1. First of all I think about such basical things as fire, wheels, paper, money - what would our life be without this things? Thay are really breakthroughs, because have changed the life of the mankind.

4. Bioengineering, discoveries in medicine, human-like robots, Curiosity rover. All these marvels of the modern science are discovering and improving the life of a man like biological being and the life of a man as a researcher. 
5. Yes, of course. Charles Darwin, an outstanding British scientist, the father of evolution theory; Dmitry Mendeleev, Russian god of chemistry, who has formulated the periodic law; Nikola Tesla,  great American inventor and theoretician of the alternating current. 
6. I think that high technologies are already in use, and new technologies are in testing.

7. The work of a scientist is a routine with many experiments to be patiently carried out again and again, so it might seem dull. But of course it is so exiting to overcome nature or receive the result desired.

Then he tries to solve it, or realize and formulate scientific laws, or explain the laws of nature and space.  For example, Russian linguist Andrey Zaliznyak has carried out many archaeological expeditions to study the birch scrolls of Novgorod, and has made important linguistic discoveries.
