We have an interesting interview today with Gideon Shelach-Lavi. He's part of a team that is researching walls in Mongolia. These walls span a large distance and range of time and some are contemporaneous with the Great Wall. Gideon talks about the tech they used to map and analyze the miles of walls they've found and what's next for them.
