Technothlon has been providing students across India a once in a lifetime experience since its inception, and this year was no different. This year, the top 50 teams in both the Juniors and Hauts categories got an incredible opportunity to meet and interact with Prof. Frederick J. Raab, the head of the observatory where Gravitational waves were discovered, and Dr. Amit Sethi, one of IIT Guwahati’s most distinguished Professors. Dr. Amit Sethi’s interactive session on Machine Learning and Cancer Treatment, and Prof. Raab’s interactive session on Gravitational waves inspired the students and gave them an experience they’ll remember for years to come.
