Essays on Physics

The interest in space and space travel increases with the influence of the films taken, which in turn leads to the question of how applicable the concepts in such films are. In this article, let’s take a look at whether the artificial gravity spacecraft mentioned...

The Greek philosopher Aristotle (384–322 BC) posed, following earlier traditions, that the material world consisted of four elements: Earth, water, air, and fire. For example, a rock was mostly Earth with a little water, air, and fire, a cloud was mostly air and water with...

Isaac Newton discovered it. If you don’t like the word ‘Newton’, then let us say Isaac discovered it.  Gravity is a unique insight in the history of human thought. Never before Isaac Newton, anybody in their wildest dreams thought that there could be a single...

Abstract Green solid state emitters with good internal quantum efficiency are a major concern in order to get white light by colour mixing. InGaN being a potential candidate for green emitter has been studied here. Shorter wavelength emitting LEDs, in visible range, made of III-nitrides...

Abstract The topic of this paper that I want to specifically talk about is Newton’s Second Law of Motion and how his theory would show how the forms of mass, acceleration, and force would all coexists amongst each other whether that be finding the acceleration...

Sometimes, we wonder, “What causes movement?” or “How do things move?” All this is explained in “Sir Isaac Newton’s Laws Of Motion”. In this essay, I will be talking about and explaining these laws and how they are more relatable to our lives that we...

Sports are most easy and convenient ways for the very good physical and mental exercise. Sports bring a lot of benefits to everyone. Sports provide a person the feeling of well-being and encourage living a healthy life. It keeps us fit and healthy as away...

Introduction The counter movement jump (CMJ) has become a commonly used indicator for assessment of an individual’s “physical fitness, specifically lower limb power and strength which has been utilised by both the general population and high performance sports”. The vertical jump height is measured as...

There are many numberless stories of science and till to date most of them are demystifying, and out, darkness is one. So far, no one can decide what darkness is and from where it continues to exist and why rights are overbearing to remove darkness....

Time and time again, the evolution of math continues to expand. Since the mid 1600’s, there have been many math scholars, but not one comes in comparison with Sir Isaac Newton. Newton was a very influential person in life, and at work. Isaac Newton, was...

We demonstrate for first time that ultrasound exposure at therapeutic frequency in continuous or pulsed mode, is able to reduce hepatic injury in the setting of partial hepatectomy with vascular exclusion. Importantly, this study enlightened that therapy based on pulsed ultrasonography at 0. 8 MHz...

A new kind of supervised learning approachis proposed to determine the number of occupants in aroom in order to use these estimate for improved energymanagement. It introduces the concept of Parametrizedclassifier. It relies on the predetermined structure ofsupervised learning classifiers, where any classifier couldbe used...

Abstract The existence ofsecond-order structural phase transition in the SnSe at a pressure of10GPa has been proved theoretically. The calculation is performed using the plane-wave pseudopotential approach to density-functional theory within the local-density approximation (LDA) withthe help ofthe ABINIT software package. Theabrupt change inbulk module...

Biomechanics examines forces acting on the body, and the effects of these forces CITATION Aus16 l 3081. The materials that make up the perfect baseball bat have been developed quite rapidly over the years dating way back to the very first MLB game early in...

Introduction In recent years youth tennis has become increasingly competitive across all levels and ages. Recognition of the importance of physical preparation and development in youth tennis has also grown. Therefore, effective modalities which improves physical attributes pertinent to performance is crucial. The serve is...

The history of power generation is long and convoluted, marked by myriad technological milestones, conceptual and technical, from hundreds of contributors. This report will look at all the power generation sources conventional and non – conventional from a historic, economic, technological and safety perspective and...

Sound production in the Lepidoptera is reported in adults and larvae through a variety of different mechanisms, depending on species. A recent comparative analysis has identified four distinct types of sound production mechanisms for caterpillars from the Bombycoidea superfamily, including whistling, chirping, clicking and vocalising....
