Einstein has problems: his mother thinks his head is too big; his family calls him dopey; his teachers find him frustrating. At the same time, he\u2019s forging an education of his own &#8211; he\u2019s fascinated by a compass; he spends hours building a 14-story house of cards; he teaches himself geometry with the help of a friendly medical student \u2013 and ultimately his oddness is spectacularly vindicated.
