Професор Марк Стадтерр описує кровопролитну історію яка показує, чому важливо мати фундаментальні знання свого фаху і все тестувати. Американська ракетна батарея "Патріот" не змогла ефективно перехоплювати ракети під час війни в Перській затоці через неправильну арифметику з рухомою комою, внаслідок якої накопичувалася похибка під час відстеження цілі.
