Science is respectful discard to politic The International Nanotechnology Festival and Exhibition in Iran has started eight years ago. Sanctions limited science and pushed it to limit here. We had to move and find a way in an isolated atmosphere. Science has lead in a sheltered life. It is respectful and it doesn't care to politics despite it got involved at that time. Actually scientific researches were victims of political infightings! Now this movement has been grown up and some flourishing companies introduce their productions in competition every year. I already knew several of them in collaboration with my previous university and some other last five years in order of ordering some equipments for Semiconductor Lab. It is extended society now, so we can put something on demand with varieties of selection. Actually they are competitors and we are audiences. Every year I come to see how much they have developed? I would be happy with their progress.
