Right, science is perfect and has a zero failure rate that is why cancer and cardiovascular disease are such big killers... 
LAWS of Science my friend are irrefutable. Scientific Law: This is a statement of fact meant to explain, in concise terms, an action or set of actions. It is generally accepted to be true and univseral, and can sometimes be expressed in terms of a single mathematical equation. Scientific laws are similar to mathematical postulates. They don’t really need any complex external proofs; they are accepted at face value based upon the fact that they have always been observed to be true.
Some scientific laws, or laws of nature, include the law of gravity, the law of thermodynamics, and Hook’s law of elasticity.
Physical laws are:
True (a.k.a. valid). By definition, there have never been repeatable contradicting observations.
Universal. They appear to apply everywhere in the universe. (Davies)
Simple. They are typically expressed in terms of a single mathematical equation. (Davies)
Absolute. Nothing in the universe appears to affect them. (Davies)
Stable. Unchanged since first discovered (although they may have been shown to be approximations of more accurate laws—see "Laws as approximations" below),
Eternal. they appear unchanged since the beginning of the universe (according to observations). It is thus presumed that they will remain unchanged in the future. (Davies)
Omnipotent. Everything in the universe apparently must comply with them (according to observations). (Davies)
Generally conservative of quantity. (Feynman)
Often expressions of existing homogeneities (symmetries) of space and time. (Feynman)
Typically theoretically reversible in time (if non-quantum), although time itself is irreversible. (Feynman)
