Stoichiometry: Basics and calculations
By: Lime Red Tetrahedron
Stoichiometry: Basics and CalculationsStoichiometry can seem daunting to the beginning chemistry student, but is perhaps one of the most basic and simple concepts in any chemistry course. Stoichiometry refers to the fixed ratios in which substances react, and the analysis that is enabled through the...
Moon Landings Apollo Conspiracy Theory
By: W.H. Garcia
The Apollo landings on the moon have left an indelible mark on modern human history. Attempts to deny them are often borne out of sheer ignorance of hard scientific facts. It is no doubt a grave insult to the dedication and time put in by...
Echoes: Causes of echoes
By: Jessica Oakes
Being a sociology major in college I often am a people watcher and find these odd human behaviors interesting. I was listening to the radio the other day and a commercial came on that had an echo on it. I don't remember what it was...
The best way to filter data
By: Mark Majors
When one is presented with any type of data, the use of filtering is a common practice for turning their data into information. Data itself is simply a collection of letters and numbers, but when data is manipulated, or in this case filtered, it can...
Introduction to vectors in physics
By: Lime Red Tetrahedron
Introduction to Vectors in PhysicsVectors are a simple approach to solving many classical problems, including dynamics, ballistics, and problems dealing with gravitation. In fact, vectors are so integral to physics that most courses begin with instruction on their use. Thus it is essential that any...

What is Time? We live by it in set increments that move our society, larger quantities help document the events in the past, and the uncertain amounts aid us in determining what's to come. But what it is boggles most who try to understand it...
More math equations
By: Mishra Planeswalker
When studying kinematics (the study of motion) it is important to know a few essential mathematical equations. These equations can be further developed by the use of variable substitution, as well as other mathematical operations. When taking advanced physics courses, calculus is a recommended tool...

"The only reason for time is so that everything doesn't happen at once." EinsteinTime is an increment of measure devised by human beings to describe a rate of change (a ratio of motion described by one object in relationship to another). Time is not...
Does the Large Hadron Collider have the Potential to Destroy Earth
By: Chris Webber
Does the Large Hadron Collider have the potential to unlock the secrets of the universe? Absolutely! Will it bring us fantastic new technologies and revolutionise science? Definitely! Will it destroy the Earth? No way.The thing is, part of the problem is that what actually...
Exploring the ozone layer
By: Alex Thompson - 495703
The abundance of ozone in a column of air having a diameter of one centimeter varies seasonally and with latitude. In the equatorial region of the Earth, the ozone content of the atmosphere is about 250 Dobson units (DU), where:1 DU = 2.69 x...
