Did you ever wonder why wearing white in a hot summer day is more comfortable than wearing black? Or why some of the dark colors are viewed as hot colors and the light colors are cool? The answer lies in the adsorption of light of the materials depending on its color. A thermal energy source like the sun will converts its thermal energy into electromagnetic waves which will be transported to its receiver. These electromagnetic waves will be absorbed by the receiver and it will convert back into thermal energy or heat. The difference in the absorption properties of ...

Most shooting incidents in trailer and action movies portray a backward displacement of the victim (sometimes violent) over a large distance. Real life witnesses however may not give a similar account of the event. Viewers may also be skeptical on the way the incident is portrayed in movies. The effect of the bullet on the target can however be calculated from simple concepts in physics given the right or (reasonably approximated) quantities. The main concepts are those of momentum and energy conservation.
Firearms such as guns are meant to deliver destructive energy to the target with minimal energy input ...

Introduction

The subject about time and how time travels is really very fascinating. What is time? What is time travel? Is time travel really possible? We naturally know what time is since we sense it every day but we cannot seem to completely define it. The question of time travel is also very hard to answer. A deeper question is to ask if time is real. Another is to know if time just moves into one direction only. Does time have a beginning or an end? Up to now, we have never truly answered these questions with great satisfaction. By ...

Mighty apparatus of Newton`s mechanics, its versatility and ability to explain and describe a wide range of natural phenomena, especially astronomical, had a tremendous impact on many areas of physics and chemistry. “His study and understanding of light, the invention of the reflecting telescope (1668), and his revelation in his Principia of the mathematical ordering of the universe are all represented on his monument in Westminster Abbey” (“Sir Isaac Newton”).
Newton's influence on the further development of physics is enormous. Nowadays all scholars think ...

Introduction

The special theory of relativity is a theory proposed by Albert Einstein in 1905 that illustrates light and matter propagation at high speeds.

Einstein’s theory is based on two main ideas:

The principle of relativity: stipulates that the law of physics is invariable for anything that is in constant motion.
The principle of speed of light: stipulates that the speed of light is also constant for any object in any point from which it is being referred. This means that it the same for various observers regardless of their movement in relation to the source of light. Einstein established this principle after noticing a rational flaw in ...

Ludwig Boltzmann was an Australian physicist who is well known in the world of physics and Chemistry. The main fields that make him a well known person in the field of science are the molecular motion of particles in which he proposes that molecules must have thermal energy on top of other forms of energy for them to move (Klein 45). He contributed immensely in statistical mechanical physics and statistical thermodynamics. By evaluating amount of energy in molecular bodies, his influence stretched further to cover molecular chemistry.
One of the most remembered and significant theory is the H-Theorem. The ...

Methods of Heat Transfer

Conduction
The first method through which heat is transferred from one object to another is conduction. Conduction occurs in liquids and solids through transfer of kinetic energy present in one particle to the immediate particle(s) in its surrounding. By considering the bonds existing between atoms and molecules in solids as elastic links, the vibration of one particle due to increase energy level caused by heat, the next in its line vibrate too. This process is replicated in adjacent particles thereby allowing transfer of thermal energy from a body with a higher temperature as compared to the one with ...

My secondary curriculum experience was one memorable one. The memories are attributed to a number of factors. Among the factors include the subjects I did, the co-curricular activities in which I actively engaged, the social aspect I shared with my fellow students as well as the kinds of teachers that I had. What is most memorable to me, however, is one of my teachers in particular. The teacher, whose name is Mr. Aggrey, was my teacher of physics throughout my eleventh and twelfth levels.
I clearly recall the first day he was officially introduced as our teacher of Physics ...

What we accept as knowledge today is not always accepted as true tomorrow. Knowledge is more than a collection of facts on a particular topic. That is just information. Knowledge includes the assumption of a greater understanding as to how the facts work together. This means establishing connections between the facts, establishing meaning, providing evidence, considering the implications and arriving at a level of knowledge with a reasonable degree of certainty. This allows the assemblage of a body of knowledge that can be viewed from different perspectives and provides insight into a topic and how it fits into the ...

