Some rewards are better than others

The first reward was a delicious cup of coffee and a cinnamon roll.  After talking to the nice ladies administering the voting process and pushing buttons on the machine, I sauntered over to the coffee shop.  Sat on the outside deck to sip, chew and read Facebook on my phone.  I was oblivious to the rain, which it turns out was my second reward, because of the large live oaks and umbrellas over the table.

Weather control

Didn’t realize I had been granted power over the weather.  As soon as I put on my rain jacket and set out for home the rain let up.  OK.  Unzip the jacket to get some ventilation, and the rain starts up again.  Zip up the jacket, rain ceases.  Sigh.

A choice of how you get wet

So the question is not about avoiding being wet, it’s about how you’re going to get wet.  Do you let the rain fall on you or do you sweat inside a “breathable” rain jacket?

W represents wetness.

Rain:

• v is average velocity of cyclist
• r is rain rate
• s is duration of stoplights
• n is number of stoplights and stop signs
• a is absorption rate of cotton clothing

Jacket:

• p is amount of sweat based on v
• h is ambient humidity
• h’ is humidity inside jacket
• b is vapor transportation rate of jacket

Solve for W in both cases and compare.

The intangible was the attention getting property of the retina searing neon glow orange of the rain jacket.
