Stephen Hawking Notes, Summary, Questions | Class 10 SSC

This chapter is an informative biographical sketch about Stephen Hawking, a renowned British scientist, professor, and author. It highlights his immense contributions to cosmology and physics despite suffering from a severe motor neuron disease.

About the author

The chapter is an inspirational account detailing the life, academic journey, literary works, and physical challenges of the brilliant theoretical physicist Stephen Hawking.

Summary

Stephen Hawking was born on January 8, 1942, and studied cosmology at the University of Cambridge. At the age of 21, he was diagnosed with amyotrophic lateral sclerosis (ALS), a disease that progressively shut down the nerves controlling his muscles. Doctors initially gave him only two and a half years to live. However, seeing a roommate with leukemia in the hospital and having a dream about execution made him realize he still had things to do, pushing him to pour himself into his research.

Before his diagnosis, Hawking had been bored with life, but the fear of not living long enough to earn his Ph.D. completely changed his focus. As his physical condition worsened—requiring a wheelchair by 1969 and a tracheotomy in 1985 that made him lose his natural voice—his career continued to soar. He became world-famous after publishing 'A Brief History of Time' in 1988, which became an instant bestseller and brought complex concepts of space and time to the general masses.

Due to losing his voice and muscle control, a computer programmer in California helped him by providing a speaking program operated through a sensor on his cheek muscle. Despite constant health concerns and severe physical limitations, Hawking continued writing at a prolific rate until his passing on March 14, 2018, leaving behind an inspiring legacy of resilience and brilliant scientific inquiry.

Word meanings

Important questions and answers

Q1. What medical condition was Stephen Hawking diagnosed with at age 21?

At the age of 21, Stephen Hawking was diagnosed with amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), where the nerves controlling his muscles were shutting down.

Q2. Which book brought Stephen Hawking international prominence in 1988?

The publication of 'A Brief History of Time' in 1988 catapulted Hawking to international prominence, becoming an account of cosmology for the masses.

Q3. How did Stephen Hawking communicate after losing his voice in 1985?

After losing his voice following a tracheotomy in 1985, he communicated using a computer speaking program and speech synthesizer directed by a sensor attached to his cheek muscle.

Q4. What were the two key events that prevented Hawking from becoming completely despondent after his diagnosis?

The first event was sharing a hospital room with a boy suffering from leukemia, which made his own situation seem more tolerable. The second event was a dream he had about being executed, which made him realize he still had things to do with his life.

Q5. What was Hawking's ultimate scientific search known as 'science's Holy Grail'?

It was his search for a single unifying theory that can combine cosmology (the study of the big) with quantum mechanics (the study of the small) to explain how the universe began.

Q6. What did Hawking conclude regarding the creation of the universe in his 2010 book 'The Grand Design'?

He concluded that the Big Bang was the inevitable consequence of the laws of physics and nothing more, stating that the universe can and will create itself from nothing because of a law like gravity.

Q7. State whether the following statement is true or false and justify using a line from the text: 'Stephen Hawking was diagnosed with Alzheimer’s disease.'

The statement is false. Justification from the text: 'At the age of 21, Stephen Hawking was diagnosed with amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease).'

Q8. Explain how Stephen Hawking's life proves the proverb 'Every cloud has a silver lining'.

Before his diagnosis, Hawking was very bored with life and felt nothing was worth doing. However, the shocking news of his fatal illness made him realize he might not live long enough to finish his Ph.D., which drove him to pour himself into his research and eventually become one of the world's greatest theoretical physicists.
