Extremely Important Everyday Life
484 wordsMomentum has an integral part in the field of physics. However, many people do not know the importance of momentum in everyday life or even recognize it. The truth is that we use momentum in just about every activity that involves motion. When we drive a car we use the principles of momentum to realize how much cushion space we need or how much stopping distance is needed when going a certain speed. Momentum is also extremely important when trying to understand collisions. Collisions occur every...

Back To Earth Solar Wind
1,313 wordsn this ERA of tight space budgets and infrequent deep-space missions, solar system researchers have pushed to squeeze more science from existing interplanetary spacecraft. By drastically altering their orbital paths using gravity-assisted maneuvers combined with relatively brief rocket firings, veteran probes can be sent on productive extended missions. This technique was successfully employed by the International Sun-Earth Explorer 3 (ISSE 3) spacecraft to accomplish two important space firsts:...

Human Nature Collective Memory
1,209 wordster>Sam Vaknin's Psychology, Philosophy, Economics and Foreign Affairs Web Sites Many futurologists - professional (Toffler) and less so (Naisbitt) - tried their hand at predicting the future. They proved quite successful at predicting major trends but not as lucky in delineating their details. This is because, inevitably, every futurologist has to resort to crude tools such as extrapolation. The modern day versions of biblical prophets are much better informed - a...

Run The Investigation Tiny Particles Oswald
533 wordsBefore we started the section on John F. Kennedy in our class I would have said that Lee Harvey Oswald assassinated him without a question in my mind. After reviewing videos on this subject in class I am now not so sure. Was there really a conspiracy to kill Kennedy or as a nation do we over analyze something that was an open and shut case? After reviewing the information in class I do not think Oswald was the lone assassin. I do not even think that Oswald was the assassin. The most convincing e...

Risk Of Developing Lung Cancer
987 wordsRadiological Determinant of Water Asbestos is a general name applied to a cluster of silicate minerals consisting of thin, divisible fibers in a parallel arrangement. Asbestos was found in water and appears to be dangerous to health. Different criteria are used to recognize asbestos fibers, depending on the context. In general, the Occupational Safety and Health Administration (OSHA) regulate as fibers those particles of the regulated mineral classes longer than 5 m in length. Asbestos fibers do...

Quantum Theory Catch 22
1,464 wordsThrough religion, philosophy, science, art, and mathematics, humans quest for an Absolute. They seek to find a still point where conflict cannot burgeon and principles may converge to an essential Truth. However, in Catch- 22 Joseph Heller suggests the unsettling idea that Life holds no pervasive absolute because in actuality Life is the continual clash of absolutes. Through the main character Yossarian, one is able to understand how the individual creates a world applicable only to himself; how...

Chemical Reactions Three Types
890 wordsChemical Chemical Reactions CHEMICAL REACTIONS Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named George Ernst Stahl was the first to speak of chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the ai...

Three Phases Law States
528 wordsSolids, liquids, and gases are the three main, or fundamental phases of matter. Each one has a different density and a different level of stability. What determines the stability of each phase is the bond between its atoms. The tighter the bond between its atoms the more stable that phase of matter is. Solids are the most stable form of matter, followed by liquids, and then gases. Solids have a definite shape and do not take the shape of their container. Liquids do not have any definite shape an...

Negatively Charged Positively Charged
571 wordsFusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei m...

Rotation Period Solar System
339 wordsMars is the fourth furthest away from the sun and is recognized by its reddish color. Mars is also very much like the Earth. More than any other planet in the solar system, Mars has characteristics that make it an Earth-like world (Grolier, 1992). One thing that is very similar to Earth is the rotation period. Mars rotation period is only thirty seven minutes longer than the Earths. This would explain why Mars has significant seasonal changes just as Earth does. It is believed that the Planets 5...

Nerve Endings Sound Waves
402 wordsWaves Sound Waves Sound Waves Waves are disturbances that travel through a space while changing its matter. A sound wave is what allows us to hear sounds. It is created by vibrations, which are made by the movement of matter. Sound waves must travel through a solid, a liquid, or a gas. The more tight the particles, the faster the wave will travel. This would mean that a sound wave travels fastest through solids and slowest through gases. The speed that it travels through a liquid would come some...
