Golden Gate Bridge Physics n Mechanics n n n n Kinematics (motion) Statics, Dynamics (forces) Electricity Magnetism Waves Optics (geometric optics) Nuclear Physics (Modern Physics)
Physics n n The most basic science. The foundation of other sciences n n What? Why? How? When?
Aristotle (Greek 4 th Century BC) n n Logic Studied motion n n Natural and violent motion 4 elements: earth, water, air, fire Geocentric view Aristarchos(310 -230 BC), disagreed and believed in heliocentric view.
Democritus n Greek who devised the first atomic theory.
Galileo Galilei (1564 AD) n n n Father of the scientific method (along with the Englishman Francis Bacon 1500’s). Studied motion. Agreed with the Greek Aristarchos and Polish Copernicus (1473 -1543) on heliocentric view point. This lead to his house arrest.
Isaac Newton n English (1642 -1727) related force and motion and studied light.
A Glance at Some Scientists who Studied Electricity and Magnetism n n American Benjamin Franklin (17061790), experimented with electricity. Michael Faraday (1791 -1867), English with a grammar school education, found that a moving magnet induces electric current to flow.
The BIG Guy n n Albert Einstein (1879 -1955) Relativity: there is no absolute frame of reference that is at rest. Photoelectric effect (Light is quantized) (Nobel Prize) Related mass and energy E=mc 2
The Scientific Method n Steps followed during scientific investigations.
Scientific Method n n Recognize a problem Hypothesis- educated guess, testable n n When tested and confirmed becomes a law Observation -measurement, data collection (experiment) Theory – information including tested hypothesis Conclusion
Law or Principle n n A hypothesis that has been repeatedly tested and not contradicted. Laws change or are abandoned when contradicted.
Scientific Fact n n Observation May change
Science and Technology n n Science Pure Technology Applied
Math and Units n n Math- the language of Physics Units SI – International System n Basic Units n n n MKS Meter m Mass kg Time s National Bureau of Standards Prefixes
