Professor Marcus du Sautoy explores why we are driven to measure and quantify the world around us and why we have reduced the universe to just a handful of fundamental units of measurement. He tells the story of the metre and the second - how an astonishing journey across revolutionary France gave birth to the metre, and how scientists today are continuing to redefine the measurement of time and length, with extraordinary results.

Five times, the Earth has faced apocalyptic events. Cataclysms that have swept away all life forms, or almost. Each time, a handful of species has survived, establishing a new world. What did these prehistoric worlds look like? What catastrophes led to their disappearance? How did our distant ancestors manage to survive the five mass extinctions that the Earth has suffered, finally giving rise to the world we know today?
Combining CGI of ancient animal and plant life, VFX and filming, 'Prehistoric Worlds' looks back at the five mass extinctions of life on Earth that allowed the advent of the human race. On the brink of a sixth mass extinction that the scientific community considers imminent – this time caused by mankind – this film gives us an interesting and powerful look at Man's existence on the scale of the history of our planet.

In the 1960s and 1970s a generation of Mexican Americans, frustrated by persistent discrimination and poverty, find a new way forward, through social action and the building of a new "Chicano" identity. The movement is ignited when farm workers in the fields of California, led by Cesar Chavez and Dolores Huerta, march on Sacramento for equal pay and humane working conditions. Through plays, poetry and film, Luis Valdez and activist Corky Gonzalez create a new appreciation of the long history of Mexicans in the South West and the Mestizo roots of Mexican Americans. In Los Angeles, Sal Castro, a schoolteacher, leads the largest high school student walkout in American history, demanding that Chicano students be given the same educational opportunities as Anglos. In Texas, activists such as Jose Angel Gutierrez, create a new political party and change the rules of the electoral game. By the end of the 1970s Chicanos activism and identity have transformed what it means to be an American. Chicano and Latino studies are incorporated into school curriculum; Latinos are included in the political process.

Follows actor, model, and icon Brooke Shields as she becomes a woman who discovers her power after being a sexualized young girl. She shows the dangers and triumphs of gaining agency in a hostile world.
In the first episode, from young girl to Princeton graduate, we explore Brooke’s extraordinary childhood and her complex relationship with mother/manager Teri.

Now, the most famous woman to graduate college finds her voice, but when she tries to use it, a toxic culture that perpetuates misogyny will do anything to shut her up. Brooke Shields talked about her life and career. There was a time when she was a household name, a cultural phenomenon. Shields didn’t need much of an introduction. Most often, her starring role in the 1980s film 'Blue Lagoon' or her Calvin Klein ads are enough.

Documentary about progressive music and the generation of bands that were involved, from the international success stories of Yes, Genesis, ELP, King Crimson and Jethro Tull to the trials and tribulations of lesser-known bands such as Caravan and Egg. The film is structured in three parts, charting the birth, rise and decline of a movement famed for complex musical structures, weird time signatures, technical virtuosity and strange, and quintessentially English, literary influences.
It looks at the psychedelic pop scene that gave birth to progressive rock in the late 1960s, the golden age of progressive music in the early 1970s, complete with drum solos and gatefold record sleeves, and the over-ambition, commercialisation and eventual fall from grace of this rarefied musical experiment at the hands of punk in 1977. Contributors include Robert Wyatt, Mike Oldfield, Pete Sinfield, Rick Wakeman, Phil Collins, Arthur Brown, Carl Palmer and Ian Anderson.
