Science is not only defined as a technique. It's also defined as "a particular branch of knowledge", "systematic knowledge of the physical or material world gained through observation and experimentation", or "systematized knowledge in general" and those are just a couple definitions. Science is our knowledge of the truth of the way the world works. It is the truth, so far as we are aware, and all evidence says that we are correct. It's not just a method, and it's not just numbers and formulas. Science can also be soft, as in economics and psychology. It describes and analyses everything in our world, even our own actions, even our own emotions. Science is the way we work, the way the world works.
