Chemistry by Nature

Nature is a great chemist. It synthesizes millions of compounds every moment ranging from simple molecules like methane to very complex molecules like carbohydrates, cellulose and proteins. Most of these compounds are synthesized by plants. From the plants they are passed on to animals because the animals cannot synthesize their food by themselves. But there are many chemical reactions occurring inside the cells like breaking down the complex molecules and unlocking the energy which is stored in them. Where does all the energy locked inside the different molecules come from? Most of it is derived from the Sun light. In… Read More »Chemistry by Nature

Brain uses Backup Libraries

In computer programming, there is a kind of programming called modular programming. In this technique, a giant program is broken up into independent smaller units. Each unit in itself a complete program to achieve a sub goal. These units are called “Modules”. All these modules are archived in the libraries like math and header libraries in C++. These modules can be used in any other program where they can accomplish the same task. These modules are very handy and only additional programming lines are added to expand their capabilities. For example, suppose you want to write a program to draw… Read More »Brain uses Backup Libraries

Entropy: A negative form of Information?

Entropy is the measure of degree of randomness in a system. More the randomness more is the system stable. Any reaction which results in the creation of more number of particles or when matter in the solid state goes to liquid state and from liquid state to gaseous state results in increase of entropy. Entropy is related to the heat energy which is the form of energy all other energies when used tend to change into. Heat causes the increase in the randomness of the motion of the particles in the matter. The entropy thus is connected with chaos. It… Read More »Entropy: A negative form of Information?

Cool and Fragrant Shade of Unknown Tree

Heat is building up rapidly and temperature is shooting up. Many trees like Amaltas, Gulmohur and cannonball are bearing beautiful flowers which seem to challenge the Sun‘s assault on the mother earth. Earth is parching up. The delicate flowers of spring season have begun to wither. Soon the grasses will be gone. The hills have become devoid of greenery. Every tree, plant and animal shall be looking up hands raised towards heavens. In the morning, during walks, body begins to perspire profusely and within minutes you feel exhausted.The runnels of perspiration run though the back. The body desires for cool… Read More »Cool and Fragrant Shade of Unknown Tree
