Spacetime

of a particle with the world line shown below? Viewing spacetime this way allows us to formulate physics in new ways. It is a similar way in getting Newton’s first law of motion, which states that an object with no force acting on it will move in a straight line at a constant and we can just say that the world line of a free object (one with no forces on it) is a straight line. speed (Harrison, pars. 6) Comparing to Newton’s laws, spacetime are considered two separate things, while in relativity

many, this is portrayed as the first known instance of suggesting space and time to be joined together as one thing. Albert Einstein's 1905 theory of special relativity is the very beginning of a theory related concept of spacetime, but the first mathematical theory of spacetime actually created by one of his own early teachers named Hermann Minkowski. He created the concept of “Minkowski Space” which is the earliest recommendation to the treatment of space and time as two separate entities of one

Is time objective, subjective, real, or unreal? Time is subjective, but real. The most direct knowledge we have of time is subjective. Time is a continuous process, it involves a sense of passage. The very essence of time as most directly, most concretely experienced, is the continuous unbroken passage of existence. According to Kant, time underlies all intuitions, as it is a singular unified thing. It is composed of many moments strung together like a movie reel. But that doesn’t mean that people

History and Philosophy of Science The world of science, as we know it today, is a difficult subject to grasp. So many new ideas are present and these new ideas are not interchangeable. Some parts do work together although as a whole they don’t fully coincide with each other. The three basic ideas that science is now based upon come from Newton, Einstein, and Hawking. I call these ideas/theories “new” based on what I classify the state of the scientific community of today. After looking at what

Manganiello focuses on the interplay between Dante and Eliot manifested in their use of the Incarnation. Drawing on the intent search of the confused speaker of The Waste Land, Manganiello proposes that the Four Quartets answers the search for the essential word with Logos. The epigraphs for Burnt Norton, the opening quartet, center around Logos and the intersections of time. Manganiello fleshes out Eliot’s exploration of time and eternity through the lens of the Incarnation. The Incarnation

zoologist. To understand general relativity, one must know how spacetime works, how black holes affect it, and how it affects humanity. General relativity is the idea that everything is made out of spacetime and that mass affects spacetime. One way to describe spacetime is by using a metaphor of a rubber sheet. The metaphor goes like this: a rubber sheet is stretched between two boards. A ball placed on it would bend the rubber sheet. Spacetime is like that rubber sheet and the ball is anything of mass

realized time dilation is a necessary consequence of keeping the speed of light in a vacuum constant everywhere in the universe, leading him to eventually conclude that space and time are not separate, distinct entities, but one linked dimension: spacetime. This single dimension, because it stretches and contracts, allows for unusual interactions between space

Physics. Not something you really hear every day. It’s not something you really want to hear either, right? Why is it that when we hear the word physics, it’s just a major turnoff. People may even hear the word and just think “get me out of here”, even though they may not have the slightest clue of what it’s about. Some people do have a slight clue and think molecules or gravity, atoms or Bohr, laws or life, and still may not quite grasp it, but at least have a slight clue. Others, think wasted time

With a name synonymous to genius, Albert Einstein is undoubtedly one of the most influential men in modern physics and philosophy of science. Who exactly is Albert Einstein? Born in the German Empire in 1879, Albert Einstein was not thought initially by his peers to be anything special. There is a lot of myth surrounding Einstein’s schooling with statements like “Einstein failed math” or “Einstein did bad in school”, but these were simply myths and not much more. Einstein did extremely well in school

Math, to Kant is synthetic because mathematical knowledge requires is true more than just definition. “All bachelors are unmarried” is analytic; “the bachelor down the street is untidy” is synthetic. This may seem odd; “1+2 = 3” seems to be analytic, as 2 is the sum of 1 and 1 by definition. Nevertheless this is illusory, according to Kant, because this is already a solved equation. When we look at an unsolved equation, we are presented with a problem. Take, for example 1+2 alone. We do not know
