Practical mathematical applications

The weather made a radical change yesterday, turning cold and rainy --- more like December than March. Today the sun was back, but it was still cold and windy. When I left the house to walk, it was 49 degrees with a wind chill factor of 41 degrees.

The first leg of my walk is 1.4 miles and I had the wind behind me, pushing me along, and was able to trot using roughly the same amount of energy as brisk walking. That was the good part.

When I made the loop to start the 1.6 mile return to home base, I was walking straight into the teeth of those 30 mph wind blasts. I'm not an engineer, but I figure I'm walking in one direction at 3.8 mph, and the wind is blowing in the opposite direction at 30 mph... well, you do the math.

The best analogy I can come up with is that my trip home today was like walking 1.6 miles in a shoulder-deep pool of tapioca pudding. By the time I walked into the house, I felt like I'd been dragging an anti-freeze can full of concrete, like the one my dad used as a boat anchor when I was a lad.

I don't know exactly how it works, but I believe whoever's in charge of life should award bonus points to older men who spend thirty minutes walking into the wind.

PS: When I was a little boy, I dropped that boat anchor on a toad to see what would happen. Maybe atonement requires walking long distances into bitterly cold winds... you think ?

Summer walks in Texas

Judging by the amount of water on driveways and sidewalks and in the street, some Texans seem to think you can grow concrete and asphalt using lawn sprinklers.
