Your lecture tonight, the “Unweaving Star Rainbows”, at the WOLAS Meeting in Harrow was most enlightening. The subject of Spectroscopy has always seemed dry to me (though necessary) so I have never taken the trouble to understand it. You brought life to it and your relaxed style was refreshing. I really enjoyed the broad content that included some historical breakthroughs, past giant scientists, the theory and it’s wonderfully staggering applications in astronomy. Very beautiful – thank you. Hope to hear you again soon, Best wishes. (Operations Manager by profession, enjoy science and a learning enthusiast)
