The Earth have one natural satellite; the Moon. The moon is the closest natural celestial body seen to the naked eye from Earth. Scientists believe it has helped shaped life and climate of the planet over the eons. But is there really any use of it? If so, how can we make use of it? Let's look into some possibilities..

The Sun produces massive amounts of energy by a process called nuclear fusion where Hydrogen atoms are combined to form Helium atoms. This energy is emitted to space in the form of electromagnetic radiation. After 8 minutes of journey, a portion of it arrives on Earth with an estimated energy density over a 1000 Watts per square meter. About 30% of this energy is reflected back to space. The rest of it powers up the planet as we know it. On Earth, energy arrives in the form of electromagnetic waves including Infra-red (IR), visible light and Ultraviolet (UV). We refer to it as “ sunlight ”. The following list is a composition of the main forms of energies produced from solar energy and stored on Earth.

Our eyes perceive light. Our brains interpret it into shapes and forms that we are familiar with. What we see is lighter or darker depending on how much of light enters the eye (that is; intensity) and is applied with "colors" based on the flavors of light we receive. As vivid as they may be, these so called flavors of light are physically non-existent in nature. They are solely an interpretation that exists only within our perception.

There are 3 distinct states of matter: solid, liquid and gas. The molecular differences between these states are determined by the ability of their kinetic energies to overcome the forces of attraction among the molecules. Out of them, Gaseous state of matter exhibits the highest degree of freedom for movement in 3 dimensional space. This allows gases not only to acquire the shape of the container but also to adapt its volume to occupy the container as well. Interestingly, these moving gas molecules are responsible for three major phenomena distinct from each other.

Have you ever wondered why plants and trees growing at the margins of pools and lakes of water look magically beautiful? They grow branches and leaves towards the water. They grow along and across the water surface but never touch it. How is that even possible? Let's look at the processes involved in plants to produce this eye-catching scenery.

In our childhood, we are taught of counting with fingers. Regardless of the age, people continue to use these techniques to ease up calculations that come across in day to day living. While your fingers allow you to count and represent up to 10, did you know that there is an insane potential capacity of number representation by your digits(fingers).

Calculating area of geometry with curved lines is more challenging than shapes with straight lines. The area of a circle is typically calculated πr 2 with Calculus. It's the value we accept and use. But did you know that we can derive the formula A=πr 2  in a more easier way to see why it is the way it is..
