Intermediate physics: Explaining capacitors and capacitance
By: Jacob Stanley
A capacitor is simply a circuit element used for storing charge. It is generally constructed of two closely spaced metal plates. When we apply a voltage across the plates, a positive charge will develop on one plate, a negative charge on the other. When that...

FUNDAMENTAL MECHANICS" "I have deep faith that the principle of the universe will be beautiful and simple". - Albert Einstein (1879-1955) In the early 1970's, Quark Theory was relatively well established but, no quarks or direct evidence of any had been found. A film titled...
The real meaning of E=MC2
By: R K vanderHoek
This simple equation is the most profound scientific statement about the universe we live in that you will ever learn. With it Einstein takes all existence and reduces it to one thing, energy-mass which composes all matter. Energy-mass is transmutable at a ratio defined by...

Is time travel possible? Well, we are all traveling into the future every moment of every day, however, traveling backward in time is not physically possible. Simply stated; once something has occurred in a particular point in space and time, it cannot be revisited for...
How airplanes fly
By: Mark Bukovich
The sight of a sixty thousand pound hunk of metal rising into the air and jetting off over the horizon is indeed inspiring, almost magical. It is even more impressive to see a giant Boeing 747 take off or land in a high crosswind strafing...
Why and how absolute zero is -273.15 Celsius
By: Lime violet icosahedron
Like all of my predecessors have mentioned, I feel a need to point out that absolute zero is in fact -273.15 degrees Celsius, -459.67 degrees Fahrenheit, or zero degrees Kelvin. It is the theoretical temperature which matter ceases to move and all energy...
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...
By: Morgan Carlson
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...
