Catalysis, the annual fest of the chemistry department Tatva, Hindu College, was held on 5thand 6th March’13. The theme for this year was Environmental Chemistry. The 2-day event started with the inauguration and release of the department magazine, Substance. There was a talk by Dr. Alok Mukherji, Scientific Secretary, Centre of Global Change. The lecture left the audience spellbound. Both the days were filled with various events like poster presentation, fun with lab, general quiz, paper Mache, Antakshari, debate, ad mad, chemical tambola, Pictionary, bring your own waste and treasure hunt. The participation was mostly from the department itself but there were participants, as well as winners, from Physics and Sociology as well. The fest was a huge success, enjoyed by all present.   Surbhi grover ([email protected])]]>
