( CNN) I was proud to join thousands of concerned citizens, scientists and engineers in Saturday’s March for Science. With more than 600 marches taking place around the world, we communicated that science is political , not partisan, and science should shape our policies.

Although it is the signifies by which humankind discovers objective truths in nature, science is and has always been political. Article I, Section 8 of the US Constitution refers to promoting “the progress of science and useful arts” to motivate innovators, stimulate economics and establish simply statutes.

The US has become the most powerful nation on Earth and among the greatest in history, because it has long respected and promoted science. Countless policies, from military deployments to regulations that control the formula of a shampoo, are based on science.
