Паркетчику необходимо уложить пол ровными квадратами. Он вырезал квадраты, а затем проверял свою работу, сравнивая длины всех их сторон. Мастер считал  квдраты вырезанными верно, если все четыре стороны были равны.

Надежна ли такая проверка?

Великий немецкий композитор Людвиг ван Бетховен был глухим последние 30 лет жизни. Тем не менее, он слышал музыку внутренним ухом, зажимая трость зубами и упираясь ей в рояль. Именно в этот период жизни он создал одно за другим свои самые известные во всём мире произведения.
