Hawking says a theory is nothing more than a model, which correctly explains a big number of observations. If you come up with the theory that your software startup needs 1,000 clients to thrive and start turning a profit, you almost instantly accept it as true, which leads to lots of disappointment, should you fail in spite of reaching that goal. Nowadays, since we’re grown up, we don’t see theories as what they are any more: educated guesses. For example as a toddler you might have had the theory that a glass will easily survive its fall from the kitchen tableĪ theory, which you probably quickly went on to disprove, much to the frustration of your Mum and Dad. We constantly come up with theories, and then test them. Hawking trained as a theoretical physicist, collaborated with Roger Penrose on gravitational singularity theorems and worked on black hole radiation.If you want to save this summary for later, download the free PDF and read it whenever you want.ĭownload PDF Lesson 1: Theories can never be fully proven.Īs children we’re all scientists.
This first export edition would have been sent to Hawking by his publisher as his personal file copy and remained at his specially designed home at Wordsworth Grove until his death. Hawking’s Brief History was one of the most unexpected bestsellers in publishing history and made a successful physicist into a global celebrity. The same title but in audio book form is also included (with the same blue-rimmed bookplate) – both housed in a custom-made slipcase.
With the posthumous deep blue-rimmed bookplate to the verso of the cover that reads: ‘From the home of Stephen W Hawking (1942-2018) Wordsworth Grove, Cambridge November 2020 G.
Small loss to the corner of the front cover. Small octavo bound in blue photographic card wraps, very little rubbing to extremities.
The author’s copy of the first Bantam Export Edition of 1989, removed from Stephen Hawking’s home in Cambridge after his death.
