The perfect gift for the physicist (or lover of the Big Bang Theory): the periodic table of the elements notebook. Yes, THAT periodic table of the elements. All 118 of them. Each element gets its own page, complete with atomic number and symbol. The rest of the page is blank to record your thoughts, your day, your plans to take over the world. (Peacefully, and with love, of course.) The sleek matte black cover is minimalist and discreet, and the ink inside is a subtle steel gray. The 6" x 9" size is perfect to throw in your satchel or bag and it's light enough so it won't weigh you down.
