The author of this site is me -- Kaustubhan Srivathsan. I am a Mechanical Engineer (NIT Surathkal, India), MBA from the prestigious IIM Calcutta, and have more than 30 years of practical experience in industry (mainly automotive industry). In my career, I have been Vice-President of Engineering /Chief Technology Officer at various companies such as top car manufacturer , and a global Engines company . I decided to do this site out of passion and sheer interest to help students to get through physics as easily as possible, saving a lot of time, energy and efforts. I believe that a student who understands physics concepts well has a strong chance to become a great and practical engineer or scientist in future. Aditya Kaustubhan , B.E. in Computer Engineering , has contributed to the idea of this site, and more specifically the valuable inputs of what a young generation would like to see. This has led to improvements which have gone to make physicsmodels popular among a variety of readers. Aditya is an active proponant of providing free access to education for students the world over.
