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 Continue reading...

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 Continue reading...

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 Continue reading...

Newton`s contribution to physics

Newton studied all the basic questions of physics and mathematics relevant to his time. 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 Continue reading...

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 Continue reading...

Herefrom, I will try to explain its importance for the future of particle physics we know nowadays and try to adumbrate its organization, principles of work and Continue reading...

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 Continue reading...

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 Continue reading...

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 Continue reading...

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 Continue reading...

Heliopause boundary penetration between the interstellar medium and the solar wind allows in measuring interstellar fields, Continue reading...

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 Continue reading...

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 Continue reading...

Summary

Bilal Haq, a scientist from the National Science Foundation Arlingtion, Virginia encountered foraminifera on his trip to Qingdao in China. Foraminifera are small creatures that grow shells on their bodies. Their shells are varied and very diverse, as if they are created by visionary artists. Haq thought the foraminifera would make beautiful pieces of art and should be put on display.
