[Homework]20120326 阿尔伯特·爱因斯坦 Einstein—6
HW
But Einstein wants to understand the real world, and a real world doesn't work that way.
Einstein realized that this theory failed for accelerations. But in our universe everything accelerates. At a bumpy road, jet airplanes, on a subway car...Every thing is accelerating. So it was a defect in special relativity.
On Einstein's imaginary jouney, if a speed varies at all, his theory, his notion of how objects behave in time and space falls apart.
His scientific xxxxxxxxxxxxx applied to all cases.
Einstein knows that for his theory to work, it has to cover everything in the universe and that includes the pervasive and invisible force that holds everything together.
Gravity. Gravity is everywhere. Gravity holds us to the floor. Gravity holds the sun together, the solar system together. Where was gravity in special relativity?
Einstein wants to expand his special theory of relativity into a general theory of relativity. A theory that would explain not just time but also gravity. he realizes he will be fighting more than two centuries of scientific thought, and his hero Sir Issac Newton.
It's 1907 and the twentyeight year old Albert Einstein is still at the patent office bureaucrat.
It has been two years since he publised his special theory of relativity, and the ambitious Einstein decides to advance even more radical interapretation of the universe on general theory of relativity. Doing this would require him to take on his scientific hero Sir Issac Newton.
In Einstein's time, Issas Newton was god.
Newton was the founder of modern science. This is the actual first edition of Newton's Principia Mathematica of 1687.
This priceless artifact is the very very famous book which became the foundation of universal physics for centuries until Einstein upsets the apple caught.
It has been almost 250 years since the apple fell from the legendary tree on Issac Newton's estate, giving Newton the inspration to formulate his law of gravity.
Newton said that for object falls it is because of a mysterious force called gravity, pulling...
