"Passion is the genesis of genius" - Galileo Galilei Hi! I'm Jainam Khara , popularly known as PNJ Sir — a Physics teacher by profession, but a student of curiosity for life. The name PNJ (P for Physics, J for Jainam) was given to me during my time at Lakshya, and it’s grown into a brand — from this blog, to my Instagram page, to every classroom I step into. I hold a Master's in Physics from IIT Bombay and have been teaching for over 15 years , ever since I first picked up the chalk at the age of 15. My mission has always been to make students fall in love with Physics — not fear it. Because when passion for a subject is ignited, it creates purpose , and purpose pushes you toward your best self . Currently, I’m teaching at the Vedantu Learning Center at PCMC Pune , which became India’s Best Vedantu Offline Center in just 4 months. I’ve mentored thousands of students for IIT JEE , NEET , and IIT JAM , and many of them are now at IITs, IISERs, and other top insti...
Who is Sharad Kaandi? Sharad Kaandi is my clickbait - a quirky, curious, and somewhat clueless character I created (way back in 2014) to make physics problem-solving more relatable, fun, and engaging. He’s the kind of guy who’s always surrounded by physics but can never quite figure things out without help—making him the perfect guide for students who sometimes feel the same way! Why did I create Sharad Kaandi? The idea behind Sharad Kaandi was to break the monotony of typical physics problems. By introducing humor and storytelling, I want to show that physics isn't just a set of abstract concepts—it’s part of our everyday world, full of surprises and fun. Sharad's adventures are filled with odd scenarios where physics is the key to solving all kinds of problems, often with a twist of humor and creativity. What will you find here? On this page, you'll find PDFs of physics numericals involving Sharad’s adventures. These problems cover various topics, from Classical Mechani...
