Physics had completed its works...until relativity and quantum physics came along.
Uncertainty principle made it impossible to know truth through observation because the experiments actually helped invent reality.
Philosophy of science: Verification (verify a theory in terms of proof positive) and falsification (prove the theory is not true) were both fallacious. Verification is impossible because there are always rival theories that could explain the data. Falsification requires the revision of theories proven false and the re-testing. Verisimilitude (process of revising and re-testing theories to improve them) can never put theories beyond criticism and can never fully-prove them. Science can therefore never reach truth.
Why study science?
1. To be able to debate in the language of sicence
2. Scientific reports, dispite their short-comings, are still in demand
3. The pursuit of science (understand phenomena, discovering relationships, seeking better treatments, etc.) is a valuable pursuit
4. We can examine the strengths and weaknesses of the approach
