1) The ratio of Laplace transform of output to Laplace transform of input assuming all initial conditions to be zero.

2) The transfer function of a system is the Laplace transform of its impulse response under assumption of zero initial conditions.

3) Replacing ‘s’ variable with linear operation D = d/dt in transfer function of a system, the differential equation of the system can be obtained.

4) The transfer function of a system does not depend on the inputs to the system.

5) The system poles and zeros can be determined from its transfer function.

Climate change has reduced human security and threatened human well being. An ignored reality

of human progress is that human security largely depends upon environmental security. But on the

contrary, human progress seems contradictory to environment security. To keep up both at the

required level is a challenge to be addressed by one and all. One of the ways to curb the climate

change may be suitable scientific innovations, while the other may be the Gandhian perspective on

small scale progress with focus on sustainability.
