Title: Robert Goddard on his Centennial Celebration of American Rocketry

In this presentation, Mr. Schindler will discuss the contributions of engineer, educator, and inventor Robert Goddard, creator of the world's first liquid-fueled rocket, which was successfully launched on March 16, 1926.

Kevin, a resident of Flagstaff for over three decades, has given more than 1,000 presentations and published nine books on the history of Flagstaff and northern Arizona, including “Lowell Observatory, Images of America.” He is the most recent recipient of the Copper Quill award, presented by the Flagstaff Friends of the Library for his contributions to the region.

Title: “The latest Hubble Tension: A History of the Expansion of the Universe”

Description: Cosmology as a science began about a hundred years ago, around the same time we realized that some spiral nebulae are entirely different galaxies. When able to measure their distances, we discovered that the universe is expanding. Over the next hundred years, our understanding of cosmology evolved as the distance ladder improved. Recently, however, as precision improved enough, the present local rate of expansion as measured directly differs significantly from that expected by our cosmological models. This latest tension either gives rise to the need to explore better cosmological models, or reconsider the precision of the distance ladder, or both.
