Dr. S. Palaniammal’s is a specialized textbook for engineering students, particularly those in Electronics and Communication (ECE), Computer Science, and Information Technology.
One chapter, on martingales, felt like a secret. The property that future expectation equals the present pulled him up on nights when hope felt precarious. It whispered that, under the right balance, randomness could be fair. He began to apply the idea beyond walks with random steps — to friendships, to trust, to bets on himself. He learned to avoid gambles that promised quick wins and to place steady, reasonable stakes on things that matured over time. One chapter, on martingales, felt like a secret
“A random process is a collection of time functions (or waveforms) associated with the outcomes of a random experiment. Each outcome yields one waveform; the entire ensemble forms the random process.” He began to apply the idea beyond walks
One evening, during a power cut, Ramesh traced a random walk on a candlelit page. He scribbled a thought: what if life were not to be predicted but to be designed — not to avoid chance, but to harness it? He imagined a small class he could teach, where students learned not only formulas but how to live with uncertainty: how to take risks with guardrails, how to measure and accept probabilities without letting them paralyze. and standard distributions (Binomial

The book includes a vast number of illustrative examples with step-by-step solutions, helping students grasp difficult concepts like queuing models and networks.
Basic probability theory, random variables, and standard distributions (Binomial, Poisson, Exponential, etc.).
