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.

In the final part, Professor Al-Khalili uncovers tales of success and heartache in the story of chemists' battle to control and combine the elements, and build our modern world. He reveals the dramatic breakthroughs which harnessed their might to release almost unimaginable power, and he journeys to the centre of modern day alchemy, where scientists are attempting to command the extreme forces of nature and create brand new elements.

Foo Fighters commemorate their 20th anniversary by documenting the eight-city recording odyssey that produced their latest, and eighth, studio album. Foo Fighters founder Dave Grohl directs the series, which taps into the musical heritage and cultural fabric of eight cities: Chicago, Austin, Nashville, Los Angeles, Seattle, New Orleans, Washington D.C. and New York. The band based themselves at a legendary recording studio integral to the unique history and character of each location. One song was recorded in each city, and every track features local legends. Even the lyrics were developed in an experimental, unprecedented way: Grohl held off on writing them until the last day of each session, letting himself be inspired by the experiences, interviews and personalities that became part of the process. Foo Fighters Sonic Highways is, in Grohl’s words, “a love letter to the history of American music.” Each episode delves into the identity of each city -- showing how each region shaped these musicians in their formative years and, in turn, how they impacted the cultural fabric of their hometowns. Every artist who appears in the show, regardless of genre or locale, started as an average kid with universal dreams of making music and making it big. Grohl made his feature film directorial debut in 2013 with the universally acclaimed Grammy-winning Sound City, a celebration of the human element in the creation and recording of music. Foo Fighters have won 11 Grammy Awards, including four for Best Rock Album, more than any other band. Premiering on the eve of Foo Fighters’ 20th anniversary, Foo Fighters Sonic Highways aims to “give back” to the next generation of young musicians. As guitarist and singer Buddy Guy, an interviewee from the Chicago blues scene, explains, “Everything comes from what’s come before.”
In the first episode, Dave Grohl and friends discuss the rise of the famous Chicago music scene from the roots blues of Muddy Waters and Buddy Guy to the Rock and roll of Cheap Trick.

Curiosity over the man calling himself a messiah makes Waco the center of a media circus. FBI negotiation and rescue teams clash over the use of force. The negotiating team established contact with Koresh inside the compound.
Communication over the next 51 days included telephone exchanges with various FBI negotiators. Koresh himself had been seriously injured by a gunshot. As the standoff continued, he and his closest male associates negotiated delays, so that he could possibly write religious documents, which he said he needed to complete before his surrender. Koresh's conversations with the negotiators were dense and they also included biblical imagery. The FBI negotiators treated the situation as a hostage crisis.

Today, the topic of climate change is a major part of daily life, yet 40 years ago it was virtually unheard of. Since then, Horizon have followed scientists as they have tried to unpick how the climate works and whether it is changing. Dr Helen Czerski delves into this unique archive to chart the transformation of a little-known theory into one of the greatest scientific undertakings in history. It has been a constantly surprising journey of discovery that has revolutionised our understanding of climate, and seen scientists face unprecedented controversy and criticism.
