Proceedings of WAC 2018 (hosted by the Sharpe Planetarium, Pink Palace Museum, Memphis Tennessee) are in the files below. The videos have been made much lower resolution that the original recordings, the intent being to mostly capture the audio of the presentations. On a computer or laptop, you can place the video and the separate file of slides side by side

and step through the slides as the video plays. For descriptions of the various sessions and presentations, refer to the program at the bottom.
