Differences in size are often described as differences in order of magnitude close order of The blue whale weighs approximately 190,000 kilograms, while a plankton weighs just 0. However, 250 written in scientific notation is 2. Planck length; typical scale of hypothetical loop quantum gravity or size of a hypothetical string and of branes; according to string theory, lengths smaller than this do not make any physical sense. The order of magnitude of a number is the power of 10 that most closely approximates it. Scientists attempt to describe the world by formulating models, theories, and laws The adjective in the title of the book, order of magnitude, reflects our emphasis on approximation. 數量級（order of magnitude），又稱數量序 [1] 、量級、階值 [2] ，是對某個由上下文決定的參考值（通常為 10）取對數的近似值，代表數量的尺度或大小的級別。 Jul 16, 2020 · Order of Magnitude: The class of scale or magnitude of any amount, where each class contains values of a fixed ratio (most often 10) to the class preceding it.
