However some people describe science as part of theories with their philosophical basis, and engineering as processing means of the theories or their validation by experimental setups. While other people define engineering as technical methods not so strong as science with its philosophy basis. Others identify engineering science as the mother of sciences since most discoveries or inventions were firstly based on processing materials, tools and methods who were later refined by mathematics.
