Exam #1 is in class today.

Some example quesions:

• What is light made of?
• What is time dilation?
• What is momentum?
• What is four concepts did Einstein unify with General Relativity?
• How does atomic theory explain temperature and pressure?
• Compare Aristotle's concept of motion with Newton's. Use a falling rock as an example and describe Aristotle's versus Newton's view.
• What is entropy? What does it mean to state that Newtonian physics is time reversible? Give an example of a irreversible event.
• What is Newton's description of gravity? How does Einstein describe gravity?
• What is the purpose of science? How do we distinguish it from pseudoscience? Give an example of a non-scientific experiment and explain why it is non-science.
• Galileo stated that `God's mind contains all the natural laws and that through the occasional glimpses of these laws that the human investigator may laboriously achieve the proofs of the Deity'. How does this statement indicate that Galileo was a Platonist? Describe how Galileo differed from other pure Platonists.
• Describe how conservation laws lead to a clockwork Universe.
• What is light? Describe two of its wave-like properties.
• What are time dilation and Lorentz contraction? How do these demonstrate that space and time are connected?
• For the following cart and track setup below, draw a plot of distance, velocity and acceleration for the cart as pushed uphill from A, stopping at B and back to C. Mark A, B and C on your plots.
• Provide three reasons why mathematics is the language of science. What is the difference between the Platonic and Physical Worlds?
• How is the field concept used in electric and magnetic fields? What is light? What aspect to light indicates a particle nature?
• What is an irreversible system? How do they relate to the arrow of time? What is entropy?
• What theories brought together space and time, then energy and matter, finally all four? How does general relativity explain gravity? What is a black hole to Newton? to Einstein?
• What is reductionism? What is determinism? Explain how atomic theory and Newtonian mechanics combine for rigid determinism.
• How do we distinguish between pseudoscience or non-science?
• Compare the Platonic and non-Platonic views.
• Describe how the premise that the speed of light is constant in all frames leads to time dilation.
• Describe reductionism and determinism. How does one lead to the other?
• Compare and contrast the platonic world with the physical world. Explains the role of mathematics in this view.
• Describe the macroscopic properties of the Ideal Gas Law. Describe the microscopic interpretation of the same law.
• Draw a spacetime diagram of a rocket moving at 0.99c from star A to star B, then going back in time to return to star A at the moment it left.
• State, in the simplest terms, the characteristic of a non-linear or chaotic system.
• What is a Law of Nature? How do we use a scientific theory to relate Nature?
• What are Plato's proposed elements that make up the Universe? Why does he propose five of them? How does this develop into his cosmology?
• Compare atomic theory as outlined by the Greeks (Democritus) versus the modern view (Dalton). What is the cause of pressure and temperature from atomic theory?
• Sketch the process of evolution. Use the words; mutation, gradualism, selection, gene, populations.
