Articles in Home | Reference & Education | Science Sort By: Title|Newest|Oldest A different approach to the alien theory  By : narenverma There has always been a clash in what we see and what we believe. Life is all about how we perceive it. Some consider it beautiful, some consider it to be struggle and some perceive it as a school of learning. There has been and there always will be a difference in our perceptions. What changes the facts are how we perceive them. Playing with the periodic table of elements  By : Anne Tide All the Science fair projects should be focused on the continuous change that is to be observed in the present properties of the elements. If you are highly interested in developing your own chemistry projects, you will have to pay attention to the current trends that affect the table of elements. These trends can also be understood by using the electron configurations that are available on every table of elements. These electrons are to be analyzed because they tend to lose or even gain various valences in order to obtain the final and stable octet formation that can be demonstrated through the science project. In addition to this constant activity, one may also observe other trends that may be demonstrated through the chemistry projects; for instance, the electrons are likely to be added by moving from the left to the right across a certain period. Talcum Myth  By : Tarkesh Botadra Talc (derived from the Persian via Arabic talq) is a mineral composed of hydrated magnesium silicate with the chemical formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. In loose form, it is the widely used substance known as talcum powder. Huntsville, Alabama's Space Camp  By : Robert Balwinder Huntsville, Alabama is the site of one of the most fervent of kids’ dreams: Space Camp. NASA sponsors a space camp in Alabama to help kids experience what it is like to be an astronaut. Most programs last one week, and they are also offered in conjunction with other community programs, such as 4-H. Attendance at Space Camp can comprise some of the most meaningful and interesting experiences of a child’s life. Theoretical concept of Hail  By : Pacific Disaster Precipitation is one form of hail. Hail in other sense means falling of balls or irregular lumps of ice (hailstones), 5 mm-50 mm in diameter on average, with much larger reported from severe thunderstorms. Thunderstorms always produced by cumulonimbus. small hailstones are >5 mm in diameter. They are layered and can be irregular and clumped together Introduction to Tsunami and its preventions  By : Pacific Disaster when a body of water, such as an ocean is rapidly displaced on a massive scale then we call it tsunami. It Is a series of waves. The effects of a tsunami can range from unnoticeable to devastating. There are various reasons behind the tsunami Information about the floods  By : Pacific Disaster A flood is an overflow of water, an expanse of water submerging land, a deluge. Floods are most commonly widespread of all natural disasters. They are also one of the most dangerous disasters as they carry enough power to change the shape of land on Earth. All about Tropical Cyclone  By : Pacific Disaster A tropical cyclone evolves when the storm system fueled by the heat released when moist air rises and the water vapor in it condenses. The earth's rotation also imparts an acceleration. Causes and remedies of Earthquakes  By : Pacific Disaster An Earthquake is a sudden movement of the ground that releases the elastic energy stored within the rocks, creating destructive seismic waves. The word "seismic" comes from the Greek word "seismos" meaning an earthquake, . These quakes are not isolated events Alligators! Nature's perfect ambush predator.  By : bocasteve This article describes the unique hunting technique of the American alligator, displaying why they are nature's best survivors. Global warming issues are in your hands  By : David Yuri There has been a lot of talk on the subject of global warming. Specialists believe that human activities in the past 50 years have given a negative boost to climate change. Cryptozoology - The evidence of creatures whose existence is uncertain  By : Robert W. Benjamin Whether it's bigfoot, mothman or other unknown creatures, science may always refuse them no matter what proof is found Star Formation  By : Mar Star formation is the process by which hydrogen & helium in molecular clouds change into the ball of plasma we call a star. Galaxies  By : Mar A galaxy is a gravitationally bound system of stars, interstellar gas and dust, plasma, and (possibly) unseen dark matter. Typical galaxies contain 10 million to one trillion (107 to 1012) stars, all orbiting a common center of gravity. In addition to single stars and a tenuous interstellar medium, most galaxies contain a large number of multiple star systems and star clusters as well as various types of nebulae. Solar System  By : Mar