"The Art of Science" Trivia Game ($49.99)
It's a science smackdown in The Art of Science, a deliberately hard trivia game available from Think Geek. Questions cover five technical fields—math, biology, physics, chemistry and technology—as well as a "miscellaneous" category. With 330 cards featuring queries such as "What is the antiparticle of an electron called?" you will have no shortage of brain-stretchers to test your science-geek mettle.
