The second Monday of each month, Music Box Supper Club hosts Science Cafe, an informal lecture series that brings scientists from throughout the region to the club so they can talk about science topics. Tonight at 7, Andrea Waksmunski and Jonathan Haines from the Department of Population and Quantitative Health Sciences at Case Western Reserve University will speak about electric propulsion as an emerging new paradigm for space propulsion. Admission is free. (Niesel)
