When the first people looked up at the sky and saw the Sun, the Moon, the stars and the five known planets, they invented myths to explain their motion. But myths could only get us so far. While the ancient Egyptians were great technologists, it was the Greeks who took this business of measuring the Earth and finding out its shape seriously. Listen as I take you on a journey of discovery and thought all for the love of science.

Each episode requires hours upon hours of research. This 17-minute episode may not seem like it, but trust me, it does take a while. With that in mind, at first my frequency of uploads will be sporadic, but soon I'll get a regular schedule going with longer episodes and the promised Patreon page. For now, could you please subscribe and share with others? Thank you.
