A murit Stephen Hawking, fizician englez, teoretician al originii universului și unul dintre cei mai mari cosmologi contemporani, profesor la catedra de Matematică la Universitatea Cambridge, deținută cândva de Isaac Newton.
Principalele domenii de cercetare sunt cosmologia teoretică, relativitatea generală și mecanica cuantică. În anii 1965-1970 Hawking elaborează un model matematic asupra originii și evoluției universului în expansiune, din momentul „marii explozii” inițiale („The Big Bang”) și întreprinde studii asupra relației dintre găurile negre din univers și termodinamică. Stephen Hawking avea 76 de ani.
BBC World News: Stephen Hawking dies aged 76
Stephen Hawking has died at the age of 76, his family has said.
The British physicist was known for his work with black holes and relativity, and wrote several popular science books including A Brief History of Time.
„We are deeply saddened that our beloved father passed away today,” a family statement said.
At the age of 22 Stephen Hawking was given only a few years to live after being diagnosed with a rare form of motor neurone disease.
The illness left him wheelchair-bound and largely unable to speak except through a voice synthesiser.
His family said that he died peacefully in his home near Cambridge University, where he did much of his ground-breaking work on black holes.
In the statement his children, Lucy, Robert and Tim said: „He was a great scientist and an extraordinary man whose work and legacy will live on for many years.”
