Week of January 15, 2018

This will be a four-day week as we pause on Monday to pay respects to the life and legacy of Dr. Martin Luther King, Jr.

This Week on Physics
For Tuesday please complete Unit 4 assignment 1 and goal set 1. (Both are due at the start of class on Tuesday.) We will take a quiz over goal set 1 on Wednesday or Thursday, as announced in class. For Wednesday please take notes on PODCAST 2: Work-Energy Theorem. We will go over this and will then do 
assignment 2. Time-permitting we will perform the Work-Energy Theorem experiment. (If we don’t get to it this week, we will do it next week.)

Cool Science of the Week
I don’t know about you, but when it’s as cold outside as it’s been lately, I love to comfort myself with a nice, sugary, hot beverage. One chilly day in 2016 an engineer poured himself a latte and discovered a strange phenomenon: The latte formed striped layers! Being an engineer he used his scientific resources to figure out why and ultimately discovered that lattes can undergo a process that involves both fluid mechanics and thermodynamics, a process called double-diffusive convection. This process is similar to the one that creates the weird hot/cold layers that freak you out when you swim in Lake Erie!
