Some Curiosity Stoppers I've Heard
A curiosity stopper is an answer to a question that gets you to stop asking questions, but doesn’t resolve the mystery.
There are some curiosity stoppers that I’ve heard many times:
- Why doesn’t cell phone radiation cause cancer? Because it’s non-ionizing radiation.
- Why are antioxidants good for you? Because they eliminate free radicals.
- Why do bicycles stay upright? Because of gyroscopic forces.
- Why do solids hold together? Because of intermolecular forces of attraction.
For the first three, those answers confused me because I didn’t know what those words meant. I guess I know what an ion is (it’s an atom with an electrical charge) but why do I care whether radiation is ionizing? And what makes radiation ionizing or non-ionizing?
What’s a free radical? Why is it bad?
What’s a gyroscopic force? (What even is a gyroscope? It’s some sort of top, right?) How on earth does a bicycle generate a gyroscopic force?
The fourth curiosity stopper—”intermolecular forces of attraction”—is even more of a non-answer. Of course solids hold together because a force holds them together. That’s what a force is. But what is the force, and where does it come from?
Another genre of curiosity stopper is the out-of-context number:
- “The Dow is down 600 points today.” (How much is that?)
- “My proposed policy will create two million jobs.” (What percentage is that? What are the odds that I, personally, get a new job?)
- “This product has 7 grams of protein per serving!” (How big is a serving? How much would I need to eat to meet my daily protein requirement?)
