Aerodynamics

Our Air is something we take for granted as opposed to food or water we don’t really contemplate much about it. Similar to the way we breathe it’s just a part of our life whether we consciously think about it or not. Comparable to our subconscious breathing is the autonomous effects polluted air can have on just about every aspect of the world. Its indisputable to say all of you know in our lifetime, environmental concerns revolving around our expenditure of fossil fuels and the effects it has…

The fish family Exocoetidae can be found in the order Beloniformes and class Actinopterygii. One of the common name of the family Exocoetidae is flying fish. Exocoetidae contain 64 species and is group into seven genera. The seven genera name are Cheilopogon, Cypselurus, Exocoetus, Fodiator, Hirundichthys, Parexocoetus, and Prognichthys. The reason Exocoetidae get the name flying fish is its ability to glide through the air. The oldest fossil that a person has found of Exocoetidae is…

In the United States for every car there are 1.3 people.(Tencer 1) Just a fraction of those cars are electric and don’t pollute the air like gas cars do. Tesla, How will electric cars revolutionize the transportation industry. Tesla Motors first started in June of 2003. Martin Eberhard and Marc Tarpenning were the ones who started the business and played a big role in the company before Elon Musk stepped in. They financed the company until the Series A round of Funding and soon after Elon…

NEWTON’S LAWS OF MOTION Water rockets have used many times to test and explore the fundamental principles of physics. To understand what determines how far a water rocket may fly or how a rocket may even lift off, it is important to delve into the deeper detail; the forces acting in play. Newtons Laws govern the central principles regarding the physical forces which may act on a particular object in space. There are three laws which were developed by Sir Isaac Newton in 1686, when he published…

The first powered airplane flew only 12 seconds and covered 120 feet in 1903 piloted by Orville Wright. (Eyewitness, 2003) The 20th century saw the greatest achievements for aviation as each decade progressed with innovation and advancement. In this day and age, the aviation industry provides an important contribution to economic and social benefits worldwide. However, aviation would certainly not be how it is today without the effect of warfare during the 20th century on the development of…

Introduction Drosophila melanogaster can be considered model organisms for the study of genetics. Some characteristics that contribute to this status are their quick lifecycles, large amount of offspring, and the presence of only four chromosomes. Drosophila melanogaster contain bristles on the thorax, head, legs, and abdomen. These bristles are used as a sensory mechanism, allowing fruit flies to detect their surroundings as they fly and walk around their environment (Yehuda, 2011). The rate…

In the last 35 years, 789 out of 833 people have returned to Earth on a NASA Shuttle. However, seven of the casualties were from a failed reentry of the atmosphere which occurred on February 1st, 2003 when the STS-107 Columbia burnt up and disintegrated during reentry. In this log, one will learn how a space shuttle is designed and how the trajectory a ship takes to reenter the Earth’s atmosphere safely. Space is everything, discovered known places, and also the dangerous unknown. However, when…

Egyptians developed one of the first decimal system. The Egyptians were also responsible for developing geometry for purposes of construction, advances in mathematics and astronomy, improvements in irrigation and agriculture, ship building and aerodynamics the wheel and…

Nowadays, nearly every student smears a highlighter all around their notes, and calls it "studying," but in reality these kind of methods do not work well; this phenomenon is explained the book Make it Stick. The cognitive scientists, Peter C. Brown, Henry L. Roediger III, and Mark A. McDaniel, explain why people are attracted to ineffective strategies for learning and teaching and how the concept of learning is misunderstood by most students and teachers as well, which creates difficulties in…

As a body which was set to oversee development of the railway system, the Railway Investigation Office had the main function of carrying out studies, applying the results gotten from the studies and testing out the materials. In 1913, it became known as the Research Institute before it was restructured in 1942 as the Railway Technical Research Institute. The standards of the railway in Japan had fallen behind those of other railways around the world by 1945 (Seojima 5). This realization prompted…
