 | Theories  | Explains the connections between things in the world |
 | Hypothesis (Icel. tilgáta)  | A prediction about the relationship between a limited set of phenomena, as explained by a particular theory. |
-| Support from evidence  | The strongest form of evidence is rigorous hypothesis testing using scientific experimentation: clearly thought-out tests of the claims that naturally fall out of the Theory to be tested. It helps if the hypotheses concern unexpected results. |

-====Rudolf Carnap: Observables and Non-Observables====
+====Theory and Empiricism====
-| "observable"  |    |
+| "Observable"      | Philosopher: what you can observe with your senses. Scientist: what you can measure   |
-| "non-observable"  |    |
+| "Non-observable"  | hypothetical concept (that may become observable at some point, in the scientists sense).   |
+| Empirical laws    | Rule that relate two or more observables. Example: Color wheel artithmetic - yellow+blue=green.   |
+| Theoretical laws  | Rules that deal with non-observables.  |
+| Rule <-->  law  | Law: Rule that has become established (through experiment).  |
+| Empirical laws <--> facts  | Empirical laws relate facts about observables.  |
+| Empirical law <--> Theoretical law  | Similar to empirical <--> facts relation.  |
+| Theoretical example  | The concept of "atom" would never arise out of observation.  |
+| Empirical example  | The concept of the "heat expands metal" can be measured on observables.  |
+| Theoretical laws produce empirical laws  | E.g. Theory of Relativity predicts bent light in gravitational fields.  |
+| Correspondence rules  | Relate theoretical laws with empirical laws and observables.  |

+====Will Science Ever Be Done?====
+| The Big Question  | Will science ever be "finished"? Will it ever have explained reality to such an extent as we can say "we now have a complete theoretical framework where every theory has been unified (explainable in a single overall theory), everything is understood and everything can be predicted."   |
+| Answer 1   | It will not finish because, at the current speed of scientific inquiry, the human race will perish before all things in the universe have been fitted into a complete model/Theory of All.  |
+| Answer 2   | It is already "finished", in that its uncovering of big theories is slowing down, inevitably - for all practical purposes - grinding to a halt in the next 100 years.  |
+| Answer 3   | We will build intelligent machines that can do science at 10k times the speed of humans. Hence we might be done with theoretizing the universe within humanities timeframe.  |
