Study calculus, the first step is to understand that the "limit" the necessity of introducing: because, the concept of algebra is people are familiar with, but, algebra is unable to process the concept of "unlimited". So in order to use algebraic processing to represent infinite quantities, the concept of "limit" is constructed. In the definition of "limit", we can see that this concept bypasses the problem of dividing a number by 0, and introduces a process with any small amount. Is to say, the divisor is not zero, so meaningful, at the same time, this process can take any small small, as long as meet the Δ range, less than the arbitrary small, we can say he limit to the number, you can think it is opportunistic, however, his practical proof, such a definition is more perfect, the possibility of giving the correct inference. The concept is successful The permanity of time makes movement spatially oriented. Direction is spiritual content rather than the real content, because space motion direction is to form a certain period of time, make the starting position spirit record after compared with the current reality location to determine the current spatial direction. In contrast, spatial orientation is a reality because it has nothing to do with the time period. It was within the '70s and '80s that the Japanese began implementing technologies in diamond cutting. To help them to measure the quality of diamond cuts, they created special view-scope which they known as the FireScope. When viewing a diamond ring with the scope one surely could determine the hearth, or optical performance, in the diamond.
