 Organization

 Pick a schedule. The official course calls for 6 hours per week. Five hours per week will be graded as lab/quiz time, and one hour will be awarded extra credit. Strong students might be able to miss more days.
 Would it be possible to for every student to attend half of the 3:304:30 time slot for a quiz on MW?
 First test this Friday (see for Calandar for entire test schedule)
 Today's lablearning python
 Decible scale problems using copyAndRename.py and DoNotEdit.py. First look at some sandbox codes:

Not important any more 

In particular, we will look at w:Capacitor to understand energy storage using differentials. Then we will check d_cp2.8 #4 to see if maybe it was right. Conventional (and correct) wisdom is that there are four fundamental forces. But as a practical matter, there is: gravity, electromagnetic, chemical, and what might be called "mechanical". These mechanical forces include tension, friction, and the normal force. These mechanical forces, as well as the "chemical" force are for the most part electromagnetic: It is the electrons that prevent you from walking through walls and closed doors, and their force is largely electrostatic. An important chemical force is related to something called the "chemical potential", discussed in this Khan Academy unit. String tension best viewed as a mysterious "mechanical" (not electrical) force, it is best to view the force exerted by ATP in the cell as sort of a "mechanical" force because it is a really complicated way we use food to maintain the proper balance of ions inside and outside a cell, and ultimately control our muscles. The membrane of a biological cell is essentially a capacitor, and there is an obvious electrical force (and associated potential) that pushes positive and negative ions between the intra and extra cellular environments. Also important is the electrochemical gradient, caused by an abundance of one species in one of the environments. See also: w:Electrochemical gradient  w:Active transport  The electrochemical gradient consists of two parts, the chemical gradient, or difference in solute concentration across a membrane, and the electrical gradient, or difference in charge across a membrane.

T7 will be on Monday 6/24 so we can stay on schedule. After this, (starting with T8), exams will begin to cover review material. Expect lower scores, but do not worry: All members of this class have demonstrated an ability to pass this course. The "harder" tests will be used to distinguish between the passing grades ... all you need to do to pass this course is continue to do well on the new "essential" questions.

Gauss and Ampere Laws  

Assume that A (SI unit: m^{2}) is a small surface centred at a given point M and orthogonal to the motion of the charges at M. If IA (SI unit: A) is the electric current flowing through A, then electric current density j at M is given by the limit with surface A remaining centred at M and orthogonal to the motion of the charges during the limit process.S
What the ...? where μ is a material dependent parameter called the permeability. In some cases the permeability may be a second rank tensor so that H may not point in the same direction as B. These relations between B and H are examples of constitutive equations. However, superconductors and ferromagnets have a more complex BtoH relation; see magnetic hysteresis.
