Very simple: Try testing: "The laws of science are universally rational and applicable."
Science itself is based on the assumption that the universe is based on rational principles.
When you think about it, God alone could find such an assumption, or hypothesis, falsifiable.

Your quote is not a "scientific" truth in the usual sense, that is, it is not itself a law of science, but a statement about the laws of science. The laws themselves must be testable, and cannot be considered laws until they've "passed the test," so-to-speak.
If by "the laws of science" your quote means all those laws thus far discovered and tested, then your quote has been tested by means of testing every law it includes. If by, "the laws of science," your quote means all that have been discovered and proved, and all those not yet discoeverd, and all those still being tested," then your statement is not a truth of science, but a general descriptive concept about science, and does not come under the requrements of a scientific truth itself.
