SENSORS IN MOBILES

As I hear the word sensors, first thing that strikes my mind is our sense organs. Sense organs are the vital part of our body which are responsible for “response to stimulus” action. When there is any external stimuli to our body, there will always be a reaction to that action. Brain the superior power which takes the decision accordingly. Sensors of the electronic world behaves exactly like the sense organs of our body. What are sensors used in electronic world? Sensors are sophisticated device which senses, detects and responds accordingly. It’s a type of transducer, which has electrical signals

WHY DO CHAMELEONS CHANGE THEIR COLOUR?

Every day we are surrounded by the beauty of colours in nature. Nature is indeed a bag full of surprises as it never fails to capture my attention. Every life that exists on Earth has been designed intricately and ingeniously. All creatures have different structures, adaptabilities, colours etc. Chameleons are one such unique creature that exists in nature.

Though this technique helps in the improved production there is always a risk factor involved. Some

Nuclear fusion in the Sun

Sun is well known for its extreme hotness. Nuclear fusion reaction is responsible for it. Even before we know how nuclear fusion happens in sun. Let us just understand what nuclear fusion reaction is? Nuclear fusion Nuclear fusion is nuclear reaction in which two or more nuclei combine to form a massive structure. It is an exothermic reaction. So when the collision of nuclei is happening there will be lot of reactional outcomes. Heat, light etc. are results of exothermic reactions. Generally the fusing nuclei have lower masses. So the energy released during this reaction is due to interaction between

Do You Know Which Is The Most Abundant Element In The Earth’s Atmosphere?

When asked people about the most abundantly available element in earth’s atmosphere, they tend to say it is either oxygen or carbon dioxide.
