Textbook publishers apparently think the periodic table is just a suggestion. "Published half an hour after the Big Bang" is the most accurate description of every chemistry textbook I've ever been assigned. Nothing like paying $300 for a book that's missing elements discovered during the Mesozoic era. Fun fact: since 1995, we've added 15 new elements to the table, and somehow my professor's lecture notes haven't noticed.
