The issues around nuclear power
By: Rick Badman
We have problems with nuclear energy because we generally choose not to correct them. Weaning ourselves off of nuclear energy would be like weaning ourselves off of the future. The power sources anti-nuclear people advocate are either older than nuclear energy or not as...

Most of us will be familiar with rockets and jets. When we watch a Space Shuttle launch or an Air Force fighter take off we are seeing both types of engine in action. They certainly look similar - with all that heat and noise...
The best sources of energy for the future
By: Joseph Malek
It is quite clear to me that the best energy source for the future is the radiant energy that reaches the Earth from the Sun. By using such energy there are two primary ways to produce electricity. The concentration of the rays of our Sun...
Do time machines really exist?
By: Jishi Santos
As a teacher I had the class make a time machine after they had suggested the idea. Oh what fun they must have thought and so did I. So we had a class discussions to how we would actually do this and convey the...

A biography: Nikola Tesla Nikola Tesla was born to Milutin Tesla, a Serbian Orthodox Priest, and Djuka Mandic at midnight on July 10, 1856, in Smiljan, a village in the province of Lika, Croatia. Tesla completed his elementary education in Croatia and continued his education...
The best sources of energy for the future
By: Rick Badman
For most of my life I have considered nuclear energy the best source of energy available. I still do. It is relatively compact, powerful, and abundant, to some extent. Once we learn how to use nuclear waste to generate electricity, we may have an...
Introduction to vectors in physics
By: Chandra Wijaya
We classify quantities into two major groups in Physics. They are vector quantities and scalar quantities. What is the difference? The first ones have both magnitude and direction. The later have only magnitude. Magnitude is the number mentioned for a measure. The examples for a...

Black holes, wormholes and time travel. If a person was to look up the three most intriguing words in all of physics, these would be it. What is most interesting, and satisfying, is that there is an inherent connection behind all these three phenomena. And...
Circular motion physics concepts
By: Chandra Wijaya
An object moves around a circle is called in circular motion. Sometimes the speed of the object is constant. This motion is called uniform circular motion. There are several important terms in circular motion. I will discuss them subsequently. The first is the frequency. Suppose...

As the worlds energy demand increases the amount of fossil fuels left for use to extract diminishes and climate change becomes more and more evident. We all need to do something to help the environment and make coal and gas last longer. Everyone should look...
