The Large Hadron Collider
The Large Hadron Collider is considered to be the largest and highest energy particle accelerator complex. Also more popularly known as the LHC, the Large Hadron Collider is located somewhere underneath the Franco-Swiss border in between the Alps and the Jura mountains near Geneva, Switzerland. The gigantic scientific instrument is intended to help aid physicists and scientists to study the smalle... [Read More]
New Material Developed That Can Make Objects Invisible
In the mission to find a means to render objects invisible, scientists have recently developed a concept for a new type of material that may someday make this possible. For the first time, researchers have been able to demonstrate that a new material can bend visible light the wrong way in three dimensional tests. The research has been based on cloaking technology based on microwave wavelength. Th... [Read More]
Hydrogen Economy
With the rapid rise of oil prices today, there might already be a need for the world to try out another type of fuel that would power up factories and plants as well as future vehicles. One of the alternative sources of fuel being eyed is hydrogen. When proven to be a successful alternative fuel, hydrogen may give rise to what is popularly known as the hydrogen economy. The hydrogen economy is sup... [Read More]
How Electricity Works
Electricity is what goes on whenever there is a presence and flow of electric charge. This could include lightning, static electricity, even electromagnetism. In simple scientific definition, electricity or an electric charge occurs when electrons jump from one atom to another. An electronic charge is a property of subatomic particles that acts with electromagnetic force. A charge may be transferr... [Read More]
How Generators Work
An electrical generator is a device that converts mechanical energy to electrical energy. The source of mechanical energy may be a steam engine, a water turbine, an internal combustion engine, a wind turbine, or compressed air. The generator works by moving electric current which is already present in the wire. There are two main parts of a generator: mechanical and electrical. The mechanical part... [Read More]
Electrical Setups in Europe and North America
If you have to blame anyone for the confusion generated by having different voltages around the world, point your fingers toward Thomas Edison and Nicola Tesla. But that is water under the bridge now. Because of the apparent difference in how electrical systems are set up in Europe and North America, it is wise to take note of these dissimilarities when traveling. Most of the world, Europe include... [Read More]
What is Voltage?
Voltage is basically the difference of electrical potential between two points of an electronic circuit. Measured in volts, it is the potential energy of electric current. One way when voltage is used is to specify the voltage of a point in a circuit. This is the voltage difference, the reference point being referred to as the ground.The more common instance where voltage is used is to determine t... [Read More]
How Hybrid Cars Work
With air pollution becoming a serious issue today, more and more people are clamoring for an alternative for current vehicles that run on cleaner energy sources. The use of traditional fuels such as gasoline and diesel has amounted to an increase in air pollution worldwide with serious effects to health as well as the environment. One of the best ways seen to be able to bring down air pollution, a... [Read More]
