Tuesday,

Thingy & Unthingy Things: Particles & Information * * * Shaking & Meddling: 
, Physics 203, or some roughly equivalent calculusbased study inClassical Mechanics, recalling and reviewing particularly: 1) Galileo's Principle of Relativity, 2) Newton's 2nd Law of Motion, 3) The Theorem of Energy Conservation. Feel comfortable with the meaning and application Universal Gravitation (Newton) & Elasticity (Hooke) * * * HRW: Chapter 15 
Welcome (Back):
* * * 1. Oscillation: 2. Interaction: 
F =  kx 

Thursday 2017

Space as Clocks * * * Bridge Topics (the paths from 'Thingy' things to the ways to proceed in understanding and/or practical reality from the standard motion of discrete particles to the propagation of immaterial pulses) > A Differential Equation. 
HRW: Chapter 13 NOTE: These two chapters seem OUT of ORDER. This is intentional. After Next Tuesday's Lecture, you will have a greater sense for which sections of the above chapters are being emphasized and which are not: GO BACK and REALLY READ the sections it seems that we are emphasizing. REALLY READ means (among other things): Pick at least two Sample (Solved) Problems and try to solve them without looking. 
1. Oscillation: 2. Interaction: 

TUESDAY, SEPTEMBER 5 2017 
The two topics are: 1) Simple Harmonic Oscillation and 2) Universal Gravitation For the moment, regard these as two separate and independent topicstwo pieces we need to begin this course. We will soon bring them together. 
Some Solutions: 
Practice: Simple Harmonic Oscillation The following "Problems" (not "Questions") at the end of Chapter 15. a) Problem 9. b) Problem 29. c) Problem 31. * * * Universal Gravitation Problems at end of Chapter 13: Problems 3, 19, 24, 31 KETCHUP!

A Closer Look at This Differential Equation (the Dif. Eq. for S.H.O.):
 Any variable which depends on time in a manner that can be described by the mathematically generalized form (Dif. Eq.) of Hooke's Law will necessarily oscillate in value with an

Bridge Topic > #2. 'ActionAtADistance': UNIVERSAL GRAVITATION. Any and every infinitely small point of mass exerts an infinitely farreaching influence throughout the universe  pulling toward itself every other point mass, without need for nor interference from any other matter that might be found to intervene. *** Chapter 16

With moral support implied by the sheet entitled "Knowing What To Do When You Don't Know What To", one step at a time. Hint: The smaller each step, the better.

Note how the tail end of the assignment refers to a 'DERIVATION' (PROOF) in the text regarding WAVE MOTION. This is serious and real. You ARE responsible for this challenging proof. Look up other versions wherever you want, but you MUST have a clear notion of where you DO and where you DO NOT understand the proof. Then we can help.
