Mathematical Models of Spacetime in Contemporary Physics and Essential Issues of the Ontology of Spacetime ABSTRACT: The general theory of relativity and field theory of matter generate an interesting ontology of space-time and, generally, of nature. It is a monistic, anti-atomistic and geometrized ontology — in which the substance is the metric field — to which all physical events are reducible. Such ontology refers to the Cartesian definition of corporeality and to Plato's ontology of nature
all the evidence left at the crime scene and work backwards to deduce what happened and who did it”(Budd1). In order for the officer to find out how fast the car was going at the scene he needs to solve an inverse problem. “Inverse problems are mathematical detective problems. An example of an inverse problem is trying to find the shape of an object only knowing its shadows ”(Budd1). In addition, a day on the job of being a cop. There is a car accident and the officer job is to figure out if the car
In general, experimenting with models requires less time and is less expensive than experimenting with the real object or situation. A model airplane is certainly quicker and less expensive to build and study than the full-size airplane. Similarly, the mathematical model in equation (1.1) allows a quick identification of profit expectations without actually requiring the manager to produce and sell x units. Models also have the advantage of reducing the risk associated with experimenting with the
1.9.1 Sensitivity analysis of the model Sensitivity analysis is the study of how the uncertainty in the output of a mathematical model or system (numerical or otherwise) can be apportioned to different sources of uncertainty in its inputs. A related practice is uncertainty analysis, which has a greater focus on uncertainty quantification and its propagation. Ideally, uncertainty and sensitivity analysis should be run in tandem. As the optimization method provides the best set of inputs for optimum

This paper presents the study of non-linear dynamic of cardiac excitation based on Luo Rudy Phase I (LR-I) model towards numerical solutions of ordinary differential equations (ODEs) responsible for cardiac excitation on FPGA. As computational modeling needs vast of simulation time, a real-time hardware implementation using FPGA could be the solution as it provides high configurability and performance. For rapid prototyping, the MATLAB Simulink offers a link with the FPGA which is an HDL Coder that
I Wish to Pursue an MS Degree in Electrical Engineering During my senior year at Purdue University, I made a decision that has impacted the entire course of my education. While my classmates were making definite decisions about their career paths, I chose to implement a five-year plan of development and growth for myself. I designed this plan in order to examine various careers that I thought might interest me, as well as to expand upon my abilities at the time. As I was attaining a BS degree

Math also plays a key role in this theory. “The more we learn about the universe, the more it appears to be based on mathematical laws.”(Moskowitz). Who knew a simple equation could make up our entire
Simulations "What I hear, I forget; what I see, I remember; what I do, I understand." Confucius, 451 BC General As young children, we all learn by doing. Toddlers learn to walk on their own with their parents standing by as guides, providing a safe environment that makes it possible for the child to learn. When a child enters the "formal education" system, unfortunately this rich environment of learning by doing often disappears. The education system is still stuck in the industrial age
The Simulated Reality Hypothesis The simulated reality hypothesis is a simple idea that says that we, and everything in the known universe, is currently living inside a computer simulation. This idea has been talked about by philosophers for centuries and even has some ties to religion. Sci-fi writers have been writing about simulated reality for years and we have seen it visualised on tv shows yet the idea that we may be living inside of a computer simulation is almost unknown to most people.
1) In your own words, define a mathematical model. Describe the stages involved in the formulation of mathematical models. Mathematical modelling is when a person or group uses past data and mathematical methods to predict or model future events or behaviour. This simply means that somebody looks at what has happened previously, does some maths and is then able to work out what might happen in the future. In order to create a mathematical model there are a number of steps that need to be taken: Description
From ancient times, philosophers were obsessed with learning about the heavens and the world above so that they may be closer to God or heaven. According to global.bricannica.com: “Ptolemaic system, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about AD 150 and recorded by him in his Almagest and Planetary Hypotheses. The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that the Earth is stationary and at the centre
Countless time teachers encounter students that struggle with mathematical concepts trough elementary grades. Often, the struggle stems from the inability to comprehend the mathematical concept of place value. “Understanding our place value system is an essential foundation for all computations with whole numbers” (Burns, 2010, p. 20). Students that recognize the composition of the numbers have more flexibility in mathematical computation. “Not only does the base-ten system allow us to express arbitrarily
This chapter will mainly discuss about Black Scholes model, which is applied in this research. The history of Black Scholes will be introduced followed by Geometric Brownian motion equation history. Besides these two, we will also explain briefly about financial application of gold share price. 2.2 Gold Share Price Shahriar Shafiee (2010) is concerned about global gold market and gold price forecasting. He stated that in practice, the price and production behavior of gold differs from most
The first step in learning mathematics is to look over the materials provided, usually a textbook. Locate the glossary. The glossary will have the definition of mathematical terms used in the text. If the text does not have a glossary, locate the index. The index can be used to find the page that contains the definition of a mathematical term. Also, review the table of contents. If the textbook contains a section about ways to successfully use the textbook or a section containing tips for mathematics

Delving deeper into the axioms and theorems one realizes that theorems rely on logic, and can be proved or disproved using axioms. However, axioms often rely on empiricism as a way of knowing. Going back to Euclidean Geometry , the fifth axiom stated that if two lines are perpendicular to the same line they are parallel to each other. The proof of this observation could not be provided using any other axioms or theorems, and was included by Euclid on the basis of common observation. This was widely
One of the many books I have read about running a construction business and how to perform and create successful financial sheets to make sure your business is doing well is through a book I read this semester called, A Simple Guide to Turning a Profit as a Contractor, by Melanie Hodgdon and Leslie Shiner. Some background about the book is about a man who owns a residential construction remodeling business who is not doing financially well as managing and keeping track of the jobs with old school
In the field of art, artists always use techniques and methods to make their work better. The ‘Rule of Thirds’ and The ‘Golden Ratio’ are amongst the most important techniques in artwork. The ‘Golden Ratio’ is an ancient mathematical method. Its founder is the ancient Greek Pythagoras. (Richard Fitzpatrick (translator) ,2007. Euclid's Elements of Geometry.) The ‘Golden Ratio’ was first mentioned 2300 years ago, in Euclid's "Elements" .It was defined as: a line segment is divided into two
My first job was working at the Carmike Cinemas at the Summit. My main duty, among others at the theater, was working the concession stands. It was an entertaining job. It took me awhile to learn the ropes, but once I did, it was smooth sailing. There were several times the concessionaires stands were run by only one person. While it is fun working in a concession stand, I couldn’t forget about my responsibilities. A rush of thousands of people is a daunting task, but it will go smoothly if my station
