Hello! It's been a while, but I'm back with some updates and with a new bonus episode for you all :)

I was happy to be invited back to the Intelligent Speech podcasting conference, held on  June 25, 2022. I took part in the STEM roundtable discussion and also presented a talk entitled "You Are My Sun-Line: Solar Spectroscopy and an Early Spectroscope". I discuss the history of solar spectroscopy, from rainbows to Newton to intergalactic stellar analysis, as well as two 19th century spectroscopes held by the Whipple Museum of the History of Science at the University of Cambridge.

How do we know what stars are made of? What have lines got to do with it? This talk will answer these questions and more, with the help of a 19th century spectroscope (or two!).

You can watch the video recording on the Intelligent Speech Conference YouTube channel.
