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…

Differences Among Cultures In the book Monique and The Mango Rains there are many situations that affect people, especially the health of women. All this involves the care, the place, among other things that are not favorable for them. To give you a better deal for patients Giger and Davihizer decided to make a proposal of the six phenomena which are: Biologic Variation, Social Organization, Time Orientation, Environmental Control, Space, and Communication. Transcultural nurse need to be able to…

Most people imagine time as a constant. Physicist Albert Einstein illustrated that time is an illusion that it is relative which it can differ for different observers depending on the speed through space. To Einstein, time is a fourth dimension and space is described as a three-dimensional field, which provides a traveler with coordinates such as length, height and width showing location. Time provides one more coordinate direction although conventionally, it only moves forward. Time…

Mallory James Lynette Burdick CHM 130 11 November 2015 Fritz Haber: For Better and For Worse Fritz Haber, a scientist not well-known to many, has played an immense role for our world today. This paper will describe him, his contributions to the chemistry field, the hardships he had to go through during his career as a chemist and the contradictions of his inventions. Fritz Haber was born into one of the oldest families of Breslau, Germany (now part of Poland) on December 9, 1868. Sadly, his…
