MAS November Meeting

The Chemistry of the Universe

Susanna Widicus Weaver, The Chemistry of the Universe

Summary: Molecules make up the world around us and serve as the building blocks to life as we know it on Earth. The questions remain as to how these molecules form and are incorporated into planets, and whether life might form elsewhere in the universe. Astrochemists study the chemistry of space and the evolution of molecules as stars and planets form. In this talk, I will overview my astrochemistry research program that incorporates laboratory spectroscopy, observational astronomy, and astrochemical modeling to decipher the chemistry that might lead to life in the universe.

Susanna Widicus Weaver, Vozza Professor of Chemistry and Astronomy at the University of Wisconsin is an expert in prebiotic astrochemistry...

MAS August Monthly Meeting

Stellar spectroscopy and the formation of the chemical elements

Jim Lawler

Dr. Jim Lawler, UW Madison Dept of Physics, the Arthur and Aurelia Schawlow Professorship

I will talk about how we measure spontaneous decay rates between two energy levels of an atom or ion, how stars produce spectra, and links between basic spectroscopy (like my group’s activities) and astronomy. Nearly everything humanity knows, or may every learn, about the detailed physics and chemistry of the remote Universe is from spectroscopy. I will mention the importance of quantization and the future of the quantum internet if time allows.

Before retiring in May of this year, Jim Lawler was the Arthur and Aurelia Schawlow Professor of Physics at the UW Madison...
