Dear Dr. Science,
How come no matter which direction I ride my bicycle,
the wind blows against me?
--from Christopher Coughlin of Colorado Springs, CO
A: Were you born after 1950? I detect in your question a kind of "the world owes me a living" whine that's so prevalent in people of that generation. Instead of feeling gratitude for the fact that you have a bicycle, or two legs to ride it, you complain that bike riding moves you through the sea of air, producing the effect of a wind on your face. If you rode your bike in a vacuum, the troublesome wind would vanish, but the cumbersome life support system you'd have to wear to accomplish this would make a little headwind seem like a blessing.
