Space and TIme

Many people wish that they could go back in time and change something that they have done; even if it was a small mistake, or a large one that changed their life forever. Science is trying to prove that time travel does exist using the Space-time continuum. With controversy on both sides, scientists have proven that the space-time continuum does exist; however time travel is still up for debate. How Space-time was created For a long time we saw space and time as two separate entities. Many very sound theories existed before the space time theory came about. Some of those theories were Isaac Newton’s theories of mechanics and James Clerk Maxwell’s theories on electromagnetism. Though these theories never quite…

Contrasting the View of the Ultimate Reality in Relation to Science

What compels mankind to seek unity between, science and religion, two compartmentalized and distinct aspects of our world? John Polkinghorne states, in “Does God Act in the Physical World”, “The demand for an integrated account of both theological and scientific insight impels us to the task” (Polkinghorne 59). Yet Polkinghorne is not alone is his quest; in “Emptiness and Form” Fritjof Capra connects the ultimate reality with the physical world. While Polkinghorne and Capra agree on certain ideals, such as the man’s inability to fully grasp the ultimate and the incorporation of quantum mechanics in each one’s respective argument, they also contrast in terms of the religions they use to defend their argument. This leads to differences in their views…

Investigatory Project in Physics

Elastomeric Grating for Wavelength Switching Elastomeric Grating for Wavelength Switching in Optical Communication Systems. A diffraction grating was fabricated from an elastic polymer. It was patterned after a plane reflection grating with a pitch of 1,200 lines/mm. It was characterized using HeNe laser to verify grating properties. Angular scanning as a function of applied strain was observed for two individual wavelengths. Intensity of the fiber output was optimized as an application of angular scanning in fine alignment. Beam profiles showed consistency of first order diffraction intensities at different levels of strain. This showed that the elastomeric grating’s efficiency is independent of strain. The elastomeric grating’s variable pitch can be of immense utility in optical communicationsystems.A stretchable grating can be used…

Modern Physics

Solving Schrodinger’s equation gives the particle’s wave function. How are physical observables obtained from the wave functions? Use momentum, position and kinetic energy as examples to demonstrate that. The third postulate in Quantum Mechanics states that every observable in quantum mechanics is represented by an operator which is used to obtain physical information about the observable from the state function. This means that the use of an operator in the equations can obtain the observables such as position, momentum, and kinetic energy from the wave functions. The position of the particle, as well as energy, is an observable quantity which can be determined from the solutions of the time independent Schrodinger equation: HФ = EФ where H denotes the Hamiltonian…

Physics And Engineering In I.T. Power Management

The cost of energy continues to increase with shrinking in corporate budgets and need for more energy input. At times like this, even IT industry is affected and the stakeholders are starting to look for new ways of cutting down the cost as they keep the quality of work high and efficiency maximized. Implementation of a good energy policy in an organization’s premises can lead to reduced costs of ICT infrastructural costs in terms of capital required in setting up servers and cooling systems. If the right energy saving and proper utilization habits are adopted and effective construction and installation ideas implemented in natural air flow optimization and proper heat insulation can lead to less cooling facilities requirements, cutting on…

Albert Einstein as Father of Modern Physics and Isaac Newton as Father of Classical Physics

Newton was known as a natural philosopher during his life but his theories of motion, gravity, light, etc formed the cornerstone of what would become known as physics. He probably contributed more to the science than any single person before or after him. Newton’s 1687 publication of the Principia is considered to be among the most influential books in the history of science, laying the groundwork for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion which dominated the scientific view of the physical universe for the next three centuries. Albert Einstein (Father of Modern Physics) Albert Einstein was one of a group of physicists in the early part of the 20th…

Physics

Physics is a diverse area of study and in order to make sense of it scientists have been forced to focus their attention on one or two smaller areas of the discipline. This allows them to become experts in that narrow field, without getting bogged down in the sheer volume of knowledge that exists regarding the natural world. Below is a list – by no comprehensive – of different disciplines of physics. The list will be updated with new additions and definitions as appropriate. Acoustics – the study of sound & sound waves Astronomy – the study of space Astrophysics – the study of the physical properties of objects in space Atomic Physics – the study of atoms, specifically the…

Ohm’s Law Series-Parallel Circuits Calculation

To end up the discussion of Series-Parallel Circuits, I would like to post this last one remaining topic which is about Ohm’s Law of Series-Parallel Circuits for currents and voltages. I did not even mentioned in my previous topics on how to deal with its currents and voltages regarding this type of circuit connection. Ohms Law in Series-Parallel Circuits Ohm’s Law in Series-Parallel Circuits – Current The total current of the series-parallel circuits depends on the total resistance offered by the circuit when connected across the voltage source. The current flow in the entire circuit and it will divide to flow through parallel branches. In case of parallel branch, the current is inversely proportional to the resistance of the branch…

Cartesian Diver

“Cartesian” is named after the French mathematician and philosopher Rene Descartes, who lived from 1596 until 1650. Cartesian diver lab is used commonly in scientific experiments to illustrate principle of buoyancy. The objective of this Cartesian diver lab is to demonstrate Pascal’s law and Archimedes’ principles. Observation is the key to conduct this experimental study of the Cartesian diver. First a 2-liter bottle is filled with water to almost all the way to the top, then prepare the diver which is a test tube, fill the test tube about 50-60% with water, place the diver inside the bottle the diver should float near the water surface then secure the cap on the bottle. When the container is squeezed, the diver…

