The Three Major Conflicts 1. Conflict between Newton’s law of motion and Maxwell’s law of electromagnetism: • Newton’s laws---run fast enough‚ you can catch up a beam of light. • Maxwell’s electromagnetism---no matter how hard you chase after a light beam‚ it still retreats from you at light speed. • This conflict gave birth to special theory of relativity • According to special relativity‚ space and time depend on one’s state of motion. 1 2. Conflict between Einstein’s

its small gravity)‚ it has no substantial atmosphere. Its extremely thin atmosphere mostly consists of a small amount of helium and traces of sodium‚ potassium‚ and oxygen. These gases derive from the solar wind‚ radioactive decay‚ meteor impacts‚ and breakdown of Mercury’s crust. Mercury’s atmosphere is not stable and is constantly being refreshed because of its atoms escaping into space as a result of the planet’s heat. The earths atmosphere compared to mercury is much MUCH better in terms of protection
