Albert Einstein developed a theory about the relationship of mass and energy. The formula, E=mc[2], is probably the most famous outcome from Einstein's special theory of relativity. Show your intelligence with our e=mc(2) lapel pin! Handcast in solid, lead-free pewter, each of our pins is an original three dimensional sculpture signed by the artist, Jim Clift. Handcrafted in our studio in Coventry, RI, our pins are 100% US made.
