Sun, 25 Sep 2011 00:00:00 -0400Archaeoastronomy is the study of how folks in the past accepted the phenomenon occurring in the sky, how they utilised the phenomenon and what part the sky played in the culture of these people. Archaeoastronomy can be said to be closely associated the historical astronomy. It is also related with the historic records of heavenly events which can often be used to answer astronomic Problems.
Sat, 24 Sep 2011 00:00:00 -0400There are lots of predictions depending on which on 21st December 2012 the world will end. This date is meant to mark the end of a cycle of the Mesoamerican long count calendar which is alleged to be just about a 5125 years old cycle. Some people interpret the import of this date differently and say this date will mark the beginning of some changes and transformations.
Fri, 23 Sep 2011 00:00:00 -0400In the sector of astronomy axial tilt is also known as obliquity. The axial tilt is generally accepted to be the angle between the rotational axis and the line vertical to the orbital plane of an object. Now Earth's axial tilt is 23.4. The orbital plane of Earth is commonly known as ecliptic plane and the there's a different name for Earth's axial tilt 'obliquity of the ecliptic'. This axis remains tilted in the same direction across the year.
Wed, 21 Sep 2011 00:00:00 -0400Most of the time, people turn on an electric gadget in their homes and do not think twice about the electricity that flows through wires. Neither do they think about what it takes to control that electricity. Control of the electric current is achieved by making use of power relays. To simplify, these relays are electronically operated switches. They help to control power circuits.
Mon, 19 Sep 2011 00:00:00 -0400The 1990s has seen the growth of high content screening and analysis technologies and these have been adopted in the field of drug discovery.

Tue, 30 Aug 2011 00:00:00 -0400Over 400 new science fair projects including some new wrinkles on some old favorites now available on line. You will probably find just the project you are looking for to present for your next school science fair. These projects are about generating electricity from potatoes and lemons, and also about growing fruit and veggies without water. There is a new project about testing magnets when they are at room temperature, as well as when they are cold and hot to determine if the magnetism is effected at different temperatures.
Mon, 29 Aug 2011 00:00:00 -0400A science fair project may reveal that almost anyone can write about almost anything quite easily. For many years I have taught students as well as professionals my methods of getting it down on paper, quickly and in good form. There are a few secrets involved in this unusual system, but I will share them with you. Standing in front of a group of wannabe writers, I asked them what the biggest problem was in their writing.
Mon, 29 Aug 2011 00:00:00 -0400A good idea for a science fair project is to find out what makes an airplane fly. We earthlings are really two dimensional animals. At an early age we learn how to ride a three wheel bicycle. We learn how to turn left or to turn right. After a while we get on roller skates, and here again we learn how to turn but whether on the bike or the skates, we never learn how to go up or down. You just cannot go up or down in our two dimensional worlds, not until we learn how to defy gravity.
Mon, 29 Aug 2011 00:00:00 -0400Perhaps a science fair project will help you to determine why a 14 year old girl who is only five feet tall and weighs but 100 pounds can hit a golf ball 250 yards, perhaps even as far as 300 yards. This is all the more alarming when a six foot man, 35 years old, 185 pounds, with 10 years of experience playing golf can only hit the ball 165 yards.
Sun, 28 Aug 2011 00:00:00 -0400Science fair projects on fine art is a virtually untapped area. Not too long ago, a Jackson Pollock painting sold for $140 million. This abstract expressionist work of art is said to be the highest price ever paid for any painting. When you consider that Picasso, and Chagall, and Degas and Rembrandt and so many other people of genius have thousands of works of art in galleries and private collections, and museums all over the world, why does a Jackson Pollock, nonrepresentational drip painting command such a sum of money? And just how did Jackson Pollock do his artwork? Great idea for a science fair project.
Sun, 28 Aug 2011 00:00:00 -0400Small size batteries with super power and longevity could revolutionize almost everything. Imagine owning and driving a car with a very small battery with enough power to drive for 50,000 miles before needing recharging. You would eliminate the need for gasoline, gasoline stations, fossil fuels, and all of the contamination caused by burning oil. You would change the health potential and longevity of the entire world by getting rid of pollution in the air and the sea. What great subject matter for cool and winning science fair projects for all grade levels.
Sun, 28 Aug 2011 00:00:00 -0400Make your imaginary dream come true with a trans-Atlantic sailing trip to the Caribbean Sea. The best place to depart from Europe to get ready to cross the Atlantic is Gibraltar. When you entered the Mediterranean Sea you had to convert your boat from United States outfitting to suit the very different needs of the Med. For one, the 120 volt electrical system compatible with all U.S. ports just won't work in the Med. Virtually every country has different sized electrical plugs and a 220 volt electrical system is necessary. You had to install a transformer to handle this difference when you arrived into the Med, but now you have to convert back to the 120 volt U.S. electrical standards.
Tue, 28 Jun 2011 00:00:00 -0400The intuitive inventions in the field of electro-magnetism have enabled the human race to perform once complex industrial operations with greater ease and safety.

Fri, 24 Jun 2011 00:00:00 -0400Well in that case first of all you will have to find out what forensic science is. It is a term used to describe a number of sciences which serve for answering questions of an issue being legal or illegal. The term has quite a long story. It actually comes from Latin forensic, which means "of or before the forum". The way criminal deeds were investigated in the times of Romans is not too different from the way they are now. In the court there are accused and accusing sides.
Wed, 08 Jun 2011 00:00:00 -0400When it comes to electronic circuits, it can be broadly divided into two categories.Analog and Digital electronics. Read to learn more about them. They are also known as linear circuits. Some of the most common analog appliances present in the market are radio receivers, transistor amplifiers, operational amplifiers, oscillator circuits and so on. All these circuits use some of the most basic electronic components like transistors, diodes, resistors, capacitors and so on. Analog circuit uses a continuous range of voltage as its operating mode.
