The Noble Gas neon is one of the most inert elements known. Finding interesting facts about an element that does not do very much is difficult but I’ll try. Starting with the elements basic properties, its atomic weight is 20.1797 and its density...
Crystal growing made simple
By: A. C. Bowie
Growing crystals is easy, fun, and, a lot of times, edible and pretty to look at. It’s also a simple way to introduce younger kids to some basic elements of chemistry. It allows the opportunity to practice skills like careful measuring and the use...
Why and how absolute zero is -273.15 Celsius
By: Brian Dodson
What a strange notion – that there is a temperature below which it does not make sense to talk about temperature. Why can a body not have lower and lower temperature, and what sets the temperature we call ‘absolute zero’? This is a story...
Calabi-Yau spaces and their affect on reality
By: Brian Dodson
Calabi-Yau spaces have no effect on reality. However, they may shed some light on the traditional desire of humans to understand reality. Calabi-Yau spaces are mathematical constructs which seem to have significant importance to superstring theory, which is one of the currently popular theoretical models...
Crystal growing made simple
By: Molly Froerer
Growing a homemade crystal is a fun, simple science project that just about anybody can do! It requires some simple materials that are usually found at home, some patience, and a few days. The first step is to assemble the necessary materials. You will need...
Time Travel might Work
By: Brian Dodson
Is time travel theoretically feasible? In a trivial sense it is clear that time travel is possible – all of us are currently travelling into the future at a rate of one day per day. The real question here is can we change the rate...

In addition to the planets in our solar system, and the moons which orbit them, a vast number of smaller objects are known to exist. Thousands of comets have been discovered, and the number of asteroids is in the millions. What are these astronomical bodies...
Has science been ignoring the dynamics of the earth/moon relationship?

Author’s note: All credited material herein is in the public domain. A sincere attempt has been made to represent it accurately while integrating it into the overall theme. All uncredited work is from my own experiences as a graduate engineer and night college physics...
The difference between stars and planets
By: David Cardoso
The massive cloud of gas and dust that formed our solar system coalesced over hundreds of millions of years. The majority of matter was attracted towards the center thanks to gravity. This matter (mostly hydrogen and helium) gathered and eventually formed the sun. All the...

Nitrogen makes up 78.1% of Earth’s atmosphere. Daniel Rutherford discovered this colorless, odorless and tasteless gas in 1772. After removing both oxygen and carbon dioxide from air, Rutherford found the remaining gas supported neither life nor fire. Its name comes from the Greek...
