When it comes to science, temperature matters. And when it comes to Wisconsin, things get really, really cold. When the temperature drops, the world around us changes in a practical and scientific sense. For instance, my car is less likely to work (though that may be a function of age rather than weather), and the percentage of water maintaining a crystalline configuration goes up. There are a lot of things to wonder about how a cold world functions, scientifically. These are some of my questions, and their answers:
1. Will the gasoline in my carís tank actually ever freeze into a gas-cube?
2. Why is wool so warm?
3. Why do some snowflakes look intricate and lacy, while others seem shapeless?
