Abstract This paper describes two examples of teaching situations in which the idea of infinity arises, and supports the conclusion that infinity is not a physical reality but a very powerful and useful mathematical device which facilitates modelling and the solution of problems in physics.

Physics teaching materials for Senior High School that supporting the development of human resources that is able to adapt to any changes, to solve complex problems, creative thinking and familiar with information technology has not been widely available in senior high schools in West Sumatra. Based on the above, research that aims to determine the effectiveness of the use of Physics teaching materials that integrates Mathematics, Science, Technology, natural disasters, and the noble character (MSTBK) on WEB for Senior High School grade XI and to determine the effect of the use of teaching materials MSTBK on the learning outcomes of high school students in class XI. The quasi-experiment design research was comparing the learning outcome before and after the state of the object being treated. The treatments were using physics teaching materials that developed for teaching learning in Senior High School grade XI. The experiment was conducted at five senior high schools in West Sumatra were divided into 3 levels. The data were analyzed by using a statistical product moment and Anova. The research showed that the physics teaching materials that developed are effectively to improve student learning outcomes in Senior High School grade XI in West Sumatera with a correlation coefficient (r_xy) = 0. 31. Levene Statistic showed the average of the learning outcomes of high school students in grade XI was different, but yet rules Tukey HSD and Bonferroni statistics show that there are not significantly of 0.05 at a significance level in West Sumatra

The epilogue synthesizes the insights gained from the preceding chapters. The observation that non-representational dances trigger interpretations in the internal audiences highlights at once the capability of dance to go beyond representation and the need to find meaning in it. Just as the dancers are affected by the physical reality of their performance, so the spectators too are affected by the physical presence of the dancers. Dance is performative and dynamic, and its way to cognition and action is experience. Dance reconciles opposites by encapsulating vitality and disruption, rational patterns and sensory experience, presence and transience, active and passive. The mimesis of dance interacts in many ways with the pragmatic contexts of its performance, making it a powerful cultural force.
