For centuries, members of the B’doul Bedouin tribe lived in the caves around the ancient city of Petra, Jordan. Then, in the 1980s, the government forced the tribe to move in the name of preserving the geological site for tourists. But if the residents are forced to leave, and if their heritage has been permanently changed, then what exactly is being preserved? SHOW NOTES: Meet The Man Living in The Lost City Carved in Stone Jordan: Petra's tourism authority cracks down on Bedouin cave dwellers The tribes paying the brutal price of conservation “There is no future for Umm Sayhoun” Jordan’s Young Bedouins Are Documenting Their Traditions on TikTok Check out Sami's company Jordan Inspiration Tours Learn about your ad choices: dovetail.prx.org/ad-choices…

Precalc Problems Explained

Here we have basic angles in radians, and graphing the trig functions of these angles. These functions, with their ability to transform waves with different periods and amplitudes, can be used to mathematically express all sorts of waves we find in real life. These ideas are from Sections 4.1 to 4.6 of our Precalculus book by Larsen.…
