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.

Professor Mark Stadtherr told a bloody story about why it's important to learn basic computer science and test everything. American Patriot missile battery had failed to effectively intercept missiles during the Gulf War due to poor floating point arithmetic that accumulated error during target tracking.
I'm glad this problem got fixed before Patriot system has been deployed in Ukraine to protect
