Friday, July 5 is LGBTQ STEM Day, an initiative launched to celebrate the contributions the LGBTQ+ community has made in science, technology, engineering and math.

“LGBTQ+ people in science, technology, engineering, and maths (STEM) continue to struggle to openly be themselves,” reads a statement on the Pride In Stem website.

“We believe that a day of recognition goes a long way in helping raise awareness and increase support. It is an important component of the global push to increase diversity and inclusion in STEM.”
