We have 8 weeks in the summer semester and 5 lecture periods a week.
So about 40-1=39 lecture periods where the subtracted period is for the July 4 holiday.
Since we are planning on covering chapters 23--34 (12 chapters) we will cover about a chapter every 3 days.
But that's why we have courses, to yoke ourselves together like mule team and just drive forward to the the end in a finite time.
And it's all great stuff: intellectually exciting, vital for education and career.
Some parts of chapters may be assigned as readings with NO in-class lecturing on them.
