Today, in the morning when I was teaching my sister about numbers, viz. rational numbers and irrational numbers, this one was created. My sister, Kavita Tiwari, is in Vth grade and mainly study Math ,Science and Social Science. On last wednesday we visited a Circus show. We all liked that very much. And she became a fan of a girl acrobat. She always says that female acrobats are far better than male acrobats in circus-shows having rope-walk show. Male acrobats look like they are about to fall, but female ones are frank in this work. When I discussed with her about some constants like etc., she asked me to stop for a while, and started making this cartoon. Her thoughts were mingled with math. I was surprized by the meaning this cartoon had. I really liked her stuff, and thought to post it on the web.