The solar system comprises the Earth's Sun and the retinue of celestial objects gravitationally bound to it. Traditionally, this is said to consist of the Sun, nine planets and their 158 currently known moons; however, a large number of other objects, including asteroids, meteoroids, planetoids, comets, and interplanetary dust orbit the Sun as well. Astronomers are debating the classification of a potential tenth planet and other trans-Neptunian objects. Planets  By : Mar A planet is generally considered to be a relatively large mass of accreted matter in orbit around a star. A mass that becomes massive enough to undergo nuclear reactions is considered a star, not a planet. The name comes from the Greek term πλανήτης, planētēs, meaning "wanderer", as ancient astronomers noted how certain lights moved across the sky in relation to the other stars. Based on historical consensus, the International Astronomical Union (IAU) lists nine planets in our solar system. Cosmic Dust  By : Mar Cosmic Dust refers to particles in space which are assemblages of a few molecules to tenth-millimeter-sized grains. Cosmic dust can be further distinguished by its astronomical location; for example: interplanetary dust, interstellar dust, comet dust, circumplanetary dust. This article covers bulk and radiative properties of cosmic dust, the dust particles' origins, end-fates, and specific locations in space. Comets  By : Mar A comet is a small body in the solar system that orbits the Sun and (at least occasionally) exhibits a coma (or atmosphere) and/or a tail — both due primarily to the effects of solar radiation upon the comet's nucleus, which itself is a minor planet composed of rock, dust, and ices. Due to their origins in the outer solar system and their propensity to be highly affected (or perturbed) by relatively close approaches to the major planets, comets' orbits are constantly changing. Star Constellations  By : Mar A constellation is any one of the 88 areas into which the sky - or the celestial sphere - is divided. The term is also often used less formally to denote a group of stars visibly related to each other in a particular configuration or pattern. Stars  By : Mar A star is a massive body of plasma in outer space that is currently producing or has produced energy through nuclear fusion. The most familiar and closest star to the Earth is the Sun. Unlike a planet, from which most light is reflected, a star emits light because of its intense heat. Scientifically, stars are defined as self-gravitating spheres of plasma in hydrostatic equilibrium, which generate their own energy through the process of nuclear fusion. Stellar astronomy is the study of stars. Turtles  By : Mar Turtles are reptiles of the order Testudines (all living turtles belong to the crown group Chelonia), most of whose body is shielded by a special bony or cartilagenous shell developed from their ribs. The order of Testudines includes both extant (living) and extinct species, the earliest turtles being known from the early Triassic Period, making them one of the oldest reptile groups, and a much more ancient group than the lizards and snakes. How to use solar panels ?  By : DORA WYSOCKI Raising price of oil, gas and other commodities brings on the surface the question about utilizing other resources of energy like of solar energy.

The Invisible Ether and Michelson Morley  By : MStrauss Modern scientists adopted the ancient concept of the ether to explain the fundamental nature of the universe. Einstein allegedly dethroned the ether concept with his space time continuum. In spite of this, we might have to revisit the ether concept. Galactic Mystery - Matter - On the Dark Side  By : MStrauss Scientific inquiry can be described as a sequence of observations leading to a hypothesis which must be tested by experimentation. The results either validate or invalidate the hypothesis which was under test. Unfortunately, the interpretation of the data sometimes does not elucidate some new truth but rather eclipses our thoughts into a new era of ignorance. Using a home DNA test kit  By : Peter Vine A home DNA test kit is exclusively used in the sampling stage of a home based DNA paternity test. The key component in the kit is usually a pair of serrated cotton swabs, and some DNA free sample tubes. These two components allow the obtaining of the source material which will ultimately be used to determine the biological relationship of a child to the putative parents. Is The Big Bang A Cosmic Blunder?  By : Josh Greenberger For years scientists have been telling us how the universe began. Do we really know? Or do we need another six billions years to figure it out? Elemental Chemistry for Everyday Needs  By : Matt Bishop If chemistry was not your strong suit in school, maybe you could use the help of a convenient refresher now and then. If so, you can easily find easy-to-read online Websites listing chemistry’s periodic table.

