Use of science concepts in daily lives



What is Science?

''Science is a systematic and logical study towards how the universe works. Science is a dynamic subject. Science can also be defined as the systematic study of the nature and behavior of the material and physical universe, based on observation, experiment, and measurement, and the formulation of laws to describe these facts in general terms.''

''Science is one of the greatest blessings to the mankind. It has played a major role in improving the quality of living of the man. Science is omnipresent and omnipotent in every walk of our life. In every inch of our body, science is the protagonist.''

There are different types of science:

1. Physical Science: Physics, Chemistry, Astronomy and Earth science are branches of physical sciences.

2. Life Science: Biology and Social sciences are branches of life sciences.

3. Applied Science: Engineering and Health care are branches of applied sciences.

Science is involved in cooking, eating, breathing, driving, playing, etc. The fabric we wear, the brush and paste we use, the shampoo, the talcum powder, the oil we apply, everything is the consequence of advancement of science. Life is unimaginable without all this, as it has become a necessity.

Basic science concepts behind few daily applications of science

Cooking: Heat energy is transformed to the cooking vessel in the form of radiation, conduction and convection. After the heat energy is passed the various ingredients like, salt, sugar or any edible material starts breaking bonds and forms new bonds which gives us delicious food. Therefore, physics as well as chemistry is involved. In order to prepare the perfect delicacy, the perfect proportions of the ingredients are very important. Hence math's plays a major role too.

The food which we consume, when entering into our body, undergoes many chemical reactions which is the reason for our energy. The chemically reacted food interacts with various cells present in our body and these cells transfer the proteins, carbohydrates and fats present in the food to our body through various mechanisms. Biology as well as chemistry is involved in this process.

Vehicles: The fuel in the vehicles are burnt in order for the vehicle to get energy. The concept involved in the burning of the fuel is combustion. The conversion of heat energy into electrical energy and mechanical energy takes place. Hence chemistry and physics are involved.

Household appliances:

Mixer / Juicer: It converts the electrical energy into mechanical energy. It uses the principle of centrifugal force.

Refrigerator: Electrical energy is converted to heat energy where cooling takes place.

Air Conditioner: It keeps us cool in summers. Uses electrical energy.
