This month's cover is another astonishing photograph by Daniela Rapava, a delicate snowflake occupying an improbable perch. Dr. Rapava’s work has been featured on TPT covers and in Visual Physics in the past—see TPT issues from Nov. 2018, Dec. 2016, Oct. 2016, May 2015, and April 2015.using a Nikon D3200 digital camera equipped with a micro lens f=105 mm.

Since August 1, 2014, the submission process for articles for The Physics Teacher has required authors to submit their article and cover letter at this website:  Starting June 10, 2020, the submission process for articles for The Physics Teacher will change.   On or after June 10th, authors should submit their article and cover letter at this website:
