The world-changing doctoral thesis was signed by Hawking. His doctors gave him just two years to live, and the devastating news led him to lose hope and quit his studies. However there is a very grave difficulty associated with a static model such as Einstein's... "We are now so humble that we would not claim to occupy any special position..."
The motorized chair, used by Hawking after he was paralyzed with motor neuron disease, raised 296,750 pounds in a Christie's online auction.
The proceeds will be donated to two charities - the Foundation of Stephen Hawking and the Association for the fight against motor neuron disease (Motor Neurone Disease Association). Hawking's items all combined sold for about $1,306,275 at the auction.
Some of his belongings including essays, medals, awards and a copy of his book a "Brief History of Time" signed with a thumbprint were sold online on Thursday alongside letters and manuscripts belonging to Isaac Newton, Charles Darwin and Albert Einstein.
Auction items belonging to Hawking also included a copy of his book A Brief History of Time signed with his thumbprint that sold for 68,750 pounds ($89,751), his Alpha Industries bomber jacket that sold for 40,000 pounds ($52,219), and a collection of medals and awards that sold for 296,750 pounds ($387,402). A motorised wheelchair that belonged to the physicist, who died in March and which was expected to fetch £15,000, went for nearly £300,000.
