An Education in Science Class 8 English Wind Chimes Solutions Word Meanings Summary

An education in Science Class 8 Wind Chimes: This is an extract from Stephen Hawking’s Black Holes and Baby Universes and Other Essays. Stephen William Hawking (1942-2018) was a renowned scientist and the director of research at the Centre for Theoretical Cosmology at the University of Cambridge. His book A Brief History of Time appeared on the British Sunday Times best-seller list for a record-breaking 237 weeks.


Mr Hawking discusses different perceptions about science and its effects. He says that one cannot stop enquiring minds from thinking about basic science. He wishes that changes in science and technology are in the right direction. It is very important for the people to have a basic understanding of science, so that they can make informed decisions and not leave everything in the hands of experts. The public has ambivalent attitude towards science. The public distrusts science because they don’t understand it. We get to see this in the cartoon character of a mad scientist, working in his laboratory to produce a Frankenstein. Somehow, the public also has great interest in science, particularly astronomy. He emphasises that despite all this the public needs to make informed decisions on subjects like acid rain, the greenhouse effect, nuclear weapons and generic engineering. For this he goes back to the school and relates it to the way science is taught in the schools. It is presented in a very dry and uninteresting manner. Most of the children learn it by the rote methods to pass examinations. They hardly see its relevance in the world around them.

It is also because science is usually taught in terms of equations. Though equations are a concise and accurate way, they often frighten people. He himself wrote a popular book, for which he was advised not to include equations because that would reduce the sales. These equations serve good only to the scientists and engineers, but for the rest of the people a qualitative grasp of scientific concepts is sufficient, which could be conveyed by diagrams, without the use of equations. He gives some tips to improve the scientific temperament in people. And here he talks about the role of television that can reach a truly mass audience. Television does have some good programmes. He believes that producers of television science programmes should realise that they have responsibility to educate the public and not just entertain them. He goes further, talking about the East-West tensions and the horrors of nuclear war. Nuclear weapons are still poised to strike all the major cities in the Northern Hemisphere.

He shows his worry that even smaller powers are acquiring nuclear capabilities. Even a small glitch or error or mutiny can jeopardise the world and the people.
