When most of us hear "scientific research", it conjures the image of serious men and women in meticulous labs using carefully prescribed methods to achieve rather predictable outcomes. We have an expectation that science is calculated and controlled. Yet some of the most influential scientific discoveries have been made entirely by accident. Does chance work alone or are other phenomenons at play?

In part two, Professor Al-Khalili looks at the 19th century chemists who struggled to impose an order on the apparently random world of the elements. From working out how many there were to discovering their unique relationships with each other, the early scientists' bid to decode the hidden order of the elements was driven by false starts and bitter disputes. But ultimately the quest would lead to one of chemistry's most beautiful intellectual creations - the periodic table.
