He was a great applied scientist and we owe much of our modern domestic technology to him: the kitchen range, double boiler, layered clothing and thermal underwear, steam heating,…. He was the first person to clearly understand all the modes of heat transfer. He was a public benefactor, initiated poor houses in many European cities, and he founded the Royal Institution in London which supported the research of Michael Faraday His career was a series of rags to riches. He would be better remembered if it were not for a character flaw: he antagonized everyone he dealt with to such a degree that he had to flee the country time and again.|[[https://youtu.be/Xnsh3_860TY|watch the presentation]]|<color #bdbdbd>41</color>|

Blind Bombing has a warm sensitive side, in that Norman Fine’s uncle (Stanley) brought the first production model of the new airborne radar system to Europe permitting allied bombers to destroy factories supplying the German forces that were usually obscured by overcast weather".|[[https://youtu.be/Ns883ab0vxM|watch the presentation]] {{:lctg:20200909_blind_bombing.pdf|slides}} |<color #bdbdbd>30</color>|

|Sept 23, 2020|**The future of music – production and delivery** by Charles J Holbrow (CJH). What can we learn about the future or music and music technology by looking at the past? I will present examples that illustrate the evolution of musical ideas and technologies from their conception to how they have influenced and continue to influence popular music today. I will describe how popular music is created today and review some research-stage music production technologies that aim to influence the current music production paradigms. As part of my PhD studies at the MIT Media Lab, I am developing software to enable a new kind of online musical collaboration and distribution. I will conclude by showing you an early example of this software \\ Who is CJH? His early education was in Germany. His high school was the Sudbury Valley School, an alternative school in Sudbury, MA. After a year at Middlesex Community College, he transferred to UMass Lowell where he majored in sound recording technology and performance (piano). Following jobs developing software for games, he took up an internship at MIT's Opera of the Future program with noted composer Prof. Tod Machover. Subsequently, CJH was admitted into MIT's Media Arts and Sciences program from which he expects soon to receive a Ph.D. He is Charlie Holbrow's grandson. \\ [[https://web.media.mit.edu/~holbrow/timelines/|The Media Timeline]]: Use mouse to zoom in/out; on Apple trackpad, two-finger up/down gesture to zoom; click and drag to pan the view.|[[https://youtu.be/FxrC_Kvt-zM|watch the presentation]] {{:lctg:20200923_future_of_music_cjholbrow.pdf|slides}} |<color #bdbdbd>40</color>|
