Euclid’s Axiomatic Method in Science • Logical procedure by which theories are deduced using logic from basic propositions (axioms) • Propositions are constructed from a few primitive terms • Terms may be defined arbitrarily or empirically • Science consists of a collection of arbitrary and empirical propositions and all the logically derived theories from those axioms
Problems with Axiomatic Method • Identification of primitive terms • Determination of fundamental axioms
Newton’s Scientific Assumption ALL OF THE UNIVERSE CAN BE EXPLAINED IN TERMS OF FORCES ALONE
Newton’s Empirical Scientific Method • Systematic observation of forces • Experiments with forces • Measurement of forces • Mathematical formulation of force laws • Determine additional phenomena implied by force law • Experimental testing of force laws and additional phenomena • Modification of force laws as required by experiment
MathematicsThe Primary Tool of Science • Enables an analysis of forces • Helps identify the primitives • Helps identify the causes of forces • Adds credibility to scientific theories
Newton’s Conditions for Physical Force • Direction of the force must be determined by some material body other than the one it is acting on • All aspects of the force’s magnitude must be given by a general force law that is dependent on the forces of action and reaction • Some of the physical quantities in a force law must pertain to the other body in a way that determines the direction of the force
Newton’s Conditions for Physical Force • The force law must hold for some forces that are indisputably real • If the forces acts on a macroscopic body, then it must be composed of forces acting on the microphysical parts of that body.
Newton’s Rules of Natural Philosophy • No more causes of phenomena are allowed than are true and sufficient to explain them • The same natural effects should always be assigned the same causes • The qualities of bodies within reach of our experiments are assumed to be universal qualities of all bodies • Propositions inferred by induction from experiment are to be considered as accurate or true until disproven or modified by other phenomena
Maxwell’s Axiomatic Method • Based on 4 empirical laws of electrodynamics • Based on point particle idealization • Based on logic to derive a more comprehensive theory
Photoelectric Effect Na Crystalline Metal Plate
Einstein’s Special Relativity Theory • Based on quanta from photoelectric experiment • Based on Michelson-Morley experiment
