Colored bismuth crystals, bright copper, silicon circuits, and more shine in our new exhibit celebrating 2019: The International Year of the Periodic Table! One hundred and fifty years ago, Dmitri Mendeleev published a draft of the first Periodic Table. Mendeleev also wrote “Knowing how contented, free and joyful is life in the realms of science, one fervently wishes that many would enter their portals” in his text Principles of Chemistry. Enter the portal to the Sciences Library to test your knowledge of the elements present in household items, to view our humorous periodic tables, and to see several elements in their pure form! Thank you to Dr. Lou Messerle for loaning us his collection of element samples!
