The current study aims to describe meaningful, powerful and effective tool, used to encourage technical students to apply mind mapping techniques in the language classroom. For this purpose, we overview the previous and the present studies, concerning the problem and describe the implementation of mind mapping techniques in the learning process. The results of this study showed that mind maps help students solve problems, brainstorm creative ideas, remember new vocabulary, take notes, enhance their reading skills, organize the tasks and prepare presentations. This study concludes that mind mapping technique invented in the XX century is considered to be up-to-date, creative, useful and available tool for students, educators and researchers

In this study positive and negative influence of the feedback have been examined. A feedback principle in the alternating current amplifier and in the speed regulator of the turbine rotation was described. The main conclusion of the positive and negative effect was obtained. Negative feedback worsens the properties of an object, reducing a strengthening factor, delaying regulatory action. Positive feedback considerably raises device work stability. This research will enable to identify the importance and effectiveness of the feedback principle in science and technics.
