The Physics Teacher
Volume 59 Issue 9
This month's cover presents an arresting wintry scene, quietly inviting the viewer to ponder these icy stalactites and the role of the weakest fundamental force in their creation. “Gravity in Icicles” was submitted by Declan Reed St. John from Minnetonka High School in Minnetonka, MN, and was selected as one of the top 100 photographs in the 2019 AAPT High School Physics Photo Contest. His physics teacher was Kim Hoehne. PS: Note the air bubbles inside the icicles!
