Answer:
It is important to learn about the work of previous scientists because through learning about their work and their mistakes, it will prevent us for making the same ones. Learning about what has already been discovered and what possibly went wrong in the past provides more of an opportunity for growth in the future. Also, we can get inspired by the work in the past because if we see what was possible back then, it will help us imagine what can be possible in the present and in the future.
