WHAT IS THE THEORY OF RELATIVITY

CHAPTER-1 THE RELATIVITY WE ARE USED TO Does Every Assertion Make Sense? Obviously not. Even if we take some words and link them together in strict accordance with the rules of grammar, the result may be complete nonsense. There is no sense what-ever, for example, in the assertion that "water is triangu-lar". However, not all nonsense is so obvious. All too often an assertion which appears quite reasonable at first glance turns out to be absolute nonsense under closer scrutiny. Right or Left? On what side of the street-right or left is the house? You cannot possibly answer this question offhand. If you go from the bridge towards the wood, it will be on your left-hand side, and if you go in the opposite direc-tion, it will be on your right. Speaking of the left- or right-hand side of a street you must mention the relative direc-tion. There is sense in speaking of the right bank of a river, because its current determines the direction. We can sim-ilarly say that a motor car drives along the right-hand side of the roadway, because the flow of traffic indicates the relative direction. The notions "right" and "left" are therefore relative and make sense only when a direction is given to guide us. Is It Day or Night Now? d to elyen as musi The answer depends on the location. When it is day in Moscow, it is night in Vladivostok. There is no paradox
