Yes!! at the beginning of doing a project, you may need basic but important information about the project. Usually, books or literature reviews will provide this information for us. These books and literature may not be as fancy as story books or fictions, but they are important for several reasons: 1) knowledge that have been built up from previous efforts; 2) methods that succeed or fail to look for the answer and 3) materials and equipment that are necessary and robust to obtain data.
