Yesterday, I mentioned some the benefits of being home alone while Kellie takes a vacation without me. But there are also some disadvantages:
- Day old oatmeal sticks to a pot like cement.
- With Kellie gone, her dogs follow me everywhere.
- My bed is cold, and spooning with the dogs isn't much fun.
- Three nights by myself = Three nights of eating ravioli. It would have been four nights, but our friends, Dave and Melissa, feed me dinner yesterday.
- I have not learned how to make a half a pot of coffee that doesn’t taste like mud or coffee colored water.
Apparently, the coffee to water ratio is not linear as you vary the number of cups brewed. I could do some experiments to derive an equation that describes the coffee concentration as function of: the number of cups brewed, the quantity of beans, and the fineness of the grind used to brew the coffee. Mathematically, it might look like this:
coffee concentration: f(j, o, e) = ajx + boy + cez
a, b, and c are coefficients
j = number of java beans used
o = ounces of water used
e = effective cross section of the ground beans
I need to find a way to measure the concentration of the coffee. If the concentration is inversely proportional to the amount of light that can pass through a given quantity of brew, then I could use a laser and a light detector to measure the concentration. Once I’ve brewed enough coffee to collect sufficient data, I can do a regression analysis in Excel to derive the needed equation. Or, I could just go to Starbucks.
I think, maybe, Kellie should come home soon.
