It is very interesting question for me but it isn't simple for my english. I would choose one of science has to do with practical physics, math. astronomy, astrophysics. There are a lot of topics which practical physics is studying and trying to solve. For examples, the creation of new ecological materials. It may sound boring for somebody. But I think it is a very interesting and imaginative process. Scientists every day try to create new materials. Often we don't remark this even but new materials and things made of new materials become to be habitual for us. For example, the invention of "Pure Pack" packaging for milk. This thing is very habitual, very routine and not interesting for us. We use this thing and dump into garbage. This packaging looks to be very simple. But this packaging consists of very interesting material and has a very interesting structure and a construction. This packaging is relatively cheap, ecological, comfortable for consumers and for producer which pour a milk into these packaging. It was a very smart invention. I have written a very simple example from our every day's Life. But there are more interesting examples of application of new materials in elecntronic technologies and space industry. And I could dedicate myself to creation of new materials :)))
