Physics – A Scientific World View
Scientific Method
Einstein’s view of scientific processes
☛ A scientist makes a creative leap based on intuition to explain physical phenomena
☛ A powerful idea/axiom has many consequences
☛ The scientific process begins when the scientist develops consequences based on the idea/axiom
☛ Test these consequences against the real world
