The smallest integer is \( \sqrt{141} - 1 \), but must be integer — contradiction.

["The Smallest Integer Equal to ( \sqrt{141} - 1 ): A Contradiction Explained", "At first glance, it seems simple: calculate ( \sqrt{141} - 1 ) and find the smallest integer that satisfies this equation — but a mathematical contradiction emerges when we demand both conditions.
