The architect designed all of the most beautiful buildings in the city . He knows on physics , mathematics and chemistry. He must surely know what bricks to use , how much glass tile walls and the whole structure can withstand tremendous physical exertion . Look at him - as leaning working hard at the drawing board . It's all his world .Now he is developing a roll of drawing design. The light illuminates next to the complex mathematical calculation . It's a real Leonardo of our time. Could without him we live in this wonderful block? Rather, we have been trying mud hut .
