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

By any means tenable or Untenable

Thermodynamics is the most important branch of the science dealing with the energy, work and conversions of one form of energy into other forms. It cuts across many branches of the courses like physics, chemistry and engineering. All the students in these streams have to come face to face with this subject. Its laws have become so perfect that they can be bound into mathematical equations. First law of thermodynamics is concerning the conservation of energy.¬† Suppose there are two systems which are having energies A & B. If they are connected, then the energy of the resultant system shall… Read More »By any means tenable or Untenable

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?

What Color are the Atoms?

Atoms are the smallest units of matter which are independent and have a definite address. Atoms of different elements are different in many aspects but size and atomic weight are the main attributes. I think there is no such thing as color of things. Color exists only when there is light.When the darkness falls, the color of things begins to dissolve and black color takes over everything. Black color thus obliterate all the differences due to colors. May be this is the reason why in Hindu mythology many Gods are dark complexioned. Take for example Rama, Krishna and Draupadi, all… Read More »What Color are the Atoms?

What is inside an atom?

Atoms are thought to be the smallest entities that take part in the chemical reactions. They join with each other in different ratios to form the molecules which then combine to form macromolecules. The molecules can exchange atoms with other atoms or molecules to give rise to different molecules. Atoms are not the fundamental particles of the matter. Even an atom contains protons and neutrons confined in a very small space called nucleus in the core of the atom and electrons occupy the rest of the space. Electrons are negatively charged particles and counterbalance the positive charges on the protons… Read More »What is inside an atom?
