Physics

The most common element in the Universe has more forms than you may realize...

We may be on the threshold of some serious answers to how physics is all connected. But first, we need to do some testing and find out our viable options.

While it may ultimately prove to be wrong, scientists know of several ways to test for string theory using many conventions of physics.

Ballistics is a branch of mechanics which deals with the motion of projectiles launched into the air or space. Solving these type of problems involves using Newton's equations of motion

Man has taken many inspirations for soaring the skies, but nature has held some secrets that we are only now uncovering...

Paper cranes and little boats are the easy parts of origami. Wait until you see the surprising connections it and kirigami have to physics!

The simple RC circuit is a basic system in electronics. This tutorial examines the transient analysis of the circuit as it charges and discharges, explaining the voltage and current waveforms and also covering the solution of the differential equations for the system.

Dark matter and dark energy are still huge mysteries in astrophysics. Alternate theories exist to help explain them.

The concept of emptiness in physics is enormous. There is mostly physical nothingness in the entire universe. Follow along with me as I explain this.

Carbon is a pretty amazing material that as you will see is offering some amazing changes to technology.

Water has some properties that can make it a good refrigerant. It also possesses some undesirable properties that makes its application as a refrigerant very challenging and inefficient to implement.

Students have an excellent chance of doing well on a physics exam if they work efficiently throughout the physics course and follow some tips for writing exams.

Another day, another quantum phenomena to explore.

Solid, liguid, gas, and plasma, right? Well...

Why does time only go forward? I discuss a theory I call "Time Gravity" that creates a force in only one direction.

A description of the historic oil drop experiment that was performed by Robert Millikan to determine the electrical charge of the electron. Included is a diagram of the apparatus used and a discussion of the forces acting on the oil droplets.
