# What can we learn from Ramanujan

**"You are industrious, why do you use a slate when you have to do so many calculations? Why not paper ?** Once Ramanujan's friend asked .

Ramanujan's sombre reply was, **"When food itself is a problem, how can I find money for paper?" "I may require four reams of paper every month."** Mystification induces awe, but the narrative's determination inspires. He did not give up, though he failed many times. For a generation yearning for independence and progress, Ramanujan was an inspiration.

Ramanujan's note book, which contained a unique family of identities that Srinivasa Ramanujan called "mock theta" functions, was written in 1920. Mathematicians use bizarre mock theta functions to explore how to make the internet more secure, 🔐 physicists use them to comprehend incomprehensible black holes and understand how fundamental particles interact with each other. Even after 100 years, *Srinivasa Ramanujan keeps us motivated not only as a mathematical genius but also as a person who followed his passion even amidst adversities.*
