In December 2017 I had the opportunity to spend a few days on board the Royal Navy’s HMS Enterprise on her trip from Limassol, Cyprus to Valetta, Malta. HMS Enterprise is a survey ship, her primary task is to map the sea floor using sonar and feed the data into civilian and military maps. In this detailed episode, we chat about the ship, its mission, the survey equipment, the technical aspects of the propulsion and systems, plus about life on board a ship and nautical issues in general.

Conlangers are people who design human languages, either just for fun or for use in works of fiction, often TV series or movies. My guest, David Peterson, has designed several languages, including the the Dothraki language featured prominently in Game Of Thrones. In this episode we use Dothraki (and English, and a bit of German) to introduce the basics of linguistics, i.e., the science behind natural (and in this case, designed) languages. We also discuss a few specific of Dothraki, and how it gets used in Game Of Thrones.
