You have just three days left to submit those killer #histSTEM (that’s history of science, technology, engineering and medicine) posts for this months #62 edition of Giants Shoulders hosted by the one and only HPS Glonk (Dominic Berry).
Submission came be made direct to the Glonk or to me here at RM or to either of us on twitter (@HPSGlonk & @rmathematicus)
