    Abstract: From Galileo telescope designed in 1609 to the recent advanced astronomical telescope, telescopes always help people in coping with different problem. The relation between the parameters of telescope and its performance has been a hot topic for a long time. In this paper, we have designed a simple single-lens telescope based on the Problem No. 3 in... Show More

    Abstract: The occurrence of prevalent phenomena is an almost unclear but interesting subject for us. Here we have constructed a dual model of information fields originated from the news media and showed that the quasi-cyclic appearance of prevalence can be explained by such a model. The homogeneous field of information around us was assumed, which is compose... Show More
