Science is a like a lego-brick factory of basic truths. It tries to create items that we can fall back on and rely on to be true. We can then go on and use these items or principles to build objects of fantasy on solid foundations and test their strength — and they will always be stronger than any object built on unproven and weak foundations.

If you only learn two things in life, it should be how to contribute to creating these first principles and how to build on top of them.
