Stephen hawking

Stephen Hawking – life and accomplishments Stephen Hawking was the famous English physicist and cosmologist who rose to huge acclaim after publishing several innovative works on black holes and other cosmological events in the universe. According to the University of Cambridge graduate, black holes emit a kind of radiation which experts now call the Hawking radiation. Born in Oxford, England, Hawking’s development was characterized by an insatiable appetite to completely understand the universe. The extraordinary physicist always maintained that his goal was to find answers to questions about why the universe existed at all, and why it existed in the way it does. In spite of spending more than half of his adult life confined to a wheel chair (since his diagnosis with amyotrophic lateral sclerosis – ALS), Hawking remained determined to push the boundaries of physics and by so doing became one of the most recognizable faces of the 20 th century. World History explores the history and accomplishments of Stephen Hawking, one of the greatest theoretical scientists and cosmologists of the modern era.

Lived 1942 – 2018. Stephen Hawking was a theoretical physicist and cosmologist, widely considered to be one of the greatest scientists of his time. He was the first scientist to devise a cosmology that married the general theory of relativity and quantum mechanics, and he made huge contributions to our understanding of black holes. Hawking wrote a number of popular science books including the bestseller A Brief History of Time. Advertisements Early Life and Education Stephen Hawking was born on January 8, 1942 in Oxford, England, UK. His father was Frank Hawking, an English biologist; his mother was Isobel Walker, a Scottish Philosophy, Politics and Economics graduate; both parents were graduates of the University of Oxford. Stephen had two younger sisters and an adopted brother. Stephen Hawking was an average student at school, deeply interested in science. After winning a scholarship in Natural Sciences at age 17, he graduated at age 20 with a first-class honors degree in Physics from University College, Oxford. Thereafter, Hawking carried out research at Trinity Hall, University of Cambridge, for a PhD in Astronomy and Cosmology. In his early days at Cambridge, at age 21, Hawking was diagnosed with Amyotrophic lateral sclerosis (ALS), a motor neuron disease in which the nerves controlling the muscles become inactive while the sensory nerves function normally. At first his doctors expected him to die within two years. Due to this sustained condition, it took him about 40...

The world lost one of its most brilliant scientific minds Wednesday, when legendary physicist Stephen Hawking Hawking’s cause of death was likely amyotrophic lateral sclerosis, or ALS, a neurodegenerative disease that wears away at nerve and muscle function over time. He was first diagnosed with ALS more than five decades ago, at age 21, and was initially given just a few years to live — making the very nature of his long, illustrious career as much of a scientific marvel as the Here’s what to know about ALS, and what may have allowed Hawking to beat the odds for so long. What is ALS? ALS, also known as Lou Gehrig’s disease, is a progressive neurodegenerative disease that erodes motor neurons — cells in the brain and spinal cord that control muscular function — until it becomes difficult or impossible for a person to walk, talk, speak, swallow and breathe, While there’s no cure for ALS, the condition can be managed with medication, physical therapy, occupational therapy and speech therapy. Some patients also use ventilators to assist with breathing. Who gets ALS? Doctors aren’t totally sure what causes ALS in most cases, though it does appear to have a genetic component in some people, according to the Mayo Clinic. It’s usually diagnosed in people between ages 40 and 60, and men seem to be more likely than women to develop the condition, at least before the age of 65, the Mayo Clinic says. How rare is Hawking’s longevity? Quite rare. Just 5% of ALS patients live longer tha...

Before he passed away in March, theoretical physicist Stephen Hawking had published On Wednesday, the Journal of High Energy Physics Wait, what? If you asked an astrophysicist today to describe what happened after the Big Bang, he would likely start with the concept of “cosmic inflation.” Cosmic inflation argues that right after the Big Bang — we’re talking after a teeny fraction of a second — the universe expanded at breakneck speed like dough in an oven. But this exponential expansion should create, due to quantum mechanics, regions where the universe continues to grow forever and regions where that growth stalls. The result would be a multiverse, a collection of bubblelike pockets, each defined by its own laws of physics.

After the Big Bang and inflation, the expansion of the universe gradually slowed down for the next several billion years, as the matter in the universe pulled on itself via gravity. More recently, the expansion has begun to speed up again as the repulsive effects of dark energy have come to dominate the expansion of the universe. Image and caption by NASA “The local laws of physics and chemistry can differ from one pocket universe to another, which together would form a multiverse,” Hertog said in Along with being difficult to support, the multiverse theory, which was “As a consequence, Einstein’s theory breaks down in eternal inflation,” Hertog said....
