Advertisement | The APS Science Trust Project was born out of member-demand to address misinformation about science, which has been increasing due to the broad accessibility of various streams of communication. This free virtual workshop, held on 4 consecutive Tuesdays, starting on November 29, 1:00 - 3:00 p.m. ET, via Zoom, will focus on climate change misinformation, but the skills and methods are appropriate for addressing a wide range of misinformation topics. Register now » | | | | | Advertisement | Build your on-campus physics community with help from a Women in Physics Group Grant. The APS Committee on the Status of Women in Physics (CSWP) is now accepting proposals from undergraduate and graduate students who are interested in creating new WiP groups or enhancing existing ones. The deadline for proposals is November 21. Learn more » | | | | | | Not an APS member?
