Archaeoastronomy 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.

There 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.

In 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.

Most 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.

Over 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.

A 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.

A 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.

Perhaps 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.

Science 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.

I did a Google search and came across your site. It was exactly what I was looking for and was elated to find such a broad range of articles. As I am launching a free magazine in a small town in Florida, I wanted to be as resourceful as possible while still being able to provide some content that is interesting and well written. Your site has all the variables in the mix. Excellent Site hitting all the notes in the scale sort of speak.
