This track highlights the fantastic scientific applications that the SciPy community creates with the tools we collectively make. Talk proposals to this track should be stories of how using the Scientific Python ecosystem the speakers were able to overcome challenges, create new collaborations, reduce the time to scientific insight, and share their results in ways not previously possible. Proposals should focus on novel applications and problems, and be of broad interest to the conference, but should not shy away from explaining the scientific nuances that make the story in the proposal exciting.
