From previous years: 

*Here    is a good blog post on prayer flags and prayer wheels, with gorgeous photographs if the Himalaya Mountains. Someone came up with the idea of the "prayer wagon": drawings   here    and here.     Relatedly, the parable of   Lazarus and the Rich Man (Luke)   came up in class.   
*WORDS: Amiable, endless loop.  
 
*   "When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much he had learned in seven years."  Mark Twain, "Old Times on the Mississippi,"  Atlantic Monthly, 1874.     

*Homework 7 (exponents, neatness)
*Python Code
   print("Buddhist  code.")
   x = 4
   item=1
   while x<6:
   print("Glory to God in the highest!",item)
   item = item +1
   print ("The End.") 

*Steps in solving word problems: 1. Figure out what the question is and what kind of number is supposed to be the answer. 2. Figure out which numbers in the question are relevant--- some numbers might well be irrelevant to getting to the answer. 3. Figure out what techniques you are going to need, e.g., addition, division, Python coding, looking up something on the Internet.  

*1/2-hour Zoom lecture on Python plotting.
