A) He wanted to challenge Newtonian physics.
B) He wanted to create a theory that would explain gravity in a new way.
C) He had an ambition to become world-famous.
15) What is TRUE about Albert Einstein’s early career in science?
A) The publication of the Special Theory of Relativity didn’t bring him immediate recognition in the scientific community.
B) His work at the patent office inspired Einstein to start doing research.
C) From the very beginning his ambition was to do something revolutionary in science.
16) What is NOT TRUE about Isaac Newton’s scientific masterpiece “Principia Mathematica”?
A) The laws formulated in this book dominated physics for nearly two hundred years
B) The Law of Gravity formulated in this book was not quite accepted by Albert Einstein.
C) In this book Isaac Newton coined the term ‘gravitational pull’ for the mysterious force which makes objects fall.
17) Why wasn’t Max Plank very enthusiastic about Einstein’s decision to work on gravity?
A) Because he didn’t believe in Einstein’s success in this field.
B) Because he completely supported Newton’s ideas of gravity.
C) Because it was an extremely complicated problem.
