What’s the more interesting aspect of maps—their cosmological past or their technological future? Both, suggests the Ripley Center’s current exhibit, “The Power of Maps,” and co-curator Lucy Fellowes apparently agrees. Fellowes, who works at the Smithsonian’s New York outpost, the Cooper-Hewitt National Museum of Design, will discuss the literal and the fanciful, the ancient and the cutting-edge in a slide-illustrated lecture, “Seeing Space: The Design of Maps.” At 8 p.m. at the Museum of Natural History’s Carmichael Auditorium, 14th & Constitution Ave. NW. $11.