DNA Paternity Testing – 5 key questions you should ask your DNA testing provider.  By : Peter Vine DNA paternity testing in its purest form is the application of DNA technology to provide information about the parentage of an individual (usually a child). The mother of the child is rarely disputed, and most of the time DNA testing is requested to inform the likely father of a child. The Solar System: Do Scientists Really Know How It Formed?  By : Josh Greenberger The vast differences between the planets do not seem to support the accepted scientific theories of their formation. Sodium Vapour Lamp  By : dasan Sodium Vapour Lamp consists of a discharge tube made from a heat resistant glass, containing a small amount of metallic sodium, neon gas and two electrodes. Big Bang Booming - Back To The Future  By : Michael Strauss - Theoretical cosmologists spend much of their time perfecting what is now known as the 'Big Bang' theory. This concept originates from ideas percolating in the minds of scientists, theologians and astronomers down through the ages. However, much of what they consider as proof for the 'Big Bang' is dependent upon uncontrolled experimentation that is molded to meet their expectations. Then God said, "Let there be light," and there was light. This ancient description of the cr... The Benefits Of Agricultural Biotechnology  By : George Royal - Agricultural biotechnology is any technique in which living organisms, or parts of organisms are altered to make or modify agricultural products, to improve crops, or develop microbes for specific uses in agricultural processes. Simply put, when the tools of biotechnology are applied to agriculture, it is termed as “agricultural biotechnology”. Genetic engineering is also a part of agricultural biotechnology in today’s world. It is now possible to carry out genetic manipulati... Neanderthal Species Distinct From Humans  By : Greg Neyman - For many years young earth ministries have claimed that Neanderthals were modern humans. However, new evidence shows that they should in fact be a separate species, which died out, and did not contribute to the gene pool of present-day humanity. In a story reported in late January 2004, scientists did a detailed computer analysis of human and Neanderthal skulls, comparing the variations with the variations of sub-species of apes. (Footnote 1) The computer analysis showed t... Increasing Applications of Micro Bubbles  By : cyberryo Micro bubbles are miniature gas bubbles of less than 50 microns diameter in water. The micro bubbles, which mostly contain oxygen or air, can remain suspended in the water for an extended period. Gradually, the gas within the micro bubbles dissolves into the water and the bubbles disappear. These bubbles are generated by various types of aerators now available in the market. Total Eclipse Of The Sun Expected In March  By : Mr Hanna - A total solar eclipse, one of the earth's most unique phenomena is when the Moon passes between the Earth and the Sun, its shadow hitting the Earth and blocking out the Sun. If you're lucky enough to be in the path taken by the centre of that shadow, the Moon will align itself exactly with the sun, blocking it entirely and you'll see a total eclipse. Outside of the path of totality, although a staggering 95% of the Sun is still obscured, the effect of the eclipse is not n... Space Exploration - What's Out There?  By : Paul Callis - The first Space Exploration started in 1957 with the launch of the first artificial satellite, Sputnik 1, sent into space by the Soviets. Since ancient times people have dreamed of leaving their home planet and exploring other worlds not known to man. Every era through out history has had a belief as to what the "heavens" are made form. The Greeks believed that the stars and space were made of a material called "Quitenses", and other culture once thought that the stars were m... "WE DON'T know what we are talking about" - Nobel Laureate David Gross  By : MStrauss Science has reached an enormous impasse. From biology to physics, astronomy to genetics, the scientific community is reaching the limits of understanding which often presage a complete rethinking of long-accepted theories. So characteristic of this new apex of modern arrogance is the inability to comprehend the obvious in physics: That we don't know what we are talking about. Why Does The Tool Bit Break Easily In Micro Milling?  By : cyberryo While micro milling has been successfully applied in manufacturing bio-medical components, embossing dies and micro encoders, the breakage of the tool bit has been identified by many users as a teething problem. How To Machine Magnesium?  By : cyberryo The main concern in machining magnesium alloy is the danger of fire ignition when dry cutting. Fire may occur when the melting point of the alloy (400-600 degrees Celsius) is exceeded during machining. How To Make Lighter and Thinner Magnesium Components?  