The human body has more than 600 muscles. They do everything from pumping blood throughout the body to helping us lift something heavy. Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle.

All hot bodies emit heat by the process of radiation. Radiation of heat does not require a medium. Sunlight comes to the earth because of radiation as there is no medium present between the atmosphere of the earth and the sun.
One can feel the heat of bonfire by standing around it. We get warmth from the room heater because of radiation.

The story portrays a lively depiction of Franz. He loved to spend his day out of doors rather in the classroom because the brightness of the sunshine, the chirping of the birds and the liveliness of the nature fascinated him. He was not much in interested in studies. However, he got saddened when he came to know of the order from Berlin that French would no more be taught in school. Suddenly, he realised what he was going to lose. To lose one's language is nothing less than losing oneself. He knew he had not yet learnt even the participles clearly. His power of self analysis led him to conclude that the lessons of French were never difficult. It was he who never paid attention. Now, when he understood the language, the authorities restrained this learning. He got disturbed to see the exploitation of one human race by another. This made him ask "Will they make them sing in German, even the pigeons?”. Franz turns out to be a character that grows mature in the course of the story. From a negligent school boy he finally becomes a self analysing citizen.

क्युबा एक तटीय क्षेत्र है जो अमेरिका के पास है। वहां पर सोवियत संघ का शासन था। सोवियत संघ के नेता निकिता ख्रुश्चेव थे। जिन्हें डर था कि अमेरिका कही क्युबा पर अपना अधिकार न जमा ले इसलिए सोवियत संघ ने अपने हथियार वगेरा क्युबा में तैनात कर दिए । इसकी खबर अमेरिका को कुछ दिन बाद लगी तब अमेरिका ने अपने जंगी बेड़े आगे किये। इस स्थिति में कभी भी युद्ध ठन सकता था पर दोनों तरफ से समझदारी दिखाई गयी और युद्ध नही हुआ । दोनों तरफ से हथियार लगाने को ही क्युबा मिसाइल संकट कहा जाता है। यह 1962 में हुआ था।
