Spacetime

He notes that it is his disbelief in the existence of past and future objects that drives him to adhere with the presentist view. Relativity’s four-dimensional manifold of space-time points is just a “theoretical entity” (Zimmerman 219) that lives within the context of a scientific theory, it is nothing but a concept, one that a presentist should be free to employ. As a presentist, he can continue conceiving of what exist only in terms of the particular privileged slice that is the present within the 4D manifold. How the future forms will be dependent on what the present is like, and given that the 4D manifold of spacetime points is conceptual, the “important spatiotemporal structure of a straight line in a time-like direction” (Zimmerman 219) can likewise be a line composed of the conceptual points, of where a particle in the present would go, and from where it could have arrived, in the absence of external forces acting upon it. What their status as “conceptual” means is that the presentist doesn’t actually posit these points to exist, but they exist within the context of STR, which he accept as a concept. Since in this reconstruction a straight line running in a time-like direction can be composed, the problem presented by the B-theorists in the paragraph above, becomes largely…

Eliot explores a myriad of interpretations of the meaning of logos in the Four Quartets through Einstein’s theory of Relativity, by examining it through the bending of space and time, ultimately using this lens to arrive at the conclusion of the Incarnation. This curvature of spacetime opened the doors to the reality of a new method of understanding the world: non-Euclidean Geometry. Non-Euclidean Geometry differs from several key postulates of traditional Euclidean Geometry. These reworked…

The speed of light is the ultimate speed limit in the universe. Which travels at 3.0 x 108 m/s in a vacuum and always moves in a straight line. When light travels to a new medium its speed and direction will change, this is called refraction. Materials have different optical density so light rays travel at different velocities. Refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium. Calculated by the velocity of light in vacuum divided by velocity in a…

1 The Nature All my life through, the new sights of Nature made me rejoice like a child. – Marie Curie (1867-1934), the Polish-French physicist chemist famous for her pioneering research on radioactivity. She was the first person honored with two Nobel Prizes in physics and chemistry. All that is beautiful, delightful and affable in this world, the silence of the night, the loveliness of the morning, the beauty of the day, the melody of the breeze, the fragrances of the flower, the precious…

Research Question Is the Physics in the movie Gravity accurate? Does it adhere to Newton’s laws? Introduction The purpose of this task is to find out if the science behind certain scenes in the movie Gravity is accurate, compared to what Newton’s laws suggest would happen in real life. The film Gravity is largely set in space, 600km above the Earth – according to the movie. Hypothesis The Physics in the movie Gravity is accurate, as it complies with Newton’s Laws of Motion in the context of…

Julius Robert Oppenheimer is remembered as a well-renowned citizen-scientist whose efforts in the field of theoretical and experimental physics produced a cornerstone in weapon development and the knowledge of the atom, but what can we say accounted for Oppenheimer’s success in his endeavors? Was it his drive for the knowledge of science, or was it the patriotism he had for his country that drove him to work endlessly on the creation of the atomic bomb? In an article in Modern American Poetry…

In the following, I will argue that Einstein’s discovery of the theory of special relativity was ultimately positive in terms of its benefits. First, Einstein’s discovery changed our understanding of space and time. Second, Einstein’s discovery has a positive effect on people’s daily lives, for example, the global positioning system (GPS). Third, Einstein’s theory of special relativity is a scientific theory, which according to dictionary.com is “a coherent group of propositions formulated to…

Academic efforts such as Beyond the Multiplex：Cinema，New Technologies，and the Home (2006), Reinventing Cinema：Movies in the Age of Media Convergence (2009), Hollywood Gamers：Digital Convergence in the Film and Video Game Industries(2010), The Art of Immersion：How the Digital Generation is Remaking Hollywood，Madison Avenue，and the Way We Tell Stories(2011) and 21st-Century Hollywood：Movies in the Era of Transformation(2011) demonstrates a lot about how film develops in the contemporary digital…

Introduction The Time Machine and the Sound of Thunder are both science fiction stories. Their central plots are about Time Travel. Compare and contrast these two stories. This assessment has asked me to compare and contrast the stories of The Time Machine by H.G. Wells and The Sound of Thunder by Ray Bradbury. In this assignment the differences in language and characters will be compared and contrasted. The genre of the short story will be contrasted with the short novel. The different ways the…

How to define a hero? A hero could be a world saver, like what Marvel Studio describes; a hero could be someone that changed the world; and a hero could also be a person who significantly affects individuals. Three persons, who influenced me a lot, are considered as my heroes: John Owen-Jones, Isaac Newton, and Albert Einstein. John Owen-Jones, a popular Musical singer, not only influences my singing style, but imperceptibly encourages me to think deeper towards Musicals as well, which leads me…
