Galileo Probe INTRODUCTION The Galileo Probe was an entry into the atmosphere which was carried out by the Galileo spacecraft to the heavenly body, Jupiter. The probe entered the hot spot and then returned to the earth with useful information of space. The probe was 747 lb. And it was built by Hughes Aircraft Company at the plant in California called El Segundo (Russell, 2012). It measured about 1.4 meters across. The probe was devised in a way that it could sustain high temperatures…

Introduction The Singapore Armed Forces (SAF) has come a long way since she was first established in 1965. The SAF became a conscript armed force in 1967 and started off with two infantry battalions and three Republic of Singapore Navy (RSN) ships (Mindef, 2017). The Republic of Singapore Airforce (RSAF) was formed in 1968 with eight aircrafts to train the pilots (Mindef, 2017). During the 1960s, the priority was to build the foundation for Singapore’s defence (Mindef, 2017). Today, as…

The topic I have chosen to discuss for research is the right to die, specifically as it relates to euthanasia. This topic of euthanasia is of high level interest to me due to the fact that their has been many controversies surrounding whether or not someone can make a personal decision to live or end their own lives. I know that euthanasia, is a request from a person with a sickness that has had their quality of life taken away, to end their lives with help. This request is also known as…

A water molecule is made of two hydrogen atoms and one oxygen atom. Oxygen and Hydrogen are gases but when combined form into a liquid compound; water. The hydrogen atoms make an angle of around 105 degrees with the oxygen atom. The oxygen atom dominates an end of the molecule while the hydrogen atoms dominate the other. The asymmetry of the water molecule causes the oxygen end to have a slight negative charge while the hydrogen end has a slightly positive charge. A molecule with both (-) and…

Magnetoencephalography (MEG) is a neuroimaging instrument that analyses the magnetic fields that are generated by electrical activity in the brain (post-synaptic action potentials). Magnetic fields are recorded by sensitive magnetometers, whereby the pick-up coil stimulates a current that can detect very weak magnetic signals, ‘superconducting quantum interference devices (SQUID’s) are usually used. Moreover, as SQUID’s can detect such subtle magnetic field changes this allows MEG to produce…

WHAT IS NMR SPECTROCOPY? By definition, NMR spectroscopy is a research technique that makes use of the fact that certain atomic nuclei exhibit magnetic property to determine their chemical and physical properties for various uses that we’ll discuss later. History of NMR Spectroscopy Year Individual Discovery 1921 Stern and Gerlach Basis of quantum theory is confirmed by carrying out atomic and molecular beam experiments 1925 Ulhenbeck & Goudsmith Discovered the concept of spinning…

Apollo 13 the “Successful Failure” How did the failure of Apollo 13 actually help NASA in some ways? This essay will show how and why the failure led to later success for NASA (National Aeronautics and Space Administration). Apollo 13 was an interesting exploration for many reasons: the astronauts in space, Apollo spacecraft, and the difficulties during the exploration. First of all, this paper will tell all about the astronauts, and the responsibilities they had on the mission. Secondly, the…

Since the dawn of man, humans have been awe struck when faced with the vast, gleaming night sky. We have wondered, dreamed, and raised questions as to what lies beyond the stars. However, one particular shimmering dot has invoked the imagination of stargazers time and time again. The red planet, Mars. For countless centuries our understanding of Mars has been significantly limited. Theories of what may rest on the planet’s surface were left unrequited until a handful of scientists and engineers…

Section A: Introduction OAO Gazprom is one of the largest companies in the world and is the largest extractor of natural gas. Gazprom is based in Russia in 1989 when the Soviet Ministry of Gas Industry converted into a corporation. Gazprom is a global energy company and majors in lines such as geological exploration, production, transportation, storage, processing and sales of gas, and many others. Gazprom also holds the world’s largest natural gas reserves where they hold 14 and 74 percent of…

History of the Theory of Atoms Before the age of modern technology, theories of the atom were still created. Most notably was Democritus who was thought of as being the start of modern science when he first came up with the idea of the atom. It was not until J.J. Thomson changed the way atoms were understood with the discovery of the electron. It was not soon after when Ernst Rutherford disproved Thomson’s model with his gold foil experiment. Finally, Niels Bohr built off Rutherford’s gold foil…
