NUM
Engineering Education Should Be Accessible to All!
At Num Engineering, a non-profit organization dedicated to advancing engineering knowledge, our mission is to break down barriers to education. We believe that access to knowledge should be free and unrestricted for everyone.
Num Engineering is committed to providing open and equitable access to engineering resources, learning materials, and educational support. Our project is fully compliant with legal regulations, as there are no laws that should prevent anyone from accessing knowledge.
We are deeply concerned about the current state of academic help and tutoring services within the field of engineering. Many of these services impose financial barriers, limiting access to valuable educational resources behind paywalls. Num Engineering stands against such practices, advocating for equal access to engineering education and information for all."
