Geographical Location: Polynesia is located in the Pacific, an area of islands and ocean between New Zealand, Hawaii and Rapa Nui (Easter Island). The name itself Polynesia is derived from Greek words meaning many islands. A fitting name for an area containing over 1,000 individual islands, though only a handful of islands are currently inhabited. Hawaii, New Zealand, Samoa, Tonga,...

Safe Sound Level Practical Sound are waves produced by vibrations (OpenLearn, 2017). They can travel through solids, liquids and gases. However, the particles move differently in each of these forms. Sound waves travel fastest in solids, followed by liquids, then lastly gases (Oceanservice n.d). The molecules in solids are the most compacted, enabling sound to travel much faster in solids...

Since the publication of Said’s book Orientalism, travel literature has always been mentioned in association with colonial, and post-colonial literature. Jolanta Sztachelska claims that “the nineteenth century in Europe was the period of travel mania.” The purpose of this obsession with travel was very simple: profit with the leitmotiv commonly known as civilizing mission . For Nicklas Hållénm “travel literature...

Since ancient times, humans have navigated the waters surrounding them. As centuries passed, mankind has spread farther and faster. The best example of this widespread cross-Atlantic exploration is a period from around 1450 to 1650, aptly named the Age of Exploration. In this age, the Spanish and Portuguese sailed to the New World, around the coast of Africa, and even...

In antiquity, philosophers posited a variety of ways in which the physical world is constructed. One such philosophy is that of Atomism, which proposed that the universe was made of indivisible, granular elements: atoms. An early example of a philosopher proposing atomism is Aruni, a Vedic scholar from 8th century BCE India, who theorized that particles too small to be...

Niels Bohr, who was interested in explaining the spectrum of discrete lines that is observed when light is emitted by different elements. Many models of the atom have been proposed based on experimental data, including J.J. Thomson's discovery of the electron and Ernest Rutherford's discovery of the nucleus. Rutherford explained that in an atom, the nucleus is positively charged and...

Abstract Have you ever wonder why ice cubes floats when mixed with water? or when oil stays at the top of the water instead of mixing together? This goes back to 250 B.C when a Greek mathematician named Archimedes discovered density. Density explains the correlation of mass and volume and also when the object is supposed to rise, sink, or...

Sound: A Basic Introduction What is Sound? Sound can be described as variations in density and pressure that expand in an elastic medium which could be a gas, liquid or solid body. The precondition for variations in pressure to be defined as sound is furthermore that in addition to the source of the sound and the transmitting medium, there should...

Abstract – Active street lighting has emerged as an essential factor in strategies for a resource-efficient economy and realization of sustainable growth. In the outdoor area, lights represent approximately 40 % of the total energy consumption at night and have much energy saving potential. If passers-by or vehicles, summarized as traffic elements, are not located near street lamps, it is...

Abstract Our theoretical interpretation shows that the electron density is condensed at 150°orientation and perhaps the reason for the high mobility of electron in graphene. To determine the above result, the constructed monolayer of graphene contains 40 carbon atoms with 48 bonds in between them and 16 hexagonal polyhedra and the bilayer of graphene has 80 atoms with 96 bonds...

Abstract The main aim of the project is to design a circuit which would allow the detection of light by using a photodiode and to critically assess in details how a light sensing circuit using a photodiode works to obtain a desired output. This is achieved by using a transistor Darlington pair, four resistors (2*330, 1k, 4.7k), one LED and...

Abstract Polymers represent a good alternative option for current metallic heat exchangers. That is due to their low weight ,cost, and volumetric-thermal-capacity. Polymers also considered as stable anti-corrosive material. Furthermore, fouling is less likely to stick on polymer surface compared to metals. However, polymers thermal conductivity is way less that metals (more than 100 times). Several researches in the literature...

Introduction What is the speed of light and what affects? This question has been asked for hundreds of years and the answer is simple. The speed of light is approximately 299,792,458 m/s (Las Cumbres Observatory, 2019). This answers the first part of the question, but what about the second part? What affects the speed of light? The purpose of this...

Abstract When a body is in a state of motion, the total momentum is maintained, such that the product of mass and the velocity vector, until that moment when an external force is applied to it. This law is called the conservation of linear momentum, this principle somewhat corroborates the conservation of energy principle which states that energy is neither...