When comparing Western thought to the Eastern thought of Taoism, a ready example would be to contrast Newtonian physics to quantum physics. In Newtonian physics the laws governing celestial bodies are simple and understandable. One states that objects in motion stay in motion and objects at rest stay at rest unless an outside force acts on them. In quantum physics, the black and white of Newtonian physics turns grey. Electrons exists in a state of both being and not being and are governed by unpredictable laws that make it impossible for science to exactly pinpoint their location, which the ...

According to Knight (114) Aristotle is known as the Greek Philosopher who left a mark in the philosophical word. He learnt most of his philosophical ideas from Plato. In fact together with Socrates and his teacher Plato, most of the western philosophy is attributed to them. His philosophies were the first to left a mark in the western philosophy physics. Indeed even his student Alexander the Great became just as good as he was. Aristotle’s writing covered a wide range of topics including politics, morality, metaphysics, logic, aesthetic and science. Aristotle’s physics was quite impressive and they ...

Introduction

Resistivity is a parameter which defines the resistance of a metal to the flow of electric current per unit volume of the metal (Jones, n.d.). The resistivity exhibited by a metal is dependent on three physical properties; the cross-sectional area, length, and the nature of the material (A´ ngel & Tirado-Miranda, 2009). The value of resistivity dictates the conductivity of a metal, high resistivity is associated with low electrical conductivity while low resistivity means that the metal is a good conductor (The Physics Hypertext Book, n.d.). Therefore, it can be concluded that low resistivity allows for increased movements of electrons ...

The Higgs Boson is a theoretical particle which particle physicists have been attempting to isolate in order to measure its physical properties, namely its mass. Called the “god particle” by popular media, the discovery of the Higgs boson would validate the Standard Model of electroweak symmetry as it is the only elementary particle not yet observed by experimental particle physicists. The Standard Model has defined the properties and characteristics of the Higgs boson with the exception its mass. The discovery of the Higgs particle would thus give validation to the existing theory of six elementary particles which make up ...

Scientific background information

The Big Bang Theory is the cosmological model that explains how the current state of the universe came into existence. Scientific theories explain that approximately 13.75 billion years ago, the universe was dense, compact and extremely hot (Wollack 5). It then expanded rapidly releasing massive amounts of energy. The rapid expansion was followed by rapid cooling which resulted in the conversion of energy into sub-atomic particles (electrons, protons and neutrons) (Menegoni 13). According to scientific theories, the neutrons and the neutrons combined atomic nuclei minutes after the big bang to form the nuclei. According to Wollack, the electrons took ...

Introduction

Pumps installed in fire engines either hoses out water from the fire tanker or suck water from a source such as fire hydrants, lakes, or pools. Different mechanisms control the pumping of water from a water source to the scene of the fire. Usually, a 6 inch suction pipe is used to extract water out of the water tank or an external water source. The water is then discharged out through exit lines or hoses with a certain force to eventually quench the fire.

The Impeller Pump

The main source that pumps water is the impeller water pump. This is a propeller ...

Gravity is precisely defined as a pulling force; it pulls objects (matter) towards it. The intensity of force is directly proportional to the quantity of matter, so the things composed of more matter tend to be pulled with greater intensity of force. The mass of any object is the fundamental unit being used to measure the quantity of matter it that object. Therefore, the more heavy and matter in the object is, the higher gravitational pull will it put forth. Earth exerts a pulling force on the objects (Human beings) that move on its surface and as a result ...

What is science? If confined to the typical societal stigmas, science is a scientist in a lab, working for hours over a microscope with several chemical samples. If given a broader definition, science is all around us. It is in the way we breathe, or our biology. It is in the air around us, or the ecology. It is even in the universe that stretches so far beyond our feeble conceptions that we have had to develop a branch of science, theoretical physics, just to explain the missing links we do not understand yet. The book “Life, the Universe, ...

Meissner effect is one of the remarkable properties of superconductors. Most superconductors are metals and metal alloys. However, some non-metals also exhibit superconductive properties hence they are regarded as superconductors. A superconductor refers to a material that can transfer electric current with zero resistance. This implies that when electric current is passed through a superconductor at a temperature below the critical temperature value (Tc), no energy is lost in any form: sound, heat, or light. It is important to point out that superconductivity of a material can only be observed at temperature below the critical temperature (Tc). Critical temperature ...
