 The 43-Second Descent- Why the History of Hiroshima is Darker Than Your Textbooks Claim 1. The Day the Sun Descended: A Monday Morning Like Any Other A deceptive peace hung over Hiroshima on the morning of Monday, August 6, 1945. Summer was in full force, the sky was a clear, pleasant blue, and the sun was shining with a warmth that betrayed nothing of the impending furnace. At 8:00 AM, the city hummed with the mundane rhythms of a society at war but still functional: adults were filing into their offices, and children had just settled into their classrooms for the first period of the school day. The tranquility was briefly punctuated by the sighting of an American Boeing B-29 aircraft high in the sky. To the residents below, it was a distant speck; at 8:15 AM, when an object was released from the plane, people watched with a curious, oblivious detachment.

Electrostatics- Electric Charges and Fields

Image
  Chapter 1: Electric Charges and Fields 1.1 INTRODUCTION (Electrostatics) Meaning of Electrostatics Electrostatics is the branch of physics that deals with the study of electric charges at rest and the forces, fields, and potentials associated with them. The word static means unchanging with time. Hence, electrostatics concerns itself with situations where charges are not in continuous motion, unlike current electricity. Everyday Experiences of Electrostatics Electrostatic effects are commonly observed in daily life, such as: crackling sound while removing synthetic or woollen clothes Attraction of small paper bits by a rubbed comb Electric shock while touching a metal door after walking on carpet Lightning during thunderstorms These phenomena occur due to accumulation and sudden discharge of electric charges . Cause of Electrostatic Phenomena Electrostatic effects arise mainly due to a. Rubbing of insulating surfaces b. Transfer of electrons c. Imbalance of electric charges No n...
