in today's era with the development of technology, humans can create items needed for human survival. With technology, we need the knowledge to create this technology. Science can come from anywhere, like the story in the film "the boys who harnessed the wind" a child who uses a limited resource of knowledge to create useful technology.
Based on a true story, William Kamkwamba, a 13-year-old boy from South Africa, built a wind turbine to save his village in Malawi from hunger.
With William's shortcomings at that time he was dismissed from school, William with only a capital read only science books, and he made windmills with the help of electric power and bicycle dynamos.
William's school is arguably lacking in facilities, but only utilizes the library to gain knowledge and is relatively young, but he has ideas and makes innovations.
From here we learn that to create useful technology does not look at age, as long as we have the knowledge and persistence we can create useful technology.
