Stephen Hawking was born on 8 January 1942 to Dr. Frank Hawking‚ a research biologist‚ and Isobel Hawking. He had two younger sisters‚ Philippa and Mary‚ and an adopted brother‚ Edward.[11] Though Hawking’s parents were living in North London‚ they moved to Oxford while his mother was pregnant with Stephen‚ desiring a safer location for the birth of their first child. (London was under attack at the time by the Luftwaffe.)[12] According to Hawking‚ a German V-2 missile struck only a few streets away

Today I will introduce a famous and outstanding scientist to you. A brief history of Stephen Hawking. The main contents include four aspects Stephen William Hawking is an English theoretical physicist and cosmologist‚ whose scientific books and public appearances have made him an academic celebrity. Stephen William Hawking was born on 8 January 1942 (300 years after the death of Galileo) in Oxford‚ England. His parents’ house was in north London‚ but during the Second World War Oxford was considered

radiation We can classify radiation into ionizing and non-ionizing radiation‚ according to the effects it produces on matter. Ionizing radiation includes cosmic rays‚ X rays and the radiation from radioactive materials. Non-ionizing radiation includes ultraviolet light‚ radiant heat‚ radio waves and microwaves.In medical practice ultrasound and magnetic resonance imaging (MRI) involve non-ionizing radiation. +light n heat radiation produced by the sun *ionizing radiation is produced by some

I chose Stephen Hawking to write about for my case study because I have always found him extremely interesting. As a fellow atheist he has come pretty outstanding scientific theories on how our universe came about‚ none of which are attributed to some fictitious being. I am also inspired with the amount that Hawking has done so far in his lifetime. All this has been done in spite of‚ or because of‚ having ALS. As a medical professional I am in awe of the things that he has accomplished. Stephen

OF STEPHEN HAWKING AND HISTORY OF TIME It is the ultimate irony that the “finest mind alive” today is a mind held captive in a speechless‚ dying and withering body! It is the mind of Stephen Hawking – world’s leading Cosmologist and most brilliant and original theoretical physicist. Presently the Lucasian professor of mathematics at Cambridge‚ he has been proclaimed as the greatest genius of the late 20th century. Yet‚ as he lies limp in his wheel-chair‚ weighing only 38 kilos and not even

Answer: Radiation has a profound effect on matter. Particularly in forms where it has high energy. There are basically two kinds of radiation‚ and they are electromagnetic energy and particulate radiation. Low energy electromagnetic radiation isn’t generally hazardous‚ as long as the field strengths are low. You wouldn’t want to stand in front of a radar antenna when it’s radiating‚ but we are swept by low power electromagnet energy all the time. Those so-called radio waves are everywhere. Light

Concepts of Radiation Radiation * Emission of energy from an atom and the transmission of this energy through space. * Energy propagated in a material medium or space. * Energy in transit. What are the types of radiation? * Radiation is of two general types in our environment. * They are called non-ionizing and ionizing. Ionization * the energy transferred to the electrons causes them to be pulled away or removed from an atom entirely. * The result is the
