Through trial and error, he performed experiments involving the cross pollination of flowers to portray his theory that cross pollinated offspring would survive better than self-pollinators. He wrote a simple procedure and his methodology behind his theory. By proving it correct, other scientists are able to reciprocate the experiment and evolve from these findings. Nevertheless, science is unreliable and always changing based on the evolving world and knowledgable input from countless scientists. It is very debatable because there are areas within science which are difficult to qualify and quantify which makes it difficult to use and apply different techniques to find a solution. There are many variations of false adverting and forms of "pseudoscience" where unconfirmed claims are presented as scientific facts to prove a mysterious phenomena. Also, since experiments are performed by people there are problems with the observations of the work and is subject to a bias. .
More than science, math is viewed as a more concrete and reliable source of knowledge. Its basic functioning and application process makes the end result concrete and unquestionable. Although it may be arguable that math is not a science, the facts and processes seem similar. However, a majority of people believe math to be more reasonable because their are doubts in science. Math provides certainty and practical value that other subjects may not carry. It is also an important tool used in our everyday lives to evaluate solutions. For many adults, calculating taxes, finances, buying clothes, cars, etc., all require basic math skills. From a broader perspective, one may see these skills as "ingrained" into our mind because of its simplicity. Without these skills, many people would always need help and always find themselves in a difficult situation. In reality, these basic skills allow us to address bigger problems.
