All of us in our every day lives heard and see Telescope. How all these telescopes work ?
Telescope works on two basic principles of Optics (optics is the branch of physics which deals with the study of light and its interation with matter)
The two basic principles are Reflection and Refraction.
Reflection means redirection of light to another direction when it encounters two different media.

Refraction is bending of light rays when it passes from one media to another media.

We will discuss in detail regarding telescopes in next discussion

Do you know how your spray bottle works ?
Have you ever thought how my spray bottle working ?
It works based on " Bernoulli principle" . Which states that as velocity increases pressure decreases.
just observe the above image . As you force air through nozzle , the upper portion of paint bottle becomes low pressured region when compared with pressure in bottle. So in order to compensate this inbalance this is replaced by fluid in paint bottle as shown in figure.
This events are observed in our day to day lives. See how science as a language describe this simple events.

Save Earth
We have only one Earth to live in. We are using natural resources with out control. Even we are using our feature generation resources.
Think on it we are destroying the future of our children.
