Engineering is the science of designing and building things. A philosophy of engineering is a way of thinking about how to design and build things in the most effective and ethical way possible. It involves finding out what people need, using science and math to create something that works for them, making sure it works safely and without causing harm, and considering the impact of what you create on the environment. Engineers need to think about how their creations can be used in the best way possible and how they could potentially create harm if not used responsibly.
