["Scientific research doesn't care about the clumsiness or grace of the method, as long as it achieves the purpose of solving the problem.", 'Opportunism in scientific research makes beautiful methods never found.', 'The purpose of scientific research is to solve problems.', 'Graceful methods are not the goal of scientific research.']
