Many have asked the question: "How do we understand the world around us?" Truly, it is a question that has animated discussion from Beijing to Bogota over the millennia, and it's one that motivates Melvyn Bragg, host of the BBC program "In Our Time". Drawing on guests from around the world, Bragg takes on science, culture, religion, philosophy, and history. Visitors can click on the "Explore Archive" area to travel through past programs, organized by theme. The "Science Archive" section alone is a real triumph, and with programs like "Neuroscience: Does the brain rule the mind?" and "The Multiverse", a group of friends could start their own mini-salon of ideas around the computer. Moving on, visitors can also sign up to receive Bragg's online newsletter and subscribe to the program's podcast. Finally, visitors can also throw their own three cents into the ring by offering their own commentaries via the "Have Your Say" comment form.
