Now a days lots of result is done in the field of energy science. Energy science may include biodiesel, solar energy and other many energy resources. I have compiled the list of best or top 20 journals of energy science. If you are researcher in this field you can search these journals and try to contribute their articles for the same. The ranking is done on the basis of impact factor of journals. Continue reading “Best journals of Energy of 2011”
Cosmology is a science related with the space. It can be divided into two parts. one is the physical cosmology and other is the modern cosmology. Physical cosmology deals with the origin, evolution and future of the universe. There are various cosmological events which can affect the earth. The events like speed bump, black hole, asteroids ( a large one) and supernova can affect the life on earth.
Supernova is a stellar explosion, can result in a burst of explosion and can outshine the entire galaxy. During a small interval supernova supernova is expected to radiate a large amount of energy which is equal to energy radiated by the sun in his whole life.
Literally black hole means where gravity prevents anything to escape even the light. It is called black because it reflects nothing.
This cosmological events can definitely affect the earth. If you know more events, then please share with us.

We all know about nucleus in an atom and there are particles neutrons and protons in the nucleus. These particles are binded together by strong nuclear forces. At the end of this article, you will be able to understand the following concepts: Continue reading “Nuclear force properties”
There is a law in physics commonly known as inverse square law. As the name suggests, in this law some quantity is inversely related to another quantity. Let us discuss in detail. Continue reading “What is Inverse square law”
Gravitational force is the weakest force in nature. There are many properties of gravitational force, but first of all let us discuss about the various fundamental forces present in nature. There are mainly four types of forces exist in nature:
1. Gravitational force
2. Weak nuclear force
3. Electromagnetic force
4. Strong nuclear force.
Today I will discuss about the gravitational force
We all know that earth and other planets revolve around the sun but why? We are attracted towards the earth due to gravity of earth or in simple words force of attraction of earth. Basically gravitational force is the force between any two objects. The objects can be microscopic or macroscopic. Continue reading “Gravitational force and its properties”
You must have heard the terms dispersion and spectrum. For example, in easy words the RAINBOW pattern is called spectrum and this happens due to dispersion. Let us discuss these two in detail: Continue reading “Dispersion and Spectrum”
Do you know that metals we used in daily life like aluminium, copper etc. are extracted? There are different steps involved in extraction of metals. Let us discuss them one by one:
1. Crushing and Grinding
First of all, ores are crushed into a fine powder in big jaw crushers and ball mills. This method is called pulverization. Continue reading “Steps involved in Extraction of metals”