By : cyberryo The most common methods to produce magnesium parts are die casting and thixomolding processes. However, these runner and gating processes provide a low material yield of only 30% for thin-wall casting and can only produce thin walls of between 0.7mm to 1.2mm. How To Use Diamond Tool To Cut Steel In Micro Machining?  By : cyberryo If a diamond tool were to be used to cut steel, the diamond tool will face severe tool wear. While diamond only softens at 1350 degree Celsius and melts at 3027 degree Celsius, and is also the hardest material in the world, it has a weakness. Different Branches Of Chemistry  By : John Mclain Chemistry is generally divided into two broad branches: organic chemistry and inorganic chemistry. Other types of chemistry include physical chemistry, biochemistry, and analytical chemistry, with each field branching off into several specific subfields. Here’s a brief description of the most common branches of chemistry. Organic Chemistry Organic Chemistry has to do with the study of compounds that contain carbon (and sometimes hydrogen). Even though carbon is only the... e=mc2 Is Wrong - Einstein's Special Relativity Fundamentally Flawed  By : Michael Strauss In 1905, Albert Einstein published 'On the Electrodynamics of Moving Bodies' now known as Special Relativity; this theory revolutionized geometry, math, physics, science and the classical perspective of the universe as understood since Newton's time. However, were there intrinsic errors in this theory? USA (Wire) December 12, 2005 -- Is Albert Einstein's Special Relativity incompatible with the very equations upon which science's greatest theory is built? New observati... Organic Chemistry 101  By : John Mclain Organic chemistry is a branch and specific discipline of chemistry. Organic chemistry deals specifically with the properties, structure, and composition of organic compounds. Organic compounds, by definition, are compounds that contain carbon and hydrogen atoms. It is generally agreed that the science of organic chemistry began in 1828. It is then that Friedrich Woehler accidentally evaporated an aqueous solution and came up with the organic compound called urea. Although... Weird Science – The Inner Workings Of The National Science Foundation  By : Dave Klein The National Science Foundation is an independent government agency in the United States. The National Science Foundation is responsible for providing support to basic science research, which is primarily accomplished through research funding. The National Science Foundation mostly provides research funding in the form of grants. These grants are most often given in the form of individual grants to graduate students and professors. In fact, with an annual budget of approx... The Role of Private Enterprise in Putting Man into Space  By : Thomas Sullivan Has NASA, the monolithic space agency, failed in it's quest to put man out into the cosmos? Will profit coupled with man's need to explore be the driving engine which sends man into space? In this article we will examine these questions. We will discuss the justification for the active role of private enterprise in sending out true explorers into the cosmos. We will also examine the developing trends in space exploration. A Close-Up Look At Microscopes  By : Logan Pallas The microscope is an important educational tool used in scientific research and education. It is used to produce a larger image of an object for projects ranging from medical discoveries to important educational training in schools across the nation. Microscopes use technology to allow humans to view objects as they could never be seen with the naked eye alone. A conventional microscope was first developed during the last part of the 16th century, which lead the world of ... Understanding Telemetry  By : Leon Chaddock Will telemetry work for your industry? This is an amazing way of measuring. You will find that it is used commonly as a means of measuring things at a distance. Normally, it is used by scientists and engineers who need to measure things that are nowhere near them. The uses of telemetry are varied and many. But, you can see its use everyday. For example, many scientists use it to measure the weather conditions. By sending weather balloons high into the air, they can measur... Giant Squid Finally Captured On Film  By : The Iconoclast On 27 September 2005, the greatest zoological discovery of the century was announced. For the first time ever, a live giant squid was caught on film. The Animal The giant squid (Architeuthis) has been known to humans since ancient times. Giant squid were regular features in many Norwegian tales (where, many believe, it inspired the creature known as the Kraken). The first substantiated report of a real giant squid, was in 1873. The animal was reported to have been att...	Authors Sign Up for a free account. Submit your articles. Publishers Category RSS feeds.
