Why objects float
By: Grant Mckenzie
The primary reason objects float is buoyancy, an effect discovered by Archimedes of Syracuse. Basically, this principle states an object will float if it weighs the same as the amount of water it displaces. In other words, a 20 lb. object will float if it...
Carbon dating: Explaining the physics and methods
By: Adam Feneley
Radio-Carbon Dating Explained:Carbon dating is a radiometric dating method, which uses Carbon -14 (a naturally occurring radioactive isotope of carbon). This method can be used to date carbonaceous materials (substances which are rich in carbon), by using applied physics theory such as half-life.The technique...
An overview about the chemical element Hafnium
By: Mayflor Markusic
Two dozen years before halfnium was discovered and identified, its existence was already predicted by Dmitri Mendeleev. The same Russian scientist also predicted that this element will have properties that are similar to another metallic element, the zirconium. In the early 1900s, Niels Bohr, a...
NASA: One Small Step... Backwards
By: Wayne Whitt
We still struggle to reach space.Each space mission reminds us that we cannot assume that it is easy to get into space.This week's mission to launch an Orbital Taurus XL rocket from Vandenberg Air Force Base carrying the NASA Orbiting Carbon Observatory (OCO)...

Nuclear fusion is, to put it simply, smashing very light atoms together to make heavier ones. In the process they release a large amount of energy which we can harness for electricity.In principle this sounds straightforward, but in practice the technological hurdles we have...

Gold jewelry was buried along with the mummified bodies of Egyptian pharaohs. Johnny Depp had to wear gold caps on his teeth for his role in the Pirates of the Caribbean. From tombs to teeth, gold can be found. People would sell gold, hoard gold...
The physics of automobile accidents
By: Kevin Olivier
(Before reading this article, let it be noted that physics is an extremely complex subject to teach and grasp. Because of the many complexities involved every day events, I will be writing this article with the impression that the reader knows absolutely nothing on the...

There are many things to consider when thinking of a science project for high school. Some of the major things you need to consider is if the project is interesting. Boring projects do not attract much attention, and you will most likely do better at...
The scoop on the uncertainty principle
By: Joe Mccane
Quoted from one of the greatest scientists of the 20th century, Albert Einstein, "... god does not play dice." He gave this response when Werner Heisenberg proposed the uncertainty principle, Einstein said that statement thinking the natural world does not go by probabilities. Heisenberg...

Iron, one of the transition metals, is a common and well known element. Most readers will be familiar with it as a dull gray metal, great for making nails, horseshoes, and skillets. It is one of the stronger metals, and has a higher melting temperature...
