Nobel prize winner Albert Einstein is one of the greatest scientists who ever lived. By power of thought alone, he gave us a fresh conception of the universe. He showed us that space and time are elastic - shrinking or expanding, speeding up or slowing down, depending on your movement. Join him for a coffee and he'll tell you all about his revolutionary work on relativity, his quest for a grand unifying theory of the cosmos, and personal matters too - from the pleasures of sailing and music to his anxieties about the nuclear bomb he had helped to unleash. His patient, down-to-earth answers to all questions will make everything amazingly clear.
