#Things to consider
- The universe is a large space where bodies attract one another by means of forces; and there is a universal force, gravity: every body attracts every other body.
- Space is not a dull, fixed container but possesses its own dynamic, its own “physics,” just like the matter and the other fields it contains.
- The entire technology of the nineteenth century and of our own modern world rests largely upon Newton’s formulas.
- Einstein wrote three major articles at the age of twenty-five.
- It is easy to understand things once someone has thought them through. The difficulty lies in thinking them through in the first place.
