fundamental concept of time dilation was displayed incorrectly. The time dilation in the twin paradox is a result of the point of view of a stationary observer seeing a clock move slower as it moves with a constant velocity past them. This can be portrayed in the diagram below:      Keep in mind that light in a vacuum will always travel at the speed of light [c], which represents the second postulate of special relativity. The second section of the illustration above represents the actual motion of a photon in both a moving inertia frame and a stationary inertia frame. The third section of the illustration represents what a stationary observer would see as the clock moves by them at a constant velocity. Notice how the distance that the photon actually travels (2d) is shorter than the distance that the stationary observer sees. To the stationary obs...

The Indiana Jones movie series is full of scenarios where characters use ropes, chains, and whips to swing from one place to another. From a physics perspective, this swinging motion is a perfect example of the law of conservation of mechanical energy. The law of conservation of mechanical energy states that the total potential and kinetic energy in a system will remain constant as long as the only forces that act on the system are conservative. This law can be written as follows: KE i +PE i =KE f +PE f Where the initial and final mechanical energy is measured at these points in the swing path: Classic Rope Swing When starting from rest in the initial position above, the only energy in the system is in the form of potential energy, since kinetic energy is associated with movement. At the bottom of the swing, there is solely kinetic energy in the system since the bottom of the swing path is considered at ground level. Therefore, the change in potential energy as it d...

     The film industry is notorious for defying the laws of physics, especially the laws of space physics. In  an effort to make scenes more action filled or possibly due to lack of physics knowledge, film makers will give space certain properties and characteristics that it does not possess. Philip Plait, also  known as "The Bad Astronomer", wrote a list named "Top Ten Examples of Bad Astronomy in Major Motion Pictures" which lists the ten most common mistakes that Hollywood movies make in displaying the physics of space.      I put the movie "The Martian" to the Bad Astronomy test and chronologically noted each time the movie tested an example that Philip Plait provided in his list. The first Bad Astronomy example that the movie tested was the fourth one, which speaks about the properties of light and lasers in space.      Philip Plait claims that movies wrongly show light propogating space as though space is filled with...

     One of the most appealing aspects of science is that it allows humans to excercise their curiosity. Many scientists remain curious because they often make discoveries that they never expected to discover. They also want to gain a better understanding of the universe around them; often forming theories and trying to prove them based on observation, or observing and making theories about natural laws that cause what they see to occur. But what is the fun in making weapons of mass distruction? What is the curiosity that they are trying to satisfy?       Science is also practiced because it is necessary to better human existence. We need research in science so that we can find solutions to new problems that pop up. Global warming, plastic pollution, and overpopulation are all things that we need new science to deal with. But what do we need to develop weapons of mass destriction for?            If someone needs to...