Leadership strategy that supports organizational direction

Organizations need leadership strategies in order to create confidence for employees and other stakeholders that there is a clear direction in which the organization aims to head. Understanding leadership culture is the first stage to creating an effective leadership strategy; the next step is to assess the relationship between staff and their leaders and bring emotional intelligence into play, this will become a necessity for leaders in creating their strategies (Gordon n.d). The retail store Diamond relies on different leadership and management theories but the selected theory of discussion is the Open Systems Theory. The impacts of different theories of management and leadership used within the retail industry is countless. A retail company like Diamond utilizes multiple theories in order…

Purpose: To prove Faraday’s Law of Induction using an oscillating wand which swings through a magnetic field. In addition, we studied the conversion of mechanical energy to electrical energy. Questions: 1. What are the possible errors in this experiment? There are a variety of sources of error which may have affected the results of this experiment. There could have been an error in the setup of the Rotary Motion setup or its setup within the Logger Pro program. Another issue with the setup could have occurred when using the banana plug if it was not inserted correctly. In addition, errors could have occurred during the collection of data such as not pulling back the oscillating wand properly to get an…

Sample Concept Paper

For John Wheeler, defining the term “quantum” in his essay “How Come the Quantum” (Best 41-43) seems the least of his worries. It’s a “thing,” he says, “a bundle of energy, an indivisible unit that can be sliced no more” as Max Planck’s observations 100 years ago indicate (41). Wheeler’s words ‘thing,’ ‘bundle,’ and ‘sliced’ are interesting: they seem at once colloquial and correct for the usage Wheeler makes of them. Quanta sound friendly, everyday. The just-folks tone continues as he observes that, thanks to quanta, “In the small-scale world, everything is lumpy” (41). He moves his readers forward smoothly (no lumps) to the next topic, what existence of quanta reveals about the uncertainness of the world, a world where…

Synthesis of Acetaminophen

Introduction The synthesis of Acetaminophen is based on the amine group of p-aminophenol being acetylated by acetic anhydride to form an amide functional group. Acetaminophen is isolated as a crude solid which is then recrystallized to purify the product. Using melting point determination the recovered products purity is identified and can be compared to the theoretical value. In this experiment 3.0g of p-aminophenol along with approximately 10ml of deionized water will be heated in a water bath regulated at 65-75. After heating for 5 minutes 4.0mL of pure acetic anhydride will be added to dissolve the p-aminophenol. Following this there will be continuous heating in the regulated water bath to ensure all p-aminophenol dissolves. Gradual cooling will lower the mixtures…

Amusement Parks Are A Great Place

Amusement parks are a great place to see Newton’s laws of motion in action. Choose your favorite ride and describe the parts of the ride that illustrate each of Newton’s laws of motion. You are only required to give a written description; however, if you would like, you may draw and label a picture in addition to the paragraph explanation. I’m using a roller coaster for my example. 1.) The roller coaster doesn’t move until force is used upon it. 2.) When the roller coaster goes down after reaching a very high point in the ride, gravity makes it speed up. 3.) The roller coaster is on top of the track, the track applies a opposite or equal force on…

Emotion and New York

In Proof, there is a contrast presented between the abstract and tangible aspects of life. Claire’s life revolves around everything that is practical while Catherine relies more on things that are theoretical. These choices cause problems in each sister’s life in that they are both disconnected from the real world and neither can relate to other people, including each other. Catherine focuses on the theoretical, letting her life revolve around things that are not tangible, things that other people cannot necessarily see. Early on in the play, Catherine figures out that the number of days she has wasted because of her depression is a mathematically significant number. Math is a very abstract science and this scene shows how mathematically minded…

Conservation of Momentum Practical Write Up

AIM: To investigate if momentum is conserved in two-dimensional interactions within an isolated system. HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction. METHOD: An air hockey table was set up and a video camera on a tripod was placed over the air hockey table. The camera was positioned so it was directly above the air hockey table facing downwards. The air hockey table was turned on and two near identical pucks were placed on the table, one at one end of the table and one in the centre. The puck at the end of the table was…

Expansion and contraction of matter

Thermal Expansion and Contraction Most of the matters, without some exceptions, expand with the increasing temperature. When you give heat to matters; speed of its particles increase and distance between them also increase which results in the increase of the volumes of matters. All expansions occurs in volume of the substance however, sometimes some of the dimensions of them expand more with respect to others. In this case we neglect the less expanded ones and assume expansion like linear expansion in long materials. Moreover, we take the expansion of plate as area expansion and finally we take the expansion in three dimensions as volume expansion. thermal expansion Inverse of the expansion is called contraction, generally when matters lost heat and…

My First Time Peering Through a Telescope

When I was eight years old, I peered through a telescope for the first time in my life. It was a small device, no more than two metres long, and yet it let me glimpse a brilliant view of Jupiter: it was the size of a marble, magnificently striated in hues of brown, red and orange. Then, when I was 13, I went to the Birla Planetarium in Hyderabad, where I revisited my five-year old fascination with Jupiter as I sat spellbound in the arena as a cosmic dance played out in the canvas stretched above my head: stars flew around, tumbling in and out of the horizon, the rings of Saturn floating serenely in space, moons rising and setting…

Mastering Physics Assignment 1

1. History helps us understand people and societies because it provides an explanation of how and why people do what they do. The wars fought and laws passed all have reasons and those reasons are still relevant in modern day society. 2. History helps us understand change and how the society we live in came to be because it provides factual reasons why people are how they are and what they came from. The different ways that people would live provide the foundation for the way we live today. 3. History contributes to moral understanding because of the different advances that people have made learning right from wrong has changed with each generation and I will continue to change as…
