Why is testing ideas an important part of all science and engineering practices

Scientists and engineers actively seek evidence to test their ideas — even if the test is difficult. The reason behind is the importance of asking questions based on observations to find more information about the natural effects and proposals. From there, it is ought to determine expected results based on testing, evidence resulting from that experiment will allow testers to find out the solution they are looking for.
