Comments about "Testability" in Wikipedia

This document contains comments about the article Testability in Wikipedia
In the last paragraph I explain my own opinion.



The article starts with the following sentence.
Testability, a property applying to an empirical hypothesis, involves two components:
  • The logical property that is variously described as contingency, defeasibility, or falsifiability, which means that counterexamples to the hypothesis are logically possible.
  • The practical feasibility of observing a reproducible series of such counterexamples if they do exist.
This definition is not very clear.
In short, a hypothesis is testable if there is some real hope of deciding whether it is true or false of real experience.
This sentence is too vaque.
A hypothesis is testable if it can be established by experiment if the hypothesis is true or false.

Reflection 1 - Testability

Testability, the activity to perform experiments to decide if a recipe, hypothesis, medicin or theory is right wrong is very important in science.
When you consider physical sciences, medicin and chemistry most of these tests are performed in a laboratory. Astronomy, Cosmology and Astro physics is an area where it is very difficult to perform experiments. In many cases the only thing we can is to observe similar processes (events) and try by reasoning to unravel the laws that describe these processes (events).
Newton's Law is discovered using that method. What makes this law so strong is that part of the hypothesis on which this law is based can be actualy be tested in a laboratory. The Inflation theory describes an extra burst in expansion direct after the Big Bang. To demonstrate that is much more difficult.
